The Implementation of Intensification Buras Chicken to Increase the Fishermen Income
Fisherman family in coastal area is one of the groups who raise chicken in general, because it is easy to take care, eventhough it is still in extensification level. Approach methodology used is bay : (1) Speech and discussion on potency, prospect, and benefit of raising chicken, (2) demonstration and guidance for working chicken coop, ration formula, tetelo vaccination and choosing a new generation, (3) guidance of raising Buras chicken, time after harvesting and marketing, (4) forming a raise chicken group in order to discus in development of business and carrying out their problem. Speech and discussion material presented is positively responded and satisfactory to the participants because there has not yet been carried out such this program. Generally, the participants wanted to adopt and they were active in demonstration on choosing new generation, ration formula, prohibition of disease, taking care of chicken, making of coop and equipment, timing of harvesting and marketing. It would be concluded that the participants who came from Kelurahan Nambo is very enthusiasm and active in this program. Generally, the participants wanted to raise chicken as a primary job as well as their farming.
 
Sickle cell leg ulcers: associations with haemolysis and SNPs in Klotho, TEK and genes of the TGF-beta/BMP pathway
Cutaneous leg ulcers are common in sickle cell anaemia and their risk might be genetically determined. We studied sickle cell anaemia patients to examine the relationship of leg ulcers with haemolysis and with SNPs in candidate genes that could affect sickle vasoocclusion. Leg ulcer patients had lower haemoglobin levels and higher levels of lactate dehydrogenase, bilirubin, aspartate aminotransferase and reticulocytes than did control patients with sickle cell anaemia but without leg ulcers. Age-adjusted comparisons showed that sickle cell anaemia-α thalassaemia was more frequent among controls than cases. These results strongly suggested that the likelihood of having leg ulcers was related to the intensity of haemolysis. Two-hundred fifteen SNPs in more than 100 candidate genes were studied. Associations were found with SNPs in Klotho, TEK and several genes in the TGF-β/BMP signaling pathway by genotypic association analyses. KL directly or indirectly promotes endothelial NO production and the TEK receptor tyrosine kinase is involved in angiogenesis. The TGF-β/BMP signaling pathway modulates wound healing and angiogenesis, among its other functions. Haemolysis-driven phenotypes like leg ulcers could be improved by agents that reduce sickle erythrocyte density or increase NO bioavailability
Evaluation of sustainable electron donors for nitrate removal in different water media
An external electron donor is usually included in wastewater and groundwater treatment systems to enhance nitrate removal through denitrification. The choice of electron donor is critical for both satisfactory denitrification rates and sustainable long-term performance. Electron donors that are waste products are preferred to pure organic chemicals. Different electron donors have been used to treat different water types and little is known as to whether there are any electron donors that are suitable for multiple applications. Seven different carbon rich waste products, including liquid and solid electron donors, were studied in comparison to pure acetate. Batch-scale tests were used to measure their ability to reduce nitrate concentrations in a pure nutrient solution, light greywater, secondary-treated wastewater and tertiary-treated wastewater. The tested electron donors removed oxidised nitrogen (NOx) at varying rates, ranging from 48 mg N/L/d (acetate) to 0.3 mg N/L/d (hardwood). The concentrations of transient nitrite accumulation also varied across the electron donors. The different water types had an influence on NOx removal rates, the extent of which was dependent on the type of electron donor. Overall, the highest rates were recorded in light greywater, followed by the pure nutrient solution and the two partially treated wastewaters. Cotton wool and rice hulls were found to be promising electron donors with good NOx removal rates, lower leachable nutrients and had the least variation in performance across water types.</p
Sedimentary sources of the mud-breccia and mud volcanic activity in the Western Alboran Basin
During the TTR-17 Leg 1 cruise in the West Alboran Basin, gravity cores were acquired from three mud volcanoes (MVs): Dhaka, Carmen and the recently discovered Maya. This paper presents micropaleontological and radiocarbon dating results from the three mud volcanoes, using cores containing mud breccias overlain by and interbedded with hemipelagic sediments. At Dhaka MV, the mud-breccia matrix contains very rare Holocene planktonic foraminifera associated with abundant reworked specimens of mixed Late Cretaceous to Mio-Pliocene age. At Carmen MV, the reworked assemblage is dominated by Miocene to Pliocene foraminifera occurring together with rare Late Cretaceous species while at Maya MV the mud-breccia matrix is characterized by the dominance of Santonian-Maastrichtian forms, with subordinate Tertiary species. Shallow-water benthic foraminifera such as Ammonia spp. and Elphidium spp. are generally rare and randomly distributed, but present at all studied sites. Based on these results, we suggest that the main sediment source of the mud-breccia extruded at Dhaka, Carmen and Maya MVs is possibly the lowermost overpressured olistostromic Unit VI (Aquitanian?-Burdigalian). Differences in the micropaleontological composition of the mud-breccia matrix at different sites are most likely due to differences in the main source layer and in the plumbing systems underneath the MVs. Radiocarbon dating of hemipelagic sediments associated to the mud-breccia allowed to define the age of the latest extrusion activities (>0.27 ka to >15.6 ka BP), which seem to be episodic, short-lived and recurrent over thousands of year
