Gait Analysis Using the Physics Toolbox App

Sensors in new smartphones can be an excellent tool to measure different physical quantities and these can be useful to develop real experiments with application in human health. Therefore, in this research work, the design and construction of a gait analyser was carried out using the toolbox physics app for data acquisition and MATLAB was used for its analysis. This system analyses the behaviour of walking in people and its purpose is to diagnose any health problem caused by the human being’s way of walking. For this, the g-force meter was used in <inline-formula> <tex-math notation="LaTeX">$x$ </tex-math></inline-formula>, <inline-formula> <tex-math notation="LaTeX">$y$ </tex-math></inline-formula>, and <inline-formula> <tex-math notation="LaTeX">$z$ </tex-math></inline-formula> components. This application uses inputs from the device’s sensors to save and export the data in comma-separated values (CSV) format through a.csv extension. The results are very interesting because they can be used in medical diagnoses such as reduced gait speed and loss of regularity, symmetry, or synchronization of body movements. Since many organs are involved in gait, there are several types of gait disturbances that cause gait to be abnormal. With this system, it is possible to identify the hemiplegic gait, festinating gait, paraparhetic gait, waddling gait, among others. This analysis was carried out using the Pearson, Spearman, and Kendall correlation coefficients, which indicate the possible diagnoses in the patients.
Influence of Maternal Education on Second Childbirth Interval Among Women in South Africa: Rural-Urban Differential Using Survival Analysis

Inter-birth interval lengthening is a key component of fertility decline. Although South Africa fertility rate remains the lowest in sub-Saharan Africa, information on the effect of education on the interval between first- and second-birth across residential contexts is rarely documented. The study investigated the relationship between maternal education and second-birth interval (SbI) by residence among South African women. The study analyzed the 2016 South Africa Demographic and Health Survey data on 6,039 women aged 15 to 49 years who had reported at least one childbirth at the time of survey. Survival analysis methods were applied at 5% significance level. The SbI was significantly longer (p < 0.001) among urban (76 months) relative to rural (66 months) women. About a fifth of rural women and about a tenth of urban women had at most a primary education. Women who had a secondary education (aHR = 0.86; 95% CI [0.76, 0.96]) were 14% times more likely to delay second-birth compared to those who had at most a primary education in rural setting. Other determinants of SbI included region in rural; age at-first-birth and household wealth in urban; ethnicity, marital status at-first-birth and employment in both residential settings. The length of SbI remains long in both residential contexts, but longer in urban. Findings demonstrated rural-urban differentials in the relationship between maternal education and second birth interval, suggesting contextual impact. Fertility strategies targeted at strengthening health education for improved maternal and child health should be residential-context specific.
Gossypin attenuates methotrexate-induced nephrotoxicity: Role of COX II/MMP-9 and fas ligand.

Methotrexate (MTX) is one of commonly used chemotherapeutic drugs, with well-known nephrotoxic effect. This study aimed to investigate the protective mechanisms of gossypin; a bioflavonoid present in plants, against MTX-induced nephrotoxicity. Rats were allocated into 4 groups: control, gossypin, MTX, and gossypin/MTX groups. Evaluation of renal function and histological images were done. Renal tissue oxidative markers of lipid peroxidation, total nitrite/nitrate (NO) level, reduced glutathione (GSH) and superoxide dismutase (SOD) were measured. Inflammatory and apoptotic markers as matrix metalloproteinase-9 (MMP-9) and beta-cell lymphoma-2 (Bcl-2) mRNA and protein expressions, respectively, as well as renal immunohistochemical expression of cyclooxygenase-II (COX-II) and fas ligand, were assessed. Renal P-glycoprotein (P-gp) expression was also measured. MTX caused a significant elevation in kidney functions, with noticeable elevation in‎oxidative‎ stress‎markers’‎ levels,‎ as‎well‎ as‎COX-II and fas ligand expressions. Moreover, MTX decreased renal antioxidant enzymes, P-gp level, and Bcl-2 expression. Gossypin administration significantly improved renal functions and oxidative insults, in addition to significant improvement of inflammatory and apoptotic parameters. Gossypin administration before MTX also ameliorated renal damage, at least in part, via modulation of P-gp level. In conclusion, gossypin may be an effective nephroprotective adjuvant to MTX through antioxidant, anti-apoptotic, and anti-inflammatory mechanisms.
POTENTIAL USE OF SOME NATURAL MATERIALS FOR REMEDIATING POLLUTED WATER

In the light of water scarcity and high population growth of Egypt, there is an urgent need to exploit and reuse every drop of water. Remediation of the available marginal water resources such as drainage water for irrigation purposes became mandatory. A laboratory experiment was conducted at Soil Science Department Laboratory, Faculty of Agriculture, Zagazig University during 2021 to find effective and low-cost ways of wastewater remediation to be easily available. For that, the water samples were synthetically contaminated with two heavy metals, namely nickel and lead which were added in concentrations of 10 mg/l and 0.5 mg/l, respectively. Four natural materials i.e, moringa seeds cake (M), rice straw biochar (B), sugarcane bagasse biochar (S) and zeolite (Z) were used in this investigation to study their potentiality on removing lead and nickel from polluted water. All materials were used at two rates of 10 and 20g/l. Four different particle diameters were used for each of rice straw biochar, bagasse biochar and zeolite as follows: < 0.125 mm, 0.125 – 0.212 mm, 0.212 – 0.250 mm and > 0.250 mm. All materials used gave considerable efficiencies in removing lead and nickel ions from polluted water showing an inverse proportional efficiency with particle diameters. The rate of 20g/l surpassed the rate of 10 g/l for all treatments under the same diameter. The most efficient treatment for removing lead was sugarcane bagasse biochar at rate of 20 g/l and particles diameter less than 0.125 mm with a removal efficiency of 90.39 % whereas the most efficient treatment for removing nickel was rice straw biochar at rate of 20g/l and diameter of particles less than 0.125mm with removal efficiency of 81.6%. The removal efficiency of lead for the investigated natural materials could follow the order: sugarcane biochar> rice straw biochar> moringa seeds cake> zeolites while the order was rice straw biochar> sugarcane bagasse biochar> moringa seeds cake> zeolites for nickel.
Quantitative evaluation of pipe wall thinning defect sizes using microwave NDT

ABSTRACT This study investigated the applicability of microwave non-destructive testing, which has been proved effective in quickly detecting the defect location in a long pipe, to the size evaluation of wall thinning defects. Artificial wall thinning defects with different sizes (depths and lengths) and edge profiles were introduced to a flanged brass pipe with a total length of 15 m, and reflected microwave signals were measured in experiments. A signal processing method combining windowing and dispersion compensation was proposed to extract the defect-related reflection signals in the frequency domain. Resonant frequencies, at which the amplitude of extracted signals dropped significantly, decreased with the increase of either wall thinning depth or length. In addition, the results demonstrate that wall thinning location and pipe end conditions have little influence on resonant frequencies after signal processing. A back propagation neural network was trained by simulation data, using resonant frequencies as the input, to simultaneously evaluate defect depth and length, and the performance was validated by experiments. Maximum prediction errors of depth and length of wall thinning were 0.06 mm and 0.57 mm, respectively, which indicated the feasibility of the proposed method to evaluate the wall thinning defect sizes.
Teledermatology and Inflammatory Skin Conditions during COVID-19 Era: New Perspectives and Applications

Background: The most frequent inflammatory skin diseases are psoriasis, atopic dermatitis, hidradenitis suppurativa, and acne. Their management is challenging for dermatologists since their relapsing chronic clinical course is associated with a great impact on quality of life. Nevertheless, the recent introduction of novel therapies, such as biological drugs and small molecules has been changing the history of these diseases. Methods: A systematic review of the scientific literature of case reports, case series, epidemiological studies, reviews, and systematic reviews regarding teledermatology and inflammatory skin disease. Studies were identified, screened, and extracted for relevant data following the PRISMA (preferred reporting items for systematic reviews and meta-analyses) guidelines. Results: A total of 69 cases articles were included in the review. Conclusions: As we have shown in the review, several experiences of teledermatology for patients affected by inflammatory skin diseases have been demonstrated to increase due to clinical access to hospital and specialized health care services, allowing better access to specialized dermatology care for people living in remote areas, and saving costs and money with health care.
Effect of Soaking Process on Chemical Characteristics and Anti Nutritional Factors of some Moringa Seed Varieties

Moringa seeds have high medicinal and value nutritional. This is mainly to the large stock of biologically active ingredients in seeds. With the global shortage of food grains, the incidence of nutritional deficiency diseases and the ever-increasing population, Moringa in particular will certainly provide a good alternative to make up for the food shortage. This research aimed to study the effect of soaking process in water and in NaOH 0.5% solution on the Moringa seeds. Gross chemical composition, minerals, anti nutritional and fatty acid of M. oleifera and peregrina seeds were investigated. In general, Soaking has a significant (p <0.05) effect on the gross chemical of M. oleifera M. peregrina seeds. There is a large variation in minerals value both of raw and soaked Moringa oleifera and Moringa peregrina kernels. Results revealed that crude extract obtained from both of raw Moringa (oleifera and peregrina) seeds showed that there was a significant difference in anti-nutritional content before and after soaking. The aqueous soaking treatment was more effective than soaking with alkali solution NaOH 0.5% to remove anti nutritional factors. Furthermore, fatty acid oleic (C18:1) represented the highest proportion of fatty acids. Results indicated that soaking processes caused a significant decrease in total unsaturated fatty acids content, accompanied by an apparent increase in the total saturated fatty acids of M. oleifera and Peregrina seeds.
Effect of Conventional Nursing Combined with Bedtime Oculomotor Training on Sleep Quality and Body Immunity of Advanced Lung Cancer Patients

Objective The aim of this study is to explore the effect of conventional nursing combined with bedtime oculomotor training on sleep quality and body immune of advanced lung cancer patients. Methods By means of a retrospective study, 120 advanced lung cancer patients admitted to our hospital from January 2019 to January 2020 were selected as the research subject and divided into the intervention group (PSQI (Pittsburgh Sleep Quality Index) score≥10 points, n = 60) and the control group (PSQI score<10 points, n = 60). Conventional nursing was performed to the control group, and an eye movement exercise before sleep was added additionally in the intervention group, 30 min each time, once a day, and 5 times a week for 3 months, so as to compare their sleep quality, body immunity indexes, negative emotion scores, adverse reaction rate (ARR), quality of life, and satisfaction with nursing. Results After nursing, the intervention group obtained a significantly lower PSQI score (5.54 ± 1.23 VS 7.98 ± 1.65, P < 0.05), better body immunity indexes (P < 0.001), lower negative emotion scores (P < 0.05), lower ARR (P < 0.05), better quality of life (P < 0.001), and higher satisfaction with nursing (P < 0.05) than the control group. Conclusion Combining conventional nursing with the eye movement exercise before sleep can alleviate negative emotions, improve the sleep quality, promote body immunity, and reduce the ARR, which is more satisfying to patients and should be applied and promoted in practice.

Laparoscopic Cholecystectomy Using Harmonic Scalpel Versus Conventional Laparoscopic Cholecystectomy

Background: laparoscopic cholecystectomy is the worldwide gold standard treatment of symptomatic gallbladder lithiasis. During the conventional LC, we used usually clips for closure of cystic duct and artery and dissector, electrosurgical hook, spatula and/or scissor for dissection of cystic duct and artery and sealing of gall bladder from liver bed. Now, single instrument called harmonic scalpel is introduced as a potential replacement for all of these instruments. Objective: To evaluate the safety, efficacy and clinical outcome of LC using harmonic scalpel compared with conventional LC. Patients and Methods: Our prospective randomized study was carried out during the period from February 2018 to August 2018 at Azhar Assuit University Hospital, and included 60 adult patients presented with chronic calcular cholecystitis divided randomly into 2 groups. All patients of both groups were signed the informed consent and assessed preoperative (history, clinical examination, CBC, LFTs, RFTs, virology and Pelviabdominal ultrasound), intraoperative (time, incidence of gall bladder perforation, bleeding and conversion to open procedure) and postoperative (pain, analgesia, drain, bile leakage, hospital stay and wound infection). Results: No statistically significant difference was found age, sex, BMI and associated diseases between both groups but there is significant difference in operative time, incidence of gall bladder perforation, blood loss, postoperative pain, drain and hospital stay. No significant difference in wound infection. No incidence of bile leakage or conversion to open procedure in both groups. Conclusion: Harmonic scalpel in general is an efficient tool for complete hemobiliary sealing with high safety profile.
Effect of Replacing Berseem Hay by Dried Sugar Beet Tops on Performance of Friesian Calves

The current work was carried out to investigate the effect of replace different percentages of berseem hay (BH) by dried sugar beet tops (DSBT) on the performance of suckling and post weaning Friesian calves. Twenty newly born Friesian calves (10 males and 10 females) with live body weight (LBW) of 41.3±0.5 kg were used after suckling their dam’s until 15 days of age, and then divided into five similar groups. The whole experimental period was lasted for 165 days where it staged for consecutive two periods, the first one (P1) was serves as suckling period from the 15 days of age until the weaning and the second one (P2) was continued from 106 to 180 days of age (post weaning period). All claves were fed a basal diet consisted of whole milk, calf starter (CS), BH and DSBT during P1. Consecutively, CS, BH and DSBT during P2. Calves were assigned randomly on the following treatment groups, G1: 50% CS + 50% BH, G2: 50% CS + 37.5% BH + 12.5% DSBT, G3: 50% CS + 25% BH + 25% DSBT, G4: 50% CS + 12.5% BH + 37.5% DSBT and G5: 50% CS + 50% DSBT. Results showed that replace of BH by DSBT improved (P<0.05) the digestibility coefficients of DM, OM, CP, CF, EE and NFE as well as nutritive values represented as TDN and DCP during the different experimental periods, where, the G3showed the highest (P<0.05) values. Also, ruminal pH value and ammonia-N were decreased (P<0.05) with G3, however, TVFA’s was increased (P<0.05). But, there were no differences among G1 and G2 or G4 and G5. Moreover, the effect of replace of BH by DSBT on plasma total protein, albumin, creatinine, urea-N, liver enzymes (AST and ALT) activity, Cholesterol, Triglycerides and glucose of Friesian calves during different experimental periods were improved with G3 and G2. The values which obtained in this study are with the normal range. Calves in G3 recorded the highest LBW, WG and ADG followed by calves in G2, G1, G4 and G5 during the different periods. Also, G3 and G2 showed the highest total and net revenue compared to other groups. It could be concluded that there place 50% of BH by DSBT (G3) for Friesian calves rations improved the Friesian calves performance and economic efficiency.
A note on the hot days of Madras (1875-1963)

The incidence of heat waves over the city of Madras during the summer months March to June for the period 1875-1963 has been studied in this note. Delay in the onset of sea breeze by 2 to 3 hours, advective transfer of hot continental air from the Deccan plateau and warming by adiabatic descent of the prevailing northwesterly or westerly winds down the sloping terrain are shown to be the principal factors contributing to the occurrence of such hot spells over Madras.
Proportional and Integral Variable Structure Controller (PI –VSC) for Grid Connected PWM Voltage Source Converter

This paper introduces an improved method for DC link voltage regulation in pulse width modulation rectifier (PWMR) applications. The mathematical model of PWMR in synchronous reference frame is introduced. This model is used to investigate and design of DC voltage and current control loops. The current controller is designed based on modulus optimum, magnitude optimum, (MO) criteria while the voltage controller is designed based on Proportional Integral (PI) with variable structure control (VSC) concept, which is denoted as PI-VSC. In PI-VSC, the control system switches between PI and pure I controllers according to pre-defined switching function. The PI-VSC has three tuning parameters, which are the PI-controllers gains and the switching function. The PI controller gains are tuned using Symmetrical Optimum (SO) criterion, while the switching function based on the absolute error signal. To verify the validity
The Path to Hedonic Information System Use Addiction: A Process Model in the Context of Social Networking Sites

Addiction to hedonic information systems yields significant negative consequences for users. Although we know about the causes of addictions, particularly those related to individual differences, recent evidence suggests that addiction evolves gradually over time and is rooted in shared characteristics of users and technology. This paper provides a longitudinal perspective over how and why hedonic information systems (IS) use addiction develops. Based on our analysis, we break down this process into three phases characterized by different types of use, whether nominal, compulsive, or addicted. Each phase highlights salient psychological needs that motivate, technology features that enable, and affordances that are actualized into each type of use. We also provide a detailed account of individuals’ self-control mechanisms, explaining how deficiencies in sensing, comparing, or regulating behavior facilitate one’s transition toward addiction. These insights are applicable to other hedonic IS that are similar in terms of ubiquity and constant access through mobile apps. They point to heterogeneous (preventive or intervening) strategies that can be used to help people regain their control over use, depending on where they are in their trajectory toward addicted use. Our findings carry implications for the design of systems and features that can help reduce the likelihood of addiction development.
Effect of Zirconium Oxide Nano-Fillers on Dimensional Accuracy of Acrylic Resin Maxillary Complete Dentures: An in vitro study

Introduction: Addition of nanofillers to the denture base material in order to enhance its mechanical properties may contribute to the dimensional accuracy of the processed dentures. Aim: This study was conducted to investigate the effect of zirconium oxide nanofillers addition on the dimensional accuracy of maxillary heat cured acrylic dentures. Materials and Methods: Thirty six identical maxillary waxed up dentures were constructed, divided into two equal groups(n=18), control group processed into conventional heat cured acrylic resin dentures and test group processed into 5% zirconium oxide nanofiller reinforced heat cured acrylic resin dentures. Teeth movements were estimated linearly using digital software after processing and vertically using digital caliper before and after processing. Changes in denture adaptation were measured immediately after processing and after seven days hydration in distilled water using digital software. Results: After processing, both groups showed increased Vertical dimension of occlusion with less increase with the test group. Both groups showed changes in teeth position with non-significant difference. Test group showed more tendency to inward tooth movement. Test group showed significant more denture adaptation after processing. However, denture hydration caused decrease in denture adaptation in the test group while causing enhancement in denture adaptation with the control group. Conclusion: Zirconium oxide nanofillers reinforcement showed nearly comparable results of dimensional accuracy to the conventional dentures with negative results on hydration.
