INFLUENCE OF COMBINED OSMOTIC DEHYDRATION AND AIR DRYING ON THE QUALITY OF GUAVA SLICES

This study was carried out to investigate the effect of osmotic dehydration on moisture content of guava slices during osmosis, the weight losses, solid gain and moisture losses parameters. Then the effect of the physical, chemical, microbiological characteristics and sensory attributes of the dried and osmo air dried guava slices were evaluated. The results showed that moisture content of guava slices was highly decreased in the first two hours during immersion in different osmotic solution regardless with and without the addition of calcium chloride. The results indicated that osmosis increased weight losses, solids gain and water losses from 29.7 -43.48% of the initial weight, 16.19 -18.66% of the initial solid and 46.34 -62.46% of the initial water in osmotically dehydrated guava slices, respectively. The results indicated that total sugar, ascorbic acid and phenolic contents of osmo air– dried guava slices were higher than that of air dried guava slices. The results showed that drying ratio of the osmosed samples ranged from 2.63:1 to 2. 86:1 regardless with and without addition of calcium chloride, while drying ratio of air dried guava slices without osmosis (the control) was 6.52:1. The results illustrated that overall acceptability scores of osmo air-dried prepared with sucrose solution or sucrose: fructose solution and sucrose: glucose at a ratio 1: 1(wt:wt) with adding calcium chloride were highly significant followed the same treatments without adding calcium chloride.
The Advantage Analysis of 3-D Inversion of Airborne Gravity Gradiometry Data With Larger Sampling Interval

Airborne gravity gradiometry is an effective tool for its high efficiency and sensitivity to the interesting buried targets, which has been increasingly introduced in mineral and petroleum exploration. When compared to gravimetry, full tensor gradient (FTG) measurements provide higher resolution and signal-to-noise ratio. In this article, we build and test models with different sampling intervals and compare the performances of individual components or their combinations in minimum structure inversion to evaluate the benefits of FTG combinations. As part of a theoretical study, the singular value spectrum (SVS) and depth-resolution plot (DRP) are examined to determine how much information and resolution different datasets provide in the underdetermined inverse problem. The synthetic examples show that integrating more components in inversion improves the resolution of the recovered model, and the inversion result of gravity or individual component cannot accurately restore the distribution of anomalous bodies. With the increasing sampling interval, joint inversion of FTG data still provides enough information corresponding to the source density distribution, and the limit survey interval is tested through models. In addition, we use a real survey over the Vinton dome as a case study and discover that $V_{\mathrm {zz}}$ component fails to reconstruct the caprock model at coarse line spacing, whereas FTG combinations recover the acceptable geometry flawlessly. It also reflects the benefit of FTG combinations for inversion processing, which reduces the interference of measured noise on inversion results and allows for longer sampling intervals during the survey, effectively lowering the cost of an airborne survey and improving exploration efficiency
MATHEMATICAL MODELING OF BLDC MOTOR WITH CLOSED LOOP SPEED CONTROL USING PID CONTROLLER UNDER VARIOUS LOADING CONDITIONS

In the recent past, variable speed driving systems have sprouted in various small scale and large scale applications like automobile industries, domestic appliances etc. The usage of green and eco friendly electronics are greatly developed to save the energy consumption of various devices. This lead to the development in Brushless DC motor (BLDCM). The usage of BLDCM enhances various performance factors ranging from higher efficiency, higher torque in low-speed range, high power density, low maintenance and less noise than other motors. The BLDCM can act as an alternative for traditional motors like induction and switched reluctance motors. In this paper we present a mathematical model of BLDC motor and show the values of various technical parameters using MATLAB/SIMULINK. In this paper the simulation is carried out for 120 degree mode of operation. The test results show the performance of BLDCM which are highly acceptable. Finally a PID controller is applied for closed loop speed control under various loading conditions.
FACTORS AFFECT PERFORMANCE MEASUREMENT IN CONSTRUCTION PROJECT PORTFOLIO

Construction companies regularly perform multiple construction projects concurrently. Projects vary by complexity, duration, budget, variety of works, and the number of stakeholders. To determine and report the status of the ongoing portfolio of projects, methodical agreed-upon metrics should be set forth at both projects and portfolio level. The assessment of project indicators during implementation is not an easy task due to the lack of up-to-date data and factors measuring problems. The purpose of the research is to analyze common performance measurement factors, the contribution of those factors to the overall project portfolio performance, and to illustrate how to assess a projects' execution efficiency. A review for the earlier research and studies has been done to name the commonly used factors usually picked to measure the performance of portfolio and project management efficiency. A questionnaire survey conducted to project management professionals exploring their judgment in respect of relative weight contribution to each factor. AHP mathematical model used to analyses the survey responses.
A Meta-Analysis of the Distinct Effects of Neurofeedback (Particularly TBR) on Inattention and Hyperactivity

This meta-analytical study examined the effect of neurofeedback on reducing both the (a) inattentive and (b) hyperactive / impulsive components of children diagnosed with Attention- eficit / Hyperactivity Disorder (ADHD). The main finding of the meta-analysis was that theta-beta ratio training achieved identical, statistically significant, and practically large effects on both inattention (g = 0.92) and hyperactivity / impulsivity (g = 0.77). An analysis of the literature indicates that the effectiveness of theta-beta ratio-based neurofeedback appears to derive from a general, top-down effect applicable in the frontal regions of the brain, particularly areas and structures related to information processing. One recommendation emerging from the meta-analysis is for neurofeedback practitioners and researchers to better document details related to site placement and bandwidths in order to identify better protocols based on theta-beta ratios. In addition, the importance of alpha generation was highlighted as a means of going beyond static theta-beta ratios in both the diagnosis of ADHD and the measurement of neurofeedback protocol success over time.
Physical Therapy Student Stress During the COVID-19 Pandemic: A Qualitative Study

Supplemental Digital Content is Available in the Text. Introduction. According to research studies and surveys conducted by the Centers for Disease Control and Prevention, the prevalence of stress, depression, and anxiety have increased with the onset of the COVID-19 pandemic. This is especially true for young adults and has the potential to affect students’ learning outcomes and long-term well-being. Review of Literature. Current research on the experience of stress for students in the health professions has focused on nursing and medical students. There are no published studies exploring pandemic-related stress in physical therapy. The purpose of this study was to explore the experience of stress for Doctor of Physical Therapy (DPT) students during the onset of the COVID-19 pandemic. Subjects. Twenty-four students in their first, second, and third year of study from 3 physical therapist education programs. Methods. Using a phenomenological qualitative approach, 60-minute semi-structured interviews were conducted with each participant through video conference in April and May of 2020. Inductive thematic analysis was used to identify and refine codes and construct themes and subthemes. Results. Four themes resulted from analyses of these data: sources of stress, stress management, stress modifiers, and positive aspects of COVID. Sources of stress were related to academics, uncertainty, personal circumstances, and finances. DPT students described stress associated with the transition to online learning related to focus, engagement, workload, and reduced opportunities to practice hands-on skills. Uncertainty was particularly stressful for third-year students who were anxious about clinical experiences, board examinations, and future employment. Stress management strategies were centered on cognitive reappraisal, physical activity, and social support. Discussion and Conclusion. While students identified several sources of stress during the onset of the COVID 19 pandemic, important stress modifiers, such as faculty and cohort-based peer support, were highlighted that have the potential to reduce stress for students both in times of crisis and under more typical circumstances. These factors, in combination with findings suggesting that increased flexibility and agency over learning mediated stress responses, have potential implications for instructional delivery and academic program design.
Factors Associated With Repeat Emergency Department Visits for Low Back Pain

Background Low back pain represents 2-3% of Emergency Department (ED) visits. In this study, we aimed to identify patient and treatment-related variables that contributed to repeat visits to the ED for low back pain within a 12-month period. Methodology We conducted a retrospective review of adult patients presenting to the ED of one hospital over a two-year period with the primary diagnosis of low back pain. The primary outcome included return to the ED within 12 months with the same complaint, and the secondary outcome included return to the ED within 30 days or six months. Results A total of 793 patients met the inclusion criteria. The rate of return to the ED with the same complaint within 30 days, six months, and 12 months of the first visit was 7%, 11%, and 14%, respectively. Patients who received opioids at discharge were more likely to return within 12 months (68% vs. 55%; p = 0.0075) and six months (68% vs. 56%; p = 0.0184) compared to those who did not receive opioids at discharge. Undergoing an X-ray decreased the odds of a 30-day return visit by 70% (p = 0.0067), and by 59% within 12 months (p = 0.0032). Receiving opioids at discharge also doubled the odds of return within 12 months (odds ratio = 2.030, p = 0.0183), while receiving nonsteroidal anti-inflammatory drugs (NSAIDs) reduced the odds by 60% (p = 0.0028). Conclusions Patients who received opioids at discharge were more likely to have a return visit for low back pain within six and 12 months. Patients who underwent X-rays at the index visit and were prescribed NSAIDs at discharge were less likely to return to the ED for low back pain.
Effect of Helicobacter Pylori Infection on Nutrition, Metabolism, Cognition, and Serum Vitamin B12 in the Elderly

Background: Helicobacter pylori infection is one of the most common infections in humans. The rate of H. pylori infection and its complications is increasing with age worldwide. Many articles have published on the fascinating topic of extra-gastroduodenal manifestations of H. pylori infection, most of which are commonly seen in the elderly population. Aim: To investigate the effect of H. pylori infection on nutrition, metabolism, cognition, and serum vitamin B12 in the elderly. Subjects and Methods: This study was conducted on 30 elderly patients with H. pylori infection diagnosed by stool antigen test and 30 healthy control subjects matched for age, sex and socioeconomic status. Full history, complete physical examination, anthropometric measurements, laboratory parameters (routine laboratory investigation, metabolic parameters, serum iron level, serum vitamin B12 level), and HOMA-IR score. Moreover, all participants completed the mini mental state examination (MMSE) and mini nutritional assessment (MNA) questionnaires. Results: the results showed that patients with H. pylori infection had significantly lower hemoglobin levels, lower serum iron levels, lower vitamin B12 levels, higher insulin levels, and higher prevalence of insulin resistance (defined as a HOMA-IR score ≥2.5). There were no significant differences between the groups regarding the mean MMSE score, the mean MNA score, or the prevalence of metabolic syndrome according to the definition of the National Cholesterol Education Program Adult Treatment Panel III. Conclusion: H. pylori seems to be associated with iron deficiency anemia, vitamin 12 deficiency and insulin resistance in the elderly.
3-D FEM inversion for the in-situ stress field around complex faults based on the theory of constrained optimization

According to the distribution characteristics of in-situ stresses measured in the fault-block G around complex faults,in-situ stress field is simulated and estimated by establishing numerical model suitable for geological structure of the block G and applying the COFEM method(constrained optimization finite element method) based on the FEM method and the theory of constrained optimization. Simulating results fit with the distribution characteristics of the measurements. In addition,the influence of complex faults on regional in-situ stresses is analyzed by comparing the in-situ measurements with numerical results. It is shown that the distribution of in-situ stresses around faults is mainly affected by its near faults,and depends mainly on the scale of the fault and the distance from the near fault. Because of the influence of the faults,the distribution of in-situ stresses around faults is complicated,especially the terminal portion of faults,the distribution of in-situ stresses field can not be generated by some discrete measuring points. Three-dimensional numerical simulation is very important for us to analyze and estimate the in-situ stresses field.
Effects of regulated dry season irrigation on tree water use, root zone moisture dynamics and yield of cacao in a rainforest zone of Nigeria

A field trial was conducted to investigate the effects of regulated dry season irrigation on tree water use, root zone moisture dynamics and yield of cacao in a rainforest zone of Nigeria. Following cessation of rainfall in November, irrigation commenced from December 2017 to May 2018. Irrigation amount was computed based on cumulative class A Pan evaporation. Irrigation treatments were coded as IrT1, IrT2 and IrT3, consisting of water application using EPan *Pan coefficients (Kcp) of 1.0; 0.70 and 0.50 (9.6, 6.8 and 4.8 l/tree/day). Irrigation water applied at 5-days interval was discharged via point source emitters (2.8 l/h discharge rate ) on drip lines laterally installed per row of trees. Irrigation requirements were on the average, 4.49, 3.14 and 2.44 mm, total water applied per irrigation events were 1009.88, 706.92 and 504.94 mm per plot ( 225 m2 ), total seasonal water applied were 33858, 23701 and 16929 mm, and soil moisture contents were 52, 45 and 28% for the respective IrT1, IrT2 and IrT3. Tree evapotranspiration (ETc) were 4.54, 3.19 and 2.32 mm/day while seasonal sums were 809, 566 and 404 mm while the ratio of ETc to EPan were 0.9, 0.69 and 0.53 for IrT1, IrT2 and IrT3. Tree water use efficiencies were 0.3 and 0.04 t/mm for Y/ETc and 0.16 to 0.19 kg/mm for Y/Irrigation respectively. Cacao pod and bean yields were 35.4, 22.1 and 10.3 t/ha and 2.29, 1.37 and 1.03 t/ha while yields decreased by 60 and 40% under IrT3 and IrT2 compared with IrT1. The study identified suitable Pan coefficients for scheduling irrigation during the dry season for cacao, full irrigation (EPan*1.0) applied at 9.6 l/tree/day will be needed to replenish soil water depletion to satisfy crop consumptive water use ( transpiration and soil evaporation components). The low pressure gravity-drip irrigation system alleviated climate stress during the dry season and improved cacao performance in a tropical rainforest environment.
Surge current distribution in a reinforced concrete structure during building struck by lightning

When a lightning strikes directly to a building, large impulse currents flow through various conducting branches of the building's protection structure, then electromagnetic disturbance is caused within the building. An efficient method was reviewed in this paper to calculate surge current distribution in a reinforced concrete structure during building struck by lightning. The electric parameters of conducting branches were represented in capacitance and impedance mode, the capacitance parameters were calculated by means of average potential method, while the impedance parameters were evaluated by Neumann's formula. Based on electric parameters, the conducting system was converted to an equivalent network constituted for a series of coupled π type circuits. The network was analyzed by electromagnetic transient program (EMTP), and the surge current distribution was presented. Some comparison tests were conducted in high voltage laboratory of Tsinghua University, and the computation is in coincidence with the test.
A Subject-Tailored Variability-Based Platform for Overcoming the Plateau Effect in Sports Training: A Narrative Review

The plateau effect in training is a significant obstacle for professional athletes and average subjects. It evolves from both the muscle-nerve-axis-associated performance and various cardiorespiratory parameters. Compensatory adaptation mechanisms contribute to a lack of continuous improvement with most exercise regimens. Attempts to overcome this plateau in exercise have been only partially successful, and it remains a significant unmet need in both healthy subjects and those suffering from chronic neuromuscular, cardiopulmonary, and metabolic diseases. Variability patterns characterize many biological processes, from cellular to organ levels. The present review discusses the significant obstacles in overcoming the plateau in training and establishes a platform to implement subject-tailored variability patterns to prevent and overcome this plateau in muscle and cardiorespiratory performance.
How Transformational Leadership Motivates Employee Involvement: The Roles of Psychological Safety and Traditionality

This study aims to explore how transformational leadership affects employee job involvement. Using the cross-sectional survey method, a questionnaire survey was conducted among 205 teachers in 15 universities located in Southern China. Hierarchical regression and bootstrapping technique were combined to test the hypothesis. The results reveal that psychological safety mediates the link between transformational leadership and job involvement. Moreover, the traditionality of university teachers strengthens the effect of psychological safety on job involvement. This study expands job involvement literature by examining the integrative effects of multiple resources, and all resources are aligned to extend the pool of resources owned by university teachers. These findings also bring some enlightenment on how to motivate university teachers to engage actively in their work.
MANAGEMENT STRATEGIES FOR HERBICIDE-RESISTANT WEEDS BY USING DIFFERENT HERBICIDES IN SEQUENTIAL APPLICATION FOR EFFECTIVE AND SAFE WEED CONTROL IN WHEAT.

Three field experiments were carried out during the successive winter seasons on 2017/2018 and 2018/2019 at Sids Agricultural Research Station farm, A.R. C. , Bani Swif Governorate, Egypt, to management resistance development by using herbicides with different sites of action (SOA's) in the sequential application at reduced rates with adjuvants (mineral oil) on productivity, quality and associated weeds of wheat (Triticum aestivum L.). Experiment No.1 studied the efficacy of certain graminicide Topic 15% WP (clodinafop propargyl), Eferst 70% WG (flucarbazone sodium), both used at full rate, alone, and in sequence at reduced rate with mineral oil 1%, Experiment No.2 studied controlling broad leaved weeds herbicides Garenary 75% WG (tribenuron-methyl), Brominal 24 % EC (bromoxynil-octanoate), both used at full rate, alone, and in sequence at reduced rate with mineral oil 1% and Experiment 3: studied controlling grassy and broad-leaved weeds used herbicides Otheilo OD 5.25% OD (diflufenican 5%+ iodosulfuron methyl sodium 0.25+ Mesosulfuron methyl 0.75%) a ready formulated at full rate, alone, and the sequential application (Topic, Eferst, Garenary and Brominal) at reduced rates with mineral oil. All experiments included hand weeding at 20 and 40 days after sowing and weedy check. Each experiment was laid out in a Randomized Complete Blocks Design with four replicates. Results of Exp.No.1 indicated that the sequential application of herbicides at reduced rate Eferest (10 g/fed.) followed by Topik (70 g/fed.) both with mineral oil (1%), gave more efficiency weed control than that obtained by each alone, whereas, the fresh weight of grassy weeds were (23.3 and 33.5 g/m 2 ) and grain yield (22.88 and 23.70 ardab/fed.) in the 1 st and the 2 nd seasons, respectively. Exp.2: Results showed that the sequential application of Gerenary (4 g/fed.) followed by brominal (500 cm 3 /fed.), both at reduced rate plus mineral oil at 1%, better decreasing fresh weight of broadleaved weeds by (29.0 and 34.0 g/m 2 ) as compared to other treatments with while, increasing on wheat yield (23.45 and 24.12 ardab/fed.) in both seasons, respectively. Results of Exp.No.3: showed that the maximum weed control efficiency was achieved with sequential application of Gernary in combination with Topik both at reduced rates with mineral oils (1%), whereas, gave decreasing total weeds fresh weight by (55.75 and 48.0 g/m 2 ) compared to the other treatments, similar trend was observed in grain yield of wheat and its components. Therefore, it could be concluded from this study that, to avoid the appearance of the development herbicide-resistant weeds should be chosen various herbicides with different site of action in sequence application at reduced rates with adjuvants (mineral oil) to achieve efficiency of weed control without loosing in wheat yield and its components.
Comparison of Data Mining Techniques for Predicting Compressive Strength of Environmentally Friendly Concrete

AbstractWith its growing emphasis on sustainability, the construction industry is increasingly interested in environmentally friendly concrete produced by using alternative and/or recycled waste materials. However, the wide application of such concrete is hindered by the lack of understanding of the impacts of these materials on concrete properties. This research investigates and compares the performance of nine data mining models in predicting the compressive strength of a new type of concrete containing three alternative materials as fly ash, Haydite lightweight aggregate, and portland limestone cement. These models include three advanced predictive models (multilayer perceptron, support vector machines, and Gaussian processes regression), four regression tree models (M5P, REPTree, M5-Rules, and decision stump), and two ensemble methods (additive regression and bagging) with each of the seven individual models used as the base classifier. The analytical results show that, with appropriate parameter sett.
