Furthermore, it briefly overviews recent developments in depositing different copper-based alloys via WAAM process.
Cementless Metal-Free Ceramic-Coated Shoulder Resurfacing
Authors: Pritchett James W.
Published: May 2023

Shoulder resurfacing is a versatile, bone-conserving procedure to treat arthritis, avascular necrosis, and rotator cuff arthropathy. Shoulder resurfacing is of interest to young patients who are concerned about implant survivorship and those in need of a high level of physical activity. Using a ceramic surface reduces wear and metal sensitivity to clinically unimportant levels. Between 1989 and 2018, 586 patients received cementless, ceramic-coated shoulder resurfacing implants for arthritis, avascular necrosis, or rotator cuff arthropathy. They were followed for a mean of 11 years and were assessed using the Simple Shoulder Test (SST) and Patient Acceptable Symptom State (PASS). CT scans were used in 51 hemiarthroplasty patients to assess the glenoid cartilage wear. Seventy-five patients had a stemmed or stemless implant in the contralateral extremity. A total of 94% of patients had excellent or good clinical results and 92% achieved PASS. 6% of patients required a revision. A total of 86% of patients preferred their shoulder resurfacing prosthesis over a stemmed or stemless shoulder replacement. The glenoid cartilage wear at a mean of 10 years was 0.6 mm by a CT scan. There were no instances of implant sensitivity. Only one implant was removed due to a deep infection. Shoulder resurfacing is an exacting procedure. It is clinically successful, with excellent long-term survivorship in young and active patients. The ceramic surface has no metal sensitivity, very low wear, and, therefore, it is successful as a hemiarthroplasty.

Published: May 2023

Ouagadougou and Bobo-Dioulasso remain the two major urban centers in Burkina Faso with an increasing trend in human footprint. The research aimed at analyzing the Land Use/Land Cover (LULC) dynamics in the two cities between 2003 and 2021 using intensity analysis, which decomposes LULC changes into interval, category and transition levels. The satellite data used for this research were composed of surface reflectance imagery from Landsat 5, Landsat 7 and Landsat 8 acquired from the Google Earth Engine Data Catalogue. The Random Forest, Support Vector Machine and Gradient Tree Boost algorithms were employed to run supervised image classifications for four selected years including 2003, 2009, 2015 and 2021. The results showed that the landscape is changing in both cities due to rapid urbanization. Ouagadougou experienced more rapid changes than Bobo-Dioulasso, with a maximum annual change intensity of 3.61% recorded between 2015 and 2021 against 2.22% in Bobo-Dioulasso for the period 2009–2015. The transition of change was mainly towards built-up areas, which gain targeted bare and agricultural lands in both cities. This situation has led to a 78.12% increase of built-up surfaces in Ouagadougou, while 42.24% of agricultural land area was lost. However, in Bobo-Dioulasso, the built class has increased far more by 140.67%, and the agricultural land areas experienced a gain of 1.38% compared with the 2003 baseline. The study demonstrates that the human footprint is increasing in both cities making the inhabitants vulnerable to environmental threats such as flooding and the effect of an Urban Heat Island, which is information that could serve as guide for sustainable urban land use planning.

Authors: Ermakova Elena , Makshakova Olga , Kurbanov Rauf , Ibraev Ilya , Zuev Yuriy , Sedov Igor
Published: May 2023

Uperin 3.5 is a remarkable natural peptide obtained from the skin of toadlets comprised of 17 amino acids which exhibits both antimicrobial and amyloidogenic properties. Molecular dynamics simulations were performed to study the β-aggregation process of uperin 3.5 as well as two of its mutants, in which the positively charged residues Arg7 and Lys8 have been replaced by alanine. All three peptides rapidly underwent spontaneous aggregation and conformational transition from random coils to beta-rich structures. The simulations reveal that the initial and essential step of the aggregation process involves peptide dimerization and the formation of small beta-sheets. A decrease in positive charge and an increase in the number of hydrophobic residues in the mutant peptides lead to an increase in the rate of their aggregation.
Fluoride Adsorption from Aqueous Solution by Modified Zeolite—Kinetic and Isotherm Studies
Authors: Turki Thouraya , Hamdouni Abdelkader , Enesca Alexandru
Published: May 2023

Fluorine is a very common element in the Earth’s crust and is present in the air, food, and in natural waters. It never meets in the free state in nature due to its high reactivity, and it comes in the form of fluorides. Depending on the concentration of fluorine absorbed, it may be beneficial or harmful to human health. Similar to any trace element, fluoride ion is beneficial for the human body at low levels, but as soon as its concentration becomes too high, it is toxic, inducing dental and bone fluorosis. The lowering of fluoride concentrations that exceed the recommended standards in drinking water is practiced in various ways around the world. The adsorption process has been classified as one of the most efficient methods for the removal of fluoride from water as it is environmentally friendly, easy to operate, and cost-effective. The present study deals with fluoride ion adsorption on modified zeolite. There are several influential parameters, such as zeolite particle size, stirring rate, solution pH, initial concentration of fluoride, contact time, and solution temperature. The maximum removal efficiency of the modified zeolite adsorbent was 94% at 5 mg/L fluoride initial concentration, pH 6.3, and 0.5 g modified zeolite mass. The adsorption rate increases accordingly with increases in the stirring rate and pH value and decreases when the initial fluoride concentration is increased. The evaluation was enhanced by the study of adsorption isotherms using the Langmuir and Freundlich models. The Langmuir isotherm corresponds with the experimental results of the fluoride ions adsorption with a correlation value of 0.994. The kinetic analysis results of the fluoride ions adsorption on modified zeolite allowed us to demonstrate that the process primarily follows a pseudo-second-order and then, in the next step, follows a pseudo-first-order model. Thermodynamic parameters were calculated, and the ΔG° value is found to be in the range of −0.266 kJ/mol up to 1.613 kJ/mol amidst an increase in temperature from 298.2 to 331.7 K. The negative values of the free enthalpy ΔG° mean that the adsorption of fluoride ions on the modified zeolite is spontaneous, and the positive value of the enthalpy ∆H° shows that the adsorption process is endothermic. The ∆S° values of entropy indicate the fluoride adsorption randomness characteristics at the zeolite-solution interface.

Published: May 2023

Cholesta-5,7,9(11)-trien-3β-ol (9,11-dehydroprovitamin D3, CTL) is used as a fluorescent probe to track the presence and migration of cholesterol in vivo. We recently described the photochemistry and photophysics of CTL in degassed and air-saturated tetrahydrofuran (THF) solution, an aprotic solvent. The zwitterionic nature of the singlet excited state, 1CTL* is revealed in ethanol, a protic solvent. In ethanol, the products observed in THF are accompanied by ether photoadducts and by photoreduction of the triene moiety to four dienes, including provitamin D3. The major diene retains the conjugated s-trans-diene chromophore and the minor is unconjugated, involving 1,4-addition of H at the 7 and 11 positions. In the presence of air, peroxide formation is a major reaction channel as in THF. X-ray crystallography confirmed the identification of two of the new diene products as well as of a peroxide rearrangement product.

Research on Surface Tracking and Constant Force Control of a Grinding Robot
Authors: Shi Xiaohua , Li Mingyang , Dong Yuehu , Feng Shangyu
Published: May 2023

To improve the quality and efficiency of robot grinding, a design and a control algorithm for a robot used for grinding the surfaces of large, curved workpieces with unknown parameters, such as wind turbine blades, are proposed herein. Firstly, the structure and motion mode of the grinding robot are determined. Secondly, in order to solve the problem of complexity and poor adaptability of the algorithm in the grinding process, a force/position hybrid control strategy based on fuzzy PID is proposed which greatly improves the response speed and reduces the error of the static control strategy. Compared with normal PID, fuzzy PID has the advantages of variable parameters and strong adaptability; the hydraulic cylinder used to adjust the angle of the manipulator can control the speed offset within 0.27 rad/s, and the grinding process can be carried out directly without obtaining the specific model of the surface to be machined. Finally, the experiments are carried out, the grinding force and feed speed are maintained within the allowable error range of the expected value, and the results verify the feasibility and effectiveness of the position tracking and constant force control strategy in this paper. The surface roughness of the blade is maintained within Ra = 2~3 μm after grinding, which proves that the grinding quality meets the requirements of the best surface roughness required for the subsequent process.
Do Science Parks Promote Companies’ Innovative Performance? Micro Evidence from Shanghai Zhangjiang National Innovation Independent Demonstration Zone
Authors: Wei Minming , Dong Baiyu , Jin Pingbin
Published: May 2023

Science parks are considered to be key drivers of innovative economic activities and are important tools for countries and regions to achieve sustainable development. However, there still exists controversy about the positive effect of the science parks on the companies’ innovative performance. In this study, we constructed six hypotheses according to previous studies and tested them in the Shanghai Zhangjiang National Innovation Independent Demonstration Zone to answer two major research questions, i.e., (1) “Do science parks promote companies’ innovative performance?” and (2) “What factors in science parks affect the likelihood and intensity of companies’ innovative performance?”. Specifically, we selected 911 companies within the park and 861 companies outside the park using the coarsened exact matching method and applied the zero-inflated negative binomial model to identify the relationship between the company’s presence within the science park and the company’s innovative performance. Then, we applied the Heckman two-step model to further explore the key impact factors affecting the intensity of the innovation activities of the companies in the park. The results confirmed our first hypothesis that science parks can promote companies’ innovative performance. Moreover, we obtained two other findings. First, if a company is located within a science park, it can greatly improve the probability of innovation of that company, but it does not have any significant impact on the intensity. In other words, science parks promote more innovation among companies lacking innovation experience than those with innovation experience. Secondly, the reason why science parks can promote innovation is the knowledge spillover of innovation supporting institutions and high-tech enterprises in the parks, which is limited to a small geographical range. Our study provided new evidence on the positive role of science parks on companies’ innovative performance and offered a valuable sample for the research of science parks in developing countries. In addition, the policy suggestions we raised have reference value for developing countries to take full advantage of science parks to achieve sustainable development of their innovative economy.

Enciclopédia do Integralismo : o dogma do sigma
Authors: Christofoletti Rodrigo
Published: May 2023

A Enciclopédia do Integralismo surgiu como uma proposta de apresentação ordenada da leitura de mundo dos integralistas. A apresentação desse corpo doutrinal pautou-se pela necessidade de seus escritos parecerem um conjunto coerente e sólido, uma vez que, por meio dele, seus membros pretendiam divulgar suas realizações. Os integralistas comungavam uma leitura particular de mundo, cuja partilha de convicções era o centro de seu ideário, e o fortalecimento do integralismo do pós-guerra esteve intimamente ligado a essa partilha, num período cada vez mais adverso à presença do integralismo no cenário político. Nesse sentido, a delimitação temporal do tema proposto (1957-1961) justifica-se por este período ter colocado em evidência o retorno de sua postura ritualística. Ao se descolar do terreno da mera compilação, o compêndio de 12 volumes suscitou uma indagação: o que permaneceu do integralismo nesse momento de democracia? Algumas das respostas para essas questões puderam ser encontradas na articulação dos acontecimentos ocorridos em finais da década de 1950.

The biomimetic construction of a microstructural–mechanical–electrical anisotropic microenvironment adaptive to the native cardiac tissue is essential to repair myocardial infarction (MI). Inspired by the 3D anisotropic characteristic of the natural fish swim bladder (FSB), a novel flexible, anisotropic, and conductive hydrogel was developed for tissue-specific adaptation to the anisotropic structural, conductive, and mechanical features of the native cardiac extracellular matrix. The results revealed that the originally stiff, homogeneous FSB film was tailored to a highly flexible anisotropic hydrogel, enabling its potential as a functional engineered cardiac patch (ECP). In vitro and in vivo experiments demonstrated the enhanced electrophysiological activity, maturation, elongation, and orientation of cardiomyocytes (CMs), and marked MI repair performance with reduced CM apoptosis and myocardial fibrosis, thereby promoting cell retention, myogenesis, and vascularization, as well as improving electrical integration. Our findings offer a potential strategy for functional ECP and provides a novel strategy to bionically simulate the complex cardiac repair environment.

Women in STEM, Experiences of Mexican Women Scientists
Authors: Sandoval-Palomares Jessica , García-Ramírez Karina Nayeli
Published: May 2023

From a gender perspective, it is important to recognize that sexual differences are distinguished from social constructions based on these differences and, like stereotypes, are learned and transmitted culturally and where, historically, women have gone from exclusion to segregation in the field of science and their contributions to scientific knowledge. Even today, women still constitute a minority in training and professional itineraries in the scientific-technical field. Therefore, a study was oriented to make visible through a transversal analysis, to understand the different forms of discrimination, harassment and violence against women in the scientific field. For this purpose, a data treatment was carried out, such as the self-perception of discrimination and violence, in a measurable way, as well as the domestic chores, where it was observed the tendency of particular tasks such as the support with the children continues to be a task of greater proportion for women, which gives space to the exercise of motherhood and the labor and social discrimination itself. Finally, there were anonymous testimonies of discrimination and violence, from the voice of women scientists. Thus, while recognizing the work of numerous institutions, civil associations, the creation of instruments and departments in universities on gender issues and women's own self-recognition, we know that the task that remains pending is to address from the initial stage of school, the visualization of girls in science, the elimination of barriers that are socially and culturally present, breaking those gender roles and stereotypes that interfere in their training, so that science is neutral, without sex and/or gender, and on equal terms.

The suggested topic is substantiated by solid research on the benefits of interdisciplinary and cross-curriculum learning materials.

The article analyzes the peculiarities of podcasts as a didactic material compared to traditional audio texts used for teaching listening, and studies the ways of using podcasts in teaching English and German to students specializing in management and economics.

Podcasts are deemed more efficient in motivating students, and developing their professional communication skills due to the key benefits they provide: topicality, autonomy, authenticity, versatility and life-to-classroom adjustment potential.

The article provides thorough analysis of websites that publish podcasts in view of their applicability for ESP. The web-resources are divided into ELT and non-ELT. ELT resources provide task sheets to each podcast, adjusted to specific language background of the learners; however, the topics are limited, and thus cannot be viewed as a substantial resource to develop an audio course of English or German. Non-ELT resources are more versatile, field-specific, and provide up-to-date information, news, expert opinion and advice on burning issues of modern economics and management. However, they are not adjusted to ESL students in their linguistic aspect and duration.

The article studies key principles of developing task sheets for podcasts to be used in teaching English and German to students majoring in economics and management.

Oil palm (Elaeis guineensis Jacq.) is a productive plant where every part can be utilized. Not only the flesh and kernels of the palm fruit can be extracted into oil, but the by-products produced during the production process and their waste can also be processed into something useful. One of the zero waste-based palm oil waste processing that is being developed at this time is the use of non-productive oil palm tree trunks during the replanting period, namely by taking the sap. This research is a quasi-experimental study with a factorial experiment design which aims to analyze the quality of palm sap resulting from zero waste-based waste treatment at several variations of tapping time and duration. In this study, there were 2 factors in cross classification, namely factor A (time) and factor B (tapping time). Factor A consists of 2 levels, namely A1: Morning, A2: Afternoon and factor B consists of 3 levels, namely B1: 4 hours, B2: 8 hours, B3: 12 hours. Treatment is a combination of both. To find out the differences in each treatment group, a bivariate test was performed with one way annova test with a 95% confidence level and continued with Duncan's test. The results showed that the combination of tapping time and length of time was significantly different for pH, moisture content, total acid, total solids and alcohol content of palm sap but not significantly different for ash content of palm sap.
