Published: March 2022

In this paper, we present the effect of Cobalt (Co) addition on the crystallization, microstructures and magnetic properties of Mn55-xCoxBi45 (x = 0, 5, 10, 20) melt – spun ribbons. The ribbons were prepared by the melt-spinning techique and subsequent anneal at 280 oC for 5 h. The investigations by using X-ray diffraction (XRD), Differential Scanning Calorimetry (DSC) traces as well the Vibration Sample Magnetometer (VSM) measurements result in the optimal content of Co added to the MnBi system is arounf 5 %at. The larger Co content causes the eutectic Mn-Co formation which restricts the reaction between Mn and Bi to form MnBi ferromagnetic phase responsible for ribbons’ performance the saturation magnetization Ms. The maximum saturation magnetization Ms of 65emu/g and the coercivity iHc of 4.7 kOe was achived for the ribbon of Mn50Co5Bi45. The effect of Co content on the microstructures and magnetic properties of Mn55-xCoxBi45 melt – spun ribbons will be discussed in detail.

Powdery mildew and downy mildew are primary fungal diseases that cause significant damage in viticulture. Therefore, breeding powdery and/or downy mildew resistance is one of the priority subjects in grapevine breeding programs. This study aims to conduct early-selection by marker assisted selection (MAS) method among 869 genotypes obtained through crossbreeding ‘Alphonse Lavallee’ × ‘Regent’ cultivars using the markers (GF18-06 and GF18-08) associated with downy mildew resistance gene region Rpv3.1 to develop new grapevine cultivars resistant to downy mildew caused by Plasmopara viticola. A total of 869 hybrid plants which were obtained after crossing ‘Alphonse Lavallee’ × ‘Regent’ in a 3-year breeding program were used in the study. The hybrid plants were scored for the resistance level based on their sporulation intensity after artificial inoculation of P. viticola. DNA samples of the hybrid plants were amplified with GF18-06 and GF18-08 markers in Polymerase Chain Reaction (PCR) for MAS. The alleles which were associated to Rpv3.1 resistance locus and the results of resistance scoring were compared, and the applicability of the markers in MAS was verified. It was determined that the GF18-08/410 bp marker can be used successfully for MAS. Gf 18-06 marker 385 bp, 390 bp and 407 bp gave false positive results in our population, respectively 8.86%, 9.02% and 37.94%. Therefore, this may limit its use for MAS.

COVID-19 KÜRESEL SALGIN DÖNEMİNDE ÜCRETİN KORUNMASI
Authors: ESER Dilek 
Published: March 2022

Ücret, işçinin ve ailesinin yegâne geçim kaynağıdır. Aynı zamanda, devletler için önemli bir refah göstergesi ve vergi kalemidir. Bu nedenle işçiyi, ailesini ve ekonomik anlamını korumak için ücretin mevzuat bakımından güvenceye alınması bir zorunluluktur. Bu zamana kadar gerek uluslararası anlaşmalarda gerekse ulusal mevzuatlarda ücretin korunması ile ilgili sınırlar, ayrıcalıklar ve kapsam belirlenmiştir. Ancak; 2019 yılının sonunda Çin’de başlayan, hızla dünyaya yayılan COVID-19 kısa süre sonra Dünya Sağlık Örgütü’nce küresel salgın ilan edilmesine neden olmuş ve yaşanan sosyal ve ekonomik krizler ücretin korunması ile ilgili düzenlemeleri yetersiz kılmış, konuyu yeniden gündeme getirmiştir. Bu dönemde, işletmeler kapatılmış, tedarik zincirleri aksamış, ulaşım kısıtlanmış, işsizlik ve eksik istihdam artmıştır. Özellikle ücretli toplumlarda, yaşanan bu ekonomik kriz sosyal krizlere dönüşmüştür. Bu süreçte, iş hukuku uygulamaları sorgulanır hale gelmiştir. Böylece tüm dünyada iş hukuku düzenlemeleri yeniden gözden geçirilmiş, kapsam ve hak etme koşullarında basitleştirmelere gidilmiştir. Ayrıca yeni uygulamalarla mevzuat bağlamında koruma kapsamına girmeyen işçiler de görece güvenceye alınmıştır.
Türkiye’de sürecin nasıl yönetildiği ve özellikle ücretin korunması bağlamındaki değişiklik ve düzenlemeleri incelemek, bu çalışmanın temel amacıdır. Avrupa birliği ve Uluslararası Çalışma Örgütü raporlarından diğer ülke uygulamalarını değerlendirmek ve Türkiye uygulamalarını kıyaslamak ise ikincil amaçtır. Buna göre, Türkiye’de salgın zorlayıcı sebep olarak kabul edilmiş ve kısa çalışma ödeneğinden yararlanma şartları hafifletilerek yaygınlaşması sağlanmış, işverenlere sağlanan desteklerle çalışanlara iş ve ücret güvencesi sağlanmaya çalışılmıştır. Ayrıca fesih hakkı sınırlandırılarak ahlak ve iyi niyet kurallarına aykırılık halleri hariç işten çıkarmalar yasaklanmıştır. İşverenlere işçiyi ücretsiz izne çıkarma hak ve yetkisi tanınmıştır. Ücretsiz izin süresince gelirden yoksun kalacak olan işçiye İşsizlik Sigorta Fonundan karşılanmak üzere nakdi ücret desteği imkânı getirilmiştir. Bu bağlamda Türkiye, diğer dünya ülkeleri ile benzer düzenlemelerle ücreti görece korumaya almıştır.
A New Set of Automated Methodologies for Estimating Site Fundamental Frequency and Its Uncertainty Using Horizontal-to-Vertical Spectral Ratio Curves
Authors: Yazdi Mohammad , Motamed Ramin , Anderson John G. 
Published: March 2022

AbstractThis study proposes a new set of methodologies to estimate the site fundamental frequency using the horizontal-to-vertical spectral ratio (HVSR) of recorded surface ground motions. Because of the lack of consensus in HVSR calculation among researchers, a wide range of methods are practiced in this area, yielding different site fundamental frequencies at a given site due to analyst subjectivity. In this study, current practices for combining horizontal components—geometric mean and RotD50—are examined first, and results show that both methods provide comparable HVSR curves. However, RotD50 has the advantage of being orientation independent. Second, the application of Fourier amplitude spectrum (FAS) and 5% damped pseudospectral acceleration (PSA) in computing HVSR is studied, and results are presented for one case study in which PSA-based HVSR seems to suffer from scenario dependency, whereas the FAS-based results appear stable. Different values for Konno–Ohmachi smoothing parameter b were evaluated, and its effect on estimating the site fundamental frequency was considered; using b = 40 is our preference. In previous studies, average HVSR curves were used to estimate a single number representing the site fundamental frequency without incorporating uncertainty. This study proposes four methodologies that use events’ individual HVSR curves to estimate the site fundamental frequency and its associated uncertainty in a completely automated manner. Methods 1–3 use individual HVSR curves to find the maximum-likelihood estimate of the site fundamental frequency (fml), whereas method 4 uses both individual and average HVSR curves to estimate the first resonance frequency (f0). To evaluate the automated methods, a subset of the Next Generation Attenuation-West2 dataset is used to study 50 stations, and the results are compared with an independent study demonstrating good consistency. The proposed methods are further illustrated using data from the Garner Valley Downhole Array (GVDA), which highlights the pros and cons of the presented methods.

Anthropometery is a measure of living subjects and had played a vital role in majority of fields there appears to be certain facial proportions and relationships that provide a basis for the diagnosis and planning for improvement of facial form. Anthropometeric measurements are used to determine facial shapes. To determine the facial index and canine relationship in Distt. Solan population. A total of 250 subjects (108 males and 147 females), aged 10- 40 years, were selected randomly. The facial proportions measured were (facial height and breadth). A digital vernier caliper was used for the measurement of facial proportions. The total facial index was calculated and the results obtained were analyzed statistically using the t-test. There was a no significant difference in the facial parameters and canine relationship when males were compared with the female subjects. The dominant phenotype in the studied population was Mesoprosopic. Class II canine relation was most common in the overall population. The data obtained in our study may be useful in anthropological research, forensics, genetic research, as well as in medical clinical practice.
Wizualność współczesnej kultury
Authors: Kawecki Witold 
Published: March 2022

Kultura współczesna pozostaje pod dużym wpływem komunikacji i kultury wizualnej. Rewolucja ikoniczna czyli tzw. „zwrot piktoralny” doprowadził do zdominowania przez obraz społecznej i kulturowej rzeczywistości. Z jednej strony ma to pozytywny skutek pozwalając dostrzec i poznać obszary, które były dla człowieka niezauważalne. Z drugiej, ekspansja wizualności marginalizuje funkcje słowa i spłaszcza poznawanie rzeczywistości. Artykuł usiłuje pokazać co jest istotą kultury wizualnej, jakie są jej ścisłe powiązania z kulturą medialną, a także jak mocno wpływa ona na kształtowanie się nowego modelu teologii, zwanej wizualną. Podjęcie tematyki teologicznej w kulturze wizualnej ma wielkie znaczenie zarówno dla studiów kulturoznawczych jak i dla teologii, prowadząc do wspólnych badań interdyscyplinarnych nad fenomenem obrazu.

Este texto analisa os tensionamentos enfrentados pelas Universidades brasileiras, principalmente as públicas, a partir da contextualização histórica de sua origem. Tais movimentos institucionais remetem a própria crise de valores, vivido por essa instituição, no seu processo de produção e difusão do conhecimento. Esta tensão será discutida a luz do conceito de Extensão Universitária, e do pensamento de Boaventura de Sousa Santos sobre a Universidade. A luta de Córdoba, 1918, após 101 anos, continua atual para as realidades das universidades latino-americanas. Autonomia universitária, gratuidade do ensino, democratização do acesso e da gestão, integração universidade/movimentos sociais, renovação dos métodos de ensino, práticas de extensão universitária sintonizadas com as necessidades sociais locais, são valores extremamente atuais e continuam na ordem do dia no Brasil. Conclui-se que a Extensão universitária vem sendo pauta de discussões e debates desde os anos de 1918, por ocasião do movimento de Córdoba, também tem sido defendido por estudantes, professores, Pró Reitores e pela sociedade em geral, por ser a principal forma de intervenção da universidade na realidade social, especialmente, após a influência Freiriana, a partir dos anos de 1960 com a concepção de extensão universitária popular.

Abstract
The pine sawyer beetle, Monochamus alternatus Hope, is a devastating wood borer of several species of pine trees, and the main transmitting vector of the pine wood nematode, Bursaphelenchus xylophilus (Steiner et Buhrer) Nickle (Aphelenchida: Parasitaphelenchidae). To explore new techniques for prevention and control of this destructive beetle, a novel gene vacuolar ATPase subunit H (V-ATPase H) was chosen as RNA interference (RNAi) target gene. Relative expression of V-ATPase H in different tissues and silencing efficiency in an in vitro RNAi experiment was assayed by using reverse transcription–quantitative polymerase chain reaction. The results indicated that the mRNA abundance of V-ATPase H in the gut was significantly higher than that in fat body, residual body, and hemolymph. Double-stranded RNA (dsRNA) targeting V-ATPase H was able to silence the expression of target gene effectively at 24 h posttreatment. Expression of immunity-related genes was examined after treatment with dsRNA targeting V-ATPase H, and transcript levels were compared with the control. The results showed that RNAi suppression of V-ATPase H inhibited the expression of immunity-related genes. This is the first demonstration of an in vitro RNAi experiment in any insect hemolymph that provides a novel environment for evaluating RNAi in insects, as well as shows potential for developing RNAi-mediated strategy for the control of M. alternatus.

La ingesta de microplásticos (MPs) en diversas especies marinas ha sido reportada en la literatura, sin embargo, el grado de contaminación en los sistemas y la biota asociada a estos es poco conocido. En este estudio se presentan los resultados de la presencia de microplásticos en siete especies de peces pelágicos y de una especie de crustáceo bentónico, todos de alto nivel trófico del Parque Nacional Marino Las Baulas.
Mediante digestión química e inspección visual se extrajeron microplásticos del sistema digestivo de 56 individuos. Un total de 90 piezas fueron extraídas del 89% de los peces (93% fibras) con 3,75±1,70 (SD) microplástico/pez. Se determinó una cantidad significativamente menor en los crustáceos con un total de 58 piezas extraídas del 76% de los individuos analizados con 2,64±1,36 (CF) microplástico/jaiba. Se realiza una búsqueda de microplásticos en tejidos musculares mediante la técnica de histología y se encontraron lesiones en el tejido muscular de los peces, pero los resultados no fueron atribuibles a MP, por ende, no se ahondará en estos datos.
Este artículo reporta la presencia de estos contaminantes en especies marinas de alto nivel trófico en la costa del Pacífico de Costa Rica, lo cual confirma la afectación por plásticos en la zona de estudio, reforzándose la necesidad de una gestión adecuada de los residuos sólidos generados por la población, tanto en la zona terrestre como en la zona marítima.

Abstract
The dorsal hippocampus (dHIP) is involved in avoidance behaviors regulation. It is unclear how experiences affect avoidance behaviors and the neuron morphology modulated by corticotrophin-releasing hormone (CRH) signaling and oxytocin receptor (OTR) system in the dHIP. We studied the effects of neonatal maternal deprivation (MD) and post-weaning environmental enrichment (EE) on the avoidance behaviors and neuron morphology of the dHIP in male BALB/c mice. We found that MD impaired avoidance memory, whereas EE improved that. MD increased Nissl bodies and neuronal complexity in the CA1 but decreased synaptic connections in the CA2–3 and DG. EE restored the Nissl bodies and neuron complexity alterations induced by MD in the CA1 and the synaptic connections alterations induced by MD in the CA3. MD increased CRHR1 levels in the CA1 and CA3 but decreased CRHR1 levels in the CA2. The effects of EE on the CRHR1 levels depend on whether MD or not. For MD mice, the EE treatment decreased CRH levels of the CA1–3 but only reduced the CRHR1 level of the CA3 region. MD probably increased OTR levels in the CA1, and EE could restore. Our study illustrates how MD and EE affect avoidance behaviors, hippocampal neuron morphology, and the OTR-CRHR1 balance. The results show that the alterations in dHIP’s regions induced by early life stress are partially restored by the late-life environmental improvement.

Abstract
Background Frailty plays a crucial role in cancer patients who have received surgery in this recent aging society. We aimed to investigate frailty as a prognostic factor in elderly gastric cancer (GC) patients who underwent curative gastrectomy. Methods In this study, we analyzed 86 elderly (over 75 years old) GC patients who underwent curative gastrectomy. Frailty was defined as clinical frailty scale score of ≥ 4. Patients were assigned to two groups; frailty group (n = 29) and no-frailty group (n = 57). Clinicopathological values, including comorbidity, immune-nutritional score, and long-term outcomes, were compared between the frailty and no-frailty groups.Results The frailty group displayed a positive correlation with a previous history of symptomatic stroke (p < 0.05). Moreover, the overall survival (OS) rate was significantly poorer in the frailty group (5-yr OS; frailty group 52.09% vs. no-frailty group 72.02%, p < 0.05). By contrast, there were no significant differences in both the cancer-specific survival (5-yr CSS; frailty group 82.33% vs. no-frailty group 89.32%, p = 0.14) and the disease-free survival (5-yr DFS; frailty group 74.68% vs. no-frailty group 86.91%, p = 0.33). Finally, frailty, differentiation, surgical procedure and the lymphocyte c-reactive protein ratio were identified among clinicopathological factors as independent prognostic factors for OS in multivariate analysis. Conclusion We identified the clinical impact of frailty as an independent prognostic factor for elderly GC patients who underwent gastrectomy.
On the cost competitiveness of blue and green hydrogen

Published: March 2022

Abstract
Hydrogen is indispensable for climate change mitigation; yet, it is unclear to what extent blue hydrogen from natural gas with carbon capture and storage will complement green hydrogen from renewable electricity. Today, green hydrogen costs are higher than those of blue hydrogen, and, despite huge cost reduction potential, it is uncertain when cost parity will be achieved. However, by combining data on costs and life-cycle emissions, we show that hydrogen’s competitiveness is increasingly determined by carbon costs associated with different life-cycle emissions across fuels. To become competitive, green hydrogen requires > 90% renewable electricity input, whereas blue hydrogen requires > 90% net CO2 capture rates and close-to-zero methane leakage. For a broad parameter range, we show that by 2035-40, green hydrogen can become the cheapest hydrogen option. Low-emission blue hydrogen may play a valuable role in bridging the scarcity of green hydrogen; yet, depending on regional circumstances it may have a limited window of competitiveness.
Basal type Takotsubo Syndrome in the post-ictal period – A case report highlighting the importance of post-ictal cardiac evaluation

Published: March 2022

Abstract
Takotsubo syndrome (TTS) is a reversible form of left ventricular dysfunction commonly associated with physical or emotional stress. It is characterised by chest pain and elevated troponin levels, thereby mimicking acute coronary syndrome however there is typically no evidence of obstructive coronary artery disease on invasive angiography. TTS is characterised by apical ballooning or akinesis with basal hyperkinesia. Basal type Takotsubo Syndrome (bTTS) is a less common atypical variant identified by basal akinesis and apical hyperkinesis. Although both forms have been shown to be associated with neurological disease and intracranial haemorrhage or ischaemic stroke, bTTS in the context of epileptiform seizures is relatively rare but an important diagnosis to recognise. We describe a case of a 73-year-old woman who presented to hospital with generalised tonic clonic seizures, followed by centralised chest pain, troponin elevation due to bTTS. This case describes an uncommon presentation of bTTS and highlights the importance of cardiac assessment in patients presenting with generalised tonic-clonic seizures.
