Thoracic disk herniation comprises 0.15% of all disk herniation and has various and confusing manifestations.  Among them, radicular pain down the leg could be the rarest presentation, especially if it is the only complaint. On the other hand, finding the relationship between clinical and paraclinical needs require high index of suspension and it is demanding. A 34-year-old patient, who ha...

efficient energy use in agriculture sector is one of the prerequisites to sustainable agriculture, because it allows financial savings, fossil resources preservation along with decreasing trend of air pollution. this research was conducted at the agricultural research field of zanjan university to determine the level of input energy in different tillage systems in forage maize production when i...

suitable soil structure is important for crop growth. one of the main characteristics of soil structure is the size of soil aggregates. there are several ways of showing the stability of soil aggregates, among which the determination of the median weight diameter of soil aggregates is the most common method. in this paper, a method based on adaptive neuro fuzzy inference system (anfis) was used...

The analysis of soil cultivation technologies for sowing melon crops was carried out. design a combined tillage tool capable plowing, pre-sowing treatment and formation irrigation furrows in one pass substantiated. main is recommended to be done by front plow tools smooth plowing. Plow bodies two bottom plows should mounted along the symmetry axis implement according lister scheme, which allows...

Increased yields with conservation tillage have been attributed to the conservation of soil water (Rao and Sustainable cropping systems are essential for agronomic, ecoDao, 1996; Papendick and Miller, 1977) due to decreased nomic, and environmental reasons. Data from a winter wheat (Tritievaporation and cooler soil temperatures (Gauer et al., cum aestivum L.)/summer fallow rotation experiment, ...

INTRODUCTION Disk battery ingestions can lead to serious complications including airway or digestive tract perforation, blood vessel erosions, mediastinitis, and stricture formation. CASE PRESENTATION We report a 20-month-old Caucasian child who developed eosinophilic enterocolitis and subsequent protein-losing enteropathy from manganese that leaked from a lithium disk battery. The disk batte...

Goal. Determination of the influence plow front plows on its traction resistance and operational technological indicators unit transverse profile surface plowed field. Methods. Theoretical studies were carried out using main provisions theory agricultural machines, theoretical mechanics higher mathematics. The corresponding calculations a PC in Mathcad 15.0 software environment, their graphic i...

Modern I/O subsystems have increased their capacity and density but their performance has not been improved accordingly. To address this problem, we have developed a new model that is based on the feedback information provided to the I/O subsystem controller. The presented model is applied to a multiple disk drive subsystem, which serves requests in parallel. Under conventional servicing, each ...
