Probing SU(N)-symmetric orbital interactions with ytterbium Fermi gases in optical lattices

In dieser Arbeit wird die Erzeugung und Untersuchung wechselwirkender Ytterbium-Quantengase mit zwei elektronischen Orbitalen in optischen Gittern prasentiert. Entartete Fermigase aus Ytterbium oder anderen erdalkaliahnlichen Elementen wurden in jungster Zeit als Modellsysteme fur orbitale Phanomene in der Festkorperphysik herangezogen, wie z.B. die Kondoabschirmung, schwere Fermionen und kolossalen magnetischen Widerstand. Fur diese Gase wurde des Weiteren eine hohen SU(N) Symmetrie vorhergesagt, die aus der starken Entkopplung des Kernspins resultiert, und die Erzeugung neuer exotischer Aggregatzustande ermoglicht. Das SU(N) Hubbard-Modell mit zwei Orbitalen sowie interorbitaler Spinaustauschwechselwirkung lasst sich mit Hilfe der beiden niedrigsten (meta-)stabilen elektronischen Zustande realisieren, welche dabei die Rolle der Elektronen aus unterschiedlichen Orbitalen eines Festkorpers einnehmen. Die Wechselwirkungen in einer entarteten Mischung verschiedener Spinzustande von Yb-173 mit zwei Orbitalen werden durch die Anregung in den metastabilen Zustand in einem zustandsunabhangigen Gitter untersucht. Alle Streukanale fur die zwei Orbitale werden charakterisiert und die SU(N=6)-Symmetrie wird innerhalb der experimentellen Unsicherheiten nachgewiesen. Von herausragender Bedeutung ist der Nachweis einer sehr starken Spinaustauschwechselwirkung zwischen den zwei Orbitalen, wobei der dazugehorige Austauschprozess anhand dynamischen Ausgleichs der Spinpolarizierung zwischen verschiedenen Orbitalen beobachtet wird. Ermoglicht wird dies durch die Implementierung prazisionsspektroskopischer Verfahren sowie die vollstandige, koharente Kontrolle der Besetzung des metasabilen Zustandes. Die Verwirklichung eines SU(N)-symmetrischen Gases mit Spinaustauschwechselwirkung, des grundlegenden Bausteins fur orbitalen Quantenmagnetismus, ist ein entscheidender Schritt in Richtung der Simulation von wichtigen Vielteilchenmodellen, wie dem Kondo- Gittermodell.

Subchronic Systemic Toxicity of New Endodontic Material Based on Calcium Hydroxyapatite and Calcium Silicates

As an alternative to MTA, a new endodontic material based on hydroxyapatite and calcium silicates (ALBO-MPSA) has been synthesized, and its biocompatibility has been studied in manyin vitroandin vivostudies. The current study aims to evaluate a subchronic systemic toxicity of ALBO-MPSA on the rat animal model, as a continuation of the previous studies. Biochemical parameters of blood and histological parameters of the liver, kidneys, and spleen of the rats were analyzed after 120 days of consumption of the aqueous extract of ALBO-MPSA. The results showed no myelotoxic effect or autoimmune effect on peripheral blood cells and no pathological effect on the liver, kidney, and spleen tissues. Besides, no changes in the skin and hair of the rats, neither the change in the consumption of food and water, nor the change in their usual behavior were noticed during the experiment.
Factors Influencing Orderly Transition to Online Deliveries during COVID19 Pandemic Impact

With the spread of COVID 19, almost every higher educational entity initiated online delivery whereby teaching is undertaken remotely on digital platform. A massive shift like this arises an onslaught of questions. A case study was conducted in March and April 2020 to determine the challenges affecting the adoption of e-learning in 6 university colleges in Sri Lanka. A comprehensive literature survey was carried out. A questionnaire survey was administered to 90 teachers and 650 students and analyzed through the use of simple descriptive statistics. Besides, a narrative analysis was undertaken to identify shared views expressed in a series of telephonic inquiries. It was found that data as it is a survey based paper. The paper concludes with some solutions implementable in three stages. The findings of the study will help work out a digital policy, revisit the existing educational taxonomies and enhance the effectiveness of online delivery particularly in a future context similar to COVID 19.
Weak Street-level Enforcement of Tax Laws: The Role of Tax Collectors’ Persistent but Broken Public Service Expectations

Abstract What drives ineffective tax collection in developing countries? This widespread phenomenon has been explained by weak ‘state capacity’, rent-seeking bureaucrats, or the influence of political elites. More recently, scholars have also emphasised the role of ‘moral economies’, shared notions of what constitutes fair and legitimate taxation that prevent tax collectors from strictly enforcing the law. However, the literature has thus far missed the ways in which shared notions of what constitutes fair work and employment in the tax administration affect collection. Drawing on two years of fieldwork in Egypt, including ethnographic research among street-level tax collectors, the article finds that the simultaneous persistence and disappointment of historical expectations and feelings of entitlement to a white-collar, middle-class job renders tax collectors unwilling to carry out vital enforcement tasks, and further impedes the building of administrative capacity. Furthermore, the administrative leadership’s buying-into such narratives hollows out its capability to incentivise tax collectors to change their ways. These findings have important implications for our understanding of the micro-foundations of governance and state capacity, underscoring the role of normative-ideational factors not only in shaping the willingness of taxpayers to pay taxes, but also of tax collectors to collect them.
Analyzing Antecedents and Consequence of Job Crafting

The purpose of this study was to investigate the antecedents and consequence of job crafting in the context of education sector and high-power distance societies, such as Indonesia where most people seem hesitant to seize on job crafting due to their appreciation to organizational hierarchies. Specifically, we examined perceived organization support, job demand, and job autonomy as the antecedents to job crafting. Further, we tested the effect of these associations on job engagement as the consequence. According to job demand resources theory, employees voluntarily modify their job aspects (job crafting) when they perceive organization support, experience high work demand, and satisfy with the degree of autonomy. Consequently, this leads to the enhancement of employee’s engagement level. To investigate these relationships, a survey was conducted among 287 early childhood and primary school teachers working in 16 schools in Bandung, West Java, Indonesia. We used path analysis to test the hypothesized models. The results indicate that perceived organization support, job demand, and job autonomy are positively associated to job crafting. In addition, we found that when job crafting is present, it increases the level of employee engagement. This study highlights the importance of job crafting for early childhood and primary school teachers working in the high-power distance societies. of the teachers in the future because they experience organizations’ support. Our study also contributes to the literature in several ways. First, this study examined the antecedents and consequence of job crafting in a sample of high-power distance orientation setting. It fills the gap in literature and provides an empirical evidence in a setting where people concern on the hierarchies and tend to avoid job
Raman studies of the structure of niobium oxide/titanium oxide (Nb2O5.TiO2)

The structure of titania-supported niobia has been investigated by means of Raman spectroscopy. Well-dispersed monomeric and oligomeric species are observed at low Nb loadings corresponding to 0.13 of a theoretical Nb[sub 2]O[sub 5] monolayer, whereas amorphous islands of Nb[sub 2]O[sub 5] are the dominant species at Nb loadings corresponding to >0.5 of a theoretical Nb[sub 2]O[sub 5] monolayer. Water vapor coordinates reversibly with Nb=O groups at the surface of the dispersed niobia, through the formation of Lewis acid-base adducts. The Nb-O-Nb bonds in the oligomeric species appear to undergo hydrolysis upon H[sub 2]O exposure unlike the Nb-O-Nb bonds in the amorphous Nb[sub 2]O[sub 5] islands, most of which are in the bulk of the oxide and, hence, less accessible to interaction with H[sub 2]O. Calcination between 500 and 700[degrees]C does not affect the structure of the supported Nb[sub 2]O[sub 5] although some of the amorphous Nb[sub 2]O[sub 5] is transformed into T-Nb[sub 2]O[sub 5]. It is proposed that the amorphous Nb[sub 2]O[sub 5] is stabilized on the surface of TiO[sub 2] by the formation of Ti-O-Nb linkages. The dispersed Nb[sub 2]O[sub 5] is found to stabilize the transformation of the TiO[sub 2] support from anatase to rutile and the coincidentmore » loss in surface area of the support. Further calcination to 800 and 950[degrees]C results in the formation of TiNb[sub 2]O[sub 7]. 42 refs., 12 figs., 1 tab. « less

Endophytic Fungi from Sorghum bicolor (L.) Moench: Influence of Genotypes and Crop Systems and Evaluation of Antimicrobial Activity

Endophytic fungi (EF) colonize plant tissues without causing damage; this relationship brings benefits to both, including a greater resistance to environmental stresses, but the influence of genotypes and culture system in endophytic community is still unraveled. Thus, this work aimed to study EF from Sorghum bicolor and correlate to its genotypes submitted to different culture systems; their potential to produce antimicrobial compounds was also evaluated. To optimize the production of metabolites, four isolates were submitted to liquid medium and the crude extracts of different culture times were analyzed. EF of leaves of Qualimax and SF15 genotypes were isolated after superficial disinfection. Fungal identification was made using classical taxonomy. As results, the traditional system presented the lowest number EF isolates, while the minimum system showed the highest. The genera Aspergillus, Fusarium, Penicillium, Cladosporium, Curvularia and Syncephalastrum were found; Aspergillus spp. was pointed out as a predominant endophyte of genotype Qualimax. Among the 25 endophytes submitted antimicrobial activity assay in solid medium, 21 presented antibacterial activity against at least one bacterium with the highest inhibition zone of 29.3 mm of diameter against Staphylococcus aureus. All EF submitted to liquid medium kept the capacity to produce antibacterial metabolites. In conclusion, regardless of genotype and culture system, sorghum is colonized by different EF, mainly Aspergillus spp. EF from leaves of S. bicolor produce antibacterial compounds and their biotechnological applications can be explored in future.
Toward a Global Urban Sociology: Keywords

Many cities in the Global South are structurally different from the Northern, particularly American, cities on which much of urban sociology’s conceptual apparatus has been based. Thus, depicting them in terms of a standard urban vocabulary risks imposing an inappropriate way of seeing. We need a vocabulary that is able to accommodate their different urban experience. This special issue contributes to the work of building that vocabulary. We select five keywords in urban sociology—eviction, segregation, suburbs, violence, and gentrification—and reconstruct them in light of the places we study (India, China, Mexico, the Philippines, and South Africa). Our aim is to produce a set of keywords better equipped to travel South and, in the process, advance a truly global urban sociology.
The Late Ottoman Şarkı and the Interweaving of Registers: Towards an Ideology of Song

This paper investigates the sarki song form, composed in the late nineteenth century, discussed with regards to the linguistic registers that characterised the use of Turkish in the same period. It considers the production and circulation of this popular vocal repertoire in relation to reforms in language education and an intense, public conversation about the place of Turkish in a society on the verge of a controversial modernity. My aim has been to suggest new ways of thinking about the role of song in supporting or subverting – and occasionally, both – language practice and efforts at standardisation, as well as considering it in the more general framework of language debate. The material chosen is a small group of songs appeared in the newspaper Ma’lumât in December 1895. By particularly focusing on the way that various registers interweave in the texts, I have suggested that we look at this repertoire as a reflection of wider linguistic/cultural tensions. While Ottoman-period Turkish has often been regarded as an unreadable, impenetrable language belonging to the elites, the case of the sarki and its urban, newspaper reading public suggests that we should begin looking at it as a language spectrum encapsulating a multitude of registers, chosen according to the intended meaning and occasion. I propose to consider song in its capacity to maintain affections and authority, as well as providing a tool for self-mapping in history and tradition. In the late Ottoman scenario, this translates into reconsidering notions of cultural and social schisms in favour of a fluidity in both language and music practice, that is manifest in the sarki text.
Stopping crime? The effect of crime re-enactments on eyewitness memory

Crime re-enactments broadcast on television encourage witnesses to provide information regarding unsolved crimes. However, given that eyewitness memory can be altered through exposure to post-event information, it is possible that crime re-enactments may influence the memory of eyewitnesses. The current studies examined the effects of crime re-enactments on eyewitness memory. In two experiments (Experiment 1 with a distractor task, Experiment 2 without a distractor task), participants were shown one of three versions of a crime video that differed in their ambiguity. One week later half of the participants viewed a crime re-enactment. All participants then completed a guided free- and cued-recall task regarding the original event. Across both studies, exposure to the re-enactment did not improve eyewitness memory; instead, participants who viewed the re-enactment were more likely to accept the misinformation in the re-enactment. The findings shed light on potential issues with using crime re-enactments to elicit eyewitness accounts.
EFFECT OF SEASON ON GROWTH PERFORMANCE AND IMMUNITY TRAITS IN RABBITS

The present study was carried out to investigate the effect of season on growth performance traits, leptin hormone concentration and gene expression for innate immunity in response to vaccination against pasteurellosis. A Total of 384 weaned rabbits were used in this study. They were from females of APRI line, a local population. Rabbits weaned at 33-35 days and introduced in the experiment at weaning. Arbitrarily, weight at beginning was considered as the "5 weeks" weight. All rabbits were weighed every 7 days and the feed consumption measured at the same weekly interval until all rabbits were 12 weeks old. Leptin hormone level in serum was assayed. Vaccination with Pasteurella multocida was studied in a challenge experiment. Gene expressions for interleukin-6 (IL-6) and toll-like receptor-4 (TR4) were assayed by Real Time-PCR. Parameters of the antioxidant status were included reactive oxygen species, (ROS) expressed as H2O2, Lipid Peroxide, expressed as malondialdehyde and glutathione peroxidase. Blood samples were taken at 8, 10 and 12 weeks of age, respectively. The body weights in winter at W5, W8and W12 of age were higher than those in others seasons. Season had a significant (P≤0.05) influence on daily gain and feed intake. Season had no significant influence on Leptin hormone level in growing rabbits. Vaccination with Pasteurellamultocida led to an increase in gene expression for IL-6 in autumn and winter. Expression for IL-6 in spring has the lowest values. Gene expression of TR4 in rabbits under different seasons was not significantly different. It is can cluded that vaccination by Pasteurellamultocida needs some additives to enhance immunity especially during summer and spring seasons.
How risk perception influences CEOs' technological decisions: extending the technology acceptance model to small and medium-sized enterprises' technology decision makers

PurposeThis paper aims to investigate the factors influencing chief executive officers’ (CEOs') intentions to implement cloud technology in Italian small and medium-sized enterprises (SMEs). Design/methodology/approachThe study proposes a model that integrates the theoretical construct of the technology acceptance model (TAM) with a classification of perceived benefits and risks related to cloud computing. The study employs a structural equation modeling approach to analyze data gathered through a Likert scale-based survey.FindingsThe findings indicate that risk perception has a strong negative effect on the intention to introduce cloud technology in firms. This effect is partially offset by the perceived ease of use of the technology.Originality/valueThe study provides a new theoretical framework that integrates the TAM and a classification of perceived risks to provide a clear view of management's cognitive processes during technological change. Moreover, the results show the main factors influencing decisions regarding the implementation of cloud computing in firms in light of the perception of risks. Finally, this study provides interesting findings for cloud service providers (CSPs) about their customers' decision-making processes.
Morphology of the Gall Bladder and Extrahepatic Ducts in the Postnatal Ages of Guinea Pig

The guinea pig (Cavia porcellus) is a rodent species of family Cavidae and the genus Cavia. It was a domesticated rodent and not found in the wild (Barbara, 1974). Guinea pigs were frequently used as model organism and for biological experimentation. Because of its robust size, it replaced other rodents like mice and rats. Guinea pigs were used as models for human medical conditions like diabetes, tuberculosis etc. Gall bladder is a small pocket like organ for the storage and concentration of bile. The concentrated bile reaches the small intestine. Gall bladder receives the bile secreted from the International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 9 Number 6 (2020) Journal homepage: http://www.ijcmas. com
The effects of feed composition and level on lactational performance in rats and dairy cows : a basic approach to feed description

An investigation into the effects of feed composition on lactational performance was carried out using rats and cows. A graphical representation of the feed as a triangle was used to aid the interpretation of results. The first rat experiment showed that, on high protein feeds, the lactational performance of rats is not depressed when offered feeds of very low carbohydrate content. This was substantiated by the other rat experiments. When carbohydrate in the feed was replaced by fat at low protein content (rat experiment 2) there was a large depression in lactational performance, effectively a cessation of milk production. The interaction between the three feed components protein, carbohydrate, and fat was highly significant. The hypothesis that maternal heat production was limiting food intake was advanced. The third rat experiment used feeds whose composition was marginal in relation to lactational success. The feeds also allowed comparison between feeds of constant nutrient:energy ratio. The results of this experiment indicated that there is an extremely abrupt threshold in feed composition for adequate lactation. This effect could not be attributed to any one nutrient:energy ratio. This experiment also showed the importance of maternal body reserves in support of lactation. A model was developed to explore the hypothesis that maternal heat production was limiting performance, however this model failed. An experiment using sheep was conducted in order to permit prediction of the volatile fatty acid proportions arising from a range of feeds. This experiment was designed to allow application of the rat work to dairy cows. A dairy cow trial was conducted, to compare different feed types and feeding levels. The results of this trial showed no effect of feed type on lactational performance. A linear relationship between food intake and level of milk production was found. This included an effect of feeding level on rate of decline in milk yield. All these findings are discussed in detail.
