by Edgar O. Aviles-Rosa, Andrea C. Medrano, Ariela Cantu, Paola A. Prada-Tiedemann, Michele N. Maughan, Jenna D. Gadberry, Robin R. Greubel, Nathaniel J. Hall Working Dogs have shown an extraordinary ability to utilize olfaction for victim recovery efforts. Although instrumental analysis has chemically characterized odor volatiles from various human biospecimens, it remains unclear what perceptually constitutes human scent (HS) for dogs. This may be in part due to the lack of methodology and equipment to train and evaluate HS perception. The aims of this research were 1) to develop an automate ..read more

by Hongwei Li, Xiaohang Wang, Michael Vinsky, Ghader Manafiazar, Carolyn Fitzsimmons, Liang Li, Changxi Li Reducing enteric methane (one greenhouse gas) emissions from beef cattle not only can be beneficial in reducing global warming, but also improve efficiency of nutrient utilization in the production system. However, direct measurement of enteric methane emissions on individual cattle is difficult and expensive. The objective of this study was to detect plasma metabolites that are associated with enteric methane emissions in beef cattle. Average enteric methane emissions (CH4) per day (AVG_ ..read more

by Waleed Khan, Nasru Minallah, Madiha Sher, Mahmood Ali khan, Atiq ur Rehman, Tareq Al-Ansari, Amine Bermak Agricultural Remote Sensing has the potential to enhance agricultural monitoring in smallholder economies to mitigate losses. However, its widespread adoption faces challenges, such as diminishing farm sizes, lack of reliable data-sets and high cost related to commercial satellite imagery. This research focuses on opportunities, practices and novel approaches for effective utilization of remote sensing in agriculture applications for smallholder economies. The work entails insights from ..read more

Shepherd, Brynn H. Voy, Phillip R. Myer To improve animal performance and modify growth by increasing lean tissue accretion, beef cattle production has relied on use of growth promoting technologies such as beta-adrenergic agonists. These synthetic catecholamines, combined with the variable inclusion of rumen degradable (RDP) and undegradable protein (RUP), improve feed efficiency and rate of gain in fini ..read more

by Ahmed M. El-Feky, Mohamed Saber, Mahmoud M. Abd-el-Kader, Sameh A. Kantoush, Tetsuya Sumi, Faisal Alfaisal, Amal Abdelhaleem The presence of a wastewater treatment plant in the Arab El-Madabegh region, which discharges excessive amounts of raw effluent toward the nearby farming fields, is the area’s main issue. Examining the harmful implications of raw effluent releases on groundwater quality, determining if treated wastewater effluent complies with regulations for discharge into the aquatic environment, and assessing irrigation appropriateness by the effluent are the main goals of this wor ..read more

by Monica Marra, Paolo Mussano, Eugenio Pinton, Cinzia Montemurro, Elena Baldoni, Claudio Ratti, Slavica Matić, Chiara D’Errico, Gian Paolo Accotto To accurately determine the spread of any pathogen, including plant viruses, a quick, sensitive, cost-effective, point-of-care diagnostic assay is necessary. Wheat spindle streak mosaic virus (WSSMV) is a Bymovirus, transmitted by the plasmodiophorid Polymyxa graminis Led, which causes yellow mosaic and reduces the grain yield in wheat. Currently, detection protocols for WSSMV use ELISA or more sensitive PCR-based approaches requiring specialized l ..read more

by Shengchen Zhao, Dapeng Wang, Yunhui Li, Wei Wang, Jihong Wang, Haibo Chang, Jingmin Yang Saline-alkali soil significantly impairs crop growth. This research employs the impacts of the modifier and water-soluble fertilizer, as well as their interaction, on the root systems of alfalfa and leymus chinensis in saline-alkali soil. The results exhibit that the hydrochar source modifier effectively enhances the root growth of both forage species. There are certain improvements in the root growth indicators of both crops at a dosage of 20 g/kg. Root enzyme activity and rhizosphere soil enzyme activ ..read more

by Carlos Alberto Tosta Machado, Katharine Valéria Saraiva Hodel, Herman Augusto Lepikson, Bruna Aparecida Souza Machado Essential oil (EO) distillation units, which are commonly installed on farms, have difficultly accessing knowledge centers. The apparent simplicity of the process hides unwanted losses and deviations that go undetected and, therefore, not corrected. This article proposes improvements to the process that are based on “4.0” technologies in order to detect and correct two important deficiencies, with an impact on the yield, quality and environmental performance. The first defic ..read more
