This study aimed to evaluate the tolerance of Psidium guineense Swartz seeds to air-dry storage and priming. Desiccation tolerance was analyzed for seed moisture content of 15%, 10% and 5%. The longevity of seeds during storage was analyzed in seeds with 5% and 10% moisture content maintained in cold and dry chamber (16°C ± 1°C/40% RH), laboratory environment (25°C ± 2°C/60% RH), refrigerator (5°C ± 1°C) and freezer (-18°C ± 1°C) during 90 days, and the priming effect in seeds that were imbibed for 5 or 10 days in polyethylene glycol 6000 at osmotic potentials of -0.3 MPa, -0.5 MPa, -0.7 MPa and -1.3 MPa. The quality of seeds was evaluated after desiccation, storage, and priming by the seeds germination, fresh weight of seedlings, seedlings growth, and germination medium time. The experimental design was completely randomized, with four replications of 25 seeds each one. Although a reduction in seed germination and seedling growth was observed in seeds with 10% and 5% moisture content, drying did not cause complete loss of seed germination and seedling development. Sour guava seeds exhibited an orthodox response to desiccation tolerance and storage. Seed germination and seedling growth were reduced with increased osmotic potential of osmoconditioning. However, conditioning of 10 days increased the seeds germination and optimized the average germination time to 20 days. The seeds of Psidium guineense are able to tolerate desiccation and storage for up to 90 days at a temperature of 5°C ± 1°C and priming for 10 days is a promising technique for propagation of P. guineense.

A Comparison of Methods Used to Determine the Oleic/Linoleic Acid Ratio in Cultivated Peanut (Arachis hypogaea L.)

Cultivated peanut ( Arachis hypogaea L.) is an important oil and food crop. It is also a cheap source of protein, a good source of essential vitamins and minerals, and a component of many food products. The fatty acid composition of peanuts has become increasingly important with the realization that oleic acid content significantly affects the development of rancidity. And oil content of peanuts significantly affects flavor and shelf-life. Early generation screening of breeding lines for high oleic acid content greatly increases the efficiency of developing new peanut varieties. The objective of this study was to compare the accuracy of methods used to classify individual peanut seed as high oleic or not high oleic. Three hundred and seventy-four (374) seeds, spanning twenty-three (23) genotypes varying in oil composition (i.e. high oleic (H) or normal/not high oleic (NH) inclusive of all four peanut market-types (runner, Spanish, Valencia and Virginia), were individually tested ...

Location Optimization of a Coal Power Plant to Balance Costs against Plant’s Emission Exposure

Fuel and its delivery cost comprise the biggest expense in coal power plant operations. Delivery of electricity from generation to consumers requires investment in power lines and transmission grids. Placing a coal power plant or multiple power plants near dense population centers can lower transmission costs. If a coalmine is nearby, transportation costs can also be reduced. However, emissions from coal plants play a key role in worsening health crises in many countries. And coal upon combustion produces CO 2 , SO 2 , NO x , CO, Metallic and Particle Matter (PM10 & PM2.5). The presence of these chemical compounds in the atmosphere in close vicinity to humans, livestock, and agriculture carries detrimental health consequences. The goal of the research was to develop a methodology to minimize the public’s exposure to harmful emissions from coal power plants while maintaining minimal operational costs related to electric distribution losses and coal logistics. The objective was...

Evaluation of the Safety and Efficacy of Continuous Use of a Home-Use High-Frequency Facial Treatment Appliance

At present, many home-use beauty devices are available in the market. In particular, many products developed for facial treatment use light, e.g., a flash lamp or a light-emitting diode (LED). In this study, the safety of 4 weeks’ continuous use of NEWA TM , a high-frequency facial treatment appliance, every alternate day at home was verified, and its efficacy was evaluated in Japanese individuals with healthy skin aged 30 years or older who complained of sagging of the facial skin.  Transepidermal water loss (TEWL), melanin levels, erythema levels, sebum secretion levels, skin color changes and wrinkle improvement in the facial skin were measured before the appliance began to be used (study baseline), at 2 and 4 weeks after it had begun to be used, and at 2 weeks after completion of the 4-week treatment period (6 weeks from the study baseline). In addition, data obtained by subjective evaluation by the subjects themselves on a visual analog scale (VAS) were also analyzed. Fur...
