Revenir d’un terrain n’est jamais anodin. Il y a un avant et un après, celui-ci étant souvent plus difficile à appréhender et analyser. D’où ce dossier consacré au retour après la mission. Cela ne va pas de soi, car le terrain a laissé une empreinte plus ou moins forte et suscite de nombreuses questions en rupture avec la vie ordinaire.
La dissuasion, une fonction globale
Authors: Desportes Vincent
Published: May 2021

Les choix faits pour la défense de la France n’ont pas toujours été opportuns. 1870, 1914 et 1940 sont la résultante d’illusions et d’aveuglements. Or, les évolutions géopolitiques actuelles obligent à revoir notre doctrine basée sur une dissuasion aux concepts vieillissants, sans oublier l’importance du théâtre national.

Des modes de savoir pour affirmer une épistémologie disciplinaire infirmière : des surinterprétations et réductions dans les travaux de Chinn et Kramer
Authors: Vonarx Nicolas
Published: May 2021

L’affirmation d’une discipline académique aux prétentions scientifiques passe par l’élaboration et la diffusion d’un savoir. Prise dans ce projet, la discipline infirmière propose différentes conceptualisations du savoir. Celle de Chinn et Kramer, produite dans la foulée des travaux de Carper, est certainement la plus connue et la plus empruntée pour présenter des fondements épistémologiques de la discipline. Ce texte propose une analyse critique de ces travaux en se concentrant sur les savoirs dits personnels et esthétiques. En détaillant les logiques qui supportent les modes de savoir tels que les définissent les auteures, il met en évidence des surinterprétations et des écarts en regard de la pratique infirmière.

Authors: Kalpana L.D.C.H.N. , Jayasinghe A.B. , Abenayake C.C. , Wijayawardana P.N.P.
Published: May 2021

This study presents a methodology to assess transport network resilience to urban flooding. The proposed methodology is developed based on the centrality measures and graph theory. The study utilises Open-Source GIS tools to compute betweenness and closeness centrality values. The case study was carried out in Greater Colombo - Sri Lanka, with reference to three significant urban flooding events in 2010, 2016, and 2017. The study assessed the resilience of road network in terms of topological impacts and accessibility changes.The results revealed three key findings. First, over 60% of road network revealed a significant change in its topological structural coherence during each flooding event. This was particularly pronounced in vehicular movements relative to pedestrian movements. Second, the study revealed a redundant depreciation of the transport accessibility as it shifted from city centre to peripheral areas creating temporary accessibility hotpots in the periphery. Third, a significant drawback of the resilience of road network was identified in terms of the deviation from the shortest path, increasing the travel time and trip length. In overall, the study concluded that the proposed methodology can be utilised as a planning and designing tool to assess road network`s resilience devising precautionary measures to mitigate disaster risk.
Squamous cell carcinoma of the right renal pelvis in a 46-years-old with long history of right pyelolithiasis. A case report and review of literature
Authors: Salihu Makama Baje , Yusuf Stephen , Ogere Adogu Ibrahim
Published: May 2021

Squamous cell carcinoma of the kidney is a rare malignancy of the upper urothelium usually seen at advanced stage due to delay in diagnosis and or presentation. Mostly seen in patients with history of untreated chronic urolithiasis, chronic renal infection or analgesic abuse. A 46-years-old man who presented with right recurrent loin pain that radiates to the right groin of 10 years duration which worsened 2 weeks prior to presentation, he had history of recent haematuria, right loin pain, significant weight lost with associated history of untreated right renal calculi. General examination was not remarkable, ultrasound scan revealed a huge right renal mass with calculi. Intravenous urogram showed a non-functioning right kidney. Right radical nephrectomy was done, cut surface showed replacement of the renal parenchyma with greyish white tumour with stones in some blind calyxes. Histology revealed moderately differentiated squamous cell carcinoma of the right kidney. We report a case of moderately differentiated squamous cell carcinoma of the right kidney in a patient with a long history of untreated renal calculi. High index of suspicion for malignancy should be kept when seeing patients with long history of untreated renal calculi.
A contribution to the knowledge of Melyridae Dasytinae and Rhadalidae of Cyprus (Coleoptera, Cleroidea)
Authors: Liberti Gianfranco
Published: May 2021

Melyridae Dasytinae and rhadalidae of Cyprus have been studied, based on rather abundant materials from several collections and on the scarce (often obsolete) literature existing. A total of 9 genera and 18 species have been found to live on the Island: photographs or drawings of nearly all of them are provided and a determination key is proposed. Three new species are described: Dasytidius valdelatus n. sp., Dasytiscus anatolicus n. sp. and Aplocnemus (Diplambe) constantini n. sp. Three status changes are proposed, as a necessary anticipation (to be fully justified in a next paper): Dasytidius virescens (baudi di Selve, 1873) and Dasytidius funebris Majer, 1989, previously good species, are considered subspecies of Dasytidius indutus (Kiesenwetter, 1859); Dasytidius similis (Schilsky, 1896), formerly subspecies of D. indutus, is elevated to good species. One new synonymy is proposed: Danacea brevipennis Pic 1932 = Danacea cypria Schilsky, 1897. Dasytes xanthocnemus var. cyprius baudi di Selve, 1873 is not a synonym of Dasytes xanthocnemus Kolenati, 1846 but of Dasytes moniliatus Kiesenwetter, 1863. the variability of 3 species: Dasytes (Mesodasytes) aeneiventris Küster, 1850, Dasytidius inchoatus Majer, 1991 and Aplocnemus (Ischnopalpus) syriacus Schilsky, 1894 is discussed as relevant to their definition. the ♂ of Trichoceble testaceipes Pic, 1921 until now only known through ♀♀, is described. A short distributional analysis, including a rough comparison with the other large Mediterranean island has been attempted.
Torsion of cecal appendix. Report of the first Italian case and review of the literature
Authors: Chiarenza Salvatore Fabio , Costa Lorenzo , Bleve Cosimo
Published: May 2021

In pediatric patients appendicitis is the most common cause of abdominal pain and surgery. Torsion of vermiform appendix is a rare cause, clinically indistinguishable from appendicitis with usually an intraoperative diagnosis. The first description of vermiform appendix torsion was made by Payne in 1918. Clinical presentation is similar to acute appendicitis. Preoperative investigations play a minimal role. Etiology of this condition is unclear, but is possible to distinguish a primary and a secondary torsion. We report a case of 5-years-old boy who presented with right lower quadrant abdominal pain. His clinical signs, symptoms and investigations mimicked an acute appendicitis. Intraoperatively we found a 720° appendix torsion on its base with its mesentery rotated in counter-clockwise direction. The appendix was gangrenous in appearance. A video-assisted trans-umbilical appendectomy was performed. We describe clinical presentation and management of this rare condition reviewing the literature.
Biomarkers of myocardial injury in lupus nephritis
Authors: Ibrahim Mohammed E.-T. , EIshahawy El Metwally L. , Mahmoud Ashraf T. , Nasr Rehab S. , Mansour Ahmed E.
Published: May 2021

Background

Cardiovascular disease (CVD) is the main cause of death in patients with systemic lupus erythematosus (SLE) and lupus nephritis (LN). This study aimed to evaluate the prevalence of myocardial injury among patients with SLE without nephritis and patients with LN, determine whether serum high-sensitivity cardiac troponin T and creatine phosphokinase-MB (CKMB) might help to identify patients with LN at risk for CVD, and identify LN as a risk factor for myocardial injury.

Patients and methods

This study was conducted on 50 patients (30 patients with LN and 20 patients with SLE without nephritis). The SLE disease activity index (SLEDAI) and Systemic Lupus International Collaborating Clinics Damage Index (SLICC/DI) were assessed. Laboratory investigations, cardiac enzymes (Hs-TnT and CKMB), and transthoracic echocardiography were performed.

Results

The results demonstrated a higher prevalence of CVD in patients with LN. A total of 28 patients with LN (93.3%) vs 10 patients with SLE (50%) had detectable high-sensitivity troponin (Hs-TnT) levels, with a mean 29.77±18.22 vs 7.2±6.21 ng/l, respectively. The mean value of CKMB was higher in patients with LN than patients with SLE (23.9±18.6 vs 14.8±9.4 μg/l, respectively). Multilinear regression analysis for Hs-TnT revealed that low estimated glomerular filtration rate, high urinary albumin-to-creatinine ratio, low ejection fraction, and different ECHO diameters were the most statistically significant predictors of troponin elevation, with a P value less than 0.05. The strongest renal predictors of CKMB were estimated glomerular filtration rate and proteinuria, with a P value less than 0.05.

Conclusion

CVD is more in patients with LN than patients with SLE. Hs-TnT levels is a signature of subclinical cardiac disease, which could be used to identify at-risk individuals. CKMB and echocardiography lack adequate sensitivity for the diagnosis of myocardial injury in patients with LN.

Published: May 2021

Context:

Diagnostic reference level (DRL) is the first step in the optimization process to manage patient dose corresponding with the medical purpose.

Aim:

The objective of this study was to develop local DRL for computed tomography (CT) of the head and abdomen in adult patients in four CT centers in South-South Nigeria.

Materials and Methods:

A prospective, cross-sectional study of 546 adult patients that underwent CT examination of the head and abdomen from 2018 to 2020 using four different CT scanners. Volume CT dose index (CTDIvol) and dose length product (DLP) of contrast and non-contrast CT examinations of the head and abdomen were collated and the 50th percentile DRL was determined and compared to other published DRLs.

Results:

The 50th percentile CTDIvol/DLP for non-contrast head CT examination for centers A, B, C, and D was 75.3 mGy/1776.6 mGy.cm, 21.8 mGy/457 mGy.cm, 17.4 mGy/373.6 mGy.cm, and 29.6 mGy/628.5 mGy.cm, respectively. The 50th percentile CTDIvol/DLP for contrast head CT examination for centers A, B, C, and D was 150.6 mGy/3326.2 mGy.cm, 41.4 mGy/832.4 mGy.cm, 35.6 mGy/653.6 mGy.cm, and 77.9 mGy/1458.4 mGy.cm, respectively. The 50th percentile CTDIvol/DLP for non-contrast abdomen CT examination for centers A and B was 22.8 mGy/1488.5 mGy.cm and 7.9 mGy/302.3 mGy.cm, respectively. The 50th percentile CTDIvol/DLP for contrast abdomen CT examination for centers B and C was 19.6 mGy/825.7 mGy.cm and 31.5 mGy/1555.5 mGy.cm, respectively. There was correlation between contrast and non-contrast CTDI (P = 0.003) and DLP (P = 0.025) for the head.

Conclusion:

Wide variations CTDIvol and DLP values were observed among the centers for similar body part CT examinations.
Hairer’s reconstruction theorem without regularity structures
Authors: Caravenna Francesco , Zambotti Lorenzo
Published: May 2021

This survey is devoted to Martin Hairer’s Reconstruction Theorem, which is one of the cornerstones of his theory of Regularity Structures [6]. Our aim is to give a new self-contained and elementary proof of this theorem, together with some applications, including a characterization, based on a single arbitrary test function, of negative Hölder spaces. We present the Reconstruction Theorem as a general result in the theory of distributions that can be understood without any knowledge of Regularity Structures themselves, which we do not even need to define.
Prevalence of otitis media in children attending a Primary Health Care Center in Samaru, Zaria, Nigeria
Authors: Atta H.I. , Umar F.F.
Published: May 2021

Otitis media is an inflammatory disease of the mucosal lining of the middle ear. It occurs more frequently in children due to the shorter and more horizontal eustachian tube in their ears. The focus of this study is determining the prevalence of otitis media in children aged 6 months – 10 years attending a primary health care facility in Samaru, Zaria, Nigeria. Fifty swabs from ear discharge and imparted wax were obtained from the study subjects regardless of whether they were presenting with symptoms of otitis media or not. Information on certain symptoms, as well as demographic and risk factors was obtained through the use of questionnaires. A prevalence of 54% of otitis media was obtained in this study. The following bacterial species were isolated: Pseudomonas aeruginosa (25.7%), Escherichia coli (25.7%), Klebsiella pneumoniae (14.3%), Staphylococcus aureus (14.3%), Proteus mirabilis (8.6%), Coagulase negative Staphylococci (8.6%) and Proteus vulgaris (3.7%). The infection was observed to be higher in children in the age range, six months to two years. Risk factors such as the use of cotton buds in cleaning the ear, posture of the child during breast-feeding and not being exclusively breast-fed were shown to be very prominent among the children studied. Antibiotic susceptibility tests revealed that among the Gram negative bacteria isolated, Pseudomonas aeruginosa and Klebsiella pneumoniae were resistant to more than two antibiotics. Coagulase negative Staphylococcus was resistant to all the antibiotics except Ceftriaxone, Streptomycin and Cefuroxime. On the other hand, Staphylococcus aureus was susceptible to all the antibiotics tested with the exception of Cefuroxime, Ceftriaxone and Ampiclox. Therefore, it is recommended that antibiotic susceptibility testing be conducted before treatment of otitis media in children. The importance of exclusive breast-feeding and good personal hygiene should be emphasized to nursing mothers.

Published: May 2021

In this study, copper nanoparticle (CuNPs) was synthesized using green technology and the CuNPs was characterized with Energy Dispersive X-ray (EDX) which confirmed the presence of copper. Scanning Electron Microscopy (SEM) showed the morphology and the average size was calculated to be 2.47 ± 1 nm. The functional groups were identified by Fourier transform infrared spectroscopy (FTIR) and this revealed that OH functional group was anchored on the surface of the nanoparticles. Antimicrobial activity of the synthesizedCuNPs was investigated at varying concentrations (0.25, 0.5, 1, 2, 3, 4, 5, 6 and 7 mg/ml) dissolved in 100% dimethyl sulfoxide (DMSO). It was tested against five food borne pathogenic organisms: Salmonella typhimurium, Methicillin resistant Staphylococcus aureus  (MRSA), Enterococcus faecalis, Shigella flexneri, and Acinetobacter baumannii using the Kirby Bauer disc diffusion and agar well   method. The results showed that the antimicrobial zone of inhibition increased with an increase in concentration of the CuNPs, an  average diameter of 25 mm at 7 mg/ml, 22 mm at 5 mg/ml and an average diameter of 13 mm at 2 mg/ml of 100% DMSO.  Nanoparticles at 0.25 mg/ml and 0.5 mg/ml concentration failed to produce any clear zone across all the test organisms while only Enterococcus faecalis was sensitive with a clear zone diameter of 10 mm at 1 mg/ml CuNPs. MRSA has the least susceptibility: 9 mm clear zone diameter at 2 mg/ml and at 7 mg/ml clear zone diameter of 20 mm, relative to other tested organisms. The test organisms were not sensitive to the following conventional antibiotics: Cefuroxime, Ceftazidime, Erythromycin, Amoxicillin/Clavulanic acid and Cloxacillin, but only sensitive to Gentamicin, Ceftriaxone and Ofloxacin. MRSA on the other hand was not sensitive to all the eight antibiotics tested but susceptible to the CuNPs. The results obtained from this study indicated that copper nanoparticles can be used in the food industry to control both Gram positive and negative bacteria tested.

Germination and seedling growth in Afzelia africana Sm. ex. Pers.
Authors: Ogbimi E.R. , Sakpere A.M.A.
Published: May 2021

This study determined the best pre–treatment regime required for germination of the seeds of Afzelia africana Sm.Ex.Pers. and also provided information on the early growth parameters of the plant seedlings. Seeds of A. africana were collected from Obafemi Awolowo University, Ile – Ife (Lat 7° 32'N, Long 4° 31'E) and authenticated at the IFE-herbarium. One hundred and twenty five (125) seeds were sown per treatment (n=5 with 5 replicates and 5 repeats). Five (5) seeds each were sown in small petri dishes, without pre–treatment (control), or treated by subjecting to mechanical scarification and chemical scarification using Tetraoxosulphate (VI) acid (H SO ) and Trioxonitrate (V) acid (HNO3 ) for germination studies. Germination counts were made  at an interval of 2 days. For the six different pre–treatments, five seedlings per plastic bowl were transferred into soil in a total of twenty plastic bowls laid out in a randomized design and their growth monitored for 40 weeks. Results showed that pre–treatment of seeds with mechanical  scarification gave the highest percentage germination. Significant differences (P ˂ 0.05) occurred in the shoot height and in the number of leaves between 4 and 12 weeks of growth. The study established that pre–treatment with mechanical scarification was the best for uniform germination of seeds of the plant. This study has provided alternative means of pretreating A. africana seeds apart from using H2SO4 – the first to subject seeds to mechanical scarification and 2 4 chemical scarification using HNO3 , in addition to providing information on the germination parameters and the seedling growth rate of Afzelia africana.

Hepatitis E Virus Immunoglobulin M (IgM) and associated risk factors in southwest, Nigeria
Authors: Adesina O.A. , Shodunke O.C. , Adedara O.O. , Oluyege A.O.
Published: May 2021

Hepatitis E is one of the most frequent causes of acute hepatitis worldwide, with an estimated 20 million infections and 70,000 deaths attributed to hepatitis E virus (HEV) genotypes 1 and 2 every year. This study was designed to determine the prevalence of HEV immunoglobulin M (IgM) in southwest (SW) Nigeria. Venous blood samples totalling 359 were collected from pregnant women on routine check, apparently healthy prospective blood donors and sick individuals presenting with fever and abdominal disturbance from health facilities in Ekiti, Lagos, Osun and Oyo states, of Nigeria. A structured questionnaire form was administered to gather socio-demographic data, health and travel history from each consenting participant. The screening for HEV IgM was done using HEV IgM ELISA kit. Statistical analyses, including descriptive analysis, correlations and binary logistic regression were carried out using SPSS version 21. In all, 131 samples (36.5%) tested positive for HEV IgM. Osun state had the highest occurrence of HEV IgM (n = 49; 13.6%,) while Ekiti had the least (n= 22; 6.1%). Apparently healthy participants with detectable HEV IgM were 52 (14.5%) while pregnant womenwere 51 (14.2%). Risk factors implicated in this study were flooding and injection drug use. The overall HEV prevalence reported in this study was higher than previous reports in Nigeria . Higher HEV prevalence in this study could be due to a larger coverage area in the country as well as detection of ongoing infection. The detection of HEV IgM in pregnant women and apparently healthy prospective blood donors indicated ongoing infection with risk of spread to susceptibles since HEV is neither routinely screened for among pregnant women nor among prospective blood donors.

Characterization of magnetic field horizontal component in selected stations along the 210o MM
Authors: Idowu A. , Adimula A.
Published: May 2021

Characterizing the magnetic field horizontal component (H) variability helps to better accommodate the irregular fluctuations inthe electron/ion density of the ionosphere for mitigating short-wave radio communication and Global Navigation Satellite Systems (GNSS) disruptions. This study employed three year data (2007-2009) from Magnetic Data Acquisition System (MAGDAS) facilities at six (6) observatories along the 210o magnetic meridian (MM) for investigating hourly, seasonal and annual variations in the horizontal  component of the Earth’s magnetic field. The baseline value of H was computed from its average value near local midnight hours between 2400 and 0100 local time (LT) and subtracted from other hours value for the hourly variation; while the monthly and annual averages were computed for seasonal and yearly analysis respectively. Results indicates that maximum values of Sq are recorded in equinoctial season with an annual peak value of 70.96 nT for year 2009 recorded at Langkawi (LKW) as against the lowest peak value of 27.45 nT recorded in Cooktown (CKT) at 1300LT.

Criteria for Appointment of Members to University Councils in Polish Public HEIs: Management Professionalization in the Polish Academia
Authors: Milewska Ewelina
Published: May 2021

Background. For many years, the Polish style of managing universities was based on the Humboldtian model of higher education and the assumption of academic self-government that decides in a collegial manner. Simultaneously, “Ustawa 2.0” (The Law on Higher Education and Science of 20 July 2018) significantly changed the way of managing universities. The state authorities noticed that the hermetic academic environment must become open toward the socioeconomic sphere, cooperate with it, and enable universities to professionalize their management.

Research aims. This article seeks to learn the criteria of appointing members to university councils in Poland from the perspective of Ustawa 2.0 and those people who were directly or indirectly engaged in choosing the councils’ members. In the light of this goal, I had to capture the solutions introduced by Ustawa 2.0 from the perspective of changes that occurred in the university management in Poland.

Methodology. I used a mixed methodology to conduct this study. To that end, I analyzed the contents of Ustawa 2.0 and particularly focused on articles about appointing members to the councils. Additionally, I analyzed twenty statutes of Polish universities singled out by the Ministry of Science and Higher Education in the first edition of the competition “Excellence Initiative – Research University.” Moreover, I interviewed seven people in university management positions who were engaged in appointing members to university councils (among others, a rector and a vice-rector).

Findings. Although university councils operate in many countries, they are a novelty in the structures of the higher education institution (HEI) management system in Poland. The role and competencies of the councils are broad, and they practically influence how Polish universities operate. The conducted research showed that the appointment of members to the university councils follows the universal rules specified in the Ustawa 2.0 and, partially, in the statutes of universities. The law indicates that university council members should be persons respected in the academic environment, who know the mission and values of a given university.

Rong biển thường được sử dụng làm thức ăn, làm thành phần chính trong thực phẩm chức năng, mỹ phẩm và làm phân bón. Dịch chiết từ rong biển có thể được sử dụng làm phân bón qua lá cho các loại cây trồng. Rong mứt (Porphyra vietnamensis) tươi được chế biến sơ bộ gồm rửa cát, rác, phơi khô và nghiền nhỏ trước khi chiết. Trộn rong biển đã qua xử lý với dung môi theo tỷ lệ 0,5 g : 25 ml. Các loại dung môi sử dụng HCl, H2SO4, NaOH và KOH; thời gian chiết từ 1 – 11 giờ, nhiệt độ chiết 28, 55 và 95oC. Kết quả nghiên cứu cho thấy hàm lượng protein trong dịch chiết sử dụng các dung môi NaOH hay KOH cao hơn 5 – 6 lần so với chiết bằng dung môi HCl, H2SO4. Tăng nhiệt độ hay tăng thời gian chiết đều làm tăng hàm lượng protein trong dịch chiết. Khi sử dụng dung môi KOH 5% thì chiết ở nhiệt độ 95oC có hàm lượng protein trong dịch chiết cao gấp 2,3 – 3,6 lần so với chiết ở nhiệt độ 28 hay 55oC. Đối với chiết bằng KOH thì thời gian chiết thích hợp là khoảng 9 giờ ở nhiệt độ khoảng 100oC. Thêm vào đó, chiết rong biển bằng KOH cho hàm lượng N tổng số và K2O tổng số cao hơn chiết bằng H2SO4. Việc lựa chọn nồng độ KOH thích hợp cần dựa vào nhu cầu của loại cây trồng và thời kỳ sinh trưởng và phát triển của chúng. Kali hiđroxit là dung môi rất tiềm năng trong việc chiết rong biển làm phân bón lá vì nó vừa cung cấp dinh dưỡng đa lượng Kali vừa làm tăng chất lượng dịch chiết.

Trong nghiên cứu này, chúng tôi tiến hành phân tích tính chất cảm quan của sản phẩm hành tím đến từ vùng nguyên liệu khác nhau như Tiền Giang, Lý Sơn, Vĩnh Châu, Ninh Thuận. Kết quả phân tích cảm quan được thực hiện trên hội đồng gồm 9 người được lựa chọn và huấn luyện. Phương pháp thành phần chính (PCA) được sử dụng để phân tích dữ liệu. Kết quả cho thấy nguyên liệu hành tím từ Vùng Vĩnh Châu có những đặc thù về tính chất cảm quan như  “màu tím”, “mùi thơm hành tím”, “độ giòn”, “vị ngọt”, “hậu vị ngọt”, “độ ẩm bề mặt cắt”, “vân ngang đều” và “hình dạng tròn”; trong khi đó hành tím vùng Lý Sơn, Ninh Thuận có đặc điểm khác như  “độ dai”, “hình dạng dài”, “vị đắng” và “hậu vị đắng”. Kết quả nghiên cứu có ý nghĩa trong việc xây dựng danh mục thuật ngữ về đánh giá cảm quan hành tím, là tài liệu khoa học cảm quan có giá trị tham khảo quan trọng cho nhà nghiên cứu, sản xuất, kinh doanh… sản phẩm hành tím. Dữ liệu từ nghiên cứu này là cơ sở xác định đặc thù của sản phẩm hành tím Vĩnh Châu với các sản phẩm hành tím ở khu vực khác ở Việt Nam.

CULTURAL DIMENSIONS OF ENVIRONMENTAL PROBLEMS: A CRITICAL OVERVIEW OF SOLID WASTE GENERATION AND MANAGEMENT IN NIGERIA
Authors: Albert Ajani Oludele , Olutayo Fakunle Sunday
Published: May 2021

Several studies have presented solid waste generation and management in urban centres as an engineering and technological concern. These studies neglected culture as the basic determinants of all happenings in human society; hence, the cultural facets of solid waste generation and management were rendered insignificant. As culture provides the context within which all human activities take place, culture was envisaged in this paper as a driving force for public perception, decision making and participation in solid waste generation and management in urban centres. Therefore, this study adopted both meta-analysis and meta-synthesis to pinpoint and discuss some theoretical key cultural factors and social practices influencing municipal solid waste generation and management. It identified trends and relationship between findings from the available empirical and theoretical studies. This paper discovered in the available relevant literature that cultural factors such as customs, belief and attitude of the urbanites that promoted their preference for food packaged with non-biodegradable material and the ways they conducted social practices resulted in solid waste generation. Lastly, methods and the cost of solid waste disposal, individualism and nonchalant attitude of people were found as the factors militating against proper management of solid wastes.

As Parcerias Público-Privadas são definidas pela Lei 11.079 define PPP como contrato de concessão seja na modalidade patrocinada ou administrativa, com distintas formas de remuneração. Em razão das limitações orçamentarias, agravadas pela COVID-19 e a perda de arrecadação pelos entes da federação, converge para agravar o déficit de infraestrutura, tais como, rodovias, portos e aeroportos, bem como agrava o déficit na prestação dos serviços públicos ou implementação de direitos sociais, dentre eles, o direito fundamental a saúde, educação, moradia, transporte, saneamento e tratamento adequado dos resíduos. Daí a importância do conhecimento das vantagens e características das PPP's pelo intérprete, especialmente em razão das peculiaridades, notadamente caracterizada pela multidisciplinaridade, por ensejar abordagens fiscal, jurídica, ambiental, engenharia, dentre outras analises, tais como abordagem da viabilidade e modelagem. Diante desse cenário, valendo-se do método dedutivo, além da utilização de dados estatísticos fornecidos pelo tesouro direto, buscou a pesquisa analisar esse sofisticado instrumento.
A Tribunalização do Poder Político:
Authors: Sirena Hugo
Published: May 2021

O presente artigo busca, em essência, explorar um fenômeno crescente nas democracias ocidentais, especialmente na experiência brasileira: o franco deslocamento do debate político para o âmbito judicial. De fato, vislumbra-se – especialmente no Brasil, mas não apenas nele – uma clara tendência de judicialização das questões (eminentemente) políticas, ocasionando uma verdadeira inflação do Poder Judiciário (tanto no sentido de um aumento no alcance de sua atuação quanto, também, no de relevância do seu papel na decisão dos rumos políticos do país). Para tanto, porém, este estudo diagnostica a necessidade de se promover, de maneira prévia, uma incursão histórica – datada, espacialmente restrita e metodologicamente limitada – pela passagem de um constitucionalismo liberal para um constitucionalismo eminentemente social, desvelando a crise pela qual esse modelo de democracia de massa passa até se alcançar o atual contexto vigente. Dentro dessa perspectiva, parece imprescindível dialogar com os clássicos, resgatando – na origem – a questão da tripartição de poderes e de que forma este princípio fundante dos regimes democráticos é reformulado na atual conjuntura. Ao final, apresentam-se algumas conclusões, sob a ótica de julgados exarados pelas Cortes nacionais – notadamente, o Superior Tribunal de Justiça e o Supremo Tribunal Federal –, acerca do posicionamento judicial forjado sobre questões eminentemente políticas.
TRAVAILLER DANS L'ÉDUCATION AVEC LA COMPRÉHENSION DES CONCEPTS DES SCIENCES / WORKING IN EDUCATION WITH UNDERSTANDING THE CONCEPTS OF SCIENCE
Authors: Rodriguez James
Published: May 2021

Cet article aborde la question des cadres théoriques plus larges pour l'enseignement des sciences physiques et naturelles. Trois approches distinctes mais complémentaires sont discutées à cet égard : des approches didactiques influencées par les courants psychologiques pour l'apprentissage, des approches orientées à l’enseignement et une troisième tendance plus traditionnelle adaptées aux objets du savoir savant.

This article addresses the issue of broader theoretical frameworks for the teaching of the physical and natural sciences. Three distinct but complementary approaches are discussed in this regard: educational approaches influenced by psychological currents for learning, teaching-oriented approaches and a third, more traditional trend adapted to the objects of scholarly knowledge.

Non-traumatic epidural posterior fossa hematomas in child with Sensenbrenner syndrome: a case report and literature review
Authors: Guimarães Mariana Mazzuia , Cardeal Daniel Dante , Lucio José Erasmo Dal Col , Sanders Felipe Hada , Lordelo Gustavo Correa , Teixeira Manoel Jacobsen , Matushita Hamilton
Published: May 2021

Background: Posterior fossa extradural hematomas are an uncommon condition with more than half of cases appearing in the pediatric population. Although the majority of cases are caused by substantial trauma, it may also be related to systemic diseases and bleeding disorders without the history of head trauma.
Case report: We present the case of a 6-year-old female affected by Sensenbrenner syndrome with a non-traumatic subacute posterior fossa epidural hematoma. The patient was surgically treated and medically discharged without further neurological alteration. This is the first report of spontaneous cerebral hematoma associated with this syndrome in the literature. A literature review of the main aspects of both topics was performed.
Conclusions: Although spontaneous posterior fossa epidural hematomas are rare, clinicians should be aware and highly suspicious of this differential diagnosis in certain situations such as coagulopathies and other specific systemic diseases, as fast recognition and assertive treatment are important for better outcomes.

Patients and Methods: Two cases of the peritoneal catheter extrusion through the abdominal wall are reported in patients with congenital hydrocephalus.
Results: Were discovered after removal of the bypass system and systemic antibiotic therapy, followed by replacement of new bypass, with excellent results.
Conclusion: In the presence of this complication, surgical treatment is indicated, through complete removal of the system, systemic antibiotic therapy and subsequent replacement of a new system.
Mental readiness: focusing on the cutting edge
Authors: McDonald Judy M
Published: May 2021

Several intriguing questions were raised during my presentation on Mental readiness and pediatric neurosurgery at the Brazil Society for Pediatric Neurosurgery (BSPN) Scientific Meeting–Webinar on April 15, 2020. Does arrogance disturb mental readiness techniques? Can mindfulness techniques improve surgical readiness? Can simulation models improve mindfulness? How do you stay focused on routine procedures you’ve done 800 times? The University of Ottawa (Canada)—where I am a research scientist in at the McLaughlin Centre for Population Health Risk Assessment in the Faculty of Medicine—has conducted extensive studies on a new discipline called operational readiness. It correlates research with the performances of Olympic athletes and people in high-risk occupations, like surgeons, air traffic controllers and police, whose standards of excellence have life-and-death consequences. So, what can we learn from the best in these fields? Plenty. Our ongoing work makes it clear that effective focusing practices impact one’s performance. But, it is not always easy to “be there for the task-at-hand with all your attention on the right things for the duration of the event without distracting thoughts.” Here are five focusing techniques used by elite surgeons and other peak performers compiled by researchers at the University of Ottawa.

“To awaken the people, it is women who must be awakened, once she is in the moves, the family moves, the villages’ moves, and nation moves”. Pt. Jawaharlal Nehru Introduction: Women empowerment is gaining popularity in the 20th century; it is era of socio- cultural reforms. Empowerment means to increase political, social, educational, and economic, Gender or spiritual strength of personal society. Women constitute the most elegant resource of society. They are regarded as the backbone in family. They play the role of mother, sister, wife, grandmother. Women are considered as the central pillar of every sphere of development in human progress. A woman is regarded as agent of for the growth and development of family as well as good society. In rural areas women are closely attached with the environment for the survival and livelihood. Protection and conservation of the forest is correlated with the role of women. In remote areas women not runs the family they also tries to earn additional wages for their family. It is very much peculiar and unique system that in Galo and some others tribes of Arunachal Pradesh women work harder than the male. They are more in cultivation than male counter parts. So if they are empowered economically, as well as socio-politically, the scenario of the rural areas will definitely transform towards the path of prosperity. For further up-liftment of the women status. International women year was declared in 1975 by United Nation. The 08th march of every year is celebrated as International women Days. The first international conference on women was held in Mexico City in1975. Followed by, Copenhagen in199 and third conference in Nairobi 1985.

Several studies on the disappearance and monitoring of natural resource dynamics on a global scale show a general trend towards the disappearance of natural areas. Protected areas are not immune to this scourge. Thus, this study attempts to analyze the management of protected areas in Côte d’ Ivoire through the Kani-red Bandama classified forest. Overall, the study aims to assess the impact of human practices on the resources of this classified forest. As activities, the aim is to characterize the dynamics of land use in the classified forest and to determine the factors of these dynamics. The study is based on satellite images (Landsat 5 TM, Landsat 7 ETM+ and Landsat 8 OLI/TIRS) from 1986, 2001 and 2016, cartographic and socio-demographic data, and field observations. The preferred tools for data processing and analysis are remote sensing and GIS. The results show that natural areas under the effect of human actions are undergoing very advanced degradation. In 15 years, natural areas have given way to agricultural areas which have increased from 1% to more than 30% with an intensification of cashew nut cultivation resulting in the multiplication of cashew nut orchards. The classified forest of Kani red Bandama is under the influence of human activities reflected by the infiltration of agricultural settlers and breeders whose opposing uses of natural resources lead to conflicts.
