Effect of Neighboring Footings on Single Footing Settlement
The most economic type of foundations is shallow isolated footings. It is common practice to estimate settlement of shallow isolated footings without consideration of the influence of neighboring footings or loaded areas. In fact there is few, if any, available method to estimate settlement of isolated footings taking into consideration such an effect of neighboring loaded areas. Such an effect might be vital in a lot of cases. This paper presents a case history that shows the importance of such an effect. The case history in hand consists of 28 auxiliary buildings of an Electrical Power plant near Cairo, Egypt. A total of 175 boreholes were drilled to characterize the ground conditions in the site. The maximum allowable settlement was one of the major criteria of the project. Settlement analysis had to be carried out for each of the project building. In each building, the settlement was calculated under the center of each footing due to the load imposed from the footing and that due to the stresses on the surrounding footings of the structure. In addition, Settlement was computed for the case of single footing without influence of surrounding loaded footings as the case of the common practice in the geotechnical engineering profession. Settlement analysis was carried out by computing a profile of elastic stress increase due to all loaded areas at the foundation level. Settlement at a point is then computed at the foundation level by integrating vertical strains of the layered ground under the footing. The results of the analysis suggested that the effect neighboring footings could be important to the extent that necessitates the change of the foundation system from isolated footings to raft foundation in the light of the maximum allowable settlement of each foundation system
Curcumin protection activities against Îł-Rays-induced molecular and biochemical lesions
BACKGROUND: Curcumin is a yellow-pigment phenolic compound used as a food spice and has a broad spectrum of antioxidant, anti-carcinogenic, anti-mutagenic and anti-inflammatory properties. METHODS: Radio-protective efficacy of curcumin; diferuloylmethane (C(21)H(20)O(6)) was evaluated using molecular and biochemical assays in male mice after exposure to 3Â Gy Îł-rays. Curcumin was given at a dose of 400Â ÎŒmol/ kg body weight via gastric tubes for 5 following days either pre-, post- or both pre- and post-exposure. RESULTS: The incidence of aberrant cells and aberration types (mostly chromatids, breaks and fragments) was reduced with curcumin dosage as compared to irradiated group. Thiobarbituric acid reactive substances (TBARS), hydroperoxide (HP), xanthine oxidase (XO) and apoptotic markers (DNA- fragmentation and caspase-3 activation) were increased significantly, whereas levels of glutathione (GSH) and the enzymatic antioxidants [Superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx)] were significantly depleted in Îł-irradiated mice. Curcumin treatments of mice groups including the 5Â days pre-irradiation treated group (protected), the 5Â days post-irradiation treated group (treated), and the curcumin treated group 5Â days pre- and post-irradiation (protracted), have attenuated the liver toxic effects of Îł-rays as manifested by reducing the levels of TBARS, HP, XO and DNA fragmentation. Curcumin has also rescued the depletion of GSH and the enzymatic-antioxidant status. CONCLUSIONS: Curcumin has significant radio-protective and radio-recovery activities in Îł-irradiated mice. It has antioxidant potential against Îł-rays-induced cytogenetic, molecular and biochemical lesions in mice

Researchers Supporting Project number (RSPD2023R655), King Saud University, Riyadh, Saudi Arabia.Supplementary Materials: The following supporting information can be downloaded from: https://www.mdpi.com/article/10.3390/molecules28155749/s1The incorporation of fermented camel milk with natural additives possesses numerous benefits for the treatment of various pathological and metabolic conditions. The present study investigated the impact of fortification of fermented camel milk with sage or mint leaves powder (1 and 1.5%, respectively) on glucose and insulin levels, lipid profile, and liver and kidney functions in alloxan-induced diabetic rats. The gross chemical composition of sage and peppermint leaves powder was studied. The chemical composition of sage and mint extracts was performed using liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-MS) of sage and mint extracts. Furthermore, a total of forty-two adult normal male albino rats were included in this study, whereas one group was kept as the healthy control group (n = 6 rats) and diabetes was induced in the remaining animals (n = 36 rats) using alloxan injection (150 mg/kg of body weight). Among diabetic rats groups, a control group (n = 6 rats) was kept as the diabetic control group whereas the other 5 groups (6 rats per group) of diabetic rats were fed fermented camel milk (FCM) or fermented camel milk fortified with 1 and 1.5% of sage or mint leaves powder. Interestingly, the oral administration of fermented camel milk fortified with sage or mint leaves powder, at both concentrations, caused a significant decrease in blood glucose level and lipid profile, and an increase in insulin level compared to the diabetic control and FCM groups. Among others, the best results were observed in the group of animals that received fermented camel milk fortified with 1.5% sage powder. In addition, the results revealed that the fermented camel milk fortified with sage or mint leaves powder improved the liver and kidney functions of diabetic rats. Our study concluded that the use of sage and mint leaves powder (at a ratio of 1.5%) with fermented camel milk produces functional food products with anti-diabetic activity.Researchers Supporting Project, King Saud University, Riyadh, Saudi Arabia

Physical inactivity and its associated factors among adults in Malaysia : findings from National Health and Morbidity Survey (NHMS) 2019
Physical inactivity has been identified as the fourth leading risk factor for worldwide mortality with major implications towards general health. Monitoring the level of physical inactivity may reduce the burden of non-communicable diseases (NCDs) and their risk factors. This study aims to determine the prevalence of physical inactivity and its associated factors among adults aged 18 years and above in Malaysia.
Data was obtained from the National Health and Morbidity Survey (NHMS) 2019. It was a cross-sectional, population-based survey which employed two- stage stratified random sampling design. A total of 10,356 out of 10,472 respondents were interviewed using a short version of International Physical Activity Questionnaire (IPAQ).
Overall, the prevalence of physical inactivity among adults aged 18 years and above in Malaysia was 24.6% (95% CI: 23.2, 26.1). Results from multivariable logistic model showed that Chinese ethnicity (aOR 1.32; 95% CI: 1.04, 1.67), urban dwellers (aOR 1.30; 95% CI: 1.07, 1.57), those who were single (including widow, widower and divorcee) (aOR 1.36; 95% CI: 1.14, 1.61), students (aOR 2.10; 95% CI: 1.30, 3.40), higher household income earners (aOR 1.34; 95% CI: 1.07, 1.68) and those with hypercholesterolaemia (aOR 1.25; 95% CI: 1.03, 1.51) were significantly more likely to be physically inactive.
Specific and appropriate intervention towards targeted group is in crucial need to increase the level of physical activity and to promote an active living towards an active and healthy Malaysia
Anxiety and its associated factors among school-going adolescents in Malaysia
Many mental health disorders have onset during adolescence. To date, the data
on the correlates of anxiety is still lacking. Therefore, this study is crucial to
determine the factors associated with anxiety among school-going adolescents
in Malaysia.
Methods This study was based on 26,892 school-going adolescents from 212 selected
schools in Malaysia. Anxiety was measured using Depression Anxiety and
Stress Scale (DASS-21). Associations between anxiety, sociodemographic
characteristics and variables of interest were examined using multivariable
logistic regression.
Results Overall, 10,540 (39.7%) school-going adolescents had anxiety. Anxiety was
positively associated with female (odds ratio, OR [95% confidence interval,
CI] = 1.30 [1.19,1.42]) compared to male counterpart, feeling loneliness (1.78
[1.54,2.05]) compared to not lonely, unable to sleep due to worry of something
(1.79 [1.56,2.05]) compared to able to sleep, being bullied (1.66 [1.48,1.87])
compared to not being bullied, physical abuse (1.33 [1.18,1.49]) compared to
no physical abuse, verbal abuse (1.47 [1.35,1.59]) compared to no verbal
abuse, current drinker (1.23 [1.06,1.43]) compared to not current drinker,
current drug use (1.84 [1.43,2.35]) compared to not current drug use, ever had
sex (1.17 [1.01,1.36]) compared to never had sex, physically inactive (1.16
[1.06,1.26]) compared to physically active and internet addiction (2.59
[2.37,2.83]) compared to no internet addiction. Chinese ethnic (0.68
[0.50,0.93]) compared to other ethnic, and Form 2 (0.78 [0.69,0.89]) and Form
3 (0.73 [0.65,0.82]) students compared to Form 1 students, were protective of
anxiety.
Conclusions Prevention and intervention programs for these âat-riskâ adolescents should be
planned holistically towards reducing the risk factors
Evaluation of glycoproteins purified from adult and larval camel ticks (Hyalomma dromedarii) as a candidate vaccine
In order to identify antigens that can help prevent camel tick infestations, three major glycoproteins (GLPs) about 97, 66 and 40 kDa in size were purified from adult and larval Egyptian ticks, Hyalomma (H.) dromedarii, using a single-step purification method with Con-A sepharose. The purified GLPs were evaluated as vaccines against camel tick infestation in rabbits. The rabbits received three intramuscular inoculations of GLPs (20 ”g/animal) on days 0, 14, and 28. In the immunoblot analysis, Sera from the immunized rabbits recognized the native GLPs and other proteins from larval and adult H. dromedarii ticks along with those from other tick species such as Rhipicephalus sanguineus but not Ornithodoros moubata. The effects of immunity induced by these GLPs were determined by exposing rabbits to adult H. dromedarii ticks. These results demonstrated that GLP immunization led to a slightly decreased reproductive index and significantly reduced rates of egg hatchability. These results demonstrated that immunization with the purified GLPs can provide protection against infestation by H. dromedarii and some other tick species. Further studies are needed to confirm the effectiveness of immunization with GLPs against other tick species
