1. Effect of seasons on delirium in postoperative critically ill patients: a retrospective analysis
Abstract Background and objectives Postoperative delirium is common in critically ill patients and is known to have several predisposing and precipitating factors. Seasonality affects cognitive function which has a more dysfunctional pattern during winter. We, therefore, aimed to test whether seasonal variation is associated with the occurrence of delirium

2. A prospective randomized study comparing bipolar plasmakinetic transurethral resection of the prostate and monopolar transurethral resection of the prostate for the treatment of Benign Prostatic Hyperplasia: efficacy, sexual function, Quality of Life, and complications
ABSTRACT Objective: To generate high-quality data comparing the clinical efficacy and safety profile between monopolar transurethral resection of the prostate (M-TURP) and bipolar plasmakinetic resection of the prostate (PK-TURP) for benign prostatic hyperplasia (BPH). Materials and Methods: Prospective, randomized, single-blinded study conducted in a tert

3. Genotype x environment interaction analysis of multi-environment wheat trials in India using AMMI and GGE biplot models
Abstract Fifty wheat genotypes were evaluated at nine diverse locations in India to identify high-yielding and stable genotypes. The analysis of variance based on additive main effects and multiplicative interaction (AMMI) indicated significant genotype, environment and genotype - environment (GE) interactions, with a total variation of 5.99, 20.23 and 73.77

4. Gravity of the non-authorized use of substances not intended for clinical use in invasive aesthetic procedures: the portuguese case
RESUMO INTRODUÇÃO: Os procedimentos estéticos invasivos estão a aumentar globalmente, e são acompanhados por uma apreensão das sociedades médicas sobre a segurança desses procedimentos, dependentes da qualidade e certificação dos prestadores, dos dispositivos e substâncias utilizados e do local onde são efetuados. O presente estudo procura aferi

5. A Numerical Modelling of Mixed Mode Crack Initiation and Growth in Functionally Graded Materials
The main objective of this work is to present a numerical modeling of crack propagation path in isotropic functionally graded materials (FGMs) under mixed-mode loadings. The displacement extrapolation technique (DET) and the maximum circumferential stress (MCS) criterion are investigated in the context of crack growth in functionally graded beam subject to t

6. A Parametric Study on the Centrifugal Force-Induced Stress and Displacements in Power-Law Graded Hyperbolic Discs
Abstract An extensive parametric study on the variation of the centrifugal-force-induced stress and displacements with the inhomogeneity indexes, profile parameters and boundary conditions is conducted based on the author’s recently published analytical formulas for radially functionally power-law graded rotating hyperbolic discs under axisymmetric condit

7. Thermal analysis of steel-concrete composite cross sections via CS-ASA/FA
Abstract When exposed to high temperatures, such as in a fire situation, the physical and resistance characteristics of the materials employed in the structure deteriorate as the temperature increases. This fact promotes a considerable loss in the bearing capacity and stiffness of the structural system. The verification of a structure exposed to fire depends

8. Floristic-functional variation of tree component along an altitudinal gradient in araucaria forest areas, in Southern Brazil
ABSTRACT We aimed to investigate the taxonomic and functional variations of tree component of Araucaria Forest (AF) areas located along an altitudinal gradient (700, 900 and 1,600 m asl), in the southern region of Brazil. The functional traits determined were leaf area, specific leaf area, wood density, maximum potential height and dispersal syndromes and de

9. Parametric Modal Dynamic Analysis of Steel-Concrete Composite Beams with Deformable Shear Connection
Abstract Composite structural elements of steel-concrete began to be used only in 1960 after the development of methods and constructive dispositions that ensured the functionality of these two materials together. In order to verify the importance of the participation of the axial mode in the frequency spectrum of the free vibration problem in composite beam

10. Finite Element Investigation of Performance of Composite-Steel Double Lap Adhesive Joint Under Tensile Loading
Abstract Parametric study of composite-steel double lap joint under tensile loading is performed using finite element modeling. The joint is such that steel is placed between a straight and a curved composite sublaminate. Three joint characteristics including maximum Von Mises stress in adhesive layer, stiffness and weight are investigated. Design curves are

11. Parametric Study of Stay Cables of a Bridge Under Simulated Spatially Correlated Turbulent Wind
Abstract The main objective of this work is to carry out a parametric study of stay cables of a bridge under simulated spatially correlated buffeting forces. This vibration mechanism is simulated with an Autoregressive and Moving Average (ARMA) model, and applied to mathematical models of the stay cables of the tallest cable-stayed bridge in Mexico. The use

12. Machinability Evaluation in Hard Milling of AISI D2 Steel
Milling of hardened steel components provides considerable benefits in terms of reduced manufacturing cost and time compared to traditional machining. Temperature variation in milling is an important factor affecting the wear of cutting tools. The poor selection of milling parameters may cause excessive tool wear and increased work surface roughness. Hence,
