Comparison of surface characteristics and micro hardness of AISI D2 tool steel and LM13 aluminum alloy machined under dry EDM (green machining) process

In this experimental work, the micro structure and the micro hardness of the surfaces machined under the dry EDM process is analyzed for AISI D2 tool steel and LM13 aluminum alloy. The experiments were conducted using copper tool electrode. Few modifications were made in the tool for conducting the experiments under dry EDM process. Discharge current, pulse on time, voltage, pressure, tool rotational speed and the duty factor were used as the various process parameters and their influence over the micro structure and micro hardness of the machined surfaces were analyzed. Better results were observed in the dry EDM process for AISI D2 tool steel, whereas dry EDM process did not reveal appreciable results for LM13 aluminum alloy.
Bat (Mammalia: Chiroptera) biodiversity in a subtropical inselberg ecosystem of Northeastern Argentina

Introduction: Rocky outcrops influence both micro and macro habitat for plants and animals by increasing the availability and predictability of food, providing shelter, and unique microclimatic conditions. Objective: We describe the bat assemblage in three isolated rocky outcrops and their surrounding pediments, adding new data about trophic guilds and roosts. Methods: We surveyed the bat fauna of Paraje Tres Cerros, Corrientes Province, Argentina, exploring 13 sites during 26 field trips, using mist nets and search of roosts. We made an accumulation species curve and calculate inventory completeness. The similarity and composition of different habitats was compared by a Non-Metric Multidimensional Scaling (NMDS) and an ANOSIM test. Results: We reported 13 species, with a completeness inventory of the 80 % (Jacknife1), corresponding to the families Vespertilionidae, Molossidae and Phyllostomidae. The insectivorous bats were the best represented guild. We found nine types of roost for eight species in different sites. The analysis expressed low differences in the species composition between both types of habitats in the area. Conclusions: The rocky outcrops and their pediments are important ecosystems for the conservation and diversity of the bats in the region, since their assemblages are regionally unique.
DO WE SEE NATURAL Wolbachia IN FIELD-CAPTURED

A new alternative in controlling mosquitos, the arbovirus vectors, has emerged in recent years and commonly called Wolbachia method. Currently, a large trial is still running since 2017 in Indonesia to assess the efficacy of Wolbachiainfected mosquito deployment in reducing dengue incidence in Yogyakarta. Awaiting the trial result before implementing the same method in Bandung, however we could not find any reports on the distribution of natural Wolbachia in urban mosquitos from Indonesia, especially for Culex sp and Aedes sp of Bandung. Therefore, field surveys were conducted at four locations (3 subdistricts) from Bandung City and its surrounding area to screen for the natural mosquito infection status of Wolbachia by PCR and sequencing method. We found that 83.3% of Bandung-captured Cx. quinquefasciatus were female, and 88.2% of those female were naturally infected with Wolbachia. The infection rate was lower for the male Culex, bringing down the total infection rate of Cx. quinquefasciatus to be around half of the captured mosquitos. However, the results from both female Ae. Aegypti of different locations revealed baffling very weak bands on the agarose gel. As for the infection status of Bandung’s captured Ae. aegypti, it is worth to wait for our further results as well as reports from other studies. And thus, we opted to keep the inconclusive status of Wolbachia infection in Ae. aegypti from Bandung City.
Does Person-Job Fit among Nurses Really Matters? An Empirical Study: Effect of P-J Fit on Job Outcomes of Nurses of Pakistan with Agreeableness as a Moderator

The purpose of this study is to find out that whether the jobs of nurses in Pakistan are fulfilling their necessary requirements or not. This issue is being analyzed by the relation of Person-Job (P-J) Fit with three different Job Behaviors and the whole relation is being tested under the moderation of Agreeableness, which is a personality trait of Big 5 Model. A survey method is deployed, questionnaires are used to obtain data. 120 Nurses were accessed from different hospitals of Islamabad/Rawalpindi. Data was analyzed through statistical tests and regression analysis. Findings of the study highlight that P-J fit is related positively to job satisfaction of nurses and negatively to their Turnover Intentions. Where no significant impact of agreeableness as a moderator is found for this study. The Sample size was too small (120 participants). This may restrict the generalizability of the studies. In Pakistani context, only a limited study has been conducted on nurses. Thus, this piece of research will play a significant role in enhancing and boosting the confidence of deprived nurses of Pakistan by identifying the causes of negative job outcomes and help in mitigating those triggers.
Virtuous Qualities and Personality Traits of Wise Individuals

Abstract Introduction: Wisdom is a desired master virtue and a lot can be learnt from the qualities and personality traits of wise individuals. Philosophers and psychologists have attempted to understand the qualities that make an individual wise because wisdom entails a life of personal growth and maturity. Keeping the benefits of wisdom in mind, the present study investigated various virtues and personality traits that characterize it. Method: Wisdom was studied in relationship with Big Five Personality Traits (extraversion, openness to experience, agreeableness, neuroticism, conscientiousness) and Virtues (wisdom and knowledge, courage, humanity, justice, temperance, transcendence) among a sample of 360 Indian adults in the age range of 18-75 years. Pearson’s product moment correlation and stepwise multiple regression analyses were conducted with wisdom as the criterion variable. Cross-sectional predictors of wisdom were also found across the three age groups i.e. young adults, middle aged adults, and older adults. Results: Results revealed that humanity, transcendence, extraversion and wisdom and knowledge virtues account for 29% variance in wisdom in the total sample. The virtues of wisdom and knowledge and openness personality trait emerged to be the most significant predictors of wisdom in young adults (n=120) and accounted for 17% variance. Middle-aged adults (n=120) reflected transcendence, temperance and humanity virtues as significant predictors of wisdom accounting for 41% variance. The older adult group displayed transcendence as the only significant predictor of wisdom accounting for 5% variance. Conclusion: The present study indicates that in order to develop wisdom, one needs to inculcate healthier personality traits of openness, agreeableness, conscientiousness, humility, forgiveness, ego transcendence, gratitude, hope, playfulness, humor, kindness, curiosity, judgment and perspective-taking abilities.
On-Farm Comparative Evaluation of Growth and Reproductive Performance Traits of Washera and Gumuz Sheep Populations in Northwestern Ethiopia

Growth and reproductive performance traits are traits of economic importance for sheep selection and productivity improvement. This study aimed at comparative evaluation of growth and reproductive performance traits of Washera and Gumuz indigenous sheep in the highland and lowland agro-ecologies of northwestern Ethiopia. Data on growth performance traits were collected from 412 Washera (162 male and 250 female) lambs and 208 Gumuz (72 male and 136 female) lambs. Concurrently, data on reproductive performance traits were collected from 406 Washera (130 rams and 276 ewes) sheep and 213 Gumuz (75 rams and 138 ewes) sheep. General linear model (GLM) univariate procedure was employed to analyze the collected data. Mean±SD values of adjusted yearling weight of Washera and Gumuz sheep was 21.80±1.91 and 20.37±1.85 kg, respectively. Breed type affect live weight significantly (P<0.001). Mean±SD values of age at first lambing, lambing interval and annual reproductive rate of Washera sheep were 11.69±1.96 months, 9.27±3.53 months and 2.12 lambs, respectively. The corresponding values for Gumuz sheep were 12.51±1.95 months, 10.43±1.25 months and 1.71 lambs, respectively. Production and reproduction performance values for traits of Washera and Gumuz sheep were comparable to other Ethiopian and African breeds. These values can be used to set up breeding objectives for optimizing breeding schemes of sheep breeding program. In addition, the varied minimum and maximum values of growth and reproductive performance traits indicates that there is within breed variability. This variation could be used as a basis for within breed selection among indigenous sheep by giving special consideration to growth rate traits, believed to have medium heritability values.
Genetic diversity of divergent redclaw crayfish Cherax quadricarinatus (Von Martens, 1868) populations evaluated to initiate a breeding program in Mexico

Cherax quadricarinatus is a decapod crustacean of interest to the aquaculture industry. In Mexico, a significant effort has been made to improve biological requirements, but the genetic characteristics are unknown. We examined the genetic diversity and differentiation in four populations in Mexico (three commercial farms and one feral population), as well as one research line from Argentina, used as reference. To initiate a founder stock in a genetic improvement program, we analyzed five microsatellite markers. The genetic diversity in terms of the number of alleles was low to moderate (2.8-6.2) in Mexican populations than the Argentinean sample (8.8). A pairwise Wright's Fst analysis showed that all populations were significantly different (P < 0.5). Cross-breeding organisms from a different population are suggested to increase genetic variability before initiating a founder stock with higher genetic variation.
Interpreting estimated Observation Error Statistics of Weather Radar Measurements using the ICON-LAM-KENDA System

Abstract. Assimilation of weather radar measurements including radar reflectivity and radial wind data has been operational at the Deutscher Wetterdienst, with a diagonal observation error (OE) covariance matrix. For an implementation of a full OE covariance matrix, the statistics of the OE have to be a priori estimated, for which the Desroziers method has been often used. However, the resulted statistics consists of contributions from different error sources and are difficult to interpret. In this work, we use an approach that is based on samples for truncation error in radar observation space to approximate the representation error due to unresolved scales and processes (RE) and compare its statistics with the OE statistics estimated by the Desroziers method. It is found that the statistics of the RE help the understanding of several important features in the variances and correlation length scales of the OE for both reflectivity and radial wind data and the other error sources from the microphysical scheme, radar observation operator and the superobbing technique may also contribute, for instance, to differences among different elevations and observation types. The statistics presented here can serve as a guideline for selecting which observations to assimilate and for assignment of the OE covariance matrix that can be diagonal or full and correlated.
Tracking Audience Statistics with HyperLogLog

HyperLogLog is the state of the art nearly optimal algorithm for approximate cardinality estimation. We consider the application of HyperLogLog for building scalable systems for internet audience reach reporting. We present an extension of HyperLogLog that enables tracking additional information about the audience, such as demographic distribution, frequency histogram or fraction of spam. We also give an intuitive explanation of why HyperLogLog works, which we ﬁnd useful, as intuition of the proof in the original HyperLogLog paper requires a lot of eﬀort to understand. This extension and the intuition are itself generic and are not limited to internet reach reporting.
Antecedents and consequences of brand relationship quality: perceptions of active members of hotel loyalty program

Loyalty programs are the most popular “value–added” defensive customer relationship management (CRM) strategies used by hotel chains to foster repeat business. They are developed to reward frequent customers, generate information about customers, manipulate customers’ behavior, and to compete with other hotels. Members of the loyalty programs have become business builders by buying more, paying premium prices, and bringing in new customers by referrals (O’Brien and Jones, 1995). These programs no doubt are integral part of today’s competitive hotel industry and millions of dollars are spent every year on managing the programs through giving away valuable freebies to keep customers coming back.
A Sentiment Analysis of Egypt’s New Real Estate Registration Law on Facebook

In response to the increasing influence of social media networks on shaping the public opinion, sentiment analysis systems and applications have been developed to extract insights and gain an overview of the wider public opinion behind certain topics so as to support businesses, manufacturers, government agencies, and policymakers with their decisions and plans. Despite the importance of sentiment analysis in providing policymakers with effective mechanisms to understand the attitudes of customers and citizens which can be usefully used in decision-making processes and planning for the future, so far studies on sentiment analysis are very limited in Egypt. Much of the work is still done using survey tools such as questionnaires and polls to gather information about the citizens’ attitudes towards given issues and topics. Despite the effectiveness of such methods, citizens’ reflections on social media platforms and networks remain more powerful in providing comprehensive insights and overviews. Furthermore, social media-based sentiment analysis is usually more representative being based on larger numbers of participants, which has positive implications to reliability. Opinions expressed on social media are often the most powerful forms of feedback for businesses because they are given unsolicited. In light of this argument, this study seeks to provide a sentiment analysis of Egypt’s New Real Estate Registration Law on Facebook. To extract information about the users’ sentiment polarity (positive, neutral or negative), Facebook posts were used. The rationale is that Facebook is still the most popular social media platform in Egypt. Text classification was then used for classifying the selected data into three main classes/values: Positive, Negative, and Neutral. The findings indicate that sentiments expressed in the users’ posts and comments have a significant negative attitude towards the new law. Despite the effectiveness of the automatic evaluation and analysis of the sentiments and opinions of the users in social media concerning the new Real Estate Registration Law, linguistic approaches including Critical Discourse Analysis (CDA), functional linguistics, and semiotics need to be incorporated into sentiment analysis applications for gaining a better understanding of people’s attitudes towards specific issues. Keywords—Egypt; Facebook; opinion; real estate registration law; sentiment analysis; social media
A SYSTEMIC APPROACH TO INFORMATION AND CYBER SECURITY

Design Based Threat, or DBT, is a common principle for physical and cyber protection, which is based on threat assessments. The protection, cyber or physical, will be planned based on the type of the identified threat. While we acknowledge the importance of the DBT, we argue that following this line of reasoning may limit our ability to grasp other vulnerabilities the system may have due to the following assumptions:
Use of injectable progestogen-only contraceptives at the family planning clinic of the Nnamdi Azikiwe University Teaching Hospital Nnewi, Nigeria

This retrospective study investigates the use of, complications and discontinuation of injectable progestogen-only contraceptives at the family planning clinic of the Nnamdi Azikiwe University Teaching Hospital Nnewi, Nigeria. 392 (29.1%) of the 1345 new clients chose injectable progestogen-only contraceptives. Among them, 51.5% were spacers while 48.5% were limiters. Also 94.9% of the clients used depot medroxyprogesterone acetate (DMPA) while 5.1% used norethisterone enanthate (NET-EN). Majority of the acceptors belonged to the 30-34 years age bracket (35.7%), were grandmultiparous (63.8%), and had achieved secondary education and above (74.5%). Ninety (23.0%) clients experienced various forms of side effects, of which menstrual irregularity was the commonest (5.6%). The overall discontinuation rate was 6.1%, and the main reason for discontinuation was desirefor pregnancy (4.1%). There was no pregnancy reported during the study period. The likelihood of reporting complications was significantly associated with age (x 2 = 34.06; p=0.00), and level of education (x 2 =10.18; p=0.00). The injectable progestogen-only contraceptives are not widely accepted in our centre, and are associated with a low discontinuation rate. There is need to scale up their use in the family planning program in the area.

Brain-Based Learning: The Impact on Student’s Higher Order Thinking Skills and Motivation

The research objectives are to determine the effects of the Brain-based Learning (BBL) approach on students' higher-order thinking skills and student motivation to learn physics. This research used the quasi-experimental pretest-posttest design. The sample of this research consisted of two tenth-grade science classes chosen by simple random sampling technique. This research population was all tenth-grade students of a senior high school in Yogyakarta. The data were obtained by test and non-test techniques. The result shows that BBL approach affects on the students' higher-order thinking skills (sig. 2-tailed = 0,003 α = 0.05). Further, it also improves students' higher-order thinking skills represented by the N-Gain value (experimental class N-Gain = 0.40 control class N-Gain = 0.21). On the other hand, not only on student's higher-order thinking skills, BBL approach bring the significant effect on students’ motivation in learning physics (sig. 2-tailed = 0,000 α = 0.05) as well as could improve it (experimental class N-Gain = 0.55 control class N-Gain = 0.04). It means that the BBL approach could improve higher-order thinking skills and students' motivation more effectively than the traditional approach
Time Variations of Sediment Floc Size and Density by using Settling Column Data

The investigation of settling process and cohesive sediments consolidation in dam reservoirs and beaches is one of the most important issues playing an effective role in different descaling and sediment controlling designs, including dredging projects and hydraulic sediment removal operations. The superfine cohesive sediments even settle in the canals in which the existing standard criteria of design have been observed. They have also settled in dam reservoir and resulted in trapping efficiency near 100%. In addition to reducing the service life of reservoir, this problem has also changed the limpidity of the water released from the existing reservoir, ecology and morphology of the downstream river. In the beaches and seaports, the cohesive sediments settlement has caused an increase in dredging costs. In many cases it is impossible to overcome this phenomenon in practice [1].
Does Virtual Field Experience Deliver? An Examination into Virtual Field Experience during the Pandemic and Its Implications for Teacher Education Programs

This study attempted to examine whether academic performance of pre-service teachers (PST) in virtual field experiences was the same as that of their peers in the previous semester who had regular face-to-face field experiences. Data for this study included PST’ scores in three course sections in the Spring 2020 semester at a mid-size public university located in the Midwest of the United States where all of their field experiences were conducted virtually and compared with that of their peers in the Fall 2019 semester when all of their field experiences were conducted face-to-face. Our findings indicated that PST’s academic performance in the virtual field experiences was the same as that of their peers in the previous semester who had regular face-toface field experiences.

Effect of Deep Breathing Exercise on Heart Rate Variability of Different Age Groups

Breathing affects our respiratory, cardiovascular, neurological, gastrointestinal, muscular, and psychological wellbeing. Breathing also has a general effect on our sleep, memory, and ability to concentrate and plays an important role in improving our energy level. To study the effect of deep breathing exercise on heart rate variability of different age group. Pranayama, most known as deep breathing exercises, is a compound word with Pran and Ayama. The increase in HRV may be since the reduction in breathing frequency caused by the breathing training allows the respiration to modulate the sympathetic cardiac outflow along with the vagal outflow which result in increased HRV. Compare the heart rate variability and autonomic function test between two groups before practicing deep breathing exercise. Compare the heart rate variability and autonomic function test between two groups after practicing deep breathing exercise. To find out the effect of regular practice of slow deep breathing exercise in two groups.
