Authors: Baburao Archana , Maurya Poonam , Chakenahalli Amulya , Narayanswamy Huliraj 
Published: November 2021

Desmoplastic small round cell tumor (DSRCT) is a rare, extremely aggressive and malignant tumor predominantly affects young adolescent males and typically presents as a large intra-abdominal mass. However, tumor arising from other body sites are also reported in the literature. Histology and immunohistochemistry play an important role in the diagnosis and differentiating this rare tumor from other round cell tumors. A multidisciplinary approach consisting of a combination of surgery, chemotherapy and radiation therapy is the treatment of choice as there is no standard therapy. We report a case of DSRCT of pleura presenting as bilateral pleural effusion in a young adolescent male who was treated with both surgery and chemotherapy. However patient succumbed to death after one year of diagnosis.

Published: November 2021

Purpose: To investigate the effect of Klotho and FOXO1/3 on the CH viability in OA.Methods: The survival rate of CHs, Klotho and FOXO1/3 protein expression, and ROS production were measured in the OA cartilages of different degenerative phases. H2O2 was also used to injure CHs, and the cell viability, Klotho and FOXO1/3 expressions, as well as ROS levels were investigated to clarify the effect of exogenic Klotho on the injured CHs. Additionally, in order to verify the role of FOXO1/3 in Klotho-treated CHs, SOD2, GPX1, inflammatory factors, collagen I/II, SOX9, and Runx-2 levels were analyzed by silencing FOXO1 and FOXO3 expression via siRNA transfection.Results: Klotho and FOXO1/3 expressions significantly decreased, and ROS production increased in severely human OA cartilage (p <0.05). Besides, H2O2 affected CHs viability with the suppression of Klotho and FOXO1/3 expression but ROS production was elevated. Exogenic Klotho application partly reversed the injury caused by H2O2. Furthermore, Klotho treatment of the injured CHs contributed to SOD2 and GPX1 expressions, and suppressed IL-1β, IL-6, TNF-α and MMP-13 production, resulting in the upregulation of collagen II and SOX9 as well as downregulation of collagen I and Runx-2. However, the protective effect of Klotho was weakened by FOXO1 and FOXO3 gene silencing.Conclusion: Klotho protects CHs viability by suppressing oxidative stress and inflammation, which is associated with the mediation of FOXO1 and FOXO3. These findings provide new insights into the treatment of OA.

The key role of GNSS for monitoring geodetic parameters of the Earth
Authors: Кузин С.П. 
Published: November 2021

Глобальные навигационные спутниковые системы (ГНСС) являются основным инструментом для контроля геодезических параметров Земли, построения и постоянного контроля земной системы отсчета и связи измерений различных спутниковых геодезических технологий. ГНСС состоят из наземного сегмента (приемники ГНСС) и орбитальной группировки (навигационные спутники системы). Микроволновый диапазон сигналов ГНСС позволяет использовать данные системы при любых погодных условиях, а двухчастотные несущие позволяют, в значительной степени, исключить ионосферную задержку распространения сигналов. Помимо выполнения основных геодезических определений навигационные системы также могут быть использованы для решения социальных и других позиционных измерений, требующих высокой точности. В данной статье автором рассмотрены основные задачи, решаемые ГНСС, определены требования к точности продуктов навигационных систем и приведены направления развития наземной и орбитальных частей ГНСС, учитывая потребности мирового геодезического сообщества.
Global navigation satellite systems (GNSS) are a fundamental tool for monitoring geodesic parameters of the Earth, building and constantly monitoring the Earth’s reference system and connecting measurements of various satellite geodetic technologies. GNSS consist of a ground segment (GNSS receivers) and an orbital grouping (navigation satellites of the system). The microwave range of GNSS signals allows using these systems in all weather conditions, and the two-frequency carriers allow, to a large extent, eliminating the ionospheric delay of signal propagation. In addition to performing basic geodetic definitions, GNSS can also be used to solve social and other positional measurements that require high accuracy. In this article the author discusses the main tasks solved by GNSS, defines the requirements for the accuracy of navigation systems products, and provides directions for the development of the ground and orbital parts of GNSS taking into account the needs of the international geodetic community.

Triple-frequency radar retrieval of microphysical properties of snow
Authors: Mroz Kamil , Battaglia Alessandro , Nguyen Cuong , Heymsfield Andrew , Protat Alain , Wolde Mengistu 
Published: November 2021

Abstract. An algorithm based on triple-frequency (X, Ka, W) radar measurements that retrieves the size, water content and degree of riming of ice clouds is
presented. This study exploits the potential of multi-frequency radar measurements to provide information on bulk snow density that should underpin
better estimates of the snow characteristic size and content within the radar volume. The algorithm is based on Bayes' rule with riming
parameterised by the “fill-in” model. The radar reflectivities are simulated with a range of scattering models corresponding to realistic
snowflake shapes. The algorithm is tested on multi-frequency radar data collected during the ESA-funded Radar Snow Experiment For Future Precipitation Mission. During this campaign,
in situ microphysical probes were mounted on the same aeroplane as the radars. This nearly perfectly co-located dataset of the remote and in situ
measurements gives an opportunity to derive a combined multi-instrument estimate of snow microphysical properties that is used for a rigorous
validation of the radar retrieval. Results suggest that the triple-frequency retrieval performs well in estimating ice water content (IWC) and
mean mass-weighted diameters obtaining root-mean-square errors of 0.13 and 0.15, respectively, for log 10IWC and
log 10Dm. The retrieval of the degree of riming is more challenging, and only the algorithm that uses Doppler information obtains
results that are highly correlated with the in situ data.
ALMAN VE İSVİÇRE HUKUKU İLE KARŞILAŞTIRMALI OLARAK TÜRK HUKUKUNDA BAŞLANGIÇ KİRA BEDELİNİN SINIRLANDIRILMASI MESELESİ
Authors: INCE Nurten , ÖZYAKIŞIR Özkan 
Published: November 2021

Bazı ülkelerin hukuki düzenlemelerinde, kiracının korunması esası benimsenip kiracıyı koruyucu özel hükümler ihdas edilmiştir. Söz konusu ülkelerde, genellikle kira bedelinin serbestçe belirlenmesinin ve/veya artırılmasının önüne geçilerek kiracının korunması amaçlanır. Misal, Alman ve İsviçre hukukunda, özel düzenlemeler uyarınca taraflar, yeni bir kira sözleşmesi akdederken dahi kira bedelini serbestçe belirleyememektedirler. Bir başka deyişle, bahsi geçen ülkelerde, başlangıç kira bedeli özel hükümler yoluyla sınırlandırılmıştır. Türk hukukunda ise 6098 sayılı TBK m. 344’te kira sözleşmesi devam ederken kira bedelinde meydana gelecek artış sınırlandırılmış, ancak başlangıç kira bedelini sınırlayan özel bir hüküm öngörülmemiştir. Oysa ki son zamanlarda Türkiye’de bazı illerde başlangıç kira bedellerinde büyük artışların yaşandığı görülmektedir.
Bu çalışmamızda, Alman ve İsviçre hukukundaki başlangıç kira bedeline ilişkin sınırlamalar ele alınıp Türk hukukunda Alman ve İsviçre hukukunda olduğu gibi başlangıç kira bedeline ilişkin sınırlamalara ihtiyaç duyulup duyulmadığı incelenecektir.
Humour and belonging: Insights from two summer scholars
Authors: Morrell Sofia , Oden Bryer 
Published: November 2021

How does humour in YouTube comments signal national belonging?Whenever we interact we offer signals of who we are and where we belong. In negotiating our identities with others, humour is an important part of the linguistic toolkit. To explore how we both explicitly and implicitly signal identity through language choices, Sofia offers an analysis of comments from viewers of YouTube vlogs, noting in particular the ways in which we claim the status of ‘New Zealander’ through our use of and responses to humour. The goal is to consider national community alignment and the embedding of identity categories within this asynchronous, written context.How to develop an integrated-writing test?Using data from Victoria University of Wellington’s Language in the Workplace project, specifically data involving incomers to New Zealand and outbound New Zealanders, Bryer addresses the ways in which pragmatic understanding is central to the navigation and maintenance of successful workplace relationships. A series of transcribed interactions will demonstrate the use of humour as power, alongside reflections on experience with humour at work. By doing so, Bryer outlines how humour can be a powerful tool to uphold the hegemony of workplace power relations.
Desconsideração da personalidade jurídica e novo contexto jurídico social do negócio jurídico
Authors: Tourounoglou Felipe Teles 
Published: November 2021

Considerada uma realidade autônoma a pessoa jurídica é dotada de direitos e obrigações as quais independem de seus componentes, não tendo nenhum vínculo, agindo por si só, sem qualquer ligação com a vontade individual das pessoas físicas que compõem o grupo. Reconhecida pela legislação vigente como um importante instrumento para o exercício da atividade empresarial, a personalidade jurídica deve ser usada com propósitos legítimos, de forma que a finalidade para qual foi criada seja atendida, no entanto quando esses propósitos são desvirtuados, por meio de abuso da personalidade jurídica, caracterizado pelo desvio de finalidade ou pela confusão patrimonial, a personalidade jurídica poderá ser afastada, de modo que não ocorrerá a separação patrimonial entre a pessoa jurídica e seus membros, desta forma o bens particulares dos sócios perderão a intangibilidade, ou seja ocorrerá o descarte da autonomia patrimonial, não havendo mais a separação entre sociedade e sócio, estendendo a responsabilidade a estes, com alcance dos bens patrimoniais pessoais. A presente pesquisa objetiva analisar o instituto da desconsideração da personalidade jurídica no cotejo mudanças do novo contexto jurídico social do negócio jurídico

Can older workers be retrained? Canadian evidence from worker-firm linked data
Authors: Fang Tony , Gunderson Morley , Lee Byron 
Published: November 2021

Our empirical analysis is based on Statistics Canada’s worker-firm matched data set, the 2003 Workplace and Employee Survey (WES). The sample size is substantial: about 4,000 workers over the age of 50 and 12,000 between the ages of 25 and 49. Training was a focus of the survey, which offers a wealth of worker-related and firm-related training variables.
We found that the mean probability of receiving training was 9.3 percentage points higher for younger workers than for older ones. Almost half of the gap is explained by older workers having fewer training-associated characteristics (personal, employment, workplace, human resource practices and occupation/industry/region), and slightly more than half by them having a lower propensity to receive training, this being the gap that remained after we controlled for differences in training-associated characteristics. Their lower propensity to receive training likely reflects the higher opportunity cost of lost wages during the time spent in training, possible higher psychological costs and lower expected benefits due to their shorter remaining work-life and lower productivity gains from training, as discussed in the literature.
The lower propensity of older workers to receive training tended to prevail across 54 different training measures, with notable exceptions discussed in detail. We found that older workers can be trained, but their training should be redesigned in several ways: by making instruction slower and self-paced; by assigning hands-on practical exercises; by providing modular training components to be taken in stages; by familiarizing the trainees with new equipment; and by minimizing required reading and amount of material covered. The concept of “one-size-fits- all” does not apply to the design and implementation of training programs for older workers.
Personnels navigants : un collectif de travail à l’épreuve du changement
Authors: Nogues Sarah , Tremblay Diane-Gabrielle , Mansour Sari 
Published: November 2021

Notre article porte sur les intensités et la fragilisation des collectifs de travail et offre une synthèse de la littérature concernant le travail et ses intensités, en particulier dans le milieu aérien. Prenant le cas du personnel navigant commercial (PNC) dans le milieu aérien, nous nous appuyons sur la théorie des demandes-ressources du travail et de l’organisation capacitante pour analyser les perceptions de ces travailleurs concernant les demandes physiques, psychosociales et organisationnelles du travail, ainsi que les ressources de même type, notamment à la suite de l’autorisation d’une réduction d’effectif par le ministère des Transports sur bon nombre de porteurs canadiens en juillet 2015. Nous portons une attention particulière aux demandes du travail constituant une contrainte, ce qui est rarement pris en compte dans les études sur l’intensification du travail. À l’aide du construit de caravanes de ressources et d’organisation capacitante, nous nous demandons si les collectifs de travail PNC sont en mesure d’accomplir leur mission collective de maintien de la sécurité et de service auprès du public. Nous avons pour cela mené 41 entrevues semi-dirigées auprès d’agents de bord et de directeurs de vol volontaires provenant de deux compagnies aériennes canadiennes. Nous avons procédé à une analyse de contenu qualitative faisant émerger les thèmes principaux de manière inductive et analysant les demandes et les ressources physiques, psychosociales et organisationnelles du travail. Nos résultats documentent de façon originale comment une augmentation notable des intensités contraignantes du travail perturbe les collectifs de travail, en particulier le rôle pivot du directeur de vol, contribuant à la recherche émergente au sujet de la fragilisation des processus de travail. De nombreux aspects demeurent à améliorer pour qualifier les compagnies aériennes étudiées d’organisations capacitantes.

Précis

De plus en plus complexes, les organisations modernes sont le lieu de diverses sources d’intensité pour les travailleurs, requérant de ces derniers des efforts selon des logiques et des injonctions plurielles, parfois contradictoires. Dans le milieu aérien, les compagnies recourent à divers modes de gestion impliquant beaucoup de changements rapides pour les employés, exigeant de ceux-ci une flexibilité et une adaptabilité croissantes. Cela dit, toutes les intensités du travail ne mènent pas nécessairement à la perception d’intensification du travail chez les employés. Nous nous intéressons au cas du personnel navigant commercial, un collectif faisant face à de nombreuses intensités du travail. Les agents de bord et les directeurs de vol canadiens ont-ils les moyens d’assurer leur mission collective de sécurité et de service auprès du public ?
O exame de admissão ao ensino superior como indicador de qualidade entre os estudantes
Authors: Collinson Ivan , Barbosa Adérito Gomes , Ribáuè Albertina 
Published: November 2021

O uso de avaliações, testes e exames remonta a vários séculos antes da nossa era, sendo um mecanismo ou instrumento com diversas aplicações, quer no contexto educacional, quer no contexto mais amplo da vida em sociedade. Especificamente, no que se refere ao ensino superior, a importância atribuída aos exames, em especial de admissão ao ensino superior, é enquadrada no contexto das funções desempenhadas pelos exames, de forma geral, mas em particular, pela percepção de qualidade que daí advém. A literatura disponível e consultada para o efeito, bem como os resultados de um inquérito realizado a uma amostra de estudantes do ensino superior, em específico da Universidade Eduardo Mondlane, em Moçambique, ilustra que os estudantes têm uma percepção de qualidade do ensino superior, resultante do mecanismo de ingresso usado, neste caso o exame de admissão à que foram sujeitos. Com efeito, conclue-se também que a validade do instrumento, proveniente da concepção correcta dos exames, é um indicador de qualidade do futuro graduado.
No evidence of effects or interaction between the widely used herbicide, glyphosate, and a common parasite in bumble bees
Authors: Straw Edward A. , Brown Mark J.F. 
Published: November 2021

BackgroundGlyphosate is the world’s most used pesticide and it is used without the mitigation measures that could reduce the exposure of pollinators to it. However, studies are starting to suggest negative impacts of this pesticide on bees, an essential group of pollinators. Accordingly, whether glyphosate, alone or alongside other stressors, is detrimental to bee health is a vital question. Bees are suffering declines across the globe, and pesticides, including glyphosate, have been suggested as being factors in these declines.MethodsHere we test, across a range of experimental paradigms, whether glyphosate impacts a wild bumble bee species,Bombus terrestris. In addition, we build upon existing work with honey bees testing glyphosate-parasite interactions by conducting fully crossed experiments with glyphosate and a common bumble bee trypanosome gut parasite,Crithidia bombi. We utilised regulatory acute toxicity testing protocols, modified to allow for exposure to multiple stressors. These protocols are expanded upon to test for effects on long term survival (20 days). Microcolony testing, using unmated workers, was employed to measure the impacts of either stressor on a proxy of reproductive success. This microcolony testing was conducted with both acute and chronic exposure to cover a range of exposure scenarios.ResultsWe found no effects of acute or chronic exposure to glyphosate, over a range of timespans post-exposure, on mortality or a range of sublethal metrics. We also found no interaction between glyphosate andCrithidia bombiin any metric, although there was conflicting evidence of increased parasite intensity after an acute exposure to glyphosate. In contrast to published literature, we found no direct impacts of this parasite on bee health. Our testing focussed on mortality and worker reproduction, so impacts of either or both of these stressors on other sublethal metrics could still exist.ConclusionsOur results expand the current knowledge on glyphosate by testing a previously untested species,Bombus terrestris, using acute exposure, and by incorporating a parasite never before tested alongside glyphosate. In conclusion our results find that glyphosate, as an active ingredient, is unlikely to be harmful to bumble bees either alone, or alongsideCrithidia bombi.
