three different solvents namely; hexane, ethyl acetate and ethanol were used in partitioning the extracts obtained from piper guineense seeds and solvent extracts were investigated for the presence or absence of secondary metabolites. extracts were further evaluated on adult maize weevils, sitophilus zeamais. experiment was carried out under laboratory conditions at 27 ± 2 °c ambient temperatur...

the aim of this review was to represent a category of applied plant biostimulants and to highlight the effect of their application on morphological and phytochemical properties of medicinal plants in in vivo and in vitro conditions and their mechanism of action. plant biostimulants, safe for both human beings and the environment, are substances or materials, except for nutrients and pesticides,...

In [2] the notion of “uniformly ideal” was introduced and developed the basic theory. In this article we introduce and advance a theory which, in a sense, dual to that i.e, the notion of “uniformly secondary module”.

Introduction Use of hadron therapy as an advanced radiotherapy technique is increasing. In this method, secondary particles are produced through primary beam interactions with the beam-transport system and the patient’s body. In this study, Monte Carlo simulations were employed to determine the dose of produced secondary particles, particularly neutrons during treatment. Materials and Methods I...

Prostate cancer is the most common and second leading cause of death among men in the world. Nowadays, radiotherapy has been known as one of the most affecting methods for prostate cancer treatment. Nevertheless, radiotherapy is accompanied by the concern of developing secondary cancers by the scattered radiation to the neighbor  organs at risk.
