QRsens represents a family of Quick Response (QR) sensing codes for in-situ air analysis with customized smartphone application to simultaneously read the QR code and colorimetric sensors. Five sensors (temperature, relative humidity (RH), three gas (CO 2 , NH 3 H S)) were designed aim proposing two end-use applications ambient analysis, i.e., enclosed spaces monitoring, smart packaging. Both i...

Intensification of dryland cropping systems with cover crops (CCs) in the semi-arid central Great Plains could enhance soil health and diversify production when used for forage. This study was conducted from 2015 to 2020 determine forage mass, nutritive value CCs, effects dual-purpose CCs on properties a no-till winter wheat (Triticum aestivum L.)–grain sorghum [Sorghum bicolor (L.) Moench]–fal...

Knowledge of genetic parameters is essential for improved reproductive management and increased yield. Quantitative analysis of genetic parameters is lacking for many breeds of buffaloes. This article provides the first estimate of genetic parameters for dual purpose (meat and milk) Brazilian Jaffarabadi buffaloes, using Bayesian inference. Data on milk yield (MY), lactation length (LL), weight...

Hemp is a broad term used to describe the many varieties of Cannabis sativa L. that produce less than 0.3% tetrahydrocannabinol (THC). The crop globally significant, but only recently was allowed be grown again in United States. There are uses for industrial hemp, which include oil, seed, and fiber, market hemp rapidly growing as more states legalizing its production. expected grow from $5.33 b...

This simulation study was to evaluate low cost feeding strategies in response to higher cost of commercial concentrates to maintain current milk sales from dual purpose cattle herds in the humid lowlands of western Venezuela. Data were from farm surveys in 1987 and 1988. Baseline net margins from milk and beef per cow per year were $132 and $99 for two farm cases with average dally milk of 10 a...

Ever since Darwin (1871), most work on sexual selection has included a distinction between male– male competition and female choice. Male–male competition favors not only traits such as overt weapons used to fight other males (Darwin 1871; Andersson 1994) but also less overt traits such as enhanced locomotor or sensory capability favored in scramble competitions (Able 1999; Bertin & Cézilly 200...
