Published: December 2020

We introduce a new R package ‘MrIML’ (Multi-response Interpretable
Machine Learning). MrIML provides a powerful and interpretable framework
that enables users to harness recent advances in machine learning to map
multi-locus genomic relationships, to identify loci of interest for
future landscape genetics studies and to gain new insights into
adaptation across environmental gradients. Relationships between genetic
change and environment are often non-linear, interactive and
autocorrelated. Our package helps capture this complexity and offers
functions that construct, fit and conduct inference on a wide range of
highly flexible models that are routinely used for single-locus
landscape genetics studies but are rarely extended to estimate response
functions for multiple loci. To demonstrate the package’s broad
functionality, we test its ability to recover landscape relationships
from simulated genomic data. We also apply the package to two empirical
case studies. In the first we estimate variation in the population-level
genetic composition of North American balsam poplar (Populus
balsamifera, Salicaceae) and in the second we recover individual-level
landscapes while estimating host drivers of feline immunodeficiency
virus genetic spread in bobcats (Lynx rufus). The ability to model
thousands of loci collectively and compare models from linear regression
to extreme gradient boosting, within the same analytical framework, has
the potential to be transformative. The MrIML framework is also
extendable and not limited to mapping genetic change, for example, it
can be used to quantify the environmental driver sof microbiomes and
coinfection dynamics.

Authors: Hu Tao , Mao Xianqiang , Lu Xuedu , Gerilla-Teknomo Gloria P.
Published: December 2020

Local air pollutants (LAPs), such as carbon monoxide, hydrocarbon, sulfur oxide, nitrogen oxide, ozone, and particulate matter, as well as greenhouse gas (GHG) emissions from the transport sector are rapidly increasing in the People’s Republic of China. Various measures to control LAPs have been implemented in the country, along with the adoption of strategies to mitigate GHG emissions. The connection between LAP and GHG emission control and reduction offers an opportunity to address both problems simultaneously. This paper presents a methodology that measures the benefits of co-control evaluation on mitigating LAP and GHG emissions. It highlights the methodology’s potential to help maximize measures and strategies that have significant co-control effects.

Published: December 2020

Teacher research activity is an important complex part of their work. Therefore, alongside with the other, their important professional competences, teacher research activity competence becomes a significant one. Teacher’s activity space has widened a lot. Carrying out various research, the teacher uses the obtained information firstly for their activity improvement. It is obvious that there is a lack of reliable research on this question. A deep gap exists between educational research and educational practice. This research aimed to ascertain primary school teachers’ position on educational research question. The research was carried out in 2019, in which 106 primary school teachers from various Lithuanian schools took part. A two-part research instrument was applied, which consisted of open-ended and closed-ended questions. A descriptive qualitative and quantitative content analysis was carried out. Though most of the teachers thought that educational research was important for their practical activity, however, the biggest gap between educational research and educational practice is most frequently determined by the lack of teacher competence in this sphere. There exists an obvious teacher support need as well as teacher professional development needs in the aspect of research availability/accessibility and its use in educational practice.

Authors: Tushnova Yulya
Published: December 2020

The attention of modern society to intellectual potential makes the problem of studying mathematically gifted youth at the stage of self-determination in higher education relevant. Practical problems related to the psychological features of social adaptation of mathematically gifted youth require solving. The main goal of the research is to study the social and perceptual abilities of mathematically gifted students. The study sample consisted of 76 natural science students aged 17-23 years (M=19.8, SD=3.2 (58% men). The research methods were: testing (test of analytical mathematical abilities, test of the structure of intelligence (TSI) of R. Amthauer), expert assessment, survey (questionnaire of V. A. Krutetsky, questionnaires aimed at diagnosing socio-perceptual abilities), statistical methods. Self-assessment of intelligence, composite assessment, and some components of social intelligence and some components of empathy are significantly different. The ability of mathematical generalization and practical mathematical thinking have a greater number of relationships with social and perceptual properties. Here we found relationships not only with empathy, but also the ability to recognize verbal expression and the General ability to understand and manage their own and other people’s emotions. The ability to operate images in two-dimensional space is related only to the level and components of emotional intelligence. According to the results of the study, the features of socio-perceptual properties of students with different levels of analytical mathematical abilities are described. The conclusions can be used in the development of a program of psychological support for this category of students.

The need for high-viscosity oil production in the fields of the Russian Federation is substantiated. The technology of high-viscosity oil production by the thermoshaft method is considered, harmful and hazardous factors at the workplaces of the underground group workers are identified, first of all, the microclimate parameters (increased air temperature of the working area), which effect on the formation of occupational diseases and an increase in the risk of injury to the personnel. The main problems associated with the imperfection of the technology of the thermoshaft method for the extraction of high-viscosity oil, which effect on the safety of conducting operations for the extraction of heavy oil, are investigated, and presented. The options of opening up a high-viscosity oil field with a modular mine, which allows to normalize the thermal regime in mine workings, improve working conditions of the oil miners, reduce the level of occupational diseases and injury rate, reduce the volume of work and the costs of mining operations and maintenance of the mine workings, are considered. The system for the development of the Yaregskoye field of high-viscosity oil with the division of the mine field into separate production blocks using a sectional ventilation scheme, which provides for independent ventilation of each module due to the construction of an air supply and air exhaust shafts in each block-module of the mine is proposed in the article. The surface and underground complex of shafts for the construction of a modular mine is presented. The calculation is carried out and the results of technical solutions for airing various modifications of mini — mines are given. The drilling gallery was designed, which is typical for all the options of opening. In the designed modular mines, a closed oil gathering system is proposed. Comparative economic analysis showed the efficiency of the development of new areas of the Yaregskoye high-viscosity oil field using the construction of modular mines.

Published: December 2020

The conditions and features are given concerning the degassing of outburst-prone coal seams by wells drilled from the underground workings in the plane of the mined seam. Technological schemes for the location of wells in the mining areas during the preparation and development of the coal seams prone to sudden outbursts of coal and gas were substantiated taking into account the coal strength determined using the method of M.M. Protodyakonov. The scheme of coal seams degassing by wells oriented to the working face line is recommended with a coal strength factor f ≥ 1.3, the degassing scheme with crossed wells — at f < 1.3. The wells are drilled parallel to the working face line and oriented to it. The schemes are implemented in the shallow mines of Karaganda (Kazakhstan), Ukraine and China. Degassing of coal seams not unloaded from the rock pressure by crossing wells ensured an increase in methane production from 1 ton of coal by 0.4–4.8 m3 in the conditions of seams with different coal strength. The highest indicators were achieved in the powerful outburst-prone seams with a coal strength factor of f = 0.3–0.8 in the conditions of the mines of Karaganda Basin, where the volumes of methane extraction by crossing wells were 5.0–5.6 m3 per ton of the degassed coal reserves in the working areas. In the conditions of the outburst-prone shallow seams of Ukraine, the volumes of methane extraction from 1 ton of the degassed coal reserves on the medium density seams amounted to 2.5–4.4 m3 with a coal strength factor of f = 0.6–1.1. 2-2.3 m3 of methane was removed from 1 ton of coal at the Dziulishan mine (China) at a strongly crushed coal layer II1 with a strength factor f = 0.3–0.6. The use of degassing schemes for gas-bearing and outburst-prone coal seams ensures an increase in the productivity of working faces and, as a result, high economic indicators.

The settlements and cemeteries of the Sintashta – type (21st–18th century BC) are concentrated in the southern Trans-Urals steppe. The earliest stage of investigations was related to the decoding of aerial photos that allowed specialists to discover and identify the majority of the settlements. This report presents the results of a geophysical investigation at the Andreevskoye settlement, where we conducted micro-magnetic and ground penetrating radar (GPR) surveys. Magnetic studies have provided new information on the structure of the fortifications and the number and location of houses in the settlements during their occupancy, as well as on the many wells discovered inside the houses. Drawing on our data, a new plan of the settlement was produced, more accurate than the one prepared solely from interpretations of aerial photographs. The settlement consists of multiple layers and is characterized by a complex configuration formed from three rectangular systems of defensive structures. We obtained GPR deep sections along three profiles, indicating the ditches and dwellings of the ancient settlement under sediments and the ruins of walls. Based on these data, we conclude that the depth from the modern surface of the earth to the occupation layer in the dwellings of the ancient settlement is approximately 50–70 cm. Our results provide archaeologists with reliable data that are necessary for the selection of excavation sites.
Advances in Archaeological Soil Chemistry in Central Europe

Analytical technologies for the evaluation of archaeological soils have developed rapidly in recent decades, and now support a range of innovative research and interpretations of archaeological sites and landscapes. Established methods, including phosphates and multi-element ICP-MS/OES, have provided interpretations of the use of space within settlements and houses, and the function of specific archaeological features. Recently, portable X-Ray Fluorescence has been introduced to archaeological soil science, but published results have generated knowledge gaps. The correspondence between archaeological geochemical anomalies and specific human activities is partly dependent on geology (including sediment type and relative acidity and permeability of the soil), topography, and formation processes, as well as influence of human activities. At the same time, which elements, and fractions of elements, are measured is largely dependent on instrument parameters and extraction methods. This paper provides an overview of archaeological soil chemistry in Central Europe, and the current state-of-the-art, followed by an assessment of future developments in archaeological soil chemistry, molecular biogeochemistry, and the significance of geoarchaeology in multi-disciplinary research.

Created in France in May 2007 by Joseph Kovacik and Sabrina Save, Amélie is a small independent laboratory, staffed and partnered with the best specialists in Europe, providing palaeo-environmental and archaeometric services to the French Archaeology community. During its 13 years of existence, Amélie and its owners have been through many hurdles and run fantastic projects, always trying to be forward-thinking and bring high-level research and academia into commercial archaeology, while ensuring the sustainability of the company. One example of their endeavour to innovate is the theoretical framework and methodology they developed to survey large mechanically-stripped archaeological surfaces with pXRF to investigate human impact on soil chemistry. In February 2018, while the future of Amélie was unclear due to three consecutive years of declining turnover, a short stay in Cambridge as visiting scholars re-focused Joseph and Sabrina, with them deciding to launch a new project: the creation of a new facility dedicated to the production of micromorphological thin sections, Terrascope. Since this Cambridge sabbatical, many exciting projects have emerged and reshaped the future of Amélie, Joseph, and Sabrina. This is their backstory.

Published: December 2020

The rice bug, Leptocorisa acuta is one of the major and destructive pests of rice. The experiments were conducted to study on the extent of damage of rice bug, Leptocorisa acuta and to determine the efficacy of five insecticides. The experiments were laid out in a Randomized Complete Block Design (RCBD) with three replications of each treatment. From the study it was found that the infestation rate was in linear progress and the hill infestation was 5.42 to 13.75%, panicle infestation was 27.27 to 54.55%, grain infestation was 4.70 to 7.58% and partial grain infestation was 1.82 to 2.58% respectively. After using different treatments, it was found that the maximum percent of infestation was observed in control and minimum was in Malathion 57 EC treated plot. The maximum no. of grain per panicle was observed in case of Malathion 57 EC (206.4), whereas the minimum was observed in Control (172.6) plot. Malathion and Neem oil showed similar effect when yield was compared while the minimum yield was observed in control treatment. The efficacy of insecticides was ranked as Malathion 57 EC > Azadiractin 2% > Chlorpyrifos 20 EC > Voliam flexi 300 SC > Imidacloprid 17.8 SL.

The study area is underlain by the ultrabasic rock of partly Sabah Ophiolite Complex of Cretaceous ages. The objectives of this study are to determine the Q-value and to estimate the permanent support measures for 20m span, 10m high and eastern direction of the proposed tunnel in the study area. Engineering geological mapping (lithological and surface mapping and discontinuity survey), laboratory study (petrographical study) and testing (Uniaxial Compressive Strength testing) and data analysis (stereographic plots, Q system parameters evaluation and support estimation) was used in this study. The results show that the rock mass is classified as lherzolite, strong, excellent quality, more than four joint sets, slightly altered discontinuity wall, dry excavation and favourable stress condition. The equivalence dimension (De) are 15.4 for the permanent roof. The Q-value for permanent roof and wall of the proposed tunnel are 1.4 (Class D or poor and type 5) and 3.5 (Class D or poor and type 3), respectively. The permanent and temporary supports for the roof and wall are systematic bolting, 700J energy absorption of fiber reinforce sprayed concrete, 9-12 and 5- 6 cm thick fiber reinforce shotcrete, respectively.

Published: December 2020

Geochemical studies of weathering profiles around Kitibi-Iwoye revealed redistribution of elements from parental pegmatite to the regolith. Geological mapping showed that the pegmatite intrudes diorite and migmatite gneiss. Weathered samples from B-horizon were air-dried, pulverised and analysed using X-ray Fluorescence Spectrometry (XRF) in the Department of Geological Sciences, University of Cape Town, South Africa. Chemical Index of Alteration (CIA), Weathering Index of Parker (WIP), Mass balance calculation and Al2O3 – CaO+Na2O – K2O (A–CN–K) ternary plot were employed to determine elemental mobility and distribution caused by weathering. SiO₂ (74.2 and 43.4 wt %), CaO (0.43 and 0.03 wt. %), Na2O (7.14 and 0.04 wt. %), K2O (1.90 and 0.67 wt. %), MnO (0.11 and 0.03 wt. %) and P2O5 (0.20 and 0.05wt. %) displayed depletion from parent rock to the regolith respectively. But Al₂O₃ (15.5 wt. % and 33.5 wt. %), Fe2O3 (0.39 and 3.40 wt. %), TiO2 (0.04 and 0.35 wt. %) and MgO (0.08 and 0.11 wt. %) showed enrichment from parent rock to the regolith respectively. Fe₂O₃ (3.19) is the most enriched whereas Na2O (-99.8), CaO (-98.9), P2O5 (-95.3), K2O (-89.5), SiO2 (-81.9), MgO (-73.1), MnO (-64.5) and Al2O3 (-23.6) are progressively depleted. Mean CIA value of 97.8 revealed that weathering has almost reached its completion whereas CIA of 62.1 for the pegmatite suggested that the parent rock is at incipient stage of weathering. Pegmatite had a WIP of 110.5 whereas the weathered samples with WIP ranging from 2.66, 3.88, 6.03, 6.23, 6.92, 8.08, 9.08, 9.76 and 14.6 respectively showed decreasing trend of weathering. This study confirmed contrasting behaviour of CIA and WIP. A-CN-K diagram suggested strongly weathered samples plotted at the apex of Al2O3 field whereas pegmatite plots along the A-CN line.

Published: December 2020

Vertical Electrical Sounding (VES) was conducted in Salbi farm in the fractured Basement Complex, North- Central Nigeria to determine the groundwater resource potential to serve for agricultural purposes. Four VES stations using Schlumberger electrode configuration with a maximum current electrode spread of 300m were employed for data acquisition. ZHODY software was employed in computing resistivities, depths and thicknesses of the various layers and curve types. Results indicate that the area is characterized by 3 distinct geoelectric layers inferred differently at the VES locations. One potential groundwater aquifer zone was delineated at VES 1, 2, and 4 within the fractured/weathered basement columns having depths ranging between 48.8 – 59.60m and resistivities ranging between 213 – 513 Ωm. These results suggest that boreholes for sustainable groundwater supply in Salbi farm should be sited either at VES 1, 2 or 4 location and screened at a depth ≥60.0m. Wells to develop this resource should be drilled to an effective depth of 40 to 60 m for optimum yields. It is recommended that pumping test be done in order to further determine the aquifer efficiency and productivity in the area. However, the aquifers at these locations have potentials for groundwater but may be vulnerable to contamination.

The experiment was carried out at the research field of Agricultural Research Station, BARI, Dinajpur during Mid December to end of November for two consecutive years (2017-18 and 2018-19) to develop an economically sustainable and profitable cropping pattern over existing pattern. Three alternate cropping patterns Tomato-T. Aus-T. Aman, Tomato-Summer onion-T. Aman, Tomato-Indian Spinach-T. Aman were introduced against the existing cropping pattern Tomato–Fallow–T. Aman rice. The experiment was carried out in RCB design with three replications. The highest REY (35.91 t/ha) was recorded from the cropping pattern Tomato-Indian Spinach-T. Aman followed by Tomato-Summer onion-T. Aman (31.26 t/ha) and Tomato-T. Aus-T. Aman (29.04 t/ha). The lowest REY (24.48 t/ha) was obtained from the cropping pattern Tomato-Fallow-T. Aman (Farmers practice). The gross return and gross margin were higher in the alternate cropping patterns compared to existing cropping pattern due to additional yield of T. Aus rice, Summer Onion and Indian Spinach. Therefore, farmers in Dinajpur region of Bangladesh could follow alternate cropping pattern in their medium high land where lands remain fallow after harvesting of Tomato for higher crop productivity and profitability.

Authors: Sharma Swastika , Kandel Nisha , Chaudhary Pooja , Rai Priyanka
Published: December 2020

Wheat is one of the staple foods of the Nepalese diet which is grown in the winter season in most of the areas of our country. This short review article analyses the previous works and studies to investigate the role of various micro and macronutrients in wheat crops. Long-time research which was conducted in several locations has shown that in addition to natural resource deterioration and biotic-abiotic stress, deficiency of multiple nutrients is also an essential factor that influences yield reduction, productivity declination, and shrinkage in net profit. Therefore, Integrated Nutrient Management in terms of using chemical fertilizers in conjugation with organic manures as well as biological inputs is needed to improve the nutrient status of the soil. INM increases the nutrient uptake rate of the plant and influences the nutrient supply in the soil system. As soil is the primary source of nutrients, any degradation in the quality of soil can create a reduction in crop yield. Hence the adoption of suitable measures is highly necessary for sustaining the environment and enhancing productivity.

Modern biotechnology enables an organism to produce a totally new product which the organism does not or cannot produce normally through the incorporation of the technology of ‘Genetic engineering’. Biotechnology shows its technical merits and new development prospects in breeding of new plants varieties with high and stable yield, good quality, as well as stress tolerance and resistance. Some of the most prevailing problems faced in agricultural ecosystems could be solved with the introduction of transgenic crops incorporated with traits for insect pest resistance, herbicide tolerance and resistance to viral diseases. Plant biotechnology has gained importance in the recent past for increasing the quality and quantity of agricultural, horticultural, ornamental plants, and in manipulating the plants for improved agronomic performance. Recent developments in the genome sequencing will have far reaching implications for future agriculture. From this study, we can know that the developing world adopts these fast-changing technologies soon and harness their unprecedented potential for the future benefit of human being.

The jute yellow mite Polyphagotarsonemus latus constitutes one of the major pests of jute crop in Bangladesh. The objective of this work was to find out the sources of resistance/tolerance accessions against jute yellow mite. This experiment was carried out in the fields of Bangladesh Agricultural University, Mymensingh, JAES, Manikganj and the Central station, BJRI, Dhaka, during jute growing seasons 2011 and 2012. Out of 79 accessions, only 13 accessions were found less susceptible to yellow mite. These accessions were studied further in the field and net-house condition. Considering the level of infestation in the net-house condition only three accessions namely 1510, 890 and 33-1-244 (A) 2 were found to perform better showing 9.75, 9.68 and 9.93% infestation. In field condition, in case of olitorius, accession 1510 showed lowest infestations (9.90%) giving maximum plant height 324.15 cm and yield 3.26 ton/ha. In case of capsularis, accession 890 also resulted minimum infestation (10.23%) giving satisfactory plant height 315.27 cm and yield 3.14 ton/ha respectively. Accessions 1510, 890 and 33-1-244 (A) 2 could be recommended as breeding materials for evolving yellow mite resistant jute variety.
A REVIEW ON GREENING DISEASE AND INTEGRATED MANAGEMENT OF CANDIDATUS LIBERIBACTER SPECIES IN CITRUS
Authors: Joshi Priyanka , Khanal Shovit
Published: December 2020

Citrus greening disease, recently known as huanglongbing disease, is known to wreak havoc not only in Nepal but across the globe as it is non-curable once trees are affected. In 1919, this disease was reported first time in China, most likely originating from Taiwan. It then spread to more than a hundred countries and was recorded in Nepal for the first time from Pokhara Valley in 1968. Till now, there is no established solution for this century-old and yet, newly evolving disease. Being a vector-borne bacterial disease, the use of antibiotics had been a practice on a large scale that had led to the development of resistance. This disease has been more challenging to the developing and least- developed countries like Nepal. Thus, this paper aims to solve the problems of all the farmers engaged in citriculture by making them aware of the best-integrated management approaches that would help them increase their productivity and ultimately contribute to food security and sustainability. Detailed information about the disease, together with various techniques for integrated management and control of this disease is in this review. Thus, this paper will help farmers, traders, and planners.
