The Globus Toolkit （GT） has been developed since the late 1990s to support the development of serviceoriented distributed computing applications and infrastructures. Core GT components address, within a common framework, fundamental issues relating to security, resource access, resource management, data movement, resource discovery, and so forth. These components enable a broader ＂Globus ecosystem＂ of tools and components that build on, or interoperate with, GT functionality to provide a wide range of useful application-level functions. These tools have in turn been used to develop a wide range of both ＂Grid＂ infrastructures and distributed applications. I summarize here the principal characteristics of the recent Web Services-based GT4 release, which provides significant improvements over previous releases in terms of robustness, performance,, usability, documentation, standards compliance, and functionality. I also introduce the new ＂***＂ community development process, which allows a larger community to contribute to the development of Globus software.

Primary Budd-Chiari syndrome (BCS) is a spontaneously fatal disease characterized by an obstruction of the hepatic venous outflow tract due to thrombosis or a primary disease of the venous wall. The primary form of BCS is extremely rare. This is a disease mainly affecting young adults of both sexes. Clinical manifestations are variable;they can be asymptomatic, acute, or subacute but mostly chronic. Several causes have been identified, such as myeloproliferative syndrome, antiphospholipid syndrome, paroxysmal nocturnal hemoglobinuria, and inherited thrombotic disorders. Data on primary BCS in Sub-Saharan Africa is rare as most publications available are case reports. In these reports, the causes are unknown with poor prognosis in most cases often leading to patient death. We herein present a case report of a male patient diagnosed with a primary BCS at Yaoundé General Hospital (Cameroon) caused by a Protein C deficiency who presented with ascites decompensating liver cirrhosis. Treatment was based on anticoagulants, diuretics and laxatives administration. Two years after the diagnosis, the patient is alive with clinical and paraclinical improvement.

This paper describes an experimental investigation on the flow characteristics within a rotating cylinder containing a rolling bed of sand. The axis of the cylinder was horizontal and there was no axial bulk flow of particles. The velocity field of the gas flowing through the cylinder was measured by hot-wire anemometry. The measurements indicate that the velocity field is asymmetric with respect to a diameter perpendicular to the granular bed. CFD calculations confirm this finding. The gas velocity profiles are crucial in determining heat transfer from gas to solid.

Background: Tenofovir (TFV) is widely used to treat patients with hepatitis B virus (HBV) infection. But kidney abnormalities are the main concern using this drug. Few studies have described the renal impairment due to the TFV in chronic hepatitis B (CHB) in Sub-Saharan Africa. The objective was to evaluate factors associated with renal impairment observed in patients on TFV for CHB. Method: It was a hospital based cross sectional prospective study carried out from June 2023 to July 2023 in Yaoundé (Cameroon) and included any patient treated with TFV for CHB during at least a period of 6 months. For each participant, we collected in the medical report socio-demographic data, clinical data, baseline creatinine, treatment information (type of TFV which was Disoproxil Fumarate (TDF) or Alafenamide (TAF), duration). Then, we collected blood samples to measure serum creatinine and phosphate levels and urine dipstick analysis. Factors associated with renal impairment were assessed with the Odds Ratio. A p value of Results: A total of 60 participants were included. The median age was 44 years [36-55] and median duration of TFV therapy was 17.5 months [11.7-25.7]. The prevalence of reduced eGFR (Conclusion: Kidney function was impaired in some patients receiving TFV for CHB. It should be monitored, particularly after 36 months and for those receiving TDF prodrug.

The levels and partitioning of genetic diversity and inbreeding depression were investigated in Tupistra pingbianensis,a narrow endemic of southeast Yunnan,China,characterized by a naturally fragmented distribution due to extreme specialization on a rare habitat *** genetic diversity and patterns of genetic variation within and among 11 populations were analyzed using amplified fragment length polymorphism markers with 97 individuals across its whole geographical *** levels of genetic variation were revealed both at the species level(P 99 = 96.012%;H t = 0.302) and at the population level(P 99 = 51.41%;H s = 0.224).Strong genetic differentiation among populations was also detected(F ST = 0.2961;θⅡ = 0.281),which corresponded to results reported for typical animal-pollinated,mixed selfing,and outcrossing plant *** result was consistent with mating patterns detected by our pollination *** indirect estimate of gene flow based on θⅡ was low(N m = 0.64).Special habitat and its life history traits might play an important role in shaping the genetic diversity and the genetic structure of this species.A pollination experiment also failed to detect significant inbreeding depression upon F 1 fruit set,seed weight,and germinate rate *** a naturally rare species,*** is not seriously genetically impoverished and likely to have adapted to tolerating a high level of inbreeding early in its history,we propose this species need only periodic monitoring to ensure their continued persistence,but not intervention to remain viable.
