Opis:
Water harvesting systems are traditional technologies that have met the needs of local populations for many centuries indicating the systems are clearly sustainable. It is simply defined as a method for inducing, collecting, storing and conserving local surface run-off for future productive use. It is one of the oldest and most commonly used sustainable water management systems in India. There are various types of systems to harvest rainwater in India ranging from very simple to the complex industrial systems. Examples of traditional rainwater systems in India include bamboo pipes and Apatani systems of eastern Himalayas, Ghul of western Himalayas, Zabo and Cheo-ozihi of north eastern India, Dongs, Garh and Dara of Brahmaputra valley, Kund, Khadin, Talabs, Beri, Johad, Baoli etc. of Thar desert and Gujrat, the Havelis of Jabalpur, bandh and bandhulia of Satna, virda of Gujarat, ahar-pynes of Bihar, Eri and Kulam of eastern coastal plains, Jackwells of islands, most of which showed immense structural simplicity and high efficiency. Almost all forts in India, built in different terrains and climatic conditions, had elaborate arrangements for drinking water. Most of the old temples in south India built centuries ago have large tanks in their premises. These tanks are either fed by harvested rain water or by tapping underground springs. The traditional water-wisdom at all levels of the society ensured adequate availability of water for all, which in turn, formed the basis for all round development and prosperity. We should again learn and comprehend the ancient knowledge and apply it in our modern society to get rid of the present water stressed condition.

Opis:
Respiratory allergic diseases such as bronchial asthma, rhinitis, urticaria, atopic dermatitis have been steadily increasing all over the world, including India. Owing to its alarming trend, several aerobiological surveys have been undertaken in different parts of India to delineate the variety of pollen and spore load. In this review, we have reported the current state of aerobiological knowladge in India with particular reference to allergenic airborn pollen occurence in 2001–2015. Pollen have been found to contribute a significant proportion in the air and caused allergy symptoms in the local inhabitants. Aerobiological records, a questionnaire survey and hospitalization records have been employed for the analysis. Holoptelea integrifolia, Amaranthus spinosus in northern region, Sorghum vulgare, Pennisetum, Gynandropsis gynandra, Parthenium hysterophorus, Dolichandrone platycalyx in southern regions, and Parthenium hysterophorus from the western region; Cynodon dactylon, Cenchrus ciliaris in the central area; Acacia auriculiformis, Cleome gynandra, Catharanthus roseus, Phoenix sylvestris, Areca catechu, and Lantana camara in the eastern regions as potential aeroallergens in India. The statistical approach confirmed the correlation between hospitalization rate associated with allergy-related health troubles and the prevalent allergenic pollen in the air. The Poaceae group has been found to be dominant throughout India. Immuno-biochemical studies identified various protein with allergenic potential found in the pollen recorded. Epitope identification and homology of the major allergenic protein Cat r1 of Catharanthus sp and Par j 1 of Parietaria judaica have been found. Identification of allergenic pollen grains and the modern approach concerning cross-reactivity and epitope revelation of dominant airborne pollen have important clinical implications for the prevention, diagnosis and treatments of allergic diseases in India.
W ostatnich latach na całym świecie drastycznie wzrasta liczba chorób alergicznych układu oddechowego (astma oskrzelowa, nieżyt nosa) oraz pokrzywka czy atopowe zapalenie skóry. Trend wzrostowy występuje również w Indiach, dlatego podjęto badania aerobiologiczne w celu określenia regionalnych różnic zawartości pyłku i zarodników w powietrzu.W artykule przedstawiono obecny stan badań aerobiologicznych prowadzonych w latach 2001–2015 w Indiach, ze szczególnym uwzględnieniem zawartości alergenów pyłkowych. Badania te potwierdzają znaczny udział alergenów pyłkowych w aeroplanktonie. Analizowano również korelację pomiędzy zawartością alergenów pyłkowych w powietrzu a danymi dotyczącymi hospitalizacji pacjentów, u których wystąpiły symptomy alergii. W regionach Indii północnych do alergenów pyłkowych należą Holoptelea integrifolia, Amaranthus spinosus, w regionach południowych Sorghum vulgare, Pennisetum, Gynandropsis gynandra, Parthenium hysterophorus, Dolichandrone platycalyx, w regionach zachodnich Parthenium hysterophorus, na obszarach centralnych Cynodon dactylon, Cenchrus ciliaris, a w regionach wschodnich Acacia auriculiformis, Cleome gynandra, Catharanthus roseus, Phoenix sylvestris, Areca catechu i Lantana camara. W okresie kwitnienia roślin produkujących pyłek alergiczny oraz tuż po tym okresie, wystąpiła znaczna korelacja pomiędzy wskaźnikiem hospitalizacji z powodu problemów zdrowotnych związanych z alergiami oraz zawartością alergenów pyłkowych w powietrzu. Stwierdzono, że pyłek gatunków z rodziny Poaceae jest dominujący na całym obszarze Indii. W badaniach immunobiochemicznych określono alergenny białkowe występujące w pyłku dominujących gatunków. Wykazano istnienie podobnych epitopów oraz homologię głównych białek alergennych, białka Cat r1 pochodzącego z Catharanthus sp. oraz białka Par j 1 pochodzącego z Parietaria judaica. Identyfikacja alergenów pyłkowych, określanie epitopów dominujących ziaren oraz wiedza o możliwej reaktywności krzyżowej alergenów ma istotne znaczenie kliniczne w zakresie zapobiegania, diagnozowania i leczenia chorób alergicznych w Indiach.

Opis:
Tinchuley (Latitude: 26.89748 N, Longitude: 88.23268 E) is a remote hamlet located close to Darjeeling which can be reached through a drive of 32 kilometers. Takdah Cantonment (Latitude: 26.89745 N, Longitude: 88.23265 E) is a settlement located in Darjeeling district, West Bengal, India. It is one of the upcoming tourist centers of the Darjeeling hills, around 4 km. from Tinchuley. The winding roads, tall pine and fir trees, intruding packs of cloud and warm and hospitable people makes it an ideal destination for people looking to escape from the hectic lifestyle of the city. The main objective of the present research work was to construct the social, environmental, cultural and economic framework of Tinchuley and Takdah Cantonment area and to highlight the proposals for sustainable management policies of those ecologically sensitive zones. The study was done in May, 2014 by visiting Tinchuley and Takdah and the information was gathered through field survey and direct contact with common people and authorized centers of the regions. Surveys on the agriculture, horticulture, livestock, water management, education, culture, health, waste management, transport and biodiversity were done in these areas. Tinchuley and Takdah have become the prominent tourist spots of West Bengal for pleasure trips, biological and geographical excursions and medical research works. In spite of getting so much attention in the recent time, the areas are not adequately developed. There is an urgent need for implementing sustainable management systems in the areas for the betterment of the socio-environmental structures. Some of the possible management strategies have been suggested for maintaining the social, environmental, economic and ecological balance of the regions.

Opis:
Catharanthus roseus G. Don. (CR) or periwinkle plants are widely grown/cultivated as garden plants in the tropics and subtropics. In spite of its predominantly entomophilous nature, CR pollen had been reported to be airborne and allergenic. The objective of this study was to discover the seasonal changes of CR pollen concentration in air, to determine its potential to cause respiratory allergy and to analyze its allergenic components. A 2-year aerobiological survey was conducted with a Burkard 7-day sampler in an agricultural farm in the suburban zone of Calcutta city where CR pollen was found to be almost perennial with 3.6-5.4% contribution to the aeropollen load. Skin prick test was conducted on 282 respiratory allergic individuals living within a 15 km radius of the study area. 29.8% of them were positive to CR pollen. Among them, 80.9% were directly involved in gardening. The whole pollen extract was subjected to gel fi ltration in a Sephacryl S-200 column. Among 5 eluted fractions, fraction I showed optimum IgE-reactivity in ELISA-inhibition. The fraction I shows 4 protein components in SDS-PAGE, within which 3 (40-66 kD molecular mass) were found to be IgE-reactive in immunoblotting using patient sera. It can be concluded that CR pollen can trigger IgEmediated respiratory allergy in the people living in close proximity.

Opis:
In this paper, we extended previous studies of cooperating autonomous robots to include situations when environmental changes and changes in the number of robots in the swarm can affect the efficiency to execute tasks assigned to the swarm of robots. We have presented a novel approach based on partition of the robot behavior. The sub-diagrams describing sub-routs allowed us to model advanced interactions between autonomous robots using limited number of state combinations avoiding combinatorial explosion of reachability. We identified the systems for which we can ensure the correctness of robots interactions. New techniques were presented to verify and analyze combined robots’ behavior. The partitioned diagrams allowed us to model advanced interactions between autonomous robots and detect irregularities such as deadlocks, lack of termination etc. The techniques were presented to verify and analyze combined robots’ behavior using model checking approach. The described system, Dedan verifier, is still under development. In the near future, timed and probabilistic verification are planned.
W artykule opisano kontynuację wcześniejszych badań dotyczących współpracy autonomicznych robotów wewnątrz budynku. Obejmują one obejmują sytuacje, w których zmiany środowiska i zmiana liczby robotów w roju mogą poprawić lub pogorszyć efektywność wykonywania zadań przypisanych do roju robotów. Zaprezentowaliśmy nowatorskie podejście z wykorzystaniem dzielenia zachowań robota na zachowania składowe. Poddiagramy opisujące kładowe podmarszruty pozwoliły nam modelować zaawansowane interakcje między autonomicznymi robotami w oparciu o ograniczoną liczbę kombinacji zachowań, unikając eksplozji kombinatorycznej przestrzeni osiągalności. Opisano systemy, dla których możemy zapewnić poprawność interakcji robotów i zaprezentowano techniki weryfikacji i analizy zachowań połączonych robotów. Diagramy podzielone na partycje pozwoliły nam modelować zaawansowane interakcje pomiędzy autonomicznymi robotami i wykrywać nieprawidłowości, takie jak zakleszczenia, brak terminacji itp. Przedstawiono techniki weryfikacji i analizy złożonych zachowań robotów za pomocą techniki weryfikacji modelowej. Opisany system weryfikacji, Dedan, jest wciąż rozwijany. W niedalekiej przyszłości planowana jest weryfikacja z czasem rzeczywistym i probabilistyczna.

Opis:
India is a rich cultural country in which diverse cultural and religious festivals are organized. Idol is an image of a god which is used as an object of worship. After worshipped, these idols are immersed into water bodies. Idols are constructed by plaster of paris, clay, cloths, small iron rods, bamboo and decorated with different paints such as varnish, water colors etc. which can lead to significant alteration in the water quality after immersion. Paints which are used to colour these idols contains various heavy metals such as Mercury, Cadmium, Arsenic, Zinc, Chromium and Lead. Particularly, red, blue, orange and green colours contain mercury, zinc oxide, chromium and lead, which are potent carcinogens. Two heavy metals such as Lead and Chromium also add in the water bodies through Sindoor (a traditional red colored cosmetic powder, usually worn by married women and often used in the festivals). The floating materials released through idol in the river and lake after decomposition result in eutrophication, increase in acidity and heavy metal concentration. Heavy metal pollution caused by idol immersion can damage the ecosystem as it kills fishes, damages plants, blocks the natural flow of the water, causing stagnation. The effects of idol immersion on various water bodies of India like Bhoj wetland, Budhabalanga river, Ganges river, Hussainsagar lake, Kolar river, Sarayu river, Tapi river, Chhatri lake, north and west lakes of Bangalore and Yamuna river have been observed so far. Investigations were carried out to find out the effects of immersion of idols on water quality by collecting and analyzing the water samples from the immersion sites of the rivers. The samplings were done before the immersion, on the day of immersion and after the event and several parameters like Temperature, pH, Dissolved Oxygen, BOD, Dissolved CO2, Conductivity, Salinity, Alkalinity, TDS, Total Hardness, Chlorides etc. are estimated. Most of the studies found significant changes in the water quality parameters during and after immersions. Central Pollution Control Board has formulated guidelines on the practice of idol immersion in water bodies, which should be followed for controlling pollution.

Opis:
Ericales is an ancient eudicot order encompassing numerous species of economic and ornamental values. Despite several phylogenomic studies, the evolutionary relationship among certain families of this group remains uncertain. The present study assessed a multilocus species tree of Ericales based on 107 chloroplast genomes. The plastome derived microsatellite motifs were also simultaneously explored to check their dynamicity in corroboration of species phylogeny and systematics. In addition to resolving the usual hierarchy, the present phylogenetic analysis enabled to resolve the persisting lineage disparity with valid statistical support. Accordingly, divergence incongruences of Primulaceae, Ebenaceae, and Sapotaceae from earlier reports were reinstated in presently inferred phylogeny, which further supported the latest transcriptome-based relationship of the corresponding group. Various SSR motif characteristics emerged following the recognition of the evolutionary pathway. Numerical variation in tetranucleotide repeats showed even intraspecific or varietal differences in Camellia sinensis. Validation of plastome microsatellite-based polymorphism among the related taxa might pave the way for future phylogenetic and population studies of this economically important group.

Opis:
Arsenic (As) is a metalloid that causes severe water pollution due to its extravagant toxicity. Ceriodaphnia dubia, a freshwater crustacean, was selected as a model system to evaluate the degree of time and dosage dependent acute toxicity caused by pentavalent As [As(V)]. C. dubia were collected from a natural pond and treated with different concentrations of As(V) for 24 hours and 48 hours. For both 24 hours and 48 hours treatment periods, the mortality rates were increased significantly ( P< 0.05) with increase in As(V) concentrations. Simultaneously, it was also observed that As(V) - induced mortality in C. dubia also depended on the time of exposure to the metalloid. We propose this model as a low-cost technique towards rapid screening of water quality in relation to As contamination.

Opis:
Oryza sativa Linn. (rice) and Corchorus capsularis Linn. (jute) are the two major crops of the Bengal basin. Both rice and jute are generally grown in submerged flooded conditions, where arsenic bioavailability is high in soil. The consumers of the edible parts from both plants therefore face an inevitable source of exposure to arsenic, with consequent accumulation and toxicity. The objective of the study was to observe the in-vivo temporal variation of arsenic bioaccumulation in the different parts of O. sativa and C. capsularis. Rice plant specimens (Aman rice, Ratna variety) of different age groups (1, 2 and 3 months old) were analyzed in HG-AAS for absorbed arsenic content in different parts. The accumulation of arsenic remained significantly high in the initial phase of growth, but decreased with time. Amount of arsenic bioaccumulation followed the decreasing order: root > basal stem > median stem > apical stem > leaves > grains in all the three age groups of the rice plant samples. C. capsularis followed a trend of arsenic bioaccumulation similar to O. sativa. O. sativa had more accumulation potential than C. capsularis, but C. capsularis showed much higher efficiency of arsenic translocation in the above ground parts. This is the first ever report of time-dependent decrease in arsenic bioaccumulation in O. sativa and C. capsularis. The contamination level can reach the grain part in significant amount and can cause health hazards in more severely arsenic affected areas. Intensive investigation on a complete food chain is urgently needed in the arsenic contaminated zones for further risk assessments.

Opis:
Underwater Wireless Sensor Networks are deployed to explore the world under the water, measure different parameters and communicate the data to the surface, in the widespread applications. The main operating technology of these networks is the acoustic communication. The communication among the sensors and finally to the surface station requires a routing protocol. The sensors being battery limited and unfeasible to be replaced under the water requires an energy efficient routing protocol. Clustering imparted in routing is an energy saving technique in sensor networks. The routing may involve single or multi hop communication in the sensor networks. The paper gives a comparative study of the benchmark protocol multi-hop LEACH with the proposed Sensor Hop-based Energy Efficient Networking Approach (SHEENA) for the shallow as well as deep water in three dimensional Underwater Wireless Sensor Networks. The network energy model for the Underwater Wireless Sensor Networks is based among the different acoustic channel characteristics. The proposed approach is found to give better response.
