In this study, the Agro-ecological zones (AEZs) of Uttarakhand were delineated based on land use/land cover, slope, soil texture, temperature and length of growing period (LGP) by using remote ...sensing and GIS. The Decision Tree Classifier (DTC) algorithm technique was used for delineation of Agro-ecological zones (AEZs). The land use/ land cover map was used as base map and slope map of entire state (other than snow bound region) having five classes (0-5°, 5-15°, 15-30°, 30-50° and >50°) was overlaid on soil texture map having three soil classes (frigid soils, loamy soils and sandy soils). Thereafter, temperature map with three thermal regimes (<0°C, 0-15°C, and >15°C) and length of growing period with two distinct classes (<120 days and >120 days) were overlaid on existing map. The small classes having number of pixel <1000 and the regions having temperature <0°C and slope of >50° were removed from the analysis because agriculture is not possible over these regions. Thereafter, the entire state of Uttarakhand was divided into 38 agro-ecological zones (AEZs).
Agriclinics and Agribusiness Center (ACABC) scheme was launched by the Government of India in 2003 as a strategy for boosting agribusiness in the country through agriculture graduates. Since its ...inception, a substantial number of agribusiness of different kinds started in the country, and hence expanded the agribusiness environment in the country, employed a vast population, and stretched extension services to the needy farmers even in remote villages. Therefore, it was essential to understand the panoramas of the scheme from its stakeholders. Hence the perception of the agripreneurs about the ACABC scheme was examined by measuring the strengths, weaknesses, opportunities, and threats quantitatively by combining SWOT with the analytical hierarchy process (AHP). A one-day interaction meet consisting of successful agripreneurs under the Nodal Training Institute (NTI)-Varanasi was held in Varanasi (UP), in October 2018 to administer the SWOT-AHP analysis. The results revealed that ACABC scheme had high positive (84.7%) features, and act as a suitable plan for promoting agribusinesses. The most significant positive features were the potentiality of employment generation under the scheme and the favourable attitude of self-employment among agriculture graduates. Delays in subsidy release under the scheme and less practical exposure of successful agribusiness to trainees under the scheme were the areas that need improvement which impedes the success of the scheme. The greater success of the scheme will enhance self-employment among agriculture graduates who will supplement the efforts of public extension by necessarily providing extension and other services to the farmers and, hence ACABC scheme can support the efforts of the Government for doubling the incomes of farmers.
Background
Immunodeficiency, centromeric instability, and facial anomalies (ICF) syndrome is a rare, genetically heterogeneous, autosomal recessive disorder. Patients suffer from recurrent infections ...caused by reduced levels or absence of serum immunoglobulins. Genetically, 4 subtypes of ICF syndrome have been identified to date: ICF1 (DNMT3B mutations), ICF2 (ZBTB24 mutations), ICF3 (CDCA7 mutations), and ICF4 (HELLS mutations).
Aim
To study the mutation spectrum in ICF syndrome.
Materials and methods
Genetic studies were performed in peripheral blood lymphocyte DNA from suspected ICF patients and family members.
Results
We describe 7 ICF1 patients and 6 novel missense mutations in DNMT3B, affecting highly conserved residues in the catalytic domain. We also describe 5 new ICF2 patients, one of them carrying a homozygous deletion of the complete ZBTB24 locus. In a meta‐analysis of all published ICF cases, we observed a gender bias in ICF2 with 79% male patients.
Discussion
The biallelic deletion of ZBTB24 provides strong support for the hypothesis that most ICF2 patients suffer from a ZBTB24 loss of function mechanism and confirms that complete absence of ZBTB24 is compatible with human life. This is in contrast to the observed early embryonic lethality in mice lacking functional Zbtb24. The observed gender bias seems to be restricted to ICF2 as it is not observed in the ICF1 cohort.
Conclusion
Our study expands the mutation spectrum in ICF syndrome and supports that DNMT3B and ZBTB24 are the most common disease genes.
The vulnerability of animal production to Thermal Humidity Index (THI) has hardly been documented in India and hence one study on climate and weather on the conception rate of cattle was conducted at ...Pantnagar, Uttarakhand. In the study, meteorological data (2000 to 2010) were collected from agrometeorological Observatory, Pantnagar and were used to compute six different types of Thermal Humidity Index by giving different weightage to dry bulb temperature and humidity. The relationship between Thermal Humidity Index and overall conception rate of animal was established to select the most appropriate THI for practical application.
This paper proposes a nanorobotic fiber fabrication method which uses proximal probes to draw polymer fibers down to few hundred nanometers in diameter and several hundred micrometers in length. ...Using proximal probes such as Atomic Force Microscope (AFM) and Scanning Tunneling Microscope (STM) or glass micropipettes, liquid polymers dissolved in a solvent are drawn. During drawing, the solvent evaporates in real-time which solidifies the fiber. Controlling the drawn fibers trajectory and solidification in three-dimensions (3-D), suspended fibers, fiber cantilevers, custom 3-D fibers, and fiber networks, are proposed to be fabricated. Poly(methyl methacrylate) (PMMA) polymer dissolved in chlorobenzene is used to form a variety of suspended polymer fibers with diameters from few microns to 200nm. Fabrication of crossed and linear networks of fibers is also demonstrated. Viscoelastic modeling of polymer fiber drawing is realized using a finite element method to test the significance of the drawing speed and velocity profile on the extensional behavior of the drawn fiber. Since the mechanical properties of the drawn micro/nanofibers could vary from the bulk polymer material significantly, mechanical characterization of suspended fibers using an AFM and a Nanoindenter setup is proposed. Extending this technique to a variety of nonconductive and electroactive polymer fibers, many novel applications in micro/nanoscale sensors, actuators, fibrillar structures, and optical and electronic devices would become possible
Indian reservoir’s managers have been facing problem in managing water and fisheries resources due to invasive aquatic weed infestation. Multispectral remote sensing data was used for monitoring the ...growth pattern of world’s worst weed; Giant Salvinia (
S. molesta
Mitchell) in reservoir “Tumaria”, located in the
Terai
region of Uttarakhand (India). Temporal satellite data of Landsat-7 (ETM +) and Landsat-8 (OLI) for the period April, 2013 to May, 2015 were used for mapping and monitoring the weed. It was revealed that the reservoir was free from floating weed Salvinia until June, 2013 and for the first time appeared during September, 2013. It has covered 42% of the water spread area and subsequently covered 92% area until October, 2013. Active growth (matured weed) of Salvinia was observed when it covered 89–92% of water surface from October, 2013 to January, 2014 and also new growth (immatured weed) of Salvinia was observed on same months. Thematic map derived from the study can be used as a decision support tool for controlling aquatic weed infestation.
Yield prediction plays an important role to decide the economy of farmer as well as the country. It avoids the under and over cropping of the particular crop. The production of not only mustard crop ...but all the agricultural crops is mainly affected by the weather variables. The changing weather condition affects the growth and development of crop causing intra seasonal yield variability. In addition, with weather variations, the spatial variability and crop management practices also plays a decisive role. As a result, yield forecasting represents an important tool for optimizing crop yield and to evaluate the crop-area insurance contracts. Considering yield variability and importance of rapeseed-mustard for farmers an attempt has been made to develop a homogeneous zone in respect to inter annual weather induced variability with help of this large region yield prediction could be done easily. For this study the 33 districts of erstwhile Uttar Pradesh has been selected and rapeseed-mustard data have been collected for the year 1997-2016. In this study a three steps approach has been adopted;1) the prediction of trend yield, 2) estimation of yield deviation and cluster formation and 3) mapping of the clusters in GIS and creation of homogeneous zones. Then these homogeneous zones created on basis of weather induced variability were used for yield forecasting of mustard in this region.
