Use of thermal drone in detection and assessment of larval mass temperature in decomposed rabbit carcasses

Manual ground searches and cadaver dogs are traditional methods for locating remains, but they can be time- and resource-intensive, resulting in the decomposition of bodies and delay in victim identification. Therefore, thermal imaging has been proposed as a potentially useful tool for detecting remains based on their temperature. This study investigated the potential of a novel search technique of thermal drones to detect surface remains through the detection of maggot mass temperatures. Two trials were carried out at Selangor, Malaysia, each utilizing 12 healthy male Oryctolagus cuniculus European white rabbits and DJI Matrice 300 RTK drone China, equipped with a thermal camera; Zenmuse H20T to record the thermal imaging footage of the carcasses at various heights (15, 30, 60–100 m) for 14 days for each trial. Our results demonstrated that the larval masses and corresponding heat emissions were at their largest during the active decay stage; therefore, all the carcasses were observable in thermal images on day 5 and remained until day 7. Statistical analyses showed that (1) no statistically significant differences in thermal images between clothed and unclothed subjects (p > 0.05); (2) 15 m above ground level was proven to be the optimal height, as it showed the greatest contrast between the carcass heat signature and the background (p < 0.005). Our data suggested the potential window of detection of thermal signatures was detectable up to 7 days post-deposition. This could be an important guideline for the search and recovery teams for operational implementation in this tropical region.     

Determination of Acetamiprid and IM‐1‐2 in PostMortem Human Blood,Liver, Stomach Contents by HPLC‐DAD

An HPLC‐DAD method was developed to detect and quantify a neonicotinoid insecticide acetamiprid (ATP) and its metabolite IM‐1‐2 in autopsy samples of a fatal intoxication case. The postmortem blood and tissue distribution of ATP and IM‐1‐2 was determined for the first time. The method showed acceptable precisions and recoveries with relative standard deviations of <10% for ATP level and 1.38 % for IM‐1‐2. The detection and quantification limits for ATP were 0.015 μg/mL and 0.030 μg/mL for blood and were 0.035 μg/g and 0.050 μg/g for liver samples, respectively. The mean contents of ATP were 0.79 μg/g in the liver, 47.35 μg/g in the stomach contents and 2.7 μg/mL in the blood. IM‐1‐2 content was 17.0 μg/g in the stomach contents. ATP and IM‐1‐2 were not detected in the urine. The presence of ATP and IM‐1‐2 in the samples was confirmed by GC‐MS. The method can be exploited in future forensic casework.     

Rapid and nondestructive analysis of lipstick on different substrates using ATR-FTIR spectroscopy and chemometrics

Lipstick can be an important piece of evidence in crimes like murders, rapes, and suicides. Due to its prevalence, it can be an important corroborative evidence in crime reconstruction. The analysis of such evidence can provide an evidentiary link between the suspect, the victim, object, or the crime scene. We report the use of nondestructive ATR-FTIR spectroscopy combined with chemometrics for the classification of 10 brands of lipsticks with nine samples each. Chemometric method of partial least square-discriminant analysis (PLS-DA) has been employed to interpret the data and classify the samples into their respective classes. The PLS-DA model provides an AUC figure above 0.99 in all brands except one; for which it is slightly less at 0.94. We have also tested the traces of these lipstick samples on different substrates treating them as unknowns in the already trained PLS-DA model. 100% of the samples on nine substrates viz. a cotton, nylon, plastic, dry tissue, denim (blue jeans), wet tissue, nitrile gloves, white paper, and polyester were correctly attributed to their source brand. In conclusion, the results suggest that ATR-FTIR combined with the chemometrics is a rapid, nondestructive, and accurate method for the discrimination and source attribution of lipstick. This study has potential for use in actual forensic casework conditions.     

Reforming Indian agriculture and the rise of farmer's protest in India: Tracing the discourse and the way ahead

The Indian government unveiled new farm legislation on September 27, 2020, with the goal of empowering the farming community. According to the government, new farm regulations will reduce the reliance of indigenous farmers on the mandi (market yard) system, which is now in place and is quite exploitative and full of middlemen and legal cartels. The regulations made contract farming lawful with the intention of luring private sector investment in bolstering agricultural supply chains and infrastructure to give farmers better pricing. But these rules are referred to as repressive and anti-farmer by the farming community. Farmers believe that eliminating the mandi system will eliminate the minimum support price (MSP) mechanism and that contract farming will ultimately be damaging, enticing major corporations and private investors to bind them to unfair contracts that will result in exploitation. Farmers' demonstrations have begun as a result in the former territory of the green revolution. In order to determine if the new farm regulations introduced by the central government are indeed beneficial to the rural community or not, the article followed the debate among many academics, policy makers, economists, researchers, stakeholders, and politicians (the government's spokesman). The article's main focus is on analysing the farmers' demand for the new farm rules to be repealed and the economic justification for their opposition. Additionally, it contends that new farm rules will encourage capitalistic farming and endanger the viability of farming communities, particularly small and marginal farms (S&M).

不良资产处置模式创新的制度诉求

我国四大国有资产公司成立近五年 ,对国有银行剥离的约 1 40 0 0亿人民币不良资产的处置已初见成效。实践中 ,资产公司处置这些不良资产时 ,缺乏足够必要的制度资源支持。在处置不良资产时的制度性障碍若不及早消除 ,继续处置不良资产的难度越来越大。本文从革新处置模式的角度探讨如何完善不良资产处置的相关法律法规     

论中国石油行业的反垄断法适用

中国《反垄断法》实施之后,面临对"国有经济占控制地位的关系国民经济命脉和国家安全的行业以及依法实行专营专卖的行业"适用的问题。以石油行业为例,通过反"行政垄断"来推动石油行业的反垄断不应是主导的指向,应当廓清"行政垄断"与依法管制之间的界限,在正确认识石油行业管制体制的形成的前提下,确立政府管制与反垄断法规制之间的协调原则,从结构和行为两个方面有效推进石油行业的反垄断适用。     

农民权益保护视野下我国农村微型金融发展研究

农村微型金融发展体现了对农民生存权、金融权以及发展权的保护和支持。我国农村微型金融发展历经十几年,金融形式不断创新,体现了对农民权益的支持与保护。但是当前我国农村微型金融存在着目标偏离、体系不健全、缺乏法律支持等问题,需要重塑农村微型金融的发展目标和完善农村微型金融体系,促进我国农村微型金融发展。
