Complexes of polyphosphate esters with antibiotics were developed in Lviv Polytechnic National University together scientists Institute Animal Biology NAAS to reduce the negative impact on animal body. The conducted experiments allow assessing effect antibiotics, and complexes body laboratory animals based biochemical markers hepato- nephrotoxicity. administered average daily therapeutic doses....

We show that the 4-coloring problem can be solved in polynomial time for graphs with no induced 5-cycle C5 and no induced 6-vertex path P6.

This paper strengthens the excluded-minor characterization of GF(4)-representable matroids. In particular, it is shown that there are only finitely many 3-connected matroids that are not GF(4)-representable and that have no U2, 6 -, U4, 6 -, P6 -, F & 7 -, or (F & 7 )*-minors. Explicitly, these matroids are all minors of S(5, 6, 12) with rank and corank at least 4, and P"8 , the matroid that ca...

A study was conducted at Kalamandari Tanda-1 micro-watershed, Karnataka, India, to assess the spatio-temporal variability of surface soil properties sampled from 23 varied soil-phase units, delineated using IRS P6 LISS-IV merged Cartosat-I imagery (2.5 m spatial resolution). Three sets samples (231 in each set) were collected, analyzed, and interpolated evaluate variability. Further soil-phase-...

We prove that there are 24 4-critical P6-free graphs, and give the complete list. We remark that, if H is connected and not a subgraph of P6, there are infinitely many 4-critical H-free graphs. Our result answers questions of Golovach et al. and Seymour.

Although we and others have generated IRS-2 knock-out (IRS-2(-/-)) mice, significant differences were seen between the two lines of IRS-2(-/-) mice in the severity of diabetes and alterations of beta-cell mass. It has been reported that although IRS-1 and IRS-3 knock-out mice showed normal blood glucose levels, IRS-1/IRS-3 double knock-out mice exhibited marked hyperglycemia. Thus, IRS-1 and IR...

On the basis of mouse I-Ab-binding motifs, two sequences of the murine apolipoprotein B-100 (mApoB-100), mApoB-1003501-3515 (designated P3) and mApoB-100978-992 (designated P6), were found to be immunogenic. In this report, we show that P6 is also atherogenic. Immunization of Apoe-/- mice fed a high-fat diet (HFD) with P6 resulted in enhanced development of aortic atheroma as compared to contro...

Soil Salinity has been a large problem in arid and semi arid regions. Preparation of such maps is useful for Natural resource managers. Old methods of preparing such maps require a lot of time and cost. Multi-spectral remotely sensed dates due to the broad vision and repeating of these imageries is suitable for provide saline soil maps. This investigation is conducted to provide saline soil map...

areas surrounding mines are severely vulnerable to pollution due to mine explorations, excavations and transportations. nowadays spectrophotometers and spectral reflectance are applied for estimating the concentration of pollutants due to high costs of sampling and laboratory measurements. this research was carried out to determine spatial distribution of lead concentration in soil particle siz...
