Authors: Kaur Gagandeep , Kapoor Rahul , Sharma Priti , Srivastava Puja
Published: June 2021

Assessment of genetic diversity between selected genotypes serves as an essential tool to exploit the genetic variability. In the present study, Ninety nine accessions of oat acquired from different geographical regions were used to study the molecular genetic variability by the use of 91 microsatellite primers. A total of 248 alleles from 91 primer pairs in the 99 oat genotypes were detected. The average alleles per primer pair were recorded as 2.69. The primer pairs having the highest PIC values viz., AM 6 (0.50), AM 55 (0.49) and M 83381 (0.49) can be further used in the association mapping studies. Clustering of the oat genotypes into two main clusters A and B was done by using the symmetric matrix of DICE coefficient based on UPGMA method in Software – DARwin 6.0. In this study, the moderate amount of dissimilarity was observed between the whole set of accessions, the values ranging from 0.33 to 0.79. The individuals belonging to the different clusters may be useful in hybridization studies of oat improvement programmes.

Published: June 2021

The process of screening for fertility restoration trait involves test crossing with a set of cytoplasmic male sterile (CMS) lines and evaluation of F1 hybrids for pollen and spikelet fertility. In the present study, F2 mapping population derived from a cross, APMS 6A × RP 5933-123 was utilized to map Rf genes. The F2 population was also genetically analysed for pollen and spikelet fertility percentage. Chisquare (?2) analysis to showed that the fertility restoration trait followed expected digenic ratio. By bulk segregant analysis (BSA) likely Rf genes containing regions were located on chromosome 10. The SSR markers viz., RM304, RM258 located on chromosome 10 and RM23958 located on chromosome 9 showed clear polymorphism between two groups of fertile and sterile bulks. Based on BSA linkage analysis and F2 population, pollen and spikelet fertility analysis along with molecular screening results of Rf linked markers, it is concluded that Rf4 gene located on chromosome 10 is playing major role and contributing to 90% of fertility restoration trait of newly derived restorer line RP5933 along with minor effect genes from chromosome 9. The findings may be useful for rice hybrid breeding.
Inheritance of photo-sensitivity in pigeonpea
Authors: Saxena K. B. , Wallis E. S. , Chauhan Y. S. , Byth D. E.
Published: June 2021

Pigeonpea [Cajanus cajan (L.) Millsp.] is a short-day legume species and the late maturing genotypes are more photosensitive than early types. To generate information about the inheritance of photo-sensitivity, this study was conducted under natural and artificially extended (16 h) photo-periods using F1, F2 and BC1F1 generations. Under natural photo-period, F1 hybrids showed partial dominance of earliness; while in F2 , a normal distribution that was skewed towards earliness was observed. In contrast under extended photo-period, the spread of F2 data was wide with discontinuities recorded at day 70, 82 and 103. Chisquare tests, when applied to F2 and BC1F1 data, suggested that three dominant genes (PS3 , PS2 and PS1 ) controlled the expression of photo-sensitivity. These genes were found operating in a hierarchical order with PS2 and PS1 genes failing to express in the presence of PS3 gene. Similarly in the absence of PS3 gene, PS2 expressed but it masked the expression of PS1 . Further, PS1 gene expressed only when both PS3 and PS2 were in recessive homozygous state. Hence, the proposed genetic model for photosensitivity in pigeonpea is PS3 > PS2 > PS1 and photoinsensitive genotype being a triple recessive (ps3ps3ps2 ps2ps1ps1 ). .

Pigeonpea [Cajanus cajan (L.) Millspaugh] is an important pulse crop grown under Indian rainfed agriculture. Twenty eight pigeonpea genotypes were tested for stability and adaptability across ten rainfed locations in the States of Telangana and Karnataka, India using AMMI (additive main effects and multiplicative interaction) model and GGE (genotype and genotype by environment) biplot method. The grain yields were significantly affected by environment (56.8%) followed by genotype × environment interaction (27.6%) and genotype (18.6%) variances. Two mega environments were identified with several winning genotypes viz., ICPH 2740 (G15), TS 3R (G10), PRG 176 (G8) and ICPL 96058 (G22). E2 (Gulbarga, Karnataka), E3 (Bidar, Karnataka) and E6 (Vikarabad, Telangana) were the most discriminating environments. Genotypes, ICPH 2740, PRG 176 and TS 3R were the best cultivars in all the environments whereas PRG 158 (G9), ICPL 87119 (G12), ICPL 20098 (G19) and ICPL 96058 (G22) were suitable across a wide range of environments. Genotypes, ICPH 2740 and PRG 176 can be recommended on a large scale to the farmers with small holdings to enhance pigeonpea productivity and improve the food security

Published: June 2021

Groundnut is sensitive to Fe deficiency under alkaline and calcareous soils and exhibits iron deficiency chlorosis (IDC) causing significant reduction in growth and yield. Genotypes were assessed for IDC related traits such as visual chlorosis rating, SPAD chlorophyll meter reading, chlorophyll and active iron (Fe2+) content across five growth stages and also for productivity traits viz., plant height, number of primary branches, number of pods per plant, pod yield, shelling per cent, 100 seed weight and haulm yield. Comparison between Fe-supplemented and Fe-nonsupplemented condition for IDC related traits showed not much difference among IDC tolerant genotypes across all five growth stages, while significant differences among IDC susceptible genotypes were observed. Maximum reduction in pod yield was observed among IDC susceptible genotypes compared to IDC tolerant and moderately tolerant genotypes. However, recently released variety G 2- 52 with moderate tolerance to IDC and higher yield potential recorded higher pod yield both under Fe applied (1754 kgha–1) and non-applied conditions (1544 kgha–1).

Outliers are a common phenomenon when genotypes are evaluated over locations and years under field conditions and such outliers makes studying genotype-environment Interactions difficult. Robust-AMMI models which use a combination of robust fit and robust SVD approaches, denoted as ‘R-AMMI-RLM’ have been proposed to study GEI in presence of such outliers. Instead of ‘R-AMMI-RLM’ we propose a model which uses a combination of linear fit and robust SVD to study GEI in presence of outliers and we denote this model as ‘R-AMMI-LM’. Here we prove that ‘RAMMI-LM’ was superior over ‘R-AMMI-RLM’ as it recorded very low residual sum of squares and low RMSE values. Thus proposed, ‘R-AMMI-LM’ model could explain the GEI more precisely even in presence of outliers.

Published: June 2021

All the countries have an effort in cultivating environmentally literate citizens since the governments and citizens are responsible to protect the environment. Turkey is one of these countries which integrated environmental education topics and objectives into the science curriculum. Different frameworks have been developed to assess individuals' views about, attitudes and behaviors towards the environment and address environmental issues. These frameworks mostly focus on environmental literacy, but they do not emphasize environmental citizenship. Assessment of the curriculum through the lens of a framework that grounds on both environmental literacy and citizenship is important and needed in order to cultivate environmentally literate citizens. Therefore, this study aimed to investigate the extent to which the newly developed science curriculum provided the opportunity to constitute environmental literate citizenship at the 5th grade level. We benefited a coherent framework grounded by environmental literacy and environmental citizenship in our inquiry to analyze the curriculum. Included among the data collection sources were curriculum documents, objectives, and learning and assessment activities at the 5th grade level. The data analysis consisted of two steps: (i) analysis of the objectives and (ii) content analysis of the human and environment unit at the 5th grade science textbook within the context of environmental literate citizenship. Our findings indicated that the objectives under environmental citizenship required social action and these objectives were associated with critical environmental literacy. In conclusion, the content had the potentiality to help students develop critical viewpoints about environmental issues from critical environmental literacy and justice-oriented citizenship aspects and take social action to make a change in their environment.

Since textbook evaluation is a prominent task for educational development, hence, the study is motivated to extend the ideas towards the best of English as a foreign language teaching in high schools. Globally, the English language is taught aligned with 21st century skills, yet textbooks are lacking some of these skills and approaches in Afghanistan. Therefore, the study applied a mixed-method to critically evaluate the 12th grade English language textbook of high schools in Afghanistan. The data is collected using an adopted textbook evaluation checklist and a Likert-Scale ranging from “Poor” to “Excellent”. Content analysis is used to interpret and describe the meaning qualitatively from the number scale of the item in the checklist. Likert-Scale is also analyzed separately through SPSS. The results show that the aims of the course did not correspond closely to the aims of the teaching program and the needs of the learners in the textbook. However, the layout of the textbook is clear, and the students can find their way if an individual study is intended. In terms of the skills, the textbook stated that it covers all four skills of language learning, but the evaluation indicates a considerable focus on reading, grammar, and vocabulary. In conclusion, the study highlighted that the textbook requires to be updated to be focusing more on topic contents related to the needed skills and to make it more user-friendly. This contributes to promoting textbook development in the Ministry of Education and provides an in-depth understanding of the current status of the available textbooks in the high schools of Afghanistan.

Published: June 2021

Religious moderation has become a new and unique issue discussed by the Ministry of Religion of the Republic of Indonesia. Universities are held to be a platform for promoting religious moderation through the learning process. Integrating religious moderation in the learning process is the main alternative to increase understanding of religious moderation in educational institutions, but there are only a small number of research and technical guidelines for subjects with a religious background such as Islamic religious education. Therefore, this study intends to instill religious moderation values in English language learning through cross-cultural understanding. The CCU course is suitable for negotiating an understanding between cultures and religions, especially in the context of the multicultural society of Indonesia. This research used a descriptive qualitative method, instruments being analysis sheets of RPS documents, research rubrics, and student learning outcomes in the CCU course, library research to obtain more detailed information on the value of religious moderation, field notes on observations in class; and an 8-item questionnaire. Results reveal that universities integrate religious moderation values, such as tolerance, national commitment, accommodating to the local culture, and anti-violence, into the learning process. The researcher connected religious moderation values with learning outcomes of CCU and implemented it in the learning process by using some methods such as group presentation, debating, watching a movie. This study proved that instilling religious moderation value through CCU course improved the students’ values, understanding and awareness of religious moderation. This study contributed to the Indonesian Ministry of Religion’s mission to make Islamic higher education a place for instilling the value of religious moderation, especially to students as the nation's future leaders and generation.

The Covid-19 pandemic condition that has hit the world has had a significant impact on various sectors. Health facilities need information system support in their services. Breaking the distribution chain can be done by maintaining a physical distance. However, in reality, people are still indifferent. There is a possibility that the patient is infected but shows no symptoms or is lying to the point of endangering medical personnel. In addition, there is a stigma in the community so that they are afraid to go to health facilities. Even though it cannot be denied that in certain conditions patients should still have their conditions checked by a doctor. The development of this online registration system aims to reduce the risk of contact between patients and medical personnel. The real-time queue monitoring feature helps patients to wait in line anywhere, so they are not in the patient's waiting room. This system is able to provide real-time queues for examinations in all polyclinics. This can reduce public anxiety about coming to health facilities.

The objective of the present paper is to clarify the effect of defect length in depth direction on rolling contact fatigue (RCF) crack propagation in high strength steel. RCF test and synchrotron radiation micro computed tomography (SR micro CT) imaging were conducted. In the case of the defect with the 15 ?m diameter, flaking life decreased with increasing defect length. In a comparison of the CT image and the SEM view, the shapes of defects and the locations of the horizontal cracks were almost the same respectively. The mechanism of RCF crack propagation was discussed by finite element (FE) analysis. Defects led to higher tensile residual stress than that without defects in the region where the defect exists. The shear stress range at 0.1 mm in depth on the middle line of the defect and the range of mode II stress intensity factor at the bottom of a vertical crack increased with increasing defect length.
Crack growth behavior of aluminum alloy 6061 T651 under uniaxial and biaxial planar testing condition
Authors: S. Henkel  , E. Liebelt  , H. Biermann  , S. Ackermann
Published: June 2021

The crack growth behavior of the aluminum alloy 6061 T651 was investigated using cruciform specimens with a measurement area of 120 x 120 x 2 mm3 with two center crack configurations of the starting notch parallel to one of the loading axes and under an angle of 45°, respectively. For the case with crack direction in one of the loading axes the load ratio R = ?min / ?max as well as the force parallel to the crack direction (resulting in different T-stresses) were changed. Crack growth rate was studied under varying T-stress. Also the retardation after single overloads was determined for R = 0.1, R = 0.5 and R = 0.8. As a result a change in T-stress does not significantly affect crack growth rate on high R ratios (R = 0.5) for constant ?F loading. In case of lower R-ratios (R = 0.1) crack growth retardation was observed at presence of a static tensile load parallel to the crack growth direction due to higher influence of crack closure. Furthermore, such tensile load results in longer retardation periods after applying an overload at R = 0.1. Less pronounced overload retardation can be assumed with tensile force FX for R = 0.8 and 1.3 times overloads. Non proportional loading with a phase shift in time between the two axes of 45° and 90° results in a mixed mode situation (mode I / mode II) at the crack tip of a crack which is orientated under 45° to the loading axes. Mode I and mode II fractions change during every cycle. A phase change of 45° did not change crack growth significantly compared with proportional load. Crack branching occurred when changing from proportional loading to non-proportional 90° phase shifted loading. The two crack tips of the center crack under 45° divided in 4 crack tips under approximately 90° to the loading axes which were simultaneous propagating for more than 10 mm. Finally, two crack tips propagated faster than the remaining two. The stress intensity factors KI and KII as well as the T-stress where calculated by FEA (ABAQUS). For the 45° crack orientation and the non-proportional load case with 90° phase shift linear elastic FEA calculations show that there are time dependent rotating principal stress axes on the crack tip during one cycle. In the unnotched (uncracked) specimen there are fixed principal stress axes also in the phase shifted loading case. The configuration with 4 cracks has a significant higher ?KI than the configuration with two crack tips while ?KII is significantly lower. In addition uniaxial crack growth measurements were performed on SENB specimen in the size of 10 x 20 x 100 mm3 covering the threshold and Paris-region for loading ratios R = 0.1, 0.3, 0.5, 0.8.

The modified disk shaped compact tension test is a configuration derived from standard compact tension test that is used for measuring fracture mechanical properties of primarily metallic materials. The compact tension configuration is commonly used for measurement fracture mechanical properties as e.g. fracture toughness, Young’s modulus, work of fracture etc. The modified compact tension tests imply significant modifications of the specimen morphology in order to avoid premature failure. The modified compact tension test is not proper for quasi-brittle materials due to its complicated shape (steel-concrete interface), but it is easily extracted from drill core and we do not need large amount of material for obtaining fracture properties as we need for e.g. three- or four- point bend test. Since it is a new test method, a wide range of tests is needed to be done before it can be applied. In the paper the selected outputs of the experiments performed on normal and high strength concrete will be processed and the values of fracture mechanical parameters will be discussed.

Background: A new corona virus was subsequently identified and was temporarily named the 2019 new corona virus. On 30th January 2020, the World Health Organization (WHO) announced that the emergence of a replacement corona virus (2019-nCoV) was a public health emergency of international concern. Infectious diseases became one among the main threats to global public health within the twenty first century; such diseases impact both physical health and psychological state. PTSD in youth is common and debilitating. In contrast to adult PTSD, relatively little is understood about the neurobiology of paediatric PTSD. This study is an effort to explore the Assessment of suspected covid 19 children for perceived levels of stress during covid 19 outbreaks.

Methods: The information required for the study was obtained through online means. Consent was obtained orally over phone before proceeding with the study. The questionnaire consisted of demographics variables and the questionnaire was shared online via Whatsapp and/or other means. The questionnaire was given in English.

The Children’s Impact of Event Scale (CRIES 13) was used and the questions were multiple choice question (MCQ) type with 1 best response. In case of the patient not having an appropriate phone they were interviewed over the phone and the collected data was statistically analysed to ascertain any significance and association between each variable.

Results: Out of 54 children, two of them were found to have a score of 30 on CRIES ScaleConclusion: The findings of the study suggest that paediatric PTSD is almost identical to adult PTSD, which has significant p value. It is necessary to recognise the initial psychological impact of the pandemic on children and help them receive immediate attention.

Today's dentists have a variety of treatment options for restoring a smile with discoloured vital teeth. Treatment options include full crowns, veneers, and direct restorations, as well as minimally invasive procedures such as microabrasion, macroabrasion, and bleaching. Bleaching of teeth is the least invasive and conservative treatment option, so it is gaining popularity. The purpose of this case report is to describe an in-office vital tooth bleaching case in a young patient using POLA OFFICE + (37.5%percent hydrogen peroxide gel). By the end of the second visit, the results were satisfactory, with no side effects.

Araştırmanın amacı; çalışan kadınların boş zaman yönetimi ve sağlıklı yaşam biçimi davranışlarını incelemektir. Çalışmaya Mersin İl Merkezinde çalışan 342 kadın (Ortyas = 32.12± 11.81) gönüllü olarak katılmıştır. Katılımcılara Kişisel Bilgi Formu, Boş Zaman Yönetimi Ölçeği ve Sağlıklı Yaşam Biçimi Davranışları Ölçeği uygulanmıştır. Verilere ait çarpıklık ve basıklık değerleri verilerin normal dağılıma sahip olduğunu göstermektedir. Veri analizinde Pearson Korelasyon analizi ve T- Testi kullanılmıştır. Ayrıca katılımcıların demografik özelliklerinin ve ölçeklerden aldıkları ortalama puanların belirlenmesi için yüzde, frekans puanları incelenmiştir. Araştırmada; çalışan kadınların boş zaman yönetimiyle sağlıklı yaşam biçimi davranışları arasındaki genel olarak pozitif yönlü, orta düzey ilişki tespit edilmiştir. Medeni durumun sağlık algısı ve boş zaman yönetiminde anlamlı farka yol açan bir değişken olduğu tespit edilmiştir. Katılımcıların boş zaman yönetimi ve sağlıklı yaşam biçimi ölçeği puanlarının kurum değişkenine göre istatistiksel olarak anlamlı bir farklılık göstermediği tespit edilmiştir. Sonuç olarak; boş zamanını daha iyi yönetebilen kadınların sağlıklı yaşam biçimi davranışlarında da olumlu davranışlar sergilediği söylenebilir. Çalışan kadınların boş zaman yönetiminde ve sağlıklı yaşam davranışlarında, özel sektörde ya da kamu da çalışmaları anlamlı bir fark yaratmazken evli olup olmamaları anlamlı farka sebep olmuştur. Son olarak sağlıklı yaşam davranışını etkileyen ana faktörlerin evli katılımcılarda “kişiler arası iletişim”, bekâr katılımcılarda ise “manevi gelişim” olduğu söylenebilir.
Yeni Kapitalizm ve Türkiye’de Tarım Sektörünün Dönüşümü

1970’lerde yaşanan petrol ve kapitalizmin içsel krizi ile kapitalizm yeniden bir yapılanma sürecine girmiştir. Bu süreç günümüze kadar devam etmiş ve aslında özünde kapitalizmle aynı sermaye birikim mekanizmasını başka bir formda devam ettiren bir sistem haline gelmiştir. Bu sistem literatürde yeni kapitalizm, post-Fordizm, neo-liberalizm, örgütsüz kapitalizm, esnek üretim tarzı ya da küreselleşme gibi pek çok kavramla karşımıza çıkmaktadır. Farklı kavramlarla da olsa bir üretim tarzı olarak sermaye birikim mekanizması bu formda devam etmektedir. Uluslararası kuruluşlar aracılığıyla sermaye birikim mekanizmasının dünya ölçeğinde var olmadığı en ufak bir nokta kalmamıştır. Gelişmiş ülkeler, özellikle azgelişmiş ve gelişmekte olan ülkelerde bu yeni sistemi aktarmak ve oralardan bir sermaye birikimi elde etmek için, bütün ülkeler için hayati ve stratejik önem taşıyan tarım sektörüne politika önerileri uygulatarak baskıları altına almışlardır. 1980 yılında Türkiye’de uygulanmaya başlayan neo-liberal politikalar, sosyoekonomik ve stratejik önemi yüksek olan tarım sektörünün bir dönüşüm sürecine girmesine neden olmuştur. Bu çalışmanın amacı, bu dönüşümü anlatmak, etkilerini analiz etmek ve Türkiye tarımını tarihsel bir bağlamda irdelemektir. Bulgulara göre, kuruluşundan 1980’e kadar tarım üzerinde yoğun olarak korumacı ve destekleyici politikalar uygulayan Türkiye, 1980’de neo-liberal politikaları benimsemesiyle bu korumacı politikalardan vazgeçerek tarım sektörünü serbest piyasaya açık hale getirmiştir.

Platon ve Aristo’dan günümüze, tarihi süreç içerisinde, “şiir” ve “şair” üzerine birçok tanım yapılmış ve poetik görüşler dile getirilmişse de şiire dönük hislerin kalıplara dönüştürülmesi konusunda standart bir bakış açısı geliştirilmemiş; kavramlara ilişkin öznel görüşlerden oluşan formlar, günümüzde dâhi farklılık göstermeye devam etmiştir. Doküman analizi tekniği ve fişleme yönteminin işe koşulduğu bu çalışmada, hâlâ standart bir tanımı yapılamayan “şiir” ve “şair” kavramları üzerine, yaşayan bir değer olan İsmail Uyaroğlu’nun poetikasının birincil kaynağı olduğu düşünülen şiirleri esas alınmış ve sanatçının kavramlara dönük tanım ve kaynakları açıklanmaya çalışılmıştır. Çalışmanın genelinde Uyaroğlu’nun şiirlerinin ve şairliğinin kaynakları ile nitelikleri üzerinde durulmuş; esasen karakterini yansıtan eserlerinde “şiir”e ve “şair”e dönük kavramların birbiri ile tutarlı olduğu ve insana dair her türlü argümanın Uyaroğlu’nun eserlerinde şiirleştirilebildiği görülmüştür. Uyaroğlu’na göre şiir; umuttan, sızıdan, hınçtan, öfkeden, acıdan, çileden, karanlıktan, hüzünden, ölümden beslenen; kanlı, kirli, gececil, tehlikeli, yorgun, kara, lanetli, vahşi, küstah, ses çıkaran bir türdür. O, beslendiği kaynaklarını şiirlerini aracı olarak kullanarak dile getirmiş -kalender, kavgacı, savaşçı, asi, hırçın, diri bakışlı, mücadeleci, dalkılıç, lanetli, sevdası zor, meraklı, azimli, kimi zaman şaşkın, hayvan sever ve yaratıcı- bir şairdir. Sonuç olarak şairin eserlerinden hareketle ilgili kavramlara dönük tanımlarının oluşması aşamasında okurlara ve ilgililere önemli bilgiler ve farklı bakış açıları kazandıracağı da ayrıca düşünülmektedir.
