técnica de quantis e gerar os balanços hídricos para os diferentes regimes pluviométricos (seco; muito seco; chuvoso; muito chuvoso; normal para o período 1960-2018). Utilizou-se dos dados mensais de precipitações e das temperaturas médias compensadas compreendidas entre o período de 1960 a 2018 da estação meteorológicos convencional do Instituto Nacional de Meteorologia, localizada na latitude 09º04'28"sul e na longitude 44º21'31" oeste, com altitude de 277 metros. Com os dados pluviais anuais, aplicou-se o artifício dos quantis, agrupados os referidos dados de acordo com o regime pluviométrico descrito no objetivo, realizando-se o computo do balanço hídrico pelo método de Thornthwaite Mather, utilizando da capacidade de água disponível o valor de 100 mm. Os procedimentos quantilicos foram essenciais para demonstrar as flutuações pluviais e suas irregularidades nos períodos: seco; muito seco; chuvoso; muito chuvoso e normal. Nos cômputos dos balanços hídricos regionais observaram-se as irregularidades devido a ausência ou o auxílio dos fatores provocadores de chuvas nos períodos estudados. Os excedentes hídricos registraram-se em sua maioria fora do período chuvoso regional e foram ocasionados por eventos extremos com alta intensidade e curta duração de tempo. As deficiências hídricas foram irregulares para os períodos estudados e estão interligados a intensidades dos sistemas provocadores e/ou inibidores das chuvas regionais.

As áreas de preservação permanente (APPs) relacionadas aos recursos hídricos são de fundamental importância para proteção do ambiente e, no Brasil, sua delimitação foi alterada no Código Florestal de 2012, em relação ao Código Florestal de 1965. O objetivo deste trabalho foi avaliar o impacto do Código Florestal de 2012 nas APPs do rio Cabaçal, situado na cabeceira do Pantanal de Mato Grosso. Por meio de geotecnologias foram gerados dois mapas de cobertura vegetal e uso da terra nas APPs dos anos de 2012 a 2018. A mudança na delimitação das APPs em decorrência do Código Florestal de 2012 ocasionou perda de cerca de 90% da APP em relação ao Código Florestal de 1965. Tal área corresponde ao leito maior hidrológico do rio Cabaçal, especialmente no baixo curso, o qual está situado na planície alagável do Pantanal mato-grossense. Essa redução da APP foi em decorrência de que o Código Florestal de 2012 considera a borda da calha do leito regular do curso d'água para a delimitação da APP e não mais o seu nível mais alto. Concluiu-se que ocorreu antropização nas APPs do rio Cabaçal pois a cobertura vegetal foi suprimida para que os usos urbanos e agropecuários fossem implantados.

The Coefficient of Refrigeration Performance and Stress-Assisted Magnetocaloric Effect in Meta-Magnetic Shape Memory Alloys
Authors: Bruno Nickolaus M. 
Published: May 2022

Abstract
Meta-magnetic shape memory alloys (MMSMAs) exhibit multi-physical couplings across a reversible first-order martensitic transition which leads to their potential applications in solid-state cooling, thermally or magnetically driven precision actuation, energy harvesting, and magnetic memory storage. Through their magneto-structural transitions and simultaneous transformation latent heat, MMSMAs are capable of the magnetocaloric effect (MCE) at two distinct operating temperatures (i.e., the critical martensitic transformation temperature and the ferromagnetic Curie point of either the austenite or martensite phase). In this study, the Refrigeration Capacity (RC) and Coefficient of Refrigeration Performance (CRP) in MMSMAs are shown to depend on the critical martensite transformation temperatures and, by extension, uniaxial mechanical stress. A loading sequence, namely the stress-assisted magnetic field-induced phase transformation (SAMFIT) is described, whereby mechanical stress and magnetic field are applied to an MMSMA specimen in sequence to effectively increase the thermal operating range and CRP for a single MMSMA composition.
Tuning Thermo-Mechanical Properties of Shape Memory Polymer Foams for Biomedical Applications

Published: May 2022

Abstract
One application for shape memory polymers (SMPs) is a vessel occlusion plug for peripheral use. The SMP foam used for this device is a low-density material that actuates upon a heat stimulus from the patient's body temperature. The foam plug expands from a small, compressed geometry to a large, expanded plug that conforms to the shape of the cavity in which it is placed. This study explores a different approach to tuning foam thermal and morphological properties than what has been previously investigated. The authors tuned the morphological and thermo-physical properties of shape memory polyurethane/urea foams by adjusting the amount of water, a foaming additive, that was used during material fabrication. The results provide an additional tool for controlling SMP foam properties so that the material may be more suitable for a given application.
Effect of Pre-Strain, Temperature and Time on the Shelf Life Behavior of Nitinol
Authors: Kumar Parikshith K. , Huang Steve 
Published: May 2022

Abstract
Nitinol as a material is often considered stable at temperatures below 100 °C since these temperatures are significantly lower than the theoretical temperature range of [0.3-0.5] Tm (Tm = absolute melting temperature) at which temperature viscoplastic phenomena become active. However, when considering a constrained device, factors such as the peak pre-strain and the associated stress coupled with the exposed temperature and time may have a significant impact on the mechanical behavior of Nitinol. This in-turn can impact the performance and the shelf life of a constrained device. This effort investigates the effect of constant applied uniaxial strain (at different test temperatures over different exposure times) on the superelastic unloading response of Nitinol. To quantify this behavior on a more practical level, tests were conducted by constraining apical samples to different peak bending strains and exposed to an accelerated aging environment. The results from the testing suggest that the tensile response of the Nitinol is impacted by the strain and the time of dwell at a specific temperature under constrained conditions.

Published: May 2022

Abstract
In this paper, the results of different selected mechanical and electrolytic preparation methods are compared with regard to the successful visualization of Nitinol microstructure. The results indicate that a commonly specified preparation route may result in false microstructure and therefore in false interpretation of the material, its behavior, and its lifetime condition. An electrolytic preparation is defined that may provide superior metallographic sample preparation results for drawn NiTi materials.
A Phenomenological Model for the Anisotropic (Positive/Zero/Negative) Thermal Expansion in Shape Memory Alloys and its dependence on Phase Transformation and (Re)orientation of Martensite Variants
Authors: Zhang Mengqian , Baxevanis Theocharis 
Published: May 2022

Abstract
Thermal expansion (TE) is inherent material property and a critical design parameter in applications in which dimensional stability and/or thermal fatigue resistance over a wide range of temperatures are required. Examples include high precision instruments, satellite antennas, and optical instruments. Metallic materials that undergo martensitic transformation have been recently shown to exhibit tailorable bulk TE due to the TE anisotropy of the low-crystallographic-symmetry martensite lattice. In these materials, the TE anisotropy of bulk polycrystals can be exploited through martensite variant "orientation" upon deformation processing. This work proposes a constitutive model for tailoring the anisotropic CTE in shape memory alloys (SMAs) during martensite variant texturing, which is validated against experimental data from NiTiPd. A description of the evolution of the anisotropic macroscopic thermal expansion (TE) tensor of bulk shape memory alloys (SMAs) during phase transformation and martensite (re)orientation is proposed. Given that the tailorability of the TE of SMAs originates from the crystallographic TE anisotropy of the low-crystallographic-symmetry martensite, the TE tensor is approximated by a function of the oriented martensite volume fraction and the orientation direction unitary tensor. The proposed model is validated against recent experiments on tailoring TE through martensite orientation in a NiTiPd high temperature SMA. In those experiments, the TE tensor component in the loading direction of NiTiPd in the martensite state was shown to decrease with increasing inelastic strain induced by uniaxial tensile loading. According to the model, the TE tensor components in the transverse to the loading directions decrease with increasing tensile inelastic strain.
Variation of Material Properties in Tilt-Cast Cu-Al-Ni Alloy

Published: May 2022

Abstract
Alloys based on CuAl have been a promising option for high-temperature SMAs (HTSMA) because of their procedural and cost advantages over NiTi-based high-temperature SMAs. Despite their excellent shape memory as well as phase stability at temperatures up to 250°C, their brittle behavior and the degradation of the shape memory effect under cyclic stress have provided obstacles to widespread application. While multiple remelting processes are often applied to avoid inhomogeneities in the production of these alloys, single step inductive melting is preferable in terms of productivity, especially for small alloy batches. The goal of this and consecutive work is to characterize, and reduce, the variation of material properties and microstructure in materials prepared by vacuum-induction melting of pure elements and tilt-casting. To this end, castings from pure metals with 5 target chemical compositions from Cu12.5wt.%Al4wt.%Ni to Cu13.2wt.%Al4wt.%Ni were prepared and characterized in terms of transformation temperatures and occurrence of martensitic phases. Samples taken from different positions in the casting were compared. Changes in microstructure with increased aluminum content of the alloy could be assessed in both metallographic and calorimetric analysis. Considerable consistency of transformation temperatures and phase composition in each individual casting, as well as between castings with identical parameters, could be achieved. This points to the high degree of homogenization that can be achieved, even with a single melting cycling and subsequent casting, using suitable induction melting parameters. The absence of oxide and carbide inclusions, despite potential reactions between nickel and the graphite of the crucible, is promising for future casting processes.
Wear and Tribology Behavior of Superelastic Ni-Ti Tubes under Fatigue Cycling in Compression

Published: May 2022

Abstract
Compressive loading of shape memory alloys (SMA) is gaining considerable attention in recent years due to the improved fatigue life compared to tensile loading. This can be beneficial in applications such as dampers, actuators, and particularly elastocaloric cooling. SMA elements, however, tend to buckle under compressive loading and their stability can be enhanced by utilizing properly designed holders, i.e., structures that support SMA elements and prevent them from buckling. On the other hand, these supporting structures are in contact with SMA elements, which can cause wear and their premature failure, intensified by the lateral expansion of material under compression. In current literature, a majority of experiments are focused on reciprocating sliding wear of tungsten carbide or variations of bearing steel balls/discs/pins/rings on NiTi plates as well as on comparison of wear performance of NiTi with other materials. The aim of this present work is to theoretically and experimentally study tribological conditions between the tube and supporting element (bushing) and to find the most compatible material to NiTi in order to minimize wear, provide adequate structural support, and finally to enhance the overall fatigue behavior.

Published: May 2022

This paper focuses on a study of natural convection in a Van der Waals gas over a vertical heated plate. An approximate analytical solution of the problem was obtained using an integral method for momentum and energy equations. A simplified form of the van der Waals equation for real gases enabled estimating the effects of the dimensionless van der Waals parameters on the normalized heat transfer coefficient. The effects of the dimensionless Waa and Wab numbers on the normalized Nusselt number in the real gas compared to the ideal gas were estimated. The analysis of the calculation results showed that, with an increase in the Waa number (which characterizes the additional pressure in the real gas), the normalized Nusselt number increases. The effect of additional volume, which shows in an increase in the Wab number, causes a deterioration in the conditions interaction between gas molecules and the wall. This is accompanied by a decrease in the Archimedes force and flow rate in the boundary layer, which leads to a weakening of heat transfer in comparison with an ideal gas.

Published: May 2022

Background: Depressive symptoms are common in Alzheimer’s disease (AD) patients and are associated with an increased functional decline. Selective serotonin reuptake inhibitor antidepressants showed a limited efficacy. Objective: The purpose of this work was to evaluate if a higher brain cholinergic stimulation induced by the association between the acetylcholinesterase inhibitor donepezil and the cholinergic precursor choline alphoscerate has any effect on depression in AD patients. Methods: Patients were selected among those recruited in the ASCOMALVA (association between the cholinesterase inhibitor donepezil and the cholinergic precursor choline alphoscerate in AD) trial. Depressive symptoms were investigated in 90 AD patients through the neuropsychiatric inventory at baseline and after 3, 6, 9, 12, 18, and 24 months of treatment. Patients were randomized in a group association therapy (45 subjects) receiving donepezil 10 mg plus choline alphoscerate 1,200 mg/day, and a group monotherapy (45 subjects) receiving donepezil 10 mg/day plus placebo. Based on the results of the MMSE at the recruitment patients were divided into 3 groups: severely impaired (score < 15); moderately impaired (score 19-16); mild-moderately impaired (score 24-20). Results: Depression symptoms were significantly lower ( p < 0.05) in patients treated with donepezil plus choline alphoscerate compared to patients treated with donepezil alone. Subjects of the group having mild to moderate cognitive impairment were those more sensitive to the association treatment. Conclusion: Depression symptoms of AD patients in the mild to moderate stage probably could to benefit of a stronger cholinergic stimulation induced by associating donepezil with the cholinergic precursor choline alphoscerate.
