Açai is one of the most consumed foods by the population of Pará, but it generates waste that is not disposed of correctly, which may lead to some socio-environmental impacts. The aim of the present study was to verify the purchase intention of açai seed products by the academic community residing in the metropolitan region of Belém. The research was carried out from May to July 2021 through an electronic form available on the Google Forms platform where the Likert scale was used in the responses, bringing a qualitative and quantitative aspect that presents the following steps: bibliographical research, application of essays and treatment of data using Microsoft Excel ® as a tool for descriptive analysis. The female gender was the respondents in most of the ears. In general, most testimonial participants fully agreed that they perceived the irregular disposal of açai seeds as a deposit on the streets. In the perception of the participants, the main social environments caused by the açai seed are visual smoke, the excess of the seed in rainy seasons and the smoke from watercourses. It is concluded that there was a broad and generalized understanding on the part of the academic community about the situation of the inappropriate disposal of açai seeds, the suggested products made from the stone and açai are accepted by the female and male community of the city of Belém

Tramadol is placed under Drug Controlled Substance Act, in India since 2018, owing to its extensive abuse as a narcotic substance recently. Subsequently, there is increased illegal trafficking across our nation for the drug tramadol. Forensic Science Laboratory, Delhi receives confiscated drugs and toxicological samples for chemical analysis to evaluate their precise composition enabling regulations from law enforcement agencies. Although considered a safe drug for its anti-inflammatory properties when used under medical guidance nevertheless, unintentional fatal tramadol intoxication due to its action on opioid receptors has been reported in several autopsy cases. Contraband tramadol is presently being examined using Gas Chromatography-Mass Spectrometer (GC-MS) and Fourier-transform infrared spectroscopy (FTIR) instrumental techniques in routine forensic examination. In the proposed study, an advanced sensitive technique Gas Chromatography Infrared spectroscopy (GC-IR) was explored as an alternative tool for rapid identification and confirmation. Standard Tramadol was used for method establishment and the method was subsequently applied to seized drug samples and Biological Fluids (blood, and urine samples). Findings of the study indicate that this method can be successfully applied to seized drugs and biological toxicological samples in the forensic examination for the drug Tramadol which was successfully detected by GC-IR. This new rapid analytical method will prove beneficial for the forensic community during routine examination of forensic samples with confirmation.

Tomato is an important vegetable crop grown around the world. Tomato is the most widely cultivated and lucrative vegetable in Ethiopia in particular and in the world in general. It is well known that disease late blight affects tomato crop production and late blight is one of the most devastating diseases of tomatoes worldwide and causes significant loss in production. The objective of this study is to update fruit yield loss assessment data for tomato late blight disease. In this study, 3 treatments were used in a randomized complete block design (RCBD) with three replications. The combined analysis of variance (ANOVA) results for AUDPC and total fruit yield shows significant differences (P<0.05) among treatments. As compared to the unsprayed (control) plot both fungicides significantly controlled the disease at both early and late stage of the crop. The lowest AUDPC (560) was recorded on fungicide Fahem-Gold 72% WP sprayed treatment followed by Mancozeb (752.5). The control treatment (water sprayed) had the highest AUDPC (1592.5). The highest mean fruit yield (16.5 t ha-1) was obtained from fungicide Fahem-Gold 72% WP followed by the standard fungicide (Mancozeb) which gave (8.98 t ha -1) whereas the control treatment gave 4.67 t ha -1. The highest levels of yield loss 71.7% occurred in the unsprayed plots of variety Gulelema as compared to the best protected plot sprayed with Fahem fungicide. Generally, disease and yield parameters indicate that among the two fungicides spray; Fahem was the most effective followed by Mancozeb sprayed plot as compared to unsprayed plots.
