Authors: Zhu Feng , Kodakkadan Yoonusraj , Lakys Yahya
Published: August 2022

This article uses fifth-order nonlinear differential equations to describe the dynamic process of electrical automation control systems. This method first derives the equivalent system of the nonlinear fuzzy global system and then uses the orthogonal polynomial series expansion technique and its integral operation matrix. The local manifold at the dominant unstable equilibrium point of a single-machine infinite-bus system after a failure described by a two-dimensional quadratic nonlinear differential equation is calculated, and the stability boundary of the power system is obtained. The research results show that the output frequency fluctuation of the electrical automation control system is small after the algorithm is adopted, and the intelligent control system can accurately diagnose and warn the electrical faults. The system can meet the requirements of online voltage coordinated control.

Authors: Stephanie Anggilia , Makmun Dadang
Published: August 2022

Inflammatory bowel disease (IBD) has begun to emerge in Indonesia. The disease is further classifiedinto two types, ulcerative colitis (UC) and Crohn's disease (CD). Diagnosis of IBD is initiated from symptomfindings such as diarrhea, abdominal pain, bleeding diarrhea, and weight loss, and supported by physicalexamination and additional tests. The options for additional examinations of IBD are mainly endoscopy (esophagogastroduodenoscopy, colonoscopy, and also intestinal endoscopy), imaging techniques, and laboratory examinations either from blood or feces. The application of these modalities should be prompted by sufficientclinical suspicion to promote their efficiency as well as prevent underdiagnosis or overdiagnosis. In primaryhealth care settings, patients with IBD are expected to be recognized for therapy or to use appropriate referralsystem to warrant a proper treatment.Keywords: inflammatory bowel disease, diagnosis terkini, kolitis ulseratif, penyakit Crohn ABSTRAKInflammatory bowel disease (IBD) mulai banyak ditemukan di Indonesia.

Published: August 2022

Identification the causes of obstructive jaundice are challenging. Recent radiologic imaging techniques improve diagnostic yield to determine jaundice causes. However, small lesions particularly in pancreas or periampullary area that lead to jaundice, often unrecognize with conventional radiologic imaging. Radial endoscopic-ultrasound (EUS) is the most sensitive modality to identify the lesions-related obstructive jaundice, remarkably in the lack of high-resolution radiologic facilities. We presented four cases of obstructive jaundice, without obvious obstruction causes from conventional radiologic imaging or abdominal ultrasound. All patients underwent radial EUS, pancreatic head mass revealed in 2 patients, and distal stenosis of the common bile duct without evidence of mass was found in 2 other patients. The masses size were 16 mm and 39 mm in diameter. Due to linear EUS and EUS guided fine needle were unavailable in our center, confirmation biopsy was undone. Three patients were performed endoscopic retrograde cholangiopancreatography (ERCP) for dilatation and inserting stents, and one patient referred to the surgeon. In conclusion, radial EUS aided to diagnose the definite causes of jaundice despite in the less-equipped of high-resolution radiologic imaging.

Atrophic mandible fractures represent a clinical challenge due to both the peculiarities of the population involved and the management of a limited bone remnant. The choice of the type of osteosynthesis is guided by some criteria, including the degree of fracture comminution and the height of the bone remnant, where residual mandibular bone height <10 mm represents an important clinical challenge and is related to major postoperative complications. The aim of this study is to report the efficacy of the load-bearing osteosynthesis in a bilateral atrophic mandible fracture. An 86-year-old male patient, victim of a fall from his own height, evolving with a bilateral body fracture in the atrophic lower jaw. This fracture occurred adjacent to the endof a reconstruction locking plate installed 18 months ago to treat a fracture in the mandibular parasymphysis, requiring a surgical approach to removal the previous fixation and installation of two locking reconstruction plates in each fractured segment. Inthe six months of follow-up, no complication was observed. The uniqueness of this case reinforces the therapy with load-bearing plates and its clinical efficiency.

Authors: Ramirez-Ferrer Esteban , Abaunza-Camacho Juan Felipe , Pineda-Martinez Andres Felipe , Aguilera-Pena Maria Paula , Riveros-Castillo William Mauricio , Laverde-Frade Leonardo
Published: July 2022

Background:

Posttraumatic spinal cerebrospinal fluid leak (CSFL) without neurological deficit is a rare entity. Historically, the first-line treatment is a nonsurgical approach, which includes Trendelenburg positioning, carbonic anhydrase inhibitor (acetazolamide), and subarachnoid catheter, with a high successful rate of leak correction. However, in some cases, this first-line treatment could fail, being necessary the surgical approach.

Case Description:

A 23-year-old male with a recent stab wound to his lumbar region, complained of positional headache and fluid outflow through his wound. On physical examination, an active CSFL was detected without evidence of neurologic deficit. Imaging studies showed a CSF collection extending from the right L4 lamina to the subcutaneous tissue. CSF studies revealed bacterial meningitis. The treatment with carbonic anhydrase inhibitors, Trendelenburg position, lumbar subarachnoid catheter, and antibiotics was initiated. Failure of conservative measures prompted a surgical treatment to resolve the CSFL. Intraoperatively, a dura mater defect was identified, and an autologous paravertebral muscle flap was used for water-tight closure of the defect. The patient recovered without further complications and with CSFL resolution.

Conclusion:

Even though the nonsurgical approach is the first-line of treatment of traumatic CSFL cases, failures can occur. The evidence of a CSF trajectory in imaging studies could be a predictor of treatment failure of the nonsurgical treatment. The surgical treatment as second-line treatment has outstanding results regarding CSFL correction and should be considered when the prediction rate to nonsurgical approach failure is high.
Revascularization of the internal carotid artery through the hypertrophied vasa vasorum in traumatic carotid-cavernous fistula previously treated by ligation of cervical carotid arteries: A case report
Authors: Iampreechakul Prasert , Wangtanaphat Korrapakc , Lertbutsayanukul Punjama , Siriwimonmas Somkiet
Published: July 2022

Background:

Revascularization of the occluded internal carotid artery (ICA) through the vasa vasorum is exceedingly rare. Several previous studies hypothesized that the expansion of the vasa vasorum is associated with neovascularization related to the progression of atherosclerosis or plaque. The occurrence of reconstitution of the ICA through the vasa vasorum in traumatic carotid-cavernous fistula (TCCF) has rarely been reported.

Case Description:

We described an extremely rare case of a 64-year-old woman who developed reconstitution of the occluded ICA through hypertrophied vasa vasorum supplying recurrent TCCF previously treated by ligation of the internal and external carotid arteries. Usual endovascular treatment may be challenging for this patient due to inaccessible route from the affected ICA through multiple small vessels. The patient was successfully treated with trapping procedure and obliteration the fistula using combined surgical and endovascular treatment.

Conclusion:

We speculated that the hypertrophied vasa vasorum in TCCF may cause by a sequela of previous arterial injury, spontaneous recanalization of the occluded artery by the formation of vasa vasorum, and/or hypertrophy of the vasa vasorum due to the high flow of the fistula.

Predator Driven Trait Changes in Anolis smaragdinus
Authors: Wunderlich Samantha
Published: July 2022

Background: Research on the evolution of traits in regard to predator-prey relationships can illuminate the effects of migrating species and invasive species on native populations, which is increasingly relevant with heightened anthropogenic environmental disturbances shifting territories of native species.
Methods: We used a replicated field experiment to test the effects that predators have on the phenotype of Anolis smaragdinus in the Bahamas. It was predicted that A. smaragdinus would rapidly evolve over six generations to have shorter fore and hind limb lengths due to the presence of the predator, Leiocephalus carinatus, driving A. sagrei and A. smaragdinus into higher habitats, which selects for shorter limb lengths.
Results: ANCOVAs were performed for male and female A. smaragdinus, where only two of the thirteen measured traits, ulna length and third toe length in females, were found to have a significant year by treatment interaction between 2011 and 2017. We observed a general reduction in mean trait size when predators are present. Therefore, predators may be driving A. smaragdinus to higher perching sites which selects for smaller limb length. Also, it was found that populations of A. smaragdinus may be able to evolve in as little as six generations when predators and competitors are present.
Limitations: A longer study is needed to see if other trait changes would become significant over time, since the residual means are trending in one direction. Another suggestion is to do a study with fewer experimental islands and larger founder populations. This would violate the meaning of a true founder population; however, it may allow A. smaragdinus to become fully integrated within the new environment and lead to a smaller chance of extinction.
Conclusion: The study showed that the introduction of predators may cause significant phenotypic changes in female A. smaragdinus’ ulna and third toe length, while also showing a general reduction in mean trait size when predators are present. Therefore, predators may be driving A. smaragdinus to higher perching sites which selects for smaller limb length. However, the study did not show a significant change in either the fore limb length or the hind limb length between 2011 and 2017 which was predicted originally.
Physical Responses to Anthropogenic Disturbance on a Runway in the Canadian High Arctic
Authors: Rahman Tabatha , Lee Jeremiah
Published: July 2022

Background: The McGill Arctic Research Station (MARS) runway on Axel Heiberg Island, Nunavut, has been subject to intense compaction from aircrafts since the 1960’s, causing alterations to the landscape across time and space. This study investigated the thermal, hydrological and physical responses of repeated aircraft compaction of the runway to characterize its vulnerability to land use, and the effects of long-term and repeated compaction.
Methods: In late July and early August 2018, the island’s summer thaw season, topographic, soil, hydrological and frost table data were collected along four transects across the MARS runway.
Results: Topography and effective porosity differences caused by compaction were found to affect soil moisture contents, leading to the observed differential frost heaving and insulation properties of soil across the runway. Soil was found to be mostly silt on and off disturbed areas, indicating that compaction does not affect grain-size but rather pore space and soil bulk density. The frost table mapping suggested statistically significant variations in depth of the frost table across undisturbed, disturbed, and indirectly disturbed areas, showing that compression from aircrafts has both direct and indirect spatial impacts on the hydrogeomorphic system. Furthermore, this research examined possible solutions to mitigate thaw consolidation of the runway.
Limitations: The method of probing used to determine frost table depths introduced significant error to the data. Probing discrepancies arose between people probing and between sampling days, as techniques differed and/or improved. Future studies should consider using electrical resistance tomography to map the frost table, as this would eliminate inconsistencies. Furthermore, while pore size distributions were inferred based on grain-size and extent of compaction, subsequent studies should consider a quantitative approach to pore space analysis.
Conclusion: This study suggests that aircraft travel to the remote McGill Arctic Research Station causes spatially and temporally significant changes in the local hydrogeomorphology, especially in fine-grained and wet, frost-susceptible soils. Thaw consolidation, which results indicate is caused by the direct and indirect effects of soil compaction, compromises the prolonged use of the runway.

Published: July 2022

The article presents a methodology for evaluating tillage and seeding aggregates, taking into account soil and climatic conditions of farms. We offer a comprehensive assessment index of the performance of sowing machines and complexes for sowing crops, which takes into account productivity, fuel efficiency, sowing quality and reliability of the technological process to a certain point in time. Unit serviceability is measured by the ratio of the unit's capacity during the main time to the capacity during the shift time. Fuel consumption indicator for machines is the ratio of tillage depth, for seeders it is the sowing depth to specific fuel consumption. Soil cultivation quality is assessed by indicators of ridging and crumbling of the soil, the quality of sowing by the ratio of the actual seeding rate and the depth of seeding to the given technical specifications. The integral functions of the distribution of probabilities of failure-free operation in the form of an exponential law of distribution are used as an indicator of reliability assessment. For calculations, the results of agrotechnical and economic evaluation, taken from the protocols of machine tests at machine test stations, are used. Based on the research, effective sets of machines for the cultivation of crops, which are characterized by low costs, high quality of work and reliability, were proposed. In first place were taken by the grain seeders S-6PM2, SZP-3,6B, SZP-5,4, AMAZONE D9-60 Super; seeding complexes KSKP2,1D × 5 OMICH, Kuzbass PK-8,5, John Deere "730". The second place was taken by John Deere 455, ASTRA SZT-5,4, SKP-2,1D × 5, Pronto 12NT Horsch, DMC Primera 9000; seeding complexes Irtysh-10, AGRATOR-combidisk-9000, Kuzbass PK-9,7A.

Authors: Sazonov F. F.
Published: July 2022

Results of phenotypic evaluation of black currant genetic collection, selected forms, inbred and hybrid progeny by shrub habitus are presented. The possibility of using promising genotypes to produce the progeny with an optimal type of crowns was studied. Studies were conducted in 2017- 2021 in the conditions of the Bryansk region in the plots of the genetic collection, competitive study of selected forms, and hybrid black currant stock. The cultivation of black currants in the collection plantations and on the hybrid plot was carried out in accordance with the common in the Non-Black Earth Zone of Russia agro-technique. The weather conditions of the Bryansk region are typical for the Central region of Russia, the climate is moderately continental. Differentiation of varieties and selected forms by crown shape of plants was carried out. Hybridological analysis of inheritance of shrub habitus trait on the example of nine families from controlled crosses, three populations from self-pollination of genotypes different in shrub shape and three - from free pollination of promising black currant genotypes was performed. Varieties corresponding to the individual parameters of combine berry harvesting technology in terms of shrub habitus, base width, plant height were identified. These include the varieties Litvinovskaya, Myth, Rita, Kudesnik, Kudmig, Ben Hope, Nezhdanchik, Podarok Astakhova, Tamerlan, Tiben, Etyud, Chernavka and others, as well as a number of promising hybrids - 4-94-1, 3-80-01, 4-5-2, 4-19-04, 62-03-7, etc. The phenotypic evaluation of black currant progeny showed that the manifestation of the shrub habitus trait has a significant dependence on the crown type of the genotypes involved in the breeding work.
Comparison of hematological and biochemical parameters in COVID-19 pneumonia patients before and after convalescent plasma (CP) treatment
Authors: Polat Esra , Ürkmez Fatma Yekta
Published: July 2022

Background/Aim: Convalescent plasma (CP) therapy, which includes processing and administering antibody-rich plasma from recovered patients to sick patients, is used for passive immunity in COVID-19 pneumonia patients in addition to antivirals and antibiotics. This study aimed to assess whether CP treatment significantly affects hyperviscosity and COVID-19 prognosis-related blood parameters.

Methods: This study was a single-center retrospective cohort study. Ninety-seven patients with COVID-19 polymerase chain reaction (PCR)-positive results and pneumonia observed on thoracic computed tomography (CT) were included. Patients’ ferritin, d-dimer, C-reactive protein (CRP), and complete blood count levels before and after CP administration were compared.

Results: Ferritin, d-dimer, white blood cell (WBC), neutrophil, and plateletcrit (PCT) levels and the platelet distribution width (PDW) were significantly higher and there was a significant decrease in the CRP level after CP treatment compared to before CP (P < 0.05). Ferritin, d-dimer, and CRP values measured after CP were higher in deceased patients than in survivors (P = 0.001, P = 0.007, and P < 0.001, respectively)

Conclusion: Ferritin, d-dimer, WBC, and neutrophil levels, which we expected to decrease on the basis of the COVID-19 prognosis, unfortunately increased, and only CRP levels decreased. However, we found that these increases were more pronounced in patients who died. Considering these prognostic factors, the findings of our study suggest that CP treatment has no effect on the COVID-19 disease course and may lead to a worse prognosis.
CONDITIONS FOR THE FORMATION OF THE STRUCTURES OF THE MOZAMBIQUE BASIN (PHYSICAL MODELING)
Authors: Chupakhina Anastasia , Dubinin Yevgeny , Grokholsky Andrey
Published: August 2022

Based on the results of physical modeling, the conditions of formation of the Mozambique Ridge and the Beira High, formed during the opening of the Mozambique Basin, are considered. The Mozambique Ridge is a series of blocky uplifts rising up to 3500 m above the seafloor. One of the most probable hypotheses of the ridge origin suggests its partial separation from the margin of the African continent as a result of plume activity. Modern studies show that the northeastern part of the ridge is composed of thinned continental crust overlain by sedimentary cover, while its southern part is characterized by a large number of extrusive centers, indicating increased magmatic activity. Experimental studies have shown that the formation of the Mozambique Ridge occurred under the conditions of the African-Antarctic continental rift with the presence of structural heterogeneities in the lithosphere of the African continent and the influence of a hot spot. The Beira High is a continental block that was separated from Antarctica during the split of Gondwana.

Published: August 2022

La actividad física (AF) tiene un efecto positivo sobre la sintomatología menopaúsica y la calidad de vida. Altos niveles de comportamientos sedentarios (CS) se asocian a síntomas menopáusicos más severos. El objetivo fue evaluar la asociación entre la práctica de AF, los CS y la sintomatología menopaúsica percibida en mujeres de mediana edad. Estudio descriptivo, correlacional y transversal. Muestra de cien mujeres de 49.9 años (DE=4.56) del área metropolitana de Monterrey. Se aplicaron el Cuestionario Internacional de AF, acelerometría con equipos triaxiales ActiGraph™ wGT3X y el Cuestionario de Calidad de Vida Específico para la Menopausia. Análisis de datos con SPSS versión 21.0 y pruebas de correlación de Spearman.  El 66.7% de las participantes se dedicaba al hogar, los niveles socioeconómicos predominantes fueron el A/B y el C (alto y medio alto), el 88.1% era casada o vivía en unión libre, el 32.1% contaba con una licenciatura o el bachillerato y el 41.7% cursaba con obesidad. Se encontraron asociaciones inversamente proporcionales entre la sintomatología vasomotora y el promedio diario de minutos sedentarios entre semana (p<.05); asociación indirecta entre los síntomas físicos y el gasto energético por AF en el tiempo libre (p<.05). Conclusiones:  La práctica de AF en el tiempo libre se asocia con menor incidencia de sintomatología física de menopausia. Se encontró asociación entre la sintomatología vasomotora y los CS entre semana. El abordaje de dichas conductas debería ser considerado para el entrenamiento en mujeres que transitan esta etapa del desarrollo.

Authors: O Dochartaigh Domhnall , Ying Lisa , Simard Kristen , Eichorst Christina , Kaba Alyshah , Mews Lorissa , Chan Melissa , Brown Taryn , Kirkham Allison , Ma Warren
Published: July 2022

ABSTRACT
Background
Latent safety threats (LSTs) have been defined as system based issues that threaten patient safety that can materialize at any time and were previously unrecognized by healthcare providers, unit directors, or hospital administration. While LSTs such as system deficiencies, equipment failures, training, or conditions predisposing medical errors are frequently reported in the literature, a paucity was noted in the management and mitigation of these threats. The purpose of the translational simulation quality improvement project study was to utilize translational simulations to identify, manage, and mitigate future latent safety threats in our EDs.
METHODS
In 2017, 18 in-situ inter-professional simulation sessions were conducted at 11 EDs. Following each session, a survey assessment tool, created by the research team, was completed by participants to identify latent safety threats. Findings were shared with site clinical nurse educators and managers to help facilitate institutional follow up. For reporting, latent safety threats were categorized thematically and coded as either (i) resolved, (ii) ongoing, or (iii) not managed. Follow-up with sites was completed 1 year following the simulation.
RESULTS
A total n=158 LSTs were identified. The number and percentage by theme was: staff 48 (30.4%), equipment 41 (25.9%), medications 33 (20.9%), resuscitation resources 24 (15.2%), and information technology (IT) issues 12 (7.6%).Site follow-up identified that 149 LSTs were resolved and ten required ongoing work to manage. No occurrences of a LST ‘not managed’ were identified.
CONCLUSIONS
Translation simulation effectively identified latent safety threats and assisted interdisciplinary teams in the creation of a structured plan and systematic follow-up to enhance the health system and patient care. Through use of a threat mitigation strategy all identified threats were addressed while some require ongoing management.

Entrepreneurial beginnings: Transitions to self-employment and the creation of jobs
Authors: Fabling Richard
Published: July 2022

Owner-operated firms are an important part of the New Zealand economy. They employ approximately 30% of the private-for-profit workforce, as well as providing jobs and income to the working proprietors themselves. This paper addresses two questions: what characteristics are associated with entrepreneurship (starting a self-employed business); and which sorts of entrepreneurs are more successful (create jobs)? We pay particular attention to differences in start-up and survival rates by business owner sex and ethnicity, but also consider whether other individual characteristics (including age and skill) and prior job characteristics also relate to the decision to start a business or to create jobs. We find substantial negative gaps in entrepreneurship for females and non-European-only ethnicity groups – gaps that arise in large part because of differential rates of entry into self-employment and, in the case of nonEuropean-only ethnicities, higher attrition rates from self-employment after entry. These gaps persist in the presence of controls for skill, prior labour market experience and other individual characteristics.
Relatedness, complexity and local growth

Published: July 2022

We derive a measure of the relatedness between economic activities based on weighted correlations of local employment shares, and use this measure to estimate city and activity complexity. Our approach extends discrete measures used in previous studies by recognising the extent of activities' local over-representation and by adjusting for differences in signal quality between geographic areas with different sizes. We examine the contribution of relatedness and complexity to urban employment growth, using 1981–2013 census data from New Zealand. Complex activities experienced faster employment growth during our period of study, especially in complex cities. However, this growth was not significantly stronger in cities more dense with related activities. Relatedness and complexity appear to be most relevant for analysing how large, complex cities grow, and are less informative for understanding employment dynamics in small, less complex cities.
SOCIJALISTIČKA JUGOSLAVIJA I KAMILO KASTILJONI
Authors: Mišić Saša
Published: August 2022

After the breakup of relations with the Soviet Union and its satellites in 1948, Yugoslavia began to turn to Western countries, seeking not only formal but also informal ties for connecting with them, especially in the economic field. Italian financier Camillo Castiglioni seemed like a good choice for the role of unofficial mediator, especially because of the contacts he had with US financial circles. During 1949, the Yugoslavs hired him as an informal mediator for negotiations with the Export-Import Bank of the United States, in order to obtain a loan from this banking institution. An agreement was signed with him, in which he was promised an adequate reward for mediation. Since at the same time the official representatives of Yugoslavia and the United States were involved in the loan negotiations, and because of the indignation of the Americans over Castiglioni’s role, Belgrade quickly gave up his services. For his engagement, Castiglioni received compensation from Yugoslavia in the form of money and goods (hemp), which referred only to the costs of mediation, but did not include the promised commission. Taking advantage of the fact that he could not get the promised amount of money from the sale of hemp, Castiglioni initiated a lawsuit against Yugoslavia in an Italian court in 1951 and demanded that he be paid the difference in money, and also the amount of the promised commission. Although the court ruled in his favor that same year, Yugoslavia did not recognize the court’s decision. The next few years passed on the one hand in Castiglioni’s efforts to execute the court verdict and collect the claims, and on the other hand in the attempts of state officials in Belgrade and Rome to find a compromise solution that would satisfy the Yugoslavs. This included offers for a settlement, proposals for arbitration of an international court, and the like. The trial and the execution of the verdict took place at a time when Italy and Yugoslavia were trying to unravel the complicated knot of Trieste, so the Castiglioni case was also influenced by the situation in bilateral relations. Finally, in 1955, Castiglioni managed to collect the requested amount, which was paid off by the Italian state as a part of a broader Yugoslav-Italian agreement on war reparations.

Diabetes mellitus usually induce kidney and liver complications, characterized by an increase in transaminases activity. The aim of this study was to evaluate the activity of Gymnema sylvestre on the variation of tissue and serum transaminases activities in high sucrose diet and dexamethasone-induced diabetic rats. The animals were fed with high sucrose diet and 20% sugar water for 12 weeks then, received an intraperitoneal injection of dexamethasone (8mg/kg) once a day for 5 days between 07 and 08 am. After induction, the insulin sensitivity test was performed and the animals were divided into 7 groups. The experimental groups received extracts (aqueous and methanolic) and fractions (methylene chloride and methanol) of G. sylvestre once a day for 14 days. At the end of experiment, the animals were sacrificed and the blood, liver and kidney were collected for evaluation of transaminases and histopathology reduced by the plant. The activity of liver and kidney transaminases of the diabetic negative control (DNC) group on days 1 and 14 had significantly elevated (P<0.001) compared with this of the normoglycemic negative control (NNC) group and the different treated groups. This trend was also observed at the serum level but only with ASAT. Histological analysis revealed hepatic leukocyte infiltrations and mesangial expansions in the urinary space in the DNC group on days 1 and 14. These tissue abnormalities were corrected in groups receiving extracts and fractions of G. sylvestre. This study suggests that the extracts and fractions of G. sylvestre restore tissue damage in diabetic rats.

A simple, Precise, Accurate method was developed for the estimation of Molnupiravirby RP-HPLC technique. Chromatographic conditions used are stationary phase Agilent C18 (250 mm*4.6mm3.6m), Mobile phase Orthophopoaricacid: Acetonitrile in the ratio of 60:40 and flow rate was maintained at 1.0 mL/min, detection wave length was 254 nm, column temperature was set to 30o C and diluent was mobile phase Conditions were finalized as optimized method. System suitability parameters were studied by injecting the standard six times and results were well under the acceptance criteria. The retention time for Molnupiravir was 2.46 min. The method was validated for linearity, accuracy, precision, specificity, limit of detection, limit of quantification and robustness. Limit of detection and limit of quantification were found 0.06 μg/ml and 0.21 μg/ml respectively and recovery of Molnupiravir from tablet formulation was found 99.73%. The proposed method was successfully applied for the quantitative determination of Molnupiravir in tablet formulation.
