One kind of construction on sunflower with two petals*

A sunflower (or ∆-system) with k petals and a core Y is a collection of sets S1,⋯, Sk such that Si∩Sj=Y for all i≠j; the sets S1\Y,⋯, Sk\ Y, are petals. In this paper, we first give a sufficient condition for the existence of a sunflower with 2 petals. Let F={A,B,C} be a family of subsets of a set { a1,⋯,am , b1,⋯,bn , c1,⋯,cn } with  and A={a1,⋯,am}, B={ b1,⋯,bn } and C={ c1,⋯,cn } are...

Reflection on medicinal plants, especially antivirals and how to reconsider ethnobotany as an interesting way for health preservation

The medicinal plants, which are at the origin of the medical sciences, are gradually passing from the apothecary vials, from the handmade bags of the tradipraticians to the laboratories to provide countless new medicines synthesis models. Today, chemical drugs have replaced most herbal drugs in pharmacies. Empirical knowledge has been neglected as chemistry progressed. Yet 80% of the world’s population is still...

Closed form solution for the valuation of deferred tax assets

Deferred tax asset (DTA) is a tax/accounting concept that refers to an asset that may be used to reduce future tax liabilities of the holder. In the banking sector, it usually refers to situations where a bank has either overpaid taxes, paid taxes in advance or has carry-over of losses (the latter being the most common situation). In fact, accounting and tax losses may be used to shield future profits from taxation,...

Genetic relationship and the occurrence of multiple gene resistance to coffee berry disease (Colletotrichum kahawae, Waller & Bridge) within selected Coffea arabica varieties in Kenya

The Coffee Berry Disease (CBD) epidemics destroy up to 100% of the crop on a susceptible variety. Resistance to CBD is conferred by the T-gene in Hibrido De Timor  (HDT), R-gene in Rume Sudan (RS), and k-gene in K7, which were assembled in resistance varieties Ruiru 11(R11) and Batian. This study aimed to evaluate the genetic relationship between R11 and Batian with their parents' HDT, RS,  SL8 and confirm...
