Abstract:

Some dermatoglyphic components that can be used to analyze a population are fingerprint patterns and Axial Tri-Radius Digital (ATD) angles because they are unique to each ethnic group. This study aimed to determine variations in fingerprint patterns and ATD angles in the Komering population in Palembang. The study of fingerprint patterns and ATD angles was descriptive. The sample size was 43 respondents registered in the Gunung Batu Family Association (IKA GUBA) Komering Ulu Timur in Palembang City. The results showed that the ulnar loop pattern was the most common fingerprint pattern, with 90

But what about the idea of a turn (a rotation around a fixed point) or of the space between two rays, and what exactly is a degree?

Abstract:

Whenever satisfied anglers are an important objective of recreational fisheries management, understanding how trip outcomes influence satisfaction reports is critical. While anglers, generally, prefer high catch rates and large fish, the relative importance of these catch outcomes for catch satisfaction has not been established across species and angler types. We examined relationships between angler specialization, trip outcomes (both catch and non-catch characteristics such as crowding), and catch satisfaction across six freshwater fish species in northern Germany. As expected, catch satisfa

Abstract:

An angled single-excitation elliptical vibration system for ultrasonic-assisted machining was developed in this paper, which was composed of a giant magnetostrictive transducer and an angled horn. Based on the continuous boundary conditions between the components, the frequency equation of the angled vibration system was derived, and the resonant frequencies of vibration systems with different angles were theoretically calculated. The finite element method was employed to investigate the impact of varying angles on the resonant frequency, elliptical trajectory, phase difference, and output amp

Abstract:

The use of fiber-reinforced polymer (FRP) composite materials are continuously growing in civil infrastructure due to their high strength, low weight, and manufacturing flexibility. However, FRP is characterized by sudden failure and lacks ductility. When used in construction, gradual failure of FRP components is desired to avoid catastrophic structural collapse. Due to its mechanical orthotropy, the behavior of FRP relies significantly on fiber orientation and stacking sequence. In this paper, a novel multi-angled glass fiber reinforced polymer (GFRP) composite laminate showing pseudo ductile

This study utilized data extracted from the 2013 National Saltwater Angler Survey to understand saltwater recreational anglers’ preferences toward recreational fisheries management strategies, to identify groups exhibiting common patterns of responses, and to examine the association between socio-demographic characteristics and the groups identified. Saltwater recreational anglers’ preferences toward recreational fisheries management strategies were examined through factor analysis which identified four reliable factors.

Abstract:

Solutions for finding the natural electric potential from polarized oblique-angled (4-sided with complete asymmetry) and polyhedral electron-conducting bodies found in nature are performed. An oblique body is a layer with different angles of inclination of its upper edge and side faces, i.e. a body that has complete asymmetry. A theoretical search of various combinations of the angles of inclination of the faces and the lengths of these faces allows you to select an anomaly of the electric potential for tetrahedral bodies of any complexity. A polyhedral body is an 8-sided one that approximates

Abstract An experimental study of supersonic flow over wall mounted cavities with different aft wall angles is carried out. Unsteady pressure measurements were made on the walls and floor of the cavity. Data analysis was performed on the experimental results using statistical methods. In the case of higher angled cavities, the presence of an upstream traveling acoustic wave could be confirmed. For lower angled cavities (60 degrees and less) where the acoustic wave could not be identified, the flow inside the cavity was more or less stable. Mode switching occurring in higher angled cavities was

In Southern California, white croaker caught within proximity to the Palos Verdes Shelf Superfund Site have been found to be contaminated with such high levels of dichloro-diphenyl-trichloroethane and polychlorinated biphenyls that fish consumption advisories recommend that this fish should not be consumed. In response to this risk, the U.S. Environmental Protection Agency has initiated an Angler Outreach Program designed to reduce the quantity of contaminated fish (specifically, white croaker) anglers bring back to the community.

Abstract:

Mechanisms resulting in hyperstability (where catch per unit effort (CPUE) remains high as fish density declines) in recreational fisheries are poorly understood owing to a lack of experimental data. We collected data on angler CPUE and fish density to determine whether hyperstability exists in the rainbow trout (Onchorhynchus mykiss) lake fishery of British Columbia. We contrasted the relationship between CPUE and fish density in an open-access recreational fishery with an experimental fishery (a set of lakes that had restricted access, standardized fishing methods, and no heterogeneity in an

Abstract:

Abstract The aim of the study was to compare the catch efficiency of novice and experienced anglers float fishing with different hook types. The mortality of fish that were caught and released was determined based on the experience of the angler and the type of hook used. The mean catch rates of the experienced angler was 46.7 fish per hour, while that of the novice angler was 33.7 fish per hour. The landing efficiency of fish using hooks with micro-barbs was higher than that with barbless hooks. Angling experience had a significant impact on the mean time required to unhook caught fish and al
