Lamb head as a training model for septoplasty and rhinoplasty

Background: Septoplasty and rhinoplasty are difficult operations to learn and teach. Many modalities have been proposed to make the teaching process of these operations easier. In this study, it was investigated if lamb heads were good training models to teach septoplasty and rhinoplasty to trainees or experienced surgeons. Methods: In the first part of the study, 21 lamb heads were dissected according to a dissection protocol and several anatomical distances were measured in order to compare them with human cadavers. In the second project 8 lamb heads were dissected and different preservation rhinoplasty techniques were practiced. Results: The study on 21 lamb heads used showed that the lateral crura were 17.8 x 11.6, average interdomal distance was 8.1 mm, average domal width was 3.7 mm. The average length of the upper lateral cartilages was 31.1 mm laterally and 21.2 medially. The average length of the nasal bones was 63.9 mm and the width was 16 mm. In the second part of the study 8 lamb heads were used to experience where high strip techniques were used in 5 and Cottle technique in 3. Conclusion: This study revealed that lamb head should be considered as an excellent training model for septoplasty and rhinoplasty. Its very low cost, ease of availability, and close similarity to the human cadavers can be counted as the main advantages. This study also proved that it was not only a tool for beginners, but also a very helpful tool for experienced surgeons to try new methods.

An Intriguing New Species of Sanchezia (Acanthaceae) from Southeastern Peru

Abstract— Sanchezia dubia is described and illustrated as a new species from the department of Madre de Dios in southeastern Peru. Its morphology slightly resembles Sanchezia sprucei, but its most remarkable feature is its close similarity to Suessenguthia, even more so than to those of its own genus. This new species is distinguished from others by its glabrous stem and leaves, its inflorescence containing two to five serial cymose heads, which are sessile to short-pedunculate, with mostly two to four flowers each (occasionally one), its inner bracts ranging in length between 6 and 23 mm, and its androecium composed of two stamens and two mucronate staminodes. We suggest it is an endangered species based on its restricted geographic distribution, its few known populations, and the increasing threats to its habitats. Along with Suessenguthia koessleri, this new species seems to be a key taxon to understanding the phylogenetic relationship between these two genera, which is still uncertain. Additionally, we provide a key to identify the Sanchezia and Suessenguthia species of the Madre de Dios River basin from southern Peru to northern Bolivia.

Assessing the Accuracy of Fault Interpretation using Machine Learning Techniques when Risking Faults for CO2 Storage Site Assessment

Generating an accurate model of the subsurface for the purpose of assessing the feasibility of a CO2 storage site is crucial. In particular, how faults are interpreted is likely to influence the predicted capacity and integrity of the reservoir; whether this is through identifying high risk areas along the fault, where fluid is likely to flow across the fault, or by assessing the reactivation potential of the fault with increased pressure, causing fluid to flow up the fault. New technologies allow users to interpret faults effortlessly, and in much quicker time, utilizing methods such as Deep Learning. These Deep Learning techniques use knowledge from Neural Networks to allow end-users to compute areas where faults are likely to occur. Although these new technologies may be attractive due to reduced interpretation time, it is important to understand the inherent uncertainties in their ability to predict accurate fault geometries. Here, we compare Deep Learning fault interpretation versus manual fault interpretation, and can see distinct differences to those faults where significant ambiguity exists due to poor seismic resolution at the fault; we observe an increased irregularity when Deep Learning methods are used over conventional manual interpretation. This can result in significant differences between the resulting analyses, such as fault reactivation potential. Conversely, we observe that well-imaged faults show a close similarity between the resulting fault surfaces when both Deep Learning and manual fault interpretation methods are employed, and hence we also observe a close similarity between any attributes and fault analyses made.

Between Sanudo and Fedanzola: Ashtori Ha-Parḥi as Mediator

This essay will examine the close similarity between the treatises of a Franciscan monk named Giovanni di Fedanzola and a Jewish sage named Ashtori Ha-Parḥi in the fourteenth-century Holy Land. The absence of guides for Christian pilgrims after the final departure of the Crusaders in 1291 was filled inter alia by Jews, and some new traditions regarding toponyms and geographical identifications were adopted by Christians as a result. Fedanzola mostly relied on his predecessors Burchardus de Monte Sion and Marino Sanudo. However, I will demonstrate that there are some instances where Fedanzola accepts Jewish traditions regarding locations mentioned in the Old Testament, with Ashtori Ha-Parḥi as his source. I will also show that positing a relationship between the two can clarify some obscure passages in Ashtori’s treatise, Kaftor va-feraḥ.

Исходя из анализа физико-механических свойств раствора для каменной кладки стен объектов культурного наследия рекомендованы три состава. The article provides an overview of the developed organic-inorganic compositions of masonry solutions for the walls of ancient tower and necropolis structures of the Chechen Republic and the Republic of Ingushetia. The prospects of the practical application of organic-inorganic binders for the repair and restoration of historical and cultural monuments are noted, due to the close similarity of the developed compositions to the "mother", due to which they are more effective and contribute to improving the quality and durability. Based on the analysis of the physical and mechanical properties of the mortar for the masonry of the walls of cultural heritage objects, three compositions are recommended.

CONCEPT OF UDAVARTA (PRIMARY/SPASMODIC DYSMENORRHOEA) – AN AYURVEDIC PERSPECTIVE

Many women are familiar with the experience of spasmodic dysmenorrhoea, one of the commonest gynaecological conditions that affects the quality of life of many in their reproductive years.This condition manifested as painful menstruation, is the most frequently encountered gynaecological complaint and it can be included under Udavartha yonivyapat, caused by Apana vata vaigunya described in Ayurvedic classics. Nidana samprapthi and Rupa of Udavartha yonivyapat can well explain the etiopathogenesis and clinical features of Spasmodic dysmenorrhoea. “Arthave sa vimukthe tu tat kshanam labhate sukham” mentioned by Acharya Charaka substantiate the close similarity of Udavarta with Spasmodic dysmenorrhoea. Vegodavarthana leading to Pratiloma gati of Apana vata and rajas is the pathology behind Udavartha yonivyapath. So treatment should aim at the relief of pain by normalising the direction of menstrual flow which in turn is by normalising the vitiated Apana vayu. The present paper is aimed at incorporating all the references regarding Udavartha including Nidana panchakas from Ayurvedic classics and tried to give an Ayurvedic view to the concept and postulated theories on spasmodic dysmenorrhoea.

From Hector Mine M7.1 to Ridgecrest M7.1 Earthquake. A Look from a 20-Year Perspective

The paper provides a comparative analysis of precursory phenomena in the ionosphere and atmosphere for two strong earthquakes of the same magnitude M7.1 that happened in the same region (North-East from Los Angeles) within a time span of 20 years, the Hector Mine and Ridgecrest earthquakes. Regardless of the similarity of their location (South-Eastern California, near 160 km one from another), there was one essential difference: the Hector Mine earthquake happened during geomagnetically disturbed conditions (essential in the sense of ionospheric precursors identification). In contrast, the quiet geomagnetic conditions characterized the period around the time of the Ridgecrest earthquake. The Hector mine earthquake happened in the middle of the rising phase of the 23-rd solar cycle characterized by high solar activity, while the Ridgecrest earthquake happened by the very end of the 24th cycle under very low solar activity conditions. We provide a comprehensive multi-factor analysis, determine the precursory period for both earthquakes and demonstrate the close similarity of ionospheric precursors. Unlike the majority of papers dealing with earthquake precursor identification based on the “abnormality” of observed time-series mainly determined by amplitude difference between “normal” (usually climatic) behavior and “abnormal” behavior with amplitudes exceeding some pre-established threshold, we used the technique of cognitive recognition of the precursors based on the physical mechanisms of their generation and the morphology of their behavior during the precursory period. These permits to uniquely identify precursors even in conditions of disturbed environment as it was around the time of the Hector Mine earthquake. We demonstrate the close similarity of precursors’ development for both events. The leading time of precursor appearance for the same region and similar magnitude was identical. For the Hector Mine it was 11 October 1999—5 days in advance—and for 2019 Ridgecrest it was 28 June—7 days before the mainshock and five days before the strongest foreshock.

RELEVANCE OF LASUNA RASAYANA IN THE MANAGEMENT OF OPHTHALMIC NEURALGIA WITH RESPECT TO VATAPARYAYA- A CASE REPORT

Trigeminal neuralgia, otherwise known as suicidal disease is the severe and recurrent pain in the distribution of one or more branches of Trigeminal nerve. Patient usually presents with sharp electric shock like pain in face or mouth which lasts for seconds to minutes. This condition may lead the patient to a stage of depression and suicidal tendency. In ophthalmic neuralgia V1 branch of trigeminal nerve is affected where the pain can be interpreted as coming from nose, eyes and head in the areas around the scalp. The management involves anticonvulsants, antidepressants and surgical procedures. Vathaparyaya described by Acharyas shows a close similarity with ophthalmic neuralgia in which vitiated Vata causes pain in the areas of eyelashes and eyebrows. The management of Vataparya is given as same as that of the Vatabhishyanda. In present study, it is observed that Ayurvedic management has provided a significant reduction in intensity and frequency of pain.

Online learning: Students’ autonomy and attitudes

This study aims at investigating students’ autonomy and attitude in learning TOEFL online which the program was organized by the Language Centre, Department of Education and Culture, West Nusa Tenggara during the pandemic Covid-19. A set of questionnaires was distributed to 134 students that came from a different geographical location in West Nusa Tenggara province, and were different in age. The participants in the present study were all who had been announced officially as the TOEFL course awardees for Mataram area. The findings indicated that albeit positive tenets on students’ autonomy and attitude. The results showed very close similarity as described by 2% difference in mean scores between students’ autonomy and attitude. The poor category results were found from students’ inability to evaluate their strength and weakness in learning autonomously and the students found it was hard to keep make correspondence immediately with teachers. This study ends with suggestions for the next TOEFL course programs
