Mechanical performance and corrosion resistance of reinforced concrete with marble waste

Abstract In this work, the performance of reinforced concrete containing different percentages of marble filler as a partial substitution of ordinary Portland cement is investigated. The cement is replaced by marble accordingly in the range of 5, 10, 15 and 20 wt. % for concrete. The measurements of flexural and compressive strengths are conducted on the concrete with marble dust. The corrosion behaviour of reinforced concrete in the aggressive medium (3% NaCl) is carried out using the potentiodynamic polarisation and impedance spectroscopy. From the outcome of this investigation, the partial substitution of cement by up to 20% of marble in concrete is achieved without compromising the overall strength. For all mixtures, the maximum compressive and flexural strengths at all curing ages are obtained with a 5% replacement of cement by marble. The greater effectiveness of marble waste is attributed to its higher calcium content and CO3 2– ions release, which lead to the formation of carboaluminate hydrates, then to further porosity reduction that increases the strengths. The results also show that the steel bars in reinforced concrete prepared with 5% of marble have better corrosion to that in the ordinary reinforced concrete.
The Practices of HRM, Human Capital, and Organizational Performance: A Literature Discussion in SME Context

SMEs are a very important economic sector in almost all countries. Not only in developed countries but also in developing countries. The reason is, this sector contributes greatly to economic growth, especially to the GDP and employment. Therefore, all governments give a big support to the growth of this sector to contribute even more. The purpose of organizations including SMEs is to increase value for their stakeholders. Therefore, every manager tries hard to improve the performance of his company. In theory, one of the factors that influence organizational performance is HRM practice (Armstrong & Taylor, 2014). However, experts argue that the relationship of HRM practices with organizational performance is an indirect relationship. Therefore, it is important to think about what variables can mediate this relationship. In the literature it is mentioned that human capital can act as a mediating variable in the relationship between HRM practices and organizational performance. However, in the context of SMEs, studies on human capital as a mediator are still rarely found. This present article aims to add to the literature on the mediating role of human capital in the relationship of HRM practices with organizational performance in the context of SMEs.
COVID-19 in cystic fibrosis patients

Since the beginning of the COVID-19 epidemic, the European cystic fibrosis society (ECFS) has decided to launch a special ECFS-COVID-19 program to collect information on the of COVID-19 characteristics in the patients with cystic fibrosis (CF). The results of the program should help timely and efficiently provide the patients with CF with the necessary care. Initially, it was assumed that COVID-19 would be severe in CF patients. The aim. Тo assess the prevalence and characteristics of COVID-19 in patients with cystic fibrosis (CF) in the Russian Federation (RF). Methods. 6 cases (4 children and 2 adults) of COVID-19 in Russian CF patients were analyzed. Results. There are 405,843 infected with SARS-CoV-2 in Russia, the incidence of coronavirus infection in Russia was 1.4 cases per 1 thousand people. According to the Ministry of Health of the RF, as of December 2019, there were 3,931 patients with CF (2,823 children and 1,108 adults). The incidence of COVID-19 was 1.5 per 1000 patients with CF (1.4 : 1,000 for children and 1.8 : 1,000 for adults). The incidence was not higher than in the General population. The diagnosis of COVID-19 was confirmed in 4 boys and 2 women, 3 of the patients were infected with Pseudomonas aeruginosa and 2 – with Achromobacter spp. Mild disease was seen in 5 patients including all the children. Pneumonia was registered in 3 patients. One child with COVID-19 had abdominal syndrome. 2 patients – 1 adult and 1 child – needed in-patient care. Additional antibiotics were given to 4 patients, 2 of them received i/v antibiotics. One adult patient was on the lung transplantation waiting list. This woman had long-term oxygen therapy and BiPAP noninvasive respiratory support before the infection with SARS-CoV-2, FEV1 was 24 %pred. Conclusion. Despite the fact that patients with CF are at risk of severe COVID-19, to date, in the described cases, COVID-19 infection has not led to a significant deterioration of the symptoms of CF. Not a single fatal outcome in Russian patients with CF has been recorded.
IoT-Ready Energy-Autonomous Parking Sensor Device

Finding a free parking lot contributes largely to a total traffic congestion and increases gas emissions in urban and overpopulated cities. Recent advances in smart parking systems adopt Internet of Things (IoT) concepts which tend to improve traffic bottlenecks by providing information about available parking lots. The detection of vehicle presence at the parking lot usually means adopting solutions comprised of power-hungry and battery-operated sensor devices. In this article a hardware-based approach is introduced which aims at building a self-powered and autonomous sensing node equipped with supercapacitors (battery less) to feel the vehicle presence. For purposes of detection, solar-based energy harvester and wake-up trigger prototype is considered along with a Bluetooth low-energy (BLE) radio. The joint use of such technologies is exploited to develop a power autonomous node capable of cost-effectively sensing the car presence and transmitting the parking lot status. The developed triggering system consumes only 150 nA making it suitable as a low-power solution. To initiate the trigger only 6.5 W/m2 in light level change is required comparing the two panels, which is more than adequate as the comparison of solar irradiance measured under the vehicle against diffuse horizontal irradiance shows a significant difference. The developed prototype uses a magnetometer to verify the vehicle presence upon trigger generation and BLE 5.0 technology for status change update, while supercapacitor discharge lifetime duration is estimated to be around 13 days in harsh conditions without charging from solar cells.

Assessing the Impact of Emigration and Remittances on the Economic Growth in Ghana

Workers remittances play a significant role in the lives of receiving households and beneficiaries especially in Ghana. The study employed a time series data spanning from 1990-2018, to assess the impact of Emigration and Remittances on the economic growth in Ghana. There have been contradictory findings in current empirical research on the contribution of workers’ remittances to economic growth. This study discovered that, Emigration and Remittances have a negative impact on the economic growth in Ghana. Actually, most of receiving household spends most of the remitted money on consumption, conspicuous spending and debt repayment rather than investment and savings. Moreover, most remittances receiving families are counterproductive to the labor participation rate in the recipient nations since most of them become reluctant to engage themselves in any productive work as a result of income received from family members abroad, thereby reducing supply of labor and economic cycle. The regression model contains other control variables like Trade, Gross Fixed Capital Formation and Foreign Direct Investment. The main task for the government of Ghana, given the critical position of Emigration and Remittances, is to give and supply opportunities to draw more remittances sent across structured channels and to ensure their effective and efficient usage.
Effect of salt stress on antioxidant enzymes and lipid peroxidation in leaves in two contrasting corn, 'Lluteno' and 'Jubilee'

Salinity is an important problem to crop production; affecting photosynthesis process which favors the production of reactive oxygen species. Plants have generated adaptation strategies to prevent oxidative damage caused by salinity. In this study we evaluated the effect of salinity on lipid peroxidation and antioxidant enzymes in leaves of corn (Zea mays L.) plants 'Lluteno' (adapted to salinity) and 'Jubilee' (improved variety). 'Lluteno' is the only one corn capable to prosper in the Valley of Lluta under saline conditions (EC = 9.1 dS m-1) and the most widely cultivated crop in terms of area in the desert of northern Chile. Plants of 21 d old were subjected for 15 d to two saline treatments: 50 and 100 mM NaCl. Salinity caused a significant reduction in plant biomass, ca. 65% in 'Jubilee' and 20% in 'Lluteno' (P ≤ 0.05). The biomass reduction and oxidative damage to cell membranes caused by the generation of peroxides was significantly less in 'Lluteno'. The activity of superoxide dismutase (SOD), catalase (CAT), guaiacol peroxidase (GPX), and ascorbate peroxidase (APX) in 'Lluteno' was significantly greater than in 'Jubilee' in all treatments, while glutathione reductase (GR) had greater activity in 'Jubilee'. However, most enzymes studied were adversely affected by salinity compared to the control. These results indicate that tolerance to salinity exhibited by 'Lluteno' should in part due to the high activity that exhibit antioxidant enzymes compared to 'Jubilee'.
Profile of bioactive compounds, antioxidant and aromatic component from several clones of cocoa beans during fermentation

Commonly cocoa beans containing various chemical components, nutrients, and bioactive compound. The main bioactive compounds in cocoa beans consisting flavonoids and methylxantines has an positive influence on the health of the human body. Besides the fermented cocoa beans also produce a distinctive of cocoa aromatic. One of the main factors influencing the formation of aroma, chemical content and bioactive compounds of cocoa beans is the fermentation process. The purpose of research is to determine the effect of fermentation duration of cocoa clones with different varieties on the profile of bioactive compounds, antioxidant activity and aromatic components (volatiles) that occur in cocoa beans during fermentation. The treatment was arranged in a Randomized Block Design of two factors, the first factor is cocoa clones (Sulawesi 2/S2 clones and local clones) and the second factor is fermentation time (0, 2, 4 and 6 days). The observed parameters were polyphenol content, antioxidant activity, flavonoid bioactive compounds (catechin and epicatechin) and methylxanthine (theobromin and caffeine), as well as aromatic components (volatile) of fermented cocoa beans. The results of the study was showed that cocoa beans from local clones providing polyphenols, antioxidant activity and bioactive compounds (catechin, epicatechin and theobromine) are higher than S2 clones. While the high caffeine content and distinctive aroma of the pyrazine compound were produced from S2 cocoa beans on 6 days fermentation. The average content of polyphenols, antioxidants and bioactive compounds in non-fermented cocoa beans is higher than fermented beans, but the resulting scent is not strong. The results of the research are expected to obtain information about the profile of bioactive compounds, antioxidants and aromatic components of cocoa beans especially derived from Pinrang district has the potential improving community health.
Removing Pectin and Lignin During Chemical Processing of Hemp for Textile Applications

Pectin and lignin are both very important noncellulosic substances occurring in hemp fibers. The main task in preparing hemp fibers for textile applications is to remove these noncellulosic substances without damage to the fiber cellulose. Pectin and lignin in hemp before and after chemical processing are characterized by infrared spectroscopy. The influence of chemical processes, fiber regions, and alkaline boiling parameters on lignin and pectin removal are investigated in this paper. The results indicate that the alkaline boiling process is effective for removing pectin and lignin. There is no residual pectin in the fibers after the alkaline treatment, but there is a residual level of lignin. The concentration levels of both sodium hydroxide and sodium sulphite have significant effects on lignin removal, and there are variations in lignin properties and accessibility from the lower to the upper regions of the hemp stem.

Investigation of the Effect of the SIRT1 Gene Polymorphisms in Parkinson's Disease

Aim : Parkinson’s disease is a disorder caused by insufficient dopamin production due to the loss of dopaminergic neurons concentrated in the substantia nigra of the brain. Oxidative stress and mitochondrial dysfunction play a central role in the pathogenesis. The Sirtuin1 (SIRT1) gene, shown to protect cells against oxidative stress, has been reported to be associated with predisposition to Parkinson’s disease. In this study, we aimed to investigate the relationship between Parkinson’s disease and the SIRT1 gene polymorphisms rs7895833 and rs2273773. Materials and Methods : The study included 40 patients with Parkinson’s disease (the patient group) and 50 healthy individuals (the control group). The polymerase chain reaction with confronting two-pair primers (PCR-CTPP) and polymerase chain reaction–restriction fragment length polymorphism (PCR-RFLP) methods were used for the rs7895833 and rs2273773 polymorphisms, respectively. Results: For the rs7895833 polymorphism, the genotype distribution for the patient and control groups respectively was as follows: AA (62.5%–53.1%), AG (27.5%–40.8%), GG (10.0%–6.1%). For the rs2273773 polymorphism, the genotype frequencies for the patient and control groups were as follows: TT (90.0%–98.0%), CT (10.0%–2.0%). No statistically significant difference was found between the patient and control groups in terms of rs2273773 and rs7895833 polymorphisms (p>0.05). Discussion and Conclusion : Our findings indicated that the SIRT1 gene polymorphisms investigated did not play a predisposing role in the development of Parkinson’s disease.
The impact of textile relief structures on pressure distribution and heat transport

A long-term static position causes inter alia hypoxia, poor blood circulation, slowing down of the metabolism, and problems in air and heat transport, which in consequence lead to the occurrence of bedsores. In the design of seats and mattresses for people with impaired mobility, advanced textile and composite materials should be used to improve safety and comfort. This functionality can be obtained using spatial textile materials. The aim of the research was to assess the impact of two unmodified woven relief structures I.0 and II.0 made of different yarns and ones modified by inserting linear elements (1: braided round tape and 2: polyethylene tube) to their rib tunnel on the heat transport and on the pressure distribution under loading of 0.5, 1, and 2 N. Element 1 lowers the value of average pressure on the fabrics I.1 and II.1, respectively, by 6.9% and 3.5% at the lowest loading and by 9.8% and 4.6% at the highest loading. For fabric II.2 with element 2, the decrease is of 10.4% and 8.4%, respectively. The thermal conductivity values increase by 8.8%, 9.4%, and 40.1%, respectively for I.1, II.1, and II.2. The pressure distribution and thermal characteristic of the fabrics depend on the type of yarn, the structure of ribs, and the linear element and its fit to the rib tunnel.
A Derivative-Free Liu–Storey Method for Solving Large-Scale Nonlinear Systems of Equations

In this paper, a descent Liu–Storey conjugate gradient method is extended to solve large-scale nonlinear systems of equations. Based on certain assumptions, the global convergence property is obtained with a nonmonotone line search. The proposed method is suitable to solve large-scale problems for the low-storage requirement. Numerical experiment results show that the new method is practically effective.
Quality evaluation of black CTC teas based upon seasonal variations

Summary Effects of seasonal variations on the colour and chemical constituents of Indian black tea were investigated. The experimentation involved collection of different black tea samples that were cultivated at the same tea garden but harvested in three different seasons. Measurement of moisture content was done along with theaflavins (TFs), thearubigins (TRs) and colour (CIE La*b* values) of the brewed tea liquor using spectrophotometric approach. The correlation analysis between chemical constituents, that is, TFs and TRs, moisture content, colour and quality grading was done by using principal component analysis (PCA). The results suggest that quality of tea is dependent upon seasonal variations in terms of chemical changes such as TFs, TRs and moisture content, which also correlate well with colour. The efficacy of the colour of brewed tea liquor in explaining the changes in tea quality due to seasonal variations can be beneficial for scientific fixation of prices at tea auction centres.
Stabilization of lysozyme-incorporated polyion complex micelles by the ω-end derivatization of poly(ethylene glycol)-poly(α,β-aspartic acid) block copolymers with hydrophobic groups

To improve the stability of lysozyme-incorporated polyion complex (PIC) micelles in physiological condition, three types of hydrophobic groups, including phenyl (Phe), naphthyl (Nap), and pyrenyl (Py) terminal groups, were separately introduced to the omega-end of poly(ethylene glycol)-poly(alpha,beta-aspartic acid) block copolymers (PEG-P(Asp)). The goal was to enhance association forces between the enzyme, lysozyme, and PEG-P(Asp) carriers. Introduction of these hydrophobic groups significantly decreases micellar critical association concentration and increases the micellar tolerability against increasing NaCl concentrations. Particularly, PIC micelles formed from PEG-P(Asp) with Py groups was most stable against increasing NaCl concentrations up to 0.1 M. Significant deviation from a spherical shape for the micelles was also observed for the PEG-P(Asp)-Py system, consistent with an increased association number.
Monitoring oxidative metabolism while modeling pancreatic ischemia in mice using a multimodal spectroscopy technique

This paper describes the experimental monitoring of pancreatic oxidative metabolism in laboratory mice that combines the methods of fluorescence and diffuse reflectance spectroscopy and laser speckle contrast imaging with a pancreatic ischemia model. The combined measurements show a close dependence of tissue metabolism on blood and oxygen supply. We show that deactivation of complex I and complex II occurs in mouse pancreatic tissue during prolonged hypoxia. We conclude that complex I can potentially undergo more intensive deactivation when oxygen is lacking than complex II. We have demonstrated that the methods described can be applied in minimally invasive surgery of the pancreas to assess its viability.
Rendering Auto-Antonyms in the Glorious Qur’an

This paper examines rendering auto-antonyms in The Glorious Qur’an in three selected translations of the meanings of The Glorious Qur’an. The term auto-antonyms has been coined to describe a linguistic phenomenon of the Arabic language by which a single word can carry two antonyms. The examples will be selected from The Meaning of the Glorious Qur'an (1930) by Muhammad Marmaduke Pickthall, Interpretation of the Meanings of the Noble Qur'an (1999) by Muhammad Mohsen Khan and Muhammad Taqi al-Din al-Hilali, and Towards Understanding the Ever-Glorious Qur’an by Muhammad Mahmoud Ghali (2003). The examination is achieved by applying Newmark's notion of semantic versus communicative translation and compensation strategies set forth by Dickens, Hervey, and Higgins (2002).
