The causes of the recent re-emergence of malaria in the East African highlands probably involve a complex interplay among multiple factors, including climate, land use, topography, inadequate use of antimalarial drugs and drug resistance, socioeconomic status, health policy and public health control measures. It is important to determine the relative contribution of these factors. In our study,...

Nowadays the study of regional groundwater resources, because of draught ,their optimal exploitation,and reducing their pollution is a vital matter. A proper way to prevent the pollution of undergroundwaters is to locate vulnerable spots and to conduct an efficient exploitation of the ground. Using thepresent models is very essential to locate and study about vulnerable spots. For this study, G...

CASE REPORT A male with cylindrical anisometropia secondary to retinal detachment (RD) surgery in the right eye (OD) was referred for contact lens (CL) fitting. His refraction was OD -1.25 -2.75 x 60 degrees VA 1.0 and OS +0.25 VA 1.2. He was complaining of diplopia with spectacles. Seven years prior to the RD surgery, he had undergone LASIK without complications. The diplopia was eliminated af...

The effects of hyperventilation on the pattern-reversal visual evoked potential (VEP) were studied in seven normal subjects and 13 multiple sclerosis patients with visual pathway involvement. Significantly greater reductions in P100 latency occurred in the multiple sclerosis patients than in controls and normalisation of the half-field response topography occurred in one patient after hypervent...

This paper describes measurements which were performed to characterize shadowing in indoor radio environments. The log-normal shadowing model has been traditionally used to characterize the large scale fading component of the received power envelope in mobile and portable radio channels [1,2]. In this research we investigated the suitability of the log-normal shadowing model for indoor radio ch...

The authors present a novel procedure for the automated rectification of side-scan sonar images. The traditional assumption of a flat seabed for the computation of the ground projection from the slant-range sonar data can later result in difficult geo-referencing and registration problems. Accurate rectification using actual seabed topography is required for precise integration of side-scan ima...

The quantification of surface structure is of major importance for several industry sectors. For the paper industry, the surface topography is essentially important for securing a good print quality of various paper grades. The surface affects various print quality parameters such as ink transfer, ink distribution, gloss and missing dots. It is thus important to have a detailed assessment of su...
