Abstract: Aim: Cases of child abuse and neglect (CAN) should be ideally managed by a multidisciplinary team. In the present study, our aim was to review the demographic and clinical features of cases of child abuse and neglect followed-up by the Child Protection Team of Ege University, Izmir, Turkey.Material and Method: The data of the cases of CAN referred to the multidisciplinary team of Ege University between August 2009 and 2010 were retrospectively reviewed. The demographic and clinical characteristics of the cases were summarized.Results: There were a total of 89 CAN cases evaluated by the team in our hospital during the last 12 months. The age of the cases ranged from 1 to 17 years, and 43 (48.3%) of them were male, while 46 (51.7%) were female. The sexual, physical and emotional abuse rates were 49%, 25% and 11% respectively, while 14% of them were diagnosed as pure neglect cases. The fathers were offenders in 67% of cases of physical abuse and in 9% of cases of sexual abuse. However, an extra-familial person was the perpetrator in 59% of the cases of sexual abuse. Conclusions: Recently, the number of reported CAN cases in our country has increased after the increase in the awareness of the public about this subject and multidisciplinary child protection teams have been established within hospitals. However, there is a long way to go, although remarkable improvements have been observed in the last decade. (Turk Arch Ped 2012; 47: 119-24)

Turk Pediatri Ar?ivi , 2010,
Abstract: The girl patient aged twelve had been brought to the hospital having weakness at her left side. After having fallen from a balcony, her paroxysmal headeche accompanying nause and vomiting had began. This case was cured by valproic acid. Electroencephalography showed focal slowing and deep wave discharge. This case was presented to remind that hemiplegic migraine can seldomly begin, after minor head trauma.

E3S Web of Conferences , 2013, DOI: 10.1051/e3sconf/20130137002
Abstract: A new phase transition microextraction method was developed for determination of trace amount of arsenic ions in water samples in this work. The method is based on the critical point of miscibility of solvents. In this method the mixed solution of sample and organic solvent is initially homogeneous but is separated into two phases by adding a secondary solvent (modifier). In acidic medium As(V) was complexed with ammonium molybdate, this complex was quantitatively extracted to the mixture of organic solvent (acetonitrile/methyl isobutyl ketone) before ETAAS determination. Total inorganic arsenic (III, V) was extracted similarly after oxidation of As(III) to As(V) with nitric acid. Concentration of As(III) was calculated by difference in the concentration between total arsenic and As(V). Optimization of the experimental conditions and instrumental parameters was investigated in detail. A detection limit of 0.05 μgL 1 with enrichment factor of 85 was achieved for only 5 mL of sample. The analytical curve was linear in the concentration range of 0.25-4.00 μgL 1. Relative standard deviation (RSD) for 10 replicate determinations of 2.0 μgL 1 of As(V) was 4,1%. The method was successfully applied to preconcentration and determination of arsenic in real water samples.

Abstract: The purpose of this study was to determine the relationship between performance in the Yo-Yo intermittent recovery test level 1 (YIRT1), 20-m multi-stage shuttle run test (MST) with measured maximaloxygen uptake (VOmax) in Treadmill test (TRT) and examine the differences in heart rate (HR) responses to the YIRT, MST and treadmill tests (TRT) in young soccer players. Thirteen amateur soccer players (mean age:15.38±0.51, mean height: 177.38±5.53cm, body mass 69.36± 5.48kg, VO2max 60.22 ± 1.47 ml/kg/min)volunteered for the study. Comparisons were made using ANOVA and the Pearson product moment correlation coefficient (r) was used to determine the relationship between the players’ performance and VO2. There wereno differences found among the HR values of YIRT, MST and TRT. There was found significant correlation between VO2max and both YIRT and MST performance respectively (r=.89 and r=78)(p<0.05). Both MST antYIRT could be used to determine HRmax of soccer players and also MST and YIRT have strong relationship with VO2max, thus they may also be used in order to assessment of soccer player’s endurance performance as field based test.

Balamtekin, N.,Keskin, M.,Kurto?lu, S.
Erciyes Medical Journal , 2005,
Abstract: A twenty-one–day-old-male infant presented with right ear malformation, jaundice and umbilical hernia. The patient was investigated for congenital hypothyroidism because of prolongation of jaundice and endocrinologic tests confirmed the diagnosis. It was emphasized that extra thyroidal malformations were seen more frequently in cases with congenital hypothyroidism.
Spacetimes of Boosted p-branes, and CFT in Infinite-momentum Frame

Physics , 1998, DOI: 10.1016/S0550-3213(99)00002-4
Abstract: We study the spacetimes of the near-horizon regions in D3-brane, M2-brane and M5-brane configurations, in cases where there is a pp-wave propagating along a direction in the world-volume. While non-extremal configurations of this kind locally have the same Carter-Novotny-Horsky-type metrics as those without the wave, taking the BPS limit results instead in Kaigorodov-type metrics, which are homogeneous, but preserve 1/4 of the supersymmetry, and have global and local structures that are quite different from the corresponding anti-de Sitter spacetimes associated with solutions where there is no pp-wave. We show that the momentum density of the system is non-vanishing and held fixed under the gravity decoupling limit. In view of the AdS/CFT correspondence, M-theory and type IIB theory in the near-horizon region of these boosted BPS-configurations specifies the corresponding CFT on the boundary in an infinitely-boosted frame with constant momentum density. We model the microstates of such boosted configurations (which account for the microscopic counting of near-extremal black holes in D=7, D=9 and D=6) by those of a boosted dilute massless gas in a d=4, d=3 and d=6 spacetime respectively. Thus we obtain a simple description for the entropy of 2-charge black holes in D=7,9 and 6 dimensions. The paper includes constructions of generalisations of the Kaigorodov and Carter-Novotny-Horsky metrics in arbitrary spacetime dimensions, and an investigation of their properties.
Consistent Kaluza-Klein Sphere Reductions
M. Cvetic,H. Lu,C. N. Pope
Physics , 2000, DOI: 10.1103/PhysRevD.62.064028
Abstract: We study the circumstances under which a Kaluza-Klein reduction on an n-sphere, with a massless truncation that includes all the Yang-Mills fields of SO(n+1), can be consistent at the full non-linear level. We take as the starting point a theory comprising a p-form field strength and (possibly) a dilaton, coupled to gravity in the higher dimension D. We show that aside from the previously-studied cases with (D,p)=(11,4) and (10,5) (associated with the S^4 and S^7 reductions of D=11 supergravity, and the S^5 reduction of type IIB supergravity), the only other possibilities that allow consistent reductions are for p=2, reduced on S^2, and for p=3, reduced on S^3 or S^{D-3}. We construct the fully non-linear Kaluza-Klein Ansatze in all these cases. In particular, we obtain D=3, N=8, SO(8) and D=7, N=2, SO(4) gauged supergravities from S^7 and S^3 reductions of N=1 supergravity in D=10.
M-theory PP-waves, Penrose Limits and Supernumerary Supersymmetries
M. Cvetic,H. Lu,C. N. Pope
Physics , 2002, DOI: 10.1016/S0550-3213(02)00792-7
Abstract: We study supersymmetric pp-waves in M-theory, their dimensional reduction to D0-branes or pp-waves in type IIA, and their T-dualisation to solutions in the type IIB theory. The general class of pp-waves that we consider encompass the Penrose limits of AdS_p\times S^q with (p,q)=(4,7), (7,4), (3,3), (3,2), (2,3), (2,2), but includes also many other examples that can again lead to exactly-solvable massive strings, but which do not arise from Penrose limits. All the pp-waves in D=11 have 16 ``standard'' Killing spinors, but in certain cases one finds additional, or ``supernumerary,'' Killing spinors too. These give rise to linearly-realised supersymmetries in the string or matrix models. A focus of our investigation is on the circumstances when the Killing spinors are independent of particular coordinates (x^+ or transverse-space coordinates), since these will survive at the field-theory level in dimensional reduction or T-dualisation.
Penrose Limits, PP-Waves and Deformed M2-branes
M. Cvetic,H. Lu,C. N. Pope
Physics , 2002, DOI: 10.1103/PhysRevD.69.046003
Abstract: Motivated by the recent discussions of the Penrose limit of AdS_5\times S^5, we examine a more general class of supersymmetric pp-wave solutions of the type IIB theory, with a larger number of non-vanishing structures in the self-dual 5-form. One of the pp-wave solutions can be obtained as a Penrose limit of a D3/D3 intersection. In addition to 16 standard supersymmetries these backgrounds always allow for supernumerary supersymmetries. The latter are in one-to-one correspondence with the linearly-realised world-sheet supersymmetries of the corresponding exactly-solvable type IIB string action. The pp-waves provide new examples where supersymmetries will survive in a T-duality transformation on the x^+ coordinate. The T-dual solutions can be lifted to give supersymmetric deformed M2-branes in D=11. The deformed M2-brane is dual to a three-dimensional field theory whose renormalisation group flow runs from the conformal fixed point in the infra-red regime to a non-conformal theory as the energy increases. At a certain intermediate energy scale there is a phase transition associated with a naked singularity of the M2-brane. In the ultra-violet limit the theory is related by T-duality to an exactly-solvable massive IIB string theory.
