Use of a biopolymer for road pavement subgrade

This paper presents an extensive series of laboratory works and a prediction model on the design of a road pavement subgrade with Xanthan Gum (XG) biopolymer. The experimental works were carried out using mixtures of conventional aggregate for road pavement construction and XG at the ratios of 0%, 1%, 2%, and 5%, by dry weight. Unconfined compressive strength (UCS) and California bearing ratio (CBR) tests were conducted during the experimental works at the end of the various curing periods (4, 8, 16, and 32 days). An example of an improvement in the UCS values for a specimen with 5% XG addition tested at the end of 4-daycuring yields about a 200% increment by the end of a 32-daycuring. The CBR values of clean aggregates were found to be increased by about 300% by 5% XG addition for all curing periods applied. Furthermore, the energy absorption capacity of the aggregates was observed to be increased significantly by both XG inclusion and curing period. Moreover, scaled conjugate gradient (SCG) training algorithm-based models developed for the prediction of CBR and UCS test results displayed a very high estimation performance with the regression coefficients of R-2 = 0.967 and R-2 = 0.987, respectively. Evidently, XG biopolymer is provably of use as an alternative inclusion in road pavement subgrades constructed with conventional aggregates

Preliminary survey of nematodes associated with broadleaved trees in Izmit Forest Management Directorate, Turkey

A survey for Bursaphelenchus species was carried out in broadleaf forest sites of Izmit Forest Management Directorate. Nematodes were extracted from 128 wood samples, and 22 of them were cultured. Nematodes were identified using morphological characteristics and molecular analysis by amplifying D2-D3 LSU with primers. Only one Bursaphelenchus species, Bursaphelenchus mucronatus kolymensis, was isolated from Quercus petraea representing the first report from broadleaved tree species in Turkey. Paraphelenchus acontioides and Aphelenchoides heidelbergi were identified and presented herein as the first reports of these two species from Turkey. In addition, five Aphelenchoides species were also found and reported as Aphelenchoides sp.Duzce Universitesi [2016.02.02.447]Duzce Universitesi, Grant/Award Number: 2016.02.02.447WOS:0005819409000012-s2.0-8509291651

FRACTIONAL INTEGRAL ASSOCIATED WITH SCHRODINGER OPERATOR ON VANISHING GENERALIZED MORREY SPACES

WOS: 000445366500015Let L= -Delta + V be a Schrodinger operator, where the non-negative potential V belongs to the reverse Holder class RHn/2, let b belong to a new BMO theta(rho) space, and let I-beta(L) be the fractional integral operator associated with L. In this paper, we study the boundedness of the operator I-beta(L) and its commutators [b, I-beta(L)] with b is an element of BMO theta(rho) on generalized Morrey spaces associated with Schrodinger operator M-p,phi(alpha,V) and vanishing generalized Morrey spaces associated with Schrodinger operator VMp,phi alpha,V. We find the sufficient conditions on the pair (phi(1), phi(2)) which ensures the boundedness of the operator I-beta(L) from M-p,phi 1(alpha,V) to M-q,phi 2(alpha,V) and from VMp,phi 1 alpha,V to VMq,phi 2 alpha,V, 1/p - 1/q = beta/n. When b belongs to BMO theta(rho) and (phi(1), phi(2)) satisfies some conditions, we also show that the commutator operator [b, I-beta(L)] is bounded from M-p,phi 1(alpha,V) to M-q,phi 2(alpha,V) and from VMp,phi 1 alpha,V to VMq,phi 2 alpha,V, 1/p - 1/q = beta/n.Ahi Evran University Scientific Research ProjectAhi Evran University [FEF.A3.16.023]; Presidium of Azerbaijan National Academy of ScienceAzerbaijan National Academy of Sciences (ANAS)We thank the referee(s) for careful reading the paper and useful comments.

Effects of Ibuprofen on the physiology and outcome of rabbit endotoxic shock

Abstract Background Despite major developments in the management of septic shock, the mortality rate had progressively increased. Ibuprofen has been shown to have beneficial physiological effects when used as a treatment. However, there are conflicting results with respect to survival. This study aims to investigate the effect of ibuprofen on vital functions, various physiological parameters and survival during endotoxic shock in rabbits. Methods Twenty-eight New Zealand rabbits were randomly separated into four groups. The first group received only saline, the second was given 2 mg/kg intravenous endotoxin at t0, the third received 30 mg/kg ibuprofen 30 minutes after endotoxin administration, whilst the fourth group received ibuprofen 30 minutes before the endotoxin. Respiratory and heart rate, mean arterial blood pressure and rectal temperature were recorded. Complete blood counts were performed and thromboxane B2 was measured every 30 minutes for the first two hours, and then hourly over the course of the experiment. Urine samples were collected at the same time points for the measurement of prostaglandin E2. Results Ibuprofen was found to improve respiratory rate, heart rate, and arterial pressure. However, it did not improve the negative effects of endotoxin on body temperature, haematocrit values, white blood cell count, and thrombocyte number. Thromboxane B2 levels in group IV were significantly lower than in the other groups, and the increase started at a later timepoint. In ibuprofen-treated animals, Prostaglandin E2 levels stayed low for at least 90 minutes, but started to rise thereafter. While the average survival in Group II animals was 192.9 ± 46.9 minutes, those of groups III and IV were 339.1 ± 33.5 minutes (p Conclusions Ibuprofen appears to increase survival in endotoxic shock-induced animals. Therefore, it may be helpful for the prophylaxis and treatment of patients with, or who are likely to develop, septic shock.</p
