After a few months of studies, a group of geologists from the Ibn Zohr University concludes
PANORAMA OF THE TWO LAKES, A: ISLI LAKE; B: TISLIT LAKE.
that strange lakes, well known in the region Imilchil (Morocco) are the remains of a double impact crater done by a falling meteorite dating from 40,000 years. The aim would be one of the first impact crater discovered in Morocco.
The work done by a scientific team from the Agadir (Morocco), under the direction of Professor Abderrahmane Ibhi ( specialist meteorites ) led to the discovery of other scientific evidence attesting that the two lakes Isli and Tislit correspond , in fact,to impact craters resulting from the collapse of two metal pieces on earth, 40,000 years ago. The diameter of the meteorite fragment resulting Isli Lake is 75 m and a weight of around 1.7 million tons, while that of Tislit would be 50 m and a weight of 950,000 tons. This cosmic event, which released an energy greater than 70 nuclear bombs of Hiroshima type, has certainly influenced the evolution of climate moreover the flora and fauna throughout the region at the time of impact, explains Prof. Abderrahmane Ibhi.
THE FIRST DUAL IMPACT CRATER DISCOVERED IN MOROCCO
(In Abderrahmane Ibhi ‘ research review from Geoheritage and Geomaterials Laboratory, Ibn Zuhr University, published in International Journal of Astronomy and Astrophysics Journal 2013 Vol. A2 by Scientific Research Publishing).
The origin of a double impact crater is explained by the fragmentation of a meteorite entering the earth’s atmosphere into two pieces, the fragments then produce two craters, oriented along the path of the fireball. Double meteorite crater Imilchil is one of the greatest in the world and among the best preserved. Both the scientific and touristic value of this mysterious cosmic training should be among the priorities of Moroccan scientists and managers of tourism in Morocco.View Papers, please click here
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 ...
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...
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 ...
