Authors: Akgul Dogan , Kirkar Safak Metin , Onal Busra Selenay , Celen Ali , Dalkilic Ahmet Selim , Wongwises Somchai
Published: February 2022

The aim of this review is to present a summary of the published papers of the heat transfer and pressure drop characteristics for single-phase flow in helically coiled tubes. The effect of geometrical parameters such as curvature ratio, coil pitch and working conditions such as Reynolds number, Dean number, flow rate and flow arrangement on heat transfer and pressure drop in helically coiled tubes are determined in the light of the experimental, numerical and analytical studies in the literature. Also, the effect of using nanofluids in comparison with conventional fluids, using enhanced surfaces such as corrugated, micro-finned, dimpled with regards to smooth surfaces and wire coil insert usage in helically coiled tubes are discussed. The correlations proposed for determination of Nusselt number and friction factor in helically coiled tubes are presented in detail separately under laminar and turbulent flow regimes. The studies show that usage of helically coiled tube merely gives higher heat transfer rate and pressure drop in comparison to straight one, additionally, the heat transfer performance increases with the inclusion of the combination of other passive heat transfer enhancement methods to helically coiled tube. Moreover, the subject of single-phase flow in helically coiled tubes is ascertained to be worth researching due to the fact that there are limited number of studies and is still no empirical or analytical model/correlation in the case of using enhanced surfaces and wire coil insert. Forthcoming researches on this issue in the near future will be considered as pioneer ones in literature.

Published: February 2022

The purpose of this work was to perform a thermal–hydraulic numerical analysis of a nanofluid as the coolant in a typical MTR (material testing reactor) core. Numerical simulation was carried out for turbulent flow of water based nanofluid of different concentrations of Al2O3 nanoparticles through a sub-channel of a typical MTR core subjected to cosine shape heat flux at various values of Reynolds number using the Ansys-Fluent computer code. The optimum performance of the studied nanofluid as a coolant in MTR core was determined by the determination of the conditions under which the total entropy generation due to both heat transfer and fluid flow had a minimum value. The results showed that this condition was at Re = 4.8 × 104. The studied range of Reynolds number (Re) and particle concentration (ϕ) were 2.5 × 104 ≤ Re ≤ 5.6 × 104 and 0% ≤ ϕ ≤ 9% respectively. Results for local and average heat transfer and flow characteristics were presented. For the studied range of Reynolds number and particle concentration, four new correlations were developed. Two correlations relating Nusselt number and friction coefficient with the parameters Re and ϕ whereas the other two correlations were one relating Nusselt number with Reynolds and Prandtl numbers and the other relating the friction coefficient with Reynolds number.
Scattering asymmetry and circular dichroism in coupled PT-symmetric chiral nanoparticles
Authors: Chen Xiaolin , Wang Hongfei , Li Jensen , Wong Kwok-yin , Lei Dangyuan
Published: February 2022

We investigate the scattering properties of coupled parity-time (PT) symmetric chiral nanospheres with scattering matrix formalism. The exceptional points, i.e., spectral singularities at which the eigenvalues and eigenvectors simultaneously coalesce in the parameter space, of scattering matrix can be tailored by the chirality of the nanospheres. We also calculate the scattering, absorption and extinction cross sections of the PT-symmetric chiral scatter under illumination by monochromatic left- and right-circularly polarized plane waves. We find that the scattering cross section of the nanostructures exhibits an asymmetry when the plane waves are incident from the loss and gain regions, respectively, especially in the broken phase, and the optical cross section exhibits circular dichroism, i.e., differential extinction when the PT-symmetric scatter is endowed with chirality. In particular, under illumination by linearly polarized monochromatic plane waves without intrinsic chirality, the ellipticity of scattered fields in the forward direction, denoting the chirality of light, becomes larger when the scatter is in the PT-symmetry-broken phase. Our findings demonstrate that the gain and loss can control the optical chirality and enhance the chiroptical interactions and pave the way for studying the resonant chiral light–matter interactions in non-Hermitian photonics.
Worship or weight? A Bronze Age ‘goddess with a necklace’ from River Tollense (NE Germany)
Authors: Terberger Thomas , Borgwardt Ronald , Krüger Joachim , Lorenz Sebastian , Schmidt Jens-Peter , Rahmstorf Lorenz
Published: February 2022

The Tollense valley in northeast Germany is well known for its substantial evidence indicating a violent conflict dated to the early 13th century BC (Period III of the Nordic Bronze Age). This article presents a significant new find from a later Bronze Age context, found in the river at a known Bronze Age valley crossing (site Weltzin 13) by Ronald Borgwardt in 2020. The small bronze figurine (14.7 cm tall) has an egg-shaped head with a prominent nose, looped arms, a neckring, two knobs signifying breasts, a belt, an indication of a female sex and two slightly differently shaped legs. In the 19th century a similar female statuette was found near the village of Klein Zastrow, just a few kilometres from the valley crossing, but mostly these figurines are known from Zealand and Scania. Belts are only present on the statuettes from Zealand and northern Germany, and their presence suggests a close connection between the figures from these areas. Typological evidence places the figure from the Tollense river to the Late Bronze Age (Periods V–VI). Some time ago the figures were discussed as possible balance weights, but their small number does not support this theory. With a mass of 155 g, however, the new figure could be seen as a multiple of 26 g, the previously proposed weight unit of the time. The new find further suggests a connection between the find spots of the statuettes and routes of communication. There is little evidence to support an interpretation as a goddess. The deposition of the new figure at a valley crossing where hundreds of years before a violent conflict happened, might indicate that this was still a place of commemoration.
Agency, sentiment, and risk and uncertainty: fears of job loss in 8 European countries
Authors: Clark Gordon L.
Published: February 2022

How people assess their prospects and act accordingly is anchored in time and space. But context is only half the story. Human beings share predispositions in favour of the here and now, discounting the future, and risk aversion. This paper provides a framework for integrating cognition with context in economic geography focusing upon agency, resources, and risk and uncertainty in European labour markets. In doing so, it seeks to avoid essentialising the individual while ensuring that the resulting framework does not leave individuals as cyphers of time and place. The framework is illustrated by reference to individual’s assessments of the consequences of technological change for their employment prospects in a multicountry European setting. Implications are drawn for a behavioural economic geography that is policy relevant.
The Rhetoric of Matthean “Small Faith”
Authors: Seglenieks Christopher
Published: February 2022

Matthew uses ὀλιγόπιστος to critique inadequate faith from the disciples, adapting already linked Markan pericopes to create a set with a distinct rhetorical function. For the Gospel audience, these function together to call people to the sort of wholehearted trust exemplified in the first use of the term (6,25–34), while developing this ideal in a christological direction. Linguistic studies on the role of the vocative highlight how ὀλιγόπιστος is used to effect this goal, as it serves to recharacterize the disciples, drawing attention to the narrative frame, and emphasising the imperative force of Jesus’ rhetorical questions.
Adam’s Animal Farm: A Fresh Reading of the Anthropological-Hamartiological Framework of the Apocalypse of Moses
Authors: Koning Harro
Published: February 2022

A commonly recognized feature of the Apocalypse of Moses is its ethical-inferential orientation. However, the present article seeks to show that this does not just manifest itself in retrospective reflection, but is also exemplified narratologically in the attacks on Cain, Abel, and Seth. Far from being superfluous to the main narrative, these incidents provide us with a paradigm for understanding the Apocalypse’s anthropological-hamartiological framework in the post-paradisiacal world: The one who does what is good will send both devil and beast into flight, but the one who does not will be overcome by them. In order to substantiate this thesis, the article compares the Apocalypse to the works of Philo and the Testaments of the Twelve Patriarchs.

Integrated Amygdala, Orbitofrontal and Hippocampal Contributions to Reward and Loss Coding Revealed with Human Intracranial EEG
Authors: Manssuer Luis , Qiong Ding , Wei Liu , Yang Ruoqi , Zhang Chencheng , Zhao Yijie , Sun Bomin , Zhan Shikun , Voon Valerie
Published: February 2022

Neurophysiological work in primates and rodents have shown the amygdala plays a central role in reward processing through connectivity with the orbitofrontal cortex (OFC) and hippocampus. However, understanding the role of oscillations in each region and their connectivity in different stages of reward processing in humans has been hampered by limitations with noninvasive methods such as poor spatial and temporal resolution. To overcome these limitations, we recorded local field potentials (LFPs) directly from the amygdala, OFC and hippocampus simultaneously in human male and female epilepsy patients performing a monetary incentive delay (MID) task. This allowed us to dissociate electrophysiological activity and connectivity patterns related to the anticipation and receipt of rewards and losses in real time. Anticipation of reward increased high-frequency gamma (HFG; 60–250 Hz) activity in the hippocampus and theta band (4–8 Hz) synchronization between amygdala and OFC, suggesting roles in memory and motivation. During receipt, HFG in the amygdala was involved in outcome value coding, the OFC cue context-specific outcome value comparison and the hippocampus reward coding. Receipt of loss decreased amygdala-hippocampus theta and increased amygdala-OFC HFG amplitude coupling which coincided with subsequent adjustments in behavior. Increased HFG synchronization between the amygdala and hippocampus during reward receipt suggested encoding of reward information into memory for reinstatement during anticipation. These findings extend what is known about the primate brain to humans, showing key spectrotemporal coding and communication dynamics for reward and punishment related processes which could serve as more precise targets for neuromodulation to establish causality and potential therapeutic applications.

SIGNIFICANCE STATEMENTDysfunctional reward processing contributes to many psychiatric disorders. Neurophysiological work in primates has shown the amygdala, orbitofrontal cortex (OFC), and hippocampus play a synergistic role in reward processing. However, because of limitations with noninvasive imaging, it is unclear whether the same interactions occur in humans and what oscillatory mechanisms underpin them. We addressed this issue by recording local field potentials (LFPs) from all three regions in human epilepsy patients during monetary reward processing. There was increased amygdala-OFC high-frequency coupling when losing money which coincided with subsequent adjustments in behavior. In contrast, increased amygdala-hippocampus high-frequency phase-locking suggested a role in reward memory. The findings highlight amygdala networks for reward and punishment processes that could act as more precise neuromodulation targets to treat psychiatric disorders.

Published: February 2022

Objective

The association between insulin therapy and the risk of biliary tract cancer (BTC) is uncertain. We aimed to assess this risk in type 2 diabetic patients.

Methods

Using electronic medical data from the Shanghai Hospital Link database, 202,557 patients with type 2 diabetes (164,997 insulin never-users and 37,560 insulin ever-users) were identified in this study between January 1, 2013, and December 31, 2016, with follow-up until December 31, 2019. By propensity score matching, an ever-user was matched with a never-user. Cox proportional hazards regression analysis was used to estimate risk ratios (HRs) and 95% CIs for three subtypes of BTC (intrahepatic cholangiocarcinoma (ICC), extrahepatic cholangiocarcinoma (ECC), and gallbladder cancer (GBC)).

Results

At a mean follow-up of 5.33 years, 143 cases of BTC were observed. The crude incidence rates (per 100,000 person-years) of ECC, ICC, and GBC in ever-users:never-users were 10.22:3.63, 2.04:2.04, and 8.17:6.01, respectively. Insulin therapy was associated with an increased risk of ECC (HR, 4.10; 95% CI, 1.54–10.92; P  = 0.005) compared to patients who never used insulin. No statistically significant results were observed for insulin and ICC/GBC. Consistent results were also found in the original cohort.

Conclusions

The relationship between insulin therapy and BTC is type-specific. Further studies are warranted to provide evidence on the identification of ECC risk groups among type 2 diabetic patients.

Published: February 2022

Objective

This study aimed to evaluate the association between the endocrine-disrupting chemical, bisphenol A (BPA) on circulating levels of 25-hydroxy vitamin D (25(OD)D) and other vitamin D metabolites in an elderly population in Italy.

Methods

This was a retrospective analysis of the InCHIANTI Biobank in Italy. The association between vitamin D metabolites namely 1,25(OH)D, 25(OH)D, parathyroid hormone (PTH) and BPA levels were evaluated. Multiple regression models were used to examine the association between predictor variables with 1,25(OH)D or 25(OH)D levels.

Results

Samples from 299 individuals aged 72.8 ± 15.7 years were examined. Mean levels of BPA, 1,25(OH)D and 25(OH)D were 351.2 ± 511.6 ng/dL, 43.7 ± 16.9 pg/mL and 20.2 ± 12.1 ng/mL, respectively. One hundred eighty individuals (60.2%) were deficient (<20 ng/mL) in 25(OH)D and this population also presented higher BPA levels (527.9 ± 1289.5 ng/dL vs 86.9 ± 116.8 ng/dL, P  < 0.0001). Univariate analysis revealed that BPA levels were negatively correlated with both 1,25(OH)D (r= −0.67, P  < 0.0001) and 25(OH)D (r= −0.69, P  < 0.0001). Multivariate regression revealed that PTH (β: −0.23, 95% CI: −0.34, −0.13, P  < 0.0001) and BPA (β: −0.25, 95% CI: −0.3, −0.19, P  < 0.0001) remained significantly associated with 25(OH)D levels while BPA was also associated with 1,25(OH)D levels (β: −0.19, 95% CI: −0.22, −0.15, P  < 0.0001). Receiver operating characteristic curve analysis showed that a BPA concentration of >113 ng/dL was the best cut-off to predict individuals deficient in 25(OH)D (area under the curve: 0.87, 95% CI: 0.82–0.90, P  < 0.0001).

Conclusion

The strong negative association between BPA and vitamin D in this elderly population warrants further investigation, particularly since this population is already at greatest risk of hypovitaminosis and fracture.

Published: February 2022

Objective

Asprosin is a recently discovered hormone associated with obesity and diabetes mellitus. Little is known about asprosin’s role during pregnancy, but a contribution of asprosin to pregnancy complications resulting from maternal obesity and gestational diabetes mellitus (GDM) is conceivable. We assessed the potential effects of obesity, GDM and other clinical parameters on maternal and fetal umbilical plasma asprosin concentrations and placental asprosin expression.

Design

The Cologne-Placenta Cohort Study comprises 247 female patients, from whom blood and placentas were collected at the University Hospital Cologne.

Methods

We studied the maternal and fetal umbilical plasma and placentas of pregnant women with an elective, primary section. Sandwich ELISA measurements of maternal and fetal umbilical plasma and immunohistochemical stainings of placental tissue were performed to determine the asprosin levels. Also, the relation between asprosin levels and clinical blood parameters was studied.

Results

There was a strong correlation between the maternal and fetal plasma asprosin levels and both increased with GDM in normal-weight and obese women. Asprosin immunoreactivity was measured in cultivated placental cells and placental tissue. BMI and GDM were not but pre-pregnancy exercise and smoking were correlated with maternal and/or fetal asprosin levels. Placental asprosin levels were associated with maternal but not with fetal plasma asprosin levels and with BMI but not with GDM. Placental asprosin was related to maternal insulin levels and increased upon insulin treatment in GDM patients.

Conclusions

Asprosin could potentially act as a biomarker and contribute to the clinical manifestation of pregnancy complications associated with maternal obesity.

inhibiting interstitial and extracellular collagenase, thus having the potential to reduce the progression of periodontitis. Here we compare and evaluate the aerobic and anaerobic microorganism’s CFUs (colony forming units) in plaque samples of Group A, Group B, Group C and severity of periodontal disease on day 0 and 7.
Method. Forty-five subjects in age range 18-30 years were selected among undergraduate students and randomly divided into Group A: 15, 2% grape seed extract mouthwash (GSE), Group B: 15, 0.2% chlorhexidine mouthwash (CHX) and Group C: 15, distilled water (control). The supragingival plaque was collected into transport media. Kruskal Wallis test followed by Mann Whitney test was used to compare the mean CFUs [x103] of microorganisms and severity of periodontal disease was compared, by clinical parameters among all groups on day 0 and 7.
Results. There was a significant difference concerning mean scores of all clinical parameters [P<0.001] and mean CFUs of microorganisms between 3 study groups [P=0.005] at 7 days post-intervention period. Intragroup comparison, mean scores were significantly reduced on day 7 as compared to day 0 at [P<0.001] in Group A and B, but no significant difference was noted with Group C. 
Conclusion. Intervention with GSE mouthwash showed a positive effect on reducing CFUs in the plaque when compared with the control group. GSE group also showed similar results in reducing CFUs in plaque when compared to CHX group, thereby demonstrating the agent’s antimicrobial efficacy, therapeutic effect and its potential usefulness in controlling plaque and periodontal diseases.

The relationship between periodontitis (or periodontal disease) with Alzheimer’s disease has been reported by various primary sources in the past decade, but not with a solid secondary research statement. A systematic review and meta-analysis was conducted in accordance with the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement and registered (Reference number: CRD42020185264) with PROSPERO (International prospective register for systematic reviews). A literature search was conducted on specific databases for suitable articles in English language. Out of 612 studies selected, 41 underwent full-text analysis; five studies were eligible for systematic review, and 3 for meta-analysis. Meta-analysis was performed with tests for sensitivity and statistical heterogeneity followed by calculation of summary effect measures in terms of odds ratio (OR) and 95% confidence interval (CI). The results of this review showed a significant association between periodontitis and Alzheimer’s disease in the meta-analysis [OR 1.67 (1.21–2.32)].

The effects of waste loading in vitrified high-level nuclear waste (HLW) from the reprocessing of high-burnup spent fuel (56 GWd/tHM) on waste volume reduction (i.e., number of HLW canisters produced) and decay heat generation were investigated to minimize the repository footprint. As the waste loading increases, the number of canisters produced decreases; however, the decay heat and subsequent footprint per canister increase. The best estimate waste loading observed was 23 wt% (including 10 wt% Na2O), wherein the repository footprint minimizes to 60.0 m2/tHM. These results are slightly higher than those for standard HLW (55.5 m2/tHM). However, upon comparing the repository footprint with electric power generation, the benefit of optimization was that the footprint for high-burnup HLW (131 m2/TWh) was 13% smaller than that of standard HLW (151 m2/TWh).

El modelo del amo en Cumbres Borrascosas de Emily Brontë: una lectura ecofeminista
Authors:   Universidad de Granada, Romero-Pérez María Isabel
Published: February 2022

Cumbres Borrascosas (1847) de Emily Brontë, una de las obras canónicas de la literatura inglesa, ilustra la distorsión y la polarización de la naturaleza, la resistencia a las figuras patriarcales y la importancia primordial del saber y la razón en la disolución y el reclamo de identidades marginadas. Aproximándonos a la narrativa mediante la crítica (eco)feminista de Plumwood (1993/2003), este artículo tiene como objetivo analizar la dimensión política de las relaciones humanas con la naturaleza y las formas dominantes de racionalidad en la estructura lógica de dualismos. Esta lente ha permitido una lectura ecofeminista de las opresiones interrelacionadas de raza, clase y género en la construcción de Catherine y Heathcliff. La posición fluctuante de estos protagonistas en la escala de alteridad revela la dinámica de poder de los centros hegemónicos en ambas familias, en Cumbres Borrascosas y en la Granja de los Tordos. En este contexto, la educación finalmente apunta a una posible reconciliación de los binarismos opuestos del modelo del amo en la segunda generación de personajes, Cathy y Hareton. Los personajes de Emily Brontë enfatizarán la compleja articulación de las fuentes de tensión y los mecanismos de opresión en funcionamiento en Cumbres Borrascosas

South Africa’s National Senior Certificate examination system was introduced in 2008 as a single national examination system, in order to facilitate fair and standardised assessment and to provide all learners with an equal chance of access to higher education. However, limited research has been done to investigate the discrimination power of the actual examination items and the spread difficulty level for learners from different school quintile types. The purpose of the study reported on here was to investigate differential performance of learners in the items of the 2009 National Senior Certificate mathematics examination. The dataset used in this study was from the Western Cape (WC) Education Department. From the analysis, the results show that the discrimination power of the different examination questions was not identical across different school quintiles. Further investigation of the data reflects a considerable range of category difficulty levels, with higher (above average) ability levels being tested for learners in the quintile 1 to quintile 4 schools, while only learners with average abilities were being tested in the quintile 5 and independent schools.

In this article we report on a qualitative study done in Pretoria, South Africa, in which we investigated the experiences of 2 representatives of the Gauteng Department of Education (GDE); School Governing Body (SGB) spokespersons from 4 schools located in the Gauteng province, 2 representatives of the Federation of SGBs, 4 principals from 4 schools, and 4 parents from 4 schools regarding public primary schools’ admission policies and practices as enablers or disablers of children’s rights to basic education. Using structured, open-ended interviews, qualitative data were generated to explore the experiences of the participants on the public primary schools’ admission policies and practices as enablers or disablers of a right to basic education. We argue that the implementation of school admission policies as enabler to access to basic education must be based on a system of rights and corresponding obligations established by the Constitution of the Republic of South Africa, 1996, and the various legislative and policy frameworks. The findings of the study reveal that the learner admission system in South African public schools remains problematic, which in turn aids as a disabler of children’s right to basic education.
Modelo teórico para levantamento e organização de subsunçores no âmbito da Aprendizagem Significativa
Authors: Silva Filho Olavo Leopoldino da , Ferreira Marcello
Published: February 2022

The Meaningful Learning Theory presents two absolutely crucial steps to reach the goal of meaningful teaching. The survey of subsumers, followed by their advanced organization, are conditions of possibility for learning to break the barrier of a merely mechanical learning, aimed at ephemeral memorization. However, such steps are very often disregarded, even by those who explicitly assume this theoretical framework. The survey stage of subsumers, in particular, is riddled with subjectivities on the part of those who organize learning, which brings the extra difficulty of being able to establish comparisons between surveys of subsumers by different teachers. The advanced organization stage, in turn, suggests a personalized teaching approach, since students’ cognitive structures can differ, and usually do, widely. This work seeks to present a methodology that tackles both problems. Without neglecting the inherent subjectivity of the survey of subsumers, it presents a formalization of it, through the fuzzy inference technique, also presenting its computational implementation. The issue of personalization of teaching based on this methodology is also addressed.
Do Isolamento à Cogestão: A Gestão Autônoma da Medicação (GAM) com Familiares
Authors: Renault Letícia , Passos Eduardo
Published: February 2022

Resumo Este artigo apresenta a experiência de pesquisa-intervenção participativa da Gestão Autônoma da Medicação (GAM) com familiares. A GAM, de origem canadense, procura discutir criticamente o uso da medicação psiquiátrica de modo a fomentar a autonomia dos usuários desses medicamentos. No Brasil, o chamado projeto GAM-BR realizou a tradução, adaptação e validação do instrumento utilizado nesta abordagem, o Guia GAM. Seguimos as indicações teórico-práticas da abordagem enativa e empregamos a metodologia da cartografia, em especial a técnica da entrevista cartográfica. Como um projeto participativo, a validação do Guia contou com usuários e trabalhadores dos serviços de saúde mental brasileiros (Caps) como copesquisadores. A realização de um grupo com familiares de usuários na etapa de validação do Guia foi uma inovação na GAM-BR que possibilitou a inclusão desse grupo fundamental para a discussão acerca do tratamento medicamentoso. Podemos destacar dois efeitos processuais desse trabalho com familiares: a promoção de deslocamentos de ponto de vista e a promoção de corresponsabilização. Tais efeitos sugerem perspectivas para a GAM e para o trabalho em saúde mental, em um horizonte de inclusão e composição entre diferentes perspectivas.
Mulheres em Situação de Rua: Implicações Psicossociais de Estigmas e Preconceitos
Authors: Esmeraldo Andréa Ferreira Lima , Ximenes Verônica Morais
Published: February 2022

Resumo É cada vez maior o número de pessoas vivendo nas ruas, contudo, ainda são reduzidos os estudos e as políticas públicas voltados ao público feminino, razão pela qual este artigo focalizou o cotidiano das ruas objetivando analisar as implicações psicossociais dos estigmas e preconceitos na vida das mulheres em situação de rua. Ser mulher nesse cenário evoca relações de poder inseridas no conceito de gênero, considerado enquanto construção social e calcado em relações patriarcais. Estar nas ruas é estar exposta e ser alvo de ações discriminatórias que passam pela invisibilidade perante as políticas públicas, por processos de exclusão e por ações violentas perpetradas na rede de relações tecidas a partir da rua. Realizamos uma pesquisa qualitativa, na qual utilizamos entrevistas em profundidade com sete mulheres em situação de rua na cidade de Maracanaú (CE). O material coletado foi submetido à Análise de Conteúdo, que contou com apoio do software Atlas Ti 5.2 para identificar processos opressivos presentes nos estigmas e nos preconceitos, que atuam por meio de desqualificação e descrédito dessas mulheres e conduzem a sentimentos de humilhação e vergonha capazes de incidir sobre seus modos de vida e sobre as relações estabelecidas em seu cotidiano.

Resumo Estima-se que um a cada cinco estudantes universitários ao redor do mundo apresenta algum tipo de transtorno psicológico, dentre os quais os transtornos de ansiedade são os mais prevalentes. Este estudo consiste em um ensaio clínico randomizado com o objetivo de avaliar a eficácia e efetividade de um protocolo semiestruturado de psicoterapia em grupo baseado nos princípios da Terapia de Aceitação e Compromisso (ACT) para o tratamento de ansiedade entre estudantes universitários. Os participantes foram alocados aleatoriamente entre os grupos intervenção e controle. Os níveis de ansiedade pré e pós-intervenção foram avaliados por meio do instrumento General Anxiety Disorders-7 (GAD-7). A amostra final do estudo foi composta por 15 pessoas, dentre as quais 10 foram alocadas no grupo intervenção e 5, no grupo controle. Os resultados foram analisados de duas formas: a) por protocolo (Per-protocol analysis); e b) por intenção de tratar (Intention-to-treat Analysis). Este tratamento reduziu a sintomatologia ansiosa em 39,7% entre os pacientes que completaram o tratamento (por protocolo, p=0,030) e em 30,8% entre todos alocados para o grupo intervenção (i.e., por intenção de tratar, incluindo os dropouts, p=0,035), enquanto os controles não tiveram redução significativa no mesmo período. Portanto, recomenda-se a utilização deste protocolo dentro do contexto universitário como uma alternativa viável ao acompanhamento individual em situações de transtornos de ansiedade. Pesquisas futuras com amostras maiores podem contribuir na consolidação deste protocolo.

ABSTRACT The objective of this study was to evaluate the biochemical parameters of goats submitted to castration or not and receiving supplementation with vitamin E or not. A total of 24 goats, uncastrated (12 experimental units) and castrated males (12 experimental units), with average body weight weighing 17.6 kg ± 2.67 kg, were distributed in a completely randomized design in a 2 x 2 factorial arrangement, with two animal conditions (castrated and uncastrated male) and vitamin E supplementation (with and without supplementation), with six replications. There was an effect of treatments (P<0.05) over time for all studied variables. There was an effect of vitamin supplementation (P<0.05) for phosphorus, iron, protein, glucose, aspartate aminotransferase (AST), alanine aminotransferase (ALP) and gamma-glutamyltransferase (GGT). Vitamin supplementation increased glucose, creatinine and GTT levels over time, and reduced levels of phosphorus, iron, protein, albumin, AST and ALP. We conclude that vitamin E influenced the biochemical parameters studied, but castration did not change the biochemical profile of goats, regardless of whether they were supplemented with vitamin E or not.
