In this work, TiO2-doped carbon aerogel (TiO2/CA) was synthesized from sugarcane bagasse hydrothermal, freezedrying, and carbonization methods. The effects of the calcination temperatures of 400, 500, 600, 700, and 800 oC were also evaluated. The obtained TiO2/CA exhibits an ultralow density (0.021-0.032 g/cm3 ) and porosity of more than 97 %. The asprepared TiO2/CA was applied in photodegradation of methylene blue (MB) with the effects of dose sample and pH were also investigated.

Research on the impact of metabolic abnormalities on breast cancer prognosis is limited by small samples and assessment of laboratory values at a single time point, often prior to cancer diagnosis and treatment. In this population-based cohort, time-updated laboratory values were adjusted for cancer treatment to assess the association between metabolic risk factors (glucose, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglycerides) and breast cancer survival.

This paper reports effects of ultraviolet (UV) light radiation on the physicochemical, electrical and mechanical properties of low-density polyethylene (LDPE) cable insulating materials. Changes in structural and morphological properties of UV-aged samples were characterized by various analytical methods such as attenuated total reflection Fourier transform infrared spectroscopy (ATRFTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM) and atomic force microscopy (AFM).

The study "A study on carbon nanotube titanium dioxide hybrids: experiment and calculation" report synthesis of TiO2/CNTs composite by simple grinding method and study improving their photocatalytic activity under visible light. The photocatalytic activities of samples were assessed by photodegradation of methylene blue (MB). We have investigated the geometry and electronic structure of small TiO2 clusters adsorbed on singlewall carbon nanotubes (SWCNTs) support using first-principles density functional calculations.

Earthworms are present in all types of soil. Changes in land use influence populations of earthworms. However, information on the dynamics of earthworm populations in northern Cameroon is not available. This paper highlights the research carried out on the abundance, biomass, and diversity of earthworm populations throughout four types of land use in northern Cameroon. Earthworms were sampled throughout the rainy season in three regions, across pastures, woody savannahs, grass savannahs, and fields, using formaldehyde and hand sorting.

A series of degradable films was prepared, and 2 formulas of polyethylene (PE) films with the highest degradable performance were experimentally determined. These films contained 3.43% and 0.44% stearate, and were denoted as PE-3 and PE-4, respectively. Their biodegradability was studied in a laboratory-controlled composting test using ordinary PE film (OPEF) as a control. Contrast composting experiments indicated that the biodegradability of untreated samples was very low, and that the biodegradation rates of PE films after natural aging were significantly higher.

The oil absorption capacity decreased with blending. Other functional properties such as Water absorption capacity, Bulk density, swelling index, loaf height, and loaf volume increased as blends ration increases. Sensory characteristic reflected a down turn progression as blending was increased. Increase in cashew nut flour led to increase in chemical and functional quality values of the bread samples hence cheap bio functional ingredient which could also alleviate hidden hunger in rural populations with supplies of macro and micro nutrients.

The appendicular skeletal muscle mass index (ASMI) is an important risk indicator for osteoporosis because of the anatomical proximity and metabolic connection between muscle and bone mass. The present study investigated the relationship between ASMI and the bone mineral density (BMD) categories of postmenopausal women. In this cross-sectional study with a probabilistic sample, sociodemographic, lifestyle, menopause time, anthropometric, and physical activity variables were collected.

The effect of washing stabilized and unstabilized blown extruded films of low-density polyethylene (LDPE) used for greenhouse coverings naturally weathered in a sub-Saharan facility at Ghardaïa (Algeria) for 19 and 6 months, respectively, was studied. A comparison between unwashed and daily washed samples was done. The changes in the films’ properties were followed at regular intervals using various characterization methods (physicochemical and mechanical).

Mesostructured cellular foam silica was functionalized by an amino group (MCF-NH2) using the postsynthesis grafting method and utilized as a recyclable catalyst for the Knoevenagel reaction to afford α, β-unsaturated compounds. The catalyst was systematically characterized by various analyses such as nitrogen adsorption, X-ray diffraction, Fourier transform infrared spectrophotometry, scanning electron microscopy, transmission electron microscopy, thermogravimetric analysis, and Hammett indicator method.

Scalable, highly stable supercapacitor electrodes were developed from the mixture of a tea factory waste based activated carbon (AC) and a low-cost electrochemical exfoliated graphene (EEG). The hybrid electrodes showed notably enhanced stability at high current densities. The AC sample was prepared by chemical method and exposed to a further heat treatment to enhance electrochemical performance. Graphene used in the preparation of hybrid electrodes was obtained by direct electrochemical exfoliation of graphite in an aqueous solution.

Tumor stroma interaction is known to take a crucial role in cancer growth and progression. In the present study, it was performed gene expression analysis of stroma samples with ovarian and breast cancer through an integrative analysis framework to identify common critical biomolecules at multiomics levels. Gene expression datasets were statistically analyzed to identify common differentially expressed genes (DEGs) by comparing tumor stroma and normal stroma samples.
