Lithium Dendrite Growth Process and Research Progress of its Inhibition Methods
Authors: Zheng Hao Ran
Published: April 2021

Metal lithium anodes, with extremely high specific capacity, low density, and lowest potential, are considered to be the most promising anode materials for next-generation high-energy density batteries. However, in the process of repeated plating and stripping of lithium, lithium dendrites are easily grown on the surface of the metal lithium anode, which greatly reduces the capacity of the battery, even causes hidden safety risks and shortens the battery life. This paper reviews the modification methods of lithium anodes based on the growth process of lithium dendrites, and introduces several current modification methods, including electrolyte additives, artificial SEI and new structure of lithium anodes. Finally, the future research direction and development trend of metal lithium anodes are prospected.

Recent Progress of Anode and Cathode Materials for Lithium Ion Battery
Authors: Liu Run Yu
Published: April 2021

Lithium ion battery is a kind of secondary battery that mainly relies on lithium ions moving between a positive electrode and a negative electrode. Lithium-ion batteries are considered to be the most ideal automotive power battery and has been widely applied in EV industry due to the outstanding advantages including but not limited to high energy density, high open circuit voltage and wide operating temperature range. The technical bottleneck of lithium-ion power batteries is how to further increase the energy density and optimize operating performance at low temperature. Besides, how to decrease the cost for lithium ion battery is also a big problem. The higher potential end of the power supply device is called cathode materials and the lower potential end of the power supply is called anode materials. At cathode end, Lithium ion intercalation process happens during discharging cycle and lithium ion deintercalation process happens during charging.For anode end, Lithium ion deintercalation process happens during charging cycle and lithium ion insertion process happens during discharging process. Good cathode/anode materials should include but not limited to the following characters: large specific capacity density, long cycling lifetime, good rate performance, proper electric potential and relatively stable structure during charge and discharge process.

Authors: Liu Zhao Yan , Liu Chuang , Li Dong , He Ti Ren
Published: April 2021

In this paper, the short beam shear (SBS) test combined with digital image correlation (DIC) and finite element model updating (FEMU) method is conducted for identification the constitutive parameters of unidirectional composite laminates by minimizing the objective function which is established based on the variance of measured strain and numerical calculated strain. This method has the advantages of insensitive to initial value and high identification efficiency. By changing the test parameters, specimens with different principal planes were used in the SBS test and different failure modes achieved. The standard deviation of E22C and E33C was 8.47% and 3.58% respectively. The comparison of the identification results of the same batch of specimens, different principal planes, different failure modes and different ROI shows that the results of constitutive identification using the area directly under the indenter is reliable.
Comparative study of recovery of airway reflexes and cognitive function following sevoflurane versus desflurane anaesthesia
Authors: Saha Mousumi , Saxena Kirti N , Wadhwa Bharti
Published: April 2021

Background and Aims:

Sevoflurane and desflurane have almost similar blood-gas solubility but recent studies suggest that desflurane compared to sevoflurane leads to faster recovery of airway reflexes, but the recovery of cognitive function varies significantly. We conducted this study to compare the times of recovery from anaesthesia following desflurane versus sevoflurane anaesthesia.

Methods:

This randomised double-blinded study was conducted on 60 patients of American Society of Anesthesiologists (ASA) classification I–II, age between 18 and 60 years with body mass index (BMI) ≤30 kg/m2 who underwent elective cholecystectomy. A standard general anaesthesia protocol was followed with either sevoflurane (group A = 30 patients) or desflurane (group B = 30 patients) along with bispectral index and neuromuscular monitoring. Following extubation, tests for recovery of airway reflexes and cognitive function were conducted and various time intervals were noted. Statistical analysis was carried out using Statistical Package for Social Sciences (SPSS) standard software version 17.

Results:

The mean time from first verbal response to first passing the swallowing test was comparable in both the groups (5.50 ± 3.45 vs. 4.10 ± 3.42 min, P value = 0.120). Patients receiving desflurane showed faster response to verbal commands (5.93 ± 4.13 vs. 8.20 ± 3.39 min, P value = 0.024), passed the swallowing test earlier (10.03 ± 4.97 vs. 13.70 ± 3.48 min, P value = 0.009) and Short orientation memory concentration test (SOMCT) earlier (9.83 ± 4.51 vs. 14.10 ± 4.31 min, P value ≤0.001) compared to sevoflurane.

Conclusion:

In patients undergoing laparoscopic cholecystectomy under controlled conditions, earlier recovery is seen with desflurane compared to sevoflurane.
A randomised comparative study of transversus abdominis plane block with or without intravenous diclofenac sodium as a component of multimodal regimen for post-operative analgesia following caesarean section
Authors: Kanta Bhati , Sonali Dhawan , Gazala Parveen , Yunus Khilji , Kiran Kuraning
Published: April 2021

Aims:

Post-operative analgesia is a major component of perioperative care. An ideal method of pain relief after caesarean section should be cost-effective and safe for mother and baby. This study aims to evaluate the analgesic efficacy of transversus abdominis plane (TAP) block combined with intraoperative diclofenac aqueous for post-operative analgesia in caesarean section.

Methods:

A prospective randomised double-blind study was conducted on 60 patients over a period of six months. Patients were enrolled in two groups (n = 30). Group A and Group B both received bilateral landmark based TAP block using ropivacaine 0.75% (1.5 mg/kg), 20 ml at end of surgery. Group B received diclofenac sodium aqueous 75 mg intravenous intraoperatively.

Results:

The difference of visual analogue score (VAS) at movement was significant at 4 and 6 h in Group A versus Group B (3.00 ± 0.64 versus 2.37 ± 0.89, 4.43 ± 0.68 versus 3.53 ± 1.2). At rest, VAS score was lower in Group B than in Group A at all time intervals (P < 0.05). Time to demand of first dose of rescue analgesic was prolonged in Group B (11.5 ± 4.1 h) than in Group A (7.55 ± 1.41 h). Mean dose of analgesic consumption in first 24 h was lesser in Group B (61.67 ± 34.57 mg) than in Group A (98.33 ± 37.68 mg). Patient satisfaction score was higher in Group B (8 ± 1.04) than in Group A (6.23 ± 1.04).

Conclusion:

TAP block along with intraoperative diclofenac aqueous as component of multimodal regimen provides superior post-operative analgesia and better patient satisfaction as compared to TAP block alone.

Published: April 2021

Uapaca togoensis Pax. (Euphorbiaceae) is used in traditional medicine to treat several diseases including pain, inflammation and fever. This study investigated analgesic, anti-inflammatory and anti-pyretic effects of the residual aqueous fraction of the plant. Preliminary phytochemical screening and acute toxicity studies were conducted. Analgesic activity was evaluated using acetic acid-induced writhing, hot plate and formalin-induced pain tests at doses of 250, 500 and 1000 mg/kg, p.o. Anti-inflammatory and antipyretic activities were investigated using carrageenaninduced paw edema and Brewer’s yeast-induced pyrexia model respectively in rats. Oral median lethal dose of the fraction was found to be greater than 5000 mg/kg. The fraction significantly (p<0.05) reduced the number of acetic acid-induced writhes and increased the reaction time of mice to thermal stimuli. In the formalin test, a significant (p<0.05) reduction in mean pain score was observed at the second phase. A significant (p<0.05) decrease in paw edema at the 4th and 5th hours and a reduction in temperature was also observed at the 22nd hour. Phytochemical screening revealed the presence of saponins, tannins, steroids, cardiac glycosides, flavonoids, alkaloids and triterpenes. The result of the study revealed that the fraction possesses analgesic, anti-inflammatory and antipyretic activities, validating the folkloric use of the plant.

Authors: Ilomuanya Margaret O. , Ubani-Ukoma Uloma N. , Sowemimo Abimbola A. , Akande Gbemisola W. , Kunal Pal
Published: April 2021

The rationale for this study was to increase the absorption of model drug metronidazole by formulating an organogel using detarium oil in place of conventional oils used in drug formulation such as liquid paraffin. The organogels were prepared by fluid-filled mechanism using metronidazole as the model drug. The drug-surfactant mixtures were dissolved in oil followed by the addition of water which led to the formation of organogels at specific compositions. The formulations were analyzed by microscopy, rheology, in vitro drug release and X-ray diffraction (XRD). Microscopic studies revealed the gels contained clusters of water-filled spherical structures. FTIR study showed compatibility of components of the organogels. DSC result showed all the organogels released heat during formation. The viscosity of the organogels showed an elastic flow followed by a non-elastic phase. The cumulative percentagerelease of metronidazole was found to be between 63% and 85% at the end of 10 h, with OGM 9 having the highest release. XRD result indicated the crystalline nature of the organogels. Metronidazole release from the organogels indicated dissolution, shape, size, and surface area dependent release. The results also showed good compatibility of all the excipients. Sustained release metronidazole organogel was successfully developed using detarium oil.

Prolapsed ileocolic intussusception in an adult : A bizarre presentation leading to delayed diagnosis in a low resource setting
Authors: Umar M. , Stephen Y. , Aminu U. , Adogu I.
Published: April 2021

Background: Intussusception is the telescoping of one part of the intestine into the lumen of the adjoining part, which occurs more in the ileocaecal part of the intestine. It is the most common cause of intestinal obstruction in children younger than 3years of age. Occurrence is rare in adult, with prolapsed intussusceptions even rarer and occuring more in association with an underlying predisposing intestinal abnormality.Case Report: A 19year old boy presented with 6months history of recurrent non-specific, occasionally dull aching abdominal pain, progressive weight loss and a 4hour history of anal protrusion. He had presented multiple times to a peripheral hospital where the definitive diagnosis was missed. He was evaluated for ileocolic intussusception and he had exploratory laparotomy and right hemi colectomy done.Conclusion: Intussusceptions are rare outside childhood, however there should be a high index of suspicion of intussusception in adult with nonspecific abdominal symptoms who has not responded to conventional conservative therapy.

The present work deals with the production of biodiesel from Sandbox (Hura crepitans) seed oil and the optimization of the parameters that influence the transesterification of Sandbox (Hura crepitans)seed oil into biodiesel using Response Surface Methodology. Hura crepitans oil was obtained from by using hydraulic press for Mechanical and n-hexane for solvent extraction. Esterification was done using methanol and sodium hydroxide. A total of 48 experiments using Central Composite Design were carried out. The R-Squared, Adequate Precision, Predicted and Adjusted R-Squared values were 0.9367, 19.219, 0.8576 and 0.9070 respectively. The result of the extraction of oil, physiochemical properties, and optimization process shows that sandbox (Hura crepitans) seed oil has characteristics that are more favorable to biodiesel production. The optimal conditions for extraction of oil from sandbox seed oil were given as alcohol/ oil ratio of 5.0, catalyst amount of 20 g/ml, extraction temperature of 60 ºC, and extraction time of 45.01 minutes, with the predicted oil yield as 97.33% respectively which shows that the experimental values are in good agreement with predicted values.
TTS-driven Embodied Conversation Avatar for UMB-SmartTV
Authors: Rojc Matej , Kačič Zdravko , Presker Marko , Mlakar Izidor
Published: April 2021

When human-TV interaction is performed by remote controller and mobile devices only, the interactions tend to be mechanical, dreary and uninformative. To achieve more advanced interaction, and more human-human like, we introduce the virtual agent technology as a feedback interface. Verbal and co-verbal gestures are linked through complex mental processes, and although they represent different sides of the same mental process, the formulations of both are quite different. Namely, verbal information is bound by rules and grammar, whereas gestures are influenced by emotions, personality etc. In this paper a TTS-driven behavior generation system is proposed for more advanced interface used for smart IPTV platforms. The system is implemented as a distributive non-IPTV service and integrated into UMB-SmartTV in a service-oriented fashion. The behavior generation system fuses speech and gesture production models by using FSMs and HRG structures. Features for selecting the shape and alignment of co-verbal movement are based on linguistic features (that can be extracted from arbitrary input text), and prosodic features (as predicted within several processing steps in the TTS engine). At the end, the generated speech and co-verbal behavior are animated by an embodied conversational agent (ECA) engine and represented to the user within the UMB-SmarTV user interface.
Applied Systems Theory: Wind Turbine Output Power Prediction based on Wind Energy Utilization Coefficient
Authors: Wang Xiaotong , Niu Wangqiang , Gu Wei
Published: April 2021

The output power of a wind turbine is the most critical variable reflecting the operating status of the turbine. To improve the interpretability of the prediction model, a segmented output power method based on wind energy utilization coefficient is established. First, the wind energy conversion system of the wind turbine is given, and the SCADA data of a wind turbine is visually analyzed. Then it is proposed to separate the data into three groups according to different operating regions of wind turbines: the Maximum Power Point Tracking region, the rotator speed control region, and the power control region. In the Maximum Power Point Tracking region, wind energy utilization coefficient is found by a fitted cubic polynomial of the tip speed ratio. In the rotator speed control region, a modeling method for determining wind energy utilization coefficient through dynamic labels is designed. In the power control region, the output power is kept at the rated value. Finally, the 3 models are connected so that time-series data can be handled. The SCADA data of a 2.1MW wind turbine is used to verify the above models. The performance of these models is given in the form of Root Mean Square Error, indicating that the output power predicted by this method has good accuracy.The segmented output power model based on wind energy utilization coefficient can simulate the operation process of wind turbines, and has good accuracy and interpretability.

Published: April 2021

Practice Problem: Unwarranted antibiotic prescribing practices when treating acute respiratory illnesses contribute to the national health threat of antibiotic resistance. PICOT: In a pediatric outpatient setting for patients ages 6-25 who have no documented uncontrolled comorbidities, presenting with an acute respiratory illness (P), does provider utilization of clinical guidelines, and patient and (caregivers) utilization of educational pamphlets, to collectively develop a plan of care (I), compared to providers and patients who do not utilize such strategies(C) result in a reduction in antibiotics prescribed for acute respiratory illnesses (O) in a 6-week timeframe (T)? Evidence: The evidence reviewed reported the utilization of clinical treatment guidelines accompanied with patient education, and the collaborative formation of the plan of care when treating acute respiratory illnesses, resulted in a modest or profound reduction in antibiotics prescribed. Intervention: Provider usage of The Centers for Disease Control (CDC) clinical guidelines accompanied by patient education to collaboratively formulate the treatment plan for the management of patients presenting with acute respiratory illnesses. Outcome: Antibiotic prescribing rates when managing acute respiratory illness declined from 82% baseline to 42% post-intervention. Conclusion: Provider utilization of CDC clinical guidelines, with patient education to collectively formulate a management plan when treating acute respiratory illnesses resulted in a reduction in non-medically indicated antibiotic prescriptive practices.

Authors: A Lalithasyamala and Dr.D Ravi Kishore
Published: April 2021

In this paper, analysis of solar power fed Brushless DC motor (BLDC) motor drive with a boost converter is
presented for water pumping application in irrigation system. Nowa days, the usage of renewable PV source
is increasing gradually, due to the encouragement of eco-friendly energy sources by providing subsidies for
the installation in the initial states. In the agricultural sector, the water pump system requires a 3-ϕ power
supply, for that we need a separate transmission line and transformers to meet the load demand. In this
paper, a solar power fed BLDC motor water pumping system with boost converter and Voltage source
Inverter (VSI) is presented which reduces the converter switch stress by increasing the voltage transfer gain
ratio. VSI needs a huge dc link capacitor that is inherently unreliable and is one of the most expensive
components of a drive.A MPPT controller is required to extract maximum power from the high penetrating
renewable PV source and also proposes the Current source inverter (CSI) fed water pumping system is
developed and examine with same operating conditions. A comparative analysis view in existing method of
system replace the VSI with CSI. The performance of system is analyzed with speed settling times at same
operating conditions. The proposed work is carried out in the MATLAB/Simulinksoftware. A comparative
analysis is also presented in lucid manner

Published: April 2021

Indonesia pada 9 Desember 2020 akan melaksanakan Pemilihan Kepala Daerah dan Wakil Kepala Daerah (Pilkada). Berbeda dengan Pemilu Serentak yang mengalami kenaikan angka partisipasi, Pilkada Serentak 2020 dibayangi oleh rendahnya minat masyarakat untuk datang ke TPS karena Pilkada dilaksanakan ditengahdi tengah Pandemi Covid-19. Kendati demikian, KPU tetap optimis jika partisipasi pada Pilkada nanti tetap tinggi sehingga KPU berani memasang target angka partisipasi sebesar 77,5%. Untuk mewujudkan optimisme tersebut diperlukan sebuah strategi untuk mendongkrak minat pemilih. Strategi tersebut antara lain pertama, menyusun strategi komunikasi dan teknis guna mendorong minat serta memberi kemudahan pelayanan pemberian suara. Kedua, penyelenggara dapat memaksimalkan sosialisasi secara daring dengan platform berbagai bentuk media sosial. Ketiga, penyelenggara memberikan insentif kepada pemilih dengan pemberian masker saat pemilih datang ke TPS sebagai bentuk kepedulian penyelenggara atas jaminan kesehatan setiap pemilih.
PERILAKU PENYELENGGARA PEMILU DALAM TAHAPAN DISTRIBUSI LOGISTIK DAN ANTISIPASI PERILAKU PADA MASA PANDEMI COVID-19
Authors: M Tahir Muchlas
Published: April 2021

Artikel ini mengulas tahapan distribusi logistik dan perilaku penyelenggara Pemilu dan antisipasi perilaku penyelenggara pada masa pandemi Covid-19. Metode penelitian ini, dilakukan dengan pendekatan kualitatif yang mendeskripsikan kejadian dan peristiwa yang terkait dengan penyelenggaraan pemilu khususnya pada tahapan distribusi logistik. Pengumpulan data dilakukan dengan menggunakan wawancara dengan informan penyelenggara pemilu di Kabupaten Buton Tengah. Aktivitas analisis data dilakukan melalui reduksi data, penyajian data, dan penarikan kesimpulan. Hasil analisis dan diskusi/pembahasan menunjukkan bahwa terdapat sejumlah permasalahan terkait logistik pemilu yang tiba tidak tepat waktu pada saat penjemputan, tidak semua jenis logistik tiba di tempat, logistik tiba hanya sebagian saja sehingga hal tersebut memperlambat kinerja aparatur penyelenggara pemilu dan relawan yang bertugas meskipun pada akhirnya dapat diatasi oleh penyelenggara pemilu sehingga pemilihan umum dapat dilaksanakan. Dari aspek kontrol politik tidak ditemukan keterlibatan aktif anggota dewan dan tokoh masyarakat dalam pendistribusian logistik. Dari aspek kontrol organisasi menunjukkan pengawasan internal KPU Kabupaten Buton Tengah dilakukan oleh Ketua KPU Kabupaten Buton Tengah dan TIM yang berasal dari luar KPU seperti Bawaslu Kabupaten Buton Tengah dan pihak Kepolisian. Kemudian dari aspek profesionalisme menunjukkan bahwa penyelenggara pemilu dan relawan demokrasi memiliki kinerja yang baik dan sudah dapat dikatakan profesional. Namun, kelemahannya adalah karena kekurangan personel. nantinya implementor perlu menjaga sarana dan prasarana sesuai dengan Protokol Kesehatan Pencegahan Covid-19 mulai dari sterilisasi tempat pemungutan suara, penggunaan Alat Pelindung Diri (APD) seperti masker atau face shield, menyediakan handsanitizer/tempat cuci pada TPS dan menerapkan social distancing pada saat pemungutan suara.

Penundaan Pemilihan serentak tahun 2020 akibat pandemi covid-19 yang dinyatakan sebagai bencana nasional, harus dapat memberikan kepastian hukum dan menjamin sistem politik pemilu di Indonesia tetap menciptakan sistem demokratisasi dalam Pemilihan sesuai dengan amanat Pancasila dan UUD 1945. Penundaan Pemilihan serentak tahun 2020 dilakukan sebagai bentuk nyata bahwa apabila Pemilihan serentak tahun 2020 tetap akan dilaksanakan, dampak yang paling terkena adalah masalah kesehatan. Oleh karena itu, metode yang digunakan untuk mengkaji permasalahan ini adalah metode normatif analisis atau disebut juga penelitian doktrinal, yang menyatakan bahwa hukum identik dengan norma-norma tertulis yang dibuat dan diundangkan oleh lembaga atau pejabat yang berwenang. Melalui kajian penelitian ini diharapkan, Pemerintah segera menyusun regulasi baru yang mengakomodir terjadinya force majeure seperti bencana nonalam. Penundaan Pemilihan lanjutan dapat dipergunakan sebagai kontrol atau persiapan terhadap penggunaan teknologi informasi dan komunikasi (TIK) sebagai perangkat penunjang aktivitas Pemilihan di tengah pandemi covid-19 serta dapat sebagai kontestasi politik sekaligus sebagai momentum terhadap perbaikan sistem Pemilihan oleh pemerintah. Selain itu, Penundaan Pemilihan lanjutan tahun 2020 sangat tepat dilaksanakan dengan pertimbangan bahwa, lebih berharga masalah kesehatan dan nilai keselamatan manusia daripada sebuah nilai Pemilihan serta hal ini sudah sesuai dengan perintah konstitusi sesuai dengan prinsip Salus populi suprema lex esto.

Na perfuração de poços que contém petróleo, são utilizadas brocas que ao penetrarem na matriz rochosa geram fragmentos, que são conhecidos como cascalho. O cascalho é transportado até a superfície pelo fluido de perfuração que possui baixa biodegrabilidade, fazendo com que seja necessária uma separação para que o cascalho possa ser descartado de forma adequada ao meio ambiente. A secagem via micro-ondas está sendo utilizada para a descontaminação desses cascalhos, pois apresenta alta eficiência de remoção comparada a equipamentos convencionais. O aquecimento micro-ondas é fortemente influenciado pela composição química da matriz rochosa. Sendo assim, neste trabalho foram verificados a influência da presença dos óxidos de ferro, alumínio, manganês e cálcio no aquecimento micro-ondas de um arenito. Os testes foram efetuados em um micro-ondas de bancada adaptado, a fim de se verificar como as variações de composição afetam a cinética de temperatura e taxa de aquecimento. Com base nos resultados obtidos, foi possível identificar que o óxido de ferro possui maior sensibilidade às micro-ondas comparado ao óxido de alumínio, devido ao fato das propriedades eletromagnéticas presente no ferro, acarretando em maior taxa de aquecimento. O óxido de manganês foi o que apresentou maior taxa de aquecimento, porém, foi observado uma anormalidade no aquecimento da amostra após certo tempo de exposição às micro-ondas. Por não absorver de forma adequada às micro-ondas, o óxido de cálcio foi o que apresentou menor taxa de aquecimento em comparação aos demais. Com os resultados obtidos, foi possível também desenvolver uma correlação para prever como cada tipo de óxido estudado comporta ao ser submetido ao aquecimento micro-ondas.

Swarming periods of parasitic ants from the subgenus Chthonolasius observed in the Hauts-de-France region (Hymenoptera: Formicidae: Formicinae). - Swarming periods of parasitic ants from the subgenus Chthonolasius are studied in Northern France. This work, carried out between 2014 and 2020, improves our understanding of their strategy for parasitising host species. The role of insect traps for the study of this group of insects is underlined, especially the light traps which seems to be the most effective technique for detecting individuals belonging to this subgenus. The data collected also makes possible to question the patrimonial value of these species.

Penyebaran virus Corona berdampak pada pelaksanaan misi gereja. Gereja yang selama ini melakukan berbagai aktivitas keagamaan secara fisik terpaksa harus menggunakan berbagai media digital agar orang Kristen tetap dapat mendapatkan pelayanan. Meskipun begitu, pelayanan-pelayanan gereja yang bersifat virtual tersebut belumlah maksimal menjangkau kelompok-kelompok masyarakat seperti Generasi Z dan mereka yang tidak memiliki kemampuan untuk mengaksesnya. Tujuan dari penelitian ini adalah menemukan solusi yang dapat gereja lakukan untuk menjangkau komunitas yang belum terjangkau oleh pelayanan gereja secara digital. Berdasarkan kajian dengan menggunakan metode deskriptif-analisis, penulis berkesimpulan bahwa penatalayanan gereja di sosial media janganlah hanya berfokus pada aspek ibadah tetapi juga pada pemuridan yang akan mendewasakan iman orang percaya dan pada akhirnya anggota jemaat baik yang tua maupun muda dapat dilibatkan untuk membantu gereja dalam mengembangkan pelayanan di masa pemberlakuan jarak fisik bahkan setelahnya.
Estimation of chemical safety of environmental protection technologies for atmosphere pollution reduction (a case study of processess of laser treatment of polymer materials)
Authors: Malysheva Alla G.
Published: April 2021

Introduction. One way to protect atmospheric air from industrial pollution is the use of environmental protection technologies aimed at emissions purification. As a result of the man-induced impact, the industrial emissions can change the composition of air medium, while the resulting products of physical and chemical transformations with other, sometimes more toxic properties, can influence on the quality and chemical safety of atmospheric air in comparison with the initial substances entering it as part of industrial emissions. Materials and methods. Studies of the impact of various technologies of treatment the industrial atmospheric emissions of organic glass and polymer materials processing plants with laser systems were carried out using a chromato-mass spectrometric system Focus GC with DSQ II (USA). Results. We have established the change in the qualitative-quantitative composition of emissions from organic glass laser treatment processes using various cleaning devices. Estimation of electrostatic purification technology efficiency based on plasma-catalytic oxidation with atomic oxygen revealed an increase in the transformation products - aldehydes. The cleaning devices seems ineffective and chemically unsafe concerning one of the primary pollutants included in the emissions of organic glass and polymer materials processing plants with laser systems - methyl methacrylate. Conclusion. The use of new environmental protection technologies for emissions purification can cause a change in their qualitative-quantitative composition, which requires chemical-analytical control. It is advisable to use chromatography-mass spectrometry to identify and quantify up to 100 substances simultaneously in the air with an unknown composition of pollutants to assess the efficiency and chemical safety of new technologies for emissions purification adequately. It will certainly reduce and minimize health risks and allow considering the possibility of man-induced formation of transformation by-products.
Respiratory protective devices for the healthcare workers (literature review)
Authors: Kaptsov Valery A. , Chirkin Alexander V.
Published: April 2021

Introduction. Healthcare practitioners are at increased risk of infection with infectious diseases, including the inhalation route. Healthcare practitioners use respirators of various designs providing different efficiency of protection. The purpose of the study was to improve efficiency of the respiratory protection of the healthcare practitioners in Russian Federation. There were analyzed available NIOSH publications, articles in journals Taylor & Francis, Oxford University Press, published materials of Federal Service for Supervision of Consumer Rights Protection and Human Welfare (Rospotrebnadzor), and western training manuals. Differences in the requirements of the legislation were identified that increase the risk of infection in healthcare practitioners. There are no methods for assessing the risk level, and there are no specific requirements for selecting the respirator’s type that corresponds to the risk level. The employer is not obliged to provide the fit test for all employees. The respirator must be used timely, so it should not negatively affect the worker. But the average carbon dioxide concentration can exceed the STEL by more than two times. The certification requirements for respirators do not correspond to the conditions of their use in the hospitals. Respirators were not certified as means of protection against bioaerosols. Conclusions. Identified shortcomings in the respiratory safety of health care workers show possible ways to improve their protection by harmonizing national legislation with the best of existing Western requirements.

â€œThe destruction / break / rupture / discontinuity of body tissue / part of body, is called Vrana.â€A clean wound in a normal body heals earlier with a minimum scar as compared to contaminated wound. Wound healing is mechanism where the body attempts to restore the integrity of the injured part. Several factors affects the normal process of wound healing such as the site of wound, contamination (foreign bodies/bacterial), local factors like vascular insufficiency or previous radiation, systemic factors such as malnutrition, Disease like diabetes mellitus, Immune deficiencies and medicationsÂ  like steroids.Â  Acharya Sushruta mentioned 60 Upakramas for the management of Vrana and local application of DurvaTail Vrana Basti is one among them. The local application of VranaBasti is one of the best substitutes for of chronic wound healing & the DurvaTail have better shodhana & ropana effect. A case report of 34 year â€“ old man, who presented with complaints of an open traumatic ulcer on the dorsum of the right foot associated with pain, discharge, slough, foul smell, oedema and discolouration of the skin has been presented here.
Verification of Internal Oleation Doses mentioned by Vangasena to achieve proper Oleation before Vamana and Virechana
Authors: Wetal Vishakha Rajesh
Published: April 2021

Background -Maximum(Pradhan), minimum(heena) and medium(madhyam) doses forÂ  internal oleation pursued as preparation, before Vamana (induced vomiting for therapeutic purpose) and Virechana (induced purgation for therapeutic purpose) is mentioned in all three Ayurveda classic texts (Brihat-trayi), on the basis of time required for its digestion and doshavastha.. This method is very subjective contrary to the objective evaluation affirmed in Vangasen-Snehpanadhikar(VS), where evaluator does not make any judgment. The actual dose quantification, in increasing order for shodhan purpose is mentioned in VS. Objective-To verify suitability of internal oleation doses cited in Vangasen to achieve Samyak Snigdha Lakshanani(SSL) and to monitor its complications if any.Â Â Â Â Method - This method was applied for 18 patients intended for either Vamana or Virechana to verify its authenticity to achieve SSL. Sixteen patients were given medium dose and two were given maximum dose. Oleation was discontinued as soon as SSL were achieved.Result-Out of 18 patients one achieved SSL in three days, five in four days, six in five days and five patients in six days. One patient took seven days to achieve SSL. Out of 18 patients, on last day one digest sneha in 2 hrs, 3 digest it in 4 to 5 hrs, 9 in 6 to 7 hrs, and 5 patients took 10 to 15 hrs to digest sneha on the day of completion of Snehana. Complications were not observed in any patient.Conclusion-Medium or maximum doses specified in VS, can be used for internal oleation before Vamana and Virechana to achieve SSL without any complication. Thus the method is practical one.Â
