Platelet Counts and Coagulation Tests Prior to Neuraxial Anesthesia in Patients With Preeclampsia: A Retrospective Analysis

This retrospective, descriptive study aimed to assess hematologic testing practices in 100 patients with preeclampsia undergoing neuraxial blockade (NB). Prior to NB, platelet (PLT) count was performed in 61 (98%) of 62 women in labor and in 37 (97%) of 38 women undergoing cesarean delivery (CD). No patients had a pre-NB PLT count 12 hours. The lack of consistency in pre-NB coagulation testing and the variable time intervals between laboratory tests and NB may be due to a lack of consensus among anesthesiologists for determining “safe” hemostatic conditions for NB placement in patients with preeclampsia

The Impacts of WTO and Water Policy Changes on Saudi Arabian Agriculture: Results from an Equilibrium Displacement Model

Saudi Arabia's food consumption has grown dramatically over time. There has been a sharp increase in food consumption and significant changes in the composition of food consumed. Therefore, it is important that the government of Saudi Arabia anticipate further effects of these changes on growth of food demand and focus on food policies that contribute to development goals. On the other hand, limited agricultural productivity and the nature of the country's climatic conditions have constrained agricultural production. This restricted growth in production, combined with population growth, has led Saudi Arabia to depend heavily on food imports to cover the gap between domestic demand and local production. The increased reliance on imports as a source of food will increase the country's import demand. These main problems facing the Saudi agricultural sector suggest the need for an analytical framework that can evaluate effects of policy and resource change on imports, local production and local demand simultaneously. Ideally, the framework should account for substitution and income effects across products that might arise from changes in consumption and production patterns. This is the main objective of this paper.Food Consumption/Nutrition/Food Safety,

Two-Parameter Differential Calculus on the h-Exterior Plane

We construct a two-parameter covariant differential calculus on the quantum $h$-exterior plane. We also give a deformation of the two-dimensional fermionic phase space.Comment: 7 page

Comparison of Parameters of Lognormal Distribution Based On the Classical and Posterior Estimates

Lognormal distribution is widely used in scientific field, such as agricultural, entomological, biology etc. If a variable can be thought as the multiplicative product of some positive independent random variables, then it could be modelled as lognormal. In this study, maximum likelihood estimates and posterior estimates of the parameters of lognormal distribution are obtained and using these estimates we calculate the point estimates of mean and variance for making comparisons

Advanced channeling technologies for X-ray applications

Recent studies have shown the feasibility of channeling phenomenology applications to describe various mechanisms of interaction of charged and neutral particle beams and radiations as well in solids, plasmas, laser fields - in general, in external electromagnetic fields. As proved, X-rays and thermal neutrons propagation in metamaterials composed by hollow multichannel substance can be much easily analyzed within channeling theory. Its utilization allows predicting some new peculiarities in the radiation distribution behind multichannel subjects that might create novel fine instruments and methods for future applied techniques

Sensitive and specific detection of explosives in solution and vapour by surface-enhanced Raman spectroscopy on silver nanocubes

Surface-enhanced Raman spectroscopy (SERS) has been widely utilised as a sensitive analytical technique for the detection of trace levels of organic molecules. The detection of organic compounds in the gas phase is particularly challenging due to the low concentration of adsorbed molecules on the surface of the SERS substrate. This is particularly the case for explosive materials, which typically have very low vapour pressures, limiting the use of SERS for their identification. In this work, silver nanocubes (AgNCs) were developed as a highly sensitive SERS substrate with very low limit-of-detection (LOD) for explosive materials down to the femtomolar (10−15 M) range. Unlike typical gold-based nanostructures, the AgNCs were found suitable for the detection of both aromatic and aliphatic explosives, enabling detection with high specificity at low concentration. SERS studies were first carried out using a model analyte, Rhodamine-6G (Rh-6G), as a probe molecule. The SERS enhancement factor was estimated as 8.71 × 1010 in this case. Further studies involved femtomolar concentrations of 2,4-dinitrotoluene (DNT) and nanomolar concentrations of 1,3,5-trinitroperhydro-1,3,5-triazine (RDX), as well as vapour phase detection of DNT
