Eugenia roxburghii is an evergreen graceful shrub with a tremendous potential as garden plant. As a part of ex-situ conservation and popularization of the species, seed longevity was studied by understanding the relationship of seed viability with respect to different moisture contents and storage temperature. Seeds are recognized as recalcitrant, being desiccation as well as chilling sensitive. During hermetic storage, seeds stored at 300C/70%RH retained viability for about 5 months and 4 months in 200C/20% RH. Seeds can be best stored for five months in laboratory conditions.

Seeds of Garcinia talbotii remained viable hardly for two weeks in open room conditions. As part of ex-situ conservation of Garcinia talbotii, seeds longevity was studied since seeds are the main propagule. For this, the relationship of seed viability with respect to different moisture content and storage temperature were analyzed. Seed storage behaviour is also investigated. Being recalcitrant, seeds are desiccation sensitive as well as chilling sensitive. During hermetic storage of seeds at 300C /70 % RH seeds retained viability about 6 months.

Abstract A national survey was conducted to ascertain the relationship of the cyclohexylamine content of cyclamate-containing products to their composition, processing, and storage conditions. Cyclohexylamine was found in 174 of the 232 samples examined. The cyclohexylamine content range for each major type of food product was as follows: 0.0–8.2 ppm for carbonated beverages; 0.0–5.8 ppm for dry beverage bases; 0.0–1.5 ppm for fruit juices; 0.0–0.8 ppm for weight control foods; and 0.3–66 ppm for food sweetener preparations (liquid and dry base). No correlation between the cyclamate content of products and the cyclohexylamine present was evident. However, the findings indicate that significant hydrolysis of cyclamate can occur.

Bosc is a winter cultivar of european pear (Pyrus communis) that has a relatively short storage life partially due to a high ethylene production rate (EPR) during cold storage. ‘Bosc’ pears were harvested at commercial maturity and treated with gas 1-methylcyclopropene (1-MCP) at 0, 0.15, and 0.3 µL·L−1 and stored at −1.1 °C for 8 months. Results indicated that all 1-MCP treatments inhibited EPR and respiration rate (RR), retarded the degradation of chlorophyll and titratable acidity (TA), and extended storage quality; but inhibited ripening capacity. 1-MCP at 0.15 and 0.3 µL·L−1 had the same efficacy on keeping fruit quality although its higher rate was more efficient on inhibiting EPR and RR. The expression of ethylene synthesis genes (PcACS1, PcACS2, PcACS4, PcACS5, and PcACO1) and receptor genes (PcETR1, PcETR2, and PcERS1) was upregulated in control fruit during storage and they were downregulated significantly by 1-MCP treatments. In contrast, the ethylene receptor genes of PcETR5 and PcCTR1 were downregulated in control fruit during storage and were unaffected by 1-MCP treatments. Although the transcription levels of chlorophyll degradation genes PcPPH, PcNOL, PcSGR, PcRCCR, PcNYC, and PcPAO were all upregulated in control fruit during storage and downregulated by 1-MCP; only PcCHL was downregulated in the control and 1-MCP had no consistent effect on it. The relationship of ethylene biosynthesis/perception with chlorophyll degradation and storage quality in european pears was discussed.

Abstract The electron microscopic appearance of platelets incubated at 37 C. and stored at 4 C. are described, and the relationship of these changes to normal platelet structure are discussed together with the hypothesis that the observation may be due to lysosome activity of some of the platelet granules. The platelet’s ATP level during incubation and storage was also followed and it was concluded that this relates more to the platelet’s ability to sustain clot retraction than to its viability.

Abstract Emerging technologies are efficient alternatives for satisfying the growing demand for sustainable and cheap energy sources. Piezoelectrics are one of the most promising energy sources derived from emerging technologies. These materials are capable of converting mechanical energy into electricity or vice versa. Piezoelectrics have been used for almost a hundred years to generate electrical and sound pulses. However, the use of piezoelectrics for power generation is constrained by the cost associated with equipment and infrastructure. This problem has been addressed through mathematical models that relate the physical and electrical properties of the piezoelectric material with the voltage generated. Although these models have high performance, they do not incorporate voltage rectification and electrical charge storage stages. This work presents a mathematical model that describes the relationship of the physical and electromechanical properties of a system employing a piezoelectric for energy generation. The voltage of the system and the charge stored in a capacitor are calculated through this model. Also, contour diagrams are presented as a tool for facilitating the efficiency of energy generation.

The relationship of storage time and temperature to loss of infectivity for Trichinella spiralis was evaluated. Ground trichinous pork was stuffed into casings, packed in boxes, and frozen in tiers of five boxes at four selected temperatures. Trichinae became non-infective between 6 to 10 d when stored at −17.8°C and between 11 to 15 d when stored at −12.2°C. Infective trichinae were obtained in final samplings after 56 d of freezing at −9.4°C and 71 d at −6.7°C. Little or no effect on infectivity was evident in trichinae frozen at −6.7°C throughout the 71-d period. Position of the box in the tier was a factor at −17.8°C and −12.2°C, as infectivity decreased more rapidly in top and bottom boxes than in other boxes.
