On some electroconvection models

We consider a model of electroconvection motivated by studies of the motion of a two dimensional annular suspended smectic film under the influence of an electric potential maintained at the boundary by two cylindrical electrodes. We prove that this electroconvection model has global in time unique smooth solutions

Perforated small intestine in a patient with T-cell lymphoma; a rare cause of peritonitis

The nontraumatic perforations of the small intestine are pathological entities with particular aspects in respect to diagnosis and treatment. These peculiarities derive from the nonspecific clinical expression of the peritonitis syndrome, and from the multitude of causes that might be the primary sources of the perforation: foreign bodies, inflammatory diseases, tumors, infectious diseases, etc. Accordingly, in most cases intestinal perforation is discovered only by laparotomy and the definitive diagnosis is available only after histopathologic examination. Small bowel malignancies are rare; among them, lymphomas rank third in frequency, being mostly B-cell non Hodgkin lymphomas. Only 10% of non-Hodgkin lymphomas are with T-cell. We report the case of a 57 years’ old woman with intestinal T-cell lymphoma, whose first clinical symptomatology was related to a complication represented by perforation of the small intestine. Laparotomy performed in emergency identified an ulcerative lesion with perforation in the jejunum, which required segmental enterectomy with anastomosis. The nonspecific clinical manifestations of intestinal lymphomas make from diagnosis a difficult procedure. Due to the fact that surgery does not have a definite place in the treatment of the small intestinal lymphomas (for cases complicated with perforation), and beyond the morbidity associated with the surgery performed in emergency conditions, prognosis of these patients is finally given by the possibility to control the systemic disease through adjuvant therapy

Analyzing domain shift when using additional data for the MICCAI KiTS23 Challenge

Using additional training data is known to improve the results, especially for medical image 3D segmentation where there is a lack of training material and the model needs to generalize well from few available data. However, the new data could have been acquired using other instruments and preprocessed such its distribution is significantly different from the original training data. Therefore, we study techniques which ameliorate domain shift during training so that the additional data becomes better usable for preprocessing and training together with the original data. Our results show that transforming the additional data using histogram matching has better results than using simple normalization.Comment: This preprint has not undergone peer review or any post-submission improvements or corrections.

Designing a mathematical model to optimize the size activities in the production plan for SC RENTEA SRL

Planning is the process of identifying the present situation, setting goals and define ways to achieve the objectives. Planning is the primary function of business management because of time preparing space for all other aspects of management, is considered a link between past and present [2]. Use of computer technology in agriculture will have a significant effect, provided achieving integrated information systems at macro (national agriculture, ministry) and micro (farm, farms etc.). Expanding use of computers in agriculture will ensure rational use of resources, their savings, the provision of complete and operative information on the conditions of production, the supply-sales market, the cost on profitability, etc. Thus, this work demonstrates the need and applicability of computer systems at the level of companies

Subsistence and semi subsistence agriculture in Romania

The paper aims to analyze the main question that arises in the context of current agricultural policies: are households farms really? Viewed from the perspective of sustainable development of rural areas, the answer becomes very important, especially given that the actual short comings rural employment opportunities and business development. Research is needed, especially given the new Common Agricultural Policy for the period 2014-2020 still provides annual grants (between 500-1000 euros), especially given that you want to implement a policy of restructuring. In order to eliminate the sector subsistence farmers producing for own consumption only occasionally provides a scheme for granting annuities 2020 for owners who will give lands on lease or be sold to commercial farms and co financing up to 15,000 euros for starting a business

Use planning analysis on agricultural holdings according to their physical size. Case studies

The processes of planning of the production activity of agricultural holdings are, in fact, a number of activities to study the alternatives and choose the optimal Variant. It is conducted on the basis of the theory of planning by the manager/administrator and seeks to provide for a high efficiency of work, to develop and refine the tools, techniques and levers for the conduct of competition on the market, to reduce the uncertainty, to ensure management and control instruments in crisis situations, etc
