Research paper thumbnail of Efficacy of Homeopathic Medicines to treat Covid-19 diseases

Although WHO recommended three vaccines against Covid-19, this does not guarantee complete protection against the human body. Since the virus constantly changes and infects people causing great suffering and death, we must protect ourselves by following specific hygiene rules. This study showed the effectiveness of Homeopathic Remedies as the alternative treatment for Covid-19. Samples (suspected and confirmed patients of Covid-19) were given homeopathic medicines, and the results were recorded. This study aims to demonstrate a global effort to control the coronavirus (COVID-19) through alternative therapies. National health systems should promptly endorse the efficacy of validated homeopathic treatments to treat the Covid-19 disease as alternative medicine.

Research paper thumbnail of MALAYSIAN JOURNAL OF ANALYTICAL SCIENCES SEASONAL VARIATION AND ECOLOGICAL RISK ASSESSMENT OF HEAVY METAL CONTAMINATION IN SURFACE WATERS OF THE GANGES RIVER (NORTHWESTERN BANGLADESH

Concentrations of Cr, Pb, Ni, Cd, As, Cu and Zn in surface water samples were determined by Flame Atomic Absorption Spectrophotometry. The level of heavy metals did not exceed the permissible limits of drinking water according to Department of Environment (DOE), Bangladesh and World Health Organization (WHO). Only Cr and Cd concentrations exceeded the permissible limits for aquatic life standards of the United States Environmental Protection Agency (USEPA) and Canadian Council of Ministers of the Environment (CCME). The heavy metal pollution index (HPI) showed that the seasonal contamination level followed the order: summer (136.13 (DoE), 220.72 (WHO) and 163.95 (USEPA, CCME)) > winter (57.38 (DoE), 91.36 (WHO) and 72.81 (USEPA, CCME)) > monsoon (16.49 (DoE), 25.36 (WHO) and 19.44 (USEPA, CCME)). Additionally, the HPI value crossed the critical index value (100) for drinking and aquatic life standard during summer season. The metal index (MI) value showed that the water was moderately (DoE), strongly (WHO) and seriously affected (USEPA, CCME) by heavy metals during summer season (3.15, 4.79 and 9.99 according to DoE, WHO and USEPA, CCME, respectively). While the ecology of the river is presently at low risk, this study suggests taking necessary measures to prevent the present pollution rate of contaminants from rising in the future. Abstrak Kajian ini menilai variasi bermusim pencemaran logam dan indeks risiko ekologi bagi permukaan air di Sungai Ganges (Barat utara Bangladesh). Kepekatan Cr, Pb, Ni, Cd, As, Cu dan Zn dalam sampel permukaan air ditentukan oleh spektofotometri nyalaan serapan atom. Berdasarkan Jabatan Alam Sekitar (DoE) Bangladesh dan Pertubuhan Kesihatan Sedunia (WHO), tahap logam berat tidak melebihi paras yang dibenarkan bagi air minum. Hanya kepekatan Cr dan Cd melebihi had yang dibenarkan untuk piawaian akuatik badan Agensi Perlindungan Alam Sekitar Amerika Syarikat (USEPA) dan Majlis Menteri-Menteri Alam Sekitar Kanada (CCME). Indeks pencemaran logam berat (HPI) menunjukkan bahawa tahap pencemaran bermusim mengikuti susunan: musim panas (136.13 (DoE), 220.72 (WHO) dan 163.95 (USEPA, CCME))> musim sejuk (57.38 (DoE), 91.36 (WHO)

Research paper thumbnail of An approach to open a new arena for blue growth of Bangladesh by mud crab (Scylla serrata) fishery from the Karnafuli River estuary, Chattogram; Bangladesh

Worldwide demands of mud crabs can open an arena for the socioeconomic development of Bangladesh. Bangladesh exports thousands of tons of crab worth tens of millions of US dollars every year into East and Southeastern Asian countries. From the statistical report of DoF, 2017, the part of crabs is 0.34% into the total fish production of Bangladesh. The findings of the study revealed that during the mud crab catching season from February - May (4 months), one mud crab catcher’s daily income Taka. 4500 - 7350 which is greater than other districts of Bangladesh. Wild mud crab catching is a seasonal profession. Subsequently mud crab catchers livelihood is very difficult and they fight with economical poverty during off season from June - January (8 months).Wild mud crab catching from Karnafuli River estuary may become a profitable export item, which needs proper support from relevant policy makers.
