Detection of pesticide and their effects on silkworm, Bombyx mori L. (Lepidoptera: Bombycidae)
Journal of Basic and Applied ZoologyBackground Non-spinning of cocoon and mortality in silkworm due to pesticides exposure has become a threat for sericulture industry in India. The effect of pesticide on silkworm and Acetylcholinesterase, one of the main targets for insecticides, was ...

Propellants, Explosives, Pyrotechnics, EarlyView.This study presents an alternative method to manufacture polymer‐bonded explosives by partially curing an HTPB‐based molding powder prior to compaction. The study shows that the length of partial cure time before compaction directly influenced the geometric fidelity, homogeneity, compressive strength, density, and internal microstructure.

Purification and Properties of Polyvinyl Nitrate and Its Compatibility With Solid Oxidizers
Propellants, Explosives, Pyrotechnics, EarlyView.ABSTRACT Polyvinyl nitrate (PVN) is a nitrate‐ester energetic binder that can be produced directly from polyvinyl alcohol—a cheap commodity feedstock—thereby offering potential cost and supply‐chain advantages over binders based on nitrocellulose and other specialty polymers.

The Detection of RCS Worm Epidemics
, 2005 This paper discusses the problem of automatically detecting the existence of Random Constant Scanning (RCS) worm epidemics on the Internet by observing packet tra#c in a local network. The propagation of the RCS worm is modelled as a simple epidemic.

Precision Medical Sciences, EarlyView.This study aimed to clarify the relationship between prescription medication use with chronic diarrhea (CD) and chronic constipation (CC) in adults. Population data was extracted from the 2007–2008 and 2009–2010 National Health and Nutritional Examination Surveys (NHANES). Multivariable logistic regression was used to calculate odds ratios (ORs) and 95%

A Novel Reflectarray Antenna with Reduced RCS
, 2018 A novel frequency selective surface (FSS) configuration in the reflectarray antenna is proposed for reduction of radar cross section (RCS) level in this work. Double-layer FSS structure is located behind the reflectarray antenna as a ground.

Precision Medical Sciences, EarlyView.Our analysis reveals a clear dose–response relationship between acupuncture sessions and the reduction of hormone therapy‐induced hot flashes. A threshold of approximately 10 sessions establishes a robust quantitative benchmark for achieving clinically meaningful neuro‐autonomic modulation and symptom relief.

Urban Housing Markets and Sustainability Risk: Empirical Evidence From South African Cities
Sustainable Development, EarlyView.ABSTRACT Despite the global shift toward sustainability and rising expectations for socially and environmentally responsible housing, evidence from South Africa's urban markets remains limited and underexplored. This study examines how sustainability‐related vulnerabilities shape downside housing risk across 60 cities between 2002 and 2021.
