1. Simple and fast process using hydrochloric acid for producing synthetic zinc-rich stevensite
Abstract In the last decades, clays have been used in sectors such as health and cosmetics. This requires products that are increasingly pure and present homogeneous properties, hardly found in natural clays. The use of synthetic clays can be a solution. For this, it is necessary to explore techniques for their production. The main focus of this study was to

4. Dynamic anisotropy and non-linear geostatistics supporting short term modelling of structurally complex gold mineralization
Abstract Non-linear geostatistical methods are known to deal appropriately with the geological and geometrical complexity of gold deposits. This article reports the results related to an investigation to improve the gold content estimate based on restricted ore modeling to honor the structural aspects that control the mineralization. The grade domains are de

5. Efficacy of exercise on balance, fear of falling, and risk of falls in patients with diabetic peripheral neuropathy: a systematic review and meta-analysis
ABSTRACT Diabetic peripheral neuropathy (DPN) is the most common complication of diabetes mellitus. Our objective was to evaluate the efficacy of exercise interventions in DPN patients from randomized controlled trials. The primary outcomes were the risk of falls, fear of falling, balance and quality of life. Two reviewers independently selected studies from

6. Milk heat treatment affects microbial characteristics of cows’ and goats’ “Jben” traditional fresh cheeses
Abstract “Jben” is an Algerian traditional fresh cheese produced from raw or pasteurized milk of cows, goats and sheep, on a small scale during the period of milk abundance in a restricted area of the North-east and -West of Algeria. In this study, four Jben-type cheeses were produced: cheeses made from cow’s milk subjected to 82 °C/10 sec treatment o

7. Illness perception, coping, and quality of life in early-stage Mycosis fungoides,
Abstract Background: Mycosis fungoides is the most common type of cutaneous T-cell lymphoma. Most early-stage mycosis fungoides cases follow an indolent course, hence considered by doctors a relatively easy condition. However, since mycosis fungoides bears the title of cancer, patients might perceive it differently. Objective: To investigate patients’ il

8. COMPUTATIONAL ANALYSIS OF LOAD VENTILATION IN BROILER TRANSPORT
ABSTRACT The characterization of ventilation during the transport of broiler chickens is essential for identifying and characterizing the potential problems of a convective heat flow and its effects on the welfare and the health and production conditions of the chickens. The objective of this study was to evaluate the ventilation patterns in two layout model

9. Hybrid Hydrogels Based on Polyethylene Glycol Bioconjugated with Silylated-Amyloidogenic Peptides
Hybrid-peptide hydrogel arrangements are a promising alternative to obtaining biocompatible structures at the nanoscopic scale. In this work, a new class of hybrid hydrogels was obtained through the sol-gel process based on the reaction between an amyloid-like octapeptide sequence [RF]4 (where R = arginine and F = phenylalanine) covalently bonded with glycin

10. Peculiarities of drilling and blasting in underground small-scale mines
Abstract Artisanal and Small-scale Mining (ASM) is a prominent activity in the extractive industry: considering only gold, it produces about 20% of the world market supply. Despite this fact, ASM is generally associated with the negative aspects of its environ mental impact, and operational research is generally neglected. This article empha sizes the peculi

11. Development of a low-cost alternative for the monitoring of the ore hauling production indicators in small-scale mining
Abstract Small and medium-sized mining represent an important part of a country's min eral economy. These companies, although substantial and numerous, have low invest ment potential in their development through new technologies. One of the problems small and medium mining companies face is the ore hauling production monitoring. This operation alone can cons

12. Adjunctive vortioxetine for SSRI-resistant major depressive disorder: a “real-world” chart review study
Objective: Selective serotonin reuptake inhibitors (SSRIs) are the cornerstone of treatment of major depressive disorder (MDD). However, non-response is common, often necessitating combination strategies. The present study assessed the efficacy of vortioxetine as an add-on therapy in patients with SSRI-resistant MDD. Methods: The charts of 36 adult outpati
