Structure and Properties of Recycled Polyester-cotton Blended Fiber/HDPE Composite Board (2021)

Abstract Recycled polyester-cotton blended fiber/high density polyethylene (HDPE) composite boards were prepared by internal mixing and compression molding two-step process with maleic anhydride grafted ethylene polyethylene-octene elastomer (POE-g-MAH) as compatibilizer. Two kinds of recycled polyester-cotton blended fiber were used as reinforcing fibers, including polyester-cotton long fiber (F1) and polyester-cotton short fiber (F2). Microstructure and properties of the composi

A 10% Lactobionic acid‐containing moisturizer reduces skin surface pH without irritation—An in vivo/in vitro study (2019)

SummaryBackground/ObjectivesStratum corneum acidification is a newer strategy in management of inflammatory dermatoses; acidifying emollients are normally used for that purpose. However, a decrease in pH of the skin is commonly connected to an increase in irritation. The aim of this study was to investigate whether lactobionic acid (LA), cosmeceutical active and "superacid" belonging to the class of alpha‐hydroxy acids (AHAs), could decrease pH of skin surface without irritation.MethodsSafety pr

Optimal application method of a moisturizer on the basis of skin physiological functions (2022)

AbstractBackgroundClinical studies have clarified the usefulness of moisturizers for dry skin diseases. However, few reports exist on the appropriate application of moisturizers with respect to the skin physiological functions.AimsTo clarify the optimal moisturizer application method on the basis of skin physiological functions.MethodsThis study investigated the appropriate time, dose, and frequency of moisturizer application from the perspective of skin physiology. In healthy subjects, the stra

Understanding humectant behaviour through their water‐holding properties (2021)

AbstractObjectiveHumectants perform essential roles in the formulation of topical moisturizing products in terms of delivery of active ingredients, consumer experience and biophysical behaviour. How they retain and release water is key to understanding their behaviour.MethodsDynamic vapour sorption (DVS) was used to monitor the dehydration kinetics of three humectants widely used in topical formulations—glycerine, dexpanthenol and urea. Model aqueous solutions with concentrations of 20% w/w were

Hygrothermal Modelling of one-dimensional Wall Assemblies: inter-model Validation between WUFI and DELPHIN (2023)

Abstract Various Heat-Air-and-Moisture models may give divergent results for the same case, due to differences in assumptions, simplifications, or approximations. Inter-model comparisons have been used as ‘peer review’, but common limitations and/or mistakes may remain concealed. Recent validation efforts, confronting simulations with measured datasets, use limited materials, configurations, and boundary conditions. A thorough and stepwise assessment is still lacking. In this stud

Hygrothermal performance of the building envelope with low environmental impact: case of a hemp concrete envelope (2021)

Abstract This document is a case study of hemp-based materials integrated into the building envelope for African and North American’s applications. The objective is to evaluate the energy performance of hemp concrete for construction in Montreal, Canada, where heating predominates and in Dori, Burkina Faso, where air conditioning predominates. The effect of thermal and hygrothermal comfort of hemp concrete, glass wool, cement block and compressed earth brick walls were simulated t

Pain Testing in Endometriosis for the Clinician (2021)

Clinical pain testing has been used to ascertain the pathophysiology of many clinical conditions, but its use in the management of endometriosis has been limited. Although the testing can require the use of complex testing in the laboratory, this chapter is directed to look at a test for allodynia that can be applied in the clinic. The test for cutaneous allodynia is validated, does not require sophisticated tools, and is readily accepted by woman. The presence of allodynia in certain gynecologi

Effect of substitution ratio of wheat flour with coconut dregs and avocado seed flour as gluten-free flour on the chemical characteristics of white bread (2023)

Analysis of the chemical properties of white bread whose formulation is modified by substitution of coconut dregs flour and avocado seed is very important to do to find out how much increase in dietary fiber content in white bread and to determine the content contained in it, which can affect the quality of the white bread. The research aimed to study the effects of coconut dregs flour and avocado seed ratios on chemical properties and daily index sufficiency of white bread. This research used a
