Microbiological Studies on Streptococcus Species Associated with Environmental Mastitis in Sheep and Goats Farms

The current study was carried out on 10 flocks of sheep and goats in Al-Ameria district, Alexandria Province during the period extended from January 2016 till December 2017. A total of 500 milk and environmental samples were collected and examined for isolation and identification of Streptococcus species especially those accused to be a reason for environmental mastitis. The samples were divided into; 300 milk samples of clinically suspected mastitic cases of sheep (150 samples) and goats (150 samples), 100 bedding samples of different sites of yards of sheep (50 samples) and goats (50 samples) particularly those wetted areas with high moisture and organic matter load, finally about 100 representative water samples were collected from water in front of the animals in different sites of yards of sheep (50 samples) and goats (50 samples) by a rate of 10 samples per visit. The obtained results clarified that the total prevalence of Streptococci in the examined samples of sheep and goats farms was 29.20% and 31.20%, respectively. In addition, the prevalence of Streptococci in milk, bedding and water samples was 25.33%, 46%, and 24%, respectively in sheep farms while it recorded 28.67%, 38% and 32%, respectively in goat farms. Biochemical identification of the recovered isolates revealed the presence of Str. agalactiae, Str. dysgalactiae, Str. uberis, Str. canis, Str. faecalis and Str. pyogenes with different rates. Antibiogram test for Str. dysgalactiae and Str. uberis was performed and clarified that Str. dysgalactiae was highly sensitive to Amoxicillin and Erythromycin while it was weak sensitive for Flumequine, Doxycycline and Sulphamethoxazole-Trimethoprim. On the other hand, Str. uberis was found to be quite sensitive to Ciprofloxacin and Amoxicillin while it was resistant to Gentamycin, Flumequine, Enrofloxacin, Doxycycline, Oxytetracycline and Erythromycin. Finally, multiplex PCR was applied for simultaneous detection of Str. dysgalactiae and Str. uberis.
Grid-Based Spatial Index Method for Location-Based Nearest Neighbour Search

—Geo-spatial data becomes more and more large amount of data on the Web. On the other hand, managing massive spatial data is one of challenges for supporting spatial queries and high performance computational is also needed to support spatial queries. Thus there is needed to solve this criteria is to create a better spatial indexing method. The proposed method is to create Grid-based R-tree index structure for k nearest neighbour query and range query. R-tree is constructed with Minimum Bounding Rectangle (MBR) that contains a group of objects. The proposed system is combined R-tree with grid index that is reduced overlapping and covering area. The proposed system is to support spatial queries efficiently and also supports speed up computational performance.
General Ideology of Analysis Digital Medical Images in RGB Format

Methods, technologies and various digital image processing procedures are one of the data analysis tools. At the same time, digital images can be considered as data that belong to the Big Data group. This fully applies to digital color images of cytological preparations. Thus, digital image processing techniques are one of the Big Data analysis tools. A feature of such a tool is the specificity of its use for various types of data, which are presented in the form of digital images. To do this, we examined the problematic aspects of the analysis of cytological specimens of images that are marked in the works of other authors. The paper also examined the issues of complex analysis of color images of cytological preparations. For this analysis, we used the decomposition of the original image into separate color channels, applied the ideology of wavelets to determine areas of interest and a set of morphological operations to specify such areas of interest. These methods are selected taking into account the peculiarities of images of cytological preparations. The results are shown on the example of images of cytological preparations, where megaloblastic anemia cells are also present.
“We need to find a revenue model”: Data journalists’ perceptions on the challenges of practicing data journalism in India

Data journalism is emerging as a new subspecialty in Indian journalism. Indian data journalism practice is in nascent stage and newsrooms have lately started recognizing it as a new practice. There were specific issues and challenges faced by journalists in western news rooms as they adopted the practice. To generate a comparative perspective, the study carried out semi-structured interviews with Indian data journalists about their perceptions on the challenges of practicing data journalism. The results show that there are external and internal bottlenecks in practicing data journalism in India. While irregular data releases, use of unfriendly formats by governmental authorities is a major concern; reluctance of media organizations to invest in data teams is identified as an internal challenge. Indian data journalists are skeptical about the audience’s participatory potential, which has restricted them from relying on practices like crowd-sourcing.
Anthropometric measurements, nutritional status and body composition in children with cystic fibrosis – the prospective study

Background: Cystic fibrosis(CF),despite much progress in therapy, remains the disease which affects nutrition. Nutrition is an important prognostic factor of the outcome of the disease. We want to evaluate physical development, nutrition and body composition in CF children. Material and methods: 75 children diagnosed with CF (9 months to 18 years old) were included into the study. 33 healthy children (9 months to 18 years old) constituted the control group. The study consisted of 2 stages. In the first the differences between groups were investigated. The second, took place a year later. At each time point the following measurements were performed: height, body mass, skin fold, arm circumference; BMI, FFM%, FM% and Frisancho index. FFM (fat free mass), FM (fat mass), muscle mass, TBW (total body water) were evaluated by mans of BIA(bioimpedance). Results: CF children were shorter than healthy children. Stunting affected 18,67% of CF patients at first examination and 21,6% a year later. Underweight was diagnosed in 28% of patients at the beginning and in 41.2% a year after. Underweight was the result of both little FM and scarce muscle mass. Conclusions: Many children with cystic fibrosis suffers from short stature and underweight, which progresses within time. FFM decreases with the disease progress
Lethal attack of Schizotetranychus brevisetosus Ehara (Acari: Tetranychidae) on predatory midge larva

Spider mites (Acari: Tetranychidae) display an anti-predatory strategy by constructing a web using silk threads secreted from the palp tips to distract predators. Several studies have shown the defensive effects of the web itself as well as web-associated ovipositional behaviours (Mori et al. 1999, Oku et al. 2003, Horita et al. 2004, Lemos et al. 2010, Yano 2012). Conversely, alternative behavioural strategies, such as counterattack against predators, have been only reported in Stigmaeopsis spp. (Saito 2010). Stigmaeopsis spp. densely weave nests over depressions on the surface of the host leaves (known as WN species; Saito 1983, 1985), and several generations overlap in the same nest among species that make larger nests. In S. longus (Saito) that live on the Sasa bamboos, adults attending to their offspring increase the survival rate of the offspring by driving out or killing the phytoseiid larvae that enter the nest (Saito 1986, Mori & Saito 2004). Behaviours such as these are also reported in S. miscanthi that inhabit the Chinese silver grass (Saito et al. 2011, Yano et al. 2011) and S. nanjingensis (Ma and Yuan) that reside on the Moso bamboo (Saito & Zhang 2017). One possible factor allowing the evolution of this somewhat risky behaviour in these species is the high genetic relatedness among the nest members in the colony. This relatedness is because the individuals develop in the same nest where they were born and end up mating with their siblings or even their
DEVELOPMENT OF A RAILROAD TRACK INSPECTION SYSTEM BASED ON VISUAL PERCEPTION USING LABVIEW

Railroad track inspection is essential to guarantee safe operation condition for the rails to travel on. Even though railway sector invests hefty costs, time and strong human workforce to ensure the performance and safety of the railroads, frequent accident occurs throughout the year due to poor visual inspection carried out by the human inspectors. The quality of inspection remains a question mark and deteriorates progressively when the experienced human inspectors are made to carry out the inspection all along the railroads exposing them to mental fatigue and other potential health hazards. Therefore, in this study, a simple method using visual perception and image processing techniques for the inspection of railroad track for anomalies is presented as an alternate solution to the traditional inspection system. An automated wheeled mobile robot is also prototyped to carry out the inspection on the railroads. This prototyped system uses a visual perception algorithm based on edge detection and feature extraction is developed in LabVIEW, which continuously records the images of the track; assesses and detects the railroad components such as loose bolts, bent boltsand surface cracks, which are very critical for rail safety. The performance of the proposed system is investigated in the laboratory conditions and results show high performance in the detection of railroad track anomalies.
Estrus Induction by Hormonal and Nutritional Approaches in Canines

The dogs are non-seasonal monoestrous animals. Most of the breeds having one breeding cycle in a season. Normally bitches attain puberty at an age of 6-14 months and there starts first estrous cycle. Each estrous cycle is divided into four phases such as proestrus, estrus, diestrus and anestrus. Different signs are observed during each phase related to clinical, hormonal, behaviour, physiological ad cytological changes in canines.
Approximate Joint Diagonalization for ARMA Dependent Source Separation

In this paper, an Approximate Joint Diagonalization (AJD) approach is proposed to separate dependent source signals. The diagonal structure of the Auto Regressive Moving Average (ARMA) matrix coefficients moves the problem from Blind Source Separation (BSS) to AJD one. The identified matrix coefficients of the observed signal are jointly diagonalized to achieve the mixture matrix identification. Simulation results are provided to illustrate the effectiveness of the proposed approach.
Evaluation of Gamification in E-Learning Systems for Elementary School Students

Gamification is often proposed as a promising solution to traditional e-learning systems by the incorporation of game elements and mechanisms to enhance the motivation, engagement and students’ learning. However, most current studies lack careful and thorough experimental evaluation on the effect of gamification and are normally applied to science learning for adults which makes it difficult to generalize the findings to other learning domains. This paper addresses this issue by offering a controlled experiment with 58 elementary school students studying a course on Arabic language to investigate the learning effect of gamification. The results indicate that gamification positively enhances the learning outcome and students’ learning motivation.
The Effects of COVID-19 Pandemic on Oil Prices, CO 2 Emissions and the Stock Market: Evidence from a VAR Model

This paper examines the impact of COVID-19 pandemic on oil prices, CO2 emissions and stock market volatility over the period January 22, 2020 – March 30, 2020 using an unrestricted VAR. We demonstrate that although the increasing number of COVID-19 infections causeda decrease in the price of crude oil, the negative response of the oil market is short-lived.However, the response of economic activities as measured by CO2 emissions to a shock on COVID-19 infections is negative throughout the forecast period. Also, we find that the current situation created by COVID-19 led appears to have had a stronger impact on equity market volatility than on crude oil prices and CO2 emissions. Lastly, we find that the share of forecast error variance in the level of CO2 emissions is stronger than that of the energy and stock markets. Taken together, our findings shed light on the need for economic intervention to speed up recovery and boost investor’ perception of long-term growth.
Artificial Intelligence-based Modeling of Interfacial Tension for Carbon Dioxide Storage

A key variable for determining carbon dioxide (CO2) storage capacity in sub-surface reservoirs is the interfacial tension (IFT) between formation water (brine) and injected gas. Establishing efficient and precise models for estimating CO2 – brine IFT from measurements of independent variables is essential. This is the case, because laboratory techniques for determining IFT are time-consuming, costly and require complex interpretation methods. For the datasets used in the current study, correlation coefficients between the input variables and measured IFT suggests that CO2 density and pressure are the most influential variables, whereas brine density is the least influential. Six artificial neural network configurations are developed and evaluated to determine their relative accuracy in predicting CO2 – brine IFT. Three models involve multilayer perceptron (MLP) tuned with Levenberg-Marquardt, Bayesian regularization and scaled conjugate gradient back-propagation algorithms, respectively. Three models involve the radial basis function (RBF) trained with particle swarm optimization, differential evolution and farmland fertility optimization algorithms, respectively. The six models all generate CO2 – brine IFT predictions with high accuracy (RMSE
Testing the Bidirectional Relationship Between Reading and Writing Skills

Reading and writing have an essential place in the social life of individuals as well as in school learning. In this study, the bidirectional relationships between reading and writing skills were examined after gender and socioeconomic level of students were controlled. The participants of this research are 5th grade 240 students from ten primary schools in four different districts of Ankara in Turkey. A text has been chosen to evaluate students’ comprehension and writing skills and a test that includes questions related to the text has been developed. In order to evaluate the reading and writing skills of the students, the analytic and holistic rubrics were used. Hierarchical multiple linear regression analysis was conducted to reveal the bidirectional relationship between reading and writing skills. Results indicate that reading and writing skills are important predictors of each other and support the possibility of a bidirectional relationship between the two. One possible explanation of this is that reading and writing skill influence each other. Researchers, practitioners, and parents may need to target both reading and writing skill to best help poor readers become proficient.
Hibiscus sabdariffa Aqueous Leaf Extract Reverses Hematological Alterations in Phenylhydrazine Anemic Wistar Rats

Background: The extract of Hibiscus sabdariffa commonly known as Sobo is widely consumed for its nutritional and health benefits. This study investigated the effect of aqueous leaf extract of H. sabdariffa on anemic condition caused by phenylhydrazine in rats. Materials and Methods: Thirty (30) rats used for this study were divided into three groups of 10 rats each. Group 1 received distilled water and served as control. Group 2 received phenylhydrazine (40 mg/kg, i.p.). Group 3 was treated with phenylhydrazine (40 mg/kg, i.p.) 30 minutes prior to administration of (200 mg/kg, p.o.) aqueous extract of H. sabdariffa (Sobo) once daily for 14 days. At the end, 2 ml blood samples were collected through cardiac puncture into clean sample bottles containing ethylenediamine tetra acetic acid (EDTA) for hematological analyses. Results: Sobo significantly increased (P<0.05) hemoglobin (Hb) concentration and packed cell volume (PCV) in the phenylhdrazine-treated rats. Also, Sobo significantly (P<0.05) increased total white blood cell (TWBC) in phenylhydrazine administered rats. However, the extract did not produce any significant effect on mean corpuscular hemoglobin concentration (MCHC) relative to control and anemic groups. Conclusion: The findings from this study revealed that the aqueous extract of H. sabdariffa demonstrates anti-anemic effect in rats treated with phenylhydrazine, suggesting its ethno-pharmacological beneficial effect in anemic conditions.
A Comparative Study of Semen Characteristics and Testosterone Concentration in Ram Breeds of Saudi Arabia

The goal of this study was to evaluate and compare the semen characteristics, and testosterone concentration for three breeds raised under hot, desert conditions in Saudi Arabia. A total of 150 rams (Najdi, Naemi, and Harri) were used, aged 12, 18, 24, 30 and 36 months (ten rams from each breed in each age group). Body weight and testicular parameters were measured. In addition, testosterone concentration (TC), ejaculate volume (EV), sperm concentration (SC), total sperm output per ejaculate (TSO), live sperm percentage (LSP), sperm progressive motility (SPM) and sperm mass motility (SMM). The results show that TC and EV differed significantly (P less than 0.01) between breeds. At 36 months, semen characteristics (TSO, SMM and SPM) differed significantly among breeds. Naemi rams were superior to Najdi and Harri in terms of the mean live sperm percentage (LSP) for all age groups. These results may assist in ram selection for breeding programs based on high reproductive performance.
Biodiversity conservation effectiveness provided by a protection status in temperate forest

: The establishment and maintenance of protected areas is the backbone of global 15 conservation strategies to halt biodiversity loss. However, despite the more than 200,000 legally 16 designated protected sites worldwide, the rate of species extinction has not decreased, for which 17 some debate the real effectiveness of protected areas to preserve biodiversity. Using data from 18 tropical areas, many studies have attempted to test the effectiveness of protected areas by 19 comparing species richness in protected and neighbouring unprotected sites, without reaching a 20 consensus. Here, we extend this line of research with data from temperate deciduous forests 21 occurring inside and outside Picos de Europa National Park and Biosphere Reserve (NW Spain). 22 Specifically we compare data from Mixed broadleaved woodlands, Beech forests ( Fagus sylvatica 23 L.) and Pyrenean oak ( Quercus pyrenaica Willd.) forests. We conducted botanical inventories and 24 recorded ecological data from 25 0.2-ha concentric plots distributed in forest commons inside the 25 reserve and from other 25 similar plots established in neighbouring not protected forest commons. 26 Data were evaluated using modelling methods and used to construct a set of ecological indicators.
The physiological butyrylcholinesterase tetramer is a dimer of dimers stabilized by a superhelical assembly

The quaternary structures of the cholinesterases, acetylcholinesterase (AChE) and butyrylcholinesterase (BChE), are essential for their localisation and function. Of practical importance, BChE is a promising therapeutic candidate for intoxication by organophosphate nerve agents and insecticides, and for detoxification of addictive substances. Efficacy of the recombinant enzyme hinges on its having a long circulatory half-life; this, in turn, depends strongly on its ability to tetramerize. Here, we used cryo-electron microscopy (cryo-EM) to determine the structure of the highly glycosylated native BChE tetramer purified from human plasma at 5.7 Å. Our structure reveals that the BChE tetramer is organised as a staggered dimer of dimers. Tetramerization is mediated by assembly of the C-terminal tryptophan amphiphilic tetramerization (WAT) helices from each subunit as a superhelical assembly around a central anti-parallel polyproline II helix (PRAD). The catalytic domains within a dimer are asymmetrically linked to the WAT/PRAD. In the resulting arrangement, the tetramerization domain is largely shielded by the catalytic domains, which may contribute to the stability of the HuBChE tetramer. Our cryo-EM structure reveals the basis for assembly of the physiological tetramers, and has implications for the therapeutic applications of HuBChE. This mode of tetramerization is seen only in the cholinesterases, and may provide a promising template for designing other proteins with improved circulatory residence times.
Taxonomic note on a rare fish infecting freshwater mould Achlya ambisexualis Raper 1939 (Achlyaceae) isolated from Chandraprabha dam, Uttar Pradesh, India

Achlya spp. are oomycetous water moulds, responsible for freshwater fish diseases causing great economic losses. An Achlya sp. implicated in significant fungal infections of both live and dead fish as well as their eggs, has been isolated from the water and soil samples collected from Chandraprabha dam (Chandauli District, Uttar Pradesh, India) employing standard baiting method. Based on morphological characterisation, the strain was identified as Achlya ambisexualis Raper 1939 (Saprolegniales, Oomycetes). It is a dioecious species, characterised by the presence of an achlyoid type of spore dehiscence from both primary and secondary sporangia, differentiated by its oospheres predominantly maturing into eccentric oospores, generally 1-18 per oogonium and gemmae cylindrical in both antheridial and oogonial mycelia. In India, this species was recorded from a single collection in the past but lack proper description and illustrations. The present study describes and illustrates this species for the first time in India and hoped to be beneficial for ichthyopathologists and researchers as A. ambisexualis is known as a necrotroph or parasite of fishes and their eggs.

Transmit Beampattern Design for Dual-Function Radar-Communication System with an Interleaved Array

In this paper, a beampattern design method is proposed for the multi-input-multi-output (MIMO) dual-function radar-communication (DFRC) system with an interleaved array. To make full use of the whole aperture, first, the transmit array is partitioned into two interleaved subarrays, one is for radar and the other is for downlink communications. Then, both the radar waveform and communication beamformers are optimized by combining the null-space projection (NSP) method and cyclic approach (CA) to perform the coexistence of MIMO radar and downlink communications. Besides, the communication beampattern can be utilized to improve the detection performance. Finally, several numerical results are given to show the effectiveness of the proposed method.
