This test method provides a means for determination of the impedance permeability of ferromagnetic materials under the condition of sinusoidal current (sinusoidal H) excitation. Test specimens in the form of laminated toroidal cores, tape-wound toroidal cores, and link-type laminated cores having uniform cross sections and closed flux paths (no air gaps) are used. The method is intended as a means for determining the magnetic performance of ferromagnetic strip having a thickness less than or equal to 0.025 in. [0.635 mm].

This test method provides dc hysteresigraph procedures (B-H loop methods) for the determination of basic magnetic properties of materials in the form of ring, spirally wound toroidal, link, double-lapped Epstein cores, or other standard shapes that may be cut, stamped, machined, or ground from cast, compacted, sintered, forged, or rolled materials. It includes tests for normal induction and hysteresis loop determination taken under conditions of continuous sweep magnetization. Rate of sweep may be varied, either manually or automatically at different portions of the curves during measurement.

Extranodal extension (ENE) is an adverse prognostic factor for oral squamous cell carcinoma (OSCC), and patients with OSCC along with ENE require neck dissection. In this study, we developed a novel ENE histologybased pathological predictor using MMP14 expression patterns in small biopsy specimens.

The freshwater shrimp species Caridina cucphuongensis (family Atyidae) was poorly described by Dang (1980). Moreover, the taxonomic status of this species is hard to verify as the types have been lost. This study provides a redescription of the species and designation of a neotype specimen.

Mechanistic study of hot cracking and development of new resistant Ni-based high-Cr alloy weld metal
The authors studied a novel thermal cycling test under tensile loading of the round-notched bar type specimen, using Gleeble test machine. In this kind of testing the mechanism of the DDC is thought to be different from the earlier observations and hypotheses.

A small rhacophorid, Philautus petilus known from only the female holotype, is recorded for the first time outside of the type locality in Laos. Three specimens, containing the first known males of the species, were collected from Muong Nhe Nature Reserve in Dien Bien Province, northwestern Vietnam. The Vietnamese specimens are identified as P. petilus based on morphological similarities with the holotype from Laos. In addition, our molecular data verify the transfer of this species from Philautus to the genus Theloderma.

Coxiella burnetii is the etiological agent of Q fever, a zoonosis affecting many animal species including sheep and goats. The aims of this study were to evaluate the shedding of Coxiella burnetii in small ruminant herds and to identify the pathogen’s genotypes and sequence types (STs) using multiple-locus variable number tandem repeat analysis (MLVA) and multispacer sequence typing (MST) methods.

Between 2018 and 2020, 989 clinical specimens from pigs showing clinical signs of a variety of swine diseases in 27 provinces in China were sampled and submitted for further testing. Nested PCR targeting the 16S rRNA gene of Mycoplasma hyopneumoniae and subsequent sequencing were used to analyse these specimens. Mycoplasma hyopneumoniae-positive samples were assayed by multilocus sequence typing (MLST).

For more than a century, pearly tree frog from its type locality (East Indies; Java; Mt. Wilis) are undiscovered. Current studies about the distribution of Nyctixalus margaritifer are reported as known only from West Java and Central Java. In this paper, we collected one individual of pearly tree frog, N. margaritifer in the Western part of Mt. Wilis, which belongs to Gunung Sigogor Nature Reserve, Ponorogo, East Java. This is the third specimen, which is discovered from the Mt. Wilis after the lost holotype in 1882 and the neotype in 1885.

Gene expression variation is a key underlying factor influencing phenotypic variation, and can occur via cis- or trans-regulation. To understand the role of cis- and trans-regulatory variation on population divergence in chicken, we developed reciprocal crosses of two chicken breeds, White Leghorn and Cornish Game, which exhibit major differences in body size and reproductive traits, and used them to determine the degree of cis versus trans variation in the brain, liver, and muscle tissue of male and female 1-day-old specimens.

Polymer quenchants based on polyalkylene glycols (PAG) are currently the most widely used type of aqueous quenchants. In this paper, the numerical simulation method by Sysweld software was used to predict the distortions of C-ring model using 100Cr6 steel when quenched in the difference media. The simulation results are in good agreement with the experimental values, and they also showed that the top of C-ring was opened after deformation.
