The aim of the current study was to analyze two major pitfalls in forensic entomological casework: delayed evidence sampling and the effect of low-temperature storage of the body. For this purpose, temperature profiles of heavily infested corpses during cooling and cases in which insect evidence was collected both at the scene and during autopsy were evaluated with regard to species composition and development stages found. The results show that the temperature in the body bags remained at higher average temperatures up to 10 °C relative to the mortuary cooler, therefore, sufficient for larval development, with significant differences in temperature between larval aggregations on one and the same body. In addition, we found large differences both in species number, species composition, and the developmental stages found at the scene and during the autopsy. These data and observations underscore the importance of sampling evidence at the scene and recording temperatures throughout the cooling period of a body.

Lychee (Litchi chinensis Sonn.) fruit were harvested at green, pink, and red developmental stages. The fruit of each group were used to determine developmentally and environmentally (chilling) regulated ethylene production. The rate of ethylene production in the fruit was green > pink > red. Storage at either 4 or 10 °C increased C2H4 production as much as 8.6-fold compared with control fruit stored at 25 °C. The green fruit were most responsive to chilling in terms of ethylene production.

It was investigated and analyzed about the species composition of phytoplankton, and their relations to environmental factors sampled in spring, summer and autumn in 2001-2011 in Fuxian Lake (24o 21'~24o 38' N, 102o 49'12 "~102o 57'26"E). The phytoplankton from Fuxian lake included 78 species belong to 41 genera 25 family, 7 phyla. Chlorophyta was predominant, with consisted of 43.5% of total species number. Species number of phytoplankton appeared visible monthly variation. The main predominant phytoplankton species was Mougeotia bloodlei, which accounted for 42.94%~84.94% of total cell density of phytoplankton. The community structures of phytoplankton were consist of Mougeotia bloodlei, Chroococcus spp., Cyclotella spp., Ceratium hirundinella and Dinobryon sertularia.

The Relationship

Surgical procedures involve major risks, as pathogens can enter the body unhindered. To prevent this, most surgical instruments and implants are sterilized. However, ensuring that this process is carried out safely and according to the normative requirements is not a trivial task. This study aims to develop a sensor system that can automatically detect successful steam sterilization on the basis of the measured temperature profiles. This can be achieved only when the relationship between the temperature on the surface of the tool and the temperature at the measurement point inside the tool is known. To find this relationship, the thermodynamic model of the system has been developed. Simulated results of thermal simulations were compared with the acquired temperature profiles to verify the correctness of the model. Simulated temperature profiles are in accordance with the measured temperature profiles, thus the developed model can be used in the process of further development of the system as well as for the development of algorithms for automated evaluation of the sterilization process. Although the developed sensor system proved that the detection of sterilization cycles can be automated, further studies that address the possibility of optimization of the system in terms of geometrical dimensions, used materials, and processing algorithms will be of significant importance for the potential commercialization of the presented solution.
