Subject: Finite element-based simulation and analysis of dragline bucket in static and dynamic loading condition
Keywords: Dragline bucket, loading conditions, static and dynamic.
Abstract: Draglines are bulky and expensive machines widely utilized in opencast mines for overburden stripping. Due to tedious working conditions, a variety of fatigue
failures in dragline components are common. Bucket is one of the main components of dragline, and it is a
source of external load on the machinery than its interaction through broken rock material directly. Hence, dragline buckets are the most vulnerable components of wear, tear and related failures. This
article analyses the von Mises stresses using the finite element method (FEM) under the static and dynamic loading conditions. In this study, the three-dimensional solid bucket models were developed in AUTO
CAD and were investigated for stress, deformation, and safety factor on the dragline bucket under static and dynamic loading conditions using the ANSYS 18 software. FEM outcomes have been highlighted from teeth, the arc of anchors and hitch elements have a maximum value of stress and a minimum value of safety factor under various loading conditions. The purpose of this study was to prognosticate the bucket failure, the strength of bucket teeth and identify the sensitive areas of the dragline bucket.

Abstract: Decolourization potential of microalgal biomass of an unicellular green alga (Chlorella vulgaris) was studied using different concentrations of Orange-G dye.
Several parameters were also optimized for better removal of the tested dye from its aqueous solution. Langmuir and Freundlich models were tested for equilibrium studies and experimental data of the present study are better explained by the Freundlich
model. FTIR data showed that five functional groups were probably involved in the adsorption of the dye. The biosorption process using algae (including C. vulgaris) offers an excellent biosystem for the remediation of final discharge of textile effluents.

Keywords: Aromatic rice, grain quality, lodging resistance, semi-dwarf gene.
Abstract: Kalanamak is an important aromatic rice variety in India. Tall stature of Kalanamak causes lodging due to which its yield and other characters severely declines. Introgression of the semi-dwarfing gene (sd1) from CSR10 was performed with the help of marker assisted breeding. Backcross-derived plants were characterized for semi-dwarf nature. Improved Kalanamak lines were analysed for the sd1 gene and to
check the presence of aroma, sensory analysis test and amplification with betaine aldehyde dehydrogenase (badh 2) derived primer was performed. Improved
versions of Kalanamak rice lines were either on par or superior in terms of yield, grain type and cooking quality with reduced height implicating the potentiality of marker-assisted backcross breeding for improvement of this rice variety.

Subject: A dynamical model of growth of membership to an opinion
Keywords: Dynamic model, growth of membership, opinion dynamics, social engineering.
Abstract: Many social processes, from elections to terrorism, depend on growth of memberships to opinions. In a generic sense, an opinion is a proposition that for an individual has financial, cultural and emotional implications. The individual responses in turn create a ‘social response’ which influences the individual response
resulting in a dynamical system with two-way feedbacks. We consider a set of deterministic dynamical equations that describe individual response to a class
of prescribed opinions. The time-dependent opinion dynamics model exhibits nearly complete acceptance to nearly complete rejection with complex evolution,
providing the framework for a mechanistic description of opinion formation.

Subject: Current rice farming, water resources and micro-irrigation
Keywords: Micro-irrigation, rice farming, water resources and availability, water use efficiency.
Abstract: Rice is the staple food for half of the world’s population, and rice farming is a livelihood for millions of farmers in Asia. In India, it provides an individual with 32% of the total calorie and 24% of the total protein daily. This crop is mostly grown in puddled soil
by transplanting, and flood irrigation is practised by farmers. Water or irrigation input to transplanted rice typically ranges from 1000 to 2000 mm depending upon the growing season, climatic condition, soil type and hydrological conditions. Facing water scarcity and climate change, reducing water requirement of this crop is a challenge. Out of 42.75 million hectare
(m ha) rice area, only 25.12 m ha is under irrigation. Regarding water resources, depletion of groundwater is alarming in the north Indian states. On the other hand, it is under-utilized in eastern India. Micro irrigation, i.e. sprinkler and drip methods have been used with the aim of minimizing water use and enhancing water use efficiency of rice. In addition, evidence-based scientific understandings on micro irrigation for rice have been elucidated in this article. The potential of drip or sprinkler irrigation to rice on water saving as well as scientific insight and critical appraisal have been expounded on reasons of yield reduction. This comprehensive treatise would facilitate the formulation of strategies or policies on efficient management of water or irrigation for rice cultivation.

Subject: Marine spatial planning for resource conservation, fisheries management and for ensuring fishermen security – global perspectives and Indian initiatives
Keywords: Fishermen security, mariculture, marine spatial planning, resource conservation, satellite-based technology.
Abstract: Internationally, marine spatial planning (MSP) is an integral part of the decision-making protocol for setting up activities in the marine zone, be it the establishment of industries, exploration and mining
for oil and minerals, deciding of surface transport, ensuring national security, exploitation of living and non-living resources, or conservation and management of resources and ecosystems. Satellite-based technologies like remote sensing and geographic information system are two powerful tools that provide
a common platform to present information on different activities from the marine zone. This would enable the planners and policymakers to interpret the interaction between various factors and derive judicious decisions on the allocation of space and resources to different segments or activities in marine zone. This article reviews how MSP is being used as a decision support tool in various countries for the peaceful coexistence of different stakeholders in the marine zone. It also discusses initiatives in India along with a
reminder on the responsibility of the country as a signatory of international organizations to give importance on developing MSP for the conservation of
resources as well as marine ecosystems.

Subject: Genetic gain for yield in rice breeding and rice production in India to meet with the demand from increased human population
Keywords: Attainable yield, breeding, genetic gain, potential yield, mega environments, Oryza, population, production, rice.
Abstract: Our objective was to estimate genetic gain for yields in genotypes tested in 11 rice ecosystems from 1995 to 2013 in India and compare the growth trend of human
population and national rice grain production in 1974 to 2013. In each ecosystem, the check used remained
the same over years but showed similar and significant increases along with top-3 genotypes and experimental mean grain yields derived from sets of genotypes that varied with the year. Therefore, when
environmental effects were eliminated, there was no significant genetic gain in yield of genotypes. Annually human population grew linearly at 16.203 million persons and rice production at 1.943 million tonnes (mt) during 1974–1994. This growth slowed during 1995–2013 in population by 16.131 million persons and in rice production by 1.2753 mt. Breeding for higher genetic yields should be restricted to the four mega environments which offer scope and exploit the unfolding advancements in rice genomics. The national average yield of un-milled rice was 3.76 t/ha. Evidence indicates that the potential yield in rice is 15–16 t/ha
and yields of 10 t/ha is attainable in relatively risk-free irrigated (~20 m ha) and rainfed shallow lowland (11 m ha) ecosystems. Closing yield gap (~6 t/ha)
through corrective technological and policy interventions is urgently needed to ensure rice availability to match with the demands of growing population.

Subject: Slope stability analysis with reference to rainfall infiltration in the Yongping Copper Mine, China
Keywords: Failure probability, open-pit mine, rainfall infiltration, safety factor, slope stability.
Abstract: Due to the influence of rainfall infiltration, the slope of Yongping Copper Mine appears to have a high probability of instability, posing a great threat to the mineral transportation roads and mining
safety. In this study, the hydraulic response of the slope under rainfall conditions is simulated, the response of the slope under different rainfall conditions is discussed, and the safety factor (FS) and the probability of failure (Pf) of the slope during and after a rainfall are analysed. The results indicate that rainfall infiltration has a hysteretic effect on slope instability. The failure of the mining slope at the elevation between 178 m and 226 m is likely to occur in three days after a rainfall. The activity distribution of the slope indicates that it is an advancing landslide.

Subject: Low-cost hydroponic fodder production technology for sustainable livestock farming during fodder scarcity
Keywords: hydroponic fodder production,sustainable livestock farming, fodder scarcity
Abstract: Availability of quality green fodder has
always been a challenge to livestock
farmers. The green fodder deficit in India
is reported to be 24.81%, which is mainly due to the decline in pasture lands in the urbanization era and vagaries in
monsoon. Conventional fodder crops are
grown in soil which involves large land
area, more manpower and huge amounts
of water. Alternative means to ensure
fodder production for feeding livestock
is an urgent priority. Hydroponic fodder
production is one such technology to increase green fodder production by vertical farming which requires less land,
water as well as manpower. The term
‘hydroponics’ was derived from the
Greek word ‘hydro’ meaning water and
‘ponos’ meaning labour. This system
helps overcome the challenges of climatic change and also helps in production
system management for efficient utilization of natural resources and mitigating
malnutrition . Hence, the present study
was envisaged to assess the feasibility of
low-cost techniques using six experiments in a low-cost hydroponic fodder
unit for the production of hydroponic
green fodder for sustainable livestock
farming during fodder scarcity.

Keywords: Biodiversity conservation, Agriculture, nutrition, health, climate change
Abstract: At a time when it seemed that continued
availability of biodiversity in general,
and agro-biodiversity in particular was
taken for granted, one of us (MSS) as
early as January 1983 in his Presidential
address at the 15th International Congress of Genetics, held in New Delhi
drew attention of the delegates to the importance of conservation of biodiversity
of all organisms from ‘microbes to man’.
More than fifty years ago, it had
occurred only to a few geneticists that
there would be no plant breeding at all,
whether molecular or Mendelian, should
all the wild progenitors and related species of the cultivated crops become extinct. Since then, with his persuasion at
the international level and also direct
involvement, efforts to prevent the extinction of biodiversity by methods such
as cryogenic preservation and in situ
on-farm conservation have been intensified.

Abstract: According to the Gutenberg–Richter
law., at least one earthquake of magnitude greater than 7 occurs every month
along the seismically active belts in the
world. Earthquakes are the manifestation
of fault slip at depths, thus, there is no
direct method to measure or observe
them. However, seismometers can record
ground velocity or acceleration caused
by the occurrence of an earthquake when
a fault slip occurs at depth. Therefore,
setting up a seismic network is inevitable
to understand the physics of earthquake
processes, thereby, mitigating earthquake
hazard.

Most of these books are by foreign authors from developed countries – mainly journalists or scientists. Some of these books try to convince the reader that climate change is a natural phenomenon and that the society can learn to adapt to it. The books written by scientists tend to convince the reader that human beings are responsible for the rapid warming of the earth during the past 50 years. The books written by journalists tend to focus on the politics surrounding the attribution of climate change to human actions. Most of these books do not discuss, in great detail,
what we can do to arrest global warming

Subject: Studies on mutation breeding in mandarin variety Kinnow
Keywords: Flowering characters, fruit weight, pollen viability, seedless.
Abstract: The present study was undertaken to generate variability in Kinnow (Citrus nobilis Lour × C. deliciosa Tenora) using gamma radiation. Four hundred buds of Kinnow were irradiated at 30 Gy and budded on
rough lemon rootstock in February 2007. The resulting 188 MV1 plants were planted in the field in October 2009 and observations in the present trial were
recorded from 2015 to 2018. The number of bold seed per fruit ranged from 0.4 to 30.8 in the population raised from irradiated buds. Out of all the branches, 6.4% had bold seed number less than 10.3 per fruit,
39.4% had bold seed number from 10.3 to 20.3 per fruit and 54.7% plants had bold seed number more than 20.3 per fruit. The average fruit weight in treated population ranged from 94.3 to 253.2 g, with 46.8%
bearing small sized fruits, 44.3% bearing medium sized fruits and 8.9% bearing large sized fruits. High variability was also observed for plant height, plant spread, pollen viability and total soluble solids.
Among the 188 MV1 plants, eleven Kinnow mutants (seven solid mutant trees and four mutant branches) having average seed number less than eight were identified, showing distinct desirable characters and were compared in detail with parent variety Kinnow.

Subject: Allocation of biomass and carbon stocks in seven woody species of tropical deciduous forests, Dang, Gujarat
Keywords: Biomass estimation, carbon sequestration, climate change, Indian forests, tropical deciduous forests.
Abstract: Literature on the biomass estimates and carbon cycles of Asian tropical deciduous forests is very limited. In this study, seven woody species were selected, with
four representatives each in chronosequence, and harvested from deciduous forests of Dang, Gujarat for
assessing their biomass and carbon content. All the species showed a carbon percentage between 40% and 45%. The regression equations of total biomass versus girth class developed for all seven species would be useful to estimate biomass on a larger scale and the
carbon content would improve the understanding about carbon accounts of Indian forests.
