Relationship between problematic Internet use, body mass index and psychiatric morbidities in Egyptian high school adolescent students

Background: Problematic internet use (PIU) is an emergent universal problem amongst students. The problem is growing in Egypt with the progressively mounting internet usage. Also, overweight of adolescents remains serious and alarming national and international health problem. Objective: To study the prevalence and coincidence of PIU, obesity and psychiatric disorders amongst students in governmental Egyptian high schools. Subjects and Methods: A cross sectional study was performed on randomly chosen 828 students from 2 governmental high schools in urban Gamalia town - Dakahlia governorate – Egypt. Students were classified into theoretical educational group and scientific educational group. the students in each group were requested to fill Young Internet Addiction Test (YIAT) and General Health Questionnaire (GHQ-12) to assess problematic internet use and presence of psychiatric morbidity. Prior to that, sociodemographic data, medical reports and anthropometric measurements of the students had been obtained. Results: We noted that 12% (100 students) of the study candidates were obese, 24.3% (201 students) were overweight and 63.7% (527 students) represent normal and underweight adolescents. As well, it was found that 13.2 % (109 students) of the students were problematic internet users (PIUs). Prevalence of PIU was found higher among young ages, males and obese students. Also, students with higher father’s educational degree, those who frequently use internet and those using internet for relieving loneliness, had a higher prevalence of PIU. Impaired relation with classmate friends with poor parents’ satisfaction were also found in PIUs. The result also revealed that 31.9% of the total students suffering from distress and 6.1% having severe problem and psychological distress. Also, our results showed that the PIU and psychological distress had a highly significant positive correlation [r (p-value) = 0.975 (<0.001)]. Similarly, a highly significant positive correlation was observed between PIU and body mass index (BMI) [r (p-value) = 0.914 (<0.001)]. Furthermore, a highly significant positive correlation was found between psychological distress and BMI [r (p-value) = 0.881 (<0.001)]. Conclusion: Problematic internet use and obesity are common and -associate each other- among high school students in Egypt which may affect their psychological health.
RELATIVE PRODUCTIVITY, PROFITABILITY AND WATER USE EFFICIENCY OF CROPPING SYSTEMS IN HOT ARID INDIA

SUMMARY The choice of an appropriate cropping system is critical to maintaining or enhancing agricultural sustainability. Yield, profitability and water use efficiency are important factors for determining suitability of cropping systems in hot arid region. In a two-year field experiment (2009/10–2010/11) on loam sandy soils of Bikaner, India, the production potential, profitability and water use efficiency (WUE) of five cropping systems (groundnut–wheat, groundnut–isabgol, groundnut–chickpea, cluster bean–wheat and mung bean–wheat) each at six nutrient application rate (NAR) i.e. 0, 25, 50, 75, 100% recommended dose of N and P (NP) and 100% NP + S were evaluated. The cropping systems varied significantly in terms of productivity, profitability and WUEs. Averaged across nutrient application regimes, groundnut–wheat rotation gave 300–1620 kg ha−1 and 957–3365 kg ha−1 higher grain and biomass yields, respectively, than other cropping systems. The mean annual net returns were highest for the mung bean–wheat system, which returned 32–57% higher net return than other cropping systems. The mung bean–wheat and cluster bean–wheat systems had higher WUE in terms of yields than other cropping systems. The mung bean–wheat system recorded 35–63% higher WUE in monetary terms compared with other systems. Nutrients application improved yields, profit and WUEs of cropping systems. Averaged across years and cropping systems, the application of 100% NP improved grain yields, returns and WUE by 1.7, 3.9 and 1.6 times than no application of nutrients. The results suggest that the profitability and WUEs of crop production in this hot arid environment can be improved, compared with groundnut–wheat cropping, by substituting groundnut by mung bean and nutrients application.
STRUCTURE OF NATURAL REGENERATION IN RELATION TO SOIL PROPERTIES AND DISTURBANCE IN TWO SWAMP FORESTS

Veredas (palm swamps) is a type of vegetation associated with watercourses, characterized by the presence of Mauritia flexuosa palm trees. These systems are not well understood and suffer from high anthropogenic pressure. The aims of this study were to describe the natural regeneration of two swamp forests in vereda systems with different anthropogenic impacts and investigate if the variation in these plant communities are associated to edaphic conditions. The study was performed in preserved and impacted sites located in the Environmental Protection Area of the Pandeiros River in northern Minas Gerais. At each site, one hundred 25 m2 plots were established for surveying regenerating shrubs and trees (≥1 cm diameter at the base of the stem and < 3 cm diameter at breast height). Vegetation structure was evaluated by phytosociological parameters, similarity index, and size distribution of individuals. Regenerating strata was correlated with chemical and physical soil analyses. The vegetation at the preserved site was characterized by a higher number of individuals and a lower diversity but contained species that were typical of flooded areas. The results also showed differences in soil nutrient availability between sites that influenced the distribution of species at the two study sites.
Response of black cumin (Nigella sativa L.) plants to the addition of natural fertilizers and the inoculation by bacteria mix and seaweed liquid extract

This experiment was carried out during the two successive seasons of 2017/2018 and 2018/2019 aiming to study the effect of natural fertilizers namely mixed minerals ores; control, 200, 400 and 600 Kg/fed. (fed. = feddan = 0.420 hectares = 1.037 acres) and half recommended dose of NPK fertilizers and the inoculation of mixed of bacteria namely (Azotobacter chroococcum, Bacillus megatherium var Phosphaticum and Bacillus circulans) alone or with seaweed liquid extract , as well as, their interactions on vegetative growth, yield, fixed oil (percentage & yield) and fixed oil components of black cumin (Nigella sativa L.) plants. The highest values of all parameters were observed when the plants received the high rate of mixed minerals ores (600 kg /fed.). In regard to the inoculation with bacteria alone or with seaweed liquid extract, it was noticed that all treatments led to a significant increase in plant height, branch number, shoot dry weight, capsules number, seed yield , fixed oil (percentage & yield). The highest values of these previous characters were obtained when the inoculation with bacteria plus seaweed liquid extract. Generally, the combined effect among mixed minerals ores, the inoculation with bacteria and seaweed liquid extract treatments on Nigella sativa L. , plants parameters was statistically significant. In most cases, the addition of the high rate of mixed minerals ores (600 kg /fed.) plus the inoculation with bacteria plus seaweed liquid extract was the most effective treatment in increasing these parameters. Results of GC-MS analysis of fixed oil revealed that the main fatty acids offered were myristic acid, palmatic acid, stearic acid, oleic acid, linoleic acid, linolenic acid and arachidic acid. The elevated percentages between the previous components were oleic acid followed by Stearic acid and arachidic acid. The treatments of mixed mineral ores and the inoculation with bacteria with seaweed liquid extract increased the former fatty acids in the fixed oil paralleled to untreated control.
Density dependence in post-recruitment processes of juvenile sparids in the littoral of the Mediterranean Sea

While variability in recruitment of young reef fish is now recognised, the question remains how the variation in recruitment will contribute to determining assemblage structure. This has been the basis for an active debate about whether patterns in abundance are determined by the supply of planktonic larvae or whether they result from competition (for space, food, etc.) between potential recruits leading to density-dependent recruitment. We tested population regulation of newly recruited juveniles of Sparidae in the north-western Mediterranean Sea. Recruitment of three species of Sparidae was followed over a three-month period in each of two years to estimate the peak density of new recruits settling from the ocean, the rate of mortality occurring during the first three months after settlement, and the final density after three months. Sites and species were carefully chosen in order to avoid migration during the survey. Initial density of recruited larvae of Diplodus spp. varied among species and sites from 0.045 to 3.8 individuals per metre of coastline. Mortality estimates also varied enormously. Between 24.3% and 99.4% of the initial population disappeared within three months. Our survey demonstrated that both post-settlement mortality (r = 0.847; p < 0.0001; n = 18) and final density (r = 0.818; p < 0.0001; n = 18) were correlated with density of recruitment and consequently that both pre-recruitment (larval phase) and post-recruitment processes regulated sparid populations of the Mediterranean Sea.
The Presence of a Mobile Phone Does Not (Necessarily) Change the Fundamental Processes of Face-to-Face Relational Conflict

This study extends research examining the presence of mobile phones during interpersonal interactions into the context of serial arguments between dating couples. Fifty-eight dating couples (N = 116) had two 10-minute face-to-face serial argument conversations in a laboratory-controlled experiment when technology was either present or absent. The most salient findings were consistent with longstanding findings in the conflict literature: positive communication was associated positively with desirable outcomes (conversational satisfaction, perceived resolvability, and conversation effectiveness) whereas negative behaviors were inversely related to desirable conflict outcomes. Overall, results showed little evidence that the presence of a participant’s smartphone affected the quality of serial argument conversations, but biological sex moderated the impact of technology on conversation satisfaction and perceived conversation effectiveness, such that technology presence negatively impacted women more than men. These findings suggest that the presence of mobile phones does not fundamentally alter effective conflict engagement in general, but there are likely circumstances in which the presence of mobile phones is important.
An empirical study of the impact of leadership, virtuousness and decision-making process on effectiveness of Indonesian private universities

The purpose of this study is to investigate the relationship between servant / authentic leadership, organizational virtuousness, collegial / rational decision-making and organizational effectiveness of the departments at private universities. This study uses 97 faculty members’ data, collected from 78 departments in 17 private universities in Lembaga Layanan Pendidikan Tinggi (LLDikti) III. Structural Equation Modelling - Partial Least Square technique was used to determine statistical significance and path coefficients for the model. The findings indicate that servant leadership significantly affects organizational virtuousness, organizational virtuousness has a significant effect on both collegial / rational decision-making and organizational effectiveness, and organizational virtuousness has a significant effect on organizational effectiveness as well. This research reveals that servant leadership plays a substantial role in developing a virtuous culture, whereas authentic leadership has not contributed to encourage organizational virtuousness in private universities’ departments. Organizational virtuousness practices in departments result in more organizational effectiveness and enable them to exercise collegial / rational decision-making process for the allocation of resources. Moreover, the collegial / rational decision-making approach positively influences the effectiveness of the private universities’ departments. Keywords: Servant Leadership, Authentic Leadership, Organizational Virtuousness, Collegial / Rational Decision-Making, Organizational Effectiveness, Private Universities.
E-Service Quality, Technology Self-Efficacy and Smart Banking Adoption in Sri Lanka

Alongside the increasing usage of smart devices across the industries for the delivery of secure and efficient services, technology self-efficacy is an emerging research notion amongst the scholars. Present research analyses the effect of technology self-efficacy (TSE) and e-service quality (ESQ) towards adoption of smart banking (AoSB) in Sri Lankan commercial banking context. Sample was drawn from Kelaniya University students those who are using smart banking services. Data analysis was performed using 287 questionnaires by using hierarchical linear model. TAM has been extended using the TSE and ESQ variables. Empirical evidence supported the significance of ESQ, TSE and interaction effect (TSE and motive towards TSE) aspects on AoSB. Usage of only the quantitative methods and constrained sample were limitations of the study. However, findings are beneficial for banks, banking application and fintech developers, the same. Originality of the research is that the application of the hierarchical linear model and combination of TAM with variables adopted from SCT and SERVQUEL models, given the specific research context. Upcoming researches could be performed in different contexts by incorporating diverse models and perspectives.

CO2 system parameters in cold oceanic regions

Seawater absorption of anthropogenic atmospheric carbon dioxide (CO2) has led to a range of changes in carbonate chemistry, collectively referred to as ocean acidification. Stoichiometric dissociation constants used to convert measured carbonate system variables (pH, pCO2, dissolved inorganic carbon, total alkalinity) into globally comparable parameters are crucial for accurately quantifying these changes. The temperature and salinity coefficients of these constants have generally been experimentally derived under controlled laboratory conditions. Here, we use field measurements of carbonate system variables taken from the Global Ocean Data Analysis Project version 2 and the Surface Ocean CO2 Atlas data products to evaluate the temperature dependence of the carbonic acid stoichiometric dissociation constants. By applying a novel iterative procedure to a large dataset of 948 surface-water, quality-controlled samples where four carbonate system variables were independently measured, we show that the set of equations published by Lueker et al. (2000), currently preferred by the ocean acidification community, overestimates the stoichiometric dissociation constants at temperatures below about 8 C. We apply these newly derived temperature coefficients to highlatitude Argo float and cruise data to quantify the effects on surface-water pCO2 and calcite saturation states. These findings highlight the critical implications of uncertainty in stoichiometric dissociation constants for future projections of ocean acidification in polar regions and the need to improve knowledge of what causes the CO2 system inconsistencies in cold waters.
PHASE FEEDING IN FATTENING RABBITS

In this study two points were tried to be solved, the first was the effect of phase feeding successive diets, differing in calorie / protein ratio, on fattening performance and digestibility . The second point was the value of using high energy diets while maintaining the crude fiber at its high level. Two experiments were performed in this study, the first was the growth experiment and the second was the digestibility one . In experiment I, seven groups each of 12 weaned New Zealand White rabbits were fed according to different seven feeding regimens , three of them(group I , group IV and group VII) followed single feed program and fed diets 1 (2500 & 17) , 4 (2700 & 18.5 ) , and 7 (2900 kcal ,DE /kg & 19.5 % CP ) while the other four groups followed the three phase feeding system (4 – 7 , 7-10 ,and 10 – 12 weeks of age ) and fed on diets with 2500 kcal / kg & CP % from 20 descending to 14 (group II ) and from 14 ascending to 20 ( group III ) and diets with 2700 kcal/kg with CP % from 21.5 to 15.5 ( group V ) and from 15.5 to 21.5 %(group VI). In experiment II , the digestibility of the different diets in the three phase periods was determined where 4 rabbits were borrowed at time from its respective group . Results revealed that the feasibility of feeding high energy – high protein diets to fattening rabbits . As feed conversion efficiency was linearly improved by increasing energy and crude protein , the DE and CP were efficiently used in growth as it was clear from the figures for kcal /gain : 7.75 & 9.91 vs. 10.56 and protein efficiency ratios :1.92 &1.47 vs. 1.39 for 2900 & 19.5 -, 2700 &18.5 versus 2500 kcal, DE/kg & 17% CP Phase Feeding In Fattening Rabbits. H. M. Abdel-Hafeez & Samar S. Tawfeek 693 diets, respectively . The digestibility of dry matter, crude protein, and ether extract of diet 7 was significantly higher than that of diet 1. Comparing the single feed system with the suggested phase feeding systems indicated that beginning of fattening period on high energy and high protein – diet ( 2700 kcal, DE/kg & 21.5 % CP ) with reducing the protein level, as rabbits grew, to 18.5 and then to 15.5 % led to the most efficient fattening performance . The cost of 1 kg gain was the final judgment . There was reduction in production cost with the suggested feeding regimes to be tested below the recommended control one . The highest cost/kg gain (about 6.4 L.E.) was recorded by group I and group IV (to some extent) while the least cost (5.03) was recorded by group V with savings of about 21 % . The production cost of group II and group VI was in between. Although group V had the least cost, it was not distinctly different from group VII and group III. In conclusion, we recommend the three diets-system of group V to be applied or the feeding system under which group III was raised when the price of oil is high or uneconomical to be added.
Loss and Gain in the Translation of Indonesian Novel Entitled “Cantik itu Luka” into “Beauty is a Wound”

The change of meaning in translation, either in the form of loss or gain, is inevitable. The change is influenced by several factors. This study aims to examine two problems concerning the matter of change of meaning in translation, especially in information loss and gain, by using Kurniawan’s novel, Cantik itu Luka, and its English version, Beauty is a Wound as the reference. The first problem is about the loss and gain occurred in the translation, and the second is about the contributing factors. Both of the problems are analysed by using theory of translation. The first problem is analysed through the conception of loss and gain formulated by Larson (1998); the second is analysed with the conception of translation factor from Catford (1965). In collecting the data, the method used was documentation method, with note-taking technique. The comparison method is used in analysing the data. Based on the analysis that has been done, it can be concluded that loss appears mainly because of the replacement of the source language units with a cultural substitute or related equivalent that cannot represent the whole meaning components. Information gain appears from the change of implicit nuance of the source language unit into explicit, like in the modification of loan word. The contributing factors are both linguistic and cultural. The two factors intertwine with one another in influencing the loss and gain.
Experimental Investigation for a Laboratory Solar Chimney; A Practical Study in Iraq

The solar chimney is a type of passive solar system, used for power and ventilation purposes. For the past decade, a lot of theoretical and experimental studies have been done to improve the thermal performance of a solar chimney by changing some design parameters. The aim of the present work is simulating the thermal performance of a solar chimney system that was investigated based on two parameters, such as heat flux and air gap height under monitored operating conditions in the laboratory. For this purpose, a small solar chimney was built in the laboratory/Kirkuk Technical College. Experiments were conducted on the chimney by choosing three air gap heights 3, 4.5 and 6 cm, and the heat flux variation from 125 to 1000 W/m 2 in eight steps. The simulation results show that the maximum air velocity entering the chimney obtained at a 3 cm air gap height, which is about 2.29 m/s at a heat flux of 1000 W/m 2 , it was higher than the velocity of air gaps (4.5 and 6) cm by (3.6% and 10.6%). The average temperature of the hot plate was also affected by the width of the air gap, as the maximum temperature at the air gap was small. The results also indicate that the maximum thermal efficiency of the system obtained at a height of 3 cm, which is about 25% at a heat flux of 1000W/m 2 . On the other hand, the highest chimney efficiency is obtained at a height of 6 cm.
