Akhlak are the concern of people everywhere, both in advanced societies and underdeveloped societies, because if in a society there are many people whose Akhlak have been damaged, the society will be damaged. This shows that the position of morality in human life occupies a very important position, both as individuals and as members of society and the nation. "The rise and fall of a nation depends on the moral state of the nation itself. If their Akhlak are good, they will prosper both physically and mentally, but on the contrary if their Akhlak are bad, the nation will be damaged. In the hadith of the Prophet Muhammad Saw. which means “Educate your children because they were born to live in an age different from yours”. Because children are a gift or a mandate from Allah Swt. which must always be maintained and maintained continuity

Character education can be characterized by a whole-souled, wholesome, moral, and disposition education at rendering good decisions, maintaining what is good, and wholeheartedly displaying goodness in daily life. The prophet (peace and blessings be upon him) was the messenger of god and the educator. He got disciplined directly from his Lord so as to have the most perfect character on the face of this earth, so as to become a great man with the testimony of god enshrined in his word: “and how virtuous you truly are” the great testimony of god of the prophet (peace) is evidence that his moral character is great and glorious since the creation of it. He was renowned among his kind as honest and trustworthy. As a majestic being, he had the glorious duty of the supreme being, the edifying and perfecting of men, as the prophecy says: “that I was sent forth to perfect men.” He succeeded in carrying out a great commission by turning the evil community into a society of faith and civility, while printing out noble characters
Studies of the Gust and nuclei content of the air near the ground and their effect on atmospheric Thomas, electricity parameters
Authors: MANI A. , HUDDAR B. B.
Published: February 2022

Regular measurements of the dust and nuclei contient of the air near the ground at Poona were made during 1967-69 to study the characteristic elements of natural pollution n6ar the ground, its origin and its variation with time seasons and altitude. The electrical field strength the positive and negative conductivity of the air and the number of positively and negatively charged small ions in the atmosphere near the ground were also measured at the same time. These observations were repeated at two mountain stations during February and June 1969. The dust content and the electric field show seasonal and diurnal variations opposite to those of the small ion density and electrical conductivity. Thus, while the electric field is a maximum in winter, the conductivity and small ion content is a maximum during the monsoon months and the dust content a maximum in the pre-monsoon summer months. A marked increase in the electric field and the dust and condensation nuclei content is observed since similar measurements were last made in 1933-1937 at Poona, with a corresponding decrease in small ion count and conductivity. These large variations are associated with the increased industrialisation and urbanisation of the regions around Poona during the last thirty years.

Authors: RAJAMANI S. , TALWALKAR D. R. , RAY S. P. , UPASANI P. U.
Published: February 2022

A scheme for objective analysis of wind field over Indian region was drawn up using optimum interpolation method. For this the autocorrelation functions and the structure functions of the wind field over India have been computed for 850, 700 and 500 mb levels.

 

These statistical structure functions were used in calculating the weighting factors for the observing stations with respect to the given grid point and objective analyses were made at 850 and 700 mb levels for eight days from 24 July to 31 July 1969. In order to evaluate the objective analyses quantitatively RMS errors were computed by interpolating the winds at the observing stations from the objectively analysed field and comparing with actually observed winds, Also, centres of the monsoon system obtained in objective analyses were compared with those in  subjective analyses.

Risk analysis for kharif crop production under rainfed conditions in Nagaur district
Authors: RAO G. G. S. N. , VYAS B. M.
Published: February 2022

The planting schedules, the probabilities of occurrence of sowing rains and the chances of getting satisfactory yield for crops of 75 to 90 days duration at five different stations in Nagaur district are presented. The study reveals that short duration crops are less risky compared to medium duration crops. The low yields in respect of medium duration crops is due to the fact that crops suffer moisture stress during physiological maturity stage. This can be avoided to some extent either by transplanting the crops around 26th week or by providing supplementary irrigation during the stress period with the surplus water harvested if any.  Measures to be taken under severe to moderate stress condition have also been indicated. The possibilities of raising rabi crops under conserved moisture condition in the high rainfall zones have been examined.

Authors: DEWAN B. N. , . JAIPAL , KUMAR S.
Published: February 2022

The flux of air and moisture in the Bay of Bengal during Monex 1979 period when the Soviet ships were moving in that area, have been computed. It is found that the northward transport of air and moisture across the equator is confined only to the area west of 85 deg. E. Eastwards of 85 deg. E, the reversal of transport is found to occur .The computations of the air and moisture flux values have also been carried out for the central Bay of Bengal in July for the period when the ships were stationed there. Comparison between the AUK values for the comparatively strong and weak phases of monsoon reveals that while the northward flux does not show any appreciable variation, the eastward flux changes significantly, becoming; more than double during the strong phase as compared with that of the weak phase, both along the east coast and in the central Bay.

Return period analysis of extreme rainfall events
Authors: GOYAL S. C. , KATHURAI S. N.
Published: February 2022

The return periods analysis of extreme events of rainfall for selected 15 stations of Krishna river basin have been studied and presented in this paper. The annual one-day rainfall data for 60-years (1901-60) was used for the study. The rainfall estimates were computed for different return periods using tow different distribution and Fisher & Tipett type II distribution. Return periods corresponding to highest recorded rainfall were interpolated for both the distributions. Results show that while Gumbel’s distribution seems to indicate very high return periods of extreme events, the Fisher & Tipett type-II distribution provides lower estimates of the recurrence interval. As rainfall events are randomly distributed in nature, the return periods of outliers should also be determined with reasonable accuracy. The present study shows that the rainfall estimates for different return periods as obtained by using Fisher & Tipett type II distribution technique are much higher than those obtained by using Gumbel;s technique. It is suggested that Fisher & Tipett type II distribution may be preferred for evaluating the return periods of extreme rainfall events to Gumbel distribution.

Parental practices influence intake of calcium-rich foods and beverages (CRFB) in adolescents. This study aimed to test two posters promoting such parental practices for comprehension, cultural and personal relevance, and ability to motivate parents to encourage CRFB intake. Interviews were conducted with 14 Hispanic and 6 Asian parents to evaluate two posters entitled “Good play starts with calcium” and “Strong families start with good nutrition.” Responses were reviewed for themes. For “Good play,” both racial/ethnic groups of parents understood the message to provide CRFB. Only Hispanics, however, recognized the connection between calcium and strong bones. For “Strong families,” both groups had difficulty understanding that foods pictured were calcium rich. Both posters were considered culturally and personally relevant; however, not all respondents indicated motivation to provide CRFB. Modifications are needed to emphasize the connection between images and taglines and calcium intake for use in a future intervention to improve CRFB-promoting practices.
The Emotional Context of Higher Education Community Engagement
Authors: Ross J. Ashleigh , Stoecker Randy
Published: February 2022

Higher education community engagement has an emotional context, especially when it focuses on people who have been traumatized by oppression, exploitation, and exclusion. The emotional trauma may be multiplied many times when those people are also dealing with the unequally imposed consequences of disasters. This paper is based on interviews with residents of the Lower 9th Ward of New Orleans who experienced various forms of higher education community engagement in the wake of Hurricane Katrina. The results are surprising. First, residents most appreciated the sense of emotional support they received from service learners and volunteers, rather than the direct service those outsiders attempted to engage in. Second, residents did not distinguish between traditional researchers and community-based researchers, and perceived researchers in general as insensitive to community needs. The article explores the implications of these findings for preparing students and conducting research in any context involving emotional trauma.

Environmental problems can overcome by changing the mental attitude of humans as environmental destroyers to humans who are aware of their environment. The focus in research is to find out and then interpret the results obtained related to the presence or absence of influence between the level of knowledge and attitudes of traditional miners on behavior. The number of samples used was 212 respondents spread over traditional mining areas of the community. Data is obtained from surveys using questionnaire instruments and interviews with traditional miners. The data is then analyzed Structural Equation Model (SEM) using IBM AMOS 23. The results of validation and reliability and goodness of fit (GOF) indicate that the model is feasible and fit. The results of the analysis show that there is a significant impact between the variables of knowledge and attitudes towards the behavior of the mining community. The condition of enough knowledge is not able to change people's behavior to manage the environment. The results obtained are the same as attitudinal variables that show contra to the environment. All ways are done to get profits without seeing the consequences. The attitude of the government must be more assertive in controlling illegal mining that has damaged the surrounding environment. Humans who are aware of their environment are humans who already understand and apply attitudes and behaviors that care about the environment and apply the principles of ecology and environmental ethics.

Sources of electrical energy is a basic need in life, both in industry and the necessities of life. Along with the depletion of fossil energy, it is necessary to develop a biomass energy source as a fuel for electrical energy. For this reason, this study aims to create innovative power plants using biomass energy as fuel. The steam turbine is a prime mover that converts the potential energy of steam into kinetic energy and then converts it into mechanical energy in the form of a turbine shaft rotation, directly or with the help of a reduction gear, connected to the mechanism to be driven. In a study to analyze the performance of a steam turbine with gas fuel and wood charcoal. Wood charcoal is activated carbon from combustion, which in this study uses wet steam to drive the shaft with variations in pressure (7Bar, 6Bar, 5Bar and 4Bar). From the results of the study, the maximum power produced by a laboratory-scale steam turbine is 20.84 Watt at a given pressure of 7 Bar and the maximum efficiency of a laboratory-scale steam turbine with wood charcoal fuel is 70.02% with a pressure of 7 Bar and Generator efficiency is 21.87%. or 17.5 Watts, the electrical power generated from the speaker power generator is 80 Watts. For the results of the comparison of the performance of the steam turbine with wood charcoal fuel media with LPG gas, it can be proven from the turbine efficiency it is better to use gas fuel with a different ratio (at a pressure of 7 bar Wood Charcoal / LPG): 70.02%/78, 12%), while the efficiency of the generator is at a pressure of 7.Bar (21.87, 25%), so LPG fuel is more effective than wood charcoal but from local fuel Wood charcoal is more readily available and cheaper.

Authors: Boontoterm Panu , Feungfoo Pusit
Published: February 2022

Background: Several dynamic parameters have been used clinically to predict volume responsiveness and to guide fluid administration of which passive leg raising (PLR) is one of the most reliable techniques. PLR induces rising in cardiac output attributes through an unstressed volume mobilization from legs to heart causing autologous preload increment. Appropriate fluid resuscitation is essential and can be optimized by hemodynamic-based approach to vasodilatory hypotension.

Objective: This study aimed to evaluate the effectiveness and safety of PLR at early resuscitation among patients with vasoplegia.

Methods: We conducted a comparison study concerning an experimental design using a single blinded assessment of the outcomes that assigned patients with shock to be treated with PLR or flat position at early resuscitation. Forty patients with shock were included in this study. Twenty patients performed PLR at early resuscitation compared with the others that performed in the flat position and were measured for cardiac output (CO), mean arterial pressure (MAP), diastolic blood pressure (DBP), heart rate (HR), central venous pressure (CVP) and systemic vascular resistance (SVR) immediately after the procedures. The primary outcome was to evaluate the effect of early PLR on hemodynamic variables among hypotensive patients by comparing the difference in CO while the secondary outcomes were differences in MAP, DBP, HR, CVP, SVR, survival at hospital admission and the pulmonary complications of chest x-rays between the two groups.

Results: No difference was observed in baseline characteristics between the two groups of patients. Compared with the flat position, PLR at early resuscitation significantly increased CO (3.57 ± 0.27 vs. 2.2 ± 0.18 L/min, p = 0.037), MAP (22.48 ± 5.6 vs. 10.83 ± 4 mmHg, p<0.001), DBP (19 ± 0.20 vs. 1.23 ± 0.12 mmHg, p=0.001) and CVP (4.52 ± 0.19 vs. 2.18 ± 0.13 mmHg, p=0.002). However, no differences were observed in HR, SVR, pulmonary complications of chest X-rays [2 (10%) vs. 1 (5%), p = 0.23] as well as survival at hospital admission [16 (80%) vs. 13 (65%), p = 0.48] between the two groups.

Conclusion: Among patients with shock, PLR at early resuscitation significantly increased CO, MAP, DBP and CVP than that of those performing the flat position. No differences were found in HR, SVR, pulmonary complications; PLR did not improve survival to hospital admission.
COMPARISON OF PERCUTANEOUS PEDICLE SCREW FIXATION AND PEDICAL SCREW FIXATION IN CONVENTIONAL INCISION IN THORACOLUMBAR FRACTURE
Authors: Jeamanukulkit Surojn
Published: February 2022

Background: Originally, patients with unstable thoracolumbar spine fracture were treated using pedicle screw fixation, a conventional incision. However, the small incision percutaneous pedicle screw fixation (PPSF), a new device, has been recently introduced which could save surgery time, reduce blood loss and improve clinical recovery.

Objective: This study aimed to evaluate postoperative outcomes of the PPSF, compared with the open pedicle screw fixation (OPSF) in conventional incision among patients with thoracolumbar fracture.

Methods: A retrospective study of 54 cases of patients with thoracolumbar spine fracture without neurological deficit was included in the study. The data were collected from medical records of patients admitted to Rayong Hospital from January 2017-December 2019. Results: Patients aged from 18-46 years (32.35+ 8.52) were mostly males (59.2%). Types of fracture included burst (72.22%). The most common level of thoracolumbar spine fracture was L1 (37.04%). Mostly, the cause of injury was fall from height (53.70%). The mean postoperative stays in the PPSF and OPSF groups were significant, 3.09±.59 and 6.16±1.003 days, respectively (p<0.05). The mean intraoperative blood losses of the PPSF and OPSF groups significantly differed, 44.35±15.02 and 466.13±87.92 mL, respectively (p < 0.01). However, the mean kyphotic angle reduction of the PPSF (24.43±2.74 degrees) and OPSF (24.87±2.55 degrees) groups did not significantly differ (p > 0.1). The mean postoperative pain score (VAS) at the first day in the PPSF and OPSF groups were 6.43±.94 and 6.61±.98, respectively, which did not significantly differ (p > 0.1).

Conclusion: PPSF spinal fracture treatment could reduce the amount of bleeding during surgery and reduce the length of hospital stay. However, the results of both types of surgery did not differ regarding postoperative pain, decreased kyphotic angle and surgical time.

Level of Sexual Health Knowledge and One-Night Stand Relationships among University Students
Authors: Jahanfar Shayesteh , Khalaf Zahra Fazli
Published: February 2022

Knowledge of sexual and reproductive health is believed to improve healthy sexual attitudes and behaviors, and decrease sexual risk-taking behaviors. Casual sexual relationships, such as one-night stand relationships, have become pervasive practices among heterosexual college students in the United States, despite imposing negative consequences on individuals’ sexual and reproductive health outcomes. This study employed a cross-sectional method to explore the relationship between the knowledge of sexual and reproductive health and a belief in one-night stand relationships among 804 university students in the United States. Participants answered a questionnaire from the World Health Organization, administrated through Qualtrics software. Descriptive statistics, bivariate analysis, and logistic regression analyses were performed. Significant findings were reported by unadjusted and adjusted odds ratios with 95% CI. The findings of this research showed that there was a positive relationship between the level of knowledge and a belief in a one-night stand relationship. The findings also showed that male students are more likely to report a belief in one-night stand relationships compared to female students. In addition, a large number of students did not receive information about condom use, and there was a significant negative correlation between being religious and a belief in one-night stands. This study offers insight into the inadequacy of sexual health knowledge among university students. It also suggests that gender-specific knowledge should be a necessary part of the sexual and reproductive health education programs. Clinical and public health implications are discussed.
In situ Field Capacity in Brazilian Soils and a Derived Irrigation Management Practice Based on Water Suction

Field capacity (FC) is a fundamental parameter in soil and water engineering and hydrologic modeling. Despite its relevance, the in situ determination of this parameter is not standardized and its determination by indirect methods is dubious. This study presents a method of calculation of in situ FC and its corresponding water suction (hFC), using the van Genuchten equation for water retention and the pedotransfer function by Ottoni Filho et al. (2016) for standardized in situ determination of FC. The methodology was applied to HYBRAS, a database of hydrophysical data for Brazilian soils with 1,075 soil samples from 15 Brazilian states. FC and hFC were confirmed to depend on textural class and pedogenetic origin (weathered and unweathered soils). Our analysis justified why FC must not be determined based only on a single predetermined water suction value. A simplified method is proposed for the management of irrigated soils through the determination of water suction in the root zone and the mode and confidence interval values of hFC corresponding to soil groups formed from textural classes and pedological nature. Various statistical calculations of FC and hFC are presented for these groups.
