Published: March 2023

Purpose: of the study is to develop and introduce into the training process of young boxers aged 15-16 years a program for the development of speed-strength qualities during the annual macrocycle. Material and methods. The study involved boxers aged 15-16 years in the amount of 24 people, whose level of fitness was II and I sports category. The sportsmen were divided into control and experimental groups (12 sportsmen in each). The study used the determination of indicators of the absolute and relative strength of hits, as well as special explosive work of the muscles of the upper limbs (test 8 s, number of hits, total tonnage, work power, explosive endurance coefficient, creatine phosphate working capacity index, index explosive endurance), using chronodynamometry «SPUDERG-10». Results: to conduct the study, an experimental program was developed to develop the speed-strength qualities of young boxers aged 15-16 during the annual training. A feature of the construction of the experimental program is the distribution of means of speed-strength training in microcycles, which are used at the beginning and end of the training session. When introducing the experimental program, a change in the indicators of absolute and relative strength of young boxers aged 15-16 was established under the influence of classes under the Youth and Youth Sports School program (control group) and according to the experimental program. So, between the groups, a significant difference was obtained in favour of the experimental group in the absolute force manifested in the side kick (t=2,20; p<0,05). Along with this, in all the studied indicators, the boxers of the experimental group significantly (p<0,05-0,01) increased the results during the annual training. Conclusions. The comparison of the generalized results of the indicators of special explosive work of the muscles of the upper limbs during the pedagogical experiment revealed that all the studied indicators improved in both groups, but more significant changes were obtained in boxers who carried out the training process according to the experimental program. Significantly better results in relation to the control group obtained in total tonnage (t=2,90; p<0,05), work power (t=2,56; p<0,05), explosive endurance coefficient (t=2,27; p<0,05) and creatine-phosphate performance index (t=2,29; p<0,05).

Published: March 2023

Purpose: To provide immuno histo chemical characterization of sub retinal bands removed during retinal surgery in eyes with proliferative vitreo retinopathy (PVR). Methods: This study included all eyes with the clinical diagnosis of PVR that underwent pars plana vitrectomy surgery during which the subretinal tissue causing retinal detachment was obtained. The subretinal bands were removed “en bloc” through retinotomy using subretinal intraocular forceps. The excised tissue was sent for histopathologic analysis. Immunohistochemistry (IHC) was performed to confirm the cellular nature and components of these subretinal membranes. The IHC stains included, glial fibrillary acidic protein (GFAP), Pancytokeratin, CD3 CD20 CD68 and CD34. Results: Subretinal membranes (SRMs) from 7 eyes were included in the analysis. All cases had successful surgical outcome with reattachment six months after surgery. The microscopic examination of the excised tissue nicely demonstrated the constituents of the SRM as follows: retinal pigmented epithelial (RPE) cells that stained positively with cytokeratin (7/7), avascular plaques of RPE cells showing metaplasia in the form of spindle cells (7/7). Fragments of gliotic GFAP-positive neural retina was adherent to the fibrous plaque (6/7). Bruch’s membrane was identified in one specimen. CD68 positive macrophages were seen in (5/7) being silicon oil- laden macrophages in2/5. Rare CD3 positive cells were also noted in 1 specimen. Conclusion: Subretinal bands in PVR are mainly composed of reactive avascular plaques of RPE metaplasia and macrophage infiltration. The overlying gliotic retina or Bruch’s membrane are likely to be adherent to such plaques and might be inadvertently excised during removal of such membranes. Removal of SRMs is essential for successful reattachment of the retina.

Published: March 2023

Purpose: Purpose of this study is to determine the effect of weight and height on intraocular pressure (IOP) and to compare effect of height and weight on IOP in males and females. Methodology: This cross-sectional study was carried on 114 subjects through non-probability convenient sampling technique, both gender and age ranging from 15 to 30years who had not undergone any ocular surgery or medical treatment for hypertension glaucoma diabetes. The data collected from the patients at the department of ophthalmology during time of 8am-2pm in Madinah teaching hospital, Faisalabad in duration of 7months from January 2018 to August 2018. Data was collected after taking consent and extensive history. Visual acuity was tested by using Snellen chart and IOP measured by Air puff tonometer and weight measured by weight machine in Kgs and Height measured by Hight scale in feet. Data was noted on Performa. Data was analyzed by using test multiple linear regressions by using SPSS version 20. Result: Total number of studied individuals were 114, 48(42%) males and 66(57.9%) females with age ranges from 15-30 years. Weight and Height was measured and tested relation with IOP and gender by using Linear multiple regression test. Analysis shows that relation of weight and IOP is significant (p<0.001) with mean of IOP 17.432±3.4397 and weight 57.71±12.774. Weight is more affected the males then females statistically. Height and IOP weekly related statistically (p<.794) with mean of height and IOP 5.306±.2159 and 17.432±3.4397. Height is also weekly affect IOP in females then males. Conclusion: The weight is strongly affecting the IOP then height. Males have larger height and high weight so they affect the IOP more than females according to gender. In clinical practice it can allow to test IOP in highly weighted patients.
Orbital emphysema with loss of vision following undiluted intravitrel perfluoropropane administration
Authors: Aziz Ahmad , Nagendran Sonali , Perry Mike , Lee Vickie
Published: March 2023

We present a case of orbital emphysema leading to orbital compartment syndrome and permanent visual loss secondary to expansion of perfluoropropane (C3F8) gas, which was injected into the vitreous cavity as a gaseous tamponade during vitreoretinal surgery and inadvertently undiluted. Orbital emphysema leading to orbital compartment syndrome resulted in visual loss despite treatment with lateral canthotomy, cantholysis and surgical decompression. Orbital compartment syndrome is an ophthalmic emergency and should be treated immediately with lateral canthotomy and cantholysis. There is little literature on the management and outcomes of orbital compartment syndrome with expansile gases such as C3F8 which may quadruple in volume within 96 hours. Hyperbaric oxygen has been reported to be of benefit but patients may require orbital decompression for definitive treatment. Although orbital emphysema with air rarely threatens vision orbital emphysema with expansile gases can lead to orbital compartment syndrome and visual loss.

Published: March 2023

Food additives are factors in both health reason and food production. Sweeteners are utilized in large scale because of biochemistry, production, obesity, food structure, economy, functional property, and research and development efforts of food industry. Intake of high calorie nutrients such as sugar in the nutrition are important factors against increasing trends of obesity, cardiovascular disease and diabetes and some of chronic diseases. In healthy nutrition, the sufficient calorie intake must be recommended for basal metabolism and usual daily activities due to individual and environment conditions. Sweeteners are also food additives and using commonly for low calorie nutrition or from other reasons such as bulk of foods. natural sweeteners can be suggested such as stevia, together with balanced and low calorie diet including vegetables, and other food types due to diet originality that change in different societies, economies, regions and education levels of people. Traditional nutrition such as Mediterranean diet can be recommended for balanced diet. This topic was reviewed under light of literature.

In this study, the researcher reviewed the literature regarding the inflammatory nature underlying initiation and progression of diabetes. Although several studies have addressed the existence of inflammatory nature of diabetes either type 1 diabetes or type 2 diabetes, clinical implications of such therapeutic strategies are not involved in guideline of diabetic therapeutic strategies. Due to the importance of diabetes as a health problem that impacts the world, this review is an attempt to raise crucial questions regarding considering in clinical practice the involvement of anti-inflammatory medications seriously and to conduct more clinical and basic studies to confirm the same issues.
Vitamin C and obesity: problems and solutions
Authors: Marks Ray
Published: March 2023

Obesity, a largely intractable health condition with incalculable health and financial and social costs and ramifications remains an immense challenge to mitigate effectively. Multiple interventions to offset obesity, and to mitigate its negative impact, while studied and implemented for many years, have generally failed to eliminate this growing global epidemic. Alternately, interventions that can limit the onset of obesity, or help to reduce this where present, including efforts to contain pain, depression, and lack of energy, would appear of high significance. Studied for over 40 years, various anti oxidants are proving to be of possible adjunctive benefit in efforts to reduce excess weight, and associated inflammatory responses, pain, and depression that are encountered by overweight persons. This mini review discusses some findings regarding vitamin C or ascorbic acid, a key ingredient of fruits and vegetables, and whether more emphasis on ensuring adequate vitamin C intake has a possible role in attenuating selected correlates of the global obesity burden. Extracted from current literature, it is concluded that this is a field of significant promise, but one requiring more insightful research, multiple intervention approaches, and dedicated collaborators.

Authors: JM Jbireal , Elsayed Azab Azab , S Alzahani , M Elshareef
Published: March 2023

Background: Chronic myeloid leukemia (CML) is a clonal myeloid proliferative disorder of primitive haemopoietic progenitor cells. The incidence of CML ranges between 10 and 15 cases/106 /year without any major geographic or ethnic differences. Imatinib mesylate provides good results in the treatment of CML. Early studies demonstrated that Imatinib mesylate can produce clear hematologic and cytogenetic response when used as a treatment of CML patients with positive BCR-ABL gene. Nevertheless, some patient with different stages of CML (chronic, accelerated, or acute phases) either relapse or stay unchanged for a long time after initial doses of treatment. This phenomenon led to the fact that we must explore the possible changes expected to appear if we make some changes in the treatment strategy. Objectives: The present study aimed to evaluate hematologic and molecular responses of CML patients to Imatinib mesylate treatment. Methods: Eighteen CML patients in chronic phase aged (24–65 years) males and females were treated with Imatinib mesylate (400, 500 or 600 mg/day) for sixteen months. Hematologic and cytogenetic changes were analyzed periodically. Results: Overall 18 cases, hematologic response of 14 cases was complete white blood cells (WBCs) decrease to normal range within 4 months) with P value of less than 0.0001 whereas in 4 cases WBCs were decreased slowly (after 8 months). A major cytogenetic response was noticed in 4 cases while in others the response was partially or in minor range. The major hematologic and cytogenetic response was noticed when using 600mg/day of Imatinib mesylate. The correlation appeared as a significant positive correlation between the treatment doses and Hb, hematocrit, MCV, MCH, esinophils%, and monocytes %. And a significant negative correlation between the treatment doses and RDW %, platelets count, WBCs count, and basophils %. On the other hand, no correlation between the treatment doses and RBCs Count, MCHC, Neutrophil % and BCR/APL ratio % Conclusion: It can be concluded that treatment of CML patients with Imatinib mesylate caused complete WBCs decrease to normal range. The major hematologic and cytogenetic response was noticed when using a higher dose of Imatinib mesylate.

Published: March 2023

Background: Myelodysplastic syndromes (MDS) can represent a challenge in diagnosis and treatment because of heterogeneous presentation, unpredictable response to variable measures with propensity for leukemic transformation. Aim of study: To review MDS Iraqi patients in term of presentation, risk stratification and treatment options and to assess outcome of different treatment options in term of response criteria, quality of life and progression. Patients and method: a hospital based study conducted over a period of 21 months from January 2018 till October 2019 in different hematology centers in Baghdad. Any patient with primary or therapy related MDS diagnosed were enrolled in this study. Each patient stratified into different risk groups when applying cytogenetic versus non cytogenetic scoring systems, the therapeutic options for every patient. They observed for their response to different therapeutic modalities and any evidence of progression. Results: Mean age at diagnosis for MDS was 58.7± Anemia was the most common presenting symptom representing 68.4% of patients. MDS with excess blasts-II is forming 28.8%. Majority of patients categorized as intermediate risk group. Hypomethylating agents used for 50% of MDS patients while 32.1% received best available therapy. Those on HMA achieve partial remission in 7.1%, 25.2% reached to stable disease, hematological improvement in 25.2%. Death outcome in 21.6 with a mean survival is 7.7 months. Disease progression in 10.8%, 7.2% showed leukemic transformation. Conclusion: Iraqi MDS patients present at younger age with advanced manifestation that needs standard risk stratification. The non-cytogenetic score systems can't be of equivalent application even low resources circumstances.

Published: March 2023

Background: Whole blood (WB) can be superior to red blood cell (RBC) solutions for transfusion in hemorrhage because it contains coagulation factors and platelets. A previous study reported that the quality of an RBC solution and WB can be maintained during transport by an uncrewed aerial vehicle (drone) at normal temperature. Therefore, we aimed to determine whether this approach could also be used for transport of WB for cases of massive bleeding on the hot and cold days that occur in Japan, by testing this approach twice, on hot and cold days. Method: We used an automobile-transported WB packs obtained by phlebotomy and corresponding segments to a test place in Tomi at a distance of approximately 200 km from Tokyo. Subsequently, a drone (M1000) flight transported the WB and its segments. Results: The influence of the drone flight on WB appeared to be minimal on lactate dehydrogenase (LDH) level, and the WB was confirmed to be problem-free in coagulation tests. Conclusion: We transported WB by the drone and confirmed that there were little hemolysis of the WBs and little reduction in the levels of coagulants.

Published: March 2023

Background: Cervix cancer is one of the most common cancers in women worldwide, and is the third most common malignant disease in women. It is one of the main health problems in Libyan women. Blood act as a pathological reflector of the status of exposed patient to infections and other conditions. Laboratory tests on the blood are vital tools that help detect any deviation from normal in the human body As the disease progresses, changes appear in haematological parameters which have been of relevant consideration in context of cancer patients. Objectives: The present study aimed to evaluate the alterations in haematological parameters among cervical cancer patients in Sabratha National Cancer Institute. Subjects and methods: The present study was conducted on 150 cervical cancer patients, attending the National Cancer Institute of Sabratha from the 11th February, 2006 to the 3rd February, 2020. This study was approved by the Research and Ethical Committee of Sabratha University and Sabratha National Cancer Institute. Age was extracted from patient files. Also, 60 healthy individuals without any chronic disease were recruited for the control group. Blood samples were collected by vein puncture, 3 ml of venous blood withdrawn from each participant in the study by using disposable syringes under aseptic technique; they then transferred to a sterile EDTA tube, for complete blood count. The statistical significance of differences between groups was evaluated with the Mann Whitney U test. Results: The results showed that the mean age of the cervix cancer patients was 53.37±11.6 years. RBCs count, hemoglobin concentration, Hct value, MCH, MCHC, and lymphocytes % were significantly (P<0.01) decreased compared with the healthy individuals. On the other hand, leukocytes and platelets count, mixed %, neutrophils %, PLTs/Lymph, and Neutrophils/Lymphocytes ratios were significantly increased as compared with the healthy individuals. Conclusion: It can be concluded that a significant increase in leukocytes and platelets count, mixed %, neutrophils %, and the studied inflammation related haematological parameters and a significant decreased in lymphocytes %, RBCs count and most its indices. Further haematological studies are needed to confirm these results. Also, there is need to routinely monitor the haematological parameters and among cervical cancer patients.

Published: March 2023

Carbon monoxide poisoning (CO) nicknamed “Silent killer” remains the leading cause of poisoning deaths in most countries. In Tunisia, an estimated number of 2000 to 4000 cases of poisoning was noted per a year with an estimated percentage of death up to 90% at the site of intoxication. This intoxication is very exceptionally complicated by a compartment syndrome that can aggravate the functional and vital prognosis when it is dominated by other symptoms, particularly neurological ones. We report the case of a patient who presented a compartment syndrome during CO intoxication that evolved favorably.
Guiding principles and laws in the interpretation of postmortem findings
Authors: Komolafe Akinwumi O
Published: March 2023

The postmortem examination is fundamental to the practice of medicine. This important aspect of medical practice is crucial for the understanding of principles of medicine and pathophysiologic phenomena. The autopsy is however bedeviled by subjectivities which are largely tied to the attending pathologist’s experience and idiosyncrasies. Subjective rather than objective deductions may lead to wrong conclusions with far reaching consequences in the adjudication of justice and public health issues. It is therefore highly imperative to have ground rules, laws and principles by which observations can be interpreted appropriately; devoid of the whims and caprices of specialists in anatomic pathology.

Published: March 2023

Antibiotic resistance has become a global concern as the clinical efficacy of many existing antibiotics is being threatened by the emergence of multidrug resistance pathogens. Phyllantusamarus has been showing to possess various properties including antibacterial property by many authors. This study was therefore designed to investigate the antibacterial effects of aqueous and methanolic extract of Phyllantusamarus on urinary tract pathogens. 10g of the concentrated extract from methanol and aqueous was simultaneously dissolved in 100ml of water and used to make two-fold dilutions, to give100, 50, 25, 12.5, 6.3, 3.2, 1.6 and 0.8mg/ml as extract concentrations. 10 different concentrations, 12.5, 6.3, 3.2, 1.6, 0.8, 0.4, 0.2, 0.1, 0.05mg/ml and 5µg/ml, of the control drug ciprofloxacin were also prepared. The phytochemical constituents of both methanolic and aqueous extract were also investigated. Fourteen isolates from urine sample were identified. These isolates, Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Klesiella pneumonia, Enteroccocusfeacalis, Proteus mirabillis, Staphylococcus saprophytic sand Control standard Escherichia coli ATCC 25922 were subjected to antibacterial effect of varying concentration of these methanolic and aqueous extract of phyllantusamarus and standard drug ciprofloxacin using agar well diffusion method. The diameter in millmiters of the inhibition zones was measured, the Minimum Inhibitory Concentration and Minimum Bactericidal Concentration were also determined. The data obtained were analysed using SPSS version 17. The extract was found to containsaponins, flavonoids, alkaloids, tannins, phlobatanins and terpenoids. Both aqueous and methanolic extract of P. amarus caused a concentration dependent increase in zones of inhibition of the growth of the isolates. The MIC and MBC values were however found to be high compare to the standard. There was no significant different between Agar well diffusion method and disc diffusion method. The study clearly showed that P. amarus has appreciable antibacterial properties. However, there is need for improvement in approaches for natural product isolation and characterization so that the bioactivity and potency of the drug can be improved upon.
Nutrition from biblical Adam to the present time
Authors: Sima Petr , Vetvicka Vaclav
Published: March 2023

Background: The purpose of this review is not to defend or disprove the generally accepted belief that for maintaining their health, humans need prebiotics in the form of a dietary fiber, most of all vegetable fiber. This view is so deeply rooted among both experts and the general public that it can be almost comparable to a dogma of faith. It is not surprising that it is also a subject of never-ending fight between advocates of various forms of vegetarianism and advocates for eating meat. We are trying to answer the question of who is right; or is the truth somewhere in the middle? What exactly are prebiotics? A common definition suggests that prebiotic is an indigestible part of food, which supports growth or activity of intestinal micro flora and, therefore, improves health status of the consumer. The first prebiotic in our life is lactose. Vegetable-based prebiotics appear in our food later. They provide no energy for the organism, but serve as a substrate for intestinal microbiota, support peristaltic, adsorb water, and bind cholesterol and lipids.

Published: March 2023

Introduction: Melioidosis is a tropical disease caused by Burkholderia pseudomallei. Endemic in Southeast Asia and northern Australia. It mainly affects adults with risk factors for the disease. The data are limited to the pediatric population. Case report: 6-year-old male patient. Current condition: It is sudden on set with a fever of 39°C and 40°C, with no predominance of time, accompanied by right parietal headache. For cerebrospinal fluid results, compatible with meningeal tuberculosis, treatment for tuberculosis is initiated. With positive cerebrospinal fluid culture to Burkholderia pseudomallei, treatment for tuberculosis are suspended and Meropenem and Trimethoprim with Sulfamethoxazole are given. The patient dies the day after the specific treatment is started. Postmortem infection is confirmed by Burkholderia Pseudomallei, with a cerebrospinal culture and blood culture. Discussion: It is worth highlighting the importance of improving awareness and recognition of Melioidosis.

Published: March 2023

Background: Transfusion Medicine safety is held by regulations and government legislation inside a total quality frame. In order to develop a quantitative quality planning in the serological screening of seven infectious markers in blood donations, a cross-sectional, study was conducted. Methods: We performed the quality design in Bio-Rad’s xMark microplate spectrophotometer by ELISA for HBsAG, anti-HIV, HTLV-1/2, SYPHILIS and HBcAb; and CHAGAS, and HCV with Bio-Rad and Biokit antibodies, respectively. The guide CLSI EP-12 was used to evaluate the imprecision for each marker. The minimal concentration for each marker from a seropositive asymptomatic donor registered on e-Delphyn® was used to determine the quality requirements, the sigma metric, and the ΔSE. Results: The values found by the sigma metric calculi were 7, 7, 4, 4, 5 and 4 for anti-HIV, HBcAb, HBsAg, HCV, HTLV-1/2, SYPHILIS and CHAGAS, respectively. All Ped near 0.90 had 0.03 or less. The quality control procedures for the qualitative ELISA guarantee a good sensibility. With the statistic control cards, it was possible to select rules with high Ped and low Pfr for each serological marker. Conclusion: we shown a quantitative quality planning during the serological infectious screening of blood donations demonstrating different sigma levels at Peruvian Hospital. The development of strategies to diminish the uncertainty by donation and will secure the safe transfusion of units that will save lives.
Skin line and subcutaneous fat in radiology: Opinion
Authors: Alahmari Abdulwahab
Published: March 2023

The aim of this paper is to shed light on a neglected topic in radiology which is imaging the skin and subcutaneous fat. A few studies showed that imaging of skin line and subcutaneous fat have clinical benefits for health, cosmetic reasons, and overall wellbeing. This paper will list many issues that can be diagnosed when evaluating a skin line, fold, and subcutaneous fat on different imaging modalities like; X-ray, ultrasound, CT, MRI, etc. Furthermore, this paper will show a comparison of those imaging modalities in terms of measurement accuracy, diagnosis of skin and subcutaneous fat diseases, comparison of males and females in terms of fat buildup, and so on. According to the available literature, men have more fat than women in the inner deep layer, but women have more body fat than men. Furthermore, as previously hypothesized and proven wrong, recent paper shows that there is no water in the adipose tissue. In addition, a hierarchy in evaluating skin folds and subcutaneous fat by using imaging modalities is seen in the following order from low accuracy to high accuracy; caliper, X-ray, ultrasound, CT, etc.

Kiza-ntenga syndrome
Authors: NTENGA Patrice
Published: March 2023

The nervous system (NS) in its complexity still has some surprises in store for us. The developmental disorder of the NS during the embryonic period is at the origin of malformations of cortical development (CDM) which represent a major cause of mental and motor handicaps as well as severe epilepsy. Many anomalies of the latter (SN) are not yet described and will continue to be described over time given the significant advances in science observed in recent years. We describe here a syndrome called Kiza-Ntenga syndrome which would be strongly of embryonic origin and which is made of right cerebral hemiatrophy, facial asymmetry with prominence of the face ipsilaterally to the cerebral hemiatrophy, right hemierythroderma, secondarily generalized focal seizures, slight regression in speech and walking. And so, Kiza designates the name of the patient and Ntenga which designates the name of the author who described him.

Published: March 2023

Kilovoltage (kV) radiotherapy, also called superficial radiotherapy (SXT) or orthovoltage radiotherapy (DXT), is a well-known and effective treatment option for non-melanoma skin cancer and some benign skin and musculoskeletal conditions. Given its surface dose delivery, its use in radiation oncology beyond superficial skin cancers is generally limited, but it has also been shown to be extremely useful for specific palliative applications. Here, we describe the characteristics of kilovoltage radiotherapy and report on six cases of locally advanced and/or metastatic breast cancer in which kilovoltage radiotherapy was used as the primary modality or as supportive treatment to linac-based radiotherapy to gain local tumor control and improve the patient’s quality of life.

Shortest paths of Rubik’s Snake prime knots up to 5 crossings
Authors: Hou Songming , Su Jianning
Published: March 2023

A Rubik’s Snake is a toy that was invented over 40 years ago together with the more famous Rubik’s Cube. It can be twisted into many interesting shapes including knots. Four blocks can form a trivial knot. In this paper, we study how many blocks are needed to form a nontrivial knot with up to 5 crossings. The results are classified using the DT (Dowker-Thistlethwaite) code to make sure each design is indeed the knot we claimed it is. A line representation is used to clearly reveal the knot structure of the Rubik’s Snake. Exhaustive local searches are performed to verify that no local improvement is possible for the shortest paths we found.
Linearization of feedback controller robust to the presence of uncertainties for a wheeled robot with a trailer

Published: March 2023

The wheeled mobile robot with differential thrust consists of two independent active wheels and a passive spherical wheel. Assuming its net rolling and non-uncertainty, this robot is a nonlinear system bound to non-holonomic constraints. This system also falls into the category of systems with a lack of operators. Tracing time travel paths is one of the most difficult issues in the field of wheeled robots that we will address in this article. In this regard, first the kinematic model of the system with the presence of uncertainty on the control inputs is expressed in which the linear velocity and angular velocity of the robot are considered system inputs. After determining the desired reference paths, using the linearization of the designed feedback controller ensures the stability of all system state variables globally. The controller is then designed with adaptive rules to solve the problem of tracking time paths based on input-output control in the presence of uncertainties. The stability of this controller is also proven globally. Finally, the performance of the designed controllers to compensate for the uncertainties will be compared by comparing the results.
The corrected mathematical models for the top motion
Authors: Usubamatov Ryspek , Kapayeva Sarken
Published: March 2023

The mathematical models for the top motions in known publications contain the incorrect expression of the centrifugal torque and do not consider the action of the Coriolis torque generated by the center mass. In reality, the two centrifugal torques, two torques of Coriolis forces, and two changes in the angular momentums formulate the dependency of the angular velocities of the top motions about two axes. The corrected expression of the centrifugal torque and the Coriolis torque generated by the center mass changed the mathematical models for the top motion and its self-stabilization. The new analytical approach for the spinning top motions with the action of all external and inertial torques gives an accurate solution and describes its physics. The derived mathematical models for the spinning top motions and solution represent a good example of the educational process of engineering mechanics.
Quality of service provisioning to deliver scalable high efficiency video coding (SHVC) over SDN networks

Nowadays, Internet traffic is dominated by video streaming and delivering these services is a challenging task. Providing end-to-end Quality of Service (QoS), and consequently providing an adequate Quality of Experience (QoE), is essential in the multimedia industry. In this paper, we designed LSDN, an effective SDN-based solution that leverages SDN and SHVC video codec feature to provide a reliable video streaming mechanism. LSDN uses the ability of SDN to dynamically update forwarding tables of routers and switches and transfer different video layers of SHVC over distinct network paths. To evaluate the performance of LSDN, we emulated LSDN over Mininet. Our experimental results show that LSDN significantly improves the performance of delivering high-quality videos in terms of deduction in delay, loss, and jitter. Moreover, we observed that LSDN does not have negative effects on the background traffic.
Affectation index and severity degree by COVID-19 in Chest X-ray images using artificial intelligence

Published: March 2023

The Covid-19 pandemic has caused the congestion of intensive therapies making it impossible for each to have a full-time radiology service. An indicator is necessary to allow intensivists to evaluate the evolution of patients in advanced state of the disease depending on the degree of involvement of their lungs and their severity in chest X-ray images (CXR). We propose an algorithm to grade the affectation of lungs in CXR images in patients diagnosed with COVID-19 in advanced state of the disease. The algorithm combines the assessment of image quality, digital image processing and deep learning for segmentation of the lung tissues and their classification. The proposed segmentation method is capable of dealing with the problem of diffuse lung borders in CXR images of patients with COVID-19 severe or critical. The calculation of the affectation index (IAF) consists of the classification of the segmented image by establishing the relationship between the number of pixels of each class. The IAF index of lung affectation in CXR images and the algorithm for its calculation. A correlation was established between the IAF and the international classification of the degree of severity established by radiologists.

Published: March 2023

The use of voice-operated robots in real-life settings introduces multiple issues as opposed to the use of them in controlled, laboratory conditions. In our study, we introduced conversation robots in the homes of 18 older adults’ homes to increase the conversation activities of the participants. A manual examination of the audio data the robot considered a human voice showed that a considerable amount was from television sounds present in the participants’ homes. We used this data to train a neural network that can differentiate between human speech and speech-like sounds from television, achieving high metrics. We extended our analysis into how the voices of the participants contain inherent patterns that can be general or uncommon and how this affects performance of our algorithm in our attempts to identify human speech with or without these patterns.
Computer controlled image based object classification by using a robot manipulator
Authors: Uyar Erol , Candan Mücahid
Published: March 2023

In this paper the design, implementation and application of a computer controlled vision system with a robot manipulator for classification of various fruits is introduced. The system, which consists of a RGB Camera, a PC and a five degree of freedom (DOF) robot manipulator, specifically set up to work in real-time applications. At the first stage of study the captured image of objects in RGB scale viewed by the camera is stored via USB link of computer as digital image data in registries for further segmentation process to recognize the objects. A particular Neural Network is designed to classify objects exactly. The moving objects on a belt, driven by a servo-stepper motor, are recognized in size and property via a vertically mounted camera. The recognized objects are then assorted by a computer controlled robot manipulator with five DOF and a gripper at the end-effecter, in order to transport the objects via a predefined trajectory to designated locations. As second stage, the kinematic link table of robot manipulator using inverse kinematics is determined, so that from the given way points of a particular trajectory the link parameters (joint angles) can be calculated. The joint angles are used as reference values for a joint based control algorithm programmed in C++. The joints are equipped with geared DC motors with position feedback. A particular control program is also used to control the motion of servo-stepper belt motor and the pneumatically activated gripper valve of the manipulator. Successful results are evaluated both in assorting of fruit in size, property, in synchronous working of the robot arm and in connection with image processing.
