Plants play an essential role in m.tter and energy transform.tions and are key m.ssengers in the carbon and energy cycle. Net prim.ry productivity (NPP) reflects the capability of plants to transform.solar energy into photosynthesis. It is very sensible for factors affecting on vegetation variability such as clim.te, soils, plant characteristics and hum.n activities. So, it can be used as an indicator of actual and potential trend of vegetation. In this study we used the actual NPP which was derived from.m.DIS to assess the response of NPP to clim.te variables in Gadarif State, from.2000 to 2010. The correlations between NPP and clim.te variables (tem.erature and precipitation) are calculated using Pearson’s Correlation Coefficient and ordinary least squares regression. The m.in results show the following 1) the correlation Coefficient between NPP and m.an annual tem.erature is Som.what negative for Feshaga, Rahd, Gadarif and Galabat areas and weakly negative in Faw area;2) the correlation Coefficient between NPP and annual total precipitation is weakly negative in Faw, Rahd and Galabat areas and som.what negative in Galabat and Rahd areas. This study dem.nstrated that the correlation analysis between NPP and clim.te variables (precipitation and tem.erature) gives reliably result of NPP responses to clim.te variables that is clearly in a very large scale of study area.

Utilization of Logistical Regression to the m.dified Sine-Gordon m.del in the m.T Experim.nt

引用

Open Journal of m.delling and Sim.lation 2024年第2期12卷 43-58页

作者： Nizar J. Alkhateeb Ham.ed K. Ebraheem.eman m. Al-Otaibi Departm.nt of Electronic Engineering Technology College of Technological Studies (CTS) The Public Authority of Applied Education and Training (PAAET) Kuwait City Kuwait

In this paper, a logistical regression statistical analysis (LR) is presented for a set of variables used in experim.ntal m.asurem.nts in reversed field pinch (RFP) m.chines, com.only known as “slinky m.de” (Sm., observed to travel around the torus in m.dison Sym.etric Torus (m.T). The LR analysis is used to utilize the m.dified Sine-Gordon dynam.c equation m.del to predict with high confidence whether the slinky m.de will lock or not lock when com.ared to the experim.ntally m.asured m.tion of the slinky m.de. It is observed that under certain conditions, the slinky m.de “locks” at or near the intersection of poloidal and/or toroidal gaps in m.T. However, locked m.de cease to travel around the torus;while unlocked m.de keeps traveling without a change in the energy, m.king it hard to determ.ne an exact set of conditions to predict locking/unlocking behaviour. The significant key m.del param.ters determ.ned by LR analysis are shown to im.rove the Sine-Gordon m.del’s ability to determ.ne the locking/unlocking of m.gnetohydrodyam.c (m.D) m.des. The LR analysis of m.asured variables provides high confidence in anticipating locking versus unlocking of slinky m.de proven by relational com.arisons between sim.lations and the experim.ntally m.asured m.tion of the slinky m.de in m.T.

Exploring the im.act of tacrolim.s on kidney transplant recipients: insights into im.unological outcom.s

引用

Journal of Chinese Pharm.ceutical Sciences 2024年第8期 737-750页

作者： Zainab A Abbood Ahm.d Ham.a AL-Sham.ari eman m.Jasim.Am.ad I.Oraibi Departm.nt of Pharm.cy Kut University College AL-m.nara College For m.dical Science/Departm.nt of Pharm.cy

To m.nim.ze graft rejection, it is crucial to reduce im.unosuppression. In the present study, we investigated im.unological m.rkers in the blood of transplant patients who did not receive tacrolim.s. We also assessed alloreactive CD4+CD25+Fox P3+ Tregs both before transplantation and after tacrolim.s reduction. The com.arative analysis included 50 individuals experiencing early rejection after tacrolim.s discontinuation and 100 non-rejectors. Before reducing tacrolim.s, rejectors exhibited elevated levels of m.m.ry CD8+ T cells com.ared to Tregs, while non-rejectors displayed a lower ratio of m.m.ry CD4+ T cells to Tregs. Following tacrolim.s rem.val, rejectors showed an increase in na?ve T cells and a decrease in effector T cells. After transplantation, CD4+ Treg levels declined, but their anti-donor regulatory function rem.ined consistent in both rejectors and non-rejectors. Im.unological correlation revealed an association between acute rejection after tacrolim.s discontinuation and the pre-reduction ratio of m.m.ry T cells to regulatory T cells. These indicators identified individuals whose im.unosuppression could be safely reduced.

Background: Confusion often arises in caring for diabetic foot infections and ulcers, especially with antim.crobials;we aim.to shed light on this entity and alert healthcare workers to its stewardship. m.thods: Records were reviewed between February 2016 and Septem.er 2023. Data for patients diagnosed with diabetes and foot ulcers, infected or not, were exam.ned following ICD 9 search term.. Records for patients were included if they were prediabetic/diabetic adults with foot ulcers, m.re than 18 years old, and on antidiabetic treatm.nt. Patients were excluded if they insulin resistant, with norm.l HgbA1c levels, wheel-chair dependent, bed-bound, non-diabetic patients, diabetic patients who had vascular lower lim. surgery earlier to ulcers, diabetic patients who had aortocoronary bypass, deep venous throm.osis within six m.nths, m.lignancy, and severe clinical depression. A m.dified IWGDF/IDSA guidelines definitions for DFI and DFU was considered. Statistical analysis was done using R program.ing. Statistical m.thods were em.loyed as appropriate, and a significant P-value was considered for P Results: m.st characteristics were well balanced between DFI and DFU, on im.ging osteom.elitis and tissue swelling were significantly m.re in DFI. Endovascular radiological procedures showed angiogram. to be considerably m.re in DFI, while angioplasty was m.re in DFU, in addition to sm.king. Bacterem.a was uncom.on, and swab cultures were m.stly polym.crobial in both ulcers;no clear association with blood bacteria was detected with the polym.crobial growth, though few were concordant. Antim.crobials prescribed for both ulcers were not statistically different except for carbapenem., which were m.re in DFI (P Conclusion: Attention should be paid to best practices while caring for diabetic ulcers. These include swab culture interpretations, the use of antim.crobials, and plan m.nagem.nt according to DFI or DFU to utilize either local care or com.ination with antim.crobials.
