Résumé :

Fluvial processes such as bank erosion plays an important role to change the channel stability of the Torsa River in the downstream region. The present study was focused on stream stability assessment of the Torsa River. The study area is situated between the downstream of the Jaldapara Reserve Forest and confluence of Kaljani River. Data of different parameters about 64 bank segments of the Torsa River were prepared using the field work techniques for assessing the stream bank conditions using lateral, vertical and overall reach stability models. The individual results of BEHI and NBS ratings show that out of 64 bank segments only 35 and 19 bank segments classified in higher categories. Overall lateral stability analysis shows that most of the sample bank segments are in an unstable condition. All bank segments are vertically unstable and degrading. Overall reach stability analysis shows widespread instability. BEHI and NBS results are almost similar for most of the bank segments and therefore, BEHI and NBS can be suitable bank erosion hazard predictive models in the study for channel stability analysis.

Résumé :

Abstract The varied physiography, incidences of high seasonal discharge, influences of neo-tectonic activity and the young geological foundation with less consolidated cohesive and non-cohesive sediment have left the Himalayan foreland basin a formidable ground, where silt-laden rivers tend to migrate frequently. A set of maps prepared after 1764, space photographs captured in 1970 and current satellite images from 2015 and 2017 were studied to reconstruct the fluvial dynamics of the Torsa River on the foreland basin of Sikkim-Bhutan Himalaya considering a time span of nearly 250 years. Evidence collected from colonial literature, the above-mentioned satellite images and a field survey, were combined to verify results taken from the old maps used as the base of the study. The application of satellite remote sensing and analysis of the topographic signatures of the palaeo-courses in the form of the palaeo-levee, abandoned courses and ox-bow lakes were the major operational attributes in this study. As a consequence of the channel migration of Torsa River since 1764, the historical floodplain of Torsa has been topographically marked by beheaded old distributaries, a misfit channel system and the presence of abandoned segments. Morphometric changes in the old courses, major flood events and neo-tectonic activity guided an overall trend of channel migration eastwards and has led to a couple of channel oscillation events in the Torsa River over the last 250 years. The mechanism of the avulsion events was thoroughly driven by sedimentation-induced channel morphometric changes and occasional high discharge.

Résumé :

A Gram-negative, rod-shaped, nickel-resistant bacterium, designated as strain NiVas 114', was isolated from waters of Torsa River in Hasimara, West Bengal, India. The strain NiVasl 14 possessing inducible nickel resistance can tolerate maximally 10mM nickel chloride. Southern blot assays of genomic DNA of NiVas 114 using probe(s) generated from known nickel resistance determinants (cnr/ ncc/ nrel nerí nir). under conditions of low stringency, produced no detectable signal except for cnrA gene of Ralstonia metallidurans CH34 (formerly Alcaligenes eutropha CH34) in which weak hybridization signal occurred. Based on 16S rRNA gene sequence similarity, strain NiVas 114 was identified as a member of y Proteobacteria, and the nearest phylogenetic relatives are Enterobacter hormaechei (98.6-98.5%) and Enterobacter cloacae (97.5-98.2 %). In the phylogenetic trees constructed with nucleotide sequence of 16S rRNA gene, hsp60 gene and rpoB gene, strain NiVas 114" clustered with the subspecies of Enterobacter hormaechei. The strain showed DNA-DNA relatedness of 60 -63% with Enterobacter hormaechei subsp hormaechei, Enterobacter hormaechei subsp. oharae, Enterobacter hormaechei subsp. steigerwalti Enterobacter cloacae subsp. cloacae and Enterobacter cloacae subsp. dissobvens. The isolate NiVas 114 differed from the nearest phylogenetic relatives in terms of number of phenotypic characteristics. The G+C content of the genomic DNA of the isolate was 59.5 +0.4 mol %. The predominant cellular faty acids of the isolate are C160, Summed feature 3 (comprises C16wTel 15 io 201) and C 18 w7ei hydroxy fatty acids are found in minor quantities. Thus, on the basis of biochemical characteristics, fatty acid profiles, DNA-DNA relatedness and phylogenetic analysis, the isolate was recognized as a novel species of Enterobacter. for which the name Enterobacter nickellidurans sp. nov. is proposed with the type strain NiVas 114' (= LMG 23000 = CcUGSO594"= JCM13045").

Résumé :

A Gram-negative, rod-shaped, urea-dissolving and non-spore-forming bacterium, designated strain NiVa 51T, was isolated from water of the River Torsa in Hasimara, Jalpaiguri district, West Bengal, India. On the basis of 16S rRNA gene sequence similarity, strain NiVa 51T was shown to belong to the γ-Proteobacteria and to be related to Serratia marcescens subsp. sakuensis (98·35 %) and S. marcescens subsp. marcescens (98·30 %); however, strain NiVa 51T exhibited only 43·7 % similarity to S. marcescens by DNA–DNA hybridization. The G+C content of the genomic DNA of the isolate was 60 mol%. Both biochemical characteristics and fatty acid analysis data supported the affiliation of strain NiVa 51T to the genus Serratia. Furthermore, strain NiVa 51T was found to utilize urea as nitrogen source. The results of DNA–DNA hybridization as well as physiological and biochemical tests allowed genotypic and phenotypic differentiation of strain NiVa 51T from recognized Serratia species. Strain NiVa 51T therefore represents a novel species, for which the name Serratia ureilytica sp. nov. is proposed, with type strain NiVa 51T (=LMG 22860T=CCUG 50595T).

Résumé :

Tribal people having common issues related to poor health indicator, high morbidity and mortality level and lack of proper health care services (Govt. of India, Ministry of Tribal Affairs, 2013). This paper aims to examine socio-economic conditions of tribal people among totopara village community and to find out factors affecting health status and their access to health care facilities. Totopara which is a small village under Madarihat police station of the district of Alipurduar which lies between 89°20’ East latitude and 26°50’ North longitude. The Totos have resided at the foothills of the Himalaya closed to Bhutan in a small village named Totopara in Alipurduar district of West Bengal since time immemorial. The Totopara is administratively under Ballalguri Gram Panchayat (JL No-33) which lies on the western bank of Torsa River. Their marginalisation is an underlying cause of poor health limiting their opportunities to present their own perspectives of their situation. It is not a surprising fact that the incidence of health-related issues is found more among the toto tribal community because of their biophysical attributes and the state of vulnerability which further makes them more vulnerable group among the tribal people. The acute problem of them is examine in the research work also. The problems of their health are listed. There is a need of long-term policy intervention to promote better living standards and better reproductive health through educational development. It is high time and states should act swiftly to assess the needs, priorities of their own tribal population and set goals, targets to achieve the same through proven public health strategies.

Résumé :

In the 17th century the development of the steppe outskirts of the Russian state witnessed settling in the middle course of the Seversky Donets River. The territory was developed by Russian military settlers and settlers from the Dnieper region – Cherkasses. Their number was increasing since the second half of the 17th century. During this period, a number of fortified settlements were built in the region, the most important of which were connected by the Thora defensive line. Later the area received not fortified settlements. The southernmost point of this region was the Bakhmut fortress founded in 1701. The development of the territories south of this fortress began in the second half of the century. It marks the beginning of the new stage in the development of the Russian people of the steppes of the Northern Azov region. Archaeological research of these monuments located in the north of Donbass was conducted at the turn of 20th–21st centuries. The explorations found undisturbed remains of the Torsa defensive line of the 17th century, and revealed a number of unfortified settlements. Archaeological excavations were carried out at key sites. The key sites include Sviatogorsk monastery as one of the earliest settlements in this area. More basic research was carried out at Kazachya Prystan (Raigorodok), Tor (Slavyansk), and a settlement located in the Yavor tract. These works helped obtain a large amount of archaeological material that describes different aspects of economic and cultural life of the people who were developing the Russian border steppes in the 17th–18th centuries. These people are direct ancestors of the current inhabitants of the settlements located in the north of the Donetsk region.

Résumé :

Bogotá es la capital de Colombia y cuenta con cuatro ríos que la atraviesan de oriente a occidente: Tunjuelito, Fucha, Salitre y Torca, los cuales se han subdivido en cuatro tramos para su estudio, por lo que se planificó la metodología para conocer la calidad hídrica del tramo 3 del río Fucha con base en el Índice de Calidad General para Aguas Superficiales (ICACOSU), en relación con el cumplimiento de los objetivos de calidad hídrica establecidos en la Resolución 5731 de 2008 para los ríos de la ciudad. Para dar cumplimiento al objeto de investigación, se realizó una revisión bibliográfica de la zona de estudio; se determinaron seis puntos de medición hídrica de los parámetros: OD, SST, DQO, CE, pH, CT, DBO y Q, teniendo en cuenta representatividad y accesibilidad. Obtenidos los resultados del laboratorio se hicieron los cálculos y el análisis para establecer el ICACOSU de 5 y 7 variables, y comparar los resultados de los parámetros con los objetivos de calidad hídrica establecidos para el río Fucha. Se deduce que la calidad del río Fucha para el ICACOSU de siete variables es muy malo para los puntos de monitoreo 5 y 6, por la disminución en la concentración de OD (0.35 y 0.17 mg/l O2, respectivamente) y el aumento de la concentración de DBO5 en el punto de monitoreo 6 (112 mg/l O2); sólo los puntos de monitoreo 2 y 3 cumplen con un valor superior al 50 % en el cumplimiento de los objetivos de calidad hídrica.

Résumé :

The presented paper deals with the evaluation of hydropower potential in a selected section of the Torysa river in the eastern part of the Slovak Republic. This part of the country was chosen based on the existence of a significant risk of increasing energy poverty in local marginalized communities. Small hydropower plants in the form of mini and micro installations are an ecological and economical way to secure electricity and suppress indicators of energy poverty. The essential part of work focuses on the quantification of the gross (theoretical), technical, and economic hydropower potential of the Torysa river using elevation data obtained by GIS tools and hydrological data provided by The Slovak Hydrometeorological Institute. The next step identified concrete locations with a suitable head and volumetric flow rate. In the last part, the assessed section of the Torysa river was analyzed in terms of geographical collisions with NATURA 2000 areas, historical heritage elements in the country, and natural water bodies without hydropower potential (i.e., lakes, ponds, etc.). The resulting technical hydropower potential of selected part of Torysa river is 5425 kW and the economic potential is 1533 kW.

Résumé :

Abstract In several points of rivers Toksa, Neva and water objects related to them chemical analysis of water was done, optical density at 254 nm (OD254) and SUVA254 were determined. Tributaries of the Toksa polluted by domestic wastewaters showed values increased several fold (compared to the Toksa waters) for: colour, OD254, TOC, electric conductivity (EC), concentrations of ammonium (up to 10 maximal allowable levels for surface waters) and chlorides. SUVA254 (in L/(mgTOC·m)) belonged to the following ranges: 1.8-3.0 in the Toksa and its source; 2.3-6.3 in its polluted tributaries; 2.7-3.5 in the Neva and its source; 2.1-2.6 in the tap water of St. Petersburg. For express control of the pollution in the Toksa and other rivers with similar properties measurement of EC and OD254 could be recommended. Control of organic matter content based solely on OD254 cannot be precise due to variations of SUVA254.

Résumé :

Bicycles and motorcycles are characterized by large rider-to-vehicle mass ratios, thus making estimation of the rider’s inertia especially relevant. The total inertia can be derived from the body segment inertial properties (BSIP) which, in turn, can be obtained from the prediction/regression formulas available in the literature. Therefore, a parametric multibody three-dimensional rider model is devised, where the four most-used BSIP formulas (herein named Dempster, Reynolds-NASA, Zatsiorsky–DeLeva, and McConville–Young–Dumas, after their authors) are implemented. After an experimental comparison, the effects of the main posture parameters (i.e., torso inclination, knee distance, elbow distance, and rider height) are analyzed in three riding conditions (sport, touring, and scooter). It is found that the elbow distance has a minor effect on the location of the center of mass and moments of inertia, while the effect of the knee distance is on the same order magnitude as changing the BSIP data set. Torso inclination and rider height are the most relevant parameters. Tables with the coefficients necessary to populate the three-dimensional rider model with the four data sets considered are given. Typical inertial parameters of the whole rider are also given, as a reference for those not willing to implement the full multibody model.

Résumé :

The purpose of this work is to study the kinematics and injury of child pillion passenger from motorcycle-to-car crash tests. Two crash tests for rear and front child pillions were set up. The kinematics of dummies were analysed from accelerometer data and high speed camera pictures. The kinematics and injury mechanisms of the child passenger from both tests are significantly different. For the rear child pillion test, the rider impacted the car before the child passenger. Both rider and child were ejected upward. The child’s head motion was curvilinear towards the car structure. This results in severe head injury due to high HIC. The child sitting at front translated in the longitudinal axis of the motorcycle and impacted the car before the rider. The child’s torso strongly hit to the handlebar first then head hit the car. This results in low value of HIC. The child’s upper-body including neck were compressed between the car and the rider’s torso leading to high risk of severe thorax and neck injuries. The results reveal that the child sitting behind the rider has higher risk of severe head injury while the child sitting before the rider has higher risk of thorax and neck injuries.

In 2018-2019, the zooplankton was studied in the Don River from the source to the mouth including the Tsimlyansk Reservoir, Volga-Don shipping canal, and the upper part of Taganrog Bay of the Sea of Azov. Habitats of two Ponto-Caspian species of copepods ( Heterocope caspia and Eurytemora caspica ) and of three alien species, Mediterranean copepod Calanipeda aquaedulcis , a representative of the neritic zone Acartia ( Acanthacartia ) tonsa and East Asian euryhaline Thermocyclops taihokuensis were found. For the first time, the findings of T. taihokuensis were recorded in the Don River upstream and downstream of the Tsimlyansk Reservoir and in water bodies of the Volga-Don shipping canal. It is shown that the Ponto-Caspian Eurytemora caspica inhabits the Don River basin and Taganrog Bay of the Sea of Azov. The European copepod E. affinis which was previously recorded in the region was not found in the studied areas of the basin. The occurrence (>80% of samples) of the Ponto-Caspian species and Calanipeda aquaedulcis was the highest. A recent invader Thermocyclops taihokuensis reached the maximum abundance (>100 000 ind./m). By an example of the Tsimlyansk Reservoir, it is found that the way of the spread of the Ponto-Caspian and alien species in the Don River basin may be large-scale activities on the introduction of planktonic and benthic invertebrates conducted in the 1950-1970s in order to improve the food supply of valuable fish species. The history of dispersal of the studied copepod species and their population characteristics are discussed.

Résumé :

Kadapa is a town in the Rayalaseema area of southern side of state Andhra Pradesh, India, commonly known as the key-part of Rayalaseema. It serves as the important business centre in YSR district. The city had a population of 344,078 according to the 2011 Indian census. It’s approximately 8.0 kilometres (5.0 miles) south of the Penna River. Due to unpredictable and uncertain rains, the Kadapa is a drought prone area; in fact, more than 75% of the mandal is a drought area. As a result, the government declared droughtprone areas not just in mandals, but also in urban areas with more than ten panchayats facing drinking water shortages. As a result of the aforementioned circumstances, the government of Andhra Pradesh created the Galeru Nagari Sujala Sravanthi Project [GNSS] project for water supply in drought prone area. A field experiment was planned and conducted during the Rabi season of 2019-20 at agricultural research centre, school of agricultural sciences, SGRRU, Dehradun Uttarakhand, to investigate the “Effect of macronutrients on the growth and yield of Rapeseed/toria”. The experiment was laid out in randomized block design with three replication and 8 treatments. Treatments constituted viz. Sulphur (Basal application). Sulphur (Foliar application), Sulphur (Basal+Foliar application), NPK (Basal) + Ca Mg:S (Basal), NPK(Basal) + Ca Mg S(Foliar), NPK(Foliar)+ Ca Mg S (Foliar) .70 kg/ha NPK with the recommended dose of 40:30:30,18 kg/ha Ca, 6kg/ha Mg. 40kg/ha S used in different doses in all treatments. The crop variety PR 2006 (Pant Rai 19) was shown on November 15, 2019 and harvested on March 25, 2020. Observation on various growth parameters, field attributes and yield were recorded. The seed and stover samples at harvest were collected; finally the economics of different treatments were worked out. Fertilizer management treatments significantly influenced various growth parameters, yield attributes and yield of mustard. Plant height, number of branches per plant, number of leaves per plant, number of siliqua/plant, number of seeds/siliquae yield recorded had significantly higher values under treatment T6 (NPK (Foliar) + Ca Mg S (Foliar) followed by T5-NPK (Basal)+ Ca:Mg:S (Foliar application) and T4- NPK (Basal)+Ca Mg:S ( Basal) NPK (Foliar)+ Ca: Mg S(Foliar) T6 though recorded maximum seed yield (1875 kg/ha) but was statistical at par with NPK(Basal)+Ca:Mg S (Foliar) (1748kg/ha) and was significantly superior over remaining treatments. The treatment shows significantly high yield and plant growth in which all macronutrients are used as foliar application.

Résumé :

Peritrich ciliates are commonly found as epibionts, colonizing living organisms, or attached to non-living substrates in freshwater, estuarine and marine environments. Several species of peritrich epibionts are obligate, which means that they are able to only colonize other organisms, while others are facultative attaching to living or non-living substrates. The peritrich Zoothamnium intermedium is commonly found as epibiont on the copepod species Acartia tonsa and Eurytemora affinis in Chesapeake Bay, USA. Previous studies demonstrated that Z. intermedium is not able to attach to non-living substrates in the laboratory; with free-swimming stages (telotrochs) dying when living substrates are not available for colonization. The present study investigated the ability of Z. intermdium to colonize artificial substrates in the field. Observations were carried out while the peritrich ciliate was colonizing copepods in Rhode River, a tributary of Chesapeake Bay. Results demonstrated that four species of Zoothamnium were recovered from artificial substrates, but none of them was Z. intermedium. At the same time, Z. intermedium was colonizing adults and copepodites of E. affinis and A. tonsa during the whole study period. These results, in addition to laboratory observations, suggest that Z. intermedium is an obligate epibiont.

Résumé :

The taxonomic composition and dynamics of the abundance of holoplankton and meroplankton were studied in the estuary of the seaport Temryuk and in Temryuk Bay (background) in autumn 2018. The impact of the trading port and the Kuban River on the state of holoplankton and meroplankton was assessed. The abundance of holo- and meroplankton in the more desalinated and polluted estuary of the port, which borders the Kuban River, was 1.5–3 times lower than in the Temryuk Bay. In the composition of the copepods Oithona davisae and Acartia tonsa, up to half of non-viable individuals were found in the port estuary. In early autumn, the holoplankton was dominated by Oithona davisa and freshwater cyclopoid copepods; in Temryuk Bay, O. davisae prevailed; in meroplankton, larvae of mollusks wee ubiquitous. At the end of autumn, freshwater cyclopoid copepods and larvae of cirripede barnacles Amphibalanus improvisus were abundant in the port estuary; in the bay, along with O. davisae, brackish-water copepods Еurytemora affinnis, larvae of cirripede barnacles A.improvisus were abundant. The basis of the pool of merorplankton was species tolerant to water eutrophication and sulfide contamination of bottom sediments (A. improvisus, Bittium reticulatum and Bivalvia).

Résumé :

As the schooner Toroa carried its only passenger, Conrad Martens, up the Brisbane River on 7 November 1851, he would have seen many places subsequently depicted in his art works, including the then recently erected large residences Newstead and Bulimba (both extant). Approaching the main settlement further upstream, the ship passed New Farm and North Brisbane on the right, and Bulimba and Kangaroo Point on the left, before finally berthing at South Brisbane. The most prominent landmark in Brisbane was a derelict windmill (extant) on a hill at North Brisbane overlooking the settlement. Martens' illustrations show us, through the artist's eye, Brisbane's appearance in late 1851. This, combined with other documentary evidence, enables us to paint our own mental picture of Brisbane at the time.

Résumé :

Lowering of the upper body to optimize cycling time trial (TT) performance is a balance between the aerodynamic advantage related to a lower frontal area and prospective detrimental physiological effects associated with a reduction of the hip-torso angle. To explore this in elite athletes and across positions relevant for competitive cyclists, we analysed racing positions for world championships [WC] top-10 finishers and 10 national elite TT-cyclists. Subsequently, laboratory studies were completed to evaluate effects on exercise economy, muscle oxygenation and perceived exertion for the national TT-group for their habitual position and compared to standard (4-12-20˚) torso angles. Hence, covering the racing position observed for top-10 WC finishers (positioned from 4-12˚) and the national elite (range 8-18˚). Oxygen calorimetry and near-infrared spectroscopy revealed that there was no difference in overall energy expenditure, delta exercise efficiency or muscle oxygenation across the investigated range of positions. However, rating of perceived exertion was significantly elevated for the lowest position (4˚ torso angle) compared to the rider’s habitual position. This lets us conclude that elite TT-cyclists can acutely adopt to a very low upper body position without compromising exercise economy or muscle oxygenation and some WC-level TT riders have adopted this low (4˚) racing position. However, the elevated perception of exertion with an acute reduction of the torso-hip angle indicates that it presumably requires specific training in the position or factors not related to exercise economy and muscle oxygenation determine if a rider in practice can perform in the very low position.

Résumé :

Telah dilakukan kaji eksperimental turbin air Darrieus tipe-H menggunakan blade hydrofoil standar NACA 2415 untuk mengetahui nilai torsi statik dan dinamik yang dihasilkan turbin air Darrieus tipe-H 3 blade dan 6 blade, pengujian menggunakan water tunnel dimensi 6m x 0.6m x 1m. Variasi tiga blade dan enam blade, dengan diameter turbin 0.44 m x 0.15 m pada turbin luar dan 0.18 x 0.14 m pada turbin bagian dalam, panjang chord 0.10 m dengan variasi sudut serang 0º sampai dengan 360º, variasi kecepatan air pertama 0.3 m/s, variasi kecepatan aliran air kedua 0.65 m/s. Kecepatan air 0.3 m/s enam blade, torsi statik 0.3 Nm, torsi dinamik nya 0.384 Nm, kecepatan air 0,65 m/s torsi dinamik 0.432 Nm dan torsi statik nya 0.384 Nm, pengujian turbin Darrieus tiga blade kecepatan air 0,3 m/s nilai torsi dinamik 0.336 Nm dan dengan kecepatan yang sama torsi statik nya 0.264 Nm. Pada kecepatan air 0.65 m/s nilai torsi dinamik sebesar 0.384 Nm, dan nilai torsi statik 0.336 Nm. Dari data hasil pengukuran tersebut dapat disimpulkan bahwa variasi turbin enam blade memiliki nilai torsi statik dan torsi dinamik yang lebih tinggi dari pada turbin tiga blade, jumlah blade sangat berpengaruh terhadap daya serap energi kinetik air untuk di konversikan menjadi torsi statik maupun torsi dinamik.Kata kunci : Turbin Hydrokinetic, Darrieus, Torsi Statik,Torsi DinamikAn experimental study of the H-type Darrieus water turbine was carried out using a standard NACA 2415 hydrofoil blade to determine the value of static and dynamic torque generated by the 3-blade and 6-blade Darrieus H-type water turbine, testing using a water tunnel dimensions of 6m x 0.6m x 1m. Variation of three blades and six blades, with a turbine diameter of 0.44 mx 0.15 m on the outer turbine and 0.18 x 0.14 m on the inner turbine, chord length 0.10 m with variations in angle of attack 0º to 360º, variation of first water velocity 0.3 m / s second water flow velocity 0.65 m / s. Water velocity 0.3 m / s six blades, static torque 0.3 Nm, dynamic torque 0.384 Nm, water velocity 0.65 m / s dynamic torque 0.432 Nm and static torque 0.384 Nm, Darrieus three blade turbine test water speed 0.3 m / s dynamic torque value of 0.336 Nm and with the same speed its static torque is 0.264 Nm. At 0.65 m / s water velocity, the dynamic torque value is 0.384 Nm, and the static torque value is 0.336 Nm. From the measurement data, it can be concluded that the six-blade turbine variation has a higher value of static torque and dynamic torque than the three-blade turbine, the number of blades greatly influences the absorption of water kinetic energy to be converted into static torque and dynamic torque.

Résumé :

IN KING SOLOMON'S MINES(1885), H. Rider Haggard describes the journey of three robust English men who successfully penetrate a sexualized landscape in southern Africa, depicted as both the body of the long-dead Queen of Sheba and that of her contemporary, King Solomon. The three English adventurers, led by the narrator Allan Quatermain, climb “Sheba's breasts” (26; ch. 2), traverse her torso, and arrive finally at the location where diamonds are stored inside her cavernous body, in the space Haggard calls “King Solomon's treasure chamber” (27; ch. 2). Narrative desire and the mystery of the Jewish patriarch's ancient empire propel these men through a series of male bonding adventures that lead to their arrival and conquest of the famed mines, where they pocket diamonds “as large as pigeon-eggs” (225; ch. 17) and plot their escape from what they fear may be a sealed cave.

Résumé :

Os processos decisórios de gestão de bacias hidrográficas dependem de informações qualificadas, pautadas na realidade e diversidade dos sistemas hídricos. No Brasil, o diagnóstico ambiental de sistemas fluviais baseia-se principalmente em análises realizadas através de estações de monitoramento. Estas avaliações, no entanto, apresentam alto custo e consideram apenas parâmetros físico-químicos e bacteriológicos da água, desconsiderando aspectos morfológicos, sedimentológicos e ecológicos. Frente a esta limitação, torna-se desejável a utilização de ferramentas práticas, que permitam uma análise ambiental pouco onerosa e integrada de cursos d’água. Diante deste contexto, o presente estudo teve como objetivo conceber um Protocolo de Avaliação Rápida (PAR) para aplicação em sistemas fluviais do Parque Nacional da Serra do Gandarela (MG) e discutir suas potencialidades como instrumento de suporte ao monitoramento e gestão de recursos hídricos. Os resultados demonstraram que o PAR pode ser considerado como uma ferramenta viável, já que a partir de sua aplicação foi possível detectar, de forma rápida e prática, alterações gradativas na qualidade ambiental do curso d’água avaliado.Palavras–chave: Protocolos de Avaliação Rápida, Gestão de sistemas fluviais, Avaliação ambiental, Qualidade ambiental.Abstract Decision-making processes for river basin management depend on qualified information, based on the reality and diversity of water systems. In Brazil, the environmental diagnosis of river systems is based mainly on the analysis carried out through monitoring stations. These assessments, however, present high costs and consider only physical-chemic and bacteriological water parameters, disregarding morphological, sedimentological and ecological aspects. Faced with this limitation, it is desirable to use practical tools that allow a cheap and integrated evaluation of river systems. In this context, the present study aimed to design a Rapid Assessment Protocol for application in river systems of the Serra do Gandarela National Park (MG) and to discuss its potential as an instrument to support the monitoring and management of water resources. The results showed that the protocol could be considered a viable tool, since from its application it was possible to detect, quickly and practically, gradual changes in the environmental quality of the evaluated watercourse.Keywords: Rapid Assessment Protocols, Fluvial systems management; Environmental Assessment; Environmental quality.

Résumé :

A total of 61 zooplankton taxa were found in the southwestern Caspian Sea between 1996 and 2010. Thirteen of them were meroplankton taxa and forty-eight were holoplankton taxa. The occurrence of 14 freshwater taxa indicated the influence of the Anzali wetland and river inflows. The decrease in zooplankton taxa was detected since 1996-1997 and continued till 2010.Pleopis polyphemoides, the only one out of the nine recorded Cladocera species in 1996-1997, was found after 2001. Similarly, of the five Copepoda species recorded in 1996-1997, only one,Acartia tonsa, was found abundant during the 2001–2010 sampling period. It was striking that many species which were abundant in the Caspian Sea in 1996-1997 were not found after 2000. Many reasons could have contributed to the changes in the zooplankton composition of the southern Caspian Sea, notably the serious environmental degradation since the early 1990s. It is also possible that invasive species might play a role in wiping out some sensitive endemic species.

Résumé :

Riverbed farming is a sustainable, productivity-enhancing technology suitable for dissemination in other appropriate areas. It has been shown to be economically viable, environmentally sustainable, socially acceptable and technologically appropriate for landless and land-poor farmers in the Terai region. The study was conducted on five villages from three riverbed systems with 20 respondents from each village thereby totaling number of 100 respondents. The data were collected on information about riverbed cultivation, marketing of riverbed products, prospects of riverbed cultivation and constraints of riverbed cultivation. The results shows that 100% respondents give first rank to proper utilization of riverbed land for adopting riverbed cultivation and 100% accept that they have used income from riverbed cultivation to setup other occupations. It was also shown that most of the farmers sell their produce through middlemen from the farm that was 75% in Singimari river bed system followed by 65% in Torsha and 60% in Shiltorsha respectively and transportation was the most important constraint having mean value 2.83

Résumé :

In Brazil, about 49% of the population does not have access to the sewage collection network, with the consequent direct discharge of their sewage network into water bodies. Due to this scenario, it is essential to investigate the quality of the water consumed by thousands of people along the Negro and Resende Rivers. The present study analysis the waters of the Negro and Resende rivers, located in Dois Rios River Basin, in the municipality of Duas Barras, Rio de Janeiro State (RJ, SE Brazil), based on the Water Quality Index proposed by the National Sanitation Foundation (United States). The population of the district located in the municipality of Duas Barras dumps the domestic sewage directly into the hydrographic network. The analyzed parameters were: turbidity, total solid residue, total phosphorus, total nitrogen, biochemical oxygen demand (BOD), hydrogenation potential, temperature, dissolved oxygen and thermotolerant coliforms. The values obtained from the calculation of the Water Quality Index (WQI) showed a variation from 40 to 68, meaning that the quality of water vary between bad and acceptable in the study area. The samples collected in the urban area contained values for thermotolerant coliforms in disagreement with the maximum value permissible for classes 2 and 3 of fresh water by CONAMA (Conselho Nacional do Meio Ambiente; a Brazilian Council for the Environment) Resolution 357/2005. The results of the analyzes confirmed the contamination of the two rivers by the discharge of domestic effluents, showing that actions are necessary to eliminate or minimize the discharge of sewage in the surveyed water bodies, since it may cause public health risks. ResumoNo Brasil, cerca de 49% da população não possui acesso à rede de coleta de esgoto, com o consequente despejo direto da sua rede de esgotos em corpos hídricos. Diante deste cenário, torna-se indispensável investigar a qualidade da água consumida por milhares de pessoas ao longo dos rios Negro e Resende. A presente pesquisa analisou qualitativamente as águas dos rios Negro e Resende, localizados na Bacia Hidrográfica do Rio Dois Rios, no município de Duas Barras/RJ, a partir do índice de qualidade das águas proposto pela National Sanitation Foundation. A população do distrito sede do município de Duas Barras despeja o esgoto doméstico diretamente na referida rede hidrográfica. Os parâmetros analisados foram: turbidez, resíduo sólido total, fósforo total, nitrogênio total, demanda bioquímica de oxigênio, potencial hidrogêniônico, temperatura, oxigênio dissolvido e coliformes termotolerantes. Os valores obtidos no cálculo do índice de qualidade das águas (IQA) mostraram uma variação de 40 a 68, significando uma qualidade da água entre ruim e razoável. As amostras coletadas na área urbana apresentaram valores para coliformes termotolerantes em desacordo com o valor máximo permitido para classes 2 e 3 de água doce, regulamentados pela Resolução CONAMA 357/2005. O resultado das análises confirmou a contaminação dos dois rios pelo lançamento de efluentes domésticos, os quais poderão originar riscos de saúde pública. Os resultado evidenciam a necessidade de se desenvolverem ações para eliminar ou minimizar os despejos de esgotos nos referidos corpos hídricos.

Résumé :

AbstractThe formation of short-lived backswamps along the Carmel coast of Israel coincides with the rapid global sea-level rise during the late Pleistocene–early Holocene transition. The current study shows that the wetland phenomena originated around 10,000 yr ago and dried up shortly before the local Pre-Pottery Neolithic humans settled on the wetland dark clay sediments 9430 cal yr BP. Palaeontological and stable-isotope data were used in this study to elucidate previously published sedimentological reconstruction obtained from a core drilled into the western trough of the Carmel coastal plain. The water body contained typical brackish calcareous fauna, with variable numerical abundance and low species richness of ostracods and foraminifera. The δ18O and δ13C of the ostracod Cyprideis torosa show close similarity to the present Pleistocene coastal aquifer isotopic values. This study therefore concludes that the wetlands were shallow-water bodies fed by groundwater, with no evidence of sea-water mixing. It seems that they developed as the result of high groundwater levels, transportation of sediments landward, and deposition of sand bars at the paleo-river mouths. It is still not fully understood why these wetlands deteriorated abruptly and disappeared within less than 1000 yr.

Résumé :

Application of the Frier Distributed Model for Estimating the Impact of Land use Changes on the Water Balance in Selected Basins in SlovakiaIn this study, the FRIER rainfall-runoff model with distributed parameters was developed to assess changes in runoff and water balance due to changes in land use and climate. The water balance was calculated at 3 levels: on the surface and in unsaturated and saturated zones. Six basins from the central and eastern parts of Slovakia were selected on the basis of their similar size, but different topography, land use, soil texture and climate: the upper Hornád, the upper Hron, the Poprad, the Rimava, the Slaná and the Torysa River basins. Model parameters were estimated using data from the period from June 1998 to May 2000 in daily time steps. The differences and similarities of the hydrologic processes in individual basins were investigated during the calibration period. Several scenarios of changes in land use and two simple scenarios of changes in climate were developed to estimate the impact of these changes on water balance and runoff. The changes in the hydrological regime were compared and discussed.

Résumé :

Na sociedade de mobilidade crescente, que vem substituindo a sociedade à dominante sedentária, o contato com estranhos/estrangeiros/desconhecidos aumenta velozmente, alterando instituições basilares da sociedade como casa, vizinhança, família, trabalho. A garantia de ser bem recebido em todos os lugares para onde vamos torna-se uma necessidade. A urbanidade, o tratamento polido, mas impessoal não é mais suficiente. Crescem as reivindicações por uma hospitalidade mais carregada de calor humano. Mesmo no comércio, termos como customização, fidelização são marcas da aspiração de pessoalidade no encontro. A discussão desses temas é o contexto para o propósito deste artigo de, com base nas reflexões de Jacques Derrida, Marcel Mauss, Julian Pitt-Rivers e Anne Gotman, desvelar as quatro leis básicas da hospitalidade: a incondicionalidade, a reciprocidade, a assimetria e a compensação. Adicionalmente, pretende levantar outras questões que surgem à margem da atual discussão, em especial o caso do turismo.

Résumé :

O tipo de uso e ocupação das terras das bacias hidrográficas sem fiscalização ou planejamento adequado, torna-se um dos maiores responsáveis pela degradação de corpos hídricos, por isso surge a necessidade de avaliação da qualidade de suas águas. A qualidade das águas da bacia hidrográfica do ribeirão Paraíso, localizado no município de Jataí/GO, foi avaliada a partir do Índice de qualidade das águas (IQA), adaptado pelo Centro Tecnológico de Saneamento Básico do estado de São Paulo (CETESB) para condições tropicais. A pesquisa constituiu em aferir o índice de qualidade das águas em onze pontos de amostragem, em quatro períodos distintos. Os resultados encontrados foram comparados com a Resolução CONAMA n° 357/2005, e aplicado o índice de qualidade das águas (IQA), que classifica o corpo hídrico em 5 faixas de valores (de zero a 100). De acordo com os dados avaliados, a qualidade das águas do ribeirão Paraíso pode ser considerada boa, podendo ser destinadas ao abastecimento público, desde que se tenha tratamento adequado. Ao analisar separadamente cada parâmetro, os valores encontrados em algumas das análises de coliformes termotolerantes, pH, fósforo total e DBO estavam em desconformidade com a classe 1 da Resolução vigente, resultando em contaminação das águas. Com isso, conclui-se que são necessárias ações que possibilitem melhor manejo e uso na ocupação da terra e águas desta bacia, viabilizando a integridade das características do ribeirão, como também a prevenção de maiores alterações e degradação diante do aumento das atividades antrópicas encontradas na bacia hidrográfica em questão. A B S T R A C T The kind of land use and occupation in the river basins without supervision or proper planning has become one of the greatest responsible by hydrous bodies degradation, therefore there’s a need to evaluate the quality of the their water. The quality of the water of Ribeirão Paraíso river basin, located in the municipality of Jataí/GO, was evaluated from the Water Quality Index (WQI), adapted by the Technological Center of Basic Sanitation in the state of São Paulo (CETESB) for tropical conditions. The research aimed measuring the water quality index in eleven sample points, in four different periods. The obtained results were compared to CONAMA’s Resolution number 357/2005, and applying the water quality index (WQI), which classifies the hydrous body in five value bands (from zero do 100). According to the evaluated data, the quality of the water in Ribeirão Paraíso can be considered as good, with the possibility of being used for public supply, as long as it has proper treatment. Analyzing separately each parameter, the values found in some analyses of thermotolerant coliforms, pH, total phosphor and DBO were according to the class one in the current Resolution, resulting in the contamination of the water. Thus, it’s possible to conclude that actions which make it possible to a better land management and occupation and water in this river basin are necessary, enabling the integrity of the stream’s characteristics, as well as the prevention for major changes and degradation due to the increase of anthropic activities found in the studied river basin. Keywords: River Basin, Water Quality Index, use and occupation.
