Exclusão digital, diferenças no acesso e uso de tecnologias de informação e comunicação: questões conceituais, metodológicas e empíricas
Authors: Knop Marcelo Ferreira Trezza
Published: April 2018

Este artigo destaca a relação desigual entre educação e trabalho, desencadeados por distintos acessos aos denominados bens generativos de valor; nesse caso, as tecnologias de informação e comunicação. Dessa forma, como principais resultados alcançados, destaca-se que a exclusão/inclusão digital é um fenômeno complexo e multifacetado, ou seja, que vai muito além que disponibilizar computadores com acesso à internet a determinados atores sociais. Essas diferenças de oportunidades estão relacionadas a diversos fatores, tais como, a falta de infraestrutura física e de TIC adequada, ou seja, laboratório com hardwares, softwares e periféricos em perfeito funcionamento e atualizados, como também a conexão ou banda de internet (mostrando que a disponibilização desses meios, por si só, não diminuiu esse distanciamento).   Relaciona-se também a impossibilidade de acesso e uso contínuo das tecnologias de informação e, consequentemente, das ferramentas aprendidas nos encontros (pois, não há o desejo das instituições pesquisadas em ampliar esse acesso e incluí-los no dia-a-dia dos alunos); aos tipos de usos das tecnologias de informação pelos beneficiários do projeto, nas horas de aula e fora dela (principalmente o grande interesse pelas redes sociais virtuais e por jogos); e aos diferentes níveis de aprendizado verificados durante os cursos, com destaque para tipos diferenciados de interesse (mesmo por jovens pertencentes ao mesmo grupo social).

Published: April 2018

The campaign against drug abuse is fought by all countries, most notably on ATS drugs. The technical limitations of the current test kits to detect new brand of ATS drugs present a challenge to law enforcement authorities and forensic laboratories. Meanwhile, new molecular microscopy imaging devices which allowed mankind to characterize the physical 3D molecular structure have been recently introduced, and it can be used to remedy the limitations of existing drug test kits. Thus, a new type of 3D molecular structure representation technique should be developed to cater the 3D molecular structure acquired physically using these molecular imaging devices. One of the applications of image processing methods to represent a 3D image is 3D moments and moment invariants. However, since there are currently no repository or database available which provide the drugs imaging results obtained using these recent imaging devices, this paper proposes to construct the simulated 3D drugs molecular structure to be used by these 3D moments and moment invariants techniques. The drugs molecular structures are obtained from pihkal.info for the ATS drugs, while non-ATS drugs are obtained randomly from ChemSpider database.

Development and validation of a High performance liquid chromatography- Mass spectrometry method for 17a-methyltestosterone in Aquatic water systems
Authors: Marwah Ashok , Nianzu Xu , Marwah Padma , Barry Terence P.
Published: April 2018

17a-Methyltestosterone is used as feed additive to manipulate the gender of fish for aquaculture. Earlier a simple, yet specific and robust validated high performance liquid chromatographic method has been developed for the determination of 17a-methyltestosterone in fish feed. The present work describes a highly sensitive and robust Liquid Chromatography-Mass Spectrometry method for the quantitation of 17a-methyltestosterone in aquatic water systems using 17â-hydroxy-3â-methoxyandrost-5-en-7-one as internal standard. The method was validated in the concentration range of 0.2 to 25 ng of 17a-methyltestosterone on column leading to a limit of quantitation of 0.08 ppb or 0.08 mg/L in water, and has potential to increase the limit of detection and quantitation by an order of magnitude, if required.
Behavioural shift of estuarine mudcrab as biomarker of arsenic exposure in Sundarbans estuary of West Bengal
Authors: Saha Sanjib , Ray Mitali , Ray Sajal
Published: April 2018

Mudcrab Scylla serrata (Crustacea: Decapoda) in an ecologically and economically important species of Sundarbans Biosphere Reserve was studied for its behaviour under the exposure of toxic arsenic - a common xenobiotic of this area. The behavioural profile of aquatic animals exposed to diverse toxicants are considered as an index to estimate the degree and nature of stress experienced by the animals both in nature and in experimental conditions. Present investigation involved study of selected behavioural shift of S. serrata under the sublethalconcentrations of 1, 2 and 3 ppm of sodium arsenite for 1, 2, 3 and 4 days in controlled laboratory condition. Exposure to arsenic resulted an appearance of selected abnormal behavioural manifestation including tendency of avoidance, hypersecretion of mucoid element and release of excess excretory products. Toxin induced alteration of studied behaviour is indicative to possible shift in the overall physiological functions and biological activities of this important species in its natural habitat. Chronic exposure to 3 ppm of sodium arsenite for 30 days may lead to decline this economically important species in Sundarbans Biosphere Reserve.

The present study was carried to investigate the noise level at four different locations of Haridwar viz. Singh Dwar, Rishikul, Chandi ghat and Har Ki Pauri during Kumbh Mela 2010. During normal days maximum noise levels were recorded at Chandi ghat i.e. 87.11±0.45 dB (A) in the evening hours and minimum noise levels were recorded at Har Ki Pauri i.e. 60.8±0.89 dB (A) in the morning hours. While during festival days maximum noise levels were at Har Ki Pauri i.e. 88.4 ± 1.65 dB (A) in the evening respectively and Rishikul the least being 54.93±0.53 dB (A) in the morning hours. Noise levels in all the areas were found to be above the ambient noise standard. These high noise levels may have induced headache, annoyance, lack of concentration and other varied effects on human health.
Isolation, purification, characterization and applications of serine protease from Bacillus megaterium
Authors: Rajesh T. S. , Deepa Deepa , Divya Divya , Mahesh M. , Somshekar Somshekar
Published: April 2018

Bacillus megaterium isolated from poultry farm soil was identified by standard biochemical tests and screened for the production of serine protease. Production of serine protease was done using 5 different medias by varying the type of amino acid added. The purification was done by salt precipitation, dialysis and DEAEcellulose ion exchange chromatography. The proline containing media obtained the highest fold purification out of the five different medias (leucine, lysine, proline, tryptophan and methionine cotaining media). The enzyme showedan optimal activity at the temperature 37°C and the pH 6 which are known as its optimum temperature and pH respectively. The enzyme was proved as a Mn2+ dependent serine protease as it was activated by Mn2+ ions and inhibited by PMSF. The molecular weight of the enzyme was determined by SDS-PAGE technique as around 30kDa. It showed an excellent detergent activity on the blood stains and a very good stability in presence of locally available detrgents. The enzyme acted on the keratin protein of the chicken feather and showed a degrading capacity on the protein. So it was proved that the recently studied serine protease has a keratinase activity also. From these datas I conclude that the protease isolated from Bacillus megaterium is a Mn2+ dependent serine protease which has both keratinase and detergent activity.
A review on systematic study of cellulose
Authors: Gautam S.P. , Bundela P.S. , Pandey A.K. , Jamaluddin Jamaluddin , Awasthi M.K. , Sarsaiya S.
Published: April 2018

This review attempts to bring together basic and systematic information which has been gathered on cellulose structure, types, principally that of native cellulose, over the last few decades. Even though advances have been made in the field of crystallography, powder crystallography cannot yield a definitive cellulose structure and single crystal diffraction is not possible due to the lack of suitable crystals. Knowledge obtained on the biosynthesis of native cellulose and on the polymorphy of cellulose and its derivatives help our understanding of ultrastructure. Many inconsistencies between early crystallographic studies of native cellulose have been clarified by the discovery that two polymorphs (á and â) of cellulose I exist. Models of the possible ultrastructural arrangements within native cellulose have been put forward over the decades; with advancement in technology, computer simulations of small and large systems are being created to test the viability of these ultrastructural models. It is hoped that this review will aid in the understanding of the complexity and uncertainties that still exist in this subject.
Transformation of 17a-methyltestosterone in aquatic-sediment systems
Authors: Barry Terence P. , Marwah Padma , Marwah Ashok
Published: April 2018

Two sediment samples that differed with respect to total organic carbon and texture (“sand” and “clay”) were exposed to radio inert 17a-methyltestosterone (MT) or [14C]-radiolabeled 17a-methyltestosterone (14C-MT), under both aerobic and anaerobic conditions, for up to 56 days, to characterize the fate of MT in the aquatic environment. Radio inert MT was quantified by a highly sensitive liquid chromatography/mass spectrometry (LCMS) method and radioactive MT was quantified by HPLC using an in-line flow liquid scintillation counter (LSC). Thedata suggest that MT entering the aquatic environment is converted into metabolites that become tightly associated with the sediment. Half-lives for MT dissipation in the sediment systems ranged from 2-9 days, depending on the sediment type and the presence of oxygen. Sediment type had little effect on MT dissipation. The mineralization of MT under aerobic conditions was low (<9% conversion of MT to CO2).
Population dynamics and conservation management of Himalayan mahseer (Tor species) in riverine aquatic ecosystem in Garhwal region of Uttarakhand (India)
Authors: Malik Davendra Singh
Published: April 2018

The mahseer, an Indian carp (Tor species) known as ‘Sport fish’ continues to be decimated by the large scale natural and anthropogenic factors and categorized as threatened fishes in India. The present research data revealed that total species richness of 33 and 24 number of fish species were identified in river Ganga and Yamuna respectively. The size group of mahseer (400-460mm) recorded as a dominant size of catch composition and contributed about 36.8% and 42.6% based on different sampling sites in river Yamuna and Ganga respectively. The populations of Tor tor, T. putitora have shown a decreasing trend at very alarming rate and influenced the sex ratio, maturity size and natural breeding condition. Only 12.5 to 14.8% mahseer female brooders have shown maturity phase or emenable to release ova during particular breeding seasons. The fecundity of mature female fish brooders ranged from 2500-4500 no. of eggs during July-August. The current status of mahseer fishery may be attributed to the over exploitative nature in riverine system. ‘In situ and Ex-situ” breeding techniques should be practiced for enhancement of viable population size of mahseer species to restore the genetic loss under mahseer conservation programme in aquatic ecosystem of Himalayan region.
Fate of some heavy metals in soils: a review
Authors: Orhue Ehi Robert , Frank Uzu Ogbonnaya
Published: April 2018

This review revealed that heavy metals are naturally components of the soil orchestrated by weathering processes and that the abundance of these metals in our soil environment nowadays is due to numerous anthropogenic activities. These heavy metals are in two major categories namely the essential and non- essential ones. The essential heavy metals are needed in trace amount by living things for their physiological processes. But at higher concentration, it is hazardous in plants and animals. On the other hand, the non essential ones aredangerous to plants and animals even at low concentrations. This write-up further showed that soil pH, organic carbon, available P, oxides, effective cation exchange capacity, moisture content, oxidation-reduction state of the metals, ion exchange and sorption capacity of the metals are some of the soil factors influencing the fate and availability of the heavy metals. At lower levels of these soil factors, heavy metal ions are rendered free in the solution thereby making them available to plant and underground water. However, the most prominent soil factor influencing availability of these metals is the Soil pH. Raising some of these soil factors to appropriate levels have been discovered to reduce the availability of the heavy metals to mankind.

Authors: Orhue Ehi Robert , Ekhomun Akhere Mathew
Published: April 2018

The greenhouse and field trials were conducted at the University of Benin, Benin City, Nigeria to determine the influence of Cd on the growth, dry matter yield and nutrient uptake by fluted pumpkin (Telfairia occidentalis). Four levels of Cd(NO3)2 treatments namely 0, 50, 100, 200 mg per 5 kg soil equivalent to 0, 20, 40, 80 kgha-1 were used in the greenhouse and field trials respectively. The completely randomized and randomized complete block experimental designs were used in the greenhouse and field trials respectively. Results indicated that increased application of Cd decreased the height, number of leaves, leaf area, stem girth and dry matter yield of the plant. The nutrients content and uptake also decreased with the increase in the supply of the Cd. Higher Cd concentrations and uptake were recorded in the root of the treated plants when compared to the control treatments. The nutrients and oxides components of the soil decreased at various levels of the Cd application. These decrease in soil nutrient components were however not consistent. However, the Cd content of the soil increased with increased Cd treatments.

Authors: Kumar Sunil , Kumari Priyanka , Devi Shoma
Published: April 2018

The purpose of this study was to know the hepatotoxicity of ethanol in laboratory rats Rattus rattus and to observe the individual and combined phytotherapeutic role of five herbs viz. Arctium lappa, Curcuma longa, Piper longum, Plumbago zeylanica and Terminalia chebula through biochemical and histopathological parameters. Ethanol is commonly used as solvent, pharmaceutical, drugs and alcohol abuse. Lipidperoxidation, glutathione content, urinary hydroxyproline, collagen and histopathological studies showed hepatotoxicity of 1 ml/kg bodyweight dose of ethanol and protective role of 100 mg/kg body weight dose of herbs. Histopathological changes observed in the liver of rats after ethanol treatment showed hepatitis, collagenesis, fatty infiltration, sclerosis, perilobular necrosis, cytoplasmic degeneration, enlarged bile canaliculi, hydropic degeneration, focal necrosis, binucleated hepatocytes and nuclear degeneration. Mild cytoplasmic degeneration, necrosis, collagenesis and hepatocytes regenerations were observed in rats treated with same dose of ethanol and herbal combination.Ethanol treatment decreased the glutathione content, increased tissue malondialdehyde and collagen content, thus causing tissue injury and liver collagenesis. Urinary hydroxyproline level and biochemical parameters also showed the protective role of herbs against ethanol induced toxicity. Herbal combination i. e. 100ml/kg body weight from the mixture of five herbs given orally was found more effective than their individual role. Herbs and plants contain aromatic substances, secondary metabolites, alkaloids and polyphenols which act as antioxidant thus showing protective role.

Authors: Bhagabati Kalyanee Sharma , Sarma Hemen
Published: April 2018

The present study was carried out to evaluate the effect of indiscriminant use of common pesticides especially insecticide on the population of soil micro flora in cultivated soil of Indian rice field agro-ecosystems. Endosulfan and Dichlorvos @ 1ml/l (normal dose) did not show any adverse effect on soil micro flora; but a high dose 2ml/l showed a negative effect. On the other hand Carbofuran @ 9 kg/acre (normal dose) and 12kg/ acre (high dose) showed an adverse effect on the growth of actinomycetes, bacteria and fungi. The important findings of the present study is that the effect on microbes by applying insecticides reflects the ecological imbalance of microbes in cultivated soil and hamper the microbial equilibrium to some extent. The study focused that the uses of the pesticides as a plant protection agent occasionally hamper the growth of soil micro flora in cultivated rice field.

Published: April 2018

The present study was carried out to investigate the effect of arsenic trioxide on the DNA and histomorphology of testis, liver and kidney of Swiss albino mice, Mus musculus. Oral administration of arsenic trioxide induced DNA damage in the testis, liver and kidney marked by light pink staining of nuclei after Feulgen’s reaction with reduced fine chromatin. Simultaneously severe histological changes were noted like distortion of seminiferous tubules, disorganization of spermatogonia, spermatocytes and spermatids with cytoplasmic vacuolization and nuclear pycnosis in testis. There was almost disappearance of sinusoids due to disruption of hepatic plates, inflammatory cellular infiltration around central veins and cytoplasmic vacuolization in hepatocytes with large irregular nuclei in liver of treated mice. Disorganized glomeruli with distorted Bowman’s capsules and mild to severe multifocal cloudy and hydropic degeneration with necrosis of tubules were observed in the kidney of treated mice. Inference drawn from the study indicated that arsenic induced both genotoxic histotoxic lesions.

The buds, which started growing, were transferred to solidified MS basal medium with 4 mg/l BAP and 15 mg/l AdS to achieve about three fold multiplication. Single shoots or 2-shoot clusters did not survive and therefore all the experiments were conducted with a cluster of minimum 3-shoots. The rooting was found difficult. Three hormones viz. IAA, IBA and NAA with a concentration of 1, 3 and 5 mg/l were used in various combinations for rooting. Out of the total 9 treatments, only 20% rooting was found only in one treatment, namely in the medium with 5 mg/l indole butyric acid (IBA).

Published: April 2018

The annual maximum discharge data of six gauging sites have been considered for L-moment based regional flood frequency analysis of Tripura, India. Homogeneity of the region has been tested based on heterogeneity measure (H) using method of L-moment. Based on heterogeneity measure it has been observed that the region consist of six gauging sites is homogeneous. Different probability distributions viz. Generalized extreme value (GEV), Generalized Logistic (GLO), Generalized Pareto (GPA), Generalized Normal (GNO), Pearson Type III (PE3) and Wakebay (WAK) have been considered for this investigation. PE3, GNO and GEV have been identified as the candidate distributions based on the L-moment ratio diagram and ZDIST -statistics criteria. Regional growth curves for three candidate distributions have been developed for gauged and ungauged catchments. Monte Carlo simulations technique has also been used to estimate accuracy of the estimated regional growth curves and quantiles. From simulation study it has been observed that PE3 distribution is the robust one.

Aspergillosis is an acute chronic and rapidly fatal disease which is not contagious. Invasive Aspergillosis is often found in severely immuno-suppressed patients, and is characterized by invasion of blood vessels which can result into dissemination to other organs. Aspergilloma is a fungal ball that develops in previous cavitary lung lesions. Essential oils and their volatile constituents have been used as antifungal, anti-infectious and antimicrobial agents. Inhalation of vapours of the essential oils kill invaders attached to the inner respiratory lining and worksynergistically with the body defences. In this study, 16 essential oils were used against Aspergillus niger and A. fumigatus of which about 14 oils proved to be effective. Results showed that the most effective oils against both Aspergillus species were found to be of Cinnamomum zeylanicum (Cinnamon), Syzygium aromaticum (Clove), Carum carvi (Caraway), Cymbopogon citrates (Lemongrass), Foeniculum vulgare (Fennel) and Myristica fragrans (Nutmeg). Moderately effective oils were of Gaultheria procumbens (Wintergreen), Pinus palustris (Turpentine), Sesamum indicum (Sesame), Trachyspermum ammi (Ajowain) and Origanum vulgare (Oregano). The oils of Lavandula augustifolia (Lavender), Elletaria cardamomum (Cardamon) and Cymbopogon nardus (Citronella) showed minimum activity. Azadirachta indica (Neem) and Linum usitatissimum (Linseed) showed no activity giving no inhibition zones.

Antennal sensilla of head of poultry shaft louse, Menopon gallinae (Phthiraptera, Insecta, Menoponidae, Amblycera)
Authors: Arya Surman , Singh Suneel Kumar
Published: April 2018

Phthirapteran ectoparasites (lice) are very small arthropodan creature which spend their life on different mammalian and avian host body. Many morphological features of these tiny creatures are not visible under simple microscopic study and hence scanning electron microscopic (SEM) study is required for specific details. Antennal sensillum is also one of the special features located on anterior part of the head of the louse. The present study on the sample specimen of poultry louse, Menopon gallinae (Phthiraptera : Amblycera) showed presence of a small, ovoid scape and pedicel (broad cup-like structure having narrower base) seen in antennal sensilla under SEM. In addition to sensory setae, sense organ was present on terminal segment. Tuft organ contain 6/7 small peg like structure. Pit organ was also visible at the sub-terminal area of fourth segment. Presence of any structure resembling coeloconic chaemo-receptor was not observed on any flagellar sub-segment of M. gallinae.

Published: April 2018

The present paper is aimed towards the assessment of heavy metal contamination of agricultural soil due to irrigation with contaminated ground water affected by textile industrial effluents at Panipat city in India. Samples of ground water and irrigated soils from textile industrial area were analyzed for various heavy metals, viz. Mn, Ni, Fe, Cu, Cd, Pb and Zn, using Atomic Absorption Spectrophotometry. Metal transfer factors from ground water to irrigated agricultural soil and from soil to ground water were calculated for heavy metals. The findings deal with the distribution of heavy metals in ground water of industrial area and irrigated agricultural soil. Transfer factors for heavy metals from effluent to ground water were observed to be 0.436, 1.180, 6.461, 2.401, 2.790, 3.178 and 0.634 for Cd, Cu, Fe, Mn, Ni, Pb and Zn respectively. These were found to be very high from ground water to agriculture soil due to the natural shale value of heavy metals in soil system. Thus, untreated industrial effluents can cause an environmental threat to ground water resources and affects soil quality and agricultural plant productivity.

Tropical forests are one of the richest landscapes in terms of its richness, diversity and endemicity. The present study was carried out in the Central Western Ghats: one of the hottest hotspot of biodiversity. The aim of the study was to compare floristic diversity in tropical wet evergreen forest between northern and southern parts of Western Ghats of Karnataka. Kodagu district in southern part and Uttara Kannada district in northern part was chosen to assess the same, as these two districts cover highest forest cover in the Western Ghats of Karnataka. In each district all the evergreen forests were sampled with 1000 m X 5 belt transacts. Totally 22 such samplings were done both southern and northern part of Western Ghats. In each of these transacts all the trees measuring e” 30 gbh were enumerated and botanically identified to the species level and the same was used for computation of diversity indices. The richness and diversity was comparatively higher in southern part compared to northern part of Western Ghats, where as the richness of threatened tree species was comparatively higher in northern part of Western Ghats. In addition to the species richness and diversity, the paper also deals with the dominant tree species and families in both the region.

Published: April 2018

The effect of different wood flour sizes on strength and dimensional properties of wood-plastic composites were examined. Wood flour of different particle sizes viz; 1.00mm, 2.00mm and >2.00mm were compounded with recycled low-density polyethylene (LDPE) at different wood/plastic ratio of 1: 1, 2: 3 and 3: 2. The results obtained showed that wood flour size > 2.00mm has the highest MOR and MOE values of 1.206N mm-2 and 2484.72Nmm-2 while wood flour size of 1.00mm had the lowest MOR and MOE values of 0.505Nmm-2 and 2195.89Nmm-2 respectively. Also the results of the physical properties showed that wood flour size of 1.00mm had the lowest thickness swelling percentage with mean values of 0.28% and 2.08% while water absorption percentage has mean values of 0.91% and 10.58% after 2 hours and 24 hours of water immersion respectively. It was observed that wood flour size of 2.00mm and particle size >2.00mm had the highest thickness swelling and water absorption percentages. This showed that strength properties of wood plastic composites increased with increased particle sizes whereas its dimensional properties increased with decreased particle sizes. The results of analysis of variance carried out on mechanical and physical properties showed that particle sizes and wood/plastic ratio had a significant effect on the mechanical and physical properties of wood plastic composites (p 0.05).
Impact of dietary glutathione on hematological indices in rats poisoned with hexavalent chromium
Authors: Kumar Ajay , Kumar Alok
Published: April 2018

The effects of dietary glutathione against chromium induced hematological indices were studied in rats, Rattus rattus albino. Supplementation of glutahione to the diet of chromium fed rats, elevated significantly percent hemoglobin (40.4%), number of red blood corpuscles (48.7%), plasma corpuscular volume (43.4%) and mean corpuscular volume (37.1%) which were inhibited in chromium poisoned rats. However, no marked elevation was noticed in number of white blood corpuscles and total proteins. Intake of glutahione checked the accumulation of glucose, cholesterol, tryglcerides, phospholipids and bilirubin in chromium treated rats. Chromium intoxication significantly increased the activities of transaminases (p<0.001) and dehydrogenases (p<0.01/p<0.001) which declined by supplementation of gltathione which also restored the chromium inhibited activity of alkaline and acid phosphatase. Specific reasons for these pharmacoticological aspects of glutathione have also been discussed.
