Authors: Salvador Verges Àngels , Fernández-Luque Luis , Yildirim Meltem , Salvador-Mata Bertran , Garcia Cuyàs Francesc
Published: September 2018

BACKGROUND

Over the past 60 years, no technique used for treating cartilage disorders has been completely successful. Bioprinting provides a highly anticipated, novel alternative solution to this problem. However, identifying barriers to this new technology is crucial in order to overcome them when bioprinting reaches the implementation stage. This kind of research has been declared essential because clinical efficacy and safety studies alone do not always lead to successful implementation.

OBJECTIVE

This qualitative study aimed to explore the stance of orthopedic surgeons on the use of bioprinted cartilage grafts for cartilaginous lesions. The study sought to summarize and classify the barriers and facilitators of this technique and to identify the key factors for successful implementation of bioprinted cartilage in routine clinical practice.

METHODS

A qualitative thematic analysis method was used to evaluate data obtained from semistructured interviews and from focus groups. Data were collected between June 2017 and February 2018. Interviews focused on the collection of expert opinions on bioprinted cartilage.

RESULTS

The perceived barriers to the adoption of this technology were (1) awareness of a lack of information on the status and possibilities of this technology, (2) uncertainty regarding compliance with current health care regulations and policies, and (3) demands for clinical evidence. The facilitators were (1) lack of surgical alternatives, (2) the perception that research is the basis of the current health system, and (3) the hope of offering a better quality of life to patients.

CONCLUSIONS

The results of this study are preliminary in nature and cannot be generalized without a broader group of participants. However, the key factors identified provide a frame of reference to help understand the challenges of bioprinted cartilage and help facilitate the transition toward its clinical use. These findings will also provide information for use at multidisciplinary meetings in scientific societies; create bridges between researchers, orthopedic surgeons, and regulators; and open a debate on the funding of this technique and the business model that needs to be developed.

The reliability (unreliability) and life testing are important topics in the field of engineering, electronic, medicine, economic and many more, where we are interested in, life of components, human organs, subsystem and system. Statistically, a probability distribution failure time (life time) of a certain form is usually assumed to give reliability of a component for a system for each time t. Some well known parametric life time models (T ≥ 0) are Exponential, Weibull, Inverse Weibull, Gamma, Lognormal, normal ( T>0 ; left truncated ) etc. 

In this paper we consider a system that, has two components with independent but non-identical life time probabilities explained by two distinct random variables say T1 and T2 , where T1 has a constant hazard rate and T2 has an increasing hazard respectively

Published: September 2018

Increase in globalization of the industry of software requires an exploration of requirements engineering (RE) in software development institutes at multiple locations. Requirements engineering task is very complicated when it is performed at single site, but it becomes too much complex when stakeholder groups define well-designed requirements under language, time zone and cultural limits. Requirements prioritization (RP) is considered as an imperative part of software requirements engineering in which requirements are ranked to develop best-quality software. In this research, a comparative study of the requirements prioritization techniques was done to overcome the challenges initiated by the corporal distribution of stakeholders within the organization at multiple locations. The objective of this study was to make a comparison between five techniques for prioritizing software requirements and to discuss the results for global software engineering. The selected techniques were Analytic Hierarchy Process (AHP), Cumulative Voting (CV), Value Oriented Prioritization (VOP), Binary Search Tree (BST), and Numerical Assignment Technique (NAT). At the end of the research a framework for Global Software Engineering (GSE) was proposed to prioritize the requirements for stakeholders at distributed locations.
Processo de colonização e políticas desenvolvimentistas do Mato Grosso, Brasil: uma discussão sobre o desmatamento
Authors: Spanholi Maira Luiza , Dos Passos Alessandra Maria Filippin
Published: September 2018

A busca pela colonização de novas terras e a criação de políticas públicas voltadas para o desenvolvimento do Estado de Mato Grosso, Brasil, ocasionaram grande desmatamento de suas florestas, pois priorizavam a exploração dos recursos naturais e a transformação de áreas para a produção de alimentos. Diante disso, esse estudo objetivou trazer uma reflexão sobre a influência do processo de colonização e das políticas desenvolvimentistas no desmatamento no Estado de Mato Grosso. Trata-se de um estudo qualitativo, por meio dede uma revisão bibliográfica nas diversas bases de dados científicos. Historicamente, as políticas públicas voltadas para o desenvolvimento regional priorizaram a ocupação de territórios em detrimento do meio ambiente. No Estado de Mato Grosso, o processo de colonização se voltou para a exploração de recursos madeireiros, tendo em vista a diversidade de espécies na região. Dados tais fatores, o Estado de Mato Grosso representa 20% de todo o desmatamento identificado na Amazônia Legal em 2017.  Pode-se concluir que as políticas desenvolvimentistas implantadas no Estado, preocuparam-se em explorar o seu potencial econômico e recursos naturais para desenvolver a região, tendo em vista retornos econômicos e não atestando a importância da manutenção das florestas.

O estabelecimento de políticas que visem a redução da produção, destinação e a disposição adequada de resíduos, a fim de reduzir os impactos ambientais tem sido evidenciado em todo o mundo neste século. Neste estudo, analisou-se o grau de alinhamento entre a legislação federal e as legislações estaduais e municipais referentes a resíduos sólidos em municípios do mesmo porte de Joinville, Santa Catarina, e investigou-se as práticas sobre planos de resíduos sólidos, coleta seletiva e disposição final nesses municípios. A seleção destes se deu a partir de dados sociodemográficos oficiais, utilizando os seguintes critérios: população, densidade demográfica, índice de desenvolvimento humano e pertencentes a diferentes regiões do Brasil. A análise das legislações estaduais e municipais frente à lei nacional ocorreu por critérios pré-estabelecidos. Os resultados indicaram um desalinhamento nos conceitos entre as legislações estaduais e municipais com a Lei Federal. O enquadramento da lei de Joinville, Santa Catarina foi satisfatório. Evidenciou-se a necessidade de revisão e atualização dessas legislações e práticas que envolvam o gerenciamento de resíduos sólidos, principalmente nos municípios de Juiz de Fora, Minas Gerais e Porto Velho, Rondônia que necessitam se adequar em relação aos prazos estabelecidos em Lei Federal.

Por dentro do caleidoscópio: história e memória político-cultural em Manhã cinzenta, de Olney São Paulo
Authors: Pires Antonia Cristina de Alencar , Tanus Gustavo , Schettini Filipe
Published: September 2018

Neste tempo presente, não há como dissociar arte e política, que se realizam nos mesmos pontos dos textos: na forma ou no conteúdo, ou em ambos. Manhã cinzenta (1969), média-metragem do cineasta baiano Olney São Paulo, é significativo em relação aos engajamentos artísticos e políticos, sendo um dos mais importantes filmes da resistência contra a ditadura civil-militar de 1964, por realizar uma leitura e interpretação do contexto histórico no momento de seu acontecimento, sendo também uma espécie de metáfora da vida do próprio cineasta, afigurando-se como uma ferida em seu corpo estilhaçado pela tortura. Embasamos nossa leitura e análise nos pressupostos teóricos de Marc Ferro (1971; 1992) e de Robert Rosenstone (2010) de que os filmes e os arquivos fílmicos podem suprir a ausência dos documentos oficiais tradicionais, dos quais a história lança mão para construir seu discurso, sendo, portanto, em sentido derridiano, suplementares para a construção historiográfica, podendo ser fontes para a compreensão de contextos e de acontecimentos históricos.
Humor golpista: memes sobre Dilma Rousseff durante o "impeachment"
Authors: Wink Georg
Published: September 2018

Este artigo tem como base um estudo exploratório e preliminar de caso sobre os memes imagéticos de internet que abordaram Dilma Rousseff na ocasião do "impeachment". O objetivo é compreender a sua função humorística, em recorrência a teorias básicas do humor. Parte-se da hipótese que os memes poderiam ser uma nova expressão popularizada da charge política. No entanto, esta abordagem encontra limites, porque o estado da arte ainda carece de um marco teórico contundente e de uma metodologia tecnicamente viável. A análise de uma amostra de memes, representativa pela sua recepção na mídia de massa, evidencia que o seu humor tem tendência para o escárnio, sugerindo superioridade relativa e estimulando agressões recalcadas. Conclui-se, que o principal alvo da crítica humorística desses memes não é a pessoa política, mas o gênero feminino da presidenta, lançando mão do repertório convencional de estereótipos machistas e misóginos.
O manto de aporias: cultura, território e barroco na dinâmica socio-histórica do Estado de Minas Gerais
Authors: Oliveira Anelito Pereira de
Published: September 2018

Este artigo propõe uma interpretação da relação entre literatura e barroco em Minas Gerais, no período que se estende do século XVIII ao XX, a partir da elucidação do antagonismo evidente entre cultura e território, de que a obra atribuída a Antonio Francisco Lisboa, o Aleijadinho, diretamente vinculada à produção da cidade, é referência. Trata-se de exploração de base epistemológica, interessada numa teoria do conhecimento barroco, animada pela premissa de que a complexidade constitutiva do "barroco mineiro" deriva de seu estatuto histórico não exclusivamente artístico, de seu vínculo com a dinâmica social, com a questão urbana nas Minas coloniais. Pretende-se contribuir, sobretudo, para a superação de uma narrativa sobre o "barroco mineiro" esteticista, tanto quanto historicista, que o coloca como capital cultural resolvido, não como problema histórico inscrito na dinâmica sociopolítica brasileira, não apenas mineira.

Comparing responses of the same soil under long-term different treatments is vital in determining the best management practices to conserve soil health and sustain productivity. This study was investigated to determine the effects of longterm (2006-2015) two conventional (CT), three reduced (RT) and a no-till (NT) treatment on bulk density (BD), field capacity (FC), wilting point (WP), available water content (AWC) and total porosity (TP) of a clayey soil in eastern Mediterranean region, Turkey. Undisturbed soil samples were collected from 0-10, 10-20 and 20-30 cm depths of experimental plots with a crop rotation of winter wheat (Triticum aestivum L.), soybean (Glycine max. L.), grain maize (Zea mays L.). The AWC under CT was higher than the RT and NT. The BD was increased with depth in all treatments, and was higher under RT and NT than the CT. The long-term experiment revealed that BD increase under long-term RT and NT should be monitored to avoid deterioration of soil health, and yield loss due to limiting root penetration and storing available water needed during drought periods.

The present investigation aimed to understand the effects of dressing fertilizers and different nitrogen (N) doses on yield and nutrient uptake of chickpea (Cicer arietinum L.) plant. The study has been carried out with three repetitions under the greenhouse conditions. Nitrogen doses were; 0 kg N ha-1, 30 kg N ha-1, 60 kg N ha-1, 90 kg N ha-1 and 120 kg N ha-1 (in CaNO3.4H2O form) and dressing fertilizers were applied as 40 kg N ha-1. The results indicated that the dressing fertilizer application significantly increased average shoot dry weight with 8.18 g poƒ-1. Also, N (2.88 % N), P (0.40 % P), K (3.90 % K) and Fe (114.2 mg kg-1) concentrations increased with dressing fertilizer application of chickpea plant as compared to without dressing fertilizer application. However, dressing fertilizer application did not affect Mg, Zn, Mn and Cu concentrations of chickpea plant. Generally, in this study dressing fertilizer application increased yield and some macro and microelements concentrations of chickpea plant.

Published: September 2018

The aim of the study was to assess the absorbtion degree of different nitrogen forms (ammonium, nitric, amidic) from soil into the plant by using nuclear techniques and 15N isotope as a tracer. In the same time, the effect of foliar fertilization on increasing the efficiency of nitrogen use by biostimulating the plant up-take was highlighted. Urea and ammonium nitrate labeled with 15N isotope (10% from total nitrogen content of the fertilizers being covered by 15N isotope) were incorporated in soil. In order to highlight the efficiency of foliar fertilization, fertilizers having NPK matrix with mezo and microelements and proteic organic compounds (animal and vegetal) were designed and obtained. The effects of experimental treatments on isotopic indicators (15N/14N isotopic rate, δ 15N isotopic accumulation degree, 15N isotope export, absorbtion degree of 15N isotope) from plant were assessed. The tested plant was maize (Cortes hybrid). The values obtained were statistically analyzed by using variance analyze, with two factors, Duncan test of multiple comparison, multiple comparison threshold α= 0.05. The results of agrochemical testing showed that the absorbtion degree of 15N isotope from soil into maize plant was highest for the amidic (N-NH2) form of the nitrogen comparing with the other forms (N-NO3, N-NH4).

Published: September 2018

Wheat, being the main crop in Mediterranean type environments, is grown during winter under rainfed conditions and its yield potential is mostly affected by the amount and distribution of rain. This study is conducted at experimental fields of Ege University, Department of Field Crops in Izmir-Bornova which is characterized as Mediterranean type climate conditions during 2011/2012 and 2012/2013 growing season. Totally 9 canopy structures were generated by different row and line distances. Plant height, total dry weight, tiller number, harvest index, spike number, grain number per spike, thousand grain weight and grain yield were determined after harvest time while digital leaf area index and soil moisture contents were monitoring during specific growth periods to evaluate changes in soil water status by different canopy closer. Increasing in sowing density by different row and in-line distance reduced tiller and spike number per plant. On the other hand, grain number per spike and thousand grain weights were significantly affected by in-line distance instead of row distance. Higher grain yield were obtained from 20x1 cm treatments. Canopy cover speed determined using with digital imaging was not remarkable correlated (r=0.06) with soil moisture content during post-anthesis stage of wheat when higher rain amount is recorded in 2012. However, there was a significant negative correlation (r=0.51) between canopy cover speed and soil water status during post-anthesis stage when the rain amount is limited in 2013. We may suggest that rapid canopy cover lead to negative effect on soil water status via higher transpiration if the rain is limited during post-anthesis stage of wheat.

Published: September 2018

The family Malvaceae includes about 243 genera and at least 4 225 species of herbs, shrubs and trees. They are widely varied and include several important crops, which are mainly used as sources of fibre, food and beverages, medicines, timber. The species of the family Malvaceae: annual, Malva crispa and Malva meluca, native to East Asia, and perennial, Sida hermaphrodita, from North America, grown in monoculture in the experimental land of the Botanical Garden (Institute), served as subjects of the research, and the traditional crop Medicago sativa was used as control. The importance of the studied species of the family Malvaceae consists in their very rapid emergence and fast growth. The analysis of the chemical composition suggested that the dry matter of the studied species, at the 1stmowing contained 15.67-21.67 % raw protein, 2.15-4.46 % raw fats, 8.35-11.53 % minerals and 34.74-40.66 % nitrogen free extract, Medicago sativa - 17.03 %, 2.30 %, 33.31 %, 8.01 % and 39.41 % respectively, making them good candidates for use as livestock feed and for biomethane production. The nutritive value of 100 kg fresh mass of the studied Malvaceae species was 14.9-16.6 nutritive units and 153-173 MJ metabolizable energy, a nutritive unit contained 154.2-191.0 g digestible protein with high concentrations of limiting amino acids, the control - 21 nutritive units, 228 MJ and 164.3 g digestible protein, respectively. The calculated capacity of biomethane production of the studied Malvaceae species can reach 231-267 l/kg organic matter, Medicago sativa - 248 l/kg organic matter. The theoretical ethanol yield from structural carbohydrates of the dry biomass of stalks averaged 437-527 L/t in Malvaceae species, as compared to 485 L/t in corn. The best results were achieved by Sida hermaphrodita, due to its high amount of structural carbohydrates. These species may serve as feed for livestock, but also as multi-purpose feedstock for biorefinery in Moldova.

Paulownia ssp., in its places of origin, has been cultivated for over 2600 years and used as protection curtains against sand storms or floods, studies of how this species was exploited only fifty years ago in time what genetic research has only been affected in the last thirty years. The fundamental purpose of experimentation was to check the influence of different technological links (planting density and fertilization scheme), not only on the weight of the wood and the technological characteristics of the wood obtained, but also on the total biomass accumulation. The objectives of the research were: a) stems diameter increase, measured at 100 cm height from the soil surface, maintaining the harvest variant at 4 years; b) increasing of biomass accumulation. In all experimental variants, it is noted that the plants recorded higher values of the different variables analyzed (diameter at the base, normal diameter and total height), when the fertilization factor also intervenes. In the same way, when a higher fertilization was applied, higher values of the dendrometric indicators are obtained compared to the experimental variants that did not benefit from the supplementation of nutrients, suggesting that the most important risk factor in Paulownia plantations is the planting density and the fertilization element.

Published: September 2018

The draught phenomena affecting the traditional agricultural areas in south of Romania has been increasing in intensity over the time, leading to the desertification of several thousands of hectares in the south part of the country. In this study we have computed the vegetation fraction cover for the South-West and South - East regions of Romania, based on the minimum and maximum NDVI extracted from MODIS satellite images. The time frame to refer to is 2000 - 2017, perennially, with special significance given the numerous and prolonged draught intervals these areas have been facing and the social economic evolution, from small farms to large agricultural holdings. The resulted vegetation fraction cover (fc) is correlated to the SPI values in order to determine a pattern to be used in anticipating deviations from the seasonal vegetation productivity. As a conclusion, the study presents a fair balance, indicating the most sensitive areas in soil vegetation cover, due to the SPI change.

Authors: Ciopașiu Roxana Mihaela , Berbece Elena Florina , Ioniță Mariana , Mitrea Ioan Liviu
Published: September 2018

The lungworm Aelurostrongylus abstrusus (Nematoda: Angiostrongylidae) is a parasite of domestic and wild felids with worldwide distribution. The parasite lives in bronchioles and alveolar ducts, and its presence is associated with respiratory clinical signs. Cat lungworms are still considered by many clinicians sporadic and rarely are taken into account in the cat pathology. Therefore, in this paper we present a clinical and epidemiological study on cats with natural A. abstrusus infection. For this, 131 cats, with exclusive outdoor or outdoor and indoor access, of different gender (49 males, 82 females) and age (between 2 months and 11 years), from Southern and Center Romania, were included in the study. Of them, individual fresh faecal samples were collected and analyzed to identify first-stage larvae (L1) of lungworms, using a Baermann technique, and eggs/oocysts of other endoparasites, by a flotation method. Subsequently, of the examined samples, 6.10% (8/131) were positive for A. abstrusus. The positive cats aged between 3 months and 2 years. Of them, 3 cats were co-infected: two with Toxocara cati and one with Ancylostoma tubaeforme. Clinically, 75% (6/8) of the infected cats displayed respiratory signs varying from mild (sporadic coughing, sneezing) (n=3) to severe symptoms (mucopurulent nasal discharge, abdominal breathing) (n=3), while 25% (2/8) showed no respiratory signs. The three cats with severe respiratory disease were infected only with A.abstrusus. In conclusion, veterinary practitioners should include Aelurostrongylus infection in the differential diagnosis of catʼs respiratory pathology.

Published: September 2018

The aim of this paper was to present a histological evaluation of the treatment performed on a humanmodel of osteomyelitis induced in rabbits. Osteomyelitis was induced in rabbits by a human strain of Staphylococcus aureus injected in bone defects created in the rabbit tibia. There have been created five groups of animals, groups receiving treatment in two different stages of the disease, acute and chronic. Copper and silver sub-millimetre-particles were introduced in the same place with the Staphylococcus solution. Evaluation of installation and evolution of the disease was done by clinical, hematological, microbiological, radiological and histological monitoring. A separate study of histological data is presented here. Histological examinations performed by HE was done on 5 μm sections of uncalcified bone. Every examination was classified according to a system of score. The results of histopathological evaluation confirm that histological analysis is a powerful tool in experimental models of this disease.

Published: September 2018

Our bibliographic insights have shown that although thermographic imaging in small animals has been poorly studied, the empirical use of thermographic images in dogs suggests that thermographic imaging could be a useful method in assessing walking anomalies. The study aims to identify existing thermal asymmetries between the thermal paw prints of the hind limbs in healthy dogs (right versus left). For thermal investigations, the Flir E50 thermal camera with a resolution of 240×180, thermal sensitivity of 0.05ºC, 45º×34ºA visual field and unbalanced microbolometer was used. Acclimatization of the animals in the space for examination was 30 minutes (at a room temperature of 20-23°C). The resulting images were recorded, processed and analyzed with the Flir tools 2017 software. The average, maximum and minimum temperature of each image was calculated using the program. The results obtained show that between the thermal paws marks of the posterior limbs in healthy dogs there is an average thermal asymmetry comprised between 0.2 and 1.4°C. Our study suggested that, under controlled conditions, thermographic paws prints could be used to diagnose locomotor abnormalities in dogs..

Published: September 2018

The experiment was carried out on four groups of Hy-Line var. Brown hens (n = 350 each) fed on diets which provided 2.49, 3.07, 3.78 and, respectively, 4.15 g% calcium (Ca) during the laying period. Consequently, mean daily Ca intake was 2.74, 3.38, 4.16 and 4.60 g/cap., respectively. Ca metabolism was assayed at 20 weeks of age (start of the laying), 36 weeks of age (the peak of the laying) and 68 weeks (the end of the laying period). A significant part of the ingested Ca was not absorbed. The percentage of Ca exonerated by feces was higher at the start of the laying and lowers in the peak of laying and at the end of the laying period. The amount of Ca exonerated as unabsorbed Ca increases as the amount of ingested Ca increases inside of each age level. It was found also an increase of the Ca content of the egg shell according the Ca intake statistically significant (P<0.05) in 36- and 68-wk.-old hens, but not in 20-wk.-old hens. Blood plasma Ca showed significantly higher values in 3.38-, 4.16- and 4.60-g/day-Ca-intake groups when compared by 2.74-g/day-Ca-intake group (P < 0.05) but the level of increasing showed lowest values in hen groups with highest intake of Ca. The daily eggshell Ca export strongly correlates with the amount of daily Ca intake in 36-wk.-old hens and 68-wk.-old hens: r = +0.72 and +0.84, respectively, but no correlation was found in 20-wk.-old hens (r = -0.74, negative correlation). The results showed a limited physiologic capacity of the Ca absorption in hen, the Ca surplus being lost. Dietary Ca level should be closely correlated with the laying level of hens.

Published: September 2018

Bisphenol A (BPA) is a compound that is released from PET packaging during storage bottled water and can have a harmful effect on human health. This study aimed to investigate the cytotoxic potential of BPA at the Caco-2 cell line. Bottled water samples coming from two companies were analyzed starting from 1 month to 12 months of storage Quantification of BPA in water stored in PET containers was carried out by a spectrometric method. Calibration was performed for BPA concentrations ranging between 0.01 and 0.09 mg/L. Caco-2 cell cultures were treated for 24 hours with different BPA concentrations (from 0.1 mM to 1 mM). Viability and cell cytotoxicity analysis was performed by MTT assay. BPA concentration in one water sample ranged from 0.09 to 0.92 mg/L while for second water sample BPA concentration ranged from 0.03 to 0.73 mg/L. After 10 months from packing, BPA concentration began to exceed the 0.6 mg/L limit stated by Regulation (EU) no. 10/2011. Cell viability decreased in a dose dependent manner and reached the minimum of 3.8% for the 1 mM BPA concentration.

Published: September 2018

In the last decade there is an increased interest in selecting photosynthetic microorganisms with higher lipid content useful for biotechnological applications. In this paper we present our original results concerning: i) the selection of naturally occurring photosynthetic microorganisms with higher lipid content; ii) the use of these isolates as biological material subject of randomly induced mutagenesis; iii) selection by iodine vapour method of clones with decreased polysaccharides content and expected higher lipid content) as well as iv) genetic analysis of most promising strains in order to check the if they are true mutants or not. The results thus obtained argue the importance of the selection of naturally occurring photosynthetic microorganisms with higher lipid content as well as the use of random mutagenesis as a valuable tool to improve the genetic diversity of photosynthetic microorganisms in order to increase their ability to synthesize lipids for further biodiesel production and/or omega 3 or 6 production.
