Abstract:Limb amputation is one of the oldest mutilating surgeries in the world.. It is a delicate and complex medical operation, also on the functional level of the human body. Otherwise, the amputation equipment is multiple, In the case of short femoral stump, femoral amputations are often close to the, overlying articulation, with healing problems and short stump. It is very difficult to obtain an optimal rehabilitation in these patients by a traditional prosthesis. However, according to the Osseointegration principle, the prosthesis anchored directly into the bone is attached to the residual limb, without the use of any hold, eliminating all problems related to safety, heat, perspiration, and discomfort. Indeed, different systems have been developed for for bone anchored prostheses and different approaches have been used to obtain a stable fixation between the implant and the bone. The objective of this work is a comparative study between the different types of orthopedic implants developed by the manufacturing laboratories as well as their influence on the osseointegration process.
Abstract:Populus tremula L. trees from aspen forest stand of the State Regional Natural Reserve “Molokcha botanical and entomological reserve” (Moscow Region) have been studied. Such factors as conditions of growth, taxation characteristics, rates of annual rings formation, viability and resistance to Phellinus tremulae, drought intervals and climate impact have been analyzed. Influence of rot on increment formation has been studied. To do it selected trees have been categorised into two groups - damaged and not-damaged by rot. Average chronologies were constructed for them. The analysis showed that the trees of selected groups reacted similarly on the change of ecological factors. There has been no difference in radial increment rates between diseased and vigorous trees, polymorphism existing in the population is related to genetic difference between trees in terms of rot resistance. There is a certain period of 11 years in abnormally narrow annual rings formation. While analysing the influence of climatic factors on radial increment formation in our stand we can state that the most unfavorable impact on wood formation is caused by draught at the beginning of the vegetation period prior to the year of annual ring formation. There is a tendency for being less draught-resistant for diseased trees.
Abstract:Two field experiments in sand soil mixing with taflla in 7:1 ratio in experimental farm at Nuclear Research Center, Atomic Energy Authority, Inshas, Egypt during the two growing seasons of 2016/2017 and 2017/2018 under dripper irrigation to study the effect different phosphate fertilizer level i.e. (50, 100 and 150 kg fed-1 of calcium superphosphate (15.5 % P2O5) at with or without mycorrhiza inoculation on economic onion yield and one nitrogen fertilizer level at 60 kg N fed-1 in form of ammonium sulfate (21.2% N) 15 N labeled 5% atom excess. Results revealed that, the application of 150 kg fed-1 calcium superphosphate (CSP) with mycorrhiza inoculation provided in significant increases of fresh and dry of onion plant. In the same direction, phosphorus concentration in root, shoot and blub in onion during two growing seasons. Onion yield was significantly affected by phosphate fertilizer with mycorrhiza inoculation but there was no statistically significant difference between two level of 100 and 150 kg fed-1 calcium superphosphate (CSP) with inoculated plant. The maximum economical yield was 13172 & 13385 kg fed-1 during two seasons respectively in treatment mycorrhiza inoculated with level 150 kg fed-1 CSP. Nitrogen utilization percentage values were 46.87 % and 44.81 % for application full rate of 150 kg fed-1 CSP with mycorrhiza inoculated during two seasons respectively. Higher values of available phosphorus in soil rhizosphere and mycorrhiza infection of root were significantly affected by level of 150 kg fed-1 CSP. Arbuscular mycorrhiza fungi (AMF) infection percentage in plant roots greatly affected by AMF inoculation of the sampling periods of 60 and 90 days from planting. The benefits of AMF inoculation are greatest when soil is at 100 kg fed-1 CSP with reverse correlation between available phosphorus in rhizosphere and mycorrhizal colonization
Abstract:Internet of Things (IoT) has emerged as a promising technology in a wide range of applications such as healthcare and information technology. However, despite the advancement of the technology, several challenges in terms of security and maintaining integrity of data exist in IoT. The most significant threat observed in these systems were found to be distributed denial of service (DDoS), selective forwarding attack etc which makes the server resources unavailable to the user. Therefore, this paper has focused on generating a new selective forwarding attack detection in comparison to the existing defensive approaches developed against this attacks. Methodology used in this paper for the prevention of the attacks is multi level trust based scheme. Furthermore, by conducting an exhaustive review on the existing techniques for the prevention of the attacks it was found that implemented scheme has better performance than existing techniques in terms of throughput, overhead, detection accuracy, power consumption and energy consumption.
Abstract:Facial expressions play a pivotal role in human communication as they convey feelings and emotions, hence, enhancing communication. Emotion recognition technology involves the application of computer vision as an interface between the human and the computer, to help decipher one’s feelings. The systems use various algorithms to help carry out their tasks in understanding and interpreting an individual’s facial expressions. Besides, emotion detection plays a focal role in projects relating to affective computing. Affective computing, on the other hand, is concerned with the development of systems and devices which can recognize and interpret human affects. The technology finds applications in several industries including healthcare, mobile devices, social media, and market research. This paper aims at exploring the technology, giving a history of the same, current applications of the technology, outlining some of the technical limitations associated with it, as well as offering a future direction of the same.

Abstract:In Environment conditions of Azerbaijan the Codling moth is the most dangerous insect pest of walnut fruits plantations, where the insects develops in two full insect generations. Walnut fruits damages mainly by insects belonging to second generation. Liotryphon caudatus Graw and Pimpla spuria L. are the natural enemies of codling moth, which activities mainly occur during first generation of Codling moth. Application of linear programming showed that to protect natural enemies of Codling moth and reduce damage of walnut fruits, insecticide application with consumption rates 400ml/ha of Ambush must be concentrated to caterpillars of second generation of Codling moth. For the reduce first generation of insect pests additionally to insecticide application necessary use insect traps against butterflies of Codling moth.
Abstract:Objective: The aim of rectal cancer surgery is to apply surgery with good functional results without compromising oncological surgery. Good oncological and functional results can be obtained with more limited surgery in early stage rectal cancer and premalignant lesions. Background: The aim of this study was to discuss the results of transanal endoscopic microsurgery applied to cases of rectal mass in the light of the relevant literature. Material and methods: The study included patients with early stage rectal cancer and premalignant masses who presented at our clinic between January 2016 and January 2018. Preoperatively, histopathological examination and clinical staging was applied. Transanal endoscopic microsurgery was applied to T1 cases and those where the polyp could not be removed with colonoscopy. Results: Transanal endoscopic microsurgery was applied to 34 patients, comprising 65% males and 35% females. The length of stay in hospital was mean 20±10 hours. In the histopathological examination, invasive cancer was determined in 8 cases. The surgical margin was >6mm. All the cases were examined with rectosigmoidoscopyat 3 months postoperatively. Conclusions: In transanal treatment of early stage rectal cancers and premalignant masses, transanal endoscopic microsurgery can be applied successfully. This technique has good oncological and excellent functional results. Although the learning curve is long, this is an applicable method.
Abstract:Objective: Obesity, hypertension and dyslipidemia are increasing in prevalence worldwide, and are closely linked to cardiovascular diseases. In this study we aimed to compare the prevelance of atherogenic dyslipidemia and dipper, non-dipper hypertension in patients with grade 1 obesity.\nMaterial and Methods: A total of 272 patients (female n:180, 68.2%) with grade 1 obesity followed up for essential hypertension who did not have a history of hypolipidemic drug use were included in the study. Patients had atherogenic dyslipidemia high triglyceride levels, high-density lipoprotein levels were low and low-density lipoprotein levels were high-normal.\nResults: Atherogenic dyslipidemia prevalence was higher in non-dipper hypertension group (n: 84, 67.0%) than patients with dipper hypertension group (n:28, 18.9%) which was also statistically significant (p=0.03).\nConclusion: It is established in our study that atherogenic dyslipidemia may be a factor playing role in non-dipper hypertension patients with grade 1 obesity. Effective treatment of atherogenic dyslipidemia may result in the improvement of non-dipping status.
Abstract:Purpose: To determine the deviation of pelvic floor muscles (PFM) activity from the normal in children with primary monosymptomatic nocturnal enuresis (PMNE).\nMethods: Thirty-six boys (18 with PMNE and 18 age-matched normal boys) ranged in age from 8 to 10 years, participated in this study. They were assigned into one of three age-matching categories based on age; 8, 9, and 10 years categories in both PMNE and age-matched normal groups. Peak and speed of PFM activity were detected by using surface electromyography (sEMG) with endo-anal sensor for each child with PMNE and compared to its corresponding values in normal age-matched individuals.\nResults: Both peak and speed of PFM activity have significantly decreased in children with PMNE from their age-matched normal children, as the percentages of decline from normal peak were 54.8%, 54.2%, and 53.5%, and those from normal speed were 73.6%, 70.5%, and 66.7%, for age-matching categories children aged 8, 9, and 10 years old respectively.\nConclusions: In children with PMNE, the urinary dysfunction affects the PFM by suppressing its activity.
