    Photocatalytic Degradation of Organic Dyes Using Nanocrystalline Mg-Co Ferrite

    Jadhav SD* and Patil RS

    DOI: DOI: 10.37421/2684-4923.22.06.168

    The semiconducting Mg-Co ferrite nanoparticles prepared via controlled co-precipitation method. The X-ray diffraction and Transmission Electron Microscopy (SAED patterns) techniques were employed to study phase, composition and the average particle size of the resulting material. The photocatalytic degradation of methyl orange and Congo red dye were performed under illumination of visible light (Philips 250 Watt) as source of photons. The behavior of this reaction was pseudo first order and the maximum photodecolorization efficiency was 85.16% for methyl orange and 95.40 for Congo red in 60 min. at 30°C.

    Deforestation and its Impacts on Climate Change

    Fozia Mujahid

    Introduction: With the increasing availability of ultrasound and concern for malignancy, there has been significant increase in the detection of thyroid lesions. Almost all the cases of thyroid lesions are referred for ultrasound. However, there is no uniformity in the reporting pattern amongst radiologists and hence such ultrasound reports are mostly inconclusive to exclude thyroid malignancy. Therefore, most of the patients have to undergo avoidable Fine Needle Aspiration Cytology (FNAC) or Fine Needle Non-Aspiration Cytology (FNNAC). FNNAC or FNAC is invasive technique which is performed in most of the cases of thyroid nodules to ascertain the type of nodules. The sonographic assessment of thyroid nodule can provide can alternative method to this invasive modality of diagnosis. Therefore, the need was felt for establishing uniformity in ultrasound reporting of thyroid nodules and risk stratification for malignancy with aim of reducing unnecessary FNNAC. TIRADS classification brings uniformity in reporting and reduces ambiguity in management of the patients Objective: To perform comparative evaluation of Thyroid Imaging Reporting and Data System (TIRADS) and cytopathological evaluation of thyroid nodules FNNAC in Indian scenario. Methodology: Multicentric prospective study was conducted in the department of radio diagnosis and department of surgery at defence service hospitals of Hisar and Jaipur during the study period of 01 July 2017 to 31 March 2018. Results: Our study shows high degree of correlation between TIRADS classification and cytopathological evaluation of thyroid nodules. Hence TIRADS can be used an effective tool for avoiding unnecessary FNNAC procedures.

    Consequences of Riverbank Erosion among Rural Household along the River of Meghna in Bangladesh

    M. Shohel Ranaa*, Nilufa Aktara, Kabir Hossaina, Asmaul Hosnaa and Ryan Amita

    DOI: DOI: 10.37421/2684-4923.22.6.172

    Bangladesh, a riverine country, is suffering from acquit riverbank erosion which compels millions of her population to be displaced from their place of origin. Flood and riverbank erosion are dynamic and natural processes which have an adverse impact on livelihood. Our study focuses the socio-demographic profile of the victims of the study area. In our study we have a large number of the respondents receive the formal education that is also 60% of the respondents. Only 10% of respondents who finished the S.S.C. The damage caused by this disaster is a negative cause of illiteracy in the region. About 56% respondent says that river erosion has an impact on their child education. Most often after losing their home they have moved somewhere else therefore their child can’t attend the same school. More than 2 times the people about 54.9% are facing riverbank erosion and 98.8% of them are migrated to another place. After migration 66.4% of them are facing economic crisis and 82.6% of them have changed their occupations due to this calamity. Accommodations, education, treatment, are one of the basic needs which are in great trouble for those areas. Even after so much, only 70% of the people didn’t get any relief. Above all, 88% people believe that such kind of disasters can be solved by constructing embankments. There is a significant association between educational level and tackling erosion. In fact, caused riverbank erosion every year unemployment, landless and poverty are increasing which is responsible to country wide unstable condition.

      Air pollution can cause diseases, allergies, and even death to humans; it can also cause harm to other living organisms such as animals and food crops, and may damage the natural environment (for example, climate change, ozone depletion or habitat degradation) or built environment (for example, acid rain). Plankton produces the oxygen we breathe every day, even every second. In addition to producing oxygen, plankton also remove carbon dioxide from the atmosphere. Blue economy is a term in economics relating to the exploitation, preservation and regeneration of the marine environment. Its scope of interpretation varies among organizations. However, the term is generally used in the scope of international development when describing a sustainable development approach to coastal resources. This can include a wide range of economic sectors, from the more conventional fisheries, aquaculture, maritime transport, coastal, marine and maritime tourism, or other traditional uses, to more emergent spaces such as coastal renewable energy, marine ecosystem services (i.e. blue carbon), seabed mining, and bioprospecting. SWOT analysis identifies internal and external factors that are prioritized by experts in the world blue economic forum domain through an Analytical hierarchy process. The prioritized SWOT factors are used in the formulation of strategies using the TOWS matrix. Regional and international competitive destinations: Local competitors are developing a competitive festival world blue economic to attract tracks of similar profiles big city, improve technology and science and education blue economic.
