Published: January 2020

Mongolia has been exposed to extreme draught and dry summer for its historical development due to geographical location, climatic condition, surface characteristics and being subject to vulnerable and dry region in terms of ecological system. Besides it, rapid increase in the minerals production has been causing heavy metal pollution in soil, water and plants. Soil pollution is main parameter of environmental pollution and air and water pollution directly depend on it. Main influencing factor of endemic diseases of livestock is chemical ingredient of soil, water and plant. Due to negligent use and disposal of lead containing sources including acid and alkali batteries with lead conductor, vehicle accumulators in last years, environment has been polluted greatly and it becomes the cause of animal poisoning. Heavy metals are dangerous because of their persistence and toxicity. Soil behaves as a sink of heavy metals by aerial deposition of particles emitted by human activities. The aims of this work were to identify the levels of lead in accumulator processing plant and city areas and animals. We have determined lead level in biological samples /livestock blood/ using total reflection X-ray fluorescence spectrometer and compared the results found by the Lead Care II.

To deepen understandings on changes in mare milk yield and composition along with lactation,  physico-chemical characteristics and freshness of raw mare milk this study was conducted. The first  trial on the change in mare milk yield and composition was conducted along with different lactation  period using 7 adult mares. Milk yield was determined volumetrically after 2 hour foal separation.  Hand milking with milk ejection by foal was applied. Milk yield reached at peak in August which  corresponds to around 90th days of lactation. Lactose content reaches its max value at 90th day of  lactation also and it remains as high as its peak until the milking season ends while the yield was  decreased significantly (p≤0.05). Fat and protein contents were gradually decreased to the end of  milking season. To conduct quality evaluation of raw mare milk it is vitally important to know  physico-chemical characteristics. To clarify did this second trial in comparison with cow milk.  Results were indicated that pH value is higher in mare milk and acidity and viscosity is lower in mare  milk than those in cow milk. A hygienically obtained mare milk samples were used in this experiment.  Acidity, pH and Total Bacterial Counts were monitored with the reference to raw horse milk standard  of Mongolia. The results were indicated that hygienically obtained mare milk can be kept for 12 hours  at room temp. In case of refrigerated condition it kept its acceptable freshness up 10 days of storage.

Study on realtionship between seed germination and antioxidant enzyme activity
Authors: J Bayarmaa , D Purev
Published: January 2020

Success in plant cultivation is related to seed production and germination. Seed germination and seedlings are well-regulated process which involves high metabolic activity and production of reactive oxygen species (ROS) in cell. However, plant POS defense network, composed of antioxidant enzymes and antioxidants are responsible for maintaining ROS levels under control. In plant cells, antioxidant enzymes as superoxide dismutase (SOD), peroxidase (POD), catalase (CAT) and others protect cells from oxidative damage during germination and growth.  Thus, in this work we studied the content of soluble protein and the activity of enzymes as catalase, peroxidase, polythenol oxidase (PPO) and superoxide dismutase in two cultivars of wheat, barley and oat seeds differing in germination and year of harvesting.  The results showed that the activities of antioxidant enzymes and seed germination are directly dependent and this relation clearly seen for catalase and peroxidase activity.

The inhibitive action of (-)-(S)-9-fluoro-2,3-dihydro-3-methyl-10-(4-methyl-1-piperazinyl)-7-oxo-7H-pyrido[1,2,3-de]-1,4-benzoxazine-6-carboxylic acid (Levaquin) on API 5L X-52 steel in 2 M HCl solution was investigated using potentiodynamic polarization method and quantum chemical study. Levaquin drug showed good inhibition efficiency of 88 and 95 % at 303 and 323 K, respectively. The results of experimental measurements revealed that Levaquin drug works as a mixed type inhibitor. Langmuir thermodynamic model was tested to describe the mode of inhibitor adsorption on the steel surface. The quantum chemical calculations confirmed the efficacy of Levaquin drug as a corrosion inhibitor.
Electrolytic iron production from alkaline suspensions of solid oxides: compared cases of hematite, iron ore and iron-rich Bayer process residues

Published: January 2020

Iron can be produced by the direct electrochemical reduction of hematite particles suspended in hot, concentrated NaOH solutions. Because various other iron sources can be considered, the present work was aimed at investigating the electrolytic treatment of the “red mud” generated by the Bayer process for alumina preparation from bauxite. Such sources contain very high amounts of impurities, in particular silicon and aluminium oxide-based minerals, in addition to other mineral phases. Electrolytic reductive treatment of the industrial red mud sample was shown to be possible but with both lower current density and current efficiency than for pure hematite. After deposition tests at a fixed current density, further experiments in simulation tests have been carried out for better understanding. In particular, hematite particles were tested with and without impurities introduced in the solution. Presence of little soluble impurities at the particle surface appear to hinder the reactivity of the suspended particles at the cathode surface, whereas side-hydrogen reaction still occurs.
From a Lifeboat Ethic to Anthropocenean Sensibilities
Authors: Tuana Nancy ,   International Association for Environmental Philosophy
Published: January 2020

To claim that “humans have become a geological agent,” to worry that “humans are interrupting, refashioning, and accelerating natural processes” is to reinforce metaphysical divides—humans and nature, the cultural and the natural. It is furthermore to reinforce all the narratives from which these divides are animated: modernity, colonialization, enlightenment with their attendant discourses of progress, control, and purity. In its place I advocate Anthropocenean sensibilities. Sensibilities in which our attentiveness to influences and exchanges becomes heightened, where we learn to live in the midst of change, with a new responsiveness to uncertainties that render not-knowing animating rather than paralyzing.
Indigenous Peoples and Climate Change

Published: January 2020

In this essay, we will discuss the lessons that we have learned in a course titled “Indigenous Peoples and Climate Change” regarding Indigenous efforts and epistemologies to cope with stresses and plights induced by global climate change. Primarily informed by humanistic perspectives, we examine how Indigenous peoples, especially those of North America, process climate change through their cultural values and social priorities, with a particular focus on human emotions or feelings associated with their homeland, which often called sense of place or belonging, in contrast to the abstract concepts that originate from the natural sciences.

A NEW IDENTIFICATION METHOD OF THE TRANSFORMER INRUSH CURRENT BASED ON IMPROVED HILBERT-HUANG TRANSFORM ALGORITHM
Authors: WU NA , FAN SHUXIAN , LIU LIN , GAO YAN , WEI AYING
Published: January 2020

As the main form of protection for transformers, differential protection requires correct operation because it directly influences the safe operation of transformers. Meanwhile, transformer inrush current is an important factor in the tendency of transformers to malfunction. To accurately and reliably discriminate inrush current from internal fault current, this study proposed a novel method based on the Hilbert–Huang transform (HHT) algorithm. We integrated the empirical mode decomposition (EMD) algorithm with the permutation entropy (PE) algorithm and put forward a new algorithm named modified ensemble EMD. First, the original current signal was added to an opposite white noise signal with several repetitions for the EMD. Next, PE was employed to detect the decomposition results, where the noise, intermittent, and high-frequency signals with relatively large entropies were removed from the original signal. The remainder of the signal was decomposed by the second EMD to obtain a group of approximately stationary intrinsic mode munction (IMF) signals. Finally, the first IMF signal was extracted for HHT to obtain an instantaneous frequency, and the transformer inrush current and internal fault current were accurately identified by the time intervals between two adjacent catastrophe points in the instantaneous frequency. Results demonstrated that the time intervals between two adjacent catastrophe points in the instantaneous frequency of the transformer inrush current were less than 14 ms and that of various internal faults (i.e., turn-to-turn, single-phase, phase-to-phase, and three-phase faults) were approximately 20 ms. Results indicate that the inrush current and internal fault current are correctly, reliably, and quickly identified by the time intervals between two adjacent catastrophe points in the instantaneous frequency. The time intervals of the catastrophe points in the instantaneous frequency of the inrush current under different closing initial phase angles (0°, 30°, …, 330°) are less than 12.5 ms, indicating that the method is unaffected by the dead angle of the inrush current, closing initial phase angle, and non-periodic components. The proposed method provides references for identifying inrush current with regard to transformer differential protection.

Blended Learning er en fleksibel tilrettelæggelsesform, der integrerer forskellige former for asynkron interaktion, hvor de studerende tilegner sig det faglige indhold uafhængigt af fælles tid og rum. Fleksible læringsrum appellerer til voksne studerende i et efter- og videreuddannelsesforløb, hvor der ofte er en række individuelle behov at tage hensyn til som følge af den voksnes  familie- og arbejdsliv. I denne artikel præsenteres og diskuteres resultaterne af en undersøgelse , der pågik i efter- og videreuddannelsen på University College Nordjylland i efteråret 2018, hvor 45 diplomstuderende deltog i afprøvning af et blended learning-læringsdesign. Formålet med undersøgelsen var at identificere, hvad der har betydning for voksne diplomstuderende, når de er tilmeldt et uddannelsesforløb tilrettelagt som blended learning. Undersøgelsen har identificeret fire forskellige profiler af blendede learnere i et efter- og videreuddannelsesforløb. De fire profiler afspejler en variation i forhold til deltagernes motivation for både læring og for blended learning. Derudover viser profilerne en stor variation i deltagernes læringstilgang samt de læringsforudsætninger og de læringserfaringer, de bringer med ind i mødet med et blended uddannelsesforløb. Undersøgelsens resultater danner udgangspunkt for videreudvikling af blended learning på diplomuddannelserne med læringsdesign, der sigter mod en højere grad af fleksibilitet og individualiserede læringsrum.
New legal realism
Authors: Gruzdev Vladimir Sergeevich
Published: January 2020

The subject of the study is one of the actively developing trends in Western legal thought over the past two decades, especially American, which is called "new legal realism" and positions itself both as a special variant of the "organizational paradigm of interdisciplinary research" and as a progressive empirical doctrine of law that overcomes the shortcomings of "traditional approaches to law".. The program of this direction is based on the idea of the possibility of effectively solving the problems of classical American legal realism by updating, first of all, the methodology of legal research. The study critically analyzes not only the content of the main ideas of the "new legal realists", but also an attempt to articulate the well-known developments of their predecessors, especially European ones, as a "new" direction in legal science. The methodology of the research is based on such methods of working with the ideas of foreign authors as the study of original texts, program statements (materials of conferences, symposiums and speeches), tracing the connection of past and modern teachings, analysis of involvement in the discussion of traditional issues and topics of legal issues. The conclusions of the essentially critical analysis of the content of the ideas of "new legal realism" are as follows: a narrowly focused behavioristic analysis of judicial activity with the pathos of the scale of the tasks being solved creates a paradox of the absence of a problem of law (even in the sense of classical realists) in the "new" legal doctrine; the methodology of "new realists" in the form of interdisciplinary practices and orientation to the analysis of "big arrays of data" is not something new, remaining within the framework of sociological approaches to law; manipulation of traditional legal issues leads to the reproduction and distortion of the ideas of predecessors.

Authors: Movahed Ali , Ghalehteimouri Kamran Jafarpour
Published: January 2020

Cities are important tourist destinations and tourism has affected the urban environment. Urban tourism space is where tourism resources are located. The behavioural pattern of tourists also subordinates of tourism resources. Therefore, behavioural geography explains the spatial patterns of the behaviour of tourists as a cognitive-perceptual process. The behavioural school has attended to areas such as mental maps of behaviour, spatial behaviour of tourism, and perception of the environment. The main objective of this research is identifying the spatial behaviour of tourists in Tehran. The research method is descriptive-analytic and used secondary data, which are available in different reports, drafts, and related institutes and questionnaire to collect the research data. The research results show that the behaviour pattern of foreign tourists depends on tourism resources. These tourism resources are located in the central part of Tehran. In addition, the south entrance of the city (Imam Khomeini airport) is the most important entrances for foreign tourists and transporting pattern is from the south to the centre and north of Tehran. Since Tehran city has located between ways so stopping time is short in this city. In other words, visiting the city's attractions has focused on the type of historical-cultural tourism in the central part of Tehran.

This study was aimed at evaluating on-station performance of indigenous breeds of cattle for milk yield and body conformation traits. The data for the study came from four hundred and fifty (450) genotypes (Bunaji, Friesian X Bunaji and Gudali) of cattle reared on-station from 1995 through 2012. Morphometric variables measured were BW: Body weight (Kg); BL: Body Length (cm); HW: Height at withers (cm); CW: Chest width (cm); HG: Heart Girth (cm); Rumwi: Rump width (cm); TL: Teat Length (cm); RUH: Rear Udder Height (cm); UC: Udder Circumference (cm); TY: Total Yield (Litres). There variations in morphometric traits and milk yield among the genotypes of cows. Bodyweight was significant and highly correlated with total yield in milk for all the genotypes of cows. The accuracy of predicting total yield in milk using morphometric traits was best in FriesianXBunaji (76.24%) followed by Bunaji (70.43%) while Gudali had the least prediction classification (62.06%). It is concluded that performance differences among the indigenous cattle indicate genetic diversity exists among the genotypes.

Authors: Dhir Bhavya , Singla Neerja
Published: January 2020

Background: The present study was aimed to review the consumption pattern and health implications of convenience foods in regular life. The term 'Convenience food' is being widely used in the catering industry due to rapid progress in food technology. Consumption of convenience foods is inexorable in modern scenarios due to rapid urbanization, changing lifestyle, rising purchasing power and adaptation to western culture.

Methods: A constructive review work was done from available data sources and available literatures.

Results: The Indian ‘Ready-to-Eat (RTE)’ market reached at Rs 2900 crore and Rs 3500 crore in 2015 and 2016 respectively. RTE foods are growing at 40% per year. According to the World Health Organization, the trend towards surplus convenience foods provides the food  industry with various commercial opportunities and profitable outcome for the food manufacturers. However, these foods are regarded as one of the least healthy dietary options, contributing to the health and diet-related diseases comparable to the risks associated with smoking, alcohol and drugs.

Conclusion: Excessive consumption of convenience foods is one of the major factors for the higher incidence of obesity and other non-communicable diseases.

Authors: Manasseh E. A.
Published: January 2020

The objective of this study was to determine the effect of tillage and water management on the physical stability of irrigated lowland rice field, in Kwalkwalawa, Sokoto State. The experiment was carried out in a farmer`s field, near the Usmanu Danfodiyo University Teaching and Research Farm, Kwalkwalawa, Sokoto State. The coordinates of the area were taken using global positioning system (GPS) model Garmin etrex 20.0, which shows that the area is located on (N13°05.963”E005°12.650” and at 252 m asl). The soils of the study area were classified as Aeric Endoaquepts at subgroup level in the USDA Soil Taxonomy System which correlated with Gleyic Cambisols in the World Reference Base. The treatments consisted of factorial combination of two tillage systems (conventional tillage (CT) and reduced tillage (RT), three irrigation water managements (Alternate one, two and three days irrigation intervals, which were carried out from one week after transplanting to hard dough stage) and three rice varieties (FARO 44, 60 and 61) all laid in a split-plot design and replicated three times. After harvest, disturbed soil samples were collected with the aid of soil auger, prepared and passed through 5 mm sieve for aggregate stability determination. Result reveals that a consistent trend in aggregate size fraction was observed between the two tillage systems in both years, were a significant decrease in values of aggregate fractions of both the CT and RT in 2019 compared to in 2018. Aggregate size fraction of 5-2 mm had a significantly high value of RT compared to CT, 2-0.25 mm fractions were at par (0.41) while a greater value of aggregate fractions for CT in both 0.25-0.005 mm and ˂0.005 mm were observed compared to RT. Alternate days to irrigation and sampling depths increase with a corresponding in all the aggregate size classes in the two years of this study. A significant difference in mean weight diameter (MWD) and geometric mean diameter (GMD) between the two tillage, water management and depth was noticed in both years of the trial where RT and alternate one day had high value while MWD and GMD increase with increasing depth.

Published: January 2020

Drought is a serious bottleneck in the production of rice globally. For this, an experiment was conducted in-vitro on six rice genotypes viz. BRRI Dhan-28, Begunbahar, Burikatari, Pashpai, Dular and Begunbichi to investigate the effect polyethylene glycol (PEG) mediated artificial drought on morpho-physiological parameters such as germination percentage, shoot length, root length, fresh weight, dry weight, turgid weight, relative water content and proline accumulation. Here, different doses of PEG-6000 viz. 0gL-1, 15gL-1, 30gL-1, 45gL-1 and 60gL-1 were used with Murashige and Skoog (MS) medium. The results demonstrated that BRRI Dhan-28, Burikatari and Dular revealed greater performance at control conditions but at the highest degree of water stress conditions only Burikatari showed higher mean value for all parameters studied. Again, Begunbichi followed by BRRI Dhan-28 exhibited the lowest mean value for almost all traits except for proline accumulation. Here, water stress decreased the performance of morpho-physiological characters except proline accumulation in rice. The cluster analysis was performed and distributed into three groups where there was a significant variation among the clusters at different water stress conditions. Here, the genotype Burikatari is more diverse giving maximum Euclidian distances in drought treatments. It could be considered as a parent in the hybridization program against Begunbahar, Dular and Paspai. Therefore, considering the mean performances and cluster analysis, Burikatari exhibited greater performances against the highest degree of drought conditions. This genotype may bear drought-tolerant gene for which could be utilized for further development of drought-tolerant variety and gene transfer.

Published: January 2020

Many researches have been going on since last two decades for object recognition, shape matching, and pattern recognition in the field of computer vision. Face recognition is one of the important issues in object recognition and computer vision. Many face image datasets, related competitions, and evaluation programs have encouraged innovation, producing more powerful facial recognition technology with promising results. In recent years, we have witnessed tremendous improvements in face recognition performance from complex deep neural network architectures trained on millions of face images. Face recognition is the most important biometric and stills many challenges such as pose variation, illumination variation, etc. In order to achieve the desired performance when deploying in reality, the methods depend on many factors. One of the main factors is quality of input image. Therefore, facial recognition systems is installed outdoors which are always affected by extreme weather events such as haze, fog. The existence of haze dramatically degrades the visibility of outdoor images captured in inclement weather and affects many high-level computer vision tasks such as detection and recognition system. In this paper, we propose a preprocessing method to remove haze from input images that enhances their quality to improve effectiveness and recognition rate for face identification based on Convolutional Neural Network (CNN) based on the available datasets and our self-built data. To perform the proposed method for outdoor face recognition system, we have improved the system accuracy from 90.53% to 98.14%. The results show that the proposed method improves the quality of the image with other traditional methods.

Enteric fever remains a major disease burden in developing countries. Paratyphoid fever has been described as a less severe infection than typhoid fever. Salmonella serovar Paratyphi A has been however seen as an increasing problem in many areas in Asia and can cause a disease with severity proportional to that of Salmonella serovar Typhi.

Among Asian countries China, India, Indonesia, Pakistan, and Vietnam are considered to be endemic for typhoid.

This case describes female infant presenting with long standing lymphadenopathy in the cervical and axillary area. Considering the duration of clinical feature she was investigated for Tuberculosis and Hodgkins lymphoma. The extensive course of investigations ruled out both. Sampling of gastric aspirate in pursuit of diagnosing tuberculosis incidentally revealed Salmonella Paratyphi B repeatedly as the cause of the generalized lymphadenopathy.This is a first report which describes such a case in the best of our knowledge.

Authors: Khater Enas Sh. , Abdo Khalid H. M.
Published: January 2020

Background: All health care facilities should intensify TB screening and encourage treatment of latent tuberculosis infection (LTBI) among Healthcare workers (HCWs) to prevent progression to tuberculosis (TB) disease.

Aim: This study was conducted to determine the prevalence and associated risk factors of LTBI among HCWs in Al Quwayiyah General hospital as well as to compare the performance of QuantiFERON-TB Gold Plus (QFT-Plus) to TST in identifying LTBI.

Methods: A cross sectional study and prospective cohort study was performed from January to July 2019 in Al Quwayiyah General hospital involving a total of 718 HCWs. questionnaire with socio-demographic data and work history was filled, and both tests were done TST and QFT test for each Healthcare worker.

Results: The study showed that The prevalence of latent tuberculosis diagnosed was 9.05% and 9.19% using QFT-Plus and TST respectively. Only 26 (3.62%) subjects were positive for both tests whereas 131 (18.25%) were positive by either test. Comparing the results of the QFT-Plus with those of the TST, both tests had a significant total agreement of 88.8. Negative concordance comprised 85.37% of the results, and positive concordance comprised 3.62%. However, positive TST but negative QFT-Plus comprised 5.57% of the results, and negative TST but positive QFT-Plus comprised 5.43%. The association between risk factors and QFT-Plus test results in the studied groups showed that the smoking, health status, immunosuppresion, housing, occupation, contact T.B. at work place, past history of TB and diabetes mellitus appear as significant risk factors. The association between the studied risk factors and TST in the studied groups showed sig­nificant difference noted for smoking, BCG vaccination, immunosuppresion, housing, occupation, contact T.B. at work place, past history of TB and diabetes mellitus.

Conclusion: The prevalence of latent tuberculosis diagnosed was 9.05% and 9.19% using QFT-Plus and TST respectively. Testing of HCWs at hire and periodically can help in the detection of LTBI Large scale study is recommended to confirm such findings in Saudi Arabia, also the use of Quantiferon for detection of LTBI beside using TST is recommended as it reduce the false positive reports by TST and is not affected by prior BCG status.
