1. Milling parameters and solid waste characterisation to use as supplementary cementitious materials
Resumo Embora a utilização de matérias-primas residuais como materiais cimentícios suplementares (MCS) seja uma temática crescente na literatura, o processo de beneficiamento por moagem e seus parâmetros ainda são pouco explorados e apresentados.Nesse contexto, o presente estudo visa avaliar os parâmetros de moagem para o beneficiamento dos resíduos

2. Mineral profile and characterisation of cookies made from legume green grain flour
Abstract The aim of this work was to determine and compare the mineral composition and physico-chemical parameters of formulations of cookies developed by hand based on Lablab purpureus (L.) Sweet (mangalo—BFM), Vigna unguiculata (L.) Walp. (cowpea beans—BFC) and Cajanus cajan (L.) Huth (pigeon pea—BFP) flours. The results indicate that the cookies hav

3. Microstructural and mechanical characterisation of the Simon Bolivar's iron bridge structure, 19th century, Arequipa, Peru
Abstract The microstructure of the main structural elements (Phoenix columns, transversal beams and tie-rods) of the Simón Bolivar iron bridge, located in Arequipa (Peru), was investigated. The bridge was supposedly designed by Gustave Eiffel and opened to the public in 1882. The characterisation revealed that the columns, beams and tie-rods are made of pud

4. Isolation, characterisation and continuous culture of Lactobacillus spp. and its potential use for lactic acid production from whey
Abstract Bioprospecting of microorganisms with the potential of exploiting agro-industrial wastes is an active field of biotechnological research. In this study, we aimed to isolate a microorganism adapted to the dairy matrix with specific characteristics to produce lactic acid from dairy industry wastes, such as whey. Whey was collected from the agricultura

5. Screening and characterisation of gamma-aminobutyric acid (GABA) producing lactic acid bacteria isolated from Thai fermented fish (Plaa-som) in Nong Khai and its application in Thai fermented vegetables (Som-pak)
Abstract This study aimed to evaluate the capability of lactic acid bacteria (LAB) isolated from different kinds of fermented fish products (Plaa-som) on the production of γ-aminobutyric acid (GABA). Among them, isolate L10-11, identified as Lactobacillus plantarum, offered the highest GABA production and was selected for further study. The highest producti

6. Influence of sonication and in vitro evaluation of nifedipine self-nanoemulsifying drug delivery system
In order to develop a self-nanoemulsifying system, three components, olive oil, Tween 80, and Capmul, were used to construct a ternary phase diagram that helped to find the optimum formulation, which was loaded with nifedipine. The effect of sonication on drug loading was also evaluated. After that, measurement of the droplet size, size distribution, zeta po

9. Headspace analysis and characterisation of South African propolis volatile compounds using GCxGC–ToF–MS
ABSTRACT Propolis also known as "bee glue or bee resin" is a resinous mixture of bee saliva or bee wax and exudate from tree trunks and flowers, produced by honeybees. The composition of propolis varies depending on the vegetation the bees can access. It is therefore expected that propolis obtained from various localities may have different chemical profiles

10. Identification and Characterisation of Alternative Splice Variants of Hoxb9 and Their Correlation with Melanogenesis in the Black-Boned Chicken
ABSTRACT Homeobox B9 (HOXB9) gene has been demonstrated to be associated with melanogenesis in chicken plumage by high-throughput RNA sequencing. In this study, we cloned and characterised HOXB9 in black-boned chickens. Two alternative splice variants (HOXB9-1 and HOXB9-2) were identified in chicken feather bulbs. Expression analysis of HOXB9 in 11 differen

11. Genetic and biological characterisation of Zika virus isolates from different Brazilian regions
BACKGROUND Zika virus (ZIKV) infections reported in recent epidemics have been linked to clinical complications that had never been associated with ZIKV before. Adaptive mutations could have contributed to the successful emergence of ZIKV as a global health threat to a nonimmune population. However, the causal relationships between the ZIKV genetic determi

12. Fibrosis: a distinguishing feature in the pathology of neural leprosy
BACKGROUND Fibrosis in the peripheral nerve is the end stage of leprous neuropathy and the cause of the resulting permanent neural function impairments. Preventive measures to avoid this irreversible pathological state are a relief strategy for leprosy sufferers. OBJECTIVES The present study describes the frequency of fibrosis along with its characterisa
