Influence of drought stress on phosphorus dynamics and maize growth in tropical ecosystems.

Drought has a significant impact on ecosystem functions, especially on the biogeochemical cycling of phosphorus (P), which is a crucial nutrient for plant growth and productivity. Despite its importance, the effects of different drought scenarios on soil P cycling and availability remain poorly understood in previous studies. This study simulated drought conditions in tropical soils using maize as a test crop under varying field capacity (FC) levels (100%, 80%, 60%, 40%, and 20%) over a 60-day pot experiment.

Correlation analysis of global sagittal alignment of the spine in cases of low-grade degenerative lumbar spondylolisthesis.

Purpose: Disruptions in global sagittal spinal alignment can lead to changes in global sagittal spinal alignment, often manifesting as sagittal malalignment, where the trunk shifts forward. We proposed that these alignment changes are linked to degenerative lumbar spondylolisthesis (DS). The objective was to assess global spinal alignment in low-grade DS using sagittal vertical axis (SVA) classification.

Exploring the impact of Brownian motion on novel closed-form solutions of the extended Kairat-II equation.

This work considers a stochastic form of an extended version of the Kairat-II equation by adding Browning motion into the deterministic equation. Two analytical approaches are utilized to derive analytical solutions of the modified equation. The first method is the modified Tanh technique linked with the Riccati equation, which is implemented to extract some closed-form solutions in the form of tangent and cotangent functions.

Addressing Critical Mistakes in Administering Intravenous Medications at Omdurman Military Hospital, Khartoum, Sudan.

Objective: Errors in the preparation and administration of intravenous medications are significant contributors to morbidity and mortality rates in medical practice. Early reporting and the implementation of preventive measures can mitigate these errors. This study aims to identify patterns and frequencies of errors in IV medication preparation and administration, along with associated factors, at Omdurman Military Hospital in Khartoum, Sudan.

A nationwide provider survey of neuro-oncology tumor boards in a lower-middle-income country: Comparing centers with and without tumor boards.

Objectives: To provide information about implementation, resources, practice patterns and prevalent perceptions regarding neuro-oncology tumor boards (NOTBs) in a lower middle income country.

Methods: A nationwide survey was designed to include licensed neurosurgeons involving data on practice, structure, and perceptions of NOTBs with non-probability sampling, a pre-validated proforma, data analysis using SPSS v27, and geospatial mapping using Quantum GIS.

Results: 139 neurosurgeons were surveyed from 63 neurosurgical centers of a lower middle income country.
