Abstract:

The sun vector is commonly used for defining a satellite attitude and many types of sensors exist for its determination. An attitude determination system is designed for each satellite project based on missions’ requirements. A fine pinhole sun sensor type was chosen and designed for HORYU-IV nanosatellite of Kyushu Institute of Technology. This sensor has a round-shaped hole and uses commercial off-the-shelf silicon photodiode, which consists of four small sensitive elements arranged close to each other. This type of sensors commonly uses look-up tables for providing high accuracy, which requ

Abstract:

Introduction: The Foramen Spinosum (FS), located posterolateral to the foramen ovale in the middle cranial fossa, provides passage to the middle meningeal vessels and the nervous spinosus. It is a critical landmark both surgically and radiologically. Abnormal morphology and a lack of proper anatomical knowledge of this foramen may interfere with various surgeries performed in cases of middle cranial fossa fractures, tumours and epidural haematomas. Aim: To study the various morphological variations and morphometric measurements of FS in dry human skulls from the South Bengal, India population.

Abstract:

Wheat (Triticum aestivum L.) is the main grain crop in Ningxia Hui Autonomous Region, China. A new leaf blight disease of wheat was observed in many wheat fields in Yinchuan City and Wuzhong City of Ningxia during 2020-2021. The average disease incidence of the cultivar Ningchun 50 was 5 to 15%, and there appeared the evident disease symptoms from the heading stage, then the symptoms got more serious until the mature stage. The tips of the leaves were chlorotic and turned bright yellow at the early stage of the disease. Later on, the yellow leaf spots were further spread from the tip to the pe
