PCR-based genic and microarray-based Diversity Arrays Technology (DArTTM) markers were used to determine genetic diversity in 94 accessions of white lupin (lupinus albus l.) comprising Australian and foreign cultivars, landraces, and advanced breeding lines from Australian breeding programs. A total of 345 (50 PCR-based and 295 DArT-based) polymorphic fragments were identified, which were used to determine the genetic diversity among accessions. Both cluster analysis of bivariate marker data using UPGMA, and principal coordinate analysis, indicated a high level of genetic diversity in the germplasm. Our results showed that both types of markers used in this study are suitable for estimation of genetic diversity. landrace accessions from Ethiopia formed a very distinct and separate grouping with both marker systems. Australian cultivars and breeding lines were clustered together and tended to be distinct from European landraces. These findings will allow breeders to select appropriate, diverse parents to broaden the genetic base of white lupin breeding populations.

The large demand for drinking water in Oumé Department in the Centre western of Cote d’Ivoire is supplied from groundwater sources. This study investigated the geochemical assessment of groundwater quality in Oumé Department by using a hydrochemical approach with graphical and self-organizing maps (SOM) neural network methods. It was carried out for identifying the hydrogeochemical processes related to groundwater quality, conducting a hydrochemical evaluation of the aquifer systems and delineating the various factors controlling the water chemistry and general suitability for drinking purposes. To reach these goals, groundwater was sampled from 91 locations. Results indicated that the groundwater sampled is acid (pH 4.27 - 7.10) and was weakly fairly mineralised with electrical conductivity values obtained in the range of 95 - 1071 μS·cm-1. All calcium (6.8 - 127.59 mg·l-1), magnesium (1.08 - 29.00 mg·l-1), sulphate (0 - 74.9 mg·l-1), chloride (1.2 - 89.8 mg·l-1), sodium (1.2 - 94.27 mg·l-1) and potassium (0.05 - 23.65 mg·l-1) concentrations and almost nitrate concentrations were within of the recent acceptability and healthbased of drinking-water guidelines set by World Health Organization (WHO). Moreover eleven sampling sites only have concentrations of iron above 0.3 mg·l-1 which can stain laundry and cause taste. In the water points, hydrochemical facies was calcium-bicarbonate (Ca-HCO3) type which generally shows less-polluted water quality. Based on pattern analysis, the inter-relationships among the groundwater quality variables due to the contact with different geological formations on the basis of rocks basicity and acidity were extracted and interpreted.

The find for the optimal slide of water to bring to the plot during the irrigated onion crop was important in order to limit the recharge of the water table close to the soil surface. The quantities of water supplied during onion irrigation were estimated from measurements made with a metal crest to the plot positioned at the tertiary canal. The flow rates at the tertiary canal directly irrigating the plot were recorded during irrigation. From this flow rate, the quantity of water supplied to each plot was determined. From then, the performance of the irrigated system in onion cultivation should pass on the management of this water slide at the level of the hydroagricultural facilities. The integrated soil water mass, salinity and water table dynamics monitoring system was used to assess the water requirements of onion following the irrigation. The daily water requirement of onion in the holland soil of the delta was estimated to average 0.45 g/m3. These requirements were varied according to the development stage of the crop. The water level between the ridges was between 6 and 9 mm during irrigation. This was not permanent, it infiltrated between 12 and 18 hours. This type to the stingray irrigation did not favour the arrival of the water table on the surface. The only fluctuations in the water table were observed during the bulb maturation phase. During this phase, the soil water masses were important. The electrical conductivity recorded varied during the campaign. At the beginning of irrigation, it was 3.62 mS/cm on a 30 cm profile, it decreased towards the end of the irrigations to reach 2.06 mS/cm. The quantities of salt recorded on a 30 cm profile varied from one month to the next;they were 0.468 t/ha at the beginning of irrigation (January) and 0.275 t/ha at the end of the campaign (April). From these results we can say that land degradation in the Senegal river delta would be linked to the arrival of salty groundwater on the surface.

It is not more and more, easy to satisfy the important and growing spectrum demands in the context of the static conventional policy spectrum allocation. Therefore, to find a suitable solution to this problem, we are to days observing the apparition of flexible dynamic spectrum allocation methods. These methods that ought to improve more significantly the spectrum use have gained much interest. In fact, the digital dividend due to the change-over from the analog television to the digital terrestrial television must be efficiently used. So the Dynamic Spectrum Access (DSA) can potentially play a key role in shaping the future digital dividend use. In the DSA, two kinds of users or networks coexist on different channels. The first one, known as the primary user, accesses to a channel with high priority;and the second one, known as secondary user has a low priority. This paper presents a dynamic spectrum access protocol based on an auction framework. Our protocol is an interesting tool that allows the networks to bid and obtain on the available spectrum, the rights to be primary and secondary users according their valuations and traffic needs. Based on certain offers, our protocol selects primary and secondary users for each idle channel in order to realize the maximum economic for the regulator or social benefits. We deal with the case in which the offers of the networks are independent one another even if they will share the same channels. We design an algorithm in accordance with our dynamic spectrum access protocol. The algorithm is used here to find an optimal solution to the access allocation problem, specifically to digital dividend. Finally, the results in the numeric section, regarding the three suggested scenarios, show that the proposed dynamic spectrum access protocol is viable. The algorithm is able to eliminate all non-compliant bidders for the available spectrum sharing. We notice that the revenue or social benefits of the regulator is maximized when we

PhSe-Na+ generated in situ by reduction of PhSeSePh, with sodium borohydride on reaction with N-(2-bromoethyl) phthalimide in N2 atmosphere results in the formation of N-[2-(phenylseleno)ethyl]phthalimide (l1). The title compound has been characterized by elemental analysis, FT-IR, 1H and 13C NMR techniques. The crystal structure of l1 has been solved by direct methods and refined by full-matrix least squares. The ligand l1 crystallize in the monoclinic space group. Selenium forms two Se-C linkages, one is due to Se-Calkyl and the other one to Se-Caryl. Further, the ligation reaction of l1 with complex 1 is also explored whose identities are characterized by spectroscopic techniques.

过去20年，ST段抬高心肌梗死（ST—segment elevation myocardial infarction，STEMI）的急诊再灌注治疗发生了翻天覆地的变化。这种治疗方法主要针对发病12小时内就诊的患者，因为人们认定错过这一时间段后疗效就所剩无几。然而，有极少数患者在胸痛发作12小时后才因STEMI就诊。在两项大规模研究中，分别有8．5％和31．3％的STEMI患者在12小时后就诊。现有的随机试验证据提示，在这种情况下行急诊再灌注治疗效果甚微。溶栓治疗协作组织（Fibrinolytic Therapy Trialist Collaboration）报告说，发病12小时后就诊的患者行溶栓治疗不能降低死亡率。依据这些资料，现行的临床实践指南强烈倾向于对12小时内就诊的患者行急诊再灌注治疗，而对12小时后就诊的患者可否采用这种治疗则更为谨慎。溶栓治疗不起作用的部分原因可能是因为溶栓药物无法开放已经闭塞数小时的血管。

Background: Cesarean section (CS) has increased steadily over the last decade, with an estimated one-third of women delivering by cesarean section worldwide. Objective: Our study aimed to investigate the demographic and associated factors influencing vaginal birth after one cesarean (VBAC-1) success focusing on variables like pre-pregnancy BMI, diabetes, hypertension, education, and smoking. Study Design and Methods: In this retrospective study, we analyzed 285 cases (81 unsuccessful VBAC-1, 204 successful VBAC-1) from San Juan City Hospital (Puerto Rico) between January 1, 2019, and December 31, 2020. We used odds ratios and model selection comparison to assess the impact of variables on successful VBAC-1, using a significance threshold of 95% CI. Model selection assessed binomial model combinations using a generalized linear approach to identify key risk factors. Results: Unsuccessful VBAC-1 (a repeat cesarean), was associated with diabetes (OR: 0.376, p = 0.086), hypertension (OR: 0.23, p = 0.006), and university-educated women (OR: 1.372, p = 0.711). High school-educated women had an OR of 3.966 (p = 0.105), while overweight women were 0.481 times more likely to have unsuccessful VBAC-1 (p = 0.041). Significant associations were not found with obesity (OR: 0.574, p = 0.122), underweight/normal (OR: 1.01, p = 0.810), or smoking (OR: 1.227, p = 0.990). Conclusion: Results revealed women with higher education levels, hypertension, or diabetes are less likely to have a successful VBAC-1. Understanding the complex interactions affecting these outcomes is aimed at establishing guidelines for healthcare professionals to conduct systematic risk/benefit assessments. This study lays a foundation for evidence-based practices and policies, offering initial insights into VBAC-1 success factors in Puerto Rico.

From November 2020 to August 2022, the diet of 12 fish species from the Samandeni reservoir was examined in order to describe the diet and the trophic level of each of them. The analysis of this vital function allows a better knowledge of the concerned ecosystem and gives opportunity for its better management. The fish were sampled with gill nets and cast net. A total of 213 stomach contents of individuals belonging to 12 species grouped in 7 families and 10 genera were analysed. Results showed low to medium vacuity coefficients. The preys were mainly composed of fish, insects, detritus, zooplankton and phytoplankton. Variability in the use of resources by individuals was evident. Thus, the 12 species were classified as fish-eating predators, granivorous, zooplanktivorous, insectivorous and filter-feeding microphages. Then, the fish trophic structure of the Samandeni reservoir was elaborated.
