Genetic variation within and among three ostrich breeds, estimated by using microsatellite markers

Genetic diversity within and among three ostrich populations was investigated to corroborate whether these populations can be classified genetically as three different breeds. The DNA of South African Black (SAB, n = 30), Zimbabwean Blue (ZB, n = 32) and Kenyan Redneck (KR, n = 17) birds was assessed for genetic differences using 19 microsatellite loci. The number of alleles, as well as observed and expected heterozygosity of alleles, was determined. Genetic differentiation was measured using the F-statistic (FST) and Nei’s genetic distance. Significant differences were observed among the three breeds. The SAB and ZB (FST = 0.10 and Nei = 0.49) were genetically more similar, whereas the genetic distance between the KR and ZB breeds was the greatest (FST= 0.13 and Nei = 0.61). The SAB strain exhibited the greatest observed heterozygosity (Ho = 0.72) within its population while the ZB and the KR exhibited lower levels of heterozygosity (Ho = 0.68). Based on these results, it was suggested that crossbreeding between these breeds would lead to heterosis in commercial ostrich enterprises. Keywords: Breed, genetic differentiation, heterosis, heterozygosity
The relationship between facebook attachment and obsessive-compulsive disorder severity

Despite the widespread use of social networking sites (SNS) such as Facebook, an adequate understanding of their impact on the users’ mental health is still lacking. The present study intends to expand on the current understanding of the linkage between social networking site use and mental health. Our study explored how Facebook use may be associated with obsessive-compulsive disorder (OCD), with the inclusion of obsessive-compulsive beliefs as a mediator. One hundred and fifty-six undergraduate students completed the questionnaire given. Overall, Facebook use contributed to OCD severity through obsessive-compulsive beliefs as the mediator. The present study also yielded other relevant results for cyberpsychology that may help pave the way for future studies.

Nitrogen level affects growth and reactive oxygen scavenging of fenugreek irrigated with wastewater

Today, due to the constraint in availability of the freshwater for irrigation, wastewater is being used for irrigation of agriculture fields. Wastewater contain plant nutrients that favour crop growth but leave a burden of heavy metals which can enter the food chain and is a cause of great concern. This research work aimed at evaluating the potential utilization of wastewater as an alternative source of water and nitrogen (N) for fenugreek. For this purpose, a pot experiment was conducted with wastewater and four doses of nitrogen (0, 20, 40 and 60 kg.ha) to observe a comparative effect on growth and biochemical characteristics using fenugreek as the test crop. Wastewater and soil used in the experiment were analyzed for their physicochemical properties. Results indicate that wastewater was richer in essential plant nutrients but contained some heavy metals in amounts well below the permissible limits for its use as irrigation water. Use of wastewater with 20 kg.N. ha improved growth, proline and antioxidant enzymes of the plant as compared to application of groundwater with no fertilizer. Lipid peroxidation increased with wastewater but decreased with the increasing nitrogen doses, so the best combination (WW×N20) has negative impact on this parameter. These results concluded that wastewater can efficiently substitute groundwater and also works as a nutrient source whereas application of nitrogen could provide protection against the oxidative stress by increasing the antioxidant protective system.
Variants of PGIS and PPARÃÂ³ in Idiopathic Pulmonary Arterial Hypertension

Introduction: Idiopathic Pulmonary Arterial Hypertension (IPAH) is a subset of a heterogeneous group of diseases called Pulmonary Arterial Hypertension (PAH), characterized by elevated pulmonary arterial pressure (PAP) and is associated with severe arteriopathy, vascular lesions, and right heart failure. The role of prostacyclin synthase, an enzyme responsible for production of prostacyclin, and peroxisome proliferator-activated receptor gamma, involved in many cellular activities, is studied here. Objectives: The objective of the study is to determine any association of prostacyclin synthase and Peroxisome proliferator-activated receptor gamma with Idiopathic Pulmonary Arterial Hypertension Materials and methods: A total of 77 IPAH patients and 100 controls were genotyped using PCR SSCP and RFLP, and appropriate statistical tests were employed to determine the significance and to interpret the results. Results and conclusion: This study has attempted to correlate promoter/gene polymorphisms of PGIS to its activity, and it can be concluded that the VNTR polymorphism and the polymorphism found in exon 6 may not have an effect on the levels of PGIS. The alanine variant of P12A polymorphism of PPARγ was found to be significantly associated with a reduced risk of IPAH.
Diaspores and related hydroxides: Spectral‐compositional properties and implications for Mars

Differences in spectral reflectance properties (0.3–26 μm) of a suite of metal hydroxides (gibbsite, bohmite, diaspore, goethite, and manganite) have been found to be a function of both structural and compositional differences between these minerals. The properties of the O-H stretching fundamental bands in particular can be used to identify the presence of these minerals and to discriminate isostructural and heteromorphous species. This is due to the fact that the O-H stretching fundamental bands are very intense in these minerals and occur at longer wavelengths than those of other minerals, and also due to the fact that these metal hydroxides lack strong absorption bands at shorter wavelengths. In the case of dimorphous minerals such as bohmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), differences in the wavelength positions of O-H stretching fundamental bands can be of the order of 0.1–0.3 μm. Reflectance spectra of metal hydroxide-bearing “ores” (bauxites) and impure samples indicate that accessory phases, in particular iron-bearing minerals, have a more pronounced effect on spectral reflectance toward shorter wavelengths. Intimate mixtures of diaspore + orthopyroxene indicate that diaspore abundances as low as 5 wt% (or less) can be detected by the appearance of characteristic absorption bands at 3.33 and 3.41 μm. This finding has particular relevance to the study of near-infrared spectra of Mars, in that the conditions which favor diaspore formation on the Earth may have also been prevalent early in Mars' history. If diaspore did form on Mars in the past, it is likely to have persisted to the present.
Trends in populations of elephant and other large herbivores in Gonarezhou National Park, Zimbabwe, as revealed by sample aerial surveys

For 30 years, regular aerial surveys in Zimbabwean protected areas were funded, designed and executed primarily to estimate elephant numbers. Other large herbivores were recorded, even though some species were not easily seen from the air in savannah woodlands. Population estimates for species other than elephant provided indices of abundance that could be used to determine temporal trends in population size. This study tests for significant trends in the abundance of large herbivores in Gonarezhou National Park, assuming that data from aerial sample surveys designed for elephant also provide accurate estimates of real trends in the populations of other herbivores. For each species, the exponential rate of population change was calculated using weighted regression, with the variance of this rate based on the sampling variances of the population estimates. Significant population trends were detected for eight species. Before the 1992 drought, elephant number was held approximately constant by frequent culls, but afterwards, it increased at a mean annual rate of 6.2% (confidence limits 4.0% and 8.6%). Elephants in cow herds increased at 7.3%, significantly faster than elephants in bull herds (−0.5%). Buffalo, eland, kudu, nyala, waterbuck, wildebeest and zebra all increased in number, after population declines during the drought. Resume Pendant 30 ans, les etudes aeriennes faites au Zimbabwe ont ete financees, concues et realisees avant tout pour estimer le nombre d'elephants. D'autres grands herbivores ont aussi ete notes, meme si certaines especes n'etaient pas faciles a detecter d'en haut dans les forets de savane. Les estimations de populations pour des especes autres que l'elephant ont donne des indices d'abondance qui pourraient servir a determiner les tendances de la taille des populations dans le temps. Cette etude recherche des tendances significatives de l'abondance des grands herbivores du Parc National de Gonarezhou, en posant l'hypothese que les etudes d'echantillonnage aeriens concues pour des elephants donnent aussi des estimations correctes des tendances reelles des populations d'autres herbivores. Pour chaque espece, le taux exponentiel de changement de population fut calcule en utilisant une regression ponderee, la variance de ce taux etant basee sur les variances d'echantillonnage des estimations de population. Des tendances de population significatives furent detectees pour huit especes. Avant la secheresse de 1992, le nombre d'elephants etait garde a peu pres constant grâce a de frequents abattages, mais ensuite il a augmente a un taux annuel moyen de 6,2% (limites de confiance : 4,0% et 8,6%). Le nombre d'elephants des groupes de femelles a augmente de 7,3%, significativement plus vite que dans les groupes de mâles (- 0,5%). Les nombres de buffles, elands, kudus, nyalas, waterbucks, gnous et zebres ont tous augmente apres les declins de population observes pendant la secheresse.
What Sort of Role Do Management Information Systems Undertake in Strategy Practice? A Case Study Investigation in Tourism Sector

In attempt to understand how management information systems play role on strategy implementation, the study uses a case study of one branch of an internationally well-known Hotel Chain. The findings show that management information systems has an impact on the strategy implemention process in terms of contributing to develop specific procedures regarding decision making process, accelerating the decision process through providing true and fast information to the managers, and helping them to maket he right decisions. The emprical evidence from the case study also suggests that management information systems play an important role in strategy implementation enabling very important information to reach into relavant parts of the organisation in a systematic way.
Efficient Data Mining Method to Localise Errors in RFID Data

Since the emergence of Radio Frequency Identi? cation technology (RFID), the community has been promised a cost effective and ef? cient means to identify and track large number of items with relative ease. Unfortunately, due to the unreliable nature of the passive architecture, the RFID revolution has been reduced to a fraction of intended audience due to the anomalies. These anomalies are duplicate, positive and negative readings. While duplicate readings and wrong data (false positive) can be easily identi? ed and recti? ed, that is not the case for false negative or missed readings. To identify missed readings data mining methods can be used. However, due to its vast volume and complex spatio-temporal structure of RFID data, traditional data mining methods are not necessarily directly applicable. In this paper we propose method to identify possible missed RFID readings by applying association rules data mining method. In empirical study we show that our algorithm is accurate and ef? cient and also we show that it scales well with increased number of rows therefore it is applicable on vast volume on spatio-temporal RFID data.
Community-Managed Water Supply Systems in Rural Uganda: The Role of Participation and Capacity Development

Over 85% of Uganda’s 34 million people depend on rural water supply systems and the current water and environment sector performance report (2017) reports an 84% functionality of rural water sources such as boreholes and shallow wells with a hand pump. Ensuring the continued operation of water points, and in keeping with participatory theory, the water user’s committees (WUCs) should also be a vehicle for empowering communities while bringing about greater equity of use. However, WUC members do not acquire the knowledge and skills they need by default but require different types of training. This study sought to evaluate community participation and capacity development in WUCs in relation to community-managed water supply systems. A shared dialogue workshop (SDW), as well as 642 randomly selected households across 17 villages in two Parishes in Lwengo district, southern Uganda were considered. Results indicated that 41.7% of surveyed households used an unprotected source while up to 30% had a member in a WUC. Fifty-two percent of households had never made any financial contributions to a WUC, while 34.6% did so on an ad hoc basis. This paper examines the relationship between participation, mobilization, and financial contributions. The chi-square test indicated mobilization has no impact on household financial contributions to a WUC. However, the majority of even those households that were mobilized made a payment only occasionally, and specifically when the source broke down. Additionally, the test result reveals that there is no difference between better off and relatively poor households in their contributions to a WUC, an indication that other factors influence such decisions. Training activities, especially on the operation and maintenance of water points and to undertake minor repairs, were mostly provided by non-governmental organizations (NGOs)/project staff. Abandoned boreholes, lack of rehabilitation activities, and loss of enthusiasm are all indications that the technical, financial, and institutional performance of community-managed water supply systems needs improvement.
Silibinin, up-regulates chemokine receptor expression in MDA-MB-231 breast cancer cell line

Introduction: Silibinin, a polyphenolic flavonoid isolated from the milk thistle plant (Silybummarianum), has various applications in cancer therapy. This investigation aimed to examine the effects of silibinin on proliferation and chemokine receptor expression on MDA-MB-231 cells, a highly metastatic human breast cancer cell line. Methods: The cytotoxic effect of silibinin on MDA-MB-231 cells was determined by micro-culture tetrazolium test (MTT) assay. In addition, the expression of chemokine receptors CXCR3, CCR5 and CCR7 genes in response to silibinin was evaluated by Real-Time PCR. Results: Data analysis from MTT assay showed that silibinin had dose-dependent and time-dependent inhibitory effects on MDA-MB-231 cell line. Moreover, Real-Time PCR analysis showed that silibinin not only had no inhibitory effects on CXCR3, CCR5 and CCR7 gene expressions, but also could increase significantly the expression of these genes in a dose and time-dependent manner. Conclusion: These results revealed for the first time the increased possibility of CXCR3, CCR5 and CCR7 genes expression in response to silibinin in human breast cancer cells.

Effect of oxygen adsorption on the local properties of epitaxial graphene on SiC (0001)

The effect of oxygen adsorption on the local structure and electronic properties of monolayer graphene grown on SiC (0001) has been studied by means of low-energy electron microscopy (LEEM), microprobe low-energy electron diffraction (μLEED), and microprobe angle resolved photoemission (μARPES). We show that the buffer layer of epitaxial graphene on SiC (0001) is partially decoupled after oxidation. The monitoring of the oxidation process demonstrates that the oxygen saturates the Si dangling bonds, breaks some Si–C bonds at the interface, and intercalates the graphene layer. Accurate control over the oxidation parameters enables us to tune the charge density modulation in the layer.
Analysis of caesarean section in a tertiary care hospital, Assam, India

Background: One of the commonest surgery performed worldwide is caesarean Section (CS). The World Health Organization (WHO) has identified an ideal caesarean section (CS) rate for a nation of around 10-15%. In recent times the proportion of delivery conducted by caesarean section has increased. Methods: This is a retrospective study of all the caesarean deliveries performed between 1 January 2010 to 31 December 2018 in the Department of Obstetrics and Gynaecology in Silchar Medical College. The caesarean rate was calculated as: (total number of caesarean deliveries/ total number of deliveries) × 100. The indications for CS included foetal distress, malpresentation, previous caesarean section, multiple gestation, failed induction, failed progression, cephalopelvic disproportion, maternal indications, obstetric indication and foetal indications. Results: During the study period a total of 75685 patients delivered. 25805 patients had undergone CS with the CS rate being around 34.1%. Majority of the CS (75.6%) were performed as emergency procedure. Maximum number of patients were between 21-30 years (73.24%) and 54.47% were primipara. Majority of the patients (68.37%) belonged to the rural areas. Foetal distress (32.8%) was the commonest indication followed by post caesarean pregnancy (26.76%). Conclusions: The rate of caesarean section is increasing with time. As primary caesarean section usually determines the lady’s future obstetric course, it is of prime importance to give effort for safe reduction of caesarean. Individualization of the indication and careful evaluation, following standardized guidelines and practice of evidencedbased obstetrics followed by audits in the institution, can help us limit the caesarean rates.
Optimization of Clostridium acetobutylicum metabolism for biobutanol production using in silico tools

Alternative biofuels to petroleum-derived compounds are in high demand nowadays. Ethanol has played an important role in the picture as the major biofuel currently produced [1], [2]. However, advances in technology and the current search for alternatives biofuels, brought butanol into the scenario. The characteristics of this primary alcohol make it an interesting alternative to ethanol as it can directly replace gasoline without the need of engine adaptation. Moreover, it is an excellent diluent and solvent for manufacturing intermediates of chemical industry augmenting the potential of this compound. With the most recent Genome-scale Model (GEM) of C. acetobutylicum available, new in silico strategies can be further explored to improve butanol production. By modeling clostridial metabolism, new insights on the acidogenic-solventogenic metabolism are debated in this work.
Calculation Methods for Gasket Plate Heat Exchangers Used in Vegetable Oil Manufacture Comparative study

Gasket plate heat exchangers are extensively used in the vegetable oil manufacture, due to their robust construction and effective heat transfer. Knowledge of heat transfer coefficients is useful in dimensioning of new industrial plants or in technological analysis of the actual installations. The aim of this work was to find the best mathematical equations in literature for the calculation of heat transfer coefficients in the gasket plate heat exchanger equipped with 30° chevron angle plates. For this, experimental coefficients were determined in an industrial plant processing sunflower oil and then compared with values obtained by calculation with mathematical equations from literature. The best fitting was with Kumar model.
Active faulting induced by slip partitioning in Montserrat and link with volcanic activity: New insights from the 2009 GWADASEIS marine cruise data

New high‐resolution marine data acquired aboard R/V Le Suroît was used to map active normal faults offshore Montserrat in greater detail. The main faults of the Montserrat‐Havers fault zone have cumulative scarps up to 200 m high, and offset sedimentary layers by hundreds of meters. They are arranged in a right‐stepping, en echelon, trans‐tensional array, which confirms that they accommodate the left‐lateral component of motion resulting from slip partitioning of oblique convergence along the volcanic arc. They cut across Montserrat's recent volcanic complex. Faulting and fissuring exerted control on the position of andesitic domes, which are aligned along the N110°E average fault trend. The ≈10 km‐long fault segments that cross the island could produce damaging, M ≈ 6 events comparable to the shallow, 16 March 1985, Mw∼6.3 earthquake that ruptured a submarine, N140°E striking, left‐lateral fault near Redonda.
2D Burgers equation with large Reynolds number using POD/DEIM and calibration

Model order reduction of the two‐dimensional Burgers equation is investigated. The mathematical formulation of POD/discrete empirical interpolation method (DEIM)‐reduced order model (ROM) is derived based on the Galerkin projection and DEIM from the existing high fidelity‐implicit finite‐difference full model. For validation, we numerically compared the POD ROM, POD/DEIM, and the full model in two cases of Re = 100 and Re = 1000, respectively. We found that the POD/DEIM ROM leads to a speed‐up of CPU time by a factor of O(10). The computational stability of POD/DEIM ROM is maintained by means of a careful selection of POD modes and the DEIM interpolation points. The solution of POD/DEIM in the case of Re = 1000 has an accuracy with error O(10−3) versus O(10−4) in the case of Re = 100 when compared with the high fidelity model. For this turbulent flow, a closure model consisting of a Tikhonov regularization is carried out in order to recover the missing information and is developed to account for the small‐scale dissipation effect of the truncated POD modes. It is shown that the computational results of this calibrated ROM exhibit considerable agreement with the high fidelity model, which implies the efficiency of the closure model used.
