POLYMORPHIC LOCI ANALYSIS OF 16 S RIBOSOMAL RNA GENE OF BOMBAY DUCK ( HARPADON NEHEREUS )

Attempts were made to combine morphological and molecular techniques for identification and analysis of evolutionary relationship of commercially important marine lizardfish (Bombay duck) from the Bay of Bengal. For molecular identification, mitochondrial DNA (mtDNA) was extracted using CTAB extraction protocol and 16S rRNA gene was amplified by PCR method. Morphological identification was supported by molecular data generated by 99% identity of BLAST search result of Harpadon nehereus. The nucleotide sequence of H. nehereus was 586 bp long and the G+C content was 51% and intraspecies polymorphic sites were 0.5%. According to interspecies polymorphic sites analysis, 4.9% polymorphism was observed when H. nehereus and H. microchir were compared. Phylogenetic tree was constructed and both the Harpadon spp. formed a monophyletic clade. This analysis will be used to study molecular diversity as well as conservation of this fish species.
Interbreed variation in meiotic recombination rate and distribution in the domestic chicken Gallus gallus

Abstract The efficiency of natural and artificial selection is critically dependent on the recombination rate. However, interbreed and individual variation in recombination rate in poultry remains unknown. Conventional methods of analysis of recombination such as genetic linkage analysis, sperm genotyping and chiasma count at lampbrush chromosomes are expensive and time-consuming. In this study, we analyzed the number and distribution of recombination nodules in spermatocytes of the roosters of six chicken breeds using immunolocalization of key proteins involved in chromosome pairing and recombination. We revealed significant effects of breed (R2=0.17; p<0.001) and individual (R2=0.28; p<0.001) on variation in the number of recombination nodules. Both interbreed and individual variations in recombination rate were almost entirely determined by variation in recombination density on macrochromosomes, because almost all microchromosomes in each breed had one recombination nodule. Despite interbreed differences in the density of recombination nodules, the patterns of their distribution along homologous chromosomes were similar. The breeds examined in this study showed a correspondence between the age of the breed and its recombination rate. Those with high recombination rates (Pervomai, Russian White and Brahma) are relatively young breeds created by crossing several local breeds. The breeds displaying low recombination rate are ancient local breeds: Cochin (Indo-China), Brown Leghorn (Tuscany, Italy) and Russian Crested (the European part of Russia).
Comparative Morphological Evaluation of Different Chilli (Capsicum annuum L.) Varieties of Andhra Pradesh, India for Agronomic Traits

In the present study, 20 chilli cultivars were characterized based on morphology as it serves as discrete identification indicator and also propose to evaluate cultivar diversity for yield related parameters. Among the 20 cultivars, different quantitative and qualitative morphological traits like, hypocotyl pubescence, hypocotyl colour, cotyledon leaf shape, cotyledon leaf colour, cotyledon leaf width and cotyledon leaf length were studied. A stem length to first bifurcation ranged from 10.80 cm (LCA-424) to 26.33 cm (LCA-620) among the 20 cultivars, taller and shorter stems, taller, wider plant, longer and wider leaves were noticed. Hence, this character could be used for varietal identification. Fruit, fruit length, fruit width, pedicel length, dry fruit weight, seed weight and seed size might be efficiently used for different the chilli cultivars. Fruit positions were divided into two groups viz., Pendent and Erect. Among them, maximum number of genotypes had pendent fruits while only one by Mycoteja produced erect fruits. The fruit yield varied from 83.95g to 295.10g with a mean of 146.82g. The maximum mean performance was observed for genotype LCA-625 (295.10 g/plant) followed by LCA-620 (249.93 g/plant) and LCA-424 (244.24 g/plant), while the minimum value was observed for LCA-305 (83.95 g/plant) preceded by LCA-960 (92.77 g/plant). The study has spawned some important morphological traits, which can be efficiently employed in differentiating the chilli cultivars for beneficial agronomic traits.
HOW KNOWLEDGE RECOMBINATION HELP FIRM COPE WITH RADICAL TECHNOLOGICAL CHANGE: COMBINING KNOWLEDGE DOMAINS IN THE PHOTOGRAPHY INDUSTRY

Knowledge recombination may serve as a dynamic capability to cope with radical external change, such as when a new core technology emerges within an industry. We examine how leveraging prior experience in different domains may foster knowledge recombination and positively influence the firm’s technological performance in the domain of the emerging core technology. We specifically consider patents granted within photography in the context of the industry’s 30-year paradigm shift from chemical to digital technology (1974-2004). The results indicate that leveraging prior experience by recombining knowledge from the emerging domain has limited effects on a firm's technological performance; recombining knowledge from unrelated domains is only a slightly better solution; while the best strategy is to recombine complementary knowledge from industry-related domains
THE MONGE PROBLEM IN R: VARIATIONS ON A THEME II

ABSTRACT. In some recent papers [11, 12] it is proved that, under natural assumptions on the first marginal, the Monge problem in the metric space R equipped with a general norm admits a solution. Although the basic idea of the solution is simple the proof involves some very complex technical results. Here we will report a proof of the result in the simpler case of uniformly convex norms. Uniform convexity allow us to reduce the technical burdens while still giving the main ideas of the general proof. The proof of the density of the transport set given in this paper is original.
Inhibition of TLR 4 inhibits allergic responses in murine allergic rhinitis by regulating the NF ‐ κ B pathway

The present study investigated the underlying mechanisms and effects of toll-like receptor 4 (TLR4) on a mouse model of allergic rhinitis (AR). An ovalbumin (OVA)-induced mouse model of AR was treated with TLR4-short hairpin RNA (shRNA). Allergic symptoms were then subsequently assessed. Protein levels of OVA‐specific immunoglobulin E (IgE), eosinophil cation protein (ECP), leukotriene C4 (LTC4) and prostaglandin D2 (PGD2) in mice serum and nasal lavage fluid, as well as various inflammatory cytokine mediators in mice serum, were determined by ELISA. Protein level detection was performed using reverse transcription-quantitative PCR and western blot analysis. The results revealed that TLR4 was highly expressed in the nasal mucosa of AR mice. TLR4 inhibition significantly relieved OVA‐induced AR symptoms. Relief of symptoms was evidenced by a decreased frequency of sneezing and nose friction, reduced levels of OVA‐specific IgE, ECP, LTC4, PGD2, less inflammatory cells and decreased levels of T-helper 2 type cytokines. In addition, the data indicated that OVA-induced activation of the NF-κB pathway was repressed by TLR4-shRNA. The results of the current study indicate that TLR4 may be a promising therapeutic target of AR.
Physiological responses of operators to handle vibration of diesel-fueled single-axle tractor

Hand-arm transmitted vibration originating from a 15 horsepower single-axle tractor can be very strong and cause operator fatigue plus various physiological disorders in vascular, neurological, and musculoskeletal systems. The objective of this work was to measure the characteristics of such hand-transmitted vibrations and its effect on the health of the single-axle tractor operator, in a research program conducted at the Melkasa Agricultural Research Center of Ethiopia. During the study, the measurement of anthropometric data and the heart rate of the operators and vibration at the handle of single axle tractor were conducted. From measured data, the requirement of expenditure energy, physical workload, and operators’ daily vibration exposure was calculated. The average measured resting heart rate, working heart rate and heart rate after the operation was 717, 1624 and 12624 beats/min, respectively. The calculated values of HR reserve (%HRR) or physiological workload and the ratio of working to resting heart rate were 7410% and 2.30.4 (p < 0.0001), respectively. The total energy expenditure of single-axle tractor operators was calculated to be 351.2 kJ/min. The daily exposure m/s2A (8) and total exposure points which were calculated indirectly from measured vibrations at the tractor handle and duration of operation were 12.6 m/s2 and 2520 points, respectively. From measurements of operators’ heart rates, it was concluded that the physical workload fell into the category of extremely heavy work, for which the working heart rate more than doubled the resting heart rate (p < 0.0001). Key words: Tractor vibration, hand-transmitted vibration, single-axle tractor, heart rate, physical workload, vibration exposure.
ECONOMIC GROWTH AND EMPLOYMENT IN AGRICULTURAL SECTOR ON POVERTY IN ACEH PROVINCE Reovasimulo

This empirical study aims to analyze the impact of economic growth and employment in the agricultural sector on poverty in Aceh Province. The study is conducted on annual time series data for the period of 1995-2017 while to explain the research objectives used Autoregressive Distributed Lag (ARDL) model and Granger Causality. The results found, in the short term, only employment in the agricultural sector has a significant effect on poverty. Meanwhile, in the long term, economic growth has a profound and negative impact on poverty. On the contrary, the absorption of labor in the agricultural sector tends to increase poverty. In addition, the results obtained that economic growth has a unidirectional relationship with employment in the agricultural sector. It was, therefore, suggested that the government should prioritize economic development in regions that have relatively high poverty rate and build an agro-industry in Aceh to increase agricultural value added and also absorb more labor so it can enable to reduce the poverty rate.
Anti-Inflammatory Action of Spilanthes acmella : A Systematic Review

Spilanthes acmella known in Brazil as jambu is a typical herb of the northern region of Brazil that has application in traditional medicine to treat toothache, stomatitis and throat diseases, being antiviral, antibacterial, antiseptic, diuretic, anti-inflammatory and healing. Studies included in this systematic review are in vivo experiments using mice whose inflammation was obtained with the use of carrageenan introduced into the paw and the decrease of edema was measured by plethysmometry. There was also, in vitro experiment using murine macrophages. These studies have recognized that Spilanthes acmella has significant anti-inflammatory and analgesic activity. However, additional studies in other models and clinical trials have been recommended to confirm the results and to establish the mechanism of action of the exact as well as the active principles involved in the antiinflammatory and analgesic activity. Although studies investigating the anti-inflammatory effect of Spilanthes acmella are scarce, it is necessary to recognize the biological potential of this species.
Αξιολόγηση της χρήσης τον Precision Xceed ® ως μετρητή της συγκέντρωσης του β-υδροξυβουτυρικοΰ οξέος και της γλυκόζης ολικού αίματος των γαλακτοπαραγωγών αγελάδων

The aim of the study was to evaluate the usefulness of the Precision Xceed® hand-held meter as an on-site method for determining blood ß-hydroxyboutyric acid (BHBA) and glucose concentrations, for the diagnosis of subclinical ketosis in dry and lactating dairy cows. A total of 163 clinically healthy Holstein cows (113 lactating, 8-50 days-in-milk; and 50 dry, 10-40 days pre-partum) from 5 farms located around Thessaloniki region, were blood-sampled once, from the jugular vein of each animal, 5 to 8 hours after the start of morning feeding. BHBA was determined in all 163 cows, whereas glucose only in 114 cows (50 dry and 64 lactating cows). These analyses were performed, for each cow, by both laboratory method (in serum) and Precision Xceed® meter (in whole blood, cowside). Using laboratory serum BHBA concentrations > 1.2 mmol/L as the cut-off point, 11/163 (6.7%) of the tested cows were considered as subclinically ketotic, whereas raising the cut-off to > 1.4 mmol/L, 9/163 (5.5%) cows had subclinical ketosis. All these cows (11 and 9, respectively) were lactating. None of the dry cows had subclinical ketosis at BHBA cut-off of > 1.4 mmol/L. One out of the 50 dry cows (2%) and 15/113 (13.3%) lactating cows sampled were classified as subclinically ketotic when the Precision Xceed® meter was set at BHBA concentrations > 1.2 mmol/L. Overall, mean BHBA and glucose concentrations were not statistically different (P>0.05) between the two methods. Significant positive correlations were found for Correspondence: Panousis N.

Feature Friable Integers : An Overview

A friable (or smooth) integer is an integer without large prime factors. More precisely, let P(n), P−(n) denote respectively the largest and the smallest prime factor of an integer n.1 For y 2, an integer n is said to be y-friable if P(n) y and ysifted if P−(n) > y. The term ‘friable’ reflects the possibility of splitting these integers into small divisors – the small prime factors. When the friable parameter y is very small, these integers can be represented as products of divisors with good size control. This flexibility in the factoring of friable integers is at the origin of several recent breakthroughs in analytic number theory. Another fundamental observation is that every integer n has a unique decomposition of the form n = ab where a is y-friable and b is y-sifted. The structure of the sifted part b resembles that of a prime number while the friable part a is supposed to behave more like a standard integer. This simple idea is often an efficient starting point in the study of sums appearing in analytic number theory problems, as described, for example, in Section 5.1. Research on friable integers really started less than a hundred years ago. Since the 1980s, the theory has been actively developing not only for its own interest, but also for the multiple applications available. Let S (x, y) denote the set of the y-friable integers not exceeding x and let Ψ(x, y) be its cardinality. In the first part of this survey, we provide an account of the various methods developed for estimating Ψ(x, y) according to the relative sizes of x and y and we briefly describe some results related to multiplicative properties of friable integers. Next we depict the role of friable integers in certain factoring algorithms. In the last part, we present various number theoretic-problems for which friable integers led to significant advances. This presentation is far from exhaustive. Our aim is mainly to provide an overview of the role of friable integers in different areas from number theory. One will find more complete presentations in the impressive survey papers of Hildebrand and Tenenbaum [13], Granville [11], Pomerance [17]. We furthermore recommend the book by Crandall and Pomerance [5] and those by Tenenbaum [18,19] which are unavoidable references respectively in algorithmic and analytic number theory. Throughout this text the letter p with or without subscript denotes a prime number and (a, b) is the g.c. d. of the integers a and b. To simplify notation, we write lnk(t) the kth iterated Napierian logarithm of the positive real number t, so that, in particular, for k = 2, ln2 t = ln ln t.
On the Cyclicality of R & D Investments in the Presence of Financial Constraints and R & D Subsidies *

The Schumpeterian view of the business cycle suggests that the opportunity cost of long-term investments, like Research & Development (R&D), is lower during recessions. This implies that firms expand long-term investments in downturns and favor short-run investments in booms. Observing private-sector R&D spending during recent years across the globe, however, does not support this theory. This papers studies the influence of financial frictions and government stimulus on private sector R&D investment over the business cycle. Building on a theoretical model which takes into account the complementarity between R&D and other investments as well as imperfect capital markets and government subsidies, we show that the presence of credit constraints turns R&D more pro-cyclical, while R&D subsidies have the opposite effect. We test the theoretical predictions using firm-level data for Germany for the period 1994 to 2010 and find that without binding credit constraints, R&D investment tends to be counter-cyclical. The more binding the credit constrained, the more pro-cyclical it gets. Moreover, large or subsidized firms' R&D investment is not sensitive to sales shocks while non-subsidized SMEs are most sensitive to the business cycle.
Distribution and characterization of anopheline larval habitats in flooded areas of the Dakar suburbs (Senegal)

Knowledge of mosquito ecology is a prerequisite for efficient implementation of vector control strategies. This one-year study was carried out during the 2013 rainy season and the 2014 dry season throughout the flooded areas of the suburbs of Dakar with the aim to characterize and map anopheline larval habitats. In both seasons, all water bodies that were encountered within the study departments were geo-located and their features (type of water body, size, turbidity and distance to human dwellings) recorded. The presence of anopheline and/or culicine larvae and predators was assessed. A total of 908 and 278 potential larval habitats were visited during the rainy season and the dry season, respectively. A significant positive association was found between the rainy season and the presence of anopheline larval sites, which consisted of ponds, puddles, ravines, drain channels, streams and canals. Anopheline larvae were more likely to be found in clear water bodies located within 10 m to human dwellings. During the dry season, only puddles were likely to host anopheline larvae. Anopheline larval habitats were significantly more frequent in the Department of Rufisque during the rainy season (univariate analysis, P = 0.006) and in the Department of Guediawaye during the dry season (multivariate analysis, P = 0.036). The malaria vector identified was Anopheles arabiensis. Data gathered in this study will guide larval control programmes in urban settings prone to flooding. Key words: Anopheline, larval habitat, flood, suburb of Dakar, Senegal.
Outsourcing information communication technology services in selected public university libraries in Kenya

Outsourcing is a management strategy that is gradually proving its worth in library and information science. The purpose of this study was to investigate the outsourcing of ICT services in selected public university libraries in Kenya in order to establish the challenges facing libraries in outsourcing ICT services. The study adopted a multi-case study strategy in four selected public university libraries in Kenya. Purposive sampling was used to identify respondents. Data collection was done using a semi-structured interview schedule. The findings reveal that public university libraries in Kenya outsource ICT services such as Internet, e-resources and derive benefits such as cost cutting, knowledge and skills acquisition and economies of scale. The study noted that ICT policies and procurement laws are inadequate in guiding the outsourcing processes. The study found that ICT service processes had various challenges such as high cost and loss of control of the services due to relying heavily on the vendors. The study concluded that there was a need for the library management to be conversant with outsourcing procedures, such as negotiation of contracts, to gain more from outsourced ICT services. The study recommended that the university libraries develop, review and implement ICT outsourcing policies. The university management should involve librarians in the outsourcing process and implementation.
Two pathways of how SST anomalies drive the interannual variability of autumnal haze days in the Beijing–Tianjin–Hebei region, China

Abstract. Analogous to the circumstances in wintertime, the increasing severity of autumnal haze pollution over the Beijing–Tianjin–Hebei (BTH) region may also lead to impairment of the socioeconomic development and human health in this region. Despite manmade aerosol emissions, the interannual variability of autumnal (September–October–November) haze days (AHD) in the BTH region (AHDBTH) is apparently tied to the global and regional meteorological anomalies. The present study suggests that an above-normal AHDBTH is closely associated with the simultaneous sea surface temperature (SST) warming in two regions [over the North Atlantic subtropical sector (R1) and over the western North Pacific sector (R2)]. When the autumnal SST warming in R1 and R2 are both remarkably significant, the joint impacts can greatly enhance the likelihood of a higher AHDBTH. Observational and simulation evidence suggests that SST anomalies can affect the variation in AHDBTH via two different pathways. Firstly, SST warming in R1 can induce a downstream mid-latitudinal Rossby wave train, leading to a barotropic high-pressure and subsidence anomaly over the BTH region. Secondly, SST warming in R2 can also result in air subsidence over the BTH region through an anomalous local meridional cell. Through these two distinct pathways, localized meteorological circumstances conducive to a higher AHDBTH (i.e., repressed planetary boundary layer, weak southerly airflow, and warm and moist conditions) can be established.
Barriers that Impede Primary Health Care Physicians ... 3061 Table 3 : Barriers that impede primary health care physicians from screening women for domestic violence at Makkah ALmukarramah city between 2017 and 2018

Background: Nowadays, violence against women represents a major public health concern despite the efforts to raise awareness about it at the local and the global level. Doctors have a crucial role to play in detecting violence against women but they are confronted to many barriers. Objective: To identify the barriers that impede physicians from screening women for domestic violence. Subjects and methods: A cross-sectional study was conducted using a questionnaire to collect data from 62 primary health care physicians at Makah Almukarramah city. Results: More than a half of the physicians, working at primary health centers at Makkah and who participated in our survey, dealt with a case of a women abused by her partner. Many participants agreed that there were barriers that impeded them from screening violence like insufficient training, feeling of embarrassment, shame of asking question about abuse and fear of revenge by the husband or relatives. Conclusion: Implementing training program with intervention could help in managing and preventing violence against women.
