<p>Olive mill wastewater (OMWW) contains many phenolic compounds that if discharged without proper treatment, may lead to substantial risks to human health and deterioration of the environment and aquatic systems. In this study, an attempt was made to produce activated carbon from Rice Husk (RH). The RH was chemically activated by calcium chloride and was utilized for the removal of phenol from the aqueous solution. The removal efficiency using the Activated Rice Husk (ARH) was investigate
Phenol is the 11th most toxic 126 chemical substance and causes cancer by accumulating in the food chain. Adsorption of phenol is an effective and also environmentally friendly method for its removal. In this study, phenol removal by using powdered activated carbon (PAC) was optimized and modeled for various isotherms at constant mixing rate (150 rpm) and sample volume (100 mL); adsorbent dose (0.01-2 g), contact time (1-180 min), and initial phenol concentration (50-1000 mg L-1). Moreover, adso
Abstract
Background
Cannabis edibles are an increasingly popular form of cannabis consumption. Oral consumption of cannabis has distinct physiological and behavioural effects than injection or inhalation. An animal model is needed to understand the pharmacokinetics and physiological effects of oral cannabis consumption in rodents as a model for human cannabis edible use.

Abstract
African catfish (
Clarias gariepinus
) is a promising food fish species with significant potential and growing mass of production in freshwater aquaculture. Male African catfish possess improved production characteristics over females, therefore the use of monosex populations could be advantageous for aquaculture production. However, our knowledge about the sex determination mechanism of this species is still limited
Based on a critical literature review, this paper reveals that online dating studies on heterosexual users’ motivations and mate preferences reproduce two gendered as well as heteronormative arguments. First, women use dating technologies for seeking love whereas men prefer them for arranging casual sex activities. Second, men are inclined to prioritize physical appearance while women tend to value status during mate selection or swiping in e-dating language. The article calls these beauty-statu
ABSTRACT
The increasing rate of anisogamy (fusion between eggs and sperm) against asexual thelytoky is necessarily halved under a 1:1 sex ratio because males lay no eggs. The present dominance of anisogamy despite this twofold cost of male production is the greatest enigma in evolutionary biology. Various benefits of sex are insufficient to overcome this cost. How can anisogamy be maintained? Here, we propose hypotheses that anisogamy evolved as a female-male mutualism in which f
Abstract
In this short chapter I want to discuss the role of sex ratios in choosiness. So far, we have mostly reviewed intrinsic reasons for male choosiness to be expressed such as male investment and female quality; however, sex ratios may also be important drivers of choosiness. Sex ratios are important in population biology and influence the evolution and structure of mating systems. Most important for the purpose of this book is that they can change quickly in time and space.
The growing application of 3D concrete printing (3DCP) in construction has raised important questions regarding its long-term durability under freeze–thaw (F–T) exposure, particularly in cold climates. This review paper presents a comprehensive examination of recent research focused on the F–T performance of 3D-printed concrete (3DPC). Key material and process parameters influencing durability, such as print orientation, admixtures, and layer bonding, are critically evaluated. Experimental findi

Roller compacted concrete (RCC) is a durable, economical, low-maintenance material for low speed heavy duty paving applications. However, it is difficult to prepare laboratory specimens to represent field performance, because RCC is very dry and requires considerable compactive effort to achieve field densities. The gyratory compactor, commonly used to prepare hot mix asphalt specimens, may be used in preparing specimens for laboratory testing. Materials and mix designs from two industrial pavin
Although foamed concrete was practically created about 100 years ago, there are no current standards for foamed concrete and test methods for determining its properties. Hence, while the assessment of mechanical properties can be found in the literature, the assessment of the durability of foamed concrete is rare and is most often carried out due to a specific impact or for a specific composition of foamed concrete. Therefore, this work presents the results of tests on foamed concrete with densi
In order to improve the accuracy of the analysis of the impact of freeze–thaw cycle on concrete durability in a salt freezing environment, the numerical simulation of the impact of the freeze–thaw cycle on concrete durability in a salt freezing erosion environment is studied in this paper. Firstly, considering the influence of axial force and bending moment on the relationship between bending moment and curvature, a concrete fiber beam column model is established. Then, according to the joint in
