3D Printed Al2O3 for Terahertz Technology

In this work we demonstrate that 3D printed Al<sub>2</sub>O<sub>3</sub> is a promising material for prototyping and precise fabrication of quasi-optical devices in the terahertz frequency range. The 3D printed Al<sub>2</sub>O<sub>3</sub> exhibits a low absorption coefficient (<inline-formula> <tex-math notation="LaTeX">$\alpha < 2\textrm {cm}^{-1}$ </tex-math></inline-formula>at 1 THz) and a high refractive index (<inline-formula> <tex-math notation="LaTeX">$n >3$ </tex-math></inline-formula>). The printing resolution in the sub <inline-formula> <tex-math notation="LaTeX">$50~\mu \text{m}$ </tex-math></inline-formula> range allows for the implementation of structures in the 0.3-3.0 THz range on the subwavelength scale. Furthermore, the printing process enables the realization of crystalline solids, which allows the use of the Al<sub>2</sub>O<sub>3</sub> birefringence effect. Here, a <inline-formula> <tex-math notation="LaTeX">$\Delta n \approx ~0.05$ </tex-math></inline-formula> was achieved and used for the implementation of <inline-formula> <tex-math notation="LaTeX">$\lambda $ </tex-math></inline-formula>/2-wave plates working at ~1 THz. The material properties and wave plates were characterized using a terahertz time-domain spectrometer.

Sexual Dimorphism in A Cross River Ecotype Local Chicken – Rose Comb (Gallus gallus domesticus)

ABSTRACT---Sexual dimorphism in the local chicken (Gallus gallus domesticus)-Rose Combin Cross River was investigated. Sixty (60) male and female Gallus gallus domesticus chickens were evaluated for the effect of sex on body weight (BW), body length (BL), body girth (BG), thigh length(TL), shank length (SL) and keel length (KL) which were measured fortnightly for twelve (12) weeks. Sexual Size Dimorphism Index (SSDI) and Sexual Dimorphism Index (SDI) were used to confirm relative contribution of each trait to total dimorphism. The values obtained for SSDI and SDI respectively were 1.61 and 61% for BW; 1.26 and 26.52% for TL; 1.23 and 23.81% for SL; 1.22 and 21.50% for BL; 1.18 and 18.20% for BG; 1.17 and 17.94% for KL. To identify the best trait for predicting sex, stepwise discriminate analysis was employed and the Wilk’s Lamda values obtained were BW(0.471); TL(0.452); SL(0.401); BL(0.283); BG(0.272) and KL(0.271). Results showed that there were significant (p<0.05) differences in all measured parameters at week 6 with mean BW, BL, BG, SL, KL and TL of 300.01 and 253.24; 22 and 18.62; 5.20 and 3.98; 4.60 and 3.50; 5.50 and 3.90; 13.10 and 11.20 for both male and female birds respectively. These results indicate that sexual dimorphism is exhibited in all morphometric traits in favor of the male with BW as the highest dimorphic trait.
Assessment of ICT Skills Relevant for Effective Learning Possessed by Undergraduate Students at University of Nigeria

This study examined the information and communication technology (ICT) skills relevant for effective learning possessed by undergraduate students. The study made use of descriptive survey research design. The study participants were 320 undergraduate students of university of Nigeria. The instrument used for data collection was “Relevant ICT Skills for Effective Learning among Undergraduate Students Questionnaire” (RISELUSQ). The reliability of the instrument was determined using Cronbach-Alpha method and a reliability coefficient of 0.84 was obtained. Four research questions and two hypotheses guided the study. The data collected were subjected to analysis, the mean and standard deviation were used to answer the research questions while the hypotheses were tested using t-test and ANOVA at 0.05 level of significance. The findings revealed that undergraduate students possessed the relevant ICT skills that will enhance their learning and that the ICT skills of the male students were not different from that of the female. The findings also showed that the ICT skills of undergraduate students differ based on their educational level, particularly, between the 100 level and 500 levels. Equally, the finding reveals that the students face some ICT challenges like non-functional/limited projectors in classrooms, limited e-learning facilities among others. Based on the findings, it was recommended that students be encouraged to continue to improve on their ICT skills as it will enable them strive well academically and that school authorities should ensure adequate and proper infrastructures/ICT facilities be put in place within the university environment.
‘Give me my pathway!‘: multinational migration, transnational skills regimes and migrant subjectification

In this article, I address the interplay between migration regimes and migrant subjectivities in stepwise multinational migration through a comparative analysis of biographical interviews with migrants in the healthcare and dairy farm work sectors in New Zealand. In both sectors, migrants’ trajectories involve movements from Asia to locations in the Middle East, North Africa or Japan before arrival in New Zealand, and in some cases plans for onward migration. The analysis of these migration patterns and the narratives of migrants, reveal an emergent transnational skills regime that involves connected but uncoordinated systems of skills recognition; negotiating this regime occurs through increased attunement to migration on the part of multinational migrants, as well as adaptation to the expectations of authorities and employers. I conclude the article by suggesting that while multinational migration involves new opportunities for people on the move it also entails greater entanglement in the unequal conditioning of transnational migration.
Asymmetrical relationship between oil prices, gold prices, exchange rate, and stock prices during global financial crisis 2008: Evidence from Pakistan

Abstract The study investigated that whether the relationship between macroeconomic fluctuations and stock indexes is symmetrical or asymmetrical in nature. This study employed nonlinear autoregressive distributed lag models for the times before and after 2008 economic crises. The overall sample period contains 168 observations between January 2004 and December 2018. The period between January 2004 and December 2007 was considered as pre-economic crisis period containing 48 observations whereas, period between January 2008 and December 2018 was considered as post-economic crisis containing 120 observations. Four different types of unit root tests, i.e., augmented Dickey Fuller test, Philips Perron test, Zivot-Andrew unit root, and Kwiatkowski Philips Schmidt Shin test have been employed to find out the stationarity in data. Findings suggested that in the long run and before global financial crisis, investors react differently to gold prices and oil prices. In long run and after crisis, investors have shown different reactions to all macroeconomic fluctuations. This showed that after crisis, investors reacted differently to positive and negative shocks of gold prices, exchange rate, and interest rate. Another interesting aspect that after global financial crisis, investors reacted only to positive shocks of gold prices, interest rates, and exchange rate in long run. This research contributes to existing literature by identifying that relationship between macroeconomic fluctuation and stock prices is asymmetric in nature whereas, in previous researches authors have assumed linearity in the time series data. The asymmetric effect of macroeconomic variables on stock prices should be considered for investors, governments, and other stakeholders during investment decisions.
Demand for Safe Spaces: Avoiding Harassment and Stigma

What are the costs to women of harassment on public transit? This study randomizes the price of a women-reserved "safe space" in Rio de Janeiro and crowdsource information on 22,000 rides. Women in the public space experience harassment once a week. A fifth of riders are willing to forgo 20 percent of the fare to ride in the "safe space" . Randomly assigning riders to the "safe space" reduces physical harassment by 50 percent, implying a cost of $1.45 per incident. Implicit Association Tests show that women face a stigma for riding in the public space that may outweigh the benefits of the safe space.
Effect of Terminal Drought Stress on Morpho-physiological Traits of Wheat Genotypes

Development of wheat varieties with low moisture requirements and their ability to withstandmoisture stress may cope-up well with the on-coming peril of drought conditions. Ten wheat genotypesincluding two new strains, PBGST-3, Hero, Bhittai, Marvi, Inqlab, Sarsabz, Abadgar, Kiran, Khirman andPBGST-4 were sown in split plot design with factorial arrangement in four replications at ExperimentalField, Department of Plant Breeding & Genetics, Sindh Agricutlure University, Pakistan during 2012-13.The results revealed that water stress caused significant reductions in all morpho-physiological traits. Thegenotypes differed significantly for all the yield and physiological traits. The interaction of treatments ×genotypes were also significant for all the traits except plant height, productive tillers/plant, grains/spikeand harvest index, were non-significant which indicated that cultivars responded variably over the stress treatments suggesting that breeders can select the promising genotypes for both stress and non-stressenvironments. Among the genotypes evaluated Bhittai, Kiran-95, PBGST-3 and Sarsabz showed goodperformance as minimum reductions occurred under terminal stress conditions for all the traits studied.Hence, above mentioned genotypes were considered as drought tolerant group. The high positive correlationsof physiological traits like chlorophyll content and relative water content with almost all yield traits indicatedthat these physiological traits could serve as reliable criteria for breeding drought tolerance in wheat. Thenegative correlations of electrolyte leakage with several important yield traits indicated that though thisphysiological trait has adverse effect on yield attributes, yet it could reliably be used to distinguish betweendrought tolerant and susceptible wheat genotypes.
Applications of Bone Histology in Tracking Exploitation Markers: From the Site Inamgaon, Maharashtra

: Bone Histology, particularly the study of osteon morphology and morphometry is used extensively by palaeontologists to reconstruct pre-mortem conditions in large vertebrates. The skeletal system is dynamic and undergoes modification throughout an animal’s life cycle in response to various physical and environmental stimuli, most notably in the remodelling and reconfiguration of skeletal tissue at the microscopic level. The size, shape and distribution of osteons in the long bones of a vertebrate animal have often been proved to reflect various changes engineered by adverse environmental conditions. The present work assumes that the exploitation of domestic animals - especially when carried out intensively over a relatively short period - can engender similar changes in the osteon microstructures of these animals through activity such as herd migration, fattening, confinement and so on. Taking the Late Jorwe phase at the Deccan Chalcolithic site of Inamgaon as a case study, the present work carries out a histological examination of bone samples of Sheep ( Ovis aries ) and Goat ( Capra hircus ), which were intensively exploited at the site during this period. The shape, frequency and configuration of osteons (and other histological features) are recorded and correlated with the different phases of exploitation in order to determine their effect on the skeletal tissues.
Acidophilic biodesulphurization of calcined pet coke and coal samples in iron and iron-free leaching media

Mineralogically distinct coal samples respond differently to microbial attack. In the present study, a mixed meso-acidophilic bacterial consortium predominantly comprising of Acidithiobacillus ferrooxidans strain was investigated for its biodesulphurization abilities for three distinct sulphur bearing samples (Goa CPC, Rajasthan Lignite, Assam Coal) of Indian origin in iron (9K+) and iron-free (9K−) media. A media devoid of Fe (II) iron was more effective for sulphur removal with maximum desulphurization of 45.19% for Assam coal followed by 36.8% for Rajasthan Lignite and 23.38% for CPC respectively. The proximate analysis, FTIR patterns and XRD analysis of the samples provided better insights into understanding the mineralogical and compositional changes in the coal matrix. Owing to the higher efficiency, Assam coal was additionally subjected to further optimization studies and characterization of the treated coal through TGA. The study indicated that the gross calorific values for all the samples increased following microbial treatment in 9K− media thereby providing a scope for further scale-up studies.
Intricate structure of the interphase chromocenter revealed by the analysis of a factor involved in species formation

In higher eukaryotes centromeres often coalesce into a large intranuclear domain called the chromocenter. Chromocenters are important for the organization of pericentric heterochromatin and a disturbance of their formation results in an upregulation of repetitive elements and causes defects in chromosome segregation. Mutations in the gene encoding for the centromere associated Drosophila speciation factor HMR show very similar phenotypes suggesting a role of HMR in chromocenter architecture and function. We performed confocal and super resolution microscopy as well as proximity based biotinylation experiments of HMR and its associated protein HP1a to generate a molecular map of HMR and HP1a bound chromatin. Our work reveals an intricate internal structure of the centromeric chromatin region, which suggests a role of HMR in separating heterochromatin from centromeric chromatin.
Unconventional Magnetism in Layered Transition Metal Dichalcogenides

In this contribution to the MDPI Condensed Matter issue in Honor of Nobel Laureate Professor K.A. Müller I review recent experimental progress on magnetism of semiconducting transition metal dichalcogenides (TMDs) from the local-magnetic probe point of view such as muon-spin rotation and discuss prospects for the creation of unique new device concepts with these materials. TMDs are the prominent class of layered materials, that exhibit a vast range of interesting properties including unconventional semiconducting, optical, and transport behavior originating from valley splitting. Until recently, this family has been missing one crucial member: magnetic semiconductor. The situation has changed over the past few years with the discovery of layered semiconducting magnetic crystals, for example CrI 3 and VI 2 . We have also very recently discovered unconventional magnetism in semiconducting Mo-based TMD systems 2H-MoTe 2 and 2H-MoSe 2 [Guguchia et. al., Science Advances 2018, 4(12)]. Moreover, we also show the evidence for the involvement of magnetism in semiconducting tungsten diselenide 2H-WSe 2 . These results open a path to studying the interplay of 2D physics, semiconducting properties and magnetism in TMDs. It also opens up a host of new opportunities to obtain tunable magnetic semiconductors, forming the basis for spintronics.
Effect of Different Ratio Omega-3 and Omega-6 in Total Mix Ration on Productive Performance, Blood Metabolites and Estrous Characteristic of Ewes

This study was conducted to compare the effect of different ratio of omega-3:omega-6 in total mix ration to blood metabolites and reproductive performance of ewes. A total of 25 young ewes were randomly assigned to five experimental groups and five replications : R0 (without omega-3:omega-6), R1 (omega-3:omega-6 1:8), R2 (omega-3:omega-6 1:6), R3 (omega-3:omega-6 1:3), R4 (omega-3:omega-6 1:2). The parameters measured were feed intake, productive performance, blood glucose and cholesterol pre-mating period. Parameters of characteristic estrous measured were onset of estrous, length of estrous and estrous response. The result showed that ratio of omega-3 and omega-6 1:2 have a greatest daily weight gain and feed efficiency. Ratio of omega-3 and omega-6 1:2 have blood glucose lowest, but highest blood cholesterol. Addition of omega-3 cause to delays onset of estrous. The conclusion is greatest length of estrous, estrous response and pregnacy rate on ratio of omega-3 and omega-6 1:2 in ration.
Distrust in corporate communications: does it matter?

PurposeThis study provides much needed empirical data to conceptualise organisational distrust in communications' scholarship. A limited understanding of distrust has implications for corporate communication scholars and practitioners as, ultimately, efforts to rebuild trust and reduce distrust in organisations and corporations may be hindered if we do not truly understand the complexity and nature of the concepts we are trying to repair.Design/methodology/approachA repeated single-criterion card-sort method was utilised in this study to allow the sample of 40 respondents to identify the terms they associate with organisational trust and distrust.FindingsFrom the current study's findings, it is proposed that there is support for organisational distrust to be considered and studied as a separate and distinct concept to organisational trust within the corporate communications and public relations literature. The current study's findings do not neatly reflect all the items included in existing scales for organisational distrust, and accordingly this suggests that further research into distrust as a concept is warranted.Originality/valueThis study contributes to the literature by presenting a proposed conceptualisation of organisational distrust and providing further evidence for organisational distrust and organisational trust to be studied as related but separate concepts. Developing a more comprehensive conceptualisation of organisational trust and distrust is important for both communication scholars and practitioners as it allows for a more accurate understanding of relationship quality between stakeholders and organisations.

SYNTHESIS AND COMPLETE NMR SPECTRAL ASSIGNMENTS OF NEW BENZYLAMINO COUMARIN DERIVATIVE

This research involves the reaction of 4-chloro-3-nitrocoumarin and (4-methoxyphenyl)methanamine, whereby a novel coumarin derivative 4-[(4-methoxybenzyl) amino]-3-nitro-2H-chromen-2-one was obtained in good yield. The reaction was carried out in ethyl acetate, in the presence of triethylamine. Also, a detailed spectral analysis of a new coumarin derivative is presented. Resonance assignment was achieved using one- (1H NMR and 13C NMR) and two-dimensional NMR techniques (1H-1H-COSY, NOESY, HSQC, and HMBC). The NOESY correlations of protons from arylamino substituent and coumarin core indicate their spatial orientation.
Production of Chips from Logging Residues and Their Quality for Energy: A Review of European Literature

Wood chips from logging residues are a renewable solid fuel that has become widely used in the energy sector. The current work presents a review of European papers on various aspects of wood chips production published in the years 2005–2018. The effects of the comminution method on the quality and energy parameters of the resulting wood chips were analysed. Most authors identified terrain and roadside chipping as the optimum technologies from the energy viewpoint. Furthermore, seasonal changes in the moisture content of wood chips have implications for their ash content and calorific value and determine the annual patterns of supplies to energy plants. In general, logging residues should be chipped approximately five to seven months after harvesting and delivered over economically feasible distances, which have increased in recent years due to the large dispersion of forest areas and energy plants. In a number of cases, logging residue chips did not meet the quality specifications contained in the relevant ISO standards, which may result in technological problems with their burning, especially in small to medium energy plants.
BIOSYNTHESIS AND CHARACTERIZATION OF SILVER NANOPARTICLES FROM MARINE MACROSCOPIC RED SEAWEED HALYMENIA PORPHYROIDES BOERGESEN (CRYPTON) AND ITS ANTIFUNGAL EFFICACY AGAINST DERMATOPHYTIC AND NON-DERMATOPHYTIC FUNGI

Objective: The current study illustrates the biosynthesis of economically scalable and energy efficient colloidal silver nanoparticles (AgNPs) from marine red seaweed Halymenia porphyroides Boergesen (Crypton) collected from Southeast coast of Tamil Nadu, India, and their antifungal efficacy against dermatophytic and non-dermatophytic fungi was evaluated. Methods: The biosynthesis of silver nanoparticles from marine macroscopic red seaweed H. porphyroides Boergesen were synthesized by green synthesis method and characterized by UV–Vis spectroscopy, Fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction, thermogravimetric analysis (TGA), scanning electron microscope (SEM), and transmission electron microscopy (TEM). The efficacy of silver nanoparticles against dermatophytic and non-dermatophytic fungi was performed by disk diffusion method. Results: The presence of silver nanoparticles with an average size between 34.3 and 80 nm and exhibiting face-centered cubic structure was confirmed. SEM revealed the morphology of the nanoparticles as spherical and TEM exhibited the nanoparticle distribution. The FT-IR spectra confirmed the presence of potential biomolecules in the seaweed crude extract which is responsible for reducing and capping the bioreduced silver nanoparticles. The UV absorption spectra at 430.5 nm revealed the characteristic spectra of the silver nanoparticles. The purity and the thermal stability of silver nanoparticles were revealed by TGA. Silver nanoparticles showed significant efficacy against dermatophytes and Rhizopus microsporus among non-dermatophytes. Conclusion: Intermediate efficacy was observed against dermatophytes and among non-dermatophytic fungi R. microsporus exhibited better efficacy, whereas Aspergillus flavus were resistant to the biosynthesized silver nanoparticle.
