Barrier islands as coupled human–landscape systems
Authors: McNamara Dylan , Lazarus Eli
Published: April 2021

There are nearly 300 barrier islands between Maine and Texas, and of these, at least 70 are intensively developed. Mean population density along the U.S. Atlantic and Gulf coasts are the highest in the country. Such concentrated development exists and continues despite the fact that barrier islands are transient landscapes, not only over geologic time scales of millennia but also within human and economic time scales of centuries to decades. Populated barrier islands are inherently vulnerable to natural hazards such as sea-level rise, cumulative erosion, and storm events; this vulnerability drives humans to actively modify barrier geometry and environments. The most common manipulations are beach nourishment, to mitigate shoreline erosion, and increases to dune height or seawall construction to prevent flooding and damage from overwash during storm events. Over time scales of years to decades, hazard-mitigation actions impact natural, spatio-temporal barrier processes such as washover deposition and planform transgression, which in turn affect future efforts to manage, control, or prevent barrier change. Through their maintenance and persistence, interventions against coastal hazards represent a significant dynamical component of developed barrier-island system evolution, such that, within the past century, human actions and natural barrier-island processes have become dynamically coupled. This coupling leads to steady-state barrier island behaviors that are fundamentally new. The only way to understand how developed barrier islands will respond to climate change over decadal time scales is to treat these settings as strongly coupled human–natural systems. Over time scales longer than centuries, human interventions may be coupled only weakly to long-term barrier dynamics. Short of major technological advancements or sweeping decisions to transform these environments into comprehensively geoengineered terrains, high-density development on U.S. barrier islands will likely cease to exist in its current configuration.
Zwischen Protest und Parodie: Strukturen der »Querdenken«-Kommunikation auf Telegram (und anderswo)
Authors: Holzer Boris
Published: April 2021

The paper investigates the structure of digital communication among corona-sceptic groups on Telegram. Starting from the local group "Querdenken 753," it analyzes a communicative network that connects the anti-lockdown protests with a large number of Telegram accounts, ranging from news sources over conspirational to extremist channels. Criticizing the "mainstream" media, science and politics, the arguments and framing strategies in this network imitate but also parody how information, facts and truth are negotiated in public discourse.
Informing Citizen Engagement Activities about Human Genomics in Europe
Authors: Rojas Clarissa Jazmin Rios , Pereira Jose Carlos , Rosa Paulo
Published: April 2021

This article aims at informing forthcoming citizen engagement initiatives about human genomics and gene editing in particular in Europe. In order to initiate such a debate, it is necessary to uncover what has been guiding public discourse and in particular public debate about human genomics and gene editing. Moreover, it is also necessary to understand the grounds upon which human genomics is being currently governed. The authors present an assessment of citizen engagement on debates about human genomics, identifying common problematics found in different studies. The lack of citizen engagement activities about human genomics thus far suggest that there is a need to create opportunities for debate about this technology and its potential applications. This will constitute a necessary next step on the research about social and ethical implications of human genomics. In light of this, the authors set forth seven thematic narratives enshrined in policy and media discourses, as well as human genomics practices. These narratives come from different actors and are telling about on-going promises, assumptions, claims, interests, expectations and concerns across the human genomics field. The narratives can function, firstly, as a means to introduce or trigger the conversation in the desired topics through the exploration of the plausibility and desirability of such narratives from the point of view of the relevant actors, and secondly, to gather insights of the imaginaries and expectations of citizens related to the discourses on human gene editing.
Deindustrialization and the Postsocialist Mortality Crisis
Authors: Scheiring Gábor , Azarova Aytalina , Irdam Darja , Doniec Katarzyna Julia , Mckee Martin , Stuckler David , King Lawrence
Published: April 2021

An unprecedented mortality crisis struck Eastern Europe during the transition from socialism to capitalism. Working-class men without a college degree suffered the most. Some argue that economic dislocation caused stress and despair, leading to adverse health behavior and ill health (dislocation-despair approach). Others suggest that hazardous drinking inherited as part of a dysfunctional working-class culture and populist alcohol policy were the key determinants (supply-culture approach). We enter this debate by performing the first quantitative analysis of the association between economic dislocation in the form of industrial employment decline and mortality in postsocialist Eastern Europe. We rely on a novel multilevel dataset, fitting survival and panel models covering 52 towns and 42,800 people in 1989-1995 in Hungary and 514 medium-sized towns in the European part of Russia. The results show that deindustrialization was significantly associated with male mortality in both countries directly and indirectly mediated by adverse health behavior as a dysfunctional coping strategy. Both countries experienced severe deindustrialization, but social and economic policies seem to have offset Hungary’s more immense industrial employment loss. The policy implication is that social and economic policies addressing the underlying causes of stress and despair can improve health.

Published: April 2021

Abstract:

Background: Sarcoidosis is a chronic inflammatory disorder characterized by non-caseation granuloma. It is an inflammatory disorder of unknown etiology. Sarcoidosis has variable ocular presentations   from anterior uveitis to rare venous occlusions.

Case: We present a rare case of sarcoidosis with bilateral hilar lymphadenopathy and a compatible uveitis. Positive findings of mutton fat keratic precipitates, Koeppes nodule, posterior synechiae, trabecular meshwork nodules, Candle wax dripping sign, Branch retinal vein occlusion and choroidal granuloma in one eye supported the diagnosis of sarcoidosis. Elevated serum acetylcholine esterase and bilateral hilar lymphadenopathy also confirmed the diagnosis of sarcoidosis.

Observation: The patient responded well to oral steroids and laser photocoagulation of the vein occlusion area. The patient developed complications of steroid like Herpes Zooster of abdomen and avascular necrosis of femur.

Conclusion: Branch Retinal Vein Occlusion is a rare vascular complication in ocular sarcoidosis. Systemic steroids and laser for vein occlusion is mainstay of treatment. Physician must be aware of serious complications of steroid therapy, as seen in this case.

Authors: Thapa Bikram Bahadur , Singh Sweta , Lamichhane Gyanendra , Gurung Shanti , Piya Saurav
Published: April 2021

Introduction: Posterior segment retained Intraocular foreign body (IOFB) management is challenging. Facility of pars plana vitrectomy (PPV) and availability of well trained vitreo retina surgeons are the basic need to accomplish this work.  Encircling band provide permanent 360° support to close the anterior retinal break and prevent traction on the retina. The objective of this study is to analyse the clinical characteristics and predictors of the final visual outcome and survival of the globe in cases of retained IOFB in the posterior eye segment.

Materials and methods: A hospital based retrospective observational study was conducted. All the patients of retained IOFB in the posterior segment presented from January 2016 to June 2019 were enrolled. Patients presented with visual acuity of NPL were excluded. Statistical analysis was performed using a variety of tests using SPSS version 21.  

Results: Forty eyes of 40 patients were included. The mean age was 27.08±10.68 years (range 5-66). 95% of our patients were male. Most of them (52.5%) worked on the farm. 26(65%) of 40 eyes had Zone I injury. The median time spent before presentation was 13.5 day. Retinal detachment, vitreous hemorrhage, and endophthalmitis were present in 15, 23 and 5 eyes, respectively, before IOFB removal. The mean LogMAR visual acuity was improved significantly from 2.50±0.87 to 1.33± 1.01 (p=0.003). Poor presenting visual acuity, retinal detachment and large diameter of IOFB were found as the predictor of poor final visual acuity.

Conclusion:  Pars plana vitrectomy by a vitreo retinal surgeon can give encouraging results in the cases of retained posterior segment IOFB. Poor presenting visual acuity, large diameter of IOFB and RD before IOFB removal are predictors of poor visual outcome.

Authors: Bhattarai Binita , Shrestha Koshal , Manandhar Laxmi Devi
Published: April 2021

Introduction: Non Endoscopic endo-nasal dacryocystorhinostomy retains the benefit of an Endo-nasal approach and can be done without using an expensive video endoscope or laser system.

Case presentation: A 22 years old female presented with epiphora and medial canthal mass in her left eye, accompanied by discharge and recurrent conjunctival congestion since childhood. Physical examination revealed loss of height of the nose with discharge in her left eye, and am immobile and non-tender mass below the level of medial canthal tendon. On applying pressure over the lesion there was mucopurulent discharge from both the upper and lower punctum . The bridge of the nose was very flat and external dacryocystectomy was a challenge. A non-endoscopic endonasal dacryocystorhinostomy with silicon tube intubation was planned. During the procedure, the bone was lower than normal requiring more bone nibbling. Epiphora was resolved immediately after surgery.

Conclusion: Non-Endoscopic endo-nasal dacryocystorhinostomy has the benefit of doing it through an endo-nasal approach without expensive and space consuming video-endoscope making more room for bone nibbling even in a narrow and deformed nasal cavity.
Bhishma as a Superman in the Mahabharata
Authors: Bhandari Sabindra Raj
Published: April 2021

This article explores and interprets Bhishma, one of the great heroes in the classical epic the Mahabharata, from the perspective of superman that the great philosopher Nietzsche postulates in his great work Thus Spoke Zarathustra. The superman is one of the alluring concepts in the domain of entire philosophy. He has his own ideals, standards, and thus becomes the creator of his own self. Sacrificing himself for the morals and dignity, he becomes an emblem for the righteousness, truth, and virtues. He stands for the sake of justice and righteousness, and suffers to rise himself even beyond the dualities of the world. Nietzsche’s superman is a man transcendent. Bhishma, in the great epic the Mahabharata, also establishes his own values. He suffers a lot, but does not surrender. As a superman, the more difficulties he faces, the more he fills himself with new vibrations and vitalism in his life. His great pledge and his self sacrifice for the truth really transform him into a superman. Therefore, the creative evolution of Bhishma mirrors the genuine ideals of the superman. This paper applies the qualitative approach, and attempts to add a new dimension while interpreting and exploring the ideations of superman in one of the great heroes from the longest epic the Mahabharata.
Diaspora and Diasporic Literature: Condition to Consciousness
Authors: Pokharel Bhawana
Published: April 2021

The term "Diaspora" originated from the experience and state of the Jews of being exiled into many countries back in the eighth century BCE. However, the definition of diaspora derived from the Jewish condition has changed and expanded; so has the concept of diasporic literature. In this context, the aim of this article is to inform the readers that there are some clear lines of demarcation between these key terms namely “Diaspora” and “Diasporic Literature” by showing the discrepancy between these two key terms that are most frequently used and are liable to be conflated in existing and upcoming diaspora discourse due to lack of its deeper understanding. This paper draws from the scholars like Martin Bauman, Robin Cohen, Thomas Faist and Uma Parmeswaran who write on diaspora, and brings it into open discussion among academics whether being a diaspora is a condition or a consciousness? The article discusses how has diasporic literature so far been understood and what are the alternative ways to comprehend it. It concludes that if a piece of literature has some of the qualities of diasporic literature as articulated by Parmeswaran, it will be apt to call it diasporic literature, instead of labeling it as emigrant’s or immigrant’s literature based on the origin, e/(im)migration, station or mobility of the author.

This article explores World War I Hero, Expatriates: Money and Body are two major objects for males’ pleasure. The very title is slightly discussed applying psychoanalytical approach. Mainly, it studies focusing on Freudian and Jungian concepts of Sex and Sexuality. Statement of problems is to find out what made the people go outside the country as expatriates mainly to the protagonist Lieutenant Frederic Henry and Catherine Barkley, in the novel A Farewell to Arms, written by Ernest Hemingway. Furthermore, this article tries to analyze World War I Hero and Expatriates: Money and Body for Male’s pleasure with reference to some critics in the body part of this article. In A Farewell to Arms, the hero, Frederic Henry, is badly injured by the bomb shell in the Italian front during the World War I. He is admitted to the Milan hospital and has been involved with the nurse Catherine Barkley. She is a volunteer nurse and the central character. However, the hero, Henry is attracted towards her for his pleasure not only from the perspective of money but for body and pleasure. These two characters represent the American and British expatriates who are crowding the bars, restaurants, night clubs, bull fight sports or in different entertaining places getting fed up with the horrors of World War I. They live comfortably in the foreign country. They want to get rid of the war and weapons so that they can enjoy as outsiders in the foreign countries as expatriates.

Herbs are the fresh or mixtures of dried leaves, seeds, grasses, nuts, barks, fruits, flowers, or other botanical elements. The production and uses of herbs are not new to the Worlds and Ethiopia. However, there is no such compiled information about herbal tea and its uses in Ethiopia. Herbs have a long history of both culinary use and health benefits, as well as acting as preservatives. Many herb plants are widely used as cooking to enhancing the flavor of foods including meats, sauces, vegetables, and health benefits by ensuring protection against harmful free radicals which consequently damaging of cellular structures, which contributes to the development of many diseases, have analgesic, anti-inflammatory, anti-bacterial, anti-viral and antiallergic. Drinking herbal teas has the advantage of boosting energy levels and invigorating the body, quenching the body by preventing hydration of the body, it promotes night sleep due to caffeine-free and it also has distinctive sensory qualities due to it contain the volatile fractions of various aroma active compounds. Herbal tea can be prepared by infusion or decoction using water on the whole or reduced to a suitable size and allowing too steep for a defined period. This review gives information on the production and the uses of herbal in the form of teas.

Published: April 2021

Objective: To correlate non-restricted diffusion magnetic resonance imaging (MRI) patterns of hepatocellular carcinoma (HCC), with histopathology and clinical outcome.Material and Methods: We retrospectively evaluated pre-treatment MRIs showing non-restricted diffusion HCC lesions (≥1-centimeter), excluding lesions with poor quality/non-available diffusion weighted imaging (DWI). Three radiologists evaluated 37 lesions in 27 patients, for: T1-weighted (T1W)/T2-weighted (T2W) characteristics, arterial enhancement, washout on portal venous/delayed phase, capsular enhancement, intralesional fat component and presence of cirrhosis. Histopathological reports were categorized as: well/moderate/poorly differentiated. Kaplan-Meier survival analysis was calculated for clinical outcome.Results: From a total of 37 lesions, 24 lesions had available pathological grading, which revealed well and moderately differentiated equally (12 lesions each). None of the non-restricted diffusion HCCs were poorly differentiated. Thirty-five of the 37 lesions (94.6%) showed arterial enhancement with washout; 34 lesions (91.9%) were T2W hypo-/isointense, 33 esions (89.2%) were T1W iso-/hyperintense, 19 lesions (51.4%) showed capsular enhancement and 8 lesions (21.6%) had intralesional fat. These findings in the well and moderately differentiated groups were not significantly different (p-value 0.178-1.000). Overall mean-survival was 6.972 years (95% confidence interval (CI); 5.3-8.6). The 1-year, overall survival rate was 83.6% and for 3-years was 67.9%. Mean survival of well and moderately differentiated groups were 6.88 and 7.23 years (95% CI 5.7-8.0 and 4.4-10.1), respectively (p-value=0.319).Conclusion: DWI may help to predict histological grading of HCC and clinical outcome. We found that non-restricted diffusion HCCs were histologically well or moderately differentiated, with no significant difference of imaging findings and survival rates between the two groups. No poorly differentiated lesions were seen in our non-restricted HCC cohort.
The Effects of The Tanzanian Railway Network in the Performance of the Rail Freight Operations

Published: April 2021

The railway is the fundamental means of transport, especially for freight. It has a substantial contribution to the sustainable economy of the country and the region at large. However, some factors have been affecting the performance of rail operations; especially for freight, to the extent of reducing the modal share from rail to roads. This has been resulting in high road maintenance costs and underutilization of the available capacity in the railway. This research has studied the factors affecting the Tanzanian railway network in the performance of rail freight operations. The focus was on the corridor from Dar es Salaam to Isaka because it serves most of the landlocked countries such as Uganda, Burundi, Rwanda, and Eastern DRC. The study used the Performance Measurement theory with the Balanced Scorecard model. Data analysis was done by the Linear Regression statistical method with the aid of SPSS version 20. The results of the study show that derailments, washouts, and rail freight wagons maintenance capacity directly affect the performance of rail freight operations. TRC, therefore, needs to strategize measures for ensuring that derailments and washouts are very much reduced. A plan for quick recovery must be in place in case a derailment or washout happens. Also, TRC should enhance its capacity for maintaining the rail freight wagons to ensure its optimal availability. Railway should be viewed as a potential area for investment because it supports the growth of other sectors as well. If constraints are minimized in the railway system; the performance of rail freight operation will be high and many customers will be attracted to use the railway as a preferred mode of transport, hence, the modal share to the railway will increase.

Published: April 2021

In the field of geotechnical – soft soil improvement, the mathematical model or mechanical model is one of the important input parameters for the design calculations or studies. The determination of the appropriateness of the models has a great influence on the accuracy results of design and calculation as well as the sustainable stability of soft ground after improvement. On the contrary, the selection of inadequate calculation models will lead to increased costs of soft soil improvement, possibly even leading to the destabilization of the work and causing immense loss of people and property. Recently, many projects major highway after construction design in use has not meet the requirements of the standard, leading to wasted money and time of individuals, organizations, and the state of post-treatment. Therefore, the research and application of using mathematical or mechanical models in accordance with the new soft soil improvement method will greatly help as well as add additional options for soft soil improvement in Vietnam. The soft soil deformation is not only related to load but also to load time. The change in stress and deformation of weak soil over time is called rheology, and in this study is the viscoelastic behavior. From the above reasons, we try to apply a generalized Maxwell model to explain the viscoelastic behavior of a soft soil. In particular, the time-dependent behavior of a viscoelastic soft soil was represented by using the Maxwell rheological model. The Matlab programming code helps to solve numerically all the equation of the mathematical exhibition of the generalized Maxwell model results. We acknowledge that the generalized Maxwell model is superior in demonstrating the time-dependent behavior of soft soil. The results probably show that this is one of the effective models to predict the behavior of soft soils in ground improvement with GEC.

Regeneration of Medicinal Plant Paederia foetida through Direct Organogenesis using Nodal Explants
Authors: Binto SH , Ahmed JU , Ghosh TK
Published: April 2021

Chinese fever vine (Paederia foetida L.), a valuable medicinal plant has been greatly utilized in therapeutic purposes throughout the world. Since conventional propagation techniques of P. foetida are very slow, inefficient and cannot cope with the increasing demand, in-vitro regeneration through tissue culture could be an alternative means of rapid propagation. Therefore, the efforts were made to develop a suitable protocol through direct organogenesis of P. foetida. After surface sterilization, the nodal explants were cultured in Murashigue and Skoog (MS) medium and MS medium supplemented with different concentrations and combinations of plant growth regulators. MS medium supplemented with 6-benzylaminopurine; BAP (2.0 mg L-1) produced the maximum number of shoots; 4.40 ± 0.98 and 5.40±1.12 after 15 and 30 days of culture respectively. The number of shoots gained by 15 days was found to be the highest; 1.20±0.80 at BAP (4.0 mg L-1) followed by 1.00±0.55 at BAP (2.0 mg L-1). Although the combination of BAP + Kinetin (2 mg L-1 +2 mg L-1) showed the highest shoot growth (3.40 ± 1.08 cm) by 15 days, sole application of BAP (2.0 mg L-1) or Kn (0.5, 1.0, 2.0 and 3.0 mg L-1) showed similar responses. BAP (2.0 mg L-1) showed the best responses for developing the highest number of leaves; 18.60 ± 2.42 and 29.20 ± 2.73 respectively after 15 and 30 days of culture. Similarly, development of the maximum number of leaves (10.60 ± 0.68) was reported by 15 days at BAP (2.0 mg L-1). Rooting was significantly induced in indole-3-acetic acid (IAA) supplemented to 1/2 strength MS medium as compared to control (only ½ strength MS medium). The best performance of rooting was observed by 0.5 mg L-1 IAA which produced average 4.33 roots per shoot after 21 days of culture. The regenerated plants showed similar morphology to the mother plants. Thus, a suitable protocol for successful multiplication of P. foetida in vitro was established using nodal explants.

As associações micorrízicas são estratégias utilizadas pela maioria das plantas vasculares, com o intuito de aumentar a área de absorção de água e nutrientes. No entanto, o estabelecimento dessa associação é modelado pelos fatores ambientais, entre elas a precipitação pluviométrica. O objetivo desse estudo foi avaliar a relação entre precipitação pluviométrica e a colonização microrrízica em plantas de pau-rosa e mogno. Foram realizadas coletas de raízes e solos rizosféricos nos meses de agosto/2005, dezembro/2005 e março/2006. As variáveis analisadas foram o percentual de colonização micorrízica (%), a intensidade de colonização (%) e a densidade de esporos no solo sob o plantio. De maneira geral, a colonização micorrízica foi maior no sistema radicular do pau-rosa. Os esporos micorrízicos apresentaram variação sazonal marcante, com maior densidade registrada na rizosfera do pau-rosa no mês de março, e mogno no mês de dezembro. A colonização média das raízes por FMA foi influenciada pela disponibilidade hídrica, com maior taxa de colonização e de esporos no período de maior quantidade de chuvas. O mogno apresentou maiores concentrações de Ca, Mg e, menores concentrações de Mn nas folhas do que o pau-rosa. Ambas as espécies mostraram as mesmas sequências de concentração de macronutrientes nas folhas: Ca>K>Mg>P. A sequência de concentração de micronutrientes nas folhas no pau-rosa foi Fe>Mn>Zn e no mogno foi Fe>Zn>Mn. Houve correlação significativa positiva das colonizações radiculares por fungos micorrízico-arbusculares e teores de Ca e Mg nas folhas do pau-rosa no mês de dezembro e, negativa para os teores de Zn nas folhas do mogno nos meses de março e dezembro.

O sul da Bahia apresenta importantes remanescentes do bioma da Mata Atlântica. Existem duas formas de preservá-las, através das unidades de conservação e também pelo sistema de produção de cacau (Theobroma cacao). Este último funciona sob as árvores nativas do bioma e enfrentou uma grave crise, que começou em meados da década de 1980 pela tendência negativa dos preços de cacau bulk no mercado internacional e foi agravada pela praga vassoura-de-bruxa (Moniliophtora perniciosa), de consideráveis impactos negativos seja na produtividade da lavoura de cacau e/ou pelo uso dos recursos naturais. Foram realizadas pesquisas no intuito de identificar soluções, como é o caso da introdução de clones de cacau mais tolerantes à Moniliophtora perniciosa. Entretanto, a introdução do Sistema AgroFlorestal (SAF) no MAPES (Mosaico de Áreas Protegidas do Extremo Sul da Bahia) apresentou o potencial de incentivar nos agricultores a produção de cacau, pois segundo a modelagem econômica, proposta por este artigo, foi demonstrada viabilidade econômica na projeção temporal de vinte anos. Além dos retornos financeiros, que superaram as taxas de custos do Sistema Agroflorestal composto pelo cacau (espécie exótica) e outros 52 indivíduos de espécies nativas, tem-se a possibilidade de incrementar a vegetação nativa do bioma da Mata Atlântica.

Objetivou-se neste estudo realizar a fitoquímica das folhas de Tapirira obtusa e testar seu potencial alelopático na germinação e formação de plântulas de três espécies-alvo. Extratos foram utilizados nas concentrações de 25, 50, 100, 150 e 200 mg mL-1 para sementes de alface e tomate e, 100 e 200 mg mL-1 para fedegoso, em câmara de germinação, sendo avaliadas a porcentagem, índice de velocidade, tempo médio de germinação e formação de plântulas. Em casa de vegetação, utilizou-se o pó das folhas em proporções de 5, 10 e 20%, avaliando-se o crescimento. O delineamento experimental foi inteiramente casualizado, aplicando-se a análise de variância. A análise fitoquímica revelou alta intensidade de compostos fenólicos e triterpenos e média intensidade de flavonoides e taninos. Os extratos interferiram na germinação e crescimento em câmara de germinação e casa de vegetação, com o forte efeito alelopático, indicando o potencial de uso da espécie no controle de espécies indesejadas.

Os derivados da Cannabis sativa estão sendo utilizados para tratar comorbidades que ainda não apresentam terapêutica eficiente sobre os danos e sintomas. Os compostos canabinoides – canabidiol e delta-9-tetrahidrocanabinol vem sendo testados para uso terapêutico e diversos estudos buscam elucidar os efeitos farmacológicos dessas substâncias. Assim, o presente estudo reúne informações sobre os derivados canabinoides e os efeitos farmacológicos já descritos para os compostos canabidiol e delta-9-tetrahidrocanabinol. Foi realizada uma revisão integrativa da literatura a partir de dados colhidos de artigos originais obtidos nas bases de dados: MEDLINE, SciELO, BVS e LILACS, utilizando os termos: canabinoides, canabidiol, tetrahidrocanabinol (dronabinol), maconha medicinal. O conhecimento sobre os ligantes endocanabinoides demonstram que os compostos canabinoides podem apresentar função significativa na mediação de diversos processos neurofisiológicos. Pesquisas evidenciam que esses derivados são uma importante alternativa para o tratamento de várias patologias, principalmente sobre doenças que ainda não possuem resposta ou que a resposta não seja tão eficaz. Dados reforçam que os canabinoides podem ser uma opção terapêutica para pacientes em quimioterapia auxiliando nas crises decorrentes do tratamento, além de auxiliar no tratamento de trauma raquimedular, AIDS, esclerose múltipla, neuropatia periférica, síndrome de Tourette, no pós-operatório, em fase pós-infarto cerebral ou outras condições clínicas que tenha uma forte associação com quadros de dores crônicas. Ainda que os avanços científicos demonstrem benefícios no uso dos compostos canabinoides ainda carece de estudos para comprovação da ação. Pesquisas com Cannabis sativa abrem espaço para a possibilidade de tratamento de doenças que ainda não possuem resposta terapêutica tornando estas substâncias uma esperança farmacêutica.

A literatura disponibiliza uma diversidade de ferramentas metodológicas para análise de dados coletados em uma pesquisa qualitativa com viés educacional. Dentre as propostas existentes encontramos o método denominado tematização ou análise temática, que tem como objetivo organizar os dados coletados da pesquisa de forma que possibilitem o melhor tratamento dos achados encontrados na pesquisa, cabe salientar que esses dados são coletados por meio de entrevistas, materiais escritos e depoimentos orais. Deste modo, a tematização é uma ferramenta que pode auxiliar a sistematização do material coletado e possibilitar ao leitor uma leitura rica e articulada. Diante disto, este artigo tem como objetivo apresentar um estudo de caso, no qual foi empregada a análise temática nos dados coletados durante a ministração de um curso de formação para professores de ciências dos anos finais do ensino fundamental, nas cidades de Três Rios e Paraíba do Sul (municípios do interior do Estado do Rio de Janeiro), cujo o tema foi “Oficina de atividades lúdicas para o ensino de Microbiologia no Ensino Fundamental”. Nessa perspectiva, o trabalho mostrou que diante da complexidade de informações coletadas durante o curso de formação a tematização foi um instrumento que possibilitou uma maior reflexão e uma articulação com a teoria.

A efetivação dos princípios do Sistema Único de Saúde é um grande desafio para a Atenção Primária de Saúde, porque depende da presença dos atributos de saúde. O acesso refere-se à utilização dos serviços de saúde pelo usuário, e quando ausente pode acarretar no baixo desempenho do Sistema e supostamente aumentar a taxa de Internações por Condições Sensíveis à Atenção Primária. Objetivo: Avaliar as condições do acesso ao serviço prestado pela Atenção Primária de Saúde na Região de Saúde Sudoeste I. Materiais e Métodos: Estudo transversal com abordagem quantitativa, realizado por meio de dados secundários referentes às Internações por Condições Sensíveis à Atenção Primária extraídos do Sistema de Informações Hospitalares e aplicação do instrumento PCATool – Brasil para pacientes internados em leitos públicos. Utilizado o Microsoft Excel para refinamento dos dados e um programa estatístico para análise descritiva. Resultados: Ocorreram 19.993 Internações por Condições Sensíveis no município de Rio Verde no período de 2010 a 2019. Prevaleceram os diagnósticos de insuficiência cardíaca, pneumonias bacterianas, gastroenterites infecciosas e complicações, infecção no rim e trato urinário e doenças pulmonares. Dos 260 entrevistados entre abril/2019 e março/2020, 51,92% referem-se a adultos e 48,07% a crianças; 77% não possuíam nenhum grau de afiliação à APS. Conclusão: O acesso ao serviço prestado pela APS da região estudada se encontra insatisfatório, sendo necessário a reformulação das políticas públicas, programas e ações de saúde que estão sendo desenvolvidos a fim de aumentar a cobertura na região.
Perdas produtivas e financeiras geradas por vibrações e impactos em esteiras transportadoras em aviários: revisão bibliográfica
Authors: Mollo Neto Mario

O Brasil é um grande produtor de ovos e o Estado de São Paulo é que mais produz ovos do Brasil, sendo a região de Tupã a maior produtora no Estado com 55% da produção e, em 2018 Bastos, a cidade com maior produção, aportou 36% do total paulista. Assim, com estes volumes de produção, é possível compreender a importância deste setor produtivo, que demanda inovações tecnológicas para garantir a permanência no mercado e a eficiência na produção. A implantação de novas tecnologias para automatização da produção de ovos, nem sempre trazem só resultados positivos, mas demandam ajustes para que se evitem perdas durante o processo produtivo. Neste contexto, destaca-se o problema advindo dos sistemas automatizados de transporte dos ovos, que podem causar perdas produtivas e financeiras para as granjas. Há perdas na linha de produção durante o transporte automatizado desde os galpões até o processo final de expedição, onde vibrações e impactos causam danos, assim como os tempos de exposição ao sol. Considerando o cenário descrito, neste artigo o gol baseia-se na prospecção da bibliografia que demonstrou que já há tecnologia desenvolvida pelos pares para dar suporte integral ao futuro desenvolvimento tecnológico de um sistema eletrônico autônomo para ser lançado ao sistema de transporte, coletando dados dos obstáculos, sua posição e condições de exposição às intempéries, passível de comunicação com computadores do sistema de gestão dos aviários e que possam dar informações de forma a mitigar as perdas produtivas, ampliando a competitividade e segurança alimentar das granjas.
