Le SIDA en Europe occidentale à travers un regard territorialisé de démographe
Authors: Valdes Béatrice 
Published: June 2022

Le recours à un regard territorialisé de démographe pour l’étude des différences nationales d’incidence et de mortalité du SIDA, dans neuf pays d’Europe occidentale, permet de confirmer certaines spécificités nationales – pas forcément visibles sans rapporter les évènements aux populations susceptibles de les avoir vécus – tout en relativisant certaines autres. Malgré la très forte réduction de l’incidence du SIDA qu’a permis la généralisation du recours aux multithérapies dans tous ces pays depuis le milieu des années 1990, les singularités entre les pays méridionaux et les pays septentrionaux se sont atténuées, mais subsistent encore. En outre, l’utilisation du regard de démographe permet de dégager une interaction entre les différents volets de l’épidémie, à savoir une mise en évidence d’une relation particulière entre une épidémie de SIDA résultant de l’usage de drogues par voie intraveineuse et une épidémie résultant d’une contamination hétérosexuelle du SIDA, notamment dans les pays méridionaux.

Published: June 2022

Combined small cell lung carcinoma (C-SCLC) is rare and accounts for 1-3% of all lung cancer cases. Although its incidence has increased recently, there are limited studies on it. The records of patients admitted to our hospital between January 2015 and December 2019 and diagnosed with histologically proven combined small cell were scanned retrospectively and reviewed. 31 patients were analyzed. The average follow-up time was 10 months. The radiotherapy (RT) rate, surgery rate, and large cell malignancy rate were significantly lower in the ex group than in the living group (p=0.024, p=0.023, p=0.015). The rates of extensive disease, metastasis, and thyroid transcription factor 1 (TTF1) were significantly higher in the old group than in the living group (p=0.000, p=0.000, p=0.029, respectively). In the univariate model, sequential RT, fatigue, lactate dehydrogenase (LDH), stage, metastasis, contralateral lung metastasis, chemotherapy were observed to be significantly effective in predicting survival time (p=0.000, p=0.050, p=0.011, p=0.004, p=0.004, p=0.045, p=0.009). In the multivariate model, independent (p=0.015, p=0.022, p=0.049) efficacy of RT, stage, and chemotherapy in predicting survival was observed. C-SCLC is a specific mixed carcinoma and reports evaluating this type are still scarce. The stage of the disease, radiotherapy and chemotherapy are extremely important in predicting survival.

Objective:
Congenital malformations of the gastrointestinal tract are one of the major causes of neonatal mortality, especially in developing countries. The aim of this study is to assess the overall management of gastrointestinal malformations.

Patients and Methods:
The study design is monocentric and retrospective. It includes all newborns aged 1–28 days with malformations of the gastrointestinal tract between 1st January 2014 and 31st December2018, at the Paediatric Surgery Department of Aristide Le Dantec University Hospital in Dakar. Data were collected by studying patient's records and surgical procedures.

Results:
During the five-year study, 405 newborns with congenital anomalies were admitted to our hospital. A total of 126 newborns were diagnosed with gastrointestinal tract malformations. The incidence was 25.2 cases a year. The sex distribution was 74 boys (58.7%) and 52 girls (41.2%). The mean age at diagnosis was 7.4 ± 3.2 days. Two cases were diagnosed antenatal (1.59%). The mean time to post-natal diagnosis was 6.5 ± 2.1 days. The most common malformation was oesophageal atresia with 43 cases (34.1%). The average time between diagnosis and surgery was 48 h. Out of the 126 cases, 77 (61.1%) received surgery and 49 (38.9%) died before surgery. The main causes of pre-operative death were intricate and dominated by lung infections (42.9%). Among the 77 newborns, who received surgery, 38 (%) had a simple post-operative course, 39 (50.6 %) died. Post-operative deaths were dominated by anaesthetic complications (30.8%), lung infections (46.1%). The overall mortality was 69.8% (n = 88).

Conclusion:
The low socio-economic status, poor pre-natal diagnosis, prematurity, post-natal diagnostic delay, obsolete medical equipment and the lack of neonatal intensive care units were identified as the major factors for high mortality in neonates with gastrointestinal tract malformations in a developing country.

Published: June 2022

Background:
Refractive error (RE) is the most common cause of visual impairment globally and affects about 12.8 million children (5–15 years). Uncorrected RE in children could lead to irreversible vision loss in the paediatric age group. Spectacles are commonly used to correct RE although preferred spectacle design pattern among children may influence spectacle use.

Aims:
This study aims to assess school children's preferred spectacle designs and the factors associated with these preferences in south east Nigeria.

Subjects, Materials and Methods:
A representative cross-sectional study among school children aged 5–15 years in South-East Nigeria. Participants were asked to independently select preferred spectacles displayed based on: frame colour, material, shape of ear-piece, lens size, and shape. Statistical analysis of data to yield frequencies and test of association was done using Chi-square. Binary logistic regression tested the strength of association. Adjusted odds ratios were calculated at 95% confidence interval and P < 0.05 were considered significant.

Results:
The study comprised 5723 school children (males 46.9% and females 53.1%), aged 10.49 ± 2.74 years. Their commonly preferred spectacles were red coloured (35.4%), had straight earpiece (80.6%), of plastic materials (62.8%), rectangular lens shape (55.3%), and medium lens sized (58.6%). Age was the most associated factor with spectacle choice preference among the school children (P < 0.05 in four out of the five possible preferences evaluated).

Conclusions:
Spectacle preferences exist among the study population. Some demographic factors are associated with these preferences which should be considered in any childhood RE services.

AbstractWe prove that torsion codimension
$2$
algebraic cycles modulo rational equivalence on supersingular abelian varieties are algebraically equivalent to zero. As a consequence, we prove that homological equivalence coincides with algebraic equivalence for algebraic cycles of codimension

Difficulties and challenges for admission to the position of schools inspector in Spain and early career development
Authors: Vázquez-Cano Esteban , Campos Barrionuevo Blas 
Published: June 2022

This article presents research that analyzed the most significant needs, difficulties and problems for admission into Spain’s school inspectorates, the expectations of new inspectors and the challenges they face in their assessment of different school settings in the Spanish educational system. Firstly, the research addressed the central questions of school inspection and supervision in the European Union, then a methodology was applied based on virtual ethnography and the reticular-categorical approach to network analysis, with matrix representations and social graphs devised using UCINET and yED Graph Editor visor. This methodological approach was used to analyze the opinions of 140 students between 2017 and 2019 enrolled on the only Masters course in Spain dedicated to schools inspection and supervision, delivered by UNED (Spain’s National Distance Education University). Their open responses to a questionnaire, and course forum interaction, were analyzed from the Social Network Analysis perspective. The results show that the main difficulties, challenges and needs coalesced around four central nodes: the politicization of tribunals and the entrance exam format, the lack of training courses for potential inspectors, the absence of a national study pathway for potential inspectors as an entry requirement, and the need for training in supervision techniques to perform their functions as inspectors.

The soil samples were collected from Jamaratextile Industry,Perundurai, Erode district. The collected samples were subjected to serial dilution and plating technique. The isolated microbial strains were identified based on the morphology, biochemical test and 16s rRNA Sequence. The soil isolates were subjected to textile dye Blue HEGN and Black B degradation based on the decolorizing potential. The most efficient strain was chosen after the immobilization studies. The 16S rRNA sequencing of the most efficient bacterial strain RR4 showed 99% similarity to Bacillus cereus. The analysis of degradation products by FTIR and UV- Vis analysis revealed disruption of dyes linkages and subsequent conversion of aromatic amines into simpler products. Bioremediation has proved to be very effective method in countering the textile dye pollution in an eco-friendly way. This approach creates a promising hope to remediate the environments polluted by textile azo dyes.

Published: June 2022

The rapid development of nanotechnology or nanotoxicology is stimulating research on the potential health hazards and environmental impacts of manufactured nanomaterials (MNMs) and nanoparticles (NPs). This paper focused on the identification of Daphnia pulex from the environment and TiO2 nanoparticles synthesis, characterization and the 24 h acute toxicity of water suspensions of TiO2 NPs to Daphnia pulex, using mortality as toxicological endpoints. The results show that the acute toxicities of 0, 5, 50, 100, 150, 200, 210, 220, 225 and 230 ppm are dose dependent or concentration level. The Lethal Concentration (LC50) values for mortality 24h is observed at 218.79ppm. D. pulex were found to ingest nanoparticles from the test solutions through feeding and their behavioral and morphological effects indicates that the potential ecotoxicological and environmental health of these NPs cannot be ignored.

Groundwater is the most precious gift of nature to living beings, particularly to the mankind and is essential for life. In recent years, rapid development has created an increased demand for drinking water, which is increasingly being fulfilled by groundwater abstraction. The groundwater samples collected from a panjapur area near korai river Tiruchirappalli district Tamil Nadu India. Groundwater samples collected seasonal variation Pre monsoon (May), Monsoon(August), and Post monsoon (November) during the Year 2014. Ten groundwater samples analyzed for major physicochemical parameters such as pH, Electrical Conductivity, Total DissolvedSolids, Total Hardness, Dissolved Oxygen, Biological Oxygen Demand, Chemical Oxygen Demand, Bicarbonate, Calcium,Magnesium, Sodium,Potassium, Sulphate,Chloride and Nitrate, in order to understand the different geochemical processes affecting the groundwater quality. The analytical data were interpreted using WQI. The Calculated WQI value is (101.6). The analytical results indicate the majority of the groundwater samples are unsuitable for drinking purposes. The typical sewage comprising of domestic and other waste is discharged directly into the open land without any proper treatment will cause contamination. This contamination poses serious health impacts in the local residents.The correlation and regression provide an excellent tool for the prediction of parameter values within a reasonable degree of accuracy.

Published: June 2022

Sistem informasi pasar kerja (SIPK) di Indonesia saat ini masih bersifat parsial baik secara kelembagaan maupun fungsinya. Kebijakan yang disusun oleh Kementerian Ketenagakerjaan tidak dapat sepenuhnya diterapkan oleh pemerintah daerah karena berbagai alasan. Hal tersebut berdampak pada lemahnya sistem pendataan ketenagakerjaan di Indonesia. Pada prinsipnya, data ketenagakerjaan memiliki peranan penting dalam perencanaan dan deteksi dini berbagai permasalahan ketenagakerjaan.
Kajian ini bertujuan untuk mengetahui konsep identitas digital ketenagakerjaan (IDK) pada sistem informasi pasar kerja di Indonesia dan sekaligus mengetahui manfaat dari identitas digital ketenagakerjaan tersebut. Metode yang digunakan dalam kajian ini menggunakan analisis deskriptif. Analisis lebih ditekankan pada pemetaan pasar tenaga kerja, integrasi data ketenagakerjaan, dan manfaat dari identitas digital ketenagakerjaan.
Kajian ini menghasilkan konsep IDK yang komprehensif dari hulu ke hilir. Di Hulu, angkatan kerja adalah output dari pendidikan formal sedangkan hilir adalah ketenagakerjaan pasca penempatan. Rangkaian konsep tersebut terintegrasi mengikuti siklus ketenagakerjaan. Angkatan kerja baru output dari dunia pendidikan didata melalui Dapodik dan NIK akan dipantau pergerakan per individu dalam lingkup bisnis proses ketenagakerjaan yang meliputi registrasi dalam pasar kerja, pelatihan dan/atau pemagangan, penempatan (termasuk di dalamnya akses kewirausahaan), selama penempatan, dan pasca penempatan. Siklus itu terus berputar dengan tidak mengesampingkan manfaat bagi masing-masing individu angkatan kerja

Published: June 2022

С развитием компьютерной техники, технологии моделирования и программного обеспечения появляется возможность их широкого применения при аналитических исследованиях химико-технологических процессов. Исследование технологических процессов на компьютерной модели основано на формальной логике, способствующей определению основных влияющих факторов изучаемого объекта. Окончательная дистилляция хлопкового масла относится к процессам перегонки с помощью острого пара, при котором перенос массы происходит между жидкой и паровой фазами. Для составления компьютерной модели технологического процесса разработаны математические описания каждого процесса и подпроцесса. Обобщением получена полная математическая модель процесса окончательной дистилляции мисцеллы хлопкового масла. Разработан алгоритм исследования компьютерной модели процесса, протекающего на новой конструкции трехступенчатого дистиллятора. Компьютерная модель разработана для трехступенчатого аппарата, в котором выходные значения первой ступени будут входными для второй ступени и т.д. По полученным графикам в результате исследования компьютерной модели видно, что в новой конструкции аппарата процесс массопереноса между фазами протекает интенсивнее, а также дает возможность исследования процесса для различных технологических режимов ее введения.
