Authors: Chaudhary R.K. , Devkota A. 
Published: December 2021

The present research was conducted for quantitative study and diversity analyses of aquatic macrophytes dwelling littoral zone of Jagadishpur reservoir, Kapilvastu district in three seasons, as winter (December), summer (April), and rainy (August). Altogether 58 species of macrophytes were recorded in study site, of which highest number of species (54) was occupied by angiosperms followed by three species of pteridophytes and one species of alga. These macrophytes varied in different morphological groups, viz., emergent, submerged, and rooted-floating leaf type. Maximum number of species were represented by emergents (39) followed by rooted-floating leaf type (12) and submerged (7) macrophytes. There was distinct seasonal variation in the distribution of macrophytes: based on importance value index, Nelumbo nucifera (IVI = 22.87), Scripus sp. (IVI = 28.01), Ipomoea carnea (IVI = 24.67) and Typha angustifolia (IVI = 29.01) were dominant in the winter; Nelumbo nucifera (IVI = 20.05), Cynodon dactylon (IVI = 20.07) and Ipomoea carnea (IVI = 21.17) were dominant in the summer and Nelumbo nucifera (IVI = 23.8) and Scripus sp. (IVI =25.56) were dominant in the rainy season. The highest species diversity (H’) of macrophytes was observed during summer (3.451), followed by rainy season (3.135) and winter (3.008). The luxuriant growth of aquatic macrophytes evidenced the highly productive nature of the lake, while the dominance of emergents among the growth forms indicates the encroachment of littoral vegetation, indicating a successional trend toward marsh meadow.

Published: December 2021

Indonesia is known as a maritime state which is associated with marine and fisheries activities. The existence of a harbor, such as the Port of Belawan in Medan City, often causes conflicts in the issue of marine fisheries, especially related to sea pollution. This article investigates the implementation of compensation when traditional fishermen are affected by environmental pollution, especially tankers, its opportunities and challenges in the Indonesian legal context. This study employed a normative and empirical approach, covering the study sites of North Sumatra and Riau Islands Province, which share the border with the Malacca Strait. To date, there are no rules regarding compensation for fishermen, however, there are some embryonic mode such as the existence of experienced human resources from the Environmental Agency of Riau Islands Province in the implementation of compensation for traditional fishermen affected by pollution of the marine environment. This study encourages the local government (i.e., the provincial government) to give more attention related to the compensation for traditional fishermen who are affected by pollution of the marine environment in the form of Regional Regulations or other policies.

Published: December 2021

The Gulf of Mexico is a large, productive, marine and coastal ecosystem providing the coastal residents and neighbouring regions with goods and services. The Gulf of Mexico's water area plays a significant role in shaping the climate across the coastal zone and the thermal state of the region's water also has a major impact on development of atmospheric processes over the Atlantic and Europe. Long-term climate variability throughout the Gulf of Mexico may affect both the strength of the Gulf Stream and heat transfer patterns within the ocean and the economic activity and environmental stability of the entire Northwest Atlantic Region. This work aims at determining the characteristics of variability of temperature regime and salinity of the Gulf of Mexico over recent decades.
The study was conducted based on the Gulf of Mexico Regional Climatology (GOM RC) data, version 2, available at the website of the NOAA's National Centers for Environmental Information (NCEI). It analyzes the temperature and salinity values at different depths for the period of 2005-2017. According to the analysis, over 2005-2017 the spatial distribution of the average annual water temperature on the Gulf of Mexico's surface demonstrates its decrease from south to north. Its highest value is observed next to the northwestern coast of Cuba and along the coastal area of the Bay of Campeche, and the lowest temperature is observed at Apalachee Bay located in the northeastern part of the Gulf of Mexico. Though significant horizontal temperature gradients are observed in winter, during the warm period the temperature field is more homogeneous. The minimum average monthly water temperature on the surface is observed in January, the maximum one – in September. The most distinct seasonal changes in temperature are observed in the water of the northern part of the Gulf of Mexico next to the United States' coast. The distribution of average annual salinity of the most of the Gulf of Mexico is homogeneous with the exception of its northern part, especially in the area where the Mississippi River water flows into it, where salinity decreases sharply. Graphs of water temperature and salinity distribution at different depths across different areas of the gulf were constructed in order to determine the water stratification.

Leading domestic urban planners have devoted their research to the problems of the development of the theory of settlement in Ukraine, the system of settlement and the development of master plans in modern market conditions (1992-2014). Some of them are Filvarov G.K., Yezhov V.I., Demin M.M., Lavrik G.I., Repin V.M., Timokhin V.O., Shkodovsky Y.M., Rudnitsky A .М. and other.
The article presents the stages of formation of production relations, social, economic, architectural and spatial evolution under the pressure of migration processes, based on the analysis and research:

The formation of the labor market (places of employment) in the development of industry, transport links and resettlement (early nineteenth - early twentieth century).
Urbanization of cities in the early twentieth century due to migrations (free labor) from near and far agglomerations.
Urbanization of the late twentieth century due to the release of labor (the collapse of the collective and state farm system).

Under the pressure of migration and transport processes the compositional and planning spatial structure of the city is determined by the following aspects: the hierarchy of the city in the general network of settlements; the level of the city's public transport network; mobility of city residents; location of attractive objects for migrants in the city planning structure; socio-demographic characteristics of residents. Territories of cities with developed production are becoming the poles of industrial industry with the latest technologies, as well as centers of business.

Authors: Oyeka Amechi , Amasiani Rose 
Published: December 2021

This study was carried out to determine the fungal and mycotoxins contamination of 36 Wheat (Triticum aestivium) samples purchased randomly from the seller of the agricultural produce in local markets of Anambra State, Nigeria. Results from the studies showed that two hundred and three fungal isolates consisting of 18 species of moulds and 5 species of yeasts contaminated the wheat samples at varying degrees. For moulds, Aspergillus species contaminated the samples mostly with (28) isolates followed by Penicillum species (19) isolates while Verticillium species and Cladosporium species had equal least contaminations with (3) isolates each. Among the yeast species, Candida rugosahad the highest number of contamination with (37) isolates followed by Cryptococcus laurentii (31) isolates while Candida stellatoides (9) isolates had the least contamination. Twenty-four fungal metabolites were also recovered. The concentration of trichothecene mycotoxin Deoxynivalenol (2067µg/kg), a protein synthesis and cell proliferation inhibitor in animals exceeded the maximum acceptable limits for human consumption. It can be deduced therefore that wheat circulating in Anambra State, Nigeria are variously contaminated with different xerophilic moulds and mycotoxins which can exert adverse health problems to consumers.

Published: December 2021

The skin problem often found on adolescents is acne vulgaris. The pathogenesis of acne vulgaris is multifactorial, from increased production of sebum, hyperproliferation of pilosebaceous follicles, colonization of Cutibacterium acnes, to inflammation process. The elevated sebum production which is often linked to oily skin type could result in acne vulgaris in adolescents. According to Baumann Skin Type, one of the parameters in categorizing skin type is having either oily or dry skin. Acne vulgaris is also found on dry skin. This research aims to find the association between skin types and acne vulgaris. It is an analitic research with cross-sectional method. The data were acquired from 93 students of SMA Santo Thomas 1 Medan who fulfilled the inclusion criteria with stratified random sampling method. The collection of data were primarily carried out with dermatology examination and Baumann Skin Type questionnaire to determine the skin types. Then, they were analyzed with Chi-square test to see the relationship between skin types and acne vulgaris. The obtained results show that 73 (78,5%) out of 93 students suffered from acne vulgaris with predominance being female (39,8%) than male (38,7%), and those in 15-year age group (38,7%). The most commonly observed skin type on samples is oily skin (79,6%). The bivariate analysis with acquired p-value of 0,002 (p<0,05) led to a conclusion that there is a significant association between skin types and acne vulgaris.

Published: December 2021

Background: Melasma and lentigo solaris are common, recurrent, and refractory acquired hyperpigmentation disorder. In spite of variety of therapeutic options available for this cosmetically disfiguring condition, the treatment of this condition remains a challenge. Azelaic acid (AA) is a depigmenting agent which acts by inhibition of DNA synthesis and mitochondrial enzymes, thereby inducing direct cytotoxic effects on melanocytes. Glycolic acid (GA) peel is one of the most versatile agents in the treatment of melasma and lentigo solaris. GA peels alone or in combination with topical hypopigmenting agents has shown encouraging results. However, there is paucity of controlled trial demonstrating the efficacy of GA peels in conjunction with topical AA.
Case: A 42-years-old female, works as a street vendor, came with dark brown spots on both cheeks, nose, chin and forehead that spreads to whole face since one year ago. She had a history of using contraceptives. From the dermatological examination, there were multiple well-circumscribed, irregular hyperpigmented macules that asymmetrical, with size ranging from lenticular to plaque on the maxillary, left buccalis, mentalis and frontalis region. We also found a numular dark brown hyperpigmented macules on right zygoma. She was diagnosed with melasma and lentigo solaris. The Melasma Area Severity Index (MASI) score was 25.6, which classified as moderate melasma. She was treated with 20% azaleic acid cream twice a day, broadspectrum sunscreen with SPF 50 and GA 20% peeling.
Result: After 6 weeks of treatment, there were significant improvement in both melasma and lentigo solaris.
