Coarse grained dynamics of the freely cooling granular gas in one dimension

We study the dynamics and structure of clusters in the inhomogeneous clustered regime of a freely cooling granular gas of point particles in one dimension. The coefficient of restitution is modeled as $r_0<1$ or 1 depending on whether the relative speed is greater or smaller than a velocity scale $\delta$. The effective fragmentation rate of a cluster is shown to rise sharply beyond a $\delta$ dependent time scale. This crossover is coincident with the velocity fluctuations within a cluster becoming order $\delta$. Beyond this crossover time, the cluster size distribution develops a nontrivial power law distribution, whose scaling properties are related to those of the velocity fluctuations. We argue that these underlying features are responsible behind the recently observed nontrivial coarsening behaviour in the one dimensional freely cooling granular gas.Comment: 7 Pages, 9 Figure

Linking climate change adaptation and disaster risk reduction: reconceptualizing flood risk governance in Mumbai

Climate-related hazards, urban development and changing vulnerability patterns compel cities across the world to deal with new and emerging forms of risk. Academic literature and recent international policy documents suggest potentials of conceptually and practically linking the fields of climate change adaptation (CCA) and disaster risk reduction (DRR) and emphasize the need to mitigate climate-related risks at local level. However, there is limited knowledge on how this link is established at local levels and the role of ground-level actors and practices therein. Using the case of recurrent and disastrous floods, this paper discusses the significance of linking DRR and CCA in Mumbai. It analyses policies, plans, institutions and interventions related to DRR and CCA and uses interviews and a field study to assess flood risk governance at the level of municipal wards and neighbourhoods. The findings suggest that although flood risk governance has been significantly strengthened, three gaps exist: First, a lack of a comprehensive plan for Mumbai that anticipates future risks and vulnerabilities and integrates CCA and DRR down to local level. Second, a lack of an overarching and decentralized institutional framework across sectors and scales that recognizes the multiplicity of formal and informal actors. Third, the potential of civil society and informal actors for disaster risk management and adaptation planning has not been tapped into sufficiently. The paper argues that potential exists to reconceptualize flood risk governance in Mumbai by focusing on future risks and vulnerabilities and by recognizing the work of informal actors like emergent groups at local level

Carbon Nanotubes Based Porous Framework for Filtration Applications Using Industrial Grinding Waste

Forging, milling, turning, grinding and shaping etc. are the various industrial manufacturing processes which generate the metal waste. Grinding is extensively used in the finishing operation. The waste generated contains significant impurities apart from the metal particles. Due to these significant impurities, it becomes difficult to process and gets usually dumped in the landfills which create environmental problems. Therefore, it becomes essential to reuse metal waste to create value added products. Powder injection molding process is used for producing the porous metal matrix framework. This paper discusses the presented design of the porous framework to be used for the liquid filter application. Different parameters are optimized to obtain the better strength framework with variable porosity. Carbon nanotubes are used as reinforcing materials to enhance the strength of the metal matrix framework

One-Pot Palladium-Catalyzed Ligand- and Metal-Oxidant-Free Aerobic Oxidative Isocyanide Insertion Leading to 2-Amino-substituted-4(3H)-quinazolinones

An efficient, ligand- and metal-oxidant-free, one-pot, cascade aerobic oxidative, palladium-catalyzed, multicomponent reaction has been developed through isocyanide insertion of less active secondary amide and aromatic amine, which leads to 2-amino-substituted-4(3H)-quinazolinones. This approach proves to be one of the simplest methods for the synthesis of this class of valuable bioactive heterocyclic scaffolds

Seasonal variations of phsycio-chemical characteristics of Jamgavan dam water of Hingoli District (M.S.) India.

Jamgavan dam is a minor irrigation dam. The water in Jamgavan dam is used for irrigation, fish culture, drinking and domestic purposes. The present investigation deal with the study of seasonal variations of physicochemical characteristics of Jamgavan dam water. The study was carried out during the year 2007 for a period of 12 months. The parameters such as atmospheric temperature, water temperature, pH, free carbon dioxide, Electrical conductivity and dissolved oxygen were studied.&nbsp

Response of Garlic to Organic and Inorganic Fertilizers

An experiment was carried out to study the response of organic and inorganic fertilizers on growth, yield and quality of garlic (Allium sativum L.) cv. Yamuna Safed-3. The results revealed that the combined application of 25% RDF with 75% N through FYM @ 20 t/ha gave higher marketable bulb yield of 19.34t/ha as compared to other treatments which were statistically on par with 100% RDF (18.53 t/ha ) and 50% RDF + 50% N supplied as FYM (18.94 t/ha). It is suggested that for better biometric observations, bulb characters and marketable bulb yield in garlic, combined use of inorganic and organic source of nutrient supply is preferable

The evaluation of toxic effect (LC 50) of endosulfan on female crab Brytelphusa guerini.

Man with extraordinary intellectual capability conquered the age; old traditional world by establishing modern technological world to cater the needs of all the human beings. As the most intelligent man acquired supremacy and mastery over each and every object on the earth and mode them to keep under his control. The paper deals with the organochlorine pesticide which is regularly used in agricultural purpose interact directly or indirectly with the biosphere spoils the biota flora and the fauna. The endosulfan toxicity calculated by LC 50 and effect of death rate found on the fresh water crab species Barytelphusa guerini. The paper details with mortality rate of experimental animals 50% at each 24 hours. It is calculated by statically and presented by graphically and tabulated by tables.&nbsp

The lethal effect of dimethoate on heart beat rate of female crab Brytelphusa guerini.

The circulatory system is communicating organ system as it communicates with various systems of the body. It ensures proper distribution of the oxygen and nutrients apart from collection of metabolic waste and delivery to excretory organs like kidney. The circulatory body fluids transport various chemical substances necessary for metabolic continuity like hormones etc. The system of structures, consisting of the heart, blood vessels and blood is named as circulatory system. In these animals the system of cavities should be considered as a haemocoel and the blood which fulfils the characters of a circulatory fluid and those of inertial lymph should be caused haemolymph. The pigment haemocyanin is found in the blood of most crustaceans hence it has light blue color. The experimental animals collected from paddy field. The toxic effect of dimethoate resulted to disturb the regular working of heart. In this paper study about the heart rate of female crab. Barytelphusa guerini shows variations from 24 hr; 48 hr; 72 hr and 96 hours. The results are comparatively discussed with using graph and table

Behavioral study of female crab Brytelphusa guerini under acute stress of dimethoate.

Behaviour includes all those process by which an animal senses the external world and internal state of its body, and responds to changes which it perceives. Many of such processes will take place inside the nervous system and may not be directly observed but reflected through the behaviour of the animal. When an organism is exposed to any toxic agent, some changes occur in the behaviour which can be observed externally. These behavioral changes may be co-related to they changes occurring in the nervous system, as different behavioural responses are sub-served wholly or partly be the different neural circuits which are distributed in the nervous system. Earlier reports revealed that there is a strong correlation between physiological activities, metabolic changes and behaviour of animals. The paper deals with toxic effect of dimethoate on fresh water female crab Barytelphusa guerini and its behavioural study. The experimental animal shows various activities which is recorded and discussed.&nbsp; &nbsp
