From scraps to purification: innovative use of food waste-derived hydrochar in eradicating pharmaceutical pollutants.

Chemical products (CPs) such as carbamazepine and naproxen, present in aquatic environments, pose significant risks to both aquatic life and human health. This study investigated the use of hydrothermally carbonized food waste-derived hydrochar (AC-HTC) at three distinct temperatures (200, 250, and 300 °C) as an adsorbent to remove these CPs from water. Our research focused on the impact of hydrothermal carbonization temperature on hydrochar properties and the effects of chemical activation with phosphoric acid on adsorption capacity.

Static anti-windup compensator design for locally Lipschitz systems under input and output delays.

This paper proposes a static anti-windup compensator (AWC) design methodology for the locally Lipschitz nonlinear systems, containing time-varying interval delays in input and output of the system in the presence of actuator saturation. Static AWC design is proposed for the systems by considering a delay-range-dependent methodology to consider less conservative delay bounds. The approach has been developed by utilizing an improved Lyapunov-Krasovskii functional, locally Lipschitz nonlinearity property, delay-interval, delay derivative upper bound, local sector condition, L2 gain reduction from exogenous input to exogenous output, improved Wirtinger inequality, additive time-varying delays, and convex optimization algorithms to obtain convex conditions for AWC gain calculations.

Prevalence and Pattern of Dermatological Manifestations Among Substance Users Across Kashmir Valley in North India.

Background: Substance use has turned out to be one of the growing social problems of the present society cutting across all sorts of boundaries of the world with Kashmir Valley being no exception to this growing pathological phenomenon.

Aims And Objectives: To find the prevalence and pattern of dermatological manifestations among substance users across Kashmir Valley.

Materials And Methods: Cross-sectional study where patients of all age-groups, irrespective of gender, were enrolled in the three largest districts of Kashmir Valley over a span of 18 months.

Assessment, reliability, and validity of trichoscopy in the evaluation of alopecia in women.

Background: Alopecia in women is generally difficult to diagnose clinically. Trichoscopy may help make the correct diagnosis in doubtful cases.

Objective: The aims of the study were to assess the trichoscopic features of different types of alopecia in women, the reliability of trichoscopy vis-à-vis clinical findings, and the validity of trichoscopy in cases with a doubtful clinical diagnosis.

How Long Has It Been? Self-Construal and Subjective Time Perception.

Do people with independent and interdependent self-construals perceive the amount of time that has passed differently? Results from four experiments (one preregistered) and three supplementary ones reveal that an independent (vs. interdependent) self-construal elongates time perception by making individuals feel that more time has passed than in reality. We find evidence that this is likely because an independent self-construal increases arousal that affects one's "internal clock," which determines the subjective passage of time.

Privacy concerns can explain unwillingness to download and use contact tracing apps when COVID-19 concerns are high.

Governments around the world have increasingly relied on technology to promote public health, such as using electronic health records and portable fitness devices. During the COVID-19 pandemic, "contact tracing apps" for smartphones have also been promoted in many countries as a way to allow public officials to facilitate contact tracing. But uptake in virtually all countries where such apps have been promoted is slow, one reason being privacy concerns.

Female Pattern Hair Loss-An Update.

Female pattern hair loss (FPHL) is nonscarring progressive thinning of hair with gradual decrease in the number of hair, especially in the frontal, central, and parietal scalp, due to a process known as follicular miniaturization. The etiopathogenesis of FPHL is complex with multiple factors such as genetics, inflammation, hormones, and environment playing role in it. It usually manifests as slowly progressive hair thinning, mainly over the vertex and upper parietal scalp, the frontal hairline is often spared and the miniaturization is also not as severe as in men.

Valorisation of food waste via hydrothermal carbonisation and techno-economic feasibility assessment.

Food waste constitutes a remarkable portion of municipal solid waste. About one-third of the global food waste produced is lost with the food supply chain. Food waste in many countries is still dumped of in landfill or incinerated simultaneously with other municipal wastes.

Physicochemical, structural and combustion characterization of food waste hydrochar obtained by hydrothermal carbonization.

A solid carbon-rich product hydrochar, was prepared using hydrothermal carbonisation of food waste at temperatures of 200, 250 and 300 °C. To acquire detailed insight into physicochemical and structural properties, hydrochar samples were characterised using a range of techniques. The carbon content and higher heating value of food waste increased considerably from 39 to 73% and 15 to 31 MJ/kg corresponding to the heating temperature.

Caspase-1 recognizes extended cleavage sites in its natural substrates.

Objective: The preferred amino acids in the proteolytic sites have been considered to be similar between caspase-1 and caspase-9, which do not support their differential functions in inflammatory pyroptosis and apoptosis. We attempted to solve this problem.

Methods: We analyzed the flanking 20 amino acid residues in the cleavage sites in 34 caspase-1 and 11 capase-9 experimentally identified substrates.
