The present study focused on the quality of rainwater at various land use locations and its variations on interaction with various domestic rainwater harvesting systems.Sampling sites were selected based upon the land use pattern of the locations and were classified as rural, urban, industrial and sub urban. Rainwater samples were collected from the south west monsoon of May 2007 to north east monsoon of October 2008, from four sampling sites namely Kothamangalam, Emakulam, Eloor and Kalamassery, in Ernakulam district of the State of Kerala, which characterized typical rural, urban, industrial and suburban locations respectively. Rain water samples at various stages of harvesting were also collected. The samples were analyzed according to standard procedures and their physico-chemical and microbiological parameters were determined. The variations of the chemical composition of the rainwater collected were studied using statistical methods. It was observed that 17.5%, 30%, 45.8% and 12.1% of rainwater samples collected at rural, urban, industrial and suburban locations respectively had pH less than 5.6, which is considered as the pH of cloud water at equilibrium with atmospheric CO,.Nearly 46% of the rainwater samples were in acidic range in the industrial location while it was only 17% in the rural location. Multivariate statistical analysls was done using Principal Component Analysis, and the sources that inf1uence the composition of rainwater at each locations were identified .which clearly indicated that the quality of rain water is site specific and represents the atmospheric characteristics of the free fall The quality of harvested rainwater showed significant variations at different stages of harvesting due to deposition of dust from the roof catchment surface, leaching of cement constituents etc. Except the micro biological quality, the harvested rainwater satisfied the Indian Standard guide lines for drinking water. Studies conducted on the leaching of cement constituents in water concluded that tanks made with ordinary portland cement and portland pozzolana cement could be safely used for storage of rain water.

Schiff base complexes of transition metal ions have played a significant role in coordination chemistry.In the present study we have synthesized some new Mn(II),Co(II) and Cu(II) complexes of Schiff bases derived from 1,8-diaminonaphthalene.Even though we could not isolate theses Schiff bases (as they readily cyclise to form the perimidine compounds),we were able to characterize unequivacally the complexes synthesized from these compounds as complexes of Schiff Bases. We Synthesized three perimidine derivatives ,2-(quinoxalin-2-yl)-2,3-dihydro-1H-perimidine,2-(2,3-dihydro-1H-perimidin-2-yl)-6-methoxyphenol and 4-(2,3-dihyro-1H-perimidin-2-yl)-2-methoxyphenol by the condensation of 1,8-diaminonaphthalene with quinoxaline-2-carboxaldehyde,2- hydroxy-3-methoxybenzaldehyde or 4-hydroxy-3-methoxybenzaldehyde respectively.Theses compounds were used as precursor ligands for the preparation of Schiff base complexes.The complexes were characterized by using elemental analysis ,conductance and magnetic susceptibility measuremets ,infrared and UV-Visible spectroscopy ,thermogravimetric analysis and EPR spectroscopy .We also encapsulated the complexes in zeolite Y matrix and these encapsulated complexes were also characterized. We have also tried theses complexes as catalysts in the oxidation of cyclohexanol and decomposition of hydrogen peroxide.

Methylparathion (MP) is an organophosphorus insecticide used world wide in agriculture due to its high activity against a broad spectrum of insect pests. The aim of the study is to understand the effect of methylparathion on the lipid peroxidation, detoxifying and antioxidant enzymes namely catalase (CAT), glutathione peroxidase (GPx), superoxide dismutase (SOD), glutathione Stransferase (GST), total reduced glutathione (GSH), lipid peroxidation (LPO), acetylcholinesterase (AChE) and disease diagnostic marker enzymes in liver, sarcoplasmic (SP) and myofirbirllar (MF) proteins in muscles, lipids and histopathlogical changes in various organs of Labeo rohita of size 75 i 6g at lethal and sublethal level of exposure. The probit analysis showed that the lethal concentration (LC 50%) for 24, 48, 72 and 96h were 15.5mg/L, 12.3mg/L, 11.4mg/L and 10.2mg/L respectively which is much higher compared to the LC50 for juvenile fish. The LPO level and GST activity increased five folds and two folds respectively on exposure to methylparathion at 10.2 mg/L and the level of the enzymes increased, on sub lethal exposure beyond 0.25mg/L. AChE activity was inhibited by 74% at a concentration of 1.8mg/L and 90% at 5.4mg/L. The disease diagnostic marker enzymes AST, ALT, ALP and LDH increased by about 2, 3 ,3 and 2 folds respectively at pesticide concentration of 10.2mg/L when compared to control. On sub lethal exposure, however the enzymes did not show any significant changes up to 0.5mg/L. At a concentration of 10.2 mg/L, there was a three fold increase in myofibrillar proteins while the increase in sarcoplasmic protein was above 1.5 fold. On sub lethal exposure, significant alteration was noticed up to 30 days up to 1mg/L of methylparathion concentration. Further exposure up to 45 days increased sarcoplasmic proteins (upto 0.5mg/L). ln the case of myofibrillar proteins, noticeable changes were observed at 1mg/L concentration right from 15th day. The cholesterol content in brain tissues increased by about 27% at methylparathion concentration of 5.4 mglL. However at 0.25mg/L sub lethal concentration, no significant alteration was observed in enzyme activity, muscle proteins, lipids and histopathology of the tissues. The results suggest that methylparathion has the potential to induce oxidative stress in fish, and that liver, muscle and brains are more sensitive organs of Labeo rohita, with poor antioxidant potentials at higher concentrations of the pesticide. The various parameters studied in this investigation can also be used as biomarkers of methylparathion exposure.

When we consider Kerala and Karnataka States according to their levels of decentralisation. Kerala is at the beginning of the scale of decentralisation whereas Kamataka has moved far ahead along this scale. Therefore I in order to conduct a comparative study of the SUbject under analysis t Kamataka has been selected owing to the fact that it is in an advanced stage in the experience of district planning compared to Kerala , Karnataka could successfully implement district planning and it is me of the pioneering states in this regard. But Kerala has not gained much experience in the field of decentralised district planning till now. Furthermore Kerala and Kamataka states are selected for the present study due to operational reasons I besides the author I s familiarity with the socia-economic conditions of these states. Thus. an analysis of the district planning experience of Kamataka will provide constructive and valuable information. which will be of great importance to Kerala State, which is now aspiring to introduce ful.I-f'Iedge district planning by constituting elected District Coancils in every district of Kerala. Moreover. the findings and policy implications of the present study will be of immense help to planners, politicians. administrators, academicians and people at large.

Urinary stones resected from urinary bladders of patients hailing from Kollam district of Kerala State, India were analyzed by SEM, XRD and by thermal analysis techniques. The analytical results indicate that, stones have different composition, i.e., calcium phosphate, calcium phosphate hydroxide and sodium calcium carbonate. Infrared spectral studies also reveal the presence of phosphates or carbonates in these samples. Further, IR spectral investigations have revealed that amorphous carbonated species are occupied in PO4 sites in calcium phosphate type stone and OH sites in calcium phosphate hydroxide sample. Thermal studies of these samples also reveal that, carbon dioxide is released from carbonated samples upon heating which is related to amount of carbon content and bond strength. Crystals with defects and irregular morphology are grown inside the urinary bladder due to variation in crystal growth conditions

Die Dissertation befasst sich mit der Geschichte des Arbeitserziehungslagers (AEL) Breitenau, das 1940 von der Gestapostelle Kassel auf dem Gelände der Landesarbeitsanstalt Breitenau in Guxhagen gegründet wurde und bis zum Kriegsende bestand. Darüber hinaus wird auch der Frage nachgegangen, wie nach der NS-Zeit mit der Geschichte des Lagers, den Opfern und den Tätern umgegangen wurde. Die Dissertation ist in drei Teile gegliedert. Der erste Teil gibt einen Überblick über die Geschichte der Geheimen Staatspolizeistelle Kassel, der das Lager unterstand und die als zentrale Verfolgungsbehörde für den Regierungsbezirk Kassel zuständig war. Dabei wird vor allem aufgezeigt, wie die Gestapostelle Kassel entstanden ist, wie sie aufgebaut war und wer die Leiter und Mitarbeiter während des Zweiten Weltkrieges waren, die die Verfolgungsmaßnahmen organisierten und durchführten. Der zweite Teil der Dissertation befasst sich mit der eigentlichen Lagergeschichte. Breitenau war eines der ersten Arbeitserziehungslager überhaupt. Die Hauptfunktion bestand darin, ausländische Zwangsarbeiter und Zwangsarbeiterinnen, die sich dem Arbeitseinsatz widersetzt hatten, durch harte Bestrafung gefügig zu machen. Gleichzeitig wurden in das AEL aber auch deutsche und ausländische Gefangene eingewiesen, die aus politischen, rassischen, religiösen oder weltanschaulichen Gründen verhaftet worden waren. Das Lager unterstand zwar der Geheimen Staatspolizei Kassel, wurde aber von den Bediensteten der Landesarbeitsanstalt mit geleitet. Im Verlaufe des Zweiten Weltkrieges waren im AEL Breitenau etwa 8.300 überwiegend ausländische Schutzhaftgefangene inhaftiert, unter denen sich ca. 1.900 Frauen und 6.400 Männer befanden. Bei den Einweisungen wirkten neben der Gestapostelle Kassel und der Gestapostelle Weimar zahlreiche Orts- und Kreispolizeibehörden mit, wodurch ein flächendeckender Verfolgungsapparat entstand. Insgesamt lassen sich über 1.000 letzte Wohnorte von Gefangenen ermitteln. Die Haft- und Lebensbedingungen im Lager waren vor allem für die ausländischen Gefangenen besonders unmenschlich, und es gab mehrere Todesfälle. Nachweislich wurden mehr als 750 Gefangene in Konzentrationslager deportiert, was für viele den Tod bedeutete. Außerdem wurden mindestens 18 polnische Gefangene von Angehörigen der Gestapo Kassel erhängt und noch unmittelbar vor Kriegsende ein Massenmord an 28 Gefangenen verübt. Erst mit dem Einmarsch der amerikanischen Soldaten am Ostersamstag 1945 wurde das Arbeitserziehungslager Breitenau endgültig aufgelöst. Im dritten Teil der Dissertation wird der Frage des Umgangs mit dem damaligen Geschehen nachgegangen. Dabei lässt sich feststellen, dass die Täter und Mittäter von deutschen Spruchkammern und Gerichten gar nicht oder kaum bestraft wurden. Gleichzeitig wurden ihnen verschiedene Möglichkeiten geboten, sich in die Gesellschaft zu integrieren. Die ehemaligen Gefangenen hatten dagegen keinen Anspruch auf Entschädigung, und auch eine gesellschaftliche Würdigung wurde ihnen versagt. Erst seit den 90er Jahren trat hier eine Veränderung ein, die allerdings für viele Verfolgte zu spät kam. Die Geschichte des Arbeitserziehungslagers Breitenau war viele Jahre verdrängt worden. Das Gelände diente bis 1949 als Landesarbeitsanstalt, dann als geschlossenes Erziehungsheim, und seit 1974 besteht dort eine psychiatrische Einrichtung. Erst 1979 wurde durch ein Forschungsprojekt an der Gesamthochschule Kassel die NS-Geschichte „wiederentdeckt“ und 1984 die Gedenkstätte Breitenau eingerichtet, die als Gedenk- und Bildungsort an das damalige Geschehen erinnert.

Organic agriculture in Uganda is developing at a fast pace and despite this trend Uganda is still unable to produce enough fresh and dry organic fruits mainly pineapple to meet the exporters demand. This current research investigated the strategies of farmers at production level by assessing the pros and cons of fruit growing, organic agriculture and fruit drying in order to understand the underlying causal factor for the low production of organic dry fruits in a major fruit producing district of Uganda. The study was carried out in two separate and distinctive areas; one which only produces and export fresh organic pineapple and the other which exports dried fruits (mainly pineapple and papaya). About 10% of the farmers in the two study areas were surveyed using questionnaires which were further followed by semi-structured interviews and participatory rural appraisals activities with various types of farmers in order to understand the different decisions and strategies of farmers. 82% and 74% of farmers in the two study areas grew fruits as it gave better economic returns and for 77% and 90% respectively in the two study areas, the reasons for growing fruit was the ease of selling compared to other crops. All the farmers were relying on coffee husk for growing organic pineapples. However, 50% of the farmers want to grow pineapples (either organic or conventional) but couldn't afford to buy coffee husk. Fruit drying was mainly a strategy to utilize cheap fruits during harvesting seasons for value addition. 71% and 42% of farmers in the two study areas wanted to dry fruits but it was beyond their economic capacity to buy the driers. Decision of the farmers whether to grow fruits or cereals, organic or conventional agriculture and selling the fruits as fresh or dry were dependent mainly on the economic, knowledge and resource availability of each type of practices. It is concluded that the main barrier for an increase in the production of organic dried fruits is at the processing level, and the limited capacity for investments in drying facilities.

Artisanal columbite-tantalite (coltan) mining has had negative effects on the rural economy in the great Lakes region of Africa through labor deficits, degradation and loss of farmland, food insecurity, high cost of living, and reduced traditional export crop production alongside secondary impacts that remotely affect the quality of air, water, soil, plants, animals, and human wellbeing. The situation is multifaceted and calls for a holistic approach for short and long-term mitigation of such negative effects. This study focuses on the effects of mine land restoration on soil microbiological quality in the Gatumba Mining District of western Rwanda. Some coltan mine wastelands were afforested with pine and eucalyptus trees while farmers directly cultivated others due to land scarcity. Farmyard manure (FYM) is the sole fertilizer applied on the wastelands although it is insufficient to achieve the desired crop yields. Despite this, several multi-purpose plants such as Tithonia diversifolia, Markhamia lutea, and Canavalia brasiliensis thrive in the area and could supplement FYM. The potential for these “new” amendments to improve soil microbial properties, particularly in the tantalite mine soils was investigated. The specific objectives of the study were to: (a) evaluate the effects of land use on soil microbial indices of the tantalite mine soils; (b) investigate the restorative effects of organic amendments on a Technosol; and (c) estimate the short-term N and P supply potential of the soil amendments in the soils. Fresh soils (0-20 cm) from an unmined native forest, two mine sites afforested with pine and eucalyptus forests (pine and eucalyptus Technosols), an arable land, and two cultivated Technosols (Kavumu and Kirengo Technosols) were analyzed for the physicochemical properties. Afterwards, a 28-day incubation (22oC) experiment was conducted followed by measurements of mineral N, soil microbial biomass C, N, P, and fungal ergosterol contents using standard methods. This was followed by a 12-week incubation study of the arable soil and the Kavumu Technosol amended with FYM, Canavalia and Tithonia biomass, and Markhamia leaf litter after which soil microbial properties were measured at 2, 8, and 12 weeks of incubation. Finally, two 4-week incubation experiments each were conducted in soils of the six sites to estimate (i) potential mineralizable N using a soil-sand mixture (1:1) amended with Canavalia and goat manure and (ii) P mineralization mixtures (1:1) of soil and anion exchange resins in bicarbonate form amended with Tithonia biomass and goat manure. In study one, afforestation increased soil organic carbon and total N contents in the pine and eucalyptus Technosols by 34-40% and 28-30%, respectively of that in the native forest soil. Consequently, the microbial biomass and activity followed a similar trend where the cultivated Technosols were inferior to the afforested ones. The microbial indices of the mine soils were constrained by soil acidity, dithionite-extractable Al, and low P availability. In study two, the amendments substantially increased C and N mineralization, microbial properties compared with non-amended soils. Canavalia biomass increased CO2 efflux by 340%, net N mineralization by 30-140%, and microbial biomass C and N by 240-600% and 240-380% (P < 0.01), respectively after four weeks of incubation compared with the non-amended soils. Tithonia biomass increased ergosterol content by roughly 240%. The Kavumu Technosol showed a high potential for quick restoration of its soil quality due to its major responses to the measured biological parameters. In study three, Canavalia biomass gave the highest mineralizable N (130 µg g-1 soil, P < 0.01) in the Kavumu Technosol and the lowest in the native forest soil (-20 µg g-1 soil). Conversely, the mineralizable N of goat manure was negative in all soils ranging from -2.5 µg N g-1 to -7.7 µg N g-1 soil except the native forest soil. However, the immobilization of goat manure N in the “cultivated soils” was 30-70% lower than in the “forest soils” signifying an imminent recovery of the amended soils from N immobilization. The mineralization of goat manure P was three-fold that of Tithonia, constituting 61-71% of total P applied. Phosphorus mineralization slightly decreased after four weeks of incubation due to sulfate competition as reflected in a negative correlation, which was steeper in the Tithonia treatment. In conclusion, each amendment used in this research played a unique role in C, N, and P mineralization and contributed substantially to microbial properties in the tantalite mine soils. Interestingly, the “N immobilizers” exhibited potentials for P release and soil organic carbon storage. Consequently, the combined use of the amendments in specific ratios, or co-composting prior to application is recommended to optimize nutrient release, microbial biomass dynamics and soil organic matter accrual. Transport of organic inputs seems more feasible for smallholder farmers who typically manage small field sizes. To reduce acidity in the soils, liming with wood ash was recommended to also improve P availability and enhance soil biological quality, even if it may only be possible on small areas. Further, afforestation with mixed-species of fast-growing eucalyptus and legume or indigenous tree species are suggested to restore tantalite mine wastelands. It is emphasized most of this research was conducted under controlled laboratory conditions, which exclude interaction with environmental variables. Also fine fractions of the amendments were used compared with the usual practice of applying a mixture of predominantly coarser fractions. Therefore, the biological dynamics reported in the studies here may not entirely reflect those of farmers’ field conditions.

Los procesos transnacionales han marcado un cambio en las relaciones entre los actores del sistema internacional, permitiendo el trabajo por diversas causas a través de las fronteras. Esto ha sido aprovechado por los movimientos sociales, para que su lucha no quede enmarcada simplemente en su país, sino que a partir de objetivos, problemáticas, valores y acciones similares se vea reflejado en diferentes Estados y se de una acción común y colectiva para generar un cambio. Este fenómeno ha sido tomado como referente el Movimiento Pro-choice para articularse transnacionalmente en Colombia para la promoción de los Derechos Sexuales y Reproductivos en el periodo de 2001 a 2011, alcanzando una serie de objetivos importantes que han permitido cambios legales al interior del país, generando también un cambio dentro de la sociedad colombiana. El estudio, análisis y comprensión de la articulación del movimiento prochoice a partir de una dinámica transnacional para la promoción de los derechos sexuales y reproductivos en Colombia, se perfila como un tema de importancia por su coyuntura actual en el mundo, puesto que ha estado latente en los últimos veinte años. Igualmente, la identificación de la acción de los MST como otros actores internacionales en la transformación de las sociedades tanto locales como internacionales, traducido como un fenómeno que se puede explicar dentro de las Relaciones Internacionales.

El artículo explora las experiencias francesas del modelo de policía de proximidad. Con base en la división policial francesa entre la gendarmería de corte militar y la policía nacional, institucional civil. El autor da cuenta de las experiencias de vieja data y el desarrollo que ha tenido la policía de proximidad en Francia. Aunque el modelo fue adoptado de manera reciente en ese país (desde finales de los años 90), la policía francesa ha tenido siempre una vocación de cercanía con los vecinos y los ciudadanos en general. Sin embargo, recientemente las experiencias de policía de proximidad han cedido ante las tareas y políticas de represión impuestas para combatir la delincuencia creciente. Sólo las policías municipales, enteramente dependientes de los alcaldes y tradicionalmente cuestionadas, han suplido tangencialmente este rol de policía cercana a la comunidad. El modelo de policía de proximidad en Francia no ha sido suficientemente evaluado y se encuentra en medio del debate sobre su eficacia real.-----This article examines the French experience with the so called ‘police de proximite’ or ‘proximity police’. Based on the French division of the police force into the gendarmerie, of military nature, and the national police, a civil institution, the autor describes in detail the experiences and developments of the longstanding ‘police de proximite’ in France. Even if the model was established as recently as the late 90’s, the French police force has tended right from its beginnings to be close to neighbours and citizens in general, an experience that has yielded lately to repressive tasks and policies to combat a raising crime rate. Only the local boroughs’police, entirely dependent on the city mayors and traditionally called into question, has marginally played this role of communityclase policing. In short, the proximity policing model has not been sufficiently assessed and its efficiency is now in the middle of intense debate.

El artículo analiza los determinantes de la presencia de hijos no deseados en Colombia. Se utiliza la información de la Encuesta Nacional de Demografía y Salud (ENDS, 2005), específicamente para las mujeres de 40 años o más. Dadas las características especiales de la variable que se analiza, se utilizan modelos de conteo para verificar si determinadas características socioeconómicas como la educación o el estrato económico explican la presencia de hijos no deseados. Se encuentra que la educación de la mujer y el área de residencia son determinantes significativos de los nacimientos no planeados. Además, la relación negativa entre el número de hijos no deseados y la educación de la mujer arroja implicaciones clave en materia de política social.

La presente investigación tiene como objetivo principal, explicar la influencia de la línea de intervención de Seguridad Humana del plan 75-cien, en la seguridad ciudadana de la UPZ Las Cruces, con el fin de demostrar que la política pública no influye de manera significativa en la seguridad ciudadana de la UPZ Las Cruces, ante la participación casi nula de la Policía Nacional en el proyecto. A pesar de que la intervención focaliza el territorio y prioriza las necesidades sociales, el vacío que existe en el trabajo conjunto entre la Policía y la Secretaria Distrital de Gobierno, implica que no se establezcan acciones policivas que acompañen las estrategias de desarrollo humano para evitar o disuadir el delito. Por lo tanto a partir de la utilización del método cualitativo, se recolectaran datos de grupos focales, informes de las fuentes primarias y un diagnóstico de la línea de intervención, que permitan un análisis descriptivo y explicativo del fenómeno.
