Polyvinylidene Fluoride (PVDF) / Poly (Ether Sulfones) (PES) Blend Membrane For CO2/CH4 Separation
Authors: Ramzi Q , Abd Rahman Sunarti , Bijarimi Mohd , Alhadadi Waleed 
Published: June 2023

In this study, a combination of Polyvinylidene fluoride (PVDF) and Poly (ether sulfones) (PES) blend membrane and DMF as solvent component was developed to evaluate the CO2 and CH4 separation performance. The gas permeation test was thereafter conducted on the membrane produced. The separation through a membrane works on the theory of permeation based on permeability and selectivity. These two important values were estimated using a set of analytical functions. The membranes produced was then characterized using scanning electron microscopy (SEM) and the Fourier Transform Infrared Spectroscopy (FTIR). The result obtained revealed that a higher permeability for the CO2 and CH4 gases when the blending ratio of membrane and solvent of PVDF:PES:DMF/ 5:15:80 were applied. Moreover, the selectivity results showed that the use of the blending ratio of PVDF:PES:DMF/ 20:0:80 produce the highest selectivity (1.3086 GPU) while blending ratio of PVDF:PES:DMF/ 10:10:80 exhibited the least selectivity. In addition, the morphological elucidation revealed the presence of pores for every cross-section composite membrane and this aids the permeability properties of the membrane aggregates at different blending ratio. Also, the FTIR results showed nearly similar functional group characteristics.

In this research, a new dryer which use halogen lamp must be designed and the drying performance of Roselle is to be investigate. The power of lamp is varied (50, 75, 100, 125, 150, 175, 200, 225) W. The result shows that higher power of lamp produce high temperature and low humidity which shorten the drying time of Roselle. The drying rate of each parameter shows slightly different pattern as temperature does not constant since the power supply does not produce constant voltage or current. The heat of vaporization increase as the power of lamp is increase and quantity of heat energy to raise temperature of Roselle at certain mass also increase. The most suitable parameter is 200W since the colour of Roselle does not degrade very much with short drying time 240mins, heat, transfer coefficient 91.51 W/2K . Maximum has a sour taste and is ordinarily utilized in the readiness of cold and hot drinks and as energy needed to heat Roselle at 62⁰C is 17.02 kJ and heat of vaporization are determined to be 2612.3 kJ/kg.
Le Mouvement du 20 février au Rif. Mémoire de violence et réconciliation politique
Authors: Nahhass Badiha , Rhani Zakaria 
Published: June 2023

Le mouvement du 20 février (M20F), survenu en 2011, est la version marocaine de ce qu’a été nommé par les observateurs « Printemps arabe ». Le M20F a connu des articulations différentes d’une région à l’autre. Des spécificités qui sont surtout liées aux particularités politico-historiques et socioéconomiques. Cet article propose d’analyser les dynamiques protestataires dans la région du Rif, Al Hoceima en particulier. Nous arguons que ces dynamiques, tout en s’inscrivant en continuité avec le mouvement M20F global, présentent des spécificités liées à l’histoire de cette région, notamment des rapports singuliers à l’histoire des mouvements de protestation postindépendance, marqués par la violence, et leurs mémoires incorporées.

Published: June 2023

HighlightsThe development and implementation of video-assisted thoracoscopic atrial fibrillation ablation since 2005 by R. Wolf and colleagues have undergone a number of modifications for improvement and simplification. A study of the evolutionary development of thoracoscopic ablation of atrial fibrillation is necessary to optimize ablation recruitment and surgical technique for different forms of atrial fibrillation. AbstractThere is a variety of treatments for atrial fibrillation (AF): therapeutic, interventional and surgical. The effectiveness of these methods varies significantly depending on the form of AF. For a long time, surgery was considered the only highly effective treatment for AF. In modern arrhythmology, «Maze IV» and its modifications are considered only as a simultaneous procedure in cardiac surgery. The work of M. Haïssaguerre et al. has established that the main focus of catheter ablation (CA) in AF should be the pulmonary veins, but their isolation in non-paroxysmal AF is questionable. This discovery has stimulated the development of alternative treatment modalities for resistant AF. Recently, video-assisted thoracoscopic epicardial ablation (TSA), which does not require sternotomy, cardiopulmonary bypass and cardioplegia, has been increasingly preferred. TSA of AF is an alternative surgical treatment for isolated forms of AF on the working heart. This procedure may include: pulmonary vein ablation, posterior left atrial wall and pulmonary vein ablation and left atrial appendage exclusion, but its effectiveness varies considerably due to the heterogeneity of patients, surgical technique and follow-up period. The aim of this review is to provide data on the evolutionary development of thoracoscopic ablation of AF depending on the choice of surgical access, ablation line set and ablation device.

HighlightsThe present study was conducted to evaluate in-hospital outcomes of one of the most effective and simultaneously controversial surgical techniques for myocardial revascularization using two internal thoracic arteries (ITA).To this date, this is the most complete analysis that has been carried out at the Research Institute on the topic of studying bilateral internal thoracic artery grafting (BITA). The results obtained are of great importance for the subsequent evaluation of long-term results. AbstractAim. To analyze in-hospital outcomes of BITA.Methods. The study included 232 patients who were admitted to the Cardiac Surgery Department for coronary artery bypass grafting (CABG). All patients were divided into 2 groups depending on the use of either single or bilateral ITA conduits. Both groups included equal number of patients – 116. In-hospital outcomes were analyzed.Results. BITA and CABG with single ITA were proven to be comparable regarding myocardial infarction, stroke, the need for percutaneous coronary intervention, death, and composite endpoint. At the same time BITA patients significantly more often had longer hospital stay and required inotropic drugs.Conclusion. BITA is a safe procedure comparable to classic CABG in terms of in-hospital complications, but at the same time, this intervention is associated with longer hospital stay, and extended inotropic drugs use.

HighlightsThe article describes a rare case of surgical treatment of pulmonary artery intimal sarcoma. The authors analyzed the causes for incorrect diagnosis of pulmonary embolism in detail, and proposed alternative options for distinguishing the diseases under consideration. Moreover, the authors analyzed different surgical treatment modalities of intracardial sarcomas, and demonstrated the prospect of using molecular hydrogen as a component of an anesthetics during surgical interventions with cardiopulmonary bypass. AbstractThe article describes a rare clinical case of a patient with pulmonary artery sarcoma. The absence of specific symptoms of sarcoma, as well as features of developing cardiovascular and respiratory failure, characteristic of pulmonary embolism, contributed to the incorrect diagnosis. The article analyzes the main problems of primary diagnostics, and proposes new parameters for evaluating manifesting symptoms and the results of additional examination, which should improve the results of surgical treatment of malignant tumors.

Authors: Klyshnikov Kirill Yu. , Ovcharenko Evgeny A. , Barbarash Leonid S. 
Published: June 2023

HighlightsThe «TiAra» bioprosthetic heart valves have better hemodynamic characteristics, such as higher effective orifice area and a lower mean pressure gradient.The «UniLine» bioprosthetic heart valve demonstrated better closing dynamic, expressed in a smaller regurgitation volume. Aim. To assess hydrodynamic characteristics of the «TiAra» bioprosthetic heart valve with flexible supporting frame compared with the classic stented «UniLine» bioprosthetic aortic valve.Methods. Using the Vivitro Pulse Duplicator (Vivitro Labs, Canada), we simulated the function of the heart via generating pulsatile flow to analyze bioprosthetic heart valves. To comprehensively assess the bioprosthesis function, three valves of each standard size (21, 23, 25 mm) were submitted to hydrodynamic testing, thus making a sample of nine bioprostheses of each model. The article provides the analysis of the effective orifice area, mean pressure gradient, regurgitation volume, and assessment of the statistical sensitivity of the parameters between groups at p = 0.05.Results. The assessment revealed that the «TiAra» bioprosthesis has bigger effective orifice area (p = 0.006) and lower mean pressure gradient (p = 0.02): 1.6–2.2 cm2 and 3.6–6.3 mmHg versus 1.08–1.73 cm2 and 4.8–12.1 mmHg, respectively. The regurgitation volume, however, was lower in the «UniLine» bioprostheses 0.8–4.1 mL/cycle versus 6.2–9.0 mL/cycle (p = 0.0004).Conclusion. Despite the fact that both studied models showed good hydrodynamic performance, the prosthesis with the flexible supporting frame («TiAra») showed better results regarding its effectiveness in vitro via presenting with bigger effective orifice area and lower mean pressure gradient. At the same time, the «UniLine» stented bioprosthesis had lower regurgitation volume, i.e. better closing dynamics.

Published: June 2023

Background: Functional constipation (FC) is a common pediatric problem worldwide. The management of FC comprises of a short initial disimpaction phase followed by long-term maintenance phase. Currently, polyethylene glycol (PEG) is considered as standard disimpaction therapy in pediatric FC patients. The aim of our study was to compare the efficacy of polyethylene glycol 3350 monotherapy with polyethylene glycol 3350 and sodium picosulfate combined therapy in treating fecal impaction in pediatric FC patients.
Methods: All children (aged >1 year) diagnosed with FC as per ROME IV criteria and presenting to the out-patient department of pediatric gastroenterology, hepatology and nutrition unit of a tertiary health centre in north Indian Himalayan state were randomized into two open label, prospective, parallel groups, namely group A (receiving PEG 3350 monotherapy) and group B (receiving combined PEG 3350 plus sodium picosulfate therapy), over a period of 13 months. The outcome was evaluated as successful disimpaction with onset of loose/watery stools (Type-7 of Bristol stool chart scale). The success rates and mean time to disimpaction for two groups were computed and compared.
Results: Eighty-one patients were randomized into two groups. The mean time to disimpaction was found to be significantly lower (p<0.001) for group B (2.37±1.16 days) when compared to group A (4.00±1.43 days). There was successful resolution of impaction in both groups. No adverse events were reported in either group.
Conclusions: Combined PEG 3350 and sodium picosulfate therapy significantly reduces the disimpaction time when compared with PEG 3350 monotherapy in pediatric population, however both the therapies appear similar in achieving successful disimpaction.
