Operational water forecast ability of the HRRR-iSnobal combination: an evaluation to adapt into production environments
Authors: Meyer Joachim , Horel John , Kormos Patrick , Hedrick Andrew , Trujillo Ernesto , Skiles S. McKenzie
Published: January 2023

Abstract. Operational water-resource forecasters, such as the Colorado Basin River
Forecast Center (CBRFC) in the Western United States, currently rely on historical records to calibrate the temperature-index models used for
snowmelt runoff predictions. This data dependence is increasingly
challenged, with global and regional climatological factors changing the
seasonal snowpack dynamics in mountain watersheds. To evaluate and improve
the CBRFC modeling options, this work ran the physically based snow energy
balance iSnobal model, forced with outputs from the High-Resolution Rapid
Refresh (HRRR) numerical weather prediction model across 4 years in a Colorado River Basin forecast region. Compared to in situ, remotely sensed, and the current operational CBRFC model data, the HRRR-iSnobal combination
showed well-reconstructed snow depth patterns and magnitudes until peak
accumulation. Once snowmelt set in, HRRR-iSnobal showed slower simulated
snowmelt relative to observations, depleting snow on average up to 34 d
later. The melting period is a critical component for water forecasting.
Based on the results, there is a need for revised forcing data input
preparation (shortwave radiation) required by iSnobal, which is a
recommended future improvement to the model. Nevertheless, the presented
performance and architecture make HRRR-iSnobal a promising combination for
the CBRFC production needs, where there is a demonstrated change to the
seasonal snow in the mountain ranges around the Colorado River Basin. The
long-term goal is to introduce the HRRR-iSnobal combination in day-to-day
CBRFC operations, and this work created the foundation to expand and
evaluate larger CBRFC domains.
More than one landslide per road kilometer – surveying and modelling mass movements along the Rishikesh-Joshimath (NH-7) highway, Uttarakhand, India

Published: January 2023

Abstract. The rapidly expanding Himalayan road network connects rural mountainous regions. However, the fragility of the landscape and poor road construction practices lead to frequent mass movements along-side roads. In this study, we investigate fully or partially road-blocking landslides along the National Highway (NH-) 7 in Uttarakhand, India, between Rishikesh and Joshimath. Based on an inventory of > 300 landslides along the ~250 km long corridor following exceptionally high rainfall in October and September 2022, we identify the main controls on the spatial occurrence of mass-movement events. Our analysis and modelling approach conceptualizes landslides as network-attached spatial point pattern. We evaluate different gridded rainfall products and infer the controls on landslide occurrence using Bayesian analysis of an inhomogeneous Poisson process model. Our results reveal that slope, rainfall amounts, and lithology are the main environmental controls on landslide occurrence. The individual effects of aggregated lithozones is consistent with previous assessments of landslide susceptibilities of rock types in the Himalayas. Our model spatially predicts landslide occurrences and can be adapted for other rainfall scenarios, and thus has potential applications for efficiently allocating efforts for road maintenance. To this end, our results highlight the vulnerability of the Himalayan road network to landslides. Climate change and increasing exposure along this pilgrimage route will likely exacerbate landslide risk along the NH-7 in the future.
Revisiting the wintertime emergent constraint of the southern hemispheric midlatitude jet response to global warming
Authors: Breul Philipp , Ceppi Paulo , Shepherd Theodore G.
Published: January 2023

Abstract. Most climate models show a poleward shift of the southern hemispheric zonal-mean jet in response to climate change, but the inter-model spread is large. In an attempt to constrain future jet responses, past studies have identified an emergent constraint between the climatological jet latitude and the future jet shift in austral winter. However, we show that the emergent constraint only arises in the zonal mean and not in separate halves of the hemisphere, which questions the physicality of the emergent constraint. We further find that the zonal-mean jet latitude does not represent the latitude of a zonally coherent structure, due to the presence of a double-jet structure in the Pacific region during this season. The zonal asymmetry causes the previously noted large spread in the zonal-mean climatology but not in the response, which underlies the emergent constraint. We therefore argue that the emergent constraint on the zonal-mean jet cannot narrow down the spread in future wind responses, and we propose that emergent constraints on the jet response in austral winter should be based on regional rather than zonal-mean circulation features.

A study was conducted to assess the growth performance of pre-ruminant crossbred calves maintained on different feeding strategies. Eighteen four days old crossbred calves were selected from University Livestock Farm and Fodder Research and Development Scheme, Mannuthy. The calves were randomly allotted to three dietary treatments- T1 (fed with milk @ 1/10th of body weight during first six weeks, 1/15th of body weight during next two weeks, 1/20th of body weight during next four weeks), T2 (fed with milk at 15 per cent of body weight for first month and weaned at six weeks of age) and T3 (fed with milk replacer (22 per cent CP) at 15 per cent of body weight for first month and weaned at six weeks of age. Calf starter having 22 – 24 per cent CP and 70 per cent TDN was fed to T1 and one with 20 per cent CP and 70 per cent TDN) was fed to T2 and T3 as per standard feeding practices followed in the farm. Average daily gain and body weight gain were higher (p<0.05) in T2 compared to T3. However outcome of groups T2 and T1 and the comparison of the aforesaid parameters between T3 and T1 were similar. The fortnightly average daily dry matter intake of the calves did not differ between the various groups except for the fourth and fifth fortnight. The mean feed conversion ratio of experimental calves of T1, T2 and T3 were 3.46 ± 0.09, 3.11 ± 0.23 and 3.41± 0.19 respectively and the values were statistically similar (p>0.05).

The study was conducted to assess the effect of supplementation of Moringa oleifera leaves on reproductive performance in Malabari doelings. Apparently healthy Malabari kids (n=32) of age three months were selected and randomly allocated to two different treatment groups. Control group (T1, n= 16) was fed with complete feed as pellets and experimental group (T2, n=16) was given complete feed pellets in which 50 per cent of concentrate was replaced with M. oleifera leaves on dry matter (DM) basis. The mean initial and final body weight and dry matter intake did not differ significantly but showed a linear increase in both the groups. Haematological parameters (Hb, Haematocrit, TEC, TLC) did not vary significantly between groups, however, mean total protein was significantly higher (p< 0.05) and mean ALT was significantly lower in T2. Post weaning mean progesterone profile remained less than 1ng/mL until fifth month of age, showed significant increase during sixth month (T1- 0.24 ng/mL, T2- 0.44ng/mL; p< 0.5) and was elevated more than 1ng/mL during seventh month in T2 (T1- 0.72 ± 0.22 ng/mL, T2- 1.14 ± 0.29 ng/mL). First behavioural oestrus was observed during sixth month age without any significant variation. The present study revealed safe and effective means of replacing 50 per cent concentrate feed with in M. oleifera leaves in Malabari doelings in advancing puberty without affecting the growth performance.

Published: January 2023

Early detection of uterine inertia is very crucial for the life of the foetus as well as that of the dam. Suitable methods for early detection of uterine inertia are lacking in canines compared to humans.Non-invasivetocodynamometry is a promising method, which is widely used in humans for the management of uterine inertia.In the present study non-invasive uterine contraction monitoring using the tocodynamometry was performed in dogs with Complete Primary Uterine Inertia (CPUI) and Partial Primary Uterine Inertia (PPUI), as well as in control animals with the Foetal Cause of Dystocia (FCD).In all the dogs belonging to CPUI and PPUI, the contractions were mild and infrequent with force near to the baseline, i.e., less than 15 mm of Hg. There were no reflex contractions in response to the feathering of the vaginal wall in a majority of dogs belonging to these two groups. In the FCD group, there were strong and frequent contractions lasting for two to three minutes with contraction force above 15mm of Hg, reaching up to 30-40 mm of Hg. Those dogs with less than 15 mm of Hg pressure and feeble or infrequent contractions without delivery for more than 30 min, could be considered as uterine inertia and suitable therapeutic options could be considered judiciously. Tocodynamometry was found to be an effective tool for the early detection of uterine inertia,whichhelped arriving at a quick judicious decision which is pertinent for better foetal and maternal survival.

Published: January 2023

Bordetella bronchiseptica is a gram–negative bacterium with a broad host range that is most commonly seen in animals kept in close quarters. It is considered to be one of the main causes of the canine infectious respiratory disease complex (CIRDC). In this study, 45 dogs with clinical signs suggestive of CIRDC were selected and nasal/ oropharyngeal swabs were collected aseptically. Total DNA was extracted from the swabs and subjected to polymerase chain reaction (PCR) targeting alc gene of Bordetella spp. for confirmation. Nine animals (20 per cent) tested positive for the presence of Bordetella antigen. All the dogs tested positive for Bordetellosis were less than one year of age. Most common clinical signs in positive dogs were cough and nasal discharge, and the majority of the bordetellosis positive dogs were from multiple dog houses.

Published: January 2023

Postpartum diseases of uterus represent a foremost predicament in cattle farms affecting reproductive efficiency. Postpartum (PP) uterine diseases include metritis, endometritis and subclinical endometritis (SCE). Barring SCE, all other diseases project the clinical signs. Diagnosis of SCE at the early stage of PP has been a challenging task for many veterinarians. The present study aimed to validate and correlate the proficiency of transitional changes in uterus and cervix assessed by transrectal ultrasonography (TRUS) and endometrial cytology (EC) in the diagnosis of SCE in PP cattle. The research was carried out in two phases i.e, 30th day postpartum (DPP) (n=74) and first exhibited oestrus after 45th DPP (n=24) (54.63 ± 1.13 d) to emphasise the proficiency of both the diagnostic modalities. Endometrial cytology could discriminate between cows positive and negative for SCE significantly at 30th DPP (20.54 ± 0.48 vs 5.55 ± 0.41). It was potent in diagnosing SCE after 45th DPP also, as a significant reduction in the per cent of PMN cells (20.54 ± 0.48 to 7.56 ± 0.32) was noticed. Uterine parameters assessed by TRUS like cervical and uterine diameter and endometrial thickness in both the phases of assessment did not correlate to the EC changes and also could not discriminate between SCE positive and negative animals. The results of the study signify that EC is efficacious in the diagnosis of SCE in cows, while TRUS is impractical as a sole diagnostic modality for SCE.

Published: January 2023

Doppler ultrasonography is relatively a new method for evaluation of the renal diseases in dogs. This study was conducted to evaluate the efficacy of renal resistive index (RRI) in diagnosis and prognosis of acute kidney injury (AKI) in dogs and to ascertain its correlationwith other renal parameters. Twenty-seven dogs with AKI along with ten clinically healthy dogs were evaluated. The aetiology of AKI was multifactorial which included viper snake envenomation, pyometra, Babesiagibsoni infection, canine parvo viral infection, Ehrlichiacanis infection, leptospiral infection, bone meal poisoning and tetracycline-induced nephrotoxicity. Dogs with AKI were characterized into five gradesas per the guidelines provided by International Renal Interest Society. Parameters such asblood urea nitrogen (BUN), creatinine, urine output, urine protein-creatinine (UPC) ratio and blood pressure were estimated. Both BUN and creatinine was significantly higher in affected dogs. Majority of the dogs with AKI were oliguric and had the presence of proteinuria, occult blood and leucocytes on urine dipstick examination. Urine Protein-Creatinine ratio was increased whereas no significant variation was noticed in blood pressure of dogs with AKI.B-mode ultrasonography of kidneys revealedrenomegaly, hyperechoic cortex, decreased cortico-medullary differentiation and loss of architecture in majority of the dogs with AKI. Renal resistive index was significantly increased inAKI and a positive correlation was established between RRI and serumcreatinine but not with UPC ratio, blood pressure and size of kidneys. Re-evaluation of RRIseven days post treatment showed considerablereduction. It wasconcludedthat an increase in RRIwas associated with severity of renal parenchymal injuryin AKI and reduction of RRI post-treatment indicated favorable prognosis.

Published: January 2023

The study was conducted to optimize the level of Black Soldier Fly Larvae (BSFL) incorporation in the abattoir sludge and food waste combination. The substrate for the study included a combination of 70 per cent abattoir sludge as the principal substrate (PS) and 30 per cent hostel food waste as the co-substrate (Co- S) for BSFL rearing. Experiments were carried out to fix the level of larval incorporation into 320 g of the substrate and to assess the nutritional qualities of the harvested prepupae. The BSFL were incorporated in four different levels in 320 g of substrate (T1: 150 mg larvae, T2: 450 mg larvae, T3:600 mg larvae and T4: 750 mg larvae). The efficiency of BSFL to feed on the substrate and get converted into biomass was evaluated for the treatment combinations. Among the different treatments, T1had significantly (p<0.001) higher mean prepupal weight and larval survivability. Hence the addition of 150 mg larvae to the 320 g of substrate was found to be optimum for BSFL biomass production.

Published: January 2023

Canine mammary neoplasms are naturally occurring non-homogenous group of tumours with many resemblances to human breast cancer. In female dogs mammary tumours are of great clinical relevance due to the high prevalence and mortality rate, which varies according to the histopathological classification and clinical stage. The aim of the study was to compare the ultrasonographic features of the normal mammary gland with benign and malignant mammary neoplasms in dogs, through assessed by B-mode and Doppler mode ultrasonography. Ultrasonographic examination of seven normal mammary glands along with six benign and 12 malignant mammary neoplasms were performed. Among the parameters evaluated by B-Mode ultrasonography, significant differences were found (p < 0.01) in the tumour margin and invasiveness of neoplasms, where malignant tumours were invasive with uncircumscribed margin. Significant difference was also found in the presence of posterior acoustic enhancement (p<0.05) between benign and malignant mammary neoplasms. Elevated peak systolic velocity of blood flow within the tumour vessels in malignant mammary neoplasm was the only feature assessed with Doppler mode having significant difference.

Published: January 2023

Leptospirosis is an economically important zoonotic bacterial disease of cattle with global distribution. The present study investigated the seroprevalence and distribution of leptospiral serovars in cattle population in Pananchery panchayat of Thrissur district, Kerala. From 52 apparently healthy dairy cattle, serum samples were collected in both pre-monsoon and postmonsoon seasons. All samples were subjected to microscopic agglutination test (MAT) against 13 serovars of Leptospira spp. Among the samples tested, 13 (25 per cent) samples in pre-monsoon and 19 (36.54 per cent) samples in post-monsoon were found to be positive. The predominant serovars detected in pre-monsoon were Hardjo (29.41 per cent) followed by Grippotyphosa (17.64 per cent), Bataviae and Pomona (11.76 per cent each). Similarly in post-monsoon, Hardjo (28.57 per cent) followed by Grippotyphosa (23.81 per cent), and Bataviae (19.05 per cent) were identified as the most common serovars. Higher seroprevalence of disease in apparently healthy cattle in post-monsoon compared to pre-monsoon indicate the influence of rainfall on occurrence of leptospirosis.

Oriental theileriosis is a major haemoprotozoan disease of cattle and causes huge economic losses to the farmers. Oxidative stress plays an important role in the development of anaemia and subsequent complications associated with theileriosis. The present study was conducted to assess oxidative stress and antioxidant status of cattle infected with Theileria orientalis. In the present study, 16 animals which were positive for theileriosis by blood smear examination were selected. Confirmation of oriental theileriosis was done with polymerase chain reaction (PCR). Assessment of oxidative stress and antioxidant status were done by measuring malondialdehyde (MDA) levels and reduced glutathione activity respectively. Both MDA levels and reduced glutathione activity did not indicate any significant difference in animals infected with T. orientalis from control animals.

Published: January 2023

Majority of breast and ovarian cancer treatment modalities are based on endocrine therapies like antiestrogens which are dependent on the hormone receptor status of tumours. Although BRCA1 is a major regulator of Estrogen Receptor (ER-α), BRCA1 mutations are largely limited to hereditary cases. Here, we show the role of NBR2 (neighbour of BRCA1) in regulating ER-α. We demonstrate a positive correlation between NBR2 & ESR1 in TCGA datasets. Further, the study revealed that shRNA-mediated knockdown of NBR2 led to the downregulation of ER-α in breast cancer cells, MCF7. Finally, the downregulation of ER-α in NBR2 knockdown xenograft tumours (in female NSG mice), which showed higher invasive properties than wild type tumours was demonstrated. Thus, we concluded that in ER-α negative tumours with NBR2 deficiency, biguanides such as metformin and phenformin, which are reported to have a better efficacy under NBR2 deficient conditions, could serve as more suitable alternatives to antiestrogens.

Authors: Bustamam Fitri Rostina Zaini , Hartini H
Published: January 2023

Due to the outbreak of COVID-19, learning institutions in Indonesia have been forced to switch to e-learning. E-learning is a new way of education that everyone had to adopt. To ensure the continuity of teaching and learning activities, higher education institutions (HEIs) need to explore ways to increase the quality of e-learning systems. The paper aims to understand the quality factors that influence e-learning adoption in Indonesia. The proposed framework is validated with 753 students from four universities located in different regions of Indonesia. Data were analysed using Statistical Package for the Social Sciences (SPSS) software. The findings show that a relationship does exist between information quality and e-learning adoption. However, system and service quality did not indicate any significant influence on e-learning adoption.

Giraffidae (Artiodactyla, Mammalia) from the Late Miocene of Kalimantsi and Hadjidimovo, Southwestern Bulgaria
Authors: Geraads Denis , Spassov Nikolai , Kovachev Dimitar
Published: January 2023

The various Late Miocene localities around the Bulgaria yielded a rich collection of giraffes, including Helladotherium duvernoyi, Bohlinia attica and Palaeotragus rouenii. These are the same species as at Pikermi, suggesting that there is no great age difference between these localities, but the limb-bones of both former species are stouter at Kalimantsi than in the Greek site, a difference which is perhaps of ecological origin. The absence of Samotherium, known in the geographically close sites of Greek Macedonia might be a consequence of the isolation of the river basins.
The Carboniferous of Svoge Coalfield (Bulgaria)
Authors:   Geological Institute, Bulgarian Academy of Sciences, 1113 Sofia, Tenchov Yanaki
Published: January 2023

The Svoge Coalfield Carboniferous is subdivided into Tsarichina Formation with Dalbochitsa Member (250 m – Namurian A), Svidnya Formation (220 m – Namurian C-Westphalian A), Dramsha Formation (180 m), Svoge Formation (500 m – Westphalian A), Berovdol Formation (280 m – Westphalian A-B) and Chibaovtsi Formation (420 m – Westphalian B-C). Except Dramsha Formation, that is built of claystones, the other formations consist mainly of sandstones, with few levels of claystones with or without coal seams. Conglomerates occur at the base of Tsarichina, Svidnya and Chibaovtsi Formation and are intercalated in the sequences of Svidnya, Svoge and Chibaovtsi Formation. The coal seams are superantracites (95—98% volatile) mainly thin, some are 0.6 to 2.0 m, but in place reach even 12 m most frequently in result of tectonic accumulation. Breaks in sedimentation are between Tsarichina and Svidnya Formation and at the base of Berovdol Formation. The basement is built of a continuous Ordovician, Silurian and Devonian sequence covered with erosive contact and angular (up to 30°) unconformity by the Carboniferous. The folded (in normal and reversed folds) Palaeozoic section is unconformably covered in the western part of the coalfield by Lower Triassic. Tectonically the Coalfield is a complex graben superimposed on the core of the Alpine Svoge anticline. The south parts are built of symmetric folds. The north parts are of recumbent folds which in the east half are north vergent, whereas in the west part are south vergent, being separated by a prominent wrench fault. The south part is folded in pre-Permian time, possibly during the Leonian Phase, when the sedimentation stopped, and the graben has been transformed in a horst structure, maybe during the Asturian Phase. Both parts are refolded during an Alpine (Late-Cretaceous) north-vergent folding. The western south vergent folds are separated from the Triassic cover by decollement whereas most probably the Svidnya Pluton has resisted to the north directed pressure.

Published: January 2023

Disinfection of various surfaces is used everywhere in different areas of human activity. Disinfection of surfaces has gained particular relevance in recent years. However, in the process of disinfection, solutions with high concentrations of active substances are used. The most common substances used for disinfection are those containing chlorine. Among them, sodium hypochlorites, calcium hypochlorites, and bleach are most commonly used. In the process of surface dis-infection, the materials of the treated surfaces are destroyed. This can lead not only to the migration of leached-out metals but also to the destruction of materials and structures. As an alternative disinfectant, the article considers ozone solutions in water. Ozone has found widespread use for water disinfection, but it has not found wide application for surface disinfec-tion. The article investigated the corrosive effect of disinfectants on carbon steels St3 and 08. For research, chlorine-containing solutions were used at a concentration of 2 wt.% in terms of hypochlorite ion and ozone-saturated water as an alternative disinfectant solution. The research results showed that chlorine-containing solutions have the greatest corrosive effect on the studied stainless steels, among which the sodium hypochlorite solution has the greatest corrosive effect. The use of ozone-saturated water is characterized by the lowest values of corrosion currents.
A Study on Blade Production Technique of Imsil Haga Paleolithic site
Authors:   한국구석기학회, Jeong Bohyun
Published: January 2023

The blade is a representative artifact of the upper Paleolithic of Korea. The study of the manufacturing techniques of the blade and restoration of it play an important role in understanding of survival skills of upper Paleolithic human. This paper researches into the technology and process of the blade production through the blade production technology we learned from ‘Refitting artifact’ of Imsil Haga site, and analogizes the kind of the hammer which they used for the blade production in comparison with the existing research result of experimental archaeology on the blade production. Restoring the blade production process as a result of the analysis of ‘refitting artifacts’, 1. Shaping, removed cortical face and unnecessary parts of the raw material are made into sizes and shapes suitable for blade production using stone hammer direct percussion (refitting artifacts 1, 3). 2. creation of a striking platform, 3. blade debitage using the Antler hammer direct percussion. (refitting artifacts 1, 3) 4. Change the striking platform according to the production process, and blade debitage by making the most of the stones several times (refitting artifacts 1, 2). 5. When knapping accidents (step, hinge, and flange) appeared on the blade core, or when the size of the core became smaller and it became difficult to make a blade of the desired size, the blade was discarded without production more blades. The reason for the abandonment of the blade was 1. If it is no longer possible to make the blade due to the Knapping accidents (step, plunging, hinged), 2. If the size of the blade cannot be made, The ‘Refitting artifact 1’ includes two tools (tanged point), which analyzed the length and production space of the tool that the tool maker wanted. First of all, considering that the length of the blade identified in ‘Refitting artifact 1’ is about 40 to 88mm, and the tanged point is about 51, 54mm, it is thought that the stone maker made a blade with a length of about 50 to 70mm or made a tool. The excavation location of tanged point is about 2m away from the central part of the bladecore, and it is thought that the tool was made by moving the blade after manufacturing it.

Type of Cell Separator, Fenwal Amicus Vs COBE Spectra LRS, May Influence the Corpuscular Elements Value of the Donor`s Blood (SN-ICFC Procedure)
Authors: Landzo Elvedin , Bajraktarevic Adnan , Cetkovic Vesna
Published: January 2023

Background: During the plateletpheresis procedure the number of thrombocytes in the donor’s blood significantly decreases, and the levels of the hematocrit, hemoglobin, and leukocyte diminish as well. Influence of the cell separator is one of the factors that affects the levels of HCT, Hgb and WBC. Objective: In this study, the goal was to determine the value difference of HCT, Hgb, WBC, and platelets after the platelet pheresis process between performance on Fenwal AMICUS and on COBE Spectra LRS Methods: The criteria for participation: male in the age range of 25-45. We have formed two groups: group I–180 separation were performed on 60 participants were the values of hematocrits, concentration of hemoglobin and number of leukocytes ware established before and after separation using the single-needle intermitent flow cell separation (SN-IFCS) on the Fenwal AMICUS device. Group II – presented 180 separation that were performed on 60 participants, were the values of hematocrits, concentration of hemoglobin and number of leukocytes ware established before and after separation using double-needle continuous flow cell separation (SN-IFCS) on the COBE Spectra LRS. device. To confirm the statistical differences we have used Student t-test for independent or dependent samples, as well as Mann-Whitney U test as non-parametric alternative. To compare differences between the values of four parameters (P1-P2) from two groups (using two devices–Fenwal AMICUS and Fresenius Com Tec) we have performed the ANOVA variance analyze. The possibility of errors were accepted for α<0,05, and the difference between groups as statistical relevant were accepted for p<0,05. Results Statistically significant lower values were noted for all researched parameters after separation on both devices (Fenwal AMICUS and COBE Spectra LRS). Comparing the parameters of hematocrit, leukocytes and hemoglobin’s, we found a statistical significant difference in the decrease of the parameter’s value after separation, there was a significant decrease change in using COBE Spectra LRS cell separator compared to using Fenwal AMICUS cell separator with the same procedure. For the platelets (Plt) there was no statistical significant difference (p> 0,05-α=0,05), between average level obtained using either Fenwal AMICUS or COBE Spectra LRS. Conclusion: The type of cell separator had the influence on the decrease value of the observed parameters.

Published: January 2023

Background: Objective Structured Practical Examination (OSPE) is globally implemented and beneficial system that is utilized for assessing students in practical examination. It is used to assess the competency based on objective testing through direct observation. It comprised several “Stations,” in which examinees are expected to perform variety of practical tasks within specified time period against criteria formulated to practical skill, thus demonstrating competency of skills or attitude. OSPE is very useful to evaluate their ability to obtain or interpret data, solve the problem, teach, and communicate.

Aims and Objectives: The primary objective is to obtain student’s perception toward OSPE and study the effectiveness of OSPE as a tool for summative assessment also quality care assurance of OSPE.

Materials and Methods: The study was carried out in January 2022 at our institute. A total 197 students were enrolled after obtaining verbal consent for summative assessment (University Exam). The assessment was carried out for 4 days with different batches per day. Each student attended six different OSPE stations. Data collection was done using a structured questionnaire from students. Perception of students was assessed on the basis of 5-point Likert-scale.

Results: Majority of students (82%) agreed that the sequence of stations was appropriate. For instance, they also agreed (82%) that time allotted at stations was adequate. Regarding examination environment, 83% of students agree that it was appropriate for the conduct of exam. Majority (79%) number of students agreed that OSPE helps to evaluate wide range of knowledge. About 81% of students felt that stations covered major competencies.

Conclusion: Although OSPE is a laborious and time intensive assessment tool, the present study showed several advantages of OSPE as a structural, organized, and fair assessment method for summative assessment.

Published: January 2023

In Eagle syndrome, elongated styloid processes may provoke internal carotid dissection and pseudoaneurysm causing stroke and data regarding possible complications or long-term results of pseudoaneurysm treatment using a flow diverter are limited. We report a case of a dissection-related pseudoaneurysm in the left cervical carotid artery treated by implantation of a flow diverter. Follow-up imaging of the flow diverter showed fracture of a continuous radiopaque marker at 3 months and fracture of a second continuous radiopaque marker at 7 months, while contrasting of the vessel was preserved. At the time of angiographic control (8 months after implantation), the flow diverter and the extracranial left internal carotid artery were occluded, and the patient did not experience any symptoms throughout the period.
