Elastic scattering, density distribution, Optical model, cluster model. ,Physics ,QC1-999 - Abstract
Elastic scattering cross sections are a fundamental aspect of nuclear physics research, and studying the cross sections of various nuclei can provide important insights into the behavior of nuclei. In this study, the elastic scattering cross sections of 10C projectile by 27Al, 58Ni, and 208Pb target nuclei are analyzed. The aim of this study is to investigate the cluster structure of 10C and the sensitivity of the elastic scattering cross sections to different potentials. To achieve this objective, the double folding optical model and a simple cluster approach are used to analyze the cross sections. The real part of the optical potential is obtained by folding two different effective interactions, Michigan-3-Yukawa (M3Y) and JeukenneLejeune-Mahaux (JLM), with four different cluster density distributions of the 10C nucleus: 6Be + \alpha, 9B + p, 8Be + p + p, and \alpha + \alpha + p + p. The imaginary part is taken to be a Woods-Saxon phenomenological form. The sensitivity of the elastic scattering cross sections to different potentials is assessed by comparing the results obtained using different potentials. The cluster structure of 10C is validated by comparing the theoretical results with experimental data. The results show that the cross sections are sensitive to the choice of potential used and that the cluster structure of 10C is validated. The theoretical results show reasonable agreement with the experimental data.

- Abstract
In this study, we investigated the production of Au isotopes through neutron transfer reactions in the
48 Ca +197 Au collision at a beam energy of 300 MeV. The reaction products of197±x Au were captured and stopped within an assembly of Au targets after being irradiated with a48 Ca beam. The populated Au isotopes were identified through gamma decay spectroscopy and production cross-sections were determined. Furthermore, we performed model calculations based on the solution of the time-dependent Schrödinger equation for neutrons. These calculations aimed to estimate the formation probabilities and cross-sections of the measured Au isotopes and to elucidate the dynamics of the neutron transfer process. To describe the cross sections of neutron transfer channels and compare with the results of calculations within the framework of the model based on the time-dependent Schrödinger equation, calculations using the Grazing code were performed.

Elastic scattering cross sections are a fundamental aspect of nuclear physics research, and studying the cross sections of various nuclei can provide important insights into the behavior of nuclei. In this study, the elastic scattering cross sections of
10 C projectile by27 Al,58 Ni, and208 Pb target nuclei are analyzed. The aim of this study is to investigate the cluster structure of10 C and the sensitivity of the elastic scattering cross sections to different potentials. To achieve this objective, the double folding optical model and a simple cluster approach are used to analyze the cross sections. The real part of the optical potential is obtained by folding two different effective interactions, Michigan-3-Yukawa (M3Y) and JeukenneLejeune-Mahaux (JLM), with four different cluster density distributions of the10 C nucleus:6 Be + \alpha,9 B + p,8 Be + p + p, and \alpha + \alpha + p + p. The imaginary part is taken to be a Woods-Saxon phenomenological form. The sensitivity of the elastic scattering cross sections to different potentials is assessed by comparing the results obtained using different potentials. The cluster structure of10 C is validated by comparing the theoretical results with experimental data. The results show that the cross sections are sensitive to the choice of potential used and that the cluster structure of10 C is validated. The theoretical results show reasonable agreement with the experimental data. [ABSTRACT FROM AUTHOR]- Published

The elastic scattering angular distributions of the weakly bound Be projectile by Al, Zn, Y, Sn, and Pb target nuclei at various incident energies are analyzed within the framework of optical model-based double-folding model. The aim is to examine the sensitivity of the elastic scattering cross sections to different density distributions of the projectile nucleus. For this purpose, the real part of the optical potantial was obtained for five different projectile density distributions, namely Moszkowski, Gupta 1, Gupta 2, Schechter, and Ngô–Ngô density distributions. The imaginary part is taken as the Woods-Saxon potential. The theoretical results are in good agreement with the experimental data. [ABSTRACT FROM AUTHOR]

Au Benin, les sous-produits consideres isolement presentent des deficiences nutritionnelles ou des caracteristiques physiques qui contrarient leur utilisation. Les blocs multi-nutritionnels (BMN), restent un moyen pour corriger ces contraintes. Ce travail vise a evaluer les caracteristiques physiques et nutritionnelles des BMN fabriques au moyen des sous-produits localement disponibles en utilisant trois types de liants (remoulage du manioc appele " garigo ", l’amidon de manioc " goman " et l’argile). La durete a ete estimee en exercant le pouce au milieu du bloc apres sechage et la cohesion en essayant de le rompre a la main avec un effort plus grand. La couleur a ete appreciee par observation directe des blocs et l’odeur grâce a l’odorat. La composition chimique a ete determinee selon les methodes officielles de l’AOAC et les valeurs nutritives au moyen de la digestibilite in vitro en presence de jus de rumen. Les blocs a base de feuilles sechees de Moringa oleifera ou de tourteaux de coton et dont le liant est " goman " sont de meilleures caracteristiques physiques et nutritionnelles. Il n’y a pas de difference significative au niveau des caracteristiques physiques et nutritionnelles des BMN a base de tourteaux de coton et ceux a base de feuilles de Moringa oleifera . © 2016 International Formulae Group.

Mots cles: Blocs multi nutritionnels, liant, composition chimique, digestibilite in vitro , valeurs nutritives English Title: Physical and nutritional characteristics of multi-nutritional blocks from agricultural and agro-industrial by-products in Benin English Abstract The agricultural and food sector generates numerous byproducts. These offer opportunities for choice of food supplements for ruminants during the dry season when grasses and other herbaceous forage are scarce in rangelands. But, taken separately, these by-products have nutritional deficiencies or physical characteristics that contradict their use. The multi-nutritional blocks (MNB), are a means to address these constraints. Several formulations were tested using three types of binders (middlings of cassava called " garigo " cassava starch " goman " and clay). The hardness was estimated by exerting the thumb in the middle of the block after drying and cohesion under test to break by hand with greater effort. The color was appreciated by direct observation of the blocks and the smell through the smell. The chemical composition was determined according to official methods of AOAC and nutritive values using in vitro gas production. The BMN made from Moringa oleifera leaves or cotton cakes have presented the best physical and nutritional characteristics. It was also noticed that there was no significant difference in the physical and nutritional characteristics of BMN based on cotton cakes or the leaves of Moringa oleifera . © 2016 International Formulae Group.

- Abstract
Several studies have been carried out in the Gulf of Guinea to understand the complex dynamics that control the evolution of tropical coastal environments. The results, based on altimetric and re-analyzes data, revealed the variability of hydrodynamic and morphological processes. These results were validated in the short term with field measurement campaigns. In this paper, we propose a validation of the seasonal and inter-seasonal variability from data collected with a video system installed at Grand Popo, Benin since February 2013 - September 2016. Its potential is assessing event and seasonal coastline behaviour have been demonstrated in a previous study. The video system was used to track the evolution of hydrodynamic parameters and beach's state at high frequency and continuously. A comparison of video estimates is carried out with ERAInterim re-analysis data. The results show a strong correlation between seasonal cycles of hydrodynamic parameters and shoreline's position. However, the qualitative variation of the beach (beach slope) is still strongly linked to other parameters (tide and cross-shore transport processes). During the study period, the Grand Popo beach experienced a gradual decline of its shoreline, reflecting the presence of a strong trend or an inter-seasonal (inter-annual) cycle.

Background Prescription writing is a process which transfers the therapeutic message from the prescriber to the patient through the pharmacist. Prescribing errors, drug duplication and potential drug-drug interactions (pDDI) in prescriptions lead to medication error. Assessment of the above was made in prescriptions dispensed at State Pharmaceutical Corporation (SPC), Anuradhapura, Sri Lanka. Methods A cross sectional study was conducted. Drugs were classified according to the WHO anatomical, therapeutic chemical classification system. A three point Likert scale, a checklist and Medscape online drug interaction checker were used to assess legibility, completeness and pDDIs respectively. Results Thousand prescriptions were collected. Majority were hand written (99.8 %) and from the private sector (73 %). The most frequently prescribed substance and subgroup were atorvastatin (4 %, n = 3668) and proton pump inhibitors (7 %, n = 3668) respectively. Out of the substances prescribed from the government and private sectors, 59 and 50 % respectively were available in the national list of essential medicines, Sri Lanka. Patients address (5 %), Sri Lanka Medical Council (SLMC) registration number (35 %), route (7 %), generic name (16 %), treatment symbol (48 %), diagnosis (41 %) and refill information (6 %) were seen in less than half of the prescriptions. Most were legible with effort (65 %) and illegibility was seen in 9 %. There was significant difference in omission and/or errors of generic name (P = 0.000), dose (P = 0.000), SLMC registration number (P = 0.000), and in evidence of pDDI (P = 0.009) with regards to the sector of prescribing. The commonest subgroup involved in duplication was non-steroidal anti-inflammatory drugs (NSAIDs) (43 %; 56/130). There were 1376 potential drug interactions (466/887 prescriptions). Most common pair causing pDDI was aspirin with losartan (4 %, n = 1376). Conclusion Atorvastatin was the most frequently prescribed substance. Fifteen percent of the prescriptions originate from government sector. SLMC registration number and trade names were seen more in prescriptions originating from the private sector. Most prescriptions were legible with effort. NSAIDs were the commonest implicated in drug class duplication. Fifty three percent of prescriptions have pDDI.

14th International Coastal Symposium (ICS), Sydney, AUSTRALIA, MAR 06-11, 2016; International audience; In this study, we explore the potential of a nearshore video system to obtain a long-term estimation of coastal variables (shoreline, beach slope, sea level elevation and wave forcing) at Grand Popo beach, Benin, West Africa, from March 2013 to February 2015. We first present a validation of the video system with field data over a 10-day experiment conducted on Grand Popo beach in 2014. Secondly, 2-years daily and monthly timeseries are extracted and their variability is described as a function of regional forcing and climatic modes. All variables show large monthly variability. The longshore sediment transport estimated locally from video is in agreement with that derived from Era-Interim wave data re-analyses. Results show that the shoreline responds predominantly to tides at the event scale and to waves. Overall, this study suggests that video stations are efficient tools to monitor coastal processes over the long term, in complement with other conventional approaches. Although no clear conclusions can be drawn on inter-annual variability, the results show that it is important to build up extended coastal observation networks to address coastline changes over a wide range of scales.
