Nutritional status being the first line of defense for host plants, determines their susceptibility or resistance against invading pathogens. In recent years, the applications of plant nutrient related products have been documented as one of the best performers and considered as alternatives or/and supplements in plant disease management compared to traditional chemicals. However, knowledge about application of plant nutrient related products for the management of destructive fungal pathogen Fusarium oxysporum f.

We hypothesized that (1) the accelerometer algorithm has similar accuracy in detecting behavioral estrus as does visual observation of pressure-sensitive sensors (estrus patches) in grazing beef cows; (2) variables measured by the accelerometer, such as estrus intensity, are associated with hormonal, ovarian, and uterine variables monitored before, during, and after estrus; and (3) the accelerometer variables are associated with the probability of pregnancy in grazing beef cows submitted to embryo transfer (ET). Fifty cows were fitted with accelerometer and patches to detect estrus after a synchronization protocol in eight subsequent rounds.

The release of these plastic microbeads into aquatic environments has raised significant concerns due to their direct availability for ingestion by organisms upon entering the recipient waters. In this study, twelve personal care products (PCPs; 5 face washes and 7 scrubs) were analyzed for microbead content, size, polymer type, and buoyant behavior.

The literature was systematically reviewed and data from 40 manuscripts including 78 experiments, and comprising 183 treatment means, were used for the analyses. The in-vitro parameters included rates of re-expansion, hatching, and survival of blastocysts either at 24 h or 72 h post-thawing/warming and total number (TN) of embryonic cells, whereas in-vivo parameters evaluated pregnancy rate between 35 and 60 d post embryo transfer (ET).

The fact that snakes feed on germ-infested rodents suggests that they encounter pathogenic microbes and likely possess antimicrobials. The venom is used only to paralyze the rodent, but the ability of snakes to counter potential infections in the gut due to disease-ridden rodents requires robust action of the immune system against a broad range of pathogens.

Antibacterial strategies to eradicate superbugs from hospitals/nursing homes have had limited success, suggesting the need for employing innovative preventative measures and better understanding of the prevalence of microbial pathogens in close proximity of susceptible populations. A total of 120 environmental samples were collected from the Aga Khan University hospital. Amoebae were identified using morphological characteristics as well as PCR using genus-specific primers, while bacteria were identified using standard biochemical testing.

In this paper, we establish the existence of travelling wave solution to an intrinsically non-linear differential-integral equation formed as a result of mathematical modelling of the evolution of an asexual population in a changing environment. This equation is first converted to a non-linear integral equation. The discretization and manipulation of the corresponding eigenvalue problem allows us to use the theory of positive matrices to get some very useful estimates and then to confirm the existence of solution.
