On certain equations of arbitrary length over torsion-free groups

Let $G$ be a non-trivial torsion free group and $t$ be an unknown. In this paper we consider three equations (over $G$) of arbitrary length and show that they have a solution (over $G$) provided two relations among their coefficients hold. Such equations appear for all lengths greater than or equal to eight and the results presented in this article can substantially simplify their solution.Comment: arXiv admin note: substantial text overlap with arXiv:1903.0650

Key fruit flies species (Diptera, Tephritidae) reported in Africa and presenting a biosecurity concern in Morocco: An Overview

Fruit crop species are from the most widely cultivated crops in Morocco. However, the sustainability of this lucrative business is threatened by infestations of invasive fruit flies (Diptera: Tephritidae) that may inflict heavy economic losses to the country if their invasion occurs. At this time, Medfly is the main fruit fly which causes a high loss and is a phytosanitary concern to fruit species. The distribution and abundance of the major frugivorous tephritids are influenced by host presence, climatic factors, and their potential of invasion. Two types of economic impact of fruit flies are distinguished, direct losses in the yield and indirect losses due to the loss of markets caused by quarantine restrictions imposed by importing countries to prevent the entry of exotic flies in their territory. The most important invasive tephritid fruit flies present in Africa and that may constitute a risk of invasion into Morocco are Bactrocera dorsalis, Bactrocera zonata and Bactrocera cucurbitae. Also, the indigenous species within genera Ceratitis ((Ceratitis quinaria, C. anonae, C. catoirii, C. cosyra, C. silvestrii, C. ditissima, C. fasciventris, C. rosa, C. quilicii) and Dacus (Dacus latifrons, D.vertebratus, D.bivittatus, D.punctatifrons,  Dacus ciliates) may present a risk of introduction to Morocco. These fruit fly species are characterized by having a wide range of host plants and a wide distribution throughout Africa. The risk of spread is enhanced by the lack of control and the weakness of the identification process of the present and newly introduced species. This review presents the status and the distribution of major fruit fly species present in Africa, gives an overview of their host plants, new invasions and means of detection and phytosanitary measures to implement in Morocco to avoid any invasion originated from other African countries. Keywords: Africa, Fruit fly, Distribution, host plant, Invasion, biosecurity, and Morocco

Effect of proximity to Jujube (Ziziphus lotus and Ziziphus jujube) trees on medfly (Ceratitis capitata) populations in citrus orchards of Moulouya Perimeter

Moulouya Perimeter is one of the most important zones of Citrus production in Morocco, with an area of 22.000 ha and 360.000 tons of Citrus production. Medfly “Ceratitis capitata, Wiedemann 1824” is a pest with an important economic impact for Citrus, because of its impact on yield losses and phytosanitary concern linked to its presence. In Citrus orchards of Moulouya perimeter, adjacent wild jujube (Ziziphus lotus and Ziziphus jujuba) trees may have an impact on Medfly populations. The main objective of this study is to evaluate the influence of adjacent jujube trees, growing in windbreaks and noncommercial orchards, on medfly captures in the traps located in citrus orchards and to determine the amount of increase of punctured fruits caused by medfly oviposition considering the distance ranges to the jujube trees (10, 25, 50, 75, 100, 125, 150, 175, 200, 225, 250 and 275m).To achieve this purpose, 180 traps were placed in 15 orchards and monitored for medfly captures weekly, from April to November 2019, within three locations (Aklim, Chouihia, and Reggada) representing Citrus producing area of Moulouya Perimeter. The monitoring of C. capitata adults was conducted using “Maghreb med” traps with trimedlure (tbutyl-4(or5)-chloro-2-methyl-cyclohexane carboxylate) male-specific para-pheromone as attractant and dichlorvos as a toxicant. Five orchards per each location were selected and 12 traps were hung in every orchard in fixed distances from the jujube trees and fruits were checked for punctures. The influence of each jujube tree in citrus orchards in his vicinity is higher within distances inferior to 75 m. Then, its impact could approach 2,25 Ha on average, and in this area, C. capitata population densities were twice to five times as high as in other distances. Furthermore, Citrus trees located at distances inferior to 75m from the jujube trees showed an increase in the percentage of punctured fruits compared with distances higher than 75m

TH-6: a high yielding cultivar of sesame released for general cultivation in Punjab

Background: Sesame (Sesamum indicum L.) is a diploid species, known as Beniseed, Gingelly, Sim-Sim and Til. It is grown in tropical and subtropical areas of the world. Sesame seed contains high nutritional values of certain compounds (25% protein and 50% oil) and is a vital source of natural antioxidants. TH-6 (96006) is characterized by white, bold and high yielding seeded variety of sesame with a unique character of having single stem.Methodology: Variety Punjab Til-90 and line 436602 were cultivated at Oilseeds Research Institute, Faisalabad. At flowering, Til-89 was crossed as female with the line 436602 in 1990. In 1991, the F1 generation of plants were grown and self-pollinated at flowering. Homozygous progenies of pedigree number F6-96006 from F6 were evaluated for their high yield in season 1996-97. Evaluation was done through micro, zonal, station and finally “National Uniform Yield Trials”.Results: In 2006, 2217 kg/ha production was marked as its maximum potential at Oilseed Research Institute (Faisalabad) in Zonal Varietal Trail. In National Uniform Sesame Yield 2006 and 2007 the performance of TH-6 was better than TS-3 (check) by giving 32.16% and 9.59% more yield respectively. TH-6 also showed moderate tolerance against insect pests Phyllody diseases and Charcoal Rot.Conclusion: Agronomic studies revealed that TH-6 performed better if planted in 15th to 30thJune if supplementation of one bag of di-ammonium phosphate (DAP) and half bag of Urea at the time of sowing and flowering, respectively, with 1st and 2nd irrigation

Quality of Hypospadias Surgery in a High Volume Hospital: Review of Short to Medium-Term Outcomes after Snodgrass Hypospadias Repair

OBJECTIVES The study aimed to review short-term and medium-term outcomes of Snodgrass repair from one-year to two-year follow-up. METHODOLOGY It’s a retrospective review of 114 patients (secondary data) with distal penile hypospadias without curvature who underwent Snodgrass repair performed by a single surgeon in the department of Urology, Lady Reading Hospital Peshawar from March 2021 to March 2022. Hypospadias objective score Evaluation (HOSE) was used for functional and cosmetic outcomes. RESULTSThe mean age at the time of presentation for surgery was 3 years. The mean documented follow-up was 13 months (2-23 months). 51% (58) of patients presented with coronal hypospadias, followed by sub-coronal, distal and glanular hypospadias. Overall complication rate was 10%. Three patients developed a total breakdown of their wounds that needed further staged procedures. Meatal stenosis was noted in three patients requiring meatal dilatation, and another two came back with non-obliterative strictures. One had gentle dilatation, and the other underwent an optical urethrotomy. The rest of the four patients developed urethrocutanoeus fistulae (UCF), ultimately getting repaired 6 months postoperatively. Good cosmetic and functional results were achieved in 93% of cases (HOSE score of 14 or above). CONCLUSION This study shows that Snodgrass repair is the best option for mainly correcting distal penile and midshaft hypospadias and has an acceptably low complication rate with better short to medium-term outcomes

Electronic cigarettes use and perception amongst medical students: a cross sectional survey from Sindh, Pakistan

Objective: The manufacturers of electronic cigarettes (e-cigarettes) are actively marketing their product through electronic and social media. Undergraduate medical students are expected to have better knowledge and awareness as they directly interact with patients in their training, The purpose of this study is therefore, to determine knowledge, use and perception regarding e-cigarettes among medical students from Sindh, Pakistan. Results: A cross-sectional study was conducted between 1st July and 30th September 2016 at five different medical colleges situated in the second largest province of Sindh, Pakistan. The data was collected through a structured, self-administered questionnaire. Of the 500 students, the mean age was 21.5 ± 1.7 years and 58% were females. Over (65.6%) students were aware of e-cigarettes, 31 (6.2%) reported having used e-cigarettes, of whom 6 (1.2%) self-reported daily use. Users of conventional tobacco products were significantly more likely to have heard of e-cigarettes (87.6% vs 51.6%, p \u3c 0.001) and having used them (13.9% vs 1.3%, p \u3c 0.001). On multivariable logistic regression analysis we found a strong association of e-cigarette use with consumption of conventional cigarettes [OR: 10.6, 95% CI 3.6-30.8, p \u3c 0.001], use of smokeless tobacco products [OR: 7.9, 95% CI 2.7-23.4, p \u3c 0.001] however a weak association was observed for Shisha use [OR: 3.05, 95% CI 0.9-9.6, p = 0.05]
