Adaptation of Cardinal Points Symmetry Landmarks Distribution Model to in-vivo B-Mode Ultrasound Images of Transverse Cross-section of Carotid Arteries
Authors: Udekwe Charles Nnamdi , Ponnle Akinlolu Adediran
Published: February 2022

The geometry of the imaged transverse cross-section of carotid arteries in in-vivo B-mode ultrasound images are most times irregular, unsymmetrical, full of speckles and usually non-uniform. We had earlier developed a technique of cardinal point symmetry landmark distribution model (CPS-LDM) to completely characterize the Region of Interest (ROI) of the geometric shape of thick-walled simulated B-mode ultrasound images of carotid artery imaged in the transverse plane, but this was based on the symmetric property of the image. In this paper, this developed technique was applied to completely characterize the region of interest of the geometric shape of in-vivo B-mode ultrasound images of non-uniform carotid artery imaged in the transverse plane. In order to adapt the CPS-LD Model to the in-vivo carotid artery images, the single VS-VS vertical symmetry line common to the four ROIs of the symmetric image is replaced with each ROI having its own VS-VS vertical symmetry line. This adjustment enables the in-vivo carotid artery images possess symmetric properties, hence, ensuring that all mathematical operations of the CPS-LD Model are conveniently applied to them. This adaptability was observed to work well in segmenting the in-vivo carotid artery images. This paper shows the adaptive ability of the developed CPS-LD Model to successfully annotate and segment in-vivo B-mode ultrasound images of carotid arteries in the transverse cross-sectional plane either they are symmetrical or unsymmetrical.
Effects of Inclination angle and Free Convection on Velocity Profile for a Steady 2-Dimensional Magnetohydrodynamic Fluid Flow in an Inclined Cylindrical Pipe
Authors: Odongo B. , Opiyo R. , Manyonge A.
Published: February 2022

Effects of inclination and free convection on velocity profile for magnetohydrodynamic (MHD) fluid flow in an inclined cylindrical pipe has been investigated. The governing partial differential equations are the equations of continuity, momentum and energy which are converted into ordinary differential equation by employing similarity transformation and solved numerically by the Runge- Kutta fourth order scheme with shooting method. The findings, which are presented in the form of tables and graphs reveal that; when Hartmann number, Grashoff number and Gamma are decreased, the velocity of the fluid increases. The results of the study may be useful for the different model investigations, especially, in various areas of science and technology in which optimal inclination and free convection are utilized.

Published: February 2022

The fear from the continuous spreading of the Covid-19 pandemic had put lot of restrictions on the movement of goods around the world. In Egypt, the importing of goods especially electronic products from many countries including China was crucial to the research and educational purposes. The restrictions had stopped the importing of many electronic devices from China including cameras. Object detection and identification were among the hot topics of research in our university which depended mainly on imported cameras. In this paper we tackle the problem of setting up stereo cameras using old non identical cameras to do object detection. The selection of the cameras was not optional since we had to use what we found in our old laptops. OpenCV and Python programming commands were used to set the two cameras to obtain equally clear images as much as possible. A disparity map was then calculated using openCV and its accuracy was then discussed. Accuracy was dependable on the sharpness of the cameras used, Gamma parameter, number of pixels per image and matching algorithm to match the two images obtained using the stereo cameras.

Published: February 2022

Heat exchange mechanisms involved in the conversion of solar energy to heat were determined using a parabolic trough collector. This study's goal is to examine the impact of operational and environmental factors on the energetic, performance of three different Parabolic Trough Collector receivers used to generate hot water. The collectors used uncoated, grey, and black receiver tubes. The parabolic trough concentrator is built of mild steel as the mainframe support with a segmented mirror reflector. Reflectivity is 0.85, rim angle is 90, an aperture area is 2.42 m2, and concentration ratio is 11.7. The parabolic trough concentrator's focal point has galvanized iron receiving tubes. The receiver tubes were fitted individually via the parabolic reflector's focal point. The thermal exergy of each absorber tube was determined while water flowed at 0.003 kg/s. During the investigation, solar radiation, and water temperatures at the absorber tube's input and outflow were all measured. The results show that both the temperature of the heat transfer fluid and the amount of solar radiation have a substantial effect on thermal energetic performance. This concentrator reduces dependency on electric power while minimizing fossil-fuel emissions, reducing pollution.

Authors: Cristina Moreira Damázio Laila
Published: February 2022

Introdução: A ventilação mecânica (VM) é utilizada para auxiliar na ventilação de um paciente crítico em diversas situações clínicas, porém, o manejo incorreto está associado as Lesões Pulmonares Induzidas pelo Ventilador (LPIV), principalmente quando se trata de paciente com comprometimento pulmonar. A Síndrome do Desconforto Respiratório Agudo (SDRA) é uma condição que tem seu tratamento diretamente relacionado a VM, uma vez que o ventilador mecânico reduz o desconforto respiratório.  Estratégias de VM protetora vêm sendo utilizadas devido aumento da taxa de sobrevida, e tais estratégias visam ao Volume Corrente (VC) com números menores e PEEP elevadas evitando o colapso alveolar e reduzindo as tensões em tecidos pulmonares prevenindo as lesões induzidas por um manejo incorreto da VM. Objetivo: Investigar a relação entre o monitoramento da mecânica pulmonar durante a utilização da ventilação mecânica e a ocorrência de lesão pulmonar induzida pela ventilação. Métodos: Revisão sistemática utilizando as bases de dados da Biblioteca Virtual de Saúde, MEDLINE, Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS). Os descritores foram: “ventilação mecânica”, “lesão pulmonar induzida por ventilação mecânica”, “mecânica respiratória”. Foi utilizado o operador boleano “AND”, selecionados artigos nas línguas portuguesas, inglesas e espanhol nos últimos 10 anos. Conclusão: Para um bom prognóstico, é necessário o reconhecimento da condição pulmonar, a interação multidisciplinar, o conhecimento das condições clínicas da patologia e o manejo correto dos parâmetros ventilatórios. A VM protetora se mostrou benéfica afim de evitar as LPIV, preconizando VC baixo e monitorização da DP.

Published: February 2022

Ankle fractures management in old individuals has been discussed controversially. We aimed to assess clinical outcomes in patients undergoing surgery and those receiving non-surgical treatment. MEDLINE, PubMed, EMBASE, Google Scholar, and Cochrane databases were searched in June 2019. In the synthesized analyses, patients above 50 years of age who received surgical treatment through open reduction and internal fixation (ORIF) were compared to those who underwent non-surgical treatment through closed reduction and casting for relevant clinical outcome parameters. We identified 12 eligible studies with a total of 54,699 patients. Of these, 27,110 received surgical and 27,588 non-surgical treatment. Surgical treatment was associated with a lower risk of non-unions (odds ratio [OR]: 0.127; 95% confidence interval [CI]: 0.055, 0.292, P < 0.001) as well as mal-unions (OR: 0.128, 95% CI: [0.063, 0.262], [P < 0.001]), and mortality at 1-year post-treatment (OR: 0.509, 95% CI: [0.266, 0.975], [P = 0.042]). Similarly, the duration of return to pre-injury activity was significantly shorter in a surgical group whereas skin complications were associated with a higher risk in the surgical group (OR: 4.923, 95% CI: [3.720, 6.515], [P < 0.001]). Neither rates of satisfaction and re-admission nor duration of hospital stay and period in cast differed between surgical and non-surgical treatment groups. In patients above the age of 50 years, ORIF seems to be superior to non-surgical treatment for relevant clinical outcomes such as non-union, mal-union, and mortality rates; as well as return to pre-injury level was better in the surgical group.
Percutaneous fixation for the treatment of metastatic spinal disease provides effective symptom palliation with low rates of hardware failure
Authors: Jaman Emade , Zhang Xiaoran , Allen Jordan , Saraiya Raj G. , Tollefson Savannah , Hamilton D. Kojo , Amankulor Nduka M.
Published: February 2022

Background:

The incidence of survival from metastatic spinal disease (MSD) continues to rise. However, open surgery for MSD is associated with significant perioperative morbidity, while minimally invasive percutaneous pedicle screw fixation (MIPPSF) offers reduced tissue trauma, less blood loss, and a reduction in complications. Lytic bone disease plus perioperative radiation further increase risk for instrument failure, especially in long construct MIPPSF. Here, we compared 6 short construct and 14 long construct outcomes for MIPPSF performed in MSD patients, including multiple myeloma (MM).

Methods:

For 20 patients undergoing MIPPSF for MSD, we evaluated disease type, location, the extent of surgery, outcomes, and survival rates. Statistical comparisons were performed between long-segment construct and short-segment construct patients utilizing Kaplan–Meier survival curves, Mann–Whitney U, and Chi-squared tests.

Results:

No instrument failure and comparable symptomatic relief were observed for both short and long MIPPSF constructs. However, long construct patients experienced; a higher incidence of postoperative complications, including screw loosening, but exhibited longer overall survivals (likely related to underlying type of MSD, with MM patients making up the largest portion of long construct patients).

Conclusion:

Long construct MIPPSF in MSD did not have increased risk of construct failure and offered effective symptomatic relief, including for MM patients, without introducing a greater risk construct instability.

This research focuses on the optimization of production of bio-fertilizer from watermelon peels. Central Composite Design (CCD) under the Response Surface Methodology (RSM) of the Design Expert software version 6.0 was used to optimize the retention days and water ratio, (factors), while Nitrogen(N), Phosphorous (P) and potassium (K) were the responses. Watermelon peel was blended and fermented for different days based on the experimental design obtained. The optimum values obtained after optimization for retention days and water ratio are 20 days and 400 ml respectively, while N. P and K contents are 26.2824, 94.5099 and 0.0005, respectively. The use of Bio-fertilizer will be more economical and safer for farming activities.
Quantitative reversible one pot interconversion of three crystalline polymorphs by ball mill grinding.
Authors: Belenguer Ana M. , Lampronti Giulio I. , Michalchuk Adam A. L. , Emmerling Franziska , Sanders Jeremy K. M.
Published: February 2022

We demonstrate here using a disulfide system the first example of reversible, selective and quantitative transformation between three crystalline polymorphs by ball mill grinding. This includes the discovery of a previously unknown polymorph. Each polymorph is reproducibly obtained under well-defined neat or liquid-assisted grinding conditions, revealing subtle control over the apparent thermodynamic stability. We discovered that presence of a contaminant as low as 1.5% mol mol-1 acting as a template is required to enable all these three polymorph transformations. The relative stabilities of the polymorphs are determined by the sizes of the nanocrystals produced under different conditions and by surface interactions with small amounts of added solvent. For the first time, we show evidence that each of the three polymorphs is obtained with a unique and reproducible crystalline size. This mechanochemical approach gives access to bulk quantities of metastable polymorphs that are inaccessible through recrystallisation.
Two Paths to Oxidative C−H Amination Under Basic Conditions: A Theoretical Case Study Reveals Hidden Opportunities Provided by Electron Upconversion
Authors: Eckhardt Paul , Elliott Quintin , Alabugin Igor , Opatz Till
Published: February 2022

Traditionally, cross-dehydrogenative coupling (CDC) leads to C−N bond formation under basic and oxidative conditions and is proposed to proceed via a two-electron bond formation mediated by carbenium ions. However, the formation of such high-energy intermediates is only possible in the presence of strong oxidants, which may lead to undesired side reactions and poor functional group tolerance. Alternatively, oxidation under basic conditions allows the formation of three-electron bonds. In a three-electron bond, two electrons will occupy a bonding orbital and the third is forced into a high energy anti-bonding orbital (resulting in an “upconverted” highly-reducing species). The benefit of this “electron upconversion” process is in the ability to use milder oxidants (e.g., O2) and to avoid high-energy carbenium ion intermediates. To explore the scope of this approach, we directly compared two- and three-electron pathways using quantum mechanical calculations. We observed that the absence of a strong oxidant can shut down two-electron pathways in favor of a three-electron path. Additionally, we investigated key factors involved in the three-electron C−N bond formation by analyzing the cyclization of 42 radical anions. An interesting stereoelectronic feature for the reaction of highly stabilized diester anions is that only one of the ester groups is involved in the extra electron delocalization in the cyclized radical anion product. Hence, the effect of unproductive reactant stabilization can be removed in the cyclizations of monoester enolates rendering such reactions much more thermodynamically favorable.

It was found that more often the disease was accompanied by complaints characteristic of asthenic syndrome, fever and cough. The main clinical forms of the disease were acute viral infection and pneumonia without respiratory failure of moderate severity. In most children, the infection proceeded without damage to the lung tissue or with minimal damage to the lung parenchyma. A more severe course of infection with the development of respiratory failure was noted in schoolchildren and adolescents. In 42.9% of children were revealed multimorbid conditions. The most common conditions were iron deficiency anemia and autonomic dysfunction. The most severe course of infection was noted in children with hematological malignancies. In laboratory tests, children showed leukopenia, an increase of ferritin and activation of thrombus formation. 51.4% children were discharged in 1114 days of the disease. Deaths were in 1.9% of patients with leukemia.

Depending on the time and conditions of infection, neonatal pneumonia is divided into intrauterine and postnatal, which can be community-acquired, nosocomial, ventilator-associated, aspiration. Congenital pneumonia, which is difficult to distinguish from the respiratory distress syndrome of newborns is a component of generalized infection of the fetus and newborn. According to the time of clinical manifestations, neonatal pneumonia is divided into early (the first week of life) and late (828 days of life). The etiology of pneumonia in newborns depends on the time, path and conditions of infection. The diagnosis of pneumonia in newborns is determined by the level and equipment of the clinic and is based on the determination of antenatal and postnatal risk factors, respiratory and general symptoms, radiological signs, markers of the systemic inflammatory reaction/bacterial infection syndrome and the results of etiological diagnosis. The deterioration of the newborn's condition on a ventilator can be associated not only with ventilator-associated, but also with other fan-associated events (fan-associated condition; ventilator is an associated event in children receiving antimicrobials), the causes of which may be pulmonary edema, atelectasis, acute respiratory distress syndrome, recent surgical procedures, sepsis, the formation of bronchopulmonary dysplasia. For the initial therapy of early neonatal pneumonia, a combination of ampicillin with gentamicin is used. In case of late neonatal pneumonia that occurred in a hospital, primary therapy should necessarily include anti-pseudomonas and anti-staphylococcal antibiotics. For community-acquired pneumonia in newborns, antibiotics acting on gram-negative bacteria (inhibitor-protected beta-lactams, cephalosporins of the third generation, aminoglycosides) are prescribed.

Nasal breathing disturbance in young children is a serious problem, since the anatomical features of the structure of the nasal cavity and nasopharynx in young children can become a background for the development of complications. Regardless of the form of rhinitis, the leading symptoms are nasal congestion and rhinorrhea. Many over-the-counter drugs are used to relieve rhinitis symptoms, but the vast majority of these drugs are contraindicated for babies. Among the safe and effective drugs that eliminate the main symptoms of rhinitis, the topical decongestant spray Otrivin For children and the nasal aspirator Otrivin Baby with drops for irrigation of the nasal cavity are used. These products are specially designed for children in the first years of life, have a high safety profile and effectively eliminate nasal congestion and discharge, quickly restoring the well-being of the youngest patients.

The study was quantitative and explanatory in nature. The population comprised all the teaching and non-teaching staff of the institution. A Simple Random Sampling techniques was used for selecting the sample from the population. Primary data was collected by administering questionnaires to the teaching and non-teaching faculty members of the school. Data was analyzed using frequencies, mean, standard deviation, one sample t-test and a multiple linear regression. After the analysis, it was found that the interpersonal justice aspect of performance appraisal fairness had a significant effect on employee performance. Staff were indifferent with performance appraisal systems, but according to management, frequently undertaken performance appraisal helps to recognize individual training and developmental needs. For this reason, performance appraisal is undertaken to examine and evaluate the performance of staff of Kumasi Technical University. One key challenge performance appraisal as identified from the management perspective indicated that the assessment of employees does not translate into an enhanced performance management. As part of employee performance, the staff agreed to possess increase knowledge on job, work with little supervision, improved skills due to new learning methods, and committed to work due to new skills acquired.

The purpose of the monograph, which contains a modern view of the problem of adaptation of children with extremely low body weight, is to provide a wide range of doctors with basic information about the clinical picture, functional activity of innate and adaptive immunity, prognostic criteria of postnatal pathology, based on their own research. The specific features of the immunological reactivity of premature infants of various gestational ages who have developed bronchopulmonary dysplasia (BPD) and retinopathy of newborns (RN) from the moment of birth and after reaching postconceptional age (37-40 weeks) are described separately. The mechanisms of their implementation with the participation of factors of innate and adaptive immunity are considered in detail. Methods for early prediction of BPD and RN with the determination of an integral indicator and an algorithm for the management of premature infants with a high risk of postnatal complications at the stage of early rehabilitation are proposed. The information provided makes it possible to personify the treatment, preventive and rehabilitation measures in premature babies. The monograph is intended for obstetricians-gynecologists, neonatologists, pediatricians, allergists-immunologists, doctors of other specialties, residents, students of the system of continuing medical education. This work was done with financial support from the Ministry of Education and Science, grant of the President of the Russian Federation No. MK-1140.2020.7.
Dialektika Konsep Ketuhanan dalam Ritual Lea sose pada Masyarakat Manggarai dan Gereja Katolik
Authors: Juhani Sefrianus , Denar Benediktus , Riyanto FX. E. Armada
Published: February 2022

This article aims to dialogue the concept of divinity in Manggarai, Indonesia, with the teachings of the Catholic Church. The concept of God in the Manggarai community has some similarities with the doctrine of God in the Catholic Church, that is, concerning the acknowledgment of God’s existence, involvement, and care. However, there are also matters that are quite different and that are not found in each respective context. On the one hand, the similarities can help those involved in catechesis with fresh understandings. On the other hand, the differences may enrich the outlook into knowledge about the concept of divinity, both in the context of living the Church’s teachings as well as in the context of being member of the cultural community. The results of the dialogue as explored in this article open the possibilities to help decrease the practices of syncretism on matters of faith in the Manggarai Catholic community. The approaches used by the authors to trace the concept of divinity in the two contexts are mainly qualitative with ethnographic and documentation methods. The findings are a mainstay for pastoral agents in determining certain themes for catechesis, especially those related to the concept of Godhead.

Published: February 2022

This paper discusses about application of dissipative concept in dynamical systems for analysis and synthesis of control systems via linear matrix inegualities (LMIs). Motivated by dissipativity concept in mechanical and electrical circuit system, one could employ this concept to check stability and to design a controller of the underlying system. We derive the solvability condition of dissipativity for an output feedback LTI continuous system via LMIs. An algorithm to design such controller that satisfy the dissipativity of the system is also considered.

Generally, earthquake resistant design is based on elastic structural analysis with load factor to simulate ultimate condition. Actually, behavior of collapse structures during earthquake is in-elastic. Evaluation to predict in-elastic condition of structures during earthquake is needed in order to guarantee that it can perform well during earthquake. Analysis and performance evaluation can be done with pushover analysis given in SAP2000, while evaluation of performance point must be determined manually with various methods (except for capacity spectrum method). Pushover analysis is a non linear static analysis as a behavior of structural failure due to earthquake, while performance point is structural maximum displacement during design earthquake.

Study on steel frame 3D concludes that performance evaluation for pushover in longitudinal direction according to ATC-40 gives displacement target for moment frame building of 0.054 m, building with eccentrically braced frame (EBF): 0.022 m. Pushover in transverse direction according to ATC-40 gives displacement target for moment frame building of 0.022 m, building with EBF: 0.015 m. According to FEMA 356, displacement target in longitudinal direction for moment frame building: 0.0803 m, building with (EBF): 0.0728 m. For building with moment frame in transverse direction: 0.1183 m, building with (EBF): 0.0614 m.
