The literature on tobacco has traditionally focused health effects, public policies for control, and smoker profiles. However, there is a notable gap in understanding the supply chains industry practices within market. This paper addresses this by examining structure of market Lebanon. Using an exploratory qualitative research approach, maps chain Lebanon investigates interactions among various stakeholders, including key policymakers, regulators, researchers, experts, as well their...
Growth and nitrogen status were assessed in pure mixed plantings of black cottonwood red alder. Annual dry-matter production 2-yr-old coppice (stump sprouting) the plots was higher than cultures Twigs from contained 18% more twigs plots. Soil collected cottonwood-alder alder contained, respectively, 9% 23% soil planting. For upper 15 cm mineral soil, average annual accretion under stand estimated at 32 kg/ha alder, 80 kg/ha. The beneficial effects stands, obtained such a short time, may have...
Tissue digestibility, essential oils, and levels of several chemical constituents were compared in foliage Douglas-fir. Genotypes with different susceptibilities to deer browsing used, was collected during the dormant season. In general, clones resistant had lower dry-matter cellulose digestibilities, oils greater inhibitory action on rumen microbial activity, higher content fats, total phenols, flavanols, leucoanthocyanins, chlorogenic acid. Results suggest that these resistance...
Important site and tree characteristics of western red cedar (Thujaplicata Donn ex D. Don) were examined in 19 natural stands the coastal interior zones Washington Oregon, U.S.A., Vancouver Island, British Columbia, Canada. The occurred at various elevations on different soil types differed age, pH, associated plant species. Current-year foliage was collected during winter concentrations N, P, K, S, Ca, Mg, Fe, Mn, B, Zn, Cu, Mo, Al, chlorophylls determined. Mean terminal growth previous 3...
This study aimed to shed light on the use of mealworm (Tenebrio molitor) frass (TMF) in rabbit diets and its effects growth performance, blood profiles, meat quality, fatty acid profiles. A total 48 Gabali rabbits were divided equally randomly into four groups be fed one dietary treatments: a control (T0) group three TMF groups, which included meal at 1 (T1), 2 (T2), 3 (T3) %, respectively. The isonitrogenous isoenergetic for 11 weeks, performance data recorded. Six per slaughtered end 11th...
An extensive rhizome system is an important aspect of the morphology and architecture salmonberry (Rubusspectabilis Pursh) its potential for regrowth following disturbance. Seasonal activity was studied by collecting segments monthly from February through October 1988 1989 four sites. Total nonstructural carbohydrate content determined were incubated in a growth chamber to determine periodicity shoot root production. The number dry weight shoots peaked March, declined April June when...
The animal gastrointestinal tract contains a complex microbiome whose composition ultimately reflects the co-evolution of microorganisms with their host and host’s environment. This study aimed to gain insights into adaptation microbiota local Egyptian cattle three different ecosystems (Upper Egypt, Middle Lower Egypt) distributed across 11 governorates (with an average 12 animals per governorate) using amplicon sequencing. We analyzed from 136 fecal samples through 16S rRNA gene sequencing...
Six plant species of known preference by black-tailed deer (Odocoileus hemionus columbianus) were used to evaluate several factors thought influence preference. Factors studied included chemical composition, in vitro fermentation dry matter and cellulose, effects essential oils water methanol extracts on rumen microbial activity vitro. Chemical analyses revealed considerable differences among all constituents; but, with the exception moisture which was generally higher more preferred...
Abstract To identify the genetic determinants of domestication and productivity Asian water buffaloes ( Bubalus bubalis ), 470 genomes domesticated river swamp along with their putative ancestors, wild arnee ) are sequenced integrated. The inherit morphology buffaloes. In contrast, most unique in morphology, but cluster levels genomic diversity Italian Indonesian decrease at opposite extremes distribution range. Purifying selection prevented accumulation harmful loss‐of‐function variants...
We examined the relationships between biomass or growth rates and leaf characteristics of 2-year-old trees two clones Populus. Leaf were total plant area weight, mean size (or weight) fully expanded terminal leaves, foliar concentrations contents N, P, K, Ca, Mg, chlorophyll, available carbohydrates. Sample (n = 156) chosen from irrigation regimes several fertilization treatments to provide a wide range environmental conditions for each clone. Total weight was strongly correlated with...
