Scavenging of human remains by dogs can make the process of identification and analysis of perimortem trauma difficult. Numerous scientific studies have been published about the damage caused to osseous remains by dogs due to postmortem consumption orlethal attacks. However, few studies deal with the issue of the analysis of clothing associated with human remains. The purpose of this investigation was to identify patterns of damage caused by domestic dogs to commonly used, woven textiles. Forty-five cloth bags were used (20 × 30 cm each), made by hand with three different types of woven textile (15 of each textile): stretch(polyester with elastic), denim, and polyester, with a thickness of 40.84, 57.95, and 31.46 threads per cm², respectively. The canine sample consisted of 15 dogs, differing in size, age, and sex, coming from the “Fundación Chile Mestizo,” in Santiago, Chile. Through analysis of variance, researchers examined the relationship between the type of textile and presence of damage, and later, they calculated the frequency of damage according to type of textile. The statistical program Minitab 19 was used to do this. According to the results, four types of patterns were identified: puncture and mastication, present in 62% and 75% of the cases, respectively; perforation; and “hole and tear” damage in 91% of the analyzed cases. Regarding the relationship between textile type and frequency of damage, researchers found that the thickness and weight of the textile are directly connected to the type of damage.

Interspecies somatic cell nuclear transfer (iSCNT) is an emerging assisted reproductive technology (ART) for preserving Nature’s diversity. The scarcity of oocytes from some species makes utilisation of readily available oocytes inevitable. In the present study, we describe the successful cloning of coyotes (Canis latrans) through iSCNT using oocytes from domestic dogs (Canis lupus familiaris or dingo). Transfer of 320 interspecies-reconstructed embryos into 22 domestic dog recipients resulted in six pregnancies, from which eight viable offspring were delivered. Fusion rate and cloning efficiency during iSCNT cloning of coyotes were not significantly different from those observed during intraspecies cloning of domestic dogs. Using neonatal fibroblasts as donor cells significantly improved the cloning efficiency compared with cloning using adult fibroblast donor cells (P < 0.05). The use of domestic dog oocytes in the cloning of coyotes in the present study holds promise for cloning other endangered species in the Canidae family using similar techniques. However, there are still limitations of the iSCNT technology, as demonstrated by births of morphologically abnormal coyotes and the clones’ inheritance of maternal domestic dog mitochondrial DNA.

The Relationship

The study discussed in this article was aimed to investigate the usages of e-resources, the relationship of access points with devices for accessing e-resources and influence of the use of e-resources on academic efficiency of faculty and technical staff of India’s first Agricultural University—Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, India. The study also showed usage levels of different types of e-resources amongst users if access points are correlated with devices employed and the effect of e-resources on academic efficiency of academics. A questionnaire was used as a data collection instrument. The use of e-resources was studied using a method to scaling responses, following Likert Scales. Data obtained were converted into scores using scale rating. Standard statistical techniques were used for the analysis of variance, correlation coefficients, and others. Originality/value. This study will help understand the extent to which different e-resources can be used, the relationship between access points and devices used, and the influence of e-resources on academic efficiency. The librarians engaged in agricultural universities can also utilize findings of the study for carrying out acquisition and management of e-resources.
