Another Fukushima Nuclear Disaster?

It has been 6 years since the Fukushima Daiichi nuclear disaster in Japan. Do you still remember this energy accident, which was caused by the tsunami following the Tohoku earthquake on March 2001? This accident resulted in the deadly leakage of radiation into the surrounding area, which not only contaminated water and natural environment, but also affected the locals’ health and living condition, so that more than 200,000 residents living nearby had been evacuated. Nowadays, what is the city like? From the relevant news, we know that the Japanese government has taken measures to remove the nuclear fuel in the surrounding area after the disaster and the residents are allowed to Fukushima now, but the city is still desolate and almost no people go back there.
In fact, after the disaster, according to the International Nuclear Event Scale (INES), the Fukushima Daiichi nuclear disaster was classed at the level of 7, the highest level in the Scale, and was considered as the worst nuclear disaster since the 1986 Chernobyl incident. Combined with the present situation of Fukushima, we can predict that the future of the city is not bright and more efforts need to be made for its recovery. However, though there is such a vivid example in our life, the nuclear accidents still take place now and then.
Today, a potential place of the nuclear accident would be introduced. The place is in Armenia, where the Metsamor Nuclear Power Plant (MNPP) is located. And the study analyzed the geological setting, tectonic blocks, faults and volcanism of the MNPP. Then the earthquakes and seismic hazard and risk were also discussed. The result shows that the possibility of nuclear accident in this place is growing and the delay to abandon this Plant might cause another “Fukushima Nuclear Disaster”, which would be a big catastrophe for not only the local people, but also the world.

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 ...

The Influence of Heated Soil in Crop of “Tamaris” Tomato Plants on the Biological Activity of the Rhizosphere Soil

Tomato is a plant with high heat requirements and sensitive to cold weather and frost. The optimum temperature for the growth of tomato plants is between 21˚C and 27˚C during the day and between 17˚C and 21˚C at night. The soil temperature is also very important for plant growth. The optimum soil temperature for tomato cultivation should be within the range 15˚C - 18˚C. Besides, the proper development of the root system depends on the optimal temperature of the soil. A temperature below 14˚C reduces and inhibits the growth of the root system and encourages the development of fungal and bacterial diseases. In this study, the authors aimed to evaluate the effect of heated soil on the population of bacteria, fungi and nematodes inhabiting the soil of tomato cultivar “Tamaris” growing in peat and coconut substrates. The experiment was carried out in 12 treatments and in 3 replications (one slab was one replication). The soils were tested in two different types of containers: cylinders...

Effect of Proline Pretreatment on Grapevine Shoot-Tip Response to a Droplet-Vitrification Protocol

Proline is an α-amino acid that is used in the biosynthesis of proteins. Some studies have shown that proline has been accumulated in plants in response to biotic and abiotic stresses. Exogenous proline has thus been used for improving some plant cryopreservation protocols. Further enhancement of cryopreservation efficiency for  in vitro  grapevines could be expected if stresses linked to cryopreservation procedures could be reduced. In this study, the authors studied the possible beneficial effect of proline in grapevine cryopreservation. Single-node explants from  in vitro  grown grapevine plantlets ( Vitis vinifera  L. cv Portan) were cultured on shooting media (half-strength MS + 1 μM BAP) containing no proline (control) or 50, 500, or 2000 μM filter-sterilized L-proline. Shoot tips excised from these microshoots were subjected to a PVS2-based droplet-vitrification procedure. Control and rewarmed explants were grown on a recovery medium containing ...
