Scirtothrips perseae Nakahara was discovered attacking avocados in California, USA, in 1996. Host plant surveys in California indicated that S. perseae has a highly restricted host range with larvae being found only on avocados, while adults were collected from 11 different plant species. As part of a management program for this pest, a ‘‘classical’’ biological control program was initiated and...

Reconstructing a 3Dmodel of a human face fromamonocular video sequence is an important problem in computer vision, with applications to recognition, surveillance, multimedia, etc. However, the quality of 3D reconstructions using structure frommotion (SfM) algorithms is often not satisfactory. One of the reasons is the poor quality of the input video data. Hence, it is important that 3D face rec...

We present the results of an analysis of ultraviolet observations of T Tauri Stars (TTS). By analysing emission measures taken from the literature we derive rates of ionizing photons from the chromospheres of 5 classical TTS in the range ∼ 10 41 –10 44 photons s −1 , although these values are subject to large uncertainties. We propose that the He II/C IV line ratio can be used as a reddening-in...

Background and Aims: Evaluation of the prevalence of transfusion-transmissible infections (TTIs) in blood donors is a valuable index of donor selection and blood safety. This study was conducted to explore the prevalence and trends of TTIs markers and study of confidential unit exclusion )CUE) option among blood donors in Kurdistan province in the west of Iran. Materials and Methods: We conduc...

For an optimum use of natural resources in the sustainable development trend, there is a need to identify ecological resources in the shortest period of time and minimum possible cost. In this article, we aimed Management ecosystem by Assessment of plant covers changes at Taleghan Township in a twenty year period. Percentage of landscape and number of patch were among the metrics that were calc...

BackgroundEach year about 32.4 million of children are born with low birth weight, which is below the 10th percentile for their gestational ages; moreover, about fifteen million of them are premature. Actually, about 60% of neonatal deaths occur in low birth weight neonates related to their prematurity. This study aimed to determine the neonatal death rate and the most common causes of the hosp...

OBJECTIVES To analyze esophageal cancer incidence and pathological data of Zhongshan in China in 1970- 2007, and to provide scientific information for its prevention and control. METHODS From Zhongshan Cancer Registry esophageal cancer incident and pathological data were obtained. Pathological proportions and trends were calculated and analyzed. RESULTS Although there was a continuously and...
