Abstract Introduction Complications following Cardiopulmonary resuscitation (CPR) are rare and usually follows a vigorous CPR or in special cases like pregnancy are due to lack of knowledge and clinical practice of how to preform CPR in pregnancy. One of this complication is diaphragmatic rupture with herniation of abdominal organs. Surgical intervention needs to be planned carefully in multidisciplinary team approach and requires fine surgical techniques for better outcome. There are few reported cases of diaphragmatic rupture after Cardiopulmonary resuscitation but none in pregnant woman. Case presentation We report a rare case of diaphragmatic rupture in a 29-year-old pregnant patient who experienced a full-blown diaphragmatic defect and herniation of the abdominal organs into the thoracic cavity, as a complication of CPR. Following careful assessment and diagnosis, the patient underwent urgent laparotomy with reduction of the contents and primary closure of the defect. One year follow up was satisfactory. To the best of our knowledge, this is the first reported case of diaphragmatic rupture with herniation of the abdominal organs following CPR in a pregnant woman in the literature. Conclusion The application of external cardiac massage through CPR is a life-saving procedure for the management of cardiac arrest. Common complications related to CPR include rib fractures, sternal fractures and haemothorax. Diaphragmatic rupture with herniation of the abdominal organs is a rare complication, having been reported only once in the literature (Sabzi F, Faraji R, Tanaffos 16:170–172, 2017); however, it represents a serious and life-threating event. Thus, careful evaluation of the patient by a multidisciplinary team and prompt intervention is recommended in order to improve outcomes.

Purpose:: It is imperative to spare functioning kidneys from high radiation doses when they are near enough to radiotherapy (RT) target volumes in patients with polycystic kidney disease (PKD). To achieve this intent, we designed the unique approach that we report here. Methods and materials:: The patient who has PKD, presented with B-cell lymphoma involving paraaortic lymph nodes. After completing chemotherapy, RT was planned to the residual nodal disease. The diagnostic positron emission tomography computed tomography (PETCT) scan was fused with the RT planning CT scan. 18F-2-deoxy-2(F)-fluro-d-glucose (FDG) avid active kidneys were contoured separately, and the treatment plan was optimized to avoid these volumes. Results:: The functional volume was 17.52% of the right kidney whereas it was 7.44% of the left. The mean doses were 4.61 Gy and 4.2 Gy, respectively. The baseline estimated glomerular filtration rate (eGFR) was >60 mL/min; at 18 months follow-up, it was 62 mL/min. Conclusions:: Delineation of functional nephrons was feasible while utilizing the staging FDG-PETCT scan for radiotherapy contouring in our patient, which aided to achieve the optimal dose-volume constraints. Further studies are warranted to analyze and quantify the benefit of this easily accessible method in the future.

The removal of nitrate and phosphate ions from wastewater has a major concern nowadays. It is necessary to remove nitrate and phosphate ions from wastewater. Adsorption becomes a promising method for phosphate and nitrate ions removal from wastewater because of their availability, low cost, stability and high adsorption capacity. Fume Dust from an Electric Arc Furnace is an industrial waste produced from El-Masryeen Steel factory which is used as an adsorbent for simultaneous removal of nitrate and phosphate ions from an aqueous solution. Surface characterization is performed for the Fume Dust from an Electric Arc Furnace waste before and after adsorption process to ensure nitrate and phosphate ions adsorption and to predict the adsorption mechanisms for each of them. The effects of changing pH, initial nitrate ion concentration, initial phosphate ion concentration and adsorbent dose on the adsorption process efficiency are studied. Response-Surface Methodology-Central Composite Design statistical method is performed to reach the best conditions of the nitrate and phosphate ions removal percentages at neutral pH using Design Expert Software. The maximum nitrate and phosphate ions removal percentages (52.74 % and 92.38 %) are achieved using Fume Dust from an Electric Arc Furnace waste under these conditions; pH ~ 7, initial nitrate ion concentration = 6 mg/L, initial phosphate ion concentration = 1 mg/L, adsorbent dose = 6.5 g/L and contact time = 90 min.

Gedaren Spring is an important source of clean water and irrigation water that is located in the transition zone between the Gunungsewu Karst and the Wonosari Basin. Limestone dissolution is the dominant process influencing this epikarst spring’s dynamics, but there has been no temporal hydrogeological testing on its ion content. This hydrogeochemical study was intended to determine the characteristics and quality of Gedaren Spring water during the rainy season. The methods used in the chemical analysis were Schoeller, Piper, and chemographic diagrams, and the results were correlated with spring discharge measurements and rainfall. The chemical analysis showed a positive correlation between discharge and rain, the temporal presence of dominant ions, and temporal correlation patterns between variables. Ca2+ and HCO3- were the dominant cation and anion. The spring water was classified as calciumenriched, calcium, bicarbonate, Ca2+ + Mg2+, and HCO3--type groundwater and as unpolluted groundwater, suggesting good water quality. Chemographic patterns indicated that Mg2+, Cl-, and SO42- ions positively correlated with discharge and rainfall, while Ca2+, HCO3-, Na+, K+, pH, EC, temperature, and TDS negatively correlated with the two variables. Overall, Gedaren Spring has good chemical characteristics and quality during the rainy season has a dominant process of calcium enrichment and is of the type Ca2++Mg2+ and HCO3-.

Developing electronic platforms during education disruptions, particularly during the COVID-19 pandemic, had become crucial to addressing educational gaps. Research has shown technology's significant contribution to improving teaching and learning methods in labs, whether theoretical or experimental. This study creates an e-laboratory platform for managing university-level physics-chemistry practical work. The aim is to measure the platform's impact on students' experimental learning and identify integration and usage constraints. Our methodology was both quantitative and qualitative, conducted in a public institution. Two hundred forty students from two departments completed the questionnaire, and 25 teachers participated in semi-structured interviews. Findings revealed that e-laboratory simulations facilitated comparing theoretical solutions with actual lab practices and achieved goals in terms of communication pace, pre-lab content exchange (video conferences), post-lab experiment records, and evaluation sessions providing feedback for student progress tracking. However, insufficient computer equipment, technical problems during experiment setup, and momentary video conference issues hindered effective communication. This study guides researchers in enhancing adult education program efficiency. Considering online learning's adaptability and cost-effectiveness, improving learning effectiveness can justify continued use of online teaching beyond the pandemic by universities. Hence, electronic laboratories and the exploration of their integration transcend the realm of university scholars; they stand as a reservoir of potentiality for the perpetual advancement of professionals across diverse domains, affording a continuum of erudition throughout one's lifetime.

المقدمة: الشامات الشمسية هي واحدة من أشيع الآفات الجلدية المصطبغة الحميدة الناتجة عن التعرض المديد لأشعة الشمس. لها تأثير كبير جمالياً. تُقترح العديد من العلاجات لكن لا يوجد علاج واحد يعتبر الأكثر فعالية والأقل إحداثاً للآثار الجانبية. الآزوت السائل liquid nitrogen وحمض ثلاثي كلور الخل Trichloroacetic acid (TCA) هي خيارات فعالة وموفرة في علاج الشامات الشمسية. دراستنا تجري مقارنة بين هذين الخيارين لتحديد الأكثر فعالية والأقل آثاراً جانبية اعتماداً على النمط اللوني للبشرة. المرضى والمنهج: ٣٤ مريض لديهم شامات شمسية على ظهر اليدين (٤ مرضى نمط لونيII و١٩ مريض نمط III و١١ مريض نمط IV) خضعوا لجلستين علاجيتين بالآزوت السائل وTCA40% لليد اليمنى واليسرى على الترتيب بفاصل ٤ أسابيع بينهما. النتائج: أوضحت أن الآزوت السائل هو الأكثر قدرة على إحداث تفتيح مهم للآفات من ال TCA40% بفارق مهم إحصائياً P-value 0.01 لكنه كان أكثر ألماً واحتاج وقت أطول لشفاء الأذية التالية للعلاج. على الرغم من أن الآزوت السائل حقق نتائج أفضل لدى المرضى ذوي البشرات الغامقة إلا أنه سبب نقص تصبغ الأمر الذي يقترح كون الـTCA40% هو خيار أفضل لدى هؤلاء المرضى. الخاتمة: الآزوت السائل هو خيار أكثر فعالية في علاج الشامات الشمسية مقارنة مع TCA40% ولكن بالنسبة للمرضى ذوي البشرات الغامقة فإننا نفضل TCA40% تجنباً لحدوث نقص التصبغ.

Rice straw is one of the most common agricultural wastes due to its large production amounts. Energy valorization of rice straw is a technology used for nitrate removal as the produced ashes used to generate the adsorbent by means of an alkali dissolution followed by acid precipitation. The novelty of the proposed process is that the production of the nano zero-valent iron supported acid-activated rice straw (AARS-nZVI) adsorbent is carried out without the energy valorization process but, through an acid activation for rice straw followed by precipitation of nZVI particles on its surface. The new adsorbent synthesis, characterization and application were studied. Initial solution pH, initial nitrate concentration, adsorbent dose and contact time factors were considered during the investigation of nitrate removal efficiency using Central Composite Design (CCD) method. The optimum nitrate removal 91.62 % is obtained at initial pH of 7, initial nitrate concentration of 6 mg/L, adsorbent dose of 3 g/L and contact time of 180 min by using numerical optimization.

Abstract Background Idiopathic pulmonary artery aneurysm is a rare anomaly with only a handful reports in the literature. It is often asymptomatic, while the first presentation could be severe hemoptysis or death. Surgical intervention needs to be planned carefully with a multidisciplinary team approach to secure optimal outcome. We hope to spread our experience with such cases and to encourage other surgeons worldwide to deal surgically with these cases when its indicated. Case presentation A 47 years old man presented to our institution after three episodes of hemoptysis, echo demonstrated good left ventricle (LV) systolic function, normal right ventricle (RV) size and function, Chest computed tomography (CT) revealed aneurysmal dilatation with pending rupture of the pulmonary artery trunk (4.5 cm), the left pulmonary artery (6 cm) and the right pulmonary artery (2.3 cm). The patient successfully underwent replacement of Pulmonary artery trunk, left pulmonary artery and right pulmonary artery by Wovex Prosthetic graft (28 mm). The patient discharged home on the eight postoperative day in good clinical condition . Conclusion With this case report we wish to emphasize the need for a careful multidisciplinary approach given the complex and rare nature of the reported pathology.
