Let $ \{(A_{i},B_{i})\}_{i=1}^{m} be a set pair system. Füredi, Gyárfás, and Király called it 1 -cross intersecting if |A_{i}\cap B_{j}| is when i\neq j 0 i=j . They studied the systems their generalizations and, in particular, considered m(a,b,1) , maximum size of system which |A_{i}|\leq |B_{i}|\leq b for all i proved that m(n,n,1)\geq 5^{(n-1)/2} asked whether there are upper bounds on m(n,n...

A series of (5-nitrofuran-2-yl)-1, 3, 4-thiadiazole-2-yl derivatives 6a–6e have been synthesized and screened for in vitro anti-leishmanial activity against the promastigote form of L. major. The structure of Schiff bases were confirmed by 1H NMR, IR. Screening results indicate that all of the designed and synthesized final compounds (6a-6e) significantly reduced the viability of promastigotes ...

ABSTRACT- The influence of foliar application of urea, humic acid (HA), Zinc (Zn), and Boron (B) on potato yield (CV. Cror) was studied in a field experiment during 2010-2012 at the research farm of Nuclear Institute for Food and Agriculture (NIFA). Treatments consisted of i) Control, ii) Nitrogen-Phosphorous-potassium (NPK) (250,150,250 kg ha-1) , iii) NPK (125,75,125 kg ha-1) with 0.03% HA, i...

This research focuses on the characteristics of polyvinyl alcohol and starch polymer blends doping with Rhodamine-B. The were prepared using solution cast method, which comprises 1:1(wt. /wt.). PVA had different ratios glycerin 0, 25, 30, 35, 40 % wt. ratio 30% wt was found to be most suitable mechanical properties by strength elasticity. blend 1:1 starch/PVA doped Rhoda mine-B dye 1, 2, 3, 4, ...

In this work, the some collective properties of even-even Ti isotopes in A50 mass region were studied by using interacting boson model-1 (IBM-1). This study includes calculations energy levels and electromagnetic transition rates 44-48Ti 52-60Ti isotopes. The neutron number 50Ti isotope is 28, magic number, was excluded from IBM-1 calculations. First, ratios analyzed comparing typical values U...

while w(d) = 4=15 and we conclude that, in any event, w(B 3) 1. Case 3. Suppose jB 3 j = 4. B 3 cannot contain an X 1 item, since 1=2 + 3(1=5) > 1. Neither can it contain two X 2 items, since 2(1=3) + 2(1=5) > 1. Similarly, it cannot contain four X 3 items, since each has size greater than 1/4. However, if it contains three items of type X 3 and one of type X 4 , then w(B 3) 3(4=15) + 1=5 = 1. ...
