Abstract: En el a o 1999, se certificó en Chile la interrupción de la transmisión vectorial de la enfermedad de Chagas. Por otra parte, el desarrollo de políticas habitacionales, que incluyen zonas rurales endémicas, han logrado importantes avances en grupos humanos que presentaban graves deficiencias de habitabilidad. En esta situación epidemiológica, se estudió 10 a os después de la terapia, a 37 chagásicos crónicos procedentes de zonas rurales de la IV Región, mediante encuesta epidemiológica (pre y post-terapia) y evaluación parasitológica (post-terapia). La encuesta incluyó: conocimiento del vector, triatominos en el domicilio actual, antecedentes de haber sido picado por triatominos y material de la construcción de la vivienda. La evaluación parasitológica se realizó mediante xenodiagnóstico (XD) (37 casos) y Reacción en Cadena de la Polimerasa (PCR) en sangre periférica (34 casos). Los resultados de la encuesta epidemiológica evidenciaron cambios importantes en la calidad de la vivienda rural de los chagásicos tratados, mientras que, en relación a la parasitemia, se detectó Trypanosoma cruzi circulante en el 89,2% de los casos (37,8% y 88,2%, mediante XD y PCR, respectivamente). Se concluye que la persistencia del parásito en condiciones post-terapia, no está relacionada con la presencia de Triatoma infestans intradomiciliario In 1999 Chile declare no vectorial transmission of Chagas disease. On the other hand, the development of dwelling policy which include endemic rural zones, have obtained important advances in human groups with height deficiency of habitability. This epidemiological situation was studied 10 years after therapy, in 37 chronic chagasic patients from rural zones of the VI Region, by an epidemiologic inquest (pre and post-therapy) and parasitological evolution (post therapy). The inquest included: knowledge of the vector, presence of triatomines in the dwelling antecedents of have been bitten by triatomines, and construction materials of the dwellings. The parasitological evolution was performed by xenodiagnosis (XD) (37 cases) and Polimerase Chain Reaction (PCR) in peripherical blood (34 cases). The results of the epidemiological survey evidenced important changes of the quality of the rural dwelling of the treated chagasic patients, while, in relation to parasitemia, circulant Trypanosoma cruzi was detected in the 89.2% of the cases. (37.8%) and 88.2% by XD and PCR respectively. It is concluded that the persistence of the parasite after therapy is not relationated with the presence of intradomiciliary Triatoma infestans
Theoretical Investigation of Local Electron Temperature in Quantum Hall Systems
N. Boz Yurda?an,K. Akgüng?r,A. Siddiki,?. S?kmen
Physics , 2012, DOI: 10.1016/j.physe.2012.02.020
Abstract: In this work we solve thermo-hydrodynamical equations considering a two dimensional electron system in the integer quantum Hall regime, to calculate the spatial distribution of the local electron temperature. We start from the self-consistently calculated electrostatic and electrochemical potentials in equilibrium. Next, by imposing an external current, we investigate the variations of the electron temperature in the linear-response regime. Here a local relation between the electron density and conductivity tensor elements is assumed. Following the Ohm's law we obtain local current densities and by implementing the results of the thermo-hydrodynamical theory, calculate the local electron temperature. We observe that the local electron temperature strongly depends on the formation of compressible and incompressible strips.
Evanescent incompressible strips as origin of the observed Hall resistance overshoot

Physics , 2010, DOI: 10.1209/0295-5075/92/67010
Abstract: In this work we provide a systematic explanation to the unusual non-monotonic behavior of the Hall resistance observed at two-dimensional electron systems. We use a semi-analytical model based on the interaction theory of the integer quantized Hall effect to investigate the existence of the anomalous, \emph{i.e} overshoot, Hall resistance $R_{H}$. The observation of the overshoot resistance at low magnetic field edge of the plateaus is elucidated by means of overlapping evanescent incompressible strips, formed due to strong magnetic fields and interactions. Utilizing a self-consistent numerical scheme we also show that, if the magnetic field is decreased the $R_{H}$ decreases to its expected value. The effects of the sample width, temperature, disorder strength and magnetic field on the overshoot peaks are investigated in detail. Based on our findings, we predict a controllable procedure to manipulate the maxima of the peaks, which can be tested experimentally. Our model does not depend on specific and intrinsic properties of the material, provided that a single particle gap exists.
Effects of olive processing waste, chicken manure and Dazomet on weeds with or without soil solarisation
Boz
African Journal of Biotechnology , 2009,
Abstract: Three non-chemical weed control alternatives (chicken manure (10 t ha-1), olive processing waste (OPW) (30 t ha-1), and solarisation (6-7 weeks at > 40.9 - 47.1oC at a 15 cm soil) were applied to greenhouse grown tomatoes alone and in combination and were compared with a soil fumigant (dazomet) for the ability to control weeds. Both dazomet (485 kg a.i. ha-1) and solarisation provided excellent control of common purslane, slender amaranth and bristly foxtail. Excellent weed control was also achieved with a half dose of dazomet (242.5 kg a.i. ha-1) plus 21 days of solarisation. OPW provided moderate control of these weeds, but chicken manure did not. OPW and chicken manure applied with solarisation provided 100% control of common purslane, slender amaranth and bristly foxtail, but did not significantly improve control compared to solarisation alone. OPW plus a short-duration of solarisation may provide weed control that is comparable to dazomet in greenhouse grown tomatoes.
Consistency of the Born Approximation for the spin-1/2 Aharonov-Bohm Scattering
M. Boz,N. K. Pak
Physics , 2000, DOI: 10.1103/PhysRevD.62.045022
Abstract: The relativistic scattering of a spin-1/2 particle from an infinitely long solenoid is considered in the framework of covariant perturbation theory. The first order term agrees with the corresponding term in the series expansion of the exact amplitude, and second order term vanishes, thus proving that Born approximation is consistent.
Correlating the Higgs and Kaon Sector CP Violations
M. Boz,N. K. Pak
Physics , 2000,
Abstract: Taking the most general two-doublet models with explicit CP violation in the Higgs sector but no phase in the CKM matrix, we determine the correlation between the Higgs and Kaon sectors using the experimental values of $\Delta M_K$ and $\epsilon_K$. It is found that: there is a direct correlation between strength of FCNC couplings and the Higgs masses, and the lightest Higgs is nearly pure CP-even, but this small CP-odd composition gives large enough contribution to $\epsilon_K$.

Efficacies of Reduced Herbicide Rates for Weed Control in Maize (Zea mays L.) During Critical Period
M.N. Dogan,?. Boz,A. ?nay
Journal of Agronomy , 2005,
Abstract: The sensitivities of Amaranthus retroflexus L., Chenopodium album L., Xanthium strumarium L. and Portulaca oleraceae L. at different growth stages were compared against two common herbicides used in maize (nicosulfuron and 2.4-D-amine). The sensitivities of weeds at 2-4 leaves growth stages were higher than at 5-8 leaves; they could be controlled by 90% with about 30-40% lower rates. Based on the results of pot experiments the performances of reduced rates were evaluated under naturally weed-infested conditions in the field experiments conducted in 2002 and 2003. Results from the experiment conducted in 2002 suggested that none of the herbicide alone provided acceptable weed control under practical growing conditions, even at the recommended rates, but the mixture of reduced rates was highly efficient against weeds. Therefore the efficacy of this herbicide mixture alone; in combination with ammonium-sulphate additive or with hand hoeing was evaluated in two field experiments under practical maize growing conditions in 2003. Results showed that low rate herbicide mixture provided acceptable weed control during critical period, provided highest grain yield and it`s efficacy against difficult to control weeds was improved by ammonium-sulphate addition.
