This study looks at the effect of the sea water is having on the Densu delta wetland. The objective of this work is to assess the hydro- chemical dynamics of the surface water from the Densu delta using hydro chemical parameters, stable isotopes- oxygen-18 and deuterium and also asses the quality of the surface water for purposes like irrigation using SAR, %Sodium and other modules. Samples of surface water were taken for physico-chemical analysis. The samples were analysed for physical and chemical parameters and the stable isotopes (18 O and D2O). The results from the stable isotopes have shown that the quality of the surface water is being affected by slight mixing with sea water. From the SAR calculation, 62% and 38% of the water was within the excellent and good category respectively and none were within the doubtful and unsuitable category respectively. Calculation of % sodium showed that about 5 out of 8 samples have high sodium percent (above 60%) and are not suitable for irrigation purposes as per classification of Eaton 1950. From the Richards diagram, approximately 12.5% fall within good category; 75% in the category of doubtful; 12.5% within unsuitable category. Approximately 50% of the samples were found to be good by RSC index; 37% fall within the doubtful category and 13% unsuitable. A high percentage was within permissible ranges for TDS. The results suggest that generally water samples are suitable for domestic and irrigation purposes under normal temperature and pH condition.

Fertilizer is defined as any substance which is organic or inorganic, natural or artificial, supplies one or more of the chemical elements required for plant growth. Carbon, oxygen and hydrogen are directly supplied by air and water and therefore not treated as nutrients by the fertilizer industry. One of the vital industries for the Indian economy is the Indian Fertilizer Industry as it manufactures a very critical raw material for agriculture which is the major occupation of the country. The fertilizers especially like the ammonia urea plants are energy demanding in their operation. The fertilizer industry is passing through a critical phase which promises to significantly alter the future of the industry. The country needs to ensure smooth and timely availability of fertilizer to all parts of the country. The marketing divisions of the fertilizer industry will continue to handle millions of tonnes of fertilizer material. Greater responsibilities will be thrust upon the marketing personnel as they are among the limited gateways to rural India. New opportunities are likely to unfold in the rural sector which will encourage fertilizer industry to add new activities for their marketing divisions. The present study investigates the different aspects of the process of marketing of fertilizers. Specifically, an attempt has been made to study the marketing practices of the fertilizers producers supplying fertilizer to the farmers in Haryana.

This paper takes an apriori look at media convergence through the eyes and recommends that apostoriorily these convergences must continue to avert the death of some media even in our modern challenges of not only mass communication as a whole but broadcasting in particular with a focus on Federal Radio Corporation of Nigeria (FRCN).

Metastasis to the pancreas, are uncommon and usually sign of extensive disease ; they remain asymptomatic or are associated with nonspecific complaints . it may be difficult to differentiate a pancreatic metastasis from a primary pancreatic tumor, being the clinical presentation and the radiological characteristics similar for both primary and secondary neoplasms. The cytomorphology in combination with the clinical history and immunohistochemical findings can indicate a definitive diagnosis and avoid additional time-consuming diagnostic procedures for appropriate clinical management ; We aim to expose an exceptional case of a patient with a medullary thyroid carcinoma metastatic to the pancreas

Abstract The recent past ongoing string of financial crisis across the globe resulted in rising inflation, slowdown in industrial productivity, layoff of industrial units and job cuttings leading to being shaken the financial markets; both equity and debt markets. The prevailing volatility in different financial markets all over the world lead to dent in the capital market performance, challenging mutual fund industries to show consistent performance against the prevailing adverse situation. Mutual Fund Industry was able to go ahead of the market trend. The increasing trend of Indian Mutual Fund Industry bears witness to the fact that it is attracting more and more investors and winning the confidence of the investors. The fund houses are coming with innovative and low-cost products to attract the common masses, so as to contribute towards financial inclusion. The present paper is divided into three parts; the first part highlights the financial inclusion in India, second parts explains the role of mutual funds towards achieving the financial inclusion and third part contains the challenges faced by mutual funds and the action plan necessary to be taken by mutual fund industry to bring financial inclusiveness. Keywords: Financial Crisis, Mutual Fund, Financial Inclusion, Layoff, Volatility.

Landfill site choice in an urban region is a perilous subject in the urban planning process because of enormous impact on the economy, ecology, and the environmental health of the region with the growth of the urbanization, larger amount of wastes are produced and unfortunately the problem gets bigger every day. A selection of appropriate waste discarding site is a function of many factors can be involved under the Environment, Planning & Social Functions. GIS based mapping and succeeding image analysis is projected to be done for each of the correlating criteria for each parameter. The fuzzy multi standards decision making (FMCDM) is used to rank diverse land fill sites based on decisions given by a group of experts. The selected site can be more confirmed through GIS request. This paper emphasizes the clarified approach.

The Western Ghats is one of the 34th Mega Biodiversity hot spots at the global level due to its high number of endemic plant and animal species. That plant species, especially the endemics, have been reported and published in Red Data Book. Heterostemma dalzellii Hook. belongs to the family Apocynaceae is a twining undershrubs species, it is endemic to Western Ghats of India. The present distribution of H. dalzellii is only in India and it is restricted to the Diu, Daman, Dadar- Nagarhaveli, Maharashtra, and Goa. Recently discovered in the southeast Gujarat region. IUCN provided the status of many plants which are present in the Western Ghats. But due to the unavailability of the data, these plant is not appearing in IUCN data. There is an urgent need to evaluate their status as per IUCN categories as well as to undertake conservation measures to protect the habitat of the species. The major goal of the species recovery programme will be to re-establish the populations within their historical range. Their taxonomy will be reinvestigated to confirm their taxonomic distinctness. Population parameters will be collected for each population. H. dalzellii is one of the species that need to evaluate as per the IUCN category because of lacking primary and secondary data. In the present study, I am generating primary and secondary data for the purpose of standing a species in the IUCN category.

In recent time, copper nanoparticles (Cu-NPs) are versatile nanomaterials that find wide array of utilizations in biomedicine, molecular biology, dentistry, dye degradation, catalysis, among others. The aim of this study is to assess the quality of Cu-NPs synthesized from copper tailings and reagent grade copper salt. Chemical reduction method was used to synthesize Cu NPs from copper tailings and reagent grade copper salt using sodium tetrahydroborate (NaBH4) as the reducing agent. The synthesized copper nanoparticles were characterized using different analytical techniques such as: quantitative X-ray Diffraction (XRD), scanning electron microscopy (SEM), X-Fluorescence spectroscopy (XRF), Brunauer-Emmett-Teller (BET), Fourier Transform Infrared Spectroscopy (FTIR) and Thermogravimetric analysis (TGA). The results of XRD identified three major mineral phases tenorite Syn, garnet and quartz in tailing (87.3%, 7.8%, and 4.9%) and reagent grade salt (90%, 6%, and 4%) respectively and confirmed the formation of face-centered cubic (FCC) metallic copper. SEM revealed irregular shape particle morphology with rough surface and particle of 31.3 nm for Cu tailings and 37.6 nm for Reagent Cu nanoparticles. XRF revealed high elemental composition of copper in both synthesized nanoparticles from tailings and reagent salt with 85.15% and 85.98% respectively, BET surface area are 342.11 m2/g and 464.95 m2/g for Cu tailings and reagent salts respectively, and FTIR revealed the specific functional groups O-H, C=O, C-O and Cu-O stretching for both tailings and reagent grade Cu-NPs. However, this type of study has not been reported in an accredited journal. Thermogravimetric analysis (TGA) confirms the thermal stability of these Cu-NPs up to 325 °C. In conclusion, synthesized TCu-NPs and and RCu-NPs were pure, highly crystalline, nano-sized and the quality of the nanoparticles from tailings was slightly lesser than the reagent grade salt due to the presence of impurities. KEYWORDS: Copper tailing, reagent grade copper salt, chemical reduction, copper nanoparticles, characterization

An experimental and numerical study of the operation of an adsorption solar refrigerator using the zeolite-water couple is presented. The experimental consists of measuring the solar radiation incident on the collector-absorber, the temperature of the collector-adsorber, of the condenser and the one of the evaporator. The numerical part concerns a modeling and a simulation of the functioning of this refrigeration system. Transfer equations are deduced from thermal and mass balances established at each component of the refrigerator. The Dubinin-Astakhov equation is adopted for the adsorption kinetics of the zeolite-water pair. The results are presented by the evolution over time of the temperatures of the components of the solar refrigerator (absorbent plate, condenser, evaporator, etc.), as well as the pressure adsorbed, adsorbate mass and SCOP.
