Authors: Souza Geraldo da Silva e , Gomes Eliane Gonçalves , Gazzola Rosaura
Published: March 2021

O objetivo do trabalho é estudar a presença da agricultura e/ou pecuária orgânica na renda dos estabelecimentos agropecuários recenseados em 2017. A análise está baseada nos dados agregados em escala municipal. Caracteriza-se regionalmente a presença da produção orgânica por meio de tabelas de contingência, via qui-quadrado e análise de covariância, tomando-se como variáveis contextuais: regiões, classes de renda, área, assistência técnica, cooperativismo, alfabetização, crédito e área. Ajusta-se, também, uma fronteira de produção estocástica que identifica, em nível do município, o efeito de fatores que afetam diretamente a produção (renda bruta) e a componente de ineficiência técnica. O número de estabelecimentos que praticam agricultura e/ou pecuária orgânica diminuiu de 90.498 (em 2006) para 64.690 (em 2017). A predominância de agricultura orgânica está no Sudeste e a menor proporção está no Centro-Oeste. A classe de renda bruta predominante para os estabelecimentos que praticam pecuária e/ou agricultura orgânica, em todas as regiões, é a classe entre zero a dois salários mínimo. O acesso ao crédito, a associação em cooperativas, o nível de alfabetização e o acesso à assistência técnica são os principais fatores necessários para promover a melhoria da renda. Os fatores de produção fundamentais para a inclusão produtiva são tecnologia e trabalho com dominância da tecnologia.

Published: March 2021

BACKGROUND Fistula-in-ano or anal fistulas are documented since ancient times and their management has always been a challenge. Various modalities of treatment are available and newer ones are being added each day. The aim of this retrospective study is to analyse the outcome of the video assisted anal fistula treatment (VAAFT), one of the modalities of treatment for complex anal fistulas done at our centre. METHODS Records of patients who had been treated through VAAFT by single senior consultant surgeon of Minimal Access Surgery unit between April 2013 and March 2019, were collected and analysed. RESULTS Altogether, records of 48 (forty-eight) patients who had undergone VAAFT during the period were analysed. Data revealed that 38 male (79.17 %) and 10 female (20.83 %) patients with mean age of 49.96 ± 12.22 years were operated. Most commonly, trans sphincteric followed by inter sphincteric type of fistulae were encountered. In 3 cases, internal opening couldn’t be visualised. Six patients were documented to have a recurrence within 6 months of the procedure and in the rest were cured except in a small subset of patients who did not follow up. CONCLUSIONS Amongst the wide range of armamentarium available today for the treatment of complex anal fistulas, video assisted anal fistula treatment (VAAFT) is a novel sphincter saving technique. The recurrence rate at our centre was at par with other studies and with zero incontinence rate, however further RCTs are required.

Published: March 2021

BACKGROUND Reduced heart rate variability (HRV) is associated with an increased risk of cardiovascular morbidity and mortality. The aim of the study was to determine whether reduced HRV is predictive of angiographic coronary artery disease (CAD) METHODS This study was done among 71 clinically stable subjects who underwent elective coronary angiography for diagnosis or pre-operative evaluation. High frequency (HF; 0.15 – 0.40 Hz), low frequency (LF; 0.04 – 0.15 Hz), LF / HF ratio, total power ≤ 0.4 Hz were used as the conventional indices of HRV. Analysis of variance (ANOVA) and chi square test was used to assess the statistical analysis. Statistical significance analysis was carried out with International Business Machines Statistical Package for the Social Sciences (IBM SPSS) version 22. RESULTS Out of 71 subjects, only 58 were available for final analysis. 20 subjects had normal coronary arteries, 19 had single vessel disease and remaining 19 had multi vessel disease. The HF power of HRV showed decreasing trend as the severity of angiographic stenosis increased. The median values of LF power for single vessel disease and multi vessel disease were 148 ms2 and 160 ms2 respectively. The group without coronary artery disease has a median of 215 ms2 for LF power. The median HF power was lower in single vessel disease group (133 ms2 ) compared to group with normal coronaries (139 ms2 ) and it was very low in multi vessel disease (81 ms2 ) group compared to group with normal coronaries. CONCLUSIONS A weak association of HF and LF power of HRV with degree of angiographic stenosis was observed. KEYWORDS Heart Rate Variability, Coronary Angiogram, Angiographic Stenosis
Prospective Study of Central Venous Pressure Trends during Major Neurosurgical Procedures in an Elective Operation Theatre Setting of a Tertiary Care Centre
Authors: Sarojini Rajeev Damodaran , Sahadevan Sanjay , Christhudas Jayakumar
Published: March 2021

BACKGROUND There are extensive variations in central venous pressure during intraoperative period of a major neurosurgical patients. Monitoring of central venous pressure is vital for guiding the administration of fluids, blood and blood products. Central venous pressure (CVP) also measures the intracranial pressure indirectly. Increased intracranial pressure thereby reduces the cerebral blood flow, leading to cerebral ischemia. METHODS This is a prospective study where 25 major neurosurgical cases posted for elective major neurosurgery were selected. Right subclavian vein was selected for cannulation, by blind technique in all these cases. CVP was recorded every 15 minutes. Central venous catheter was connected to a pressure transducer linked to a multichannel monitor; zeroing was done and the CVP reading obtained. RESULTS Central venous pressure reading was done serially and showed the trends in haemodynamics in various stages of surgery. Initial intraoperative periods showed lower values due to intravenous (I / V) induction of anaesthesia, use of mannitol and diuretics. Later on, the trends changed to higher side subsequent to administration of fluids and blood as required. CONCLUSIONS Monitoring of CVP is an important component of haemodynamic monitoring along with non-invasive blood pressure (NIBP), intra-arterial blood pressure (IABP), and urine output. Central venous pressure can be used to aspirate an air embolism occurring during the intraoperative period after employing Durant’s position.

O presente artigo tem como intuito  trazer as informações a respeito dos objetivos do desenvolvimento sustentável (ODS) que surgiu em 2015 graças ao sucesso dos objetivos de desenvolvimentos do milênio (ODM), que teve inicio em 2000, falando especificamente da meta 4.2 que se refere à qualidade do ensino na primeira infância, que é onde o individuo tem o primeiro contato escolar, e ao preparo de crianças para os anos iniciais do ensino fundamental e como esse preparo é feito, foram utilizados pesquisas bibliográficas, pesquisas de campo e entrevistas com professores e pedagogas de duas instituições de ensino uma publica e outra particular. Os resultados obtidos foram as divergências entre as duas instituições onde a particular executa o preparo com foco na alfabetização já a publica respeitam as leis municipais que proíbe a antecipação de conteúdo. Conclui-se que as informações obtidas a respeito da educação nos dias de hoje demonstram que a instituição particular tem um preparo precoce para a pré-alfabetização, já a instituição publica respeitando normas municipais, dá assim um preparo psicológico para o individuo, notou-se que os profissionais de educação em sua maioria não tinham conhecimento sobre os objetivos do desenvolvimento sustentável (ODS), em relação à educação.

Published: March 2021

Os professores de Matemática do sexto ano escolar da rede de ensino municipal de Criciúma - localizada no estado brasileiro de Santa Catarina - têm identificado nos estudantes lacunas em relação aos conceitos ensinados nos anos escolares anteriores. Para esses professores, a maioria dos estudantes do início dos anos finais do Ensino Fundamental (EF) apresentam equívocos conceituais em situações relacionadas, principalmente, à multiplicação e à divisão. Nossa hipótese é que esses problemas da não apropriação, pelos estudantes das significações conceituais de Matemática, estão relacionados ao conhecimento empírico adotado para a organização do ensino. Com a finalidade de abolir as lacunas na aprendizagem de Matemática, nos estudantes, desenvolveu-se um projeto de extensão. A questão investigada foi: quais as contribuições de uma formação de professoras dos anos iniciais para reelaborar a organização do ensino de multiplicação e divisão, com base nos fundamentos do sistema de Elkonin-Davydov? Para a análise dos dados foram transcritas as falas das professoras que foram gravadas durante os encontros mensais. A partir das discussões realizadas na formação, as professoras constataram que no sistema de ensino de Elkonin-Davydov a multiplicação e a divisão possuem os mesmos elementos conceituais no contexto da medição de grandezas com base em duas unidades: básica e intermediária, mas com finalidades distintas. Essa constatação supera o modo de ensino fragmentado dessas operações, realizadas por elas, anteriormente a participação no projeto de extensão. Além disso, foi identificada a relação dos elementos da multiplicação em consonância com os fundamentos da Matemática.

Cancelamentos de Cirurgias Eletivas no Próprio Dia da Operação num Hospital Português: Um Ano em Perspetiva
Authors: Ferreira Joaquim , Boto Paulo
Published: March 2021

Introdução: Os cancelamentos de cirurgias eletivas que ocorrem no próprio dia da cirurgia acarretam importantes consequências clínicas, sociais e económicas, individuais e familiares, mas também institucionais, e refletem processos de eficiência e qualidade das organizações. Este estudo pretende avaliar a dimensão dos cancelamentos no dia da cirurgia numa instituição do Serviço Nacional de Saúde, quantificando-os, identificando as causas, origem e previsibilidade, na relação com variáveis sociodemográficas e intervenções dedicadas à sua redução.Material e Métodos: Metodologia quantitativa descritiva, de abordagem não experimental, longitudinal e de dimensão temporal retrospetiva, relativa aos episódios com cancelamentos cirúrgicos no dia da cirurgia, decorridos no período compreendido entre 1 de janeiro e 31 de dezembro de 2018.Resultados: A taxa de cancelamento no próprio dia foi de 2,9%, variando entre as especialidades cirúrgicas, maioritariamente em doentes do sexo feminino, na faixa etária dos 50 aos 80 anos, com estado físico II ou III, segundo a American Society of Anestesiology, e sem consulta pré-anestésica ou pré-operatória prévias; as três causas de cancelamentos mais evidentes são: a falta de tempo operatório, a falta de camas e/ou materiais e a alteração do estado de saúde, a maioria das quais evitáveis e imputáveis à instituição.Discussão: Os múltiplos motivos de cancelamento refletem uma variedade de processos a montante e a jusante, que culminam no cancelamento cirúrgico, e cuja a origem/imputabilidade se dispersa entre a instituição e o próprio doente.Conclusão: A taxa de cancelamento de cirurgias eletivas no próprio dia da operação é relativamente baixa, mas as causas são frequentemente evitáveis, justificando a generalização de estratégias de redução dos cancelamentos.

Published: March 2021

Today, media digitalization has become the foundation of media industry owners in presenting a variety of information and entertainment, including media television. With the establishment of various commercial television broadcasting institutions as well as the competition for the media competition which is quite tight. Seeing the development of television broadcasting media itself with heavy competition, Islamic television institutions, in particular, seem not ready to compete with other television institutions. Institutions that affect the unpreparedness of existing Islamic television broadcasting institutions are planning and strategy within Islamic television broadcasting organizations and institutions, both before they come to the process of running and maintaining broadcasting institutions for a long period of time. The research method used is library research with in-depth analysis to explore problems related to the theme. The results of this study indicate that there are several things that must be planned before deciding to determine an Islamic television broadcasting institution; a) planning human resources, b) planning institutions, c) planning a product or program. When an Islamic broadcasting institution plans well, the sustainability of the Islamic broadcasting institution can be managed and run for a long time. That way, the existence of Islamic television media is indirectly able to provide another option for the public in enjoying the broadcasts that are served.
The Black Lives Matter movement and health inequalities
Authors: GANGOPADHYAY JAGRITI
Published: March 2021

With the recent Black Lives Matter movement, existing racial inequalities in various sectors of the United States have regained prominence. Due to the pandemic, statistics on racial disparities in the health sector have been aggravated. On a related note, while the #Black Lives Matter movement received substantial support from India’s online community, deeply entrenched inequalities in terms of caste, community and gender in India’s health sector need to be critically evaluated as well. This paper is an attempt to understand how the awareness generated by the Black Lives Matter movement could be an opportunity to address structural inequalities in India’s own public health system.
New Dimension of Global Energy Security
Authors: Telegina E.
Published: March 2021

The article analyzes the current state of energy markets. The basic fundamental factor of the demand for energy resources – the world economy growth – is rather low. At the same time, the USA and China demonstrate steady economic growth, thus rising demand for hydrocarbons. But recent decline of prices for oil and other commodities like metals or grain shows that among various factors, both fundamental and speculative, financial markets are also speeding up the volatility on the markets, thus deepening the gap between “paper” and “fair” oil price. Also, it is necessary to analyze the impact on the situation on the global oil market of such multidirectional factors as influence of “shale revolution” in the USA or Saudi Arabia refusal to reduce oil production. Shale oil helped USA to overcome oil import dependency and to become an exporter in the future. However, production costs in the country are rather high. On the contrary, Saudi Arabia has low production costs and is now trying to keep the international prices at a level that makes the US shale projects infeasible. The Saudi budget 2015 assumed a price of $90/barrel and it can endure $50 as well. However, other oil exporting countries face huge losses. Nevertheless, in the future oil prices will rise and evidently the level of fair price can be determined at $60-70/barrel. The author examines also the break-even prices for oil production and levels of oil prices necessary for formation of budgets of oil exporting countries. The changes on oil and gas markets lead to formation of more complicated global energy space and to shifts in the concept of energy security from ensuring the stability of energy supplies to energy self-sufficiency. The transformation of energy markets and geopolitical risks cause the changes in the transportation logistics and enhance risks of implementation of new trans-border pipelines. Prospects of sustainable and multidirectional development of global and regional energy markets are also considered.
Erosion of “Swedish Model” and Devaluation of the Non-Alignment Policy
Authors: Voronov K.
Published: March 2021

The erosion of the socio-economic “Swedish model” and the reduction of non-alignment in the national foreign policy have been and is taking place in history and politics simultaneously, exerting a fatal mutual interaction. The derived deviations are leading to a radical alteration of Sweden’s image, of its previous national and international specificity. The degradation of the “Swedish model” has been taking place as a result of activity of intrinsic forces and factors closely connected with structural social problems, matters of national economy efficiency and adaptation to world economy requirements, to processes of globalization. The general destructive transformation, a big number of qualitative doctrinal and institutional changes taking place since 1990s till now in the framework of the “Swedish model” is also linked with the condition of internal strife and alignment of political party forces in the country, aiming at finding an adequate answer to new challenges of the 21st century. The events of Ukrainian crisis (particularly concerning Crimea and Donetsk Basin) apparently influenced Sweden, politically resounding with a known painful historical “Poltava syndrome”. Although the incorporation of Sweden (as well as that of other small Nordic states) in European regional and Nordic sub-regional integration processes reflects the principal objective economic trend to internationalization of the world economy, the forms, rates and prospects of political integration into the EU sometimes generate objections, resistance and even disapproval of state institutions by a part of society in connection with external as well as internal socioeconomic reasons (particularly in terms of the “Swedish model” acute agenda). The loss of the famous features of Sweden’s international policy, especially after its accession to the European Community/European Union, as well as its leveling led to the loss of the original political role of the country in the Northern sub-region and in Europe at large. Immanent undermining, washing out of fundamental guarantees in the Swedish policy of neutrality pushes Stockholm forward to shameless convergence with Euro-Atlantic partners and their alliances – the EU and NATO. To all appearances, a complicated search is going on in the country – the search of a new socioeconomic model, of the foreign policy and the national security policy modification.
Euro Factor in the External Trade of the Eurozone Countries
Authors: Polivach A.
Published: March 2021

The author investigates the influence of the single European currency on the external trade performance of particular members of the Eurozone. It is analyzed on the basis of IMF’s statistics on real effective exchange rates of the Euro for every Eurozone’s member and their external trade dynamics in the periods before and after introduction of the Euro. The author points out that, even though with the national governments lost an ability to pursue own exchange rate policy, they still implement independent financial, economic and labor policies. The discrepancies in these policies determine the value of the Euro’s real effective exchange rate calculation for particular members. Respectively, the modern days’ external trade competitiveness of a particular member state is predicated upon the effectiveness of the above-mentioned policies and their succession with the pre-Euro era policies. The author concludes that widespread idea that Germany is the only beneficiary from the Euro’s introduction while other Eurozone members are the losers is ill-based. Also, while researching statistical data for this article it was discovered that the figures of mutual trade between the Eurozone member states are not quite compatible despite the fact that there are no trade barriers and that the customs statistics methodology has been harmonized inside the Eurozone. According to available statistics, in many cases the exports from one member state substantially exceeded respective imports of another member. According to statistical methodology the situation should look vice versa due to exports’ valuation in fob prices and imports’ – in cif ones that normally exceed them. This circumstance makes extremely difficult a persuasive statistical verification of any hypothesis about influence of the Euro on the external trade of the Eurozone members.
A ’Local-Global’ model for Seasonal Diseases: Influenza Subtypes Analysis Case Study
Authors: almogy gal
Published: March 2021

Influenza epidemics in temperate regions display dynamics that are characterized by pronounced seasonal peaks during the winter. The general lack of influenza cases during the off-season may result from the virus physically disappearing at the end of the season, in which case it must be imported annually. Alternatively, it may result from persistent asymptomatic carriers or unnoticed local transmission chains that develop into local epidemics as conditions become conducive. Here I attempt to understand these differing explanations by analyzing the global distribution of the four major subtypes that comprise influenza over a period of 18 years based on FluNet data, the surveillance network and database compiled by the WHO, and the NCBI influenza data resource, a repository of relevant genetic information. Examining the annual proportion of each subtype, I find considerable variations in subtype annual proportions between the regions. Moreover, I find that seasonal influenza subtypes can remain confined to specific temperate regions, without showing measurable global presence. These results indicate that although largely undetected during the off-season, influenza is likely to persist locally, and imply a ‘local-global’ model where annual influenza epidemics are a mixture of local strains undergoing reactivation together with an influx of global variants.

Dermal wound healing describes the progressive repair and recalcitrant mechanism of damaged skin and eventually reformatting and reshaping the skin. Many probiotics, nutraceuticals, metal nanoparticles have been associated with improved healing process of intra and inter tissue wounds. Despite the vast nature on material based wound healing mediators, the exact mechanism on material-cellular interaction is still point of repent issue particularly in diabetics and pathological condition. The use of bioengineered alternative agents will likely only continue to dominate the outpatient and perioperative management of chronic, recalcitrant wounds as new additional products continue to cut costs and improve wound healing process. This review article provides an update of the various remedies with confirmed wound healing activities by a diverse group of agents from previous experiments conducted by various researchers
From the Cottage to the Cage – Exploring the Efficacy of Complexity Leadership Theory in Addressing 21st Century Workplace Toxicity.
Authors: Danaher Morgan
Published: March 2021

The issue of workplace toxicity constitutes a major problem for employers, employees and society at large. Toxicity in a workplace context relates to damaging behaviours perpetrated by individuals and organisations that netatively impact on the health and wellbeing of others. Workplace toxicty is habitually associated with activities such as bullying, harrassment, unethical and even illegal acts. In this article, today’s workplace is likenened to a cage where ambition and greed drive people to engage in toxic behaviour to fight for whatever scarce rewards are on offer. Set against a backdrop of continuous demands on employees in a era of constant change and challenge, leadership practice in the 21st century is understandably seeped in complexity. Whilst conditions of scarcity are in fact constructed by employers in today’s lean environments, workplace toxicity has significant implications for organisational leaders in terms of work place disputes, absenteeism and litigation etc. Twentieth century hierarchial and autocratic leadership models are now deemed to be both obsolete and wholly inadedgate to inform leadership practice in the knowledge era. This conceptual article looks at the efficacy of complexity leadership theory (CLT) in empowering today’s leader to better understand and address 21st century workplace toxicity.

Authors: Moore M , DeHaan L , Ehrenberg T , Gross L , Magembe C
Published: March 2021

Objective: To describe several clinical tests and predisposing factors for shoulder impingement syndrome in violin and viola players. Subjects: Ten musicians (7 females, 3 males) and 18 controls (8 females, 10 males), all college-aged. Methods: Subjects were interviewed
about their music-playing history and shoulder pain. Four clinical assessment tests were performed on both shoulders: Neer impingement text (maximal flexion +/- pain), shoulder internal rotation with over-pressure (end-feel and +/- pain), lower trapezius muscle strength (ft-lbs of torque from
manual dynamometer), and forward shoulder posture (height of acromion from plinth with subject supine). Analysis: Descriptive analysis of questionnaire data, plus two-sample t-tests for manual shoulder assessment tests in musicians versus controls. Also comparisons of music-playing
history in musicians with and without shoulder impingement. Results: Seventy percent of musicians reported pain somewhere in the upper limb, with 50% in the left shoulder and 30% in the right shoulder. Thirty percent of musicians had a positive Neer impingement test, while 0% of controls
did. There was a significant phi (Φ) correlation between being a musician and having a higher incidence of shoulder impingement (p<0.01 for bowing arm, p<0.05 for left arm). Those musicians with a positive impingement test also had pain with over-pressure in internal
rotation, indicating a chronic condition. Musicians' mean playing time was 9.8 hr/wk, with 14 min/hr of rest. Musicians with impingement tended to play more hours per week, but differences in playing time and rest were not significant. t-Tests showed no significant difference in lower
trapezius strength or degree of forward shoulder between musicians and controls. Conclusions: Upper string players are at increased risk for shoulder impingement.

Your editorial in the September issue suggested undertaking new research on the prevalence of disorders among music students in colleges. This research could bring us still more tangible data on their incidence in performing artists (even though it would not be representative of the
most numerous, also affected, but research-wise quite neglected part of the music-making and ballet-dancing population: the beginner students). I wholeheartedly welcome your suggestion, as I welcome any effort which could influence a major shift in attitude among my fellow teachers.

Limited data are available on whether different physical fitness levels are associated with injury severity in contemporary dancers. The aim of this study was to investigate this association in female dancers. Five professional contemporary dancers and 11 dance students in pre-professional
training volunteered (n = 16). All participants underwent selected fitness assessments (anthropometry, flexibility, muscular power and endurance, aerobic capacity) and completed a seven-item recall questionnaire about their last 12-month injury history. Pearson's coefficients detected
significant negative correlations between the total number of days off due to injuries and standing vertical jump (r = –0.66; p = 0.014). Backward regression analysis also revealed that days off due to injuries was best predicted from standing vertical jump performance
(p = 0.014). Results suggest that a reduced level of lower body muscular power is associated with increased severity of injuries in female contemporary dancers. More research using appropriate methodological designs, such as sample size calculations and randomization and the use of
contemporary dance movements only, is needed to investigate the effects of physical fitness levels on injury severity in contemporary dance.
Toward a Performing Arts Medicine Definition of Performing Arts
Authors: Manchester Ralph A
Published: March 2021

As the Performing Arts Medicine Association (PAMA) celebrates its 20th anniversary this year, it seems to be a good time to discuss a definition of what the field includes—and, by extension, what it doesn't include. Some may think that this might not be the best use of our time,
since we have done pretty well so far without a written definition of the performing arts. However, a presentation at the 27th Annual Symposium on the Medical Problems of Musicians & Dancers on health issues of circus performers and some recent articles in Medical Problems of Performing
Artists on artistic and rhythmic gymnasts have helped us broaden the scope of our field. While I find this exciting and another indication that performing arts medicine is a vibrant, essential specialty within the universe of health care, it also makes me wonder what else ought to be included
in the field and what shouldn't.

Published: March 2021

This article reports on the experiences of a rheumatologist, newly added to the staff of a Dutch performing arts medicine clinic, in his first year of part-time work. In the year May 2007 to May 2008, 253 consecutive new patient-musicians seen by the author. Patients were predominantly
male (135 vs 118) with a mean age of 39 years (range 12 to 78). Amateurs accounted for 35% of the referrals. Keyboard players, guitarists, and violinists predominated. The main complaints involved the upper extremity, with the hand being the most common, followed by the shoulder and wrist.
Among specific complaints, 15% of patients presented with primarily neurologic complaints, 12% with trauma, 8% osteoarthritis, 7.5% rotator cuff syndromes, 7% wrist ganglion, 7% tendon problems, and 4% focal dystonia. Treatment approaches are summarized.

The current study deals with the performance of constructed wetland (CW) incorporating a microbial fuel cell (MFC) for wastewater treatment and electricity generation. The whole unit is referred to as CW-MFC. This technique involves two treatments; the first is an aerobic treatment which occurs in the upper layer of the system (cathode section) and the second is anaerobic biological treatment in the lower layer of the system (anode section). Two types of electrode material were tested; stainless steel and graphite. Three configurations for electrodes arrangement CW-MFC were used. In the first unit of CW-MFC, the anode was graphite plate (GPa) and cathode was also graphite plate (GPc), in the second CW-MFC unit, the anode was stainless steel mesh (SSMa) and the cathode was a couple of stainless steel plain (SSPc). The anode in the third CW-MFC unit was stainless steel mesh (SSMa) and the cathode was graphite plate (GPc). It was found that the maximum performance for electricity generation (9 mW/m3) was obtained in the unit with stainless steel mesh as anode and graphite plate as cathode. After 10 days of operation, the best result for COD removal (70%) was obtained in the unit with stainless steel mesh as anode and stainless steel plain as cathode. The effect of temperature was also investigated. The performance of unit operation for electricity generation was tested at three values of temperature; 30, 35 and 40oC. The best result was obtained at 40oC, at which the current density obtained was 80 mA/m3. A culture of Algae could grow in the unit in order to supply the cathodic region with oxygen.
New algorithms to Enhanced Fused Images from Auto-Focus Images

Published: March 2021

Enhancing quality image fusion was proposed using new algorithms in auto-focus image fusion. The first algorithm is based on determining the standard deviation to combine two images. The second algorithm concentrates on the contrast at edge points and correlation method as the criteria parameter for the resulted image quality. This algorithm considers three blocks with different sizes at the homogenous region and moves it 10 pixels within the same homogenous region. These blocks examine the statistical properties of the block and decide automatically the next step. The resulted combined image is better in the contrast value because of the added edge points from the two combined images that depend on the suggested algorithms. This enhancement in edge regions is measured and reaches to double in enhancing the contrast. Different methods are used to be compared with the suggested method.

Background

Fatty liver disease prevalently occurs in commercial postpartum dairies, resulting in a worldwide high culling rate because of their subsequent limitations of production and reproduction performance.
Results

Fatty liver-specific proteome and acetylome analysis revealed that energy metabolism suppression closely associated with mitochondrial dysfunction and inflammation activation are shown to be remarkable biological processes underlying the development of fatty liver disease, thereby acetylation modification of proteins modulating these processes. Twenty pivotal genetic factors/genes that differentially expressing and being acetylation modified in liver were identified and proposed to regulate the pathogenesis of fatty liver dairies. These proteins were confirmed to be differentially expressing in individual liver tissues, eight of which being validated through immunohistochemistry assay.
Conclusion

This study provided a comprehensive proteome and acetylome profile of fatty liver of dairy cows, and revealed potential important biological processes and essential regulators in the pathogenesis of fatty liver disease. Expectantly, understanding the molecular mechanisms of the pathogenesis of fatty liver disease in dairies, as an animal model of non-alcoholic fatty liver disease (NAFLD) in human beings, which is a clinico-pathologically defined process associated with metabolic syndrome, could inspire and facilitate the development of efficacious therapeutic drugs on NAFLD.

Published: March 2021

In recent years, the important energetic material triaminoguanidinium nitrate (TAGN) has been widely used, and the process of synthesizing TAGN has become more and more perfect. However, there are relatively few theoretical studies on TAGN. This paper uses first-principles calculations to more systematically study the crystal structure, electronic, vibrational and thermodynamic properties of TAGN. The calculation results show that the calculated unit cell parameters are relatively consistent with the values obtained through X-ray diffraction experiments. This article describes in detail the state density of the valence electron of each atom. By analyzing the vibrational properties of TAGN crystal, the vibration mode corresponding to each optical wave is obtained. At the same time, the vibration mode of each peak in the Raman spectrum and the infrared spectrum is described in detail. Then the calculated value is compared with the experimental value, it can be seen that the error is relatively small. According to the vibration characteristics, a series of thermodynamic functions such as enthalpy (H), Debye temperature (Θ), free energy (F), and entropy (S) are calculated. These thermodynamic functions can provide a certain reference for future research.
