Harmful rays coming from the sun cause negative effects on human body. Sunscreens and UV protective products are used to reduce prevent these effects. Plants have been in medicine cosmetics for centuries, potential treat skin diseases. Consumers tend use sunscreens that contain natural ingredients instead of synthetic sunscreens. In this study, vitro solar protection factor (SPF) values water e...

A graph G is a fractional ( , b k )-critical covered if − U [ ]-covered for every ⊆ V ) with | = which first defined by (Zhou, Xu and Sun, Inf. Process. Lett. 152 (2019) 105838). Furthermore, they derived degree condition to be graph. In this paper, we gain an independence number connectivity verify that ≥ max {2 +1)( +1)+4 bk +5/4 ,( +1) 2

This study investigated the effect of dietary supplementation with calcium salts of fatty acids using 48 Afshari ewes randomly allocated to four treatments. All groups used in flushing period and only the source of energy were different between rations. The ewes were divided into four groups: A-barely grain; group B-received 5% of CSFA with source of flaxseed oil (w3); group C-received 5% of CS...

We are interested in the relation between the pathwidth of a biconnected outerplanar graph and the pathwidth of its (geometric) dual. Bodlaender and Fomin [2], after having proved that the pathwidth of every biconnected outerplanar graph is always at most twice the pathwidth of its (geometric) dual plus two, conjectured that there exists a constant c such that the pathwidth of every biconnected...

Tisserand graphs are a widespread tool for interplanetary trajectory and Moon tour design. They based on the Jacobi constant being an integral of motion in Circular Restricted Three Body Problem (CR3BP); as such, classical graph does not include perturbation bodies other than flyby bodies. Low-energy transfers Earth-Moon system make use combined Earth, Moon, Sun gravities, exploiting third body...

Zero forcing is a dynamic graph coloring process whereby a colored vertex with a single uncolored neighbor forces that neighbor to be colored. This forcing process has been used to approximate certain linear algebraic parameters, as well as to model the spread of diseases and information in social networks. In this paper, we introduce and study the connected forcing process – a restriction of z...
