Published: June 2020

Commercially packaged water has been the main source of water supply to residents of Ado Metropolis; due to lack of potable water supply, individuals depend on commercial packaged water for drinking and domestic use. As a result of this, one has little or no assurance on the quality and safety of the water and its source. Heavy metal contamination includes exposure to lead, mercury, arsenic and cadmium, heavy metal contamination in Ado metropolis includes anthropogenic sources which includes activities of mining industries as discharge their untreated effluents into nearby water sources, other source of contamination includes automobile source that releases zinc, arsenic and copper; insecticides which releases arsenic and burning of fossil fuels which releases nickel, vanadium and mercury. Heavy metals cause general body weakness, abdominal pain, shortness of breath, chills, diarrhea, vomiting and tingling in the hands and feet when consumed. Hence, this study is important because it will reveal the presence of heavy metals in sampled waters in Ado Metropolis and also compare with WHO standard which in turn gives room for the suggestion of mitigating measures to regulate the sale of these public waters. Some brands of commercially packaged were purchased from different markets in Ado metropolis based on accessibility and high demands.

Authors: Ingle Sumedh , Deshmukh M. J.
Published: June 2020

The primary objective of the existing work is to evaluate hot gas welding technique for PP composite material and carrying out analysis over the critical parameters (air flow rate, temperature, weld time) to determine material weld strength in tensile conditions. Polypropylene blend with elastomer have wide application in engineering areas due to their desired properties but due to these changed properties over existing one recycling get affected and became difficult so their reparability should be considered. Hot gas welding helps to join the cracks and restore defects in it. Extracting the optimized values from critical parameters will help to make the method more efficient and effective. Tensile probing carried over specimen by considering ASTM standards assist to know former and later tensile conditions of welded joints.

De la norme à la pratique écocitoyenne
Authors: Ginsburger Maël
Published: June 2020

Depuis les années 1990, la multiplication des politiques de sensibilisation à la protection de l'environnement a contribué à faire émerger une « norme d'écocitoyenneté ». Conscient de la nécessité d'agir individuellement pour protéger l'environnement, l'écocitoyen modifierait ses pratiques domestiques et de consommation pour les rendre plus durables. À partir des données de l'« Enquête sur les pratiques environnementales des ménages » (« EPEM ») 2016 (CGDD/SDES), cet article étudie l'ampleur et la nature de l'appropriation dont cette norme a fait l'objet dans la population française. La diffusion des attitudes et des pratiques valorisées ne s'opère pas de manière homogène, les individus préoccupés par l'environnement ne modifiant pas l'ensemble de leur mode de vie. Le rapport quotidien à l'écologie apparait plutôt dual, l'écologie du geste ­ celle des pratiques au c ur des campagnes de sensibilisation ­ se distinguant d'une écologie de la frugalité ­ qui traduit avant tout une faible intégration à la société de consommation. Minoritaires, certaines configurations de pratiques et d'attitudes associent néanmoins ces deux formes d'écologie, suggérant l'existence ­ ou l'émergence ­ d'un habitus écologique non seulement au sein d'urbains très diplômés, mais aussi d'une population plus modeste, féminine et vivant seule.
Technical Efficiency and Productivity of Public District Hospitals in Kwazulu-Natal Province, South Africa
Authors: Babalola Tesleem K. , Moodley Indres
Published: June 2020

Background

District hospitals (DHs) constitute a significant proportion of public hospitals and consume a more substantial percentage of the government's total hospital budget. With the level of resources disbursed to DHs, it is essential to ensure efficient allocation and utilization. Hence, this study set out to assess the technical efficiency and productivity of public DHs in KwaZulu- Natal province, South Africa.

Methods

Data envelopment analysis (DEA) and Malmquist total factor productivity (MTFP) were used to assess technical efficiency, identify adjustments required to make inefficient facilities more efficient, and determine overall productivity growth. Input data such as medical personnel and output information such as outpatient visits were retrieved from the databases of the district health information system (DHIS), and personnel salary systems (PERSAL) for three consecutive financial years (2014/15, 2015/16 and 2016/17). A total of 38 district hospitals were included in the study.

Results

The proportion of technically efficient facilities according to constant return to scale (CRS) were 12 (31.6%), 16 (42.1%) and 14 (36.8%) in 2014/15, 2015/16 and 2016/17 respectively while according to the variable return to scale (VRS) technically efficient facilities were 22 (57.9%), 19 (50.0) and 21 (55.2%) respectively for the three consecutive years. On average, the total productivity of DHs increased by 4.8 percent over the three years, which is attributed majorly to technical growth of 6.9 percent.

Conclusion

This study showed that a significant proportion of the district hospitals were technically inefficiency. Also, steps that could enable more efficient use of healthcare resources to yield optimal health service delivery were recommended.
A Five-Year (2015 to 2019) Analysis of Studies Focused on Breast Cancer Prediction Using Machine Learning: A Systematic Review and Bibliometric Analysis
Authors: Salod Zakia , Singh Yashik
Published: June 2020

The objective 1 of this study was to investigate trends in breast cancer (BC) prediction using machine learning (ML) publications by analysing country, first author, journal, institutional collaborations and co-occurrence of author keywords. The objective 2 was to provide a review of studies on BC prediction using ML and a blood analysis dataset (Breast Cancer Coimbra Dataset [BCCD]), and the objective 3 was to provide a brief review of studies based on BC prediction using ML and patients’ fine needle aspirate cytology data (Wisconsin Breast Cancer Dataset [WBCD]). The design of this study was as follows: for objective 1: bibliometric analysis, data source PubMed (2015-2019); for objective 2: systematic review, data source: Google and Google Scholar (2018-2019); for objective 3: systematic review, data source: Google Scholar (2016-2019). The inclusion criteria for objective 1 were all publication results yielded from the searches. All English papers that had a ‘PDF’ option from the search results were included for objective 2. A sample of the ‘PDF’ English papers were included for objective 3. All 116 female patients from the BCCD, consisting of 64 positive BC patients and 52 controls were included in the study for objective 2. For the WBCD, all 699 female patients comprising of 458 with a benign BC tumour and 241 with a malignant BC tumour were included for objective 3. All 2928 publications were included for objective 1. The results showed that the United States of America (USA) produced the highest number of publications (n=803). In total, 2419 first authors contributed towards the publications. Breast Cancer Research and Treatment was the highest ranked journal. Institutional collaborations mainly occurred within the USA. The use of ML for BC screening and detection was the most researched topic. A total of 19 distinct papers were included for objectives 2 and 3. The findings from these studies were never presented to clinicians for validations. In conclusion, the use of ML for BC screening and detection is promising.
MATERIALI CON BAGNABILITÃ€ CONTROLLATA. UNâ€™ISPIRAZIONE DALLA NATURA
Authors: Ardizzone Silvia , Meroni Daniela
Published: June 2020

The wettability of solid surfaces is the result of the balance between adhesive and cohesive forces. When adhesive forces at the solid/liquid interface prevail over the cohesive forces in the liquid, the drops will spread over the solid leading to a good wetting as in the case of water over an hydrophilic surface. When instead the adhesive forces are weak, the liquid will not wet the surface remaining in droplets, as water on a polymer. Natural materials exhibit tailored wetting behavior: for instance, certain leaves and insects present superhydrophobic properties. By mimicking what nature creates in an exemplary way, the wetting properties of systems can be tailored experimentally to obtain materials with great applicative impact. The possible applications of such phenomena are very numerous and span from biomaterials to antistain materials, from antifog surfaces to systems for the protection of cultural heritage.

ITALIAN GEOLOGY AND CLIMATE CHANGE IN THE DEEP PAST
Authors: Jenkyns Hugh C.
Published: June 2020

Mesozoic sedimentary rocks, of both deep- and shallow-water character, are present throughout Italy and well exposed in mountains and river valleys. Detailed studies of these sections by Italian geologists, beginning in the nineteenth century and continuing to this day, have produced a high-resolution biostratigraphy that allows identification of increments of geological time of less than a million years. Early work relied largely on ammonites to define biostratigraphy but was applicable primarily to sediments of Jurassic age. Study of deep-marine pelagic limestones and shales of Cretaceous age were subsequently, in the twentieth century, investigated using planktonic microfossils, the size of a sand grain, and even smaller nannofossils of micron scale. Pioneering work on magnetostratigraphy and cyclostratigraphy, undertaken primarily on Cretaceous sediments cropping out in Marche-Umbria, added further refinement to the measuring of small intervals of time in rock. With this stratigraphic background, distinct lithological and chemical signals, discovered first in Italian sequences, could be recognized world-wide and proven to be of global significance. In particular, the involvement of carbon isotopes has underscored the utility of chemostratigraphy, not only as a further aid to correlation, but also as a testimonial to major environmental change. Most significant in this context are the Cretaceous oceanic anoxic events, whose sedimentary record was first documented from Italy. These events were characterized by the development of organic-rich black shales deposited in waters largely lacking in oxygen during times of extraordinarily high temperatures known as hyperthermals. Hyperthermals, likely driven by supply of carbon dioxide from large-scale volcanic eruptions, illustrate the environmental impact on a planet affected by extreme global warming.

Published: June 2020

Walaupun banyak yang mengatakan pelajaran matematika itu sulit, namun tidak dapatdipungkiri bahwa matematika mempunyai banyak manfaat dalam kehidupan sehari-hari.Salah satunya adalah dalam menentukan wewaran dalam sistem tahun wuku di Bali.Perhitungan pada sistem tahun wukutidak mengacu pada peredaran benda-benda angkasa,tetapi tahunnya berdasarkan pada sistemnya sendiri, tanpa tergantung pada tahun suryaatau tahun candra. Satu tahun wuku lamanya 420 hari, terdiri dari 30 wuku (210 hari)dikalikan 2. Setiap wuku lamanya 7 hari, terhitung dari Redite, Coma, Anggara, Buda,Wrhaspati, Sukra, dan Saniscara. Sebulan dalam tahun wuku dibangun dari 5 wuku. Jadi 1bulan dalam tahun wuku lamanya 35 hari, diperoleh dari mengalikan 7 hari dengan 5 wuku.Satu peredaran wuku(30 wuku) termasuk 6 bulan dalam tahun wuku, 6 bulan ini diperolehdari mengalikan jumlah hari dalam sewuku dengan jumlah wuku (7 hari × 30 wuku = 210hari ). Dengan demikian 1 tahun wuku terdiri dari 2 kali peredaran wuku, yakni 7 hari ×30wuku× 2 = 420 hari. Keterkaitan wuku dan wewaran dalam sistem tahun wuku ditentukanoleh perhitungan matematis. Dalam perhitungan wewaran ini diperlukan nomor wuku dannilai/uripnya,terutamamenentukan rumus untuk mencari Tri Wara hingga SangaWara.Sedangkan nilai/urip Panca Wara dan Sapta Wara akan sangat berguna dalammenentukan Eka Wara, Dwi Wara, danDasa Wara.

Analyse sociopolitique de la fragilité de l’État du Cameroun
Authors: Mikonda Hermann , Mahini Bertrand-Michel
Published: June 2020

Certaines études considèrent la République du Cameroun comme faisant partie de la catégorie d’États fragiles. Le présent article se propose, à partir de ces travaux, d’ouvrir à nouveau le débat sur l’appartenance supposée ou réelle de cet État à ladite catégorie. Dès lors, l’analyse puise l’essentiel de sa démarche dans le portefeuille théorique du constructivisme social et de l’interactionnisme. Il est concrètement question de se demander s’il est vrai que le Cameroun présente les traits de caractère de la fragilité. Ce faisant, l’on montrera que les dynamiques développementalistes mises en œuvre par les pouvoirs publics et les partenaires internationaux le soustraient de cette situation négative pour l’orientation résolument sur le sentier du développement durable.
L’harmonisation de la loi pénale de forme au Cameroun
Authors: Mboumegne Dzesseu Serges Frédéric
Published: June 2020

La loi no 2005/007 du 27 juillet 2005 portant Code de Procédure Pénale a enrichi l’arsenal juridique camerounais. Cet enrichissement est perceptible à un double niveau: l’équilibre entre le procès pénal qu’elle organise et la protection des droits fondamentaux de l’homme impliqué dans la poursuite pénale d’une part et surtout l’abrogation du code d’instruction criminelle contraire à cet idéal et à l’ensemble des textes jusqu’alors appliqués dans la partie anglophone du Cameroun en matière de procédure pénale, d’autre part. Ce retrait des textes anciens consacre la conciliation entre plusieurs pratiques différentes liées au bi-juridisme camerounais sur le plan de la loi pénale de forme. L’intérêt de cette contribution, dont les analyses reposent sur la méthode juridique, porte sur les mécanismes adoptés pour faire face aux défis de l’harmonisation de la loi pénale de forme au Cameroun de même que l’intégration des aspects techniques novateurs tirés particulièrement du système anglo-saxon. Face à la coexistence des procédures, il fallait parvenir à l’harmonisation stricto sensu. En d’autres termes, il était question de rapprocher les règles de droit d’origine différente pour les rendre cohérentes entre elles en réduisant ou supprimant les différences et les contradictions pour satisfaire aux attentes communautaires.
L’intégration nationale à l’épreuve des replis identitaires au Cameroun
Authors: Jiotsa Albert
Published: June 2020

Sur la base des outils méthodologiques empruntés au champ de la sociohistoire, il est question, dans cette étude, de faire le point sur les avatars qui résultent du repli identitaire afin de contribuer à la réalisation intelligente du projet de construction de la conscience ou de l’identité nationale au Cameroun postcolonial. Pour y parvenir, il a été question de procéder à un recadrage historique des regroupements identitaires afin de dégager les éléments définitoires de l’identité nationale au Cameroun. Ce recadrage vise à souligner que la notion d’intégration nationale n’est nullement empreinte des représentations sociales liées au phénomène de repli identitaire. Bien plus, il s’agira d’analyser, dans une perspective historique, les conditions dans lesquelles l’on peut mouler l’identité nationale à partir de l’identité ethno-tribale. La double démarche structuro-analytique et sociocritique, combinée à l’étude synchronique des faits, permet de démontrer à suffisance que les éléments authentiques de l’âme camerounaise ne se perçoivent en l’identité ethno-tribale que dans le cadre de la prise en compte de la somme des valeurs identitaires positivistes.
Gouvernance identitaire et défis sécuritaires au Cameroun
Authors: Nguijoi Gabriel Cyrille
Published: June 2020

La montée en puissance des clivages identitaires est au centre des dynamiques et contradictions qui structurent la société camerounaise depuis plusieurs décennies, forgeant ainsi progressivement une rhétorique politico-sociale et sécuritaire plus ou moins consensuelle autour de l’insécurité. Ces clivages sont de plus en plus marqués par des fratricides à forte dominante ethnocentrée, voire ethnoconfessionnelle. La question sécuritaire s’impose donc comme une nouvelle priorité de l’action publique sur le changement immédiat du Cameroun d’une part et, d’autre part, comme mécanique de gestion politico-institutionnelle et « socio-stratégique » à l’aune du conflit lié à Boko-Haram et de la question anglophone. Les mouvements identitaires autour de ces deux spectres font désormais l’objet d’un regard attentif, bien que contrasté dans ses formes d’expression. Toutefois, ces mouvements participent curieusement d’une même impulsion réactionnaire quant à leur prise en charge prioritaire, de sorte qu’un ensemble de règles soit élaboré, mis en œuvre et contrôlé. Il en résulte alors une gouvernance des identités par le biais de la consolidation d’une conception communautariste, voire « communaucratique » du politique dans un contexte de brouillage historique et de nonchalance de l’idéologie nationaliste. Ce travail souligne la manière dont les réponses aux clivages identitaires ont été mobilisées. Pour ce faire, il a recours à la sociohistoire et à la sociologie critique, tout en mobilisant le constructivisme pour présenter subtilement la construction du modèle de gouvernance au Cameroun.
La sécurisation de la nationalité camerounaise à l’ère du numérique
Authors: Mbang Marcelle Lucette , Ada Christine Nadège , Nouazi Kemkeng Carole Valérie
Published: June 2020

Le droit à la protection des données personnelles est un droit récent lié au développement des TIC. Dans un contexte où l’état civil camerounais est devenu perméable à toutes sortes de manipulation, la politique gouvernementale s’inscrit résolument dans la logique de modernisation et de sécurisation de la nationalité. La présente contribution analyse les enjeux et les implications de la sécurisation de la nationalité camerounaise à l’ère du numérique. En prenant appui sur les méthodes juridique, systémique, sociologique et participative, il ressort de l’étude que le système d’identification sécuritaire s’impose comme une nécessité de modernité et de fiabilité des titres identitaires dans le but de consolider la nation camerounaise quoiqu’il se heurte à un certain nombre de défis.

Authors: Almeida Rui , Lobo Manuel
Published: June 2020

Apesar do papel predominante que os Técnicos de Radiologia desempenham no Serviço Nacional de Saúde, que tarda em ser devidamente reconhecido, e das diversas lutas que têm enfrentado na tentativa de obtenção de uma carreira mais digna e justa, seria inimaginável que viessem a travar uma luta totalmente diferente, contra um vírus desconhecido (COVID-19). Devido à sua extrema velocidade de propagação e incidência pandémica, houve a necessidade de adaptarem as práticas e serviços, de forma a minimizar o risco de infeção. Assim, o presente documento pretende identificar as evidências disponíveis na literatura relacionadas com o âmbito de atuação dos Técnicos de Radiologia e as estratégias adotadas de forma a minimizarem o risco de infeção. Através de uma revisão da literatura realizada nas bases de dados Scopus, ScienceDirect, Pubmed e Scielo, com recurso a diversos descritores de pesquisa, obteve-se um resultado final de 25 documentos, os quais foram analisados através de uma versão adaptada da Critical Appraisal Skills Programme. As evidências identificam diversos enfoques organizacionais nos departamentos de radiologia e nas práticas adotadas pelos Técnicos de Radiologia, com o objetivo de darem uma resposta adequada e segura no atual contexto pandémico. A consciencialização e o domínio dos procedimentos de proteção pelos Técnicos de Radiologia são referidos como prioritários, os quais devem ser obtidos através de treino e formação adequada. Os Técnicos de Radiologia estão, inevitavelmente, na linha da frente na luta contra a COVID-19 e têm desempenhando um papel insubstituível na prestação de cuidados de saúde.

A SARS-CoV-2/2019-nCoV (COVID-19), foi declarada pela Organização Mundial de Saúde como pandemia internacional, no dia 11 de março de 2020. Este trabalho tem como objetivo a partilha de procedimentos e boas práticas em TC, adotadas no contexto de um protocolo COVID-19 estabelecido no Serviço de Imagem Médica (SIM) do Centro Hospitalar e Universitário de Coimbra (CHUC) - polo Hospitais da Universidade de Coinbra (HUC), bem como a caracterização da amostra dos pacientes avaliados como suspeitos da COVID-19. Efetuou-se um estudo retrospetivo dos exames de TC realizados durante os meses de março e abril de 2020, para os quais foi accionado o protocolo. Após análise verificámos que 70% dos indivíduos realizaram exame entre as 18h e as 00h. No total da amostra, a percentagem de indivíduos do sexo masculino foi superior ao do sexo feminino, distribuindo-se os indivíduos pela faixa etária entre os cinquenta e oitenta anos de idade, em que o exame mais realizado foi a TC crânio encefálica. Sendo o Hospital Geral (HG) a estrutura assistencial dedicada ao SARS-CoV-2 / 2019-nCoV (COVID-19) e o polo HUC a estrutura de assistência à urgência geral, verificou-se uma redução global da sua atividade e consequente diminuição do número de exames realizados, relacionada com a fase epidemiológica. Apesar destas circunstâncias, verificámos que o número de exames de TC realizados aumentou com a procura dos serviços de urgência, não conseguindo estabelecer relação com a pandemia, uma vez que 90% dos exames realizados se relacionavam com doença não COVID-19. O envolvimento de toda a equipa dos Técnicos de Radiologia contribuiu para harmonização e otimização de procedimentos, minimizando riscos e garantindo a segurança de pacientes e profissionais.

Published: June 2020

Nearest neighbor analysis (NNA)-based procedures are proposed for the quantitative characterization of the spatial distribution of corrosion pits in metals. After the exposure of a carbon steel to a 3.5% NaCl solution mist, the results derived from observation of corrosion pit initiation and growth were used to justify the applicability of this approach. The pits initially comprised clusters that were superimposed on a randomly distributed background set. The clustered pits subsequently coalesced, evolving into a more random pit arrangement. Furthermore, it was revealed that in the early stages, the spatial pit distribution can be predicted via inspection of surface inclusions prior to the corrosion process.

Cyanobacterial blooms are recurrent phenomena in several water bodies, mostly eutrophic. They are considered a public health problem, especially considering harmful species like Raphidiopsis raciborskii, a bloom-forming cyanobacteria recorded as a producer of neurotoxic and cytotoxic alkaloids. The present study aimed to assess the acute toxicity of a saxitoxin-producing strain Raphidiopsis raciborskii ITEP-A1 on the zooplankter Macrothrix spinosa. Cladoceran clones isolated from an eutrophic system with cyanobacterial blooms records and an oligotrophic one with no bloom record; both from Pernambuco (Northeastern Brazil), were tested for R. raciborskii ITEP-A1 toxicity. Acute toxicity assays were carried out with newborns (<24h, n=10) and the animals were exposed to three concentrations of cyanobacterial cell biomass (Î¼gC L-1). Quantification of saxitoxins (STX and neoSTX) was done by high-performance liquid chromatography coupled with fluorescence detector (HPLC-RF). The EC50(48h) for the Duas Unas and Prata clones were 359 and 189 Î¼gC L-1, respectively. Obtained results showed that M. spinosa Prata was more sensitive to R. raciborskii than Duas Unas, reinforcing the importance of analyzing the previous life history of the test organisms regarding their native environments. However, both clones demonstrated high sensitivity to R. raciborskii, which enhances their potential for biomonitoring toxic cyanobacterial blooms in tropical reservoirs.

Chlorpyrifos is an organophosphate insecticide widely used and it acts as an inhibitor of cholinesterases, overstimulating the nerve endings. This study analyzed the genotoxic effect of the organophosphate insecticide Chlorpyrifos upon the induction of micronucleated erythrocytes in the blood of Odontophrynus carvalhoi Brazilian neotropical tadpoles submitted to four different nominal concentrations of this insecticide (10, 100, 200 e 400 mg L-1) during 96 hours. The tadpoles were anesthetized, euthanized and their blood was collected through cardiac puncture and later on cyto smears were performed and stained with May Grunwald Giemsa. The frequencies of micronucleated erythrocytes were determined at different periods of exposure (24h, 48h e 96h) through the analysis of 1000 erythrocytes for each tadpole. The tadpoles that were submitted to the Chlorpyrifos showed high frequencies of genetic changes (micronuclei) when compared with the negative control. The differences in the frequencies of the micronuclei registered after 48 hours of exposure were statistically significant (p<0.05). Thus, it can be concluded that tadpoles of O. carvalhoi were susceptible to genetic alterations induced by the use of the commercial formulation of chlorpyrifos (Klorpan®), showing a clastogenic effect in the erythrocytes of this species. The use of this species as an animal model for genotoxic studies has shown promise.

With the widespread use of the Internet, there are more and more opportunities to purchase a variety of products through online shopping. The opportunities are not only for small products such as books, but also for home appliances. Previously, when purchasing a product, users who wanted to buy a product would visit a store and get expert advice on what to buy. Now, however, customers consider reviews on the Internet to be more important information for considering the products to be purchased. And evaluation page consists of an overall evaluation, an evaluation of each feature, and comments, which are word of mouth. The overall evaluation and the evaluation of each feature is often a score evaluation, and organized information such as the average and the distribution of scores are presented. However, it is difficult to read all the comments that are word of mouth because they are often enumerated as is. Therefore, in this study, we created a system to label which features people commented on in response to the word of mouth comments using data from the TV’s comprehensive evaluation page. 2392 TV evaluation results from Sony.com were used. From the extracted data, text mining was performed on the comments, which are word of mouth, followed by labels of which features are commented on. When 80\% of the test data was prepared and implemented against 20\% of the learning data, the label was predicted with 77\% accuracy. From this study, we used text mining to label the comments, which are customer impression. from the current study, text mining was used to label the comments, which are customer impression. The results and score ratings were used to identify customer trends.

Project-Based Learning is an approach that is significantly different from the conventional English Language Teaching method. PBL has been advocated as an effective instruction that promotes the simultaneous acquisition of language, content, and 21st-century skills to EFL (English as a foreign language) and ESL context. In this study researcher’s attempt is to integrate PBL (Project-Based Learning) approach, which incorporates authentic, learning by doing, problem-solving, critical thinking and team working skills with ESP (English for specific purposes) courses. The study aimed to investigate whether the PBL projects assist EFL learners in acquiring department related literature and information in the English language and the effect of project work on learners’ ESP course academic achievement. The study was conducted at Tishk International University, formerly known as Ishik University, in Iraq-Kurdistan Region with 2 Engineering (Architectural and Civil engineering) and Business and Management departments’ students. A mixed-method approach was designed to make the authentic interpretation of gained results. Quantitative and Qualitative instruments were utilized to probe the effect of PBL in the ESP course of undergraduate Iraqi EFL learners. The findings of this study reveal that PBL had a significant positive effect on acquiring department-related vocabulary and information in English as well as learners’ ESP course academic achievement showed statistically significant increment.

De beperkingen van (en bij) functionele invaliditeit

In de beoordeling van letselschade wordt de medisch adviseur geregeld gevraagd een uitspraak te doen over de blijvende invaliditeit en blijvende beperkingen van het opgelopen letsel, al dan niet na inschakeling van een onafhankelijke expertise. Daarin doen zich discrepanties voor. De mate van de functionele invaliditeit staat los van de mogelijkheid tot het verrichten van arbeid en het ervaren van kwaliteit van leven.
