The present work aimed to document the facies development and sedimentology of the Raghama carbonates exposed along the eastern coastal plain of the Red Sea, northwestern Saudi Arabia. Four stratigraphic sections were measured and sampled(D1–D4) and thin sections and major and trace element analyses were prepared and applied for petrographic and geochemical approaches. The carbonates were subdivided into three successive fore-reef, reef-core, and back-reef depositional facies. Sandy stromatolitic boundstone, microbial laminites, dolomitic ooidal grainstone, bioclastic coralline algal wackestone, sandy bioclastic wackestone, and coral boundstones were the reported microfacies types. Petrographic analysis reveals that the studied carbonates were affected by dissolution, dolomitization, and aggrading recrystallization, which affects both the original micrite matrix and grains or acts as fracture and veinlet filling leading to widespread vuggy and moldic porosity. No evidence of physical compaction, suggesting rapid lithification and recrystallization during early diagenesis and prior to substantial burial and intensive flushing by meteoric waters. Most of the original microstructure of corals were leached and destructed. This is indicated by the higher depletion in Sr and Ca levels and increase in Mg,Na, Fe, and Mn levels, especially in section D1, in comparison with the worldwide carbonates.展开更多

At least one in five Saudis, suffer from diabetes. “Diabetes is a pandemic of unprecedented magnitude spiraling out of control” (Boulton). Saudi Arabia ranks the second highest in the Middle East, and is the seventh in the world for the prevalence of diabetes (WHO). Diabetes mellitus (DM) has been found to be related to high mortality, morbidity accompanied by poor general health and lower quality of life. Current Saudi diabetes patients’ behaviors, practices, and beliefs regarding foot health problems such as ulcers, are not well investigated. Diabetic patients frequently utilize natural remedies and Herbs for self-medication as a part of complementary and alternative Medicine. Aim of study: To explore the widespread use of the alternative remedies in the local communities of the Western Saudi Arabia, the drives behind using and to focus on the potential adverse effects following their usage. Method: A descriptive, cross-sectional study of 386 diabetic patients with feet problems in Makkah Region, West of Saudi Arabia during the period April - June 2023. Results: Out of the 531 participants, only 386 participants reported diabetic foot disorder (DFD). Most of the participant were above 65 years of age group (24.61 %). Male (52.08%) more than female (47.92%) in the research group. All of the participants had diabetic foot disorders at least once. The prevalence of complementary and alternative medicines (CAM) use among them was 67.88%, as solitary or in combination with hospital medicines. Honey headed the list followed by myrrh and black seeds. Acquaintances advice (59.54%) was the most reason for using the alternative medicine. 60.30% of Diabetic foot patient complained of adverse effects during CAM remedies use. Conclusion: Consumption of CAM remedies among diabetic patients for Diabetic Foot Disorder (DFD) is common. Honey headed the list followed by myrrh and black seeds. Additional wide-scale research is required to establish their actual efficacy, safety and potential adverse out-comes and to generalize the outcomes.展开更多

It is often associated with certain adverse reactions (urinary tract infection (UTI), diabetes ketoacidosis (DKA), and genital infections). Thus, the Saudi Food and Drug Administration requested a post-authorisation safety study to monitor the safety of empagliflozin during the defined observation period. Methodology: The local, comparator, non-interventional, regulatory post-marketing study using “new user” design was conducted in patients with T2DM, treated with empagliflozin (10 or 25 mg) and dipeptidyl peptidase-4 (DPP-4) inhibitors (NCT03764631). Study was conducted from 2018 to 2020, wherein each patient was followed up for 12 months after the index period. Incidence and occurrence of DKA, severe UTIs, volume depletion and dehydration were observed along with metformin, insulin and treatment complexity status and adverse events in the index and Ramadan period. All data collected were analysed using descriptive statistics. Results: Among the 1502 patients enrolled (empagliflozin [n = 751] and DPP-4 inhibitors [n = 751]), 0.1% patients (n = 1) in each group and Conclusion: Empagliflozin was well tolerated over a period of 12 months, with no safety concerns and a favourable benefit/risk ratio.展开更多

It sheds light on the potential cybersecurity risks and how parental perception impacts children’s willingness to adapt cybersecurity features. By instilling the significance of cybersecurity awareness in early stages, society can provide children with the necessary skills to navigate the digital realm responsibly. As we progress, ongoing research and collaborative endeavors will be pivotal in formulating effective strategies to shield the digital generation from the potential pitfalls of the virtual realm. Regular Internet usage is essential for various purposes such as communication, education, and leisure. The cohorts of Generation Z and Alpha were born during a period of exponential Internet growth, leading them to heavily engage with the Internet. Consequently, they are equally vulnerable to cybersecurity threats just like adults. Addressing potential security risks for today’s youth becomes the responsibility of parents as the primary line of defense. This research focuses on raising awareness about the imperative of ensuring children’s safety in the online sphere, particularly by their parents. The study is conducted within the specific context of Saudi Arabia, aiming to examine how Saudi parents’ perception of cybersecurity influences their children’s cyber safety. The study identifies critical factors, including attitudes towards cybersecurity, awareness of cybersecurity, and prevailing social norms regarding cybersecurity. These factors contribute to the development of parents’ intention to prioritize cybersecurity, which consequently affects their children’s behaviors in the digital realm. Utilizing a quantitative approach based on a questionnaire, the study employs a Structural Equation Modeling (SEM) framework to analyze the collected data. The study’s findings underscore that parents’ intent towards cybersecurity plays a significant role in shaping their children’s behavior concerning cyber safety.展开更多

The magnitudes of these trends were characterized and tested using Mann-Kendall (MK) rank statistics at different significance levels. During this study period, the mean rainfall in SA showed a slight and significant decreasing trend by about 2 mm/35 years. Investigation of seasonal trends of rainfall revealed that Winter and Spring rainfall decreased significantly by 2.7 mm/35 years and 5.4 mm/35 years respectively. Three months showed very slight significant decreasing trends of rainfall. These were the months of February, March and April. Mann-Kendall analyses were carried out to investigate the annual trends of rainfall during three sub-periods, i.e., 1985-1996, 1997-2008, and 2009-2019. The results revealed that while rainfall increased by 5.3 mm/12 years and 7.8 mm/11 years for the first and the third periods respectively, it decreased by about 11 mm/12 years during the second period. While trends of rainfall in Saudi Arabia are affected by large scale circulations and local factors, the effect of extraterrestrial factors, such as solar activity and its consequent effects on the climate may, additionally, play a potential role in affecting the pattern of rainfall in Saudi Arabia.展开更多

The results show that the strength, magnitude, proportion and statistical significance of the relationship between precipitation and the two variables varied by season and month. We find that mean annual precipitation in Saudi Arabia, from May to November, and summer and autumn are correlated with cosmic rays and inversely correlated with SSN. Correlations of varying intensities and scales were found during the remaining months and during winter and spring. The relationships between the rainfall and SSN and CR for each solar cycle were investigated and showed that for all three cycles, the annual rainfall over Saudi Arabia has a positive correlation with CR. Different results were obtained when the seasonal rainfall data correlated with the SSNs and CRs during each cycle. The results obtained, in terms of their strength and magnitude, are affected by terrestrial and extra-terrestrial factors. These factors have been briefly presented and discussed. These findings represent a step towards understanding the possible role of solar activity in climate change for future meteorological phenomenon forecasting, even if the physical mechanism is still poorly quantified.展开更多

The Geographic Information System (GIS) technology has been applied to investigate the spatial distribution of some selected public services over the municipal election areas within Makkah city, Saudi Arabia. These services include education, health, security, religious, commercial, and sports services. The attained results show that except for religious services, other public services are not quantitatively proportional with the population variations in Makkah. It has been found that the third election area posses almost one third of five public services and two thirds of the sport services. That might be attributed to the fact that the third election area possesses almost a quarter of the city population. But, although the first election area has a closer percentage of the total population, it does not include a comparable percentage of public services. On a spatial basis, results of GIS spatial analysis (particularly the Euclidian distance, the mean distance band to a neighbor, the standard distance, the directional distribution ellipse, and the average nearest neighbor ratio tools) have concluded that there is inequity in the services distribution over municipal election areas in Makkah city. Consequently, it is recommended that local planners and decision makers should take the obtained results into consideration to achieve fair and better distribution of public services in the city.展开更多

文摘Ragahama Formation comprises a siliciclastic continental deposits followed by marine carbonates, representing prograding alluvial fans from adjacent high hinterlands seaward into lagoons and fringing reef environments. The present work aimed to document the facies development and sedimentology of the Raghama carbonates exposed along the eastern coastal plain of the Red Sea, northwestern Saudi Arabia. Four stratigraphic sections were measured and sampled(D1–D4) and thin sections and major and trace element analyses were prepared and applied for petrographic and geochemical approaches. The carbonates were subdivided into three successive fore-reef, reef-core, and back-reef depositional facies. Sandy stromatolitic boundstone, microbial laminites, dolomitic ooidal grainstone, bioclastic coralline algal wackestone, sandy bioclastic wackestone, and coral boundstones were the reported microfacies types. Petrographic analysis reveals that the studied carbonates were affected by dissolution, dolomitization, and aggrading recrystallization, which affects both the original micrite matrix and grains or acts as fracture and veinlet filling leading to widespread vuggy and moldic porosity. No evidence of physical compaction, suggesting rapid lithification and recrystallization during early diagenesis and prior to substantial burial and intensive flushing by meteoric waters. Most of the original microstructure of corals were leached and destructed. This is indicated by the higher depletion in Sr and Ca levels and increase in Mg,Na, Fe, and Mn levels, especially in section D1, in comparison with the worldwide carbonates.
文摘Newborn hearing screening(NHS) programs are essential to identify hearing loss early in life and to improve outcomes in children. In Saudi Arabia, the national NHS program has been operational since 2016;however, few studies have evaluated its status, and none have covered all provinces across the country. This cross-sectional retrospective study provides an overview of the program's status across all provinces, focusing on screening coverage rates, referral/fail rates, and follow-up procedures. In 2021, 199,034 newborns were screened, with a coverage rate of 92.6% and an overall referral/fail rate of 1.87%. These performance measures provide a foundation for future progress and improvements. This study highlights the importance of ongoing efforts to enhance the program's effectiveness and sustainability.
文摘Diabetes is a chronic condition that is significantly impacted daily by environment. At least one in five Saudis, suffer from diabetes. “Diabetes is a pandemic of unprecedented magnitude spiraling out of control” (Boulton). Saudi Arabia ranks the second highest in the Middle East, and is the seventh in the world for the prevalence of diabetes (WHO). Diabetes mellitus (DM) has been found to be related to high mortality, morbidity accompanied by poor general health and lower quality of life. Current Saudi diabetes patients’ behaviors, practices, and beliefs regarding foot health problems such as ulcers, are not well investigated. Diabetic patients frequently utilize natural remedies and Herbs for self-medication as a part of complementary and alternative Medicine. Aim of study: To explore the widespread use of the alternative remedies in the local communities of the Western Saudi Arabia, the drives behind using and to focus on the potential adverse effects following their usage. Method: A descriptive, cross-sectional study of 386 diabetic patients with feet problems in Makkah Region, West of Saudi Arabia during the period April - June 2023. Results: Out of the 531 participants, only 386 participants reported diabetic foot disorder (DFD). Most of the participant were above 65 years of age group (24.61 %). Male (52.08%) more than female (47.92%) in the research group. All of the participants had diabetic foot disorders at least once. The prevalence of complementary and alternative medicines (CAM) use among them was 67.88%, as solitary or in combination with hospital medicines. Honey headed the list followed by myrrh and black seeds. Acquaintances advice (59.54%) was the most reason for using the alternative medicine. 60.30% of Diabetic foot patient complained of adverse effects during CAM remedies use. Conclusion: Consumption of CAM remedies among diabetic patients for Diabetic Foot Disorder (DFD) is common. Honey headed the list followed by myrrh and black seeds. Additional wide-scale research is required to establish their actual efficacy, safety and potential adverse out-comes and to generalize the outcomes.

文摘AIM:To investigate the practice patterns of optometrists in Saudi Arabia regarding myopia management.METHODS:An internet-based survey was distributed to all practicing optometrists in Saudi Arabia(n=1886).The survey contained questions related to 1)demographics,2)knowledge about myopia and its associated complications,3)current clinical care,4)type and frequency of myopia treatment prescribed,and 5)potential barriers limiting treatment adoption.RESULTS:The completed surveys were collected from 171 optometrists(9.06%response rate,60%male).Knowledge regarding myopia-associated complications was prevalent but somewhat inaccurate among the respondents.Cycloplegic refraction at initial visit was used by 59%of the respondents.The cover test was the most reported binocular vision test(83%),and 38%of optometrists did not perform any ocular biometrics.Twothirds prescribed single-vision spectacles for children with myopia.Increased time spent outdoors was selected by 80%of the practitioners who prescribed myopia control treatment as the primary approach.Insufficient support and lack of clinical experience in providing myopia treatment were reported as the most important factors limiting the adoption of myopia management strategies.CONCLUSION:The current optometric practices in Saudi Arabia require further investigation.Optometrists appear to be somewhat aware of myopia and the associated risks.However,most evidence-based myopia treatments are not being locally adopted,primarily because of lack of support,lack of experience,and limited availability.
文摘Introduction: Thalassemia disorder is a genetic disease that causes the blood to have less hemoglobin than normal, the main requirement to control thalassemia’s propagation is to educate the entire society. Methodology: A descriptive survey was taken to evaluate the awareness of thalassemia among Saudi Arabia’s society, with a sample size of 384. Results: The results were written in frequencies, and it shows that most of the participants were unaware and lacking information on thalassemia syndrome. Discussion: The results of this study provide valuable insights into the awareness of thalassemia in Saudi Arabia and highlight the need to raise awareness of this disease. Conclusion: This study is not comprehensive because the survey was not disrupted evenly, but it can give us an overview of the awareness of thalassemia in Saudi Arabia, and it shows that most of the participants were unaware and lacked information on thalassemia.
文摘Background: Cardiovascular Disease (CVD) is one of the leading chronic diseases in Saudi Arabia (SA) that cause disability and death. CVD predisposition risk varies according to age, gender, education, socioeconomic factors, and place of residency. In addition, CVD risk factors include physical inactivity, sedentary lifestyle, saturated fatty acid high diet, smoking, and stress. Aim: This is a systematic review study that aims to determine the effect of mindful mediation, physical activity, and diet on CVD in SA. Materials and Methods: This is a systematic electronic search method in Google scholar, PubMed, and Medline. Papers collected are papers that have been published since 2015. The search uses the following keywords: (Cardiovascular disease OR physical activity OR Physical inactivity OR meditation OR diet) AND Saudi Arabia. Data were extracted from each study through a narrative summary of each study. Results: Forty papers collected from 2015 to 2022 were included in the narrative study. Physical activity, diet, and mindful meditation are among the factors that can reduce the risk of development of CVD or severity of disease in patients with a CVD. Conclusion: This systematic review emphasized risk factors like physical inactivity, poor diet, and low level of awareness among Saudis and CVD Saudi patients. The findings show the role of physical activity, mindful meditation, and diet in reducing the onset or severity of cardiovascular disease.
文摘Background: Empagliflozin, a sodium-glucose co-transporter-2 (SGLT2) inhibitor is used as a monotherapy or in combination for lowering the elevated blood glucose level in patients with type 2 diabetes mellitus (T2DM). It is often associated with certain adverse reactions (urinary tract infection (UTI), diabetes ketoacidosis (DKA), and genital infections). Thus, the Saudi Food and Drug Administration requested a post-authorisation safety study to monitor the safety of empagliflozin during the defined observation period. Methodology: The local, comparator, non-interventional, regulatory post-marketing study using “new user” design was conducted in patients with T2DM, treated with empagliflozin (10 or 25 mg) and dipeptidyl peptidase-4 (DPP-4) inhibitors (NCT03764631). Study was conducted from 2018 to 2020, wherein each patient was followed up for 12 months after the index period. Incidence and occurrence of DKA, severe UTIs, volume depletion and dehydration were observed along with metformin, insulin and treatment complexity status and adverse events in the index and Ramadan period. All data collected were analysed using descriptive statistics. Results: Among the 1502 patients enrolled (empagliflozin [n = 751] and DPP-4 inhibitors [n = 751]), 0.1% patients (n = 1) in each group and Conclusion: Empagliflozin was well tolerated over a period of 12 months, with no safety concerns and a favourable benefit/risk ratio.
文摘This paper explores the convergence of Saudi Arabia’s Vision 2030 with the increasing dependence on the Internet for educational purposes. It sheds light on the potential cybersecurity risks and how parental perception impacts children’s willingness to adapt cybersecurity features. By instilling the significance of cybersecurity awareness in early stages, society can provide children with the necessary skills to navigate the digital realm responsibly. As we progress, ongoing research and collaborative endeavors will be pivotal in formulating effective strategies to shield the digital generation from the potential pitfalls of the virtual realm. Regular Internet usage is essential for various purposes such as communication, education, and leisure. The cohorts of Generation Z and Alpha were born during a period of exponential Internet growth, leading them to heavily engage with the Internet. Consequently, they are equally vulnerable to cybersecurity threats just like adults. Addressing potential security risks for today’s youth becomes the responsibility of parents as the primary line of defense. This research focuses on raising awareness about the imperative of ensuring children’s safety in the online sphere, particularly by their parents. The study is conducted within the specific context of Saudi Arabia, aiming to examine how Saudi parents’ perception of cybersecurity influences their children’s cyber safety. The study identifies critical factors, including attitudes towards cybersecurity, awareness of cybersecurity, and prevailing social norms regarding cybersecurity. These factors contribute to the development of parents’ intention to prioritize cybersecurity, which consequently affects their children’s behaviors in the digital realm. Utilizing a quantitative approach based on a questionnaire, the study employs a Structural Equation Modeling (SEM) framework to analyze the collected data. The study’s findings underscore that parents’ intent towards cybersecurity plays a significant role in shaping their children’s behavior concerning cyber safety.
文摘In this study, rainfall data from 19 stations in Saudi Arabia (SA) for the period 1985-2019 was utilized to investigate interannual, monthly, and seasonal rainfall variations and trends. The magnitudes of these trends were characterized and tested using Mann-Kendall (MK) rank statistics at different significance levels. During this study period, the mean rainfall in SA showed a slight and significant decreasing trend by about 2 mm/35 years. Investigation of seasonal trends of rainfall revealed that Winter and Spring rainfall decreased significantly by 2.7 mm/35 years and 5.4 mm/35 years respectively. Three months showed very slight significant decreasing trends of rainfall. These were the months of February, March and April. Mann-Kendall analyses were carried out to investigate the annual trends of rainfall during three sub-periods, i.e., 1985-1996, 1997-2008, and 2009-2019. The results revealed that while rainfall increased by 5.3 mm/12 years and 7.8 mm/11 years for the first and the third periods respectively, it decreased by about 11 mm/12 years during the second period. While trends of rainfall in Saudi Arabia are affected by large scale circulations and local factors, the effect of extraterrestrial factors, such as solar activity and its consequent effects on the climate may, additionally, play a potential role in affecting the pattern of rainfall in Saudi Arabia.
文摘From 2010 to 2016,the proportion of Saudi nursing staff began to decline due to various factors,including the life expectancy of the Saudi population,which has increased from age 69 in 1990 to age 76 in 2012 Also,from 1990 to 2012,Saudi Arabia’s population increased by 2.5%annually,which would result in a rise in healthcare demand.Moreover,the bad image about nursing profession,and the perception that is insignificant profession and less efficient than other occupations,influence the public views to join the nursing discipline.When The Saudi Arabian Vision 2030 was implemented,it positively affected the Saudi economy.Therefore,this study aimed to describe the influence of the Vision on the nursing profession.Secondary data was pulled from the Ministry of Health was used to do a Descriptive Comparative Research Design to compare between the number of nurses when the Vision was implemented with the years after that.Results revealed that the growth rate of the number of nurses increased by 9%to 10%after the implementation of the vision.These findings underscore the well-established policies of the Saudi Arabian Vision 2030 that have a positive impact on the nursing profession.
文摘Chinese President Xi Jinping was invited to Riyadh to attend the first China-Arab States Summit and the first ChinaGulf Cooperation Council(GCC)Summit and pay a state visit to the Kingdom of Saudi Arabia from December 7 to 10,2022.The ThreeRing Summits constitute China’s largest and highest-profile diplomatic initiative for the Arab world since the founding of the PRC.
文摘In this study, annual, quarterly, and monthly mean precipitation data in Saudi Arabia were correlated with sunspot number (SSN) and galactic cosmic ray (CR) flux over 35 years (1985-2019). The results show that the strength, magnitude, proportion and statistical significance of the relationship between precipitation and the two variables varied by season and month. We find that mean annual precipitation in Saudi Arabia, from May to November, and summer and autumn are correlated with cosmic rays and inversely correlated with SSN. Correlations of varying intensities and scales were found during the remaining months and during winter and spring. The relationships between the rainfall and SSN and CR for each solar cycle were investigated and showed that for all three cycles, the annual rainfall over Saudi Arabia has a positive correlation with CR. Different results were obtained when the seasonal rainfall data correlated with the SSNs and CRs during each cycle. The results obtained, in terms of their strength and magnitude, are affected by terrestrial and extra-terrestrial factors. These factors have been briefly presented and discussed. These findings represent a step towards understanding the possible role of solar activity in climate change for future meteorological phenomenon forecasting, even if the physical mechanism is still poorly quantified.
文摘Background:The midwife plays a critical role in health counselling and education,not just for women but also for their families and communities.At the current time,with the growth of the midwifery workforce globally,there is still a lack of understanding regarding the full scope and role of the midwife.Aim:To evaluate the current situation of knowledge of midwives’role among women in Makkah.In addition,this study identifies the effect of women’s knowledge on their preferences for receiving maternity care from health professionals.Methods:This study employed a descriptive quantitative cross-sectional method.The total resultant sample size(N)equalled 379 global respondents,of which 306,with a response rate=of 80.73%completed the entire survey as requested.An electronic questionnaire in the Arabic language was used in this study.Results:Results revealed that most women had incorrect knowledge regarding three aspects of the midwives’roles during pregnancy 53.9%,labour 52.8%and childbirth 61.9%.Also,results presented that most women preferred obstetricians to follow up on an uncomplicated pregnancy,labour,childbirth,and maternity care 69.6%,53.9%,64.7%and 46.1%,respectively.The study found that the women’s knowledge about midwives’roles affects their preferences for healthcare professionals in receiving maternity care(P<0.05).Conclusion:Responses showed that most participants had no experience and had negative views about midwives’roles.Thus,it would affect their health professionals’preferences for receiving maternity care.Therefore,midwifery services and maternity care professionals should prioritize educating women about midwives’competencies in maternity care.
文摘Objective:The present study aimed to address the care of psychiatric patients and its impact on nurses’behavior in Saudi Arabia.Methods:A cross-sectional quantitative questionnaire-based study was conducted.This study was carried out in various government hospitals across different regions of Saudi Arabia.Results:A total of 73 nurses participated in the study,with male nurses comprising the majority(61.6%)compared to females.Being a young nurse or with few years of work experience is linked with more predilection towards preventive behaviour and/or physical activity.A significant mean difference was observed,indicating higher scores for preventive behavior among females(female 14.93±5.82 vs.male 11.56±5.48,P=0.015).The Bonferroni post hoc multiple comparisons did not reveal any statistical significance for single vs.married(P=0.618),single vs.divorced(P=0.223),and married vs.divorced(P=0.020).Conclusion:The study results demonstrated a significant impact of caring for psychiatric patients on nurses’behavior.This is concerning because psychological and mental health strain has been shown to contribute to unhealthy lifestyle habits,such as physical inactivity and sleep deprivation,which,in turn,can contribute to the increasing incidence and prevalence of chronic diseases.Healthcare interventions targeting psychiatric and mental health nurses should be designed and examined to emphasize the importance of healthy lifestyle choices and an active lifestyle.
文摘The study area is a part of the Arabian Shield rocks of west central part of Saudi Arabia (150 km to the northeast of Jeddah). Geologically, the study area comprises five main geologic units i.e. 1) Layered basic volcanics and related volcaniclastics which are composed mainly from intercalated basalts and andesites and the related volcaniclastic derivatives, 2) Acidic volcanics and related volcaniclastics which are composed from layered and laminated dark and light acidic to intermediate igneous rocks, quartz and chert and marbles, 3) The Tertiary sedimentary succession which of volcaniclastic red beds and the intercalated clays;5) Tertiary volcanics of Harrart, and 4) The Quaternary wadi fill deposits which are composed from friable pebble supported conglomerates, sandstones and clays. Hydrogeologically, the groundwater aquifer of Wadi Qudaid is present mainly in two main horizons i.e. i) unconfined shallow aquifer (13 - 37 m) within the well porous and permeable conglomerates of the Quaternary Wadi deposits, ii) The deep confined aquifer of the bedded tuffaceous sandstones and mudstone of the Tertiary sedimentary succession of Ash Shumaysi Formation. The water samples are analyzed for major elements i.e. Ca, Mg, Na, Cl, SO4, HCO3 and the results show the normal content of these elements. The study related the addition and depletion of many elements during the running trip of the groundwater from the northeast (recharge area) to the southwest (downstream) area.
文摘The current study aimed at evaluating the capabilities of seven advanced machine learning techniques(MLTs),including,Support Vector Machine(SVM),Random Forest(RF),Multivariate Adaptive Regression Spline(MARS),Artificial Neural Network(ANN),Quadratic Discriminant Analysis(QDA),Linear Discriminant Analysis(LDA),and Naive Bayes(NB),for landslide susceptibility modeling and comparison of their performances.Coupling machine learning algorithms with spatial data types for landslide susceptibility mapping is a vitally important issue.This study was carried out using GIS and R open source software at Abha Basin,Asir Region,Saudi Arabia.First,a total of 243 landslide locations were identified at Abha Basin to prepare the landslide inventory map using different data sources.All the landslide areas were randomly separated into two groups with a ratio of 70%for training and 30%for validating purposes.Twelve landslide-variables were generated for landslide susceptibility modeling,which include altitude,lithology,distance to faults,normalized difference vegetation index(NDVI),landuse/landcover(LULC),distance to roads,slope angle,distance to streams,profile curvature,plan curvature,slope length(LS),and slope-aspect.The area under curve(AUC-ROC)approach has been applied to evaluate,validate,and compare the MLTs performance.The results indicated that AUC values for seven MLTs range from 89.0%for QDA to 95.1%for RF.Our findings showed that the RF(AUC=95.1%)and LDA(AUC=941.7%)have produced the best performances in comparison to other MLTs.The outcome of this study and the landslide susceptibility maps would be useful for environmental protection.

文摘Objective:To detect Coxiella burnetii(C.burnetii)DNA in clinical specimens from camel,goats,cattle and sheep in the Kingdom of Saudi Arabia.Methods:A total of 367 clinical samples including blood,milk,faeces and urine were collected from different livestock and subjected to PCR amplification using primers which amplify transposon-like region and transposase gene.Results:Positive amplification from both regions was obtained from camel,goats and cattle but not from sheep.A percentage of 10.8%samples yielded positive PCR amplification from both blood and milk,where 15 of 139 blood and 16 of 148 milk samples were positive.Faeces and urine showed higher percentages of positive samples reaching 40.8%and 23.8%respectively.Conclusions:The preferred route of shedding in camel appeared to be the faeces followed by urine,while that of goats appeared to be the faeces and that of the cattle appeared to be the milk.
文摘The spatial fairness of public services is a major aspect in offering a healthy and cheerful living environment in a city. The Geographic Information System (GIS) technology has been applied to investigate the spatial distribution of some selected public services over the municipal election areas within Makkah city, Saudi Arabia. These services include education, health, security, religious, commercial, and sports services. The attained results show that except for religious services, other public services are not quantitatively proportional with the population variations in Makkah. It has been found that the third election area posses almost one third of five public services and two thirds of the sport services. That might be attributed to the fact that the third election area possesses almost a quarter of the city population. But, although the first election area has a closer percentage of the total population, it does not include a comparable percentage of public services. On a spatial basis, results of GIS spatial analysis (particularly the Euclidian distance, the mean distance band to a neighbor, the standard distance, the directional distribution ellipse, and the average nearest neighbor ratio tools) have concluded that there is inequity in the services distribution over municipal election areas in Makkah city. Consequently, it is recommended that local planners and decision makers should take the obtained results into consideration to achieve fair and better distribution of public services in the city.
