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.

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.

First, the area's most significant environmental threats were identified through questionnaire campaigns run by municipal employees. Hazard maps were created by utilizing a variety of environmental hazards indicators and concentrating on the threats that were primarily perceived by the region's residents, such as deforestation, water pollution and changes in precipitation. After a pair-wise comparison, a GIS environment was used to create an integrated hazard map. The proposed method can be scaled up for integrated environmental hazards analysis in similar regions of Latin America and the maps serve as a first baseline for the analysis of the current state of natural resources in the "Valles Cruceos" area.

The rural region known as "Valles Cruceos" is crucial to the supply of food and other resources to the fast-growing neighboring city of Santa Cruz de la Sierra (Bolivia). The region, like many other rural areas in South and Central America, is experiencing progressive and severe environmental degradation as a result of the growing demand for its natural resources. In this circumstance, sound policies and governance for sustainable land management are ineffective and unsupported by data and research findings. With this study, we want to create a novel and useful integrated hazard analysis method that will help understand hazard patterns based on evidence and inform risk assessment processes across the urban-rural continuum.

There is a great impact on fresh water in the world; this is because of the drastic increase in the human population which leads to the continuous shortage of fresh water. Scientists found various methods to solve this crisis. These include treating industrial wastewater, purifying the seawater, drinking water taken from the ground etc. This review sheds light on the traditional and modern methods applied for this purpose with a focus on the use of natural materials as sustainable and environmentally friendly sources for creating new materials used in this regard. Mainly this review helps to remove the harmful metal arsenic present in industrial waste and groundwater. There are various methods used to remove these particles which are present in the wastewater. Some of the important methods include reverse osmosis, adsorption, extraction, and absorption of the targeted particles using various nanoparticles. Wastewater treatment can be done in three different categories. They are chemical, mechanical, and biological. In this article, we will learn how the metal arsenic can be removed from wastewater by various methods.

The purpose of this study is to promote consistency in national and international charcoal testing protocols. The methods employed for assessing volatile matter and ash content in charcoal are rooted in empirical approaches, exhibiting significant variations across different countries. Within this study, the volatile matter content was gauged under two distinct treatment conditions, namely ISO 562 and ASTM D1762, while ash content was ascertained under two distinct treatment conditions, i.e., ASTM D3174 and ASTM D1762, across varying heating rates. A comparison of various characteristics, including fixed carbon, volatile substance, gross calorific values and ash levels, was done on charcoal samples made from Deer brand charcoal, Coconut sawdust, Palm tree debris and unknown natural products. Variations in volatile matter and ash content were produced by the choice of the technique used. Each criterion demonstrates distinctive qualities that could have an impact on the results. The results indicate a strong correlation between the high volatile content of the charcoals and their low calorific values. Charcoal made from natural products, specifically Indonesian products and Deer brand charcoal have been found to have high calorific values of 31557.2 and 31403.9 KJ/Kg, low volatile matter at 6.47 and 12% and minimal ash content at 2.4 and 2.9%, according to research conducted using the ASTM D1762 technique. Based on the experimental results and different international classification of charcoal, we derived classification criteria and quality index for the quality check of charcoal samples.
