The bioefficacy of insecticides against the rice leaf mite,Oligonychus oryzae, Hirst (Acarina: Tetranychidae) was studied under laboratory and field conditions at PAJANCOA and RI, Karaikal. The lab study revealed that among the 11 treatments, methyl demeton 25 EC at 0.42 per cent concentration was superior against nymph and adult mites. Novaluron 10 EC and dicofol 18.5 EC were on par with methyl demeton 25 EC. All the three concentrations of profenofos 50 EC, hostothion 40 EC, mit 50 EC, propargite 57 EC and milbemectin 1 EC were on par with each other. The LC50 values of profenofos, hostothion were 0.002 and 1.165 respectively. Thus methyl demeton followed by novaluron exhibited more ovicidal, nymphicidal and adulticidal effects. Among the acaricides, methyl demeton 25 EC at 1000 ml/ha and novaluron 10 EC at 1000 ml/ha were the best treatments in reducing the population of mite and were equally effective at 1,3,7 and 14 days after treatment, followed by milbemectin under field condition.

Supervised field trials were conducted to evaluate Kinadongold (Phosphamidon 40% + imidacloprid 2% SP) as foliar application for its bioefficacy against sucking insects, phytotoxicity and effect on natural enemies on cotton in Tamil Nadu Agricultural University, Coimbatore. Two season field experiments on cotton revealed that the higher dose of Kinadongold (700 g ha-1) recorded 76.43, 73.28, 76.06 and 69.66 per cent reduction over untreated check for leafhoppers, thrips, aphids and whiteflies, respectively and it was followed by with on par Kinadongold (600 g ha-1), that recorded 74.02, 72.33, 74.34 and 66.77 per cent reduction over untreated check for leafhoppers, thrips, aphids and whiteflies, respectively. There was an initial setback in the population of natural enemies in the Kinadongold treated plots, but it started increasing gradually. Kinadongold did not cause any phytotoxic symptoms even up to a dose of 2400 g ha-1 on cotton.
“The ‘Unpopular’ Children Don’t Flow and Destroy the Atmosphere”: Social Flow in Latency Prevents Peer Exclusion
Authors: Fisher (Grafy) Hannah , Rinat Halabi
Published: September 2023

Peer exclusion is an undesirable phenomenon with serious implications for the present and future of children experiencing it. Growing peer exclusion and bullying rates in elementary-school-age children, especially on social networks, have been examined from a mostly pathological perspective focused on the rejected child or rejecting group. This qualitative study sought developmental explanations for this phenomenon’s pervasiveness during latency. Twelve focus groups of 140 Israeli children in Grade 5 discussed peer exclusion and other social issues. The data were categorized according to the revised Van Kaam method improved by Moustakas. Three themes from aspects of group flow emerged: reduction in the egocentric position and rise in the group’s importance, flexibility with changing social norms, and ostracism when the children perceive a block in the “flow.” The findings confirmed that at latency age, the importance of social flow increases, and rejection and even bullying play a normative developmental role. This study adds an alternative to the literature explaining peer exclusion as the result of the rejected child’s personality or the group’s destructive dynamic. It suggests viewing peer exclusion as a normative development during latency, helping children develop a “social self” free from their egocentric positions to function with a group.
Grandes Temas da Constituição Dogmática “Lumen Gentium”
Authors: Koser Constantino
Published: September 2023

O Concílio Vaticano II não foi convocado para propor novos dogmas, mas para reformular a fé de sempre em linguagem nova, em têrmos que os homens de hoje possam compreender. O Papa João XXIII não se cansou de o frisar, o Pontífice reinante insistiu nisto mais de uma vez, na Aula Conciliar e nas Comissões isto não deixou de ser lembrado. Diante do vasto documento doutrinal que é a Constituição Dogmática Lumen Gentium por isto não cabe indagar: quais são os dogmas novos que propõe — “a priori” a resposta será: “Nenhum!”, pois que se os Padres Conciliares não quiseram definir, não definiram. Definições são atos voluntários e não efeitos “ex opere operato” do exercício do magistério, e muito menos efeitos mágicos...
Ecumenismo Católico após a Terceira Sessão do Vaticano II
Authors: Lepargneur Francisco
Published: September 2023

Sendo concílio pastoral, o Concílio Vaticano II não podia evitar a questão do ecumenismo, em razão da evolução dos espíritos tanto na Igreja católica como fora dela. João XXIII tomou a iniciativa da evolução oficial que terminou no Decreto agora promulgado. Antes da abertura da primeira sessão, já fôra significativa sua decisão de convidar observadores das Igrejas separadas: isto marcou de maneira feliz o clima do Concílio. É preciso dizer logo de início que a grande maioria dos bispos seguiu o movimento, não sem algumas reticências, mas sem deixar dúvida sôbre a perspectiva que o Espírito Santo julgava bom inspirar à Assembléia infalível. Antes de apresentar um balanço da obra conciliar em matéria ecuménica, tentemos situar as dimensões do problema...

Published: September 2023

The black salt marsh mosquito, Aedes taeniorhynchus, is the primary nuisance mosquito in the coastal regions of Florida. This study aimed to establish the baseline susceptibility of Ae. taeniorhynchus to adulticide products used for mosquito control by the Collier Mosquito Control District (CMCD). The Centers for Disease Control and Prevention bottle bioassay was used to test technical-grade and formulated products, and Merus 3.0® was evaluated in semifield cage trials through aerial applications. The results revealed the baseline susceptibility of Ae. taeniorhynchus to the tested materials and the effectiveness of Merus 3.0 to effectively control the Ae. taeniorhynchus. The study provides important information for the development of an integrated mosquito management strategy for controlling Ae. taeniorhynchus mosquito populations in southwest Florida.

Objective: The human immunodeficiency virus (HIV) affects the immune system of human and can lead to Acquire Immunodeficiency Syndrome if not managed, this in turn affect the functionality of the body system especially the kidney. Highly Active Antiretroviral Therapy (HAART) is frequently prescribed as frontline drug in reducing viral load on a carrier. Creatinine and urea are makers for kidney function test. This study investigated the effects of HAART on the urea and creatinine of HIV positive individuals in Enugu, Nigeria. Methods: We recruited about seventy subjects’ age (18-50years) for this cross-sectional study. Twenty-five HIV positive individuals on HAART as test subjects while twenty HIV positive HAART naive subjects and twenty-five HIV negative individuals as controls. 5mls of blood were collected from each participant and used in the analysis of creatinine and urea using colorimetric methods. All data obtained were analysed using Statistical Package for Social Science (SPSS) version 25 computer software and results were expressed as mean ± Standard Deviation. Results: The result obtained shows a significant increase (p<0.05) in both creatinine and urea levels among HIV positive HAART Naive subjects to compare with HIV positive subjects on HAART and HIV negative individuals. When individuals with HIV positive on HAART were compared with HIV negative subjects, there exist no significant different (P> 0.05) in both creatinine and urea levels. Conclusion: This study concludes that HAART significantly increases kidney functionality on HIV positive individuals and ameliorate the effect of the virus on the nephrons of the kidney.

Cholelithiasis is a very common disease throughout the world, but there are still some shortcomings in its treatment. Even after the treatment of "uncomplicated calculous cholecystitis" by the internationally recognized laparoscopic cholecystectomy (LCHEC), complications such as "postcholecystectomy syndrome" after surgery are up to 20 - 40%, and the number of reoperations sometimes reaches 15 - 20%, especially in former Soviet republics (authors .... and others). The article shows the role of fibrocholangioscopy aimed at reducing these complications. At the same time, after choledocholithotomy, it almost completely excludes residual stones and clarifies the diagnosis of BS VP. In addition, with choledocholithiasis, cholangitis is almost always found, more often catarrhal (up to 46%), purulent (in 24% of patients) and often ulcerative-necrotic forms of cholangitis (22%), sometimes reticular cholesterosis (8%), as well as tumors hepatic ducts and polyps of BS duodenum. Therefore, as a result of fibrocholangoscopy, the accuracy of diagnosing choledocholithiasis, BS VP, cholangitis, etc., reaches 95-99%. which helps to reduce the number of complications, such as recurrent and especially residual choledocholithiasis, BS VP and cholangitis, etc.

One effort to produce quality students is to increase teacher motivation and communication skills. School leaders need to pay attention to teacher motivation in dealing with difficult situations in order to improve the quality of education. In this assumption, motivation and communication are considered to be able to improve teacher performance and achieve educational goals. In addition to the teacher's communication role, the principal's leadership style also has an important influence. If motivation and communication are not optimal, this can have a negative impact on teacher performance. This phenomenon has the potential to result in a decrease in teacher performance.The purpose of this community service (PKM) view is that the success of schools in improving teacher performance can be influenced by the training and counseling provided to teachers, with the aim of improving the quality of teacher resources. One effort that can be done is to provide motivation and teach how to communicate well between teachers and students in overcoming obstacles in the teaching process and dealing with teaching-learning situations. The principal's concern through respect for teacher performance also plays a role in this, with the leadership style shown by the principal.Motivational counseling, attended by teachers and school principals, yielded results (1) Community Service Activities (PKM) can provide enthusiasm for changing maximum performance in school governance; (2) Community Service Activities (PKM) can improve and change communication between teachers and parents of students to become more humane and create mutual trust and respect; (3) Community Service Activities (PKM) can provide changes and evaluations of the Principal's leadership style and touch on improving teacher performance, building trust in teachers for the potential of teacher resources.Hope for teachers and school principals in PKM activities to provide changes and improve teacher performance and integrated communication between teachers, school principals and student guardians, so as to have an increased performance impact to assist in governance at the GKB Gresik Muhammadiyah 1 Elementary School Foundation
