Metastability of Protein Solution Structures in the Absence of Solvent: Rugged Energy Landscape and Glass-Like Behavior
Authors: Cropley Tyler C. , Liu Fanny C. , Chai Mengqi , Bush Matthew F. , Bleiholder Christian
Published: November 2023

Despite the significance of differentially modified proteins (proteoforms) to human health, it remains challenging to identify how proteoforms alter protein structural dynamics and function. Although native ion mobility/mass spectrometry is well-suited to handle proteoform heterogeneity, it characterizes protein structures in the absence of solvent. This raises long-standing, unanswered questions about the biological significance of structures identified through ion mobility/mass spectrometry. Using newly developed computational and experimental ion mobility/ion mobility/mass spectrometry methods, we investigate the structural denaturation of the protein ubiquitin in the solvent-free environment. We show that ubiquitin exists in the absence of solvent as an ensemble of kinetically stable subpopulations that are separated by substantial free energy barriers. These subpopulations unfold but do not interconvert, which indicates that the solvent-free subpopulations originate from different solution-phase conformations. The subpopulations exhibit stretched-exponential denaturation kinetics consistent with a glass transition associated with separating the C-terminal beta-strand from the N-terminal beta-hairpin occurring on the folded side of the unfolding transition state. Our data indicate that this transition state is highly polarized with significant native content in the N-terminal beta-hairpin and alpha-helix, resembling the transition state reported for the presence of a solvent. Taken together, our analysis suggests that ubiquitin in the solvent-free environment reflects the conformational ensemble of ubiquitin in solution because the initially formed solvent-free state of ubiquitin appears glass-like and “melts” over several seconds.

Published: November 2023

Materials science research is a multifaceted field, with valuable data scattered across the pages of research papers in various formats. The efficient extraction of data from these papers is of paramount importance for further analysis and research. This study aims to shed light on the distribution of data in materials science papers and their interconnections. In this preliminary analysis, we systematically examined 10 random materials science papers to discern where key data types—composition, processing conditions, characterization, and performance properties—reside within the textual content, tables, and figures. Our findings reveal intriguing patterns in the presentation of data, ranging from conventional text-based descriptions to detailed tabular presentations and visually informative figures. The analysis encompasses diverse materials and highlights cases where data types are isolated or interconnected across different sources. We also address the challenges and limitations faced during the annotation process. This investigation underscores the importance of understanding data distribution within materials science papers, as it has profound implications for data accessibility and integration in the field. Furthermore, these insights pave the way for future research, particularly in the development of advanced NLP models tailored to the unique characteristics of materials science research papers and other machine learning techniques for more efficient data extraction and analysis in materials science research.
The rupture plane of the February 2022 Mw 6.2 Guatemala, intermediate depth earthquake
Authors: Yani-Quiyuch Robin , Asturias Ludwing , Castro Diego
Published: November 2023

An intermediate depth intraplate earthquake with Mw 6.2 was generated in the Guatemalan subduction zone on 16 February 2022 with epicenter to Southwest of the department of Escuintla. More than 275 aftershocks were registered, which were relocated with the HypoDD algorithm, being able to identify a fault with an area of ~350 km2, which is considerably higher than expected for an earthquake of that magnitude. The moment tensor at the centroid of the main earthquake and the estimation of other focal mechanisms of the largest aftershocks, allowed us to identify extension earthquakes, related to the fault plane, and compression earthquakes that were associated with seismicity on the upper part of the slab. The region of the sequence has presented high seismic activity in recent years. It is proposed that the mainshock nucleated in the lower seismicity layer (LSL) of the double seismicity zone proposed for the region, triggering seismic activity on a pre-existing active fault, also triggering seismic activity in the upper seismicity layer (USL). The separation between these seismicity layers was estimated to be 12.2±5.0 km.

Published: November 2023

An ethno medicinal survey was carried out to gather information about medicinal plants utilized by Irulas and Kurumba tribal people in the Burliyar taluk. About 50 medicinal plants species belonging to 34 families used by the tribal people for the treatment of Asthma, Burns, Diarrhea, Fertility, Fever, Jaundice, Kidney stone, Malaria, Snake bites, Wounds etc. has been identified and collected. The most representative families are Asteraceae and Solanaceae with 5 species each. The plants were found to be used in different forms such as juice, extracts, paste, powder, infusion. These ethno medicinal plants were used to treat ailments like cold, cough, headache, stomach ache, dysentery, skin diseases, poison bites, cuts and wounds and diabetes.
Modeling of laminar flows of nanofluids between two coaxial cylinders in microfluidic devices
Authors: Kurkchi Yelizavieta , Kizilova Nataliya
Published: November 2023

The laminar flow of three immiscible nanofluids between two coaxial cylinders due to a constant pressure drop at the inlet and outlet of the channel is considered. Experimental studies of the flows of different nanofluids through the tubes and channels of microfluidic devices have shown that the measured relationships between the pressure drop and volumetric flow do not correspond to the calculations of the corresponding Poiseuille flows in the same geometry due to tangential momentum transfer during diffuse scattering of nanoparticles on the wall roughness. When the characteristic roughness scale has the same order as the particle size, the scattering becomes significant in both dilute gases and suspensions of nanoparticles. Accordingly, the solution of the problem was obtained with the second order velocity slip boundary conditions at the rough walls. The presence of wall layers with a constant thickness and different viscosities is associated with the repulsion of the nanoparticles from the walls into the core of the flow. At the interfaces between the layers, the continuity conditions for velocities and tangential stresses were accepted. An analytical solution of the system for pressure and velocities of the fluids is obtained. Expressions for volumetric flow and wall stresses are calculated. It is shown that for some sets of model parameters it is possible to obtain a significant increase in the flow rate and decrease in viscous dissipation due to tangential momentum transfer at the walls. The effect could increase the efficiency of various microfluidic systems. The formula for the capillary viscometer in the case of measuring the viscosity of nanofluids was also obtained. The derived analytical solution can be used for validation of numerical codes for more complex flows (transient, turbulent) in similar geometries.

New insights into ancestry and health of Polynesians and New Zealand Māori
Authors: Chambers Geoffrey , Edinur Hisham , Dunn Paul
Published: November 2023

We are now moving towards the new era of personalised medicine. In prospect, a DNA-tailored healthcare system will utilise genomic information from patients and populations for the prevention and treatment of diseases. This near-future medicine recognises that there is already evidence of genetic disparity between people of different ethnicity. Our own previous genetic surveys of human genomes have demonstrated abundant genetic variation in New Zealanders. These now include extensive new work on immune system genes. We have produced a comprehensive reference set of genotypes for clinically relevant antigens in transplantation (human leukocyte antigen, major histocompatibility complex class I chain-related gene A and killer cell immunoglobulin-like receptor) and transfusion (blood group and human platelet antigens) medicine in Māori and Polynesians. This report sets these data in context and highlights allelic variations and their implications for ancestry and health. It is hoped that this information may help to resolve some of the present inequalities in Māori and Pacific health status.

If only I had time: Teachers’ perceptions of teaching high-ability science students
Authors: Horsley Jenny , Moeed Azra
Published: November 2023

​With many countries relying on science and technology for their economic prosperity, science educators are tasked with nurturing curiosity and encouraging high-ability science students to become creative and innovative scientists of the future. This exploratory case study employed semi-structured interviews to investigate how four award-winning science teachers identified and addressed the learning needs of their high-ability science students. The research was underpinned by a constructivist theory of learning. Findings suggest that these teachers were not aware of mandated policies for Gifted and Talented students. They used English and mathematics standardised tests for identifying high-ability science students, supplemented with their own approaches to identification. Although literature identifies the importance of student-led science inquiry, we found no evidence of the teachers engaging their students in authentic scientific inquiry to enable them to investigate their own questions. These findings are discussed in the light of extant literature. Keywords: high-ability science students; gifted and talented in science; identification of high-ability science students

Published: November 2023

Introducción: El suicidio es un creciente problema de salud pública. Este estudio tiene como objetivo analizar la ideación, planificación y/o conducta suicida en relación a factores sociodemográficos, estado de salud mental y uso de redes sociales. Se comparó un grupo de personas con conducta suicida con otro grupo sin conducta suicida, emparejados por sexo y edad.
Metodología: Se realizó un estudio descriptivo longitudinal comparativo. La variable de resultado fue la conducta suicida. Se recopilaron datos sobre variables sociodemográficas, salud mental y uso de redes sociales. Se utilizaron los estadísticos chi-cuadrado y T de student y se llevó a cabo un análisis de regresión logística multivariante.
Resultados:   Se contó con la participación de 102 sujetos, 51 de ellos con ideación o intento suicida, y 51 de ellos sin ideación suicida en el último año. Se encontraron diferencias significativas entre estos grupos en cuanto a variables sociodemográficas e historial de diagnósticos psiquiátricos. Según el análisis multivariante, los factores asociados con la conducta autolítica incluyen no estar trabajando (estudiar, desempleo, jubilado, o con incapacidad temporal o permanente) (B: 1,193, Odds ratio: 3,298), haber presentado un episodio depresivo el año anterior (B: -2,350, Odds ratio: 0,095), y haber experimentado un trastorno de ansiedad (B: -1,659, Odds ratio: 0,190). El modelo muestra una Rcuadrado de Cox y Snell de 0,418.
Conclusiones: Estos resultados confirman la existencia de un perfil de personas en riesgo de conducta suicida. El uso diferencial de redes sociales puede servir para la evaluación ecológica instantánea de riesgo.
El papel de la negociación colectiva en la regulación del teletrabajo: nuevos retos de actuación
Authors: Sierra Hernaiz Elisa
Published: November 2023

La negociación colectiva tiene un papel fundamental a la hora de regular y adaptar cuestiones clave del teletrabajo como es la prevención de riesgos laborales específicamente adaptada a esta modalidad de prestación de servicios; los derechos de desconexión digital; los derechos de conciliación laboral y familiar con perspectiva de género o el acoso virtual o ciberacoso. Sin embargo, hasta el momento, se ha centrado principalmente en fijar aspectos de tipo formal o de contenido material sin tener en cuenta en la mayoría de los convenios colectivos las peculiaridades que el teletrabajo presente en esas cuatro materias, lo que puede suponer crear nuevos focos de desigualdad o dar lugar a nuevos riesgos laborales
El giro performativo en poesía: perspectivas teóricas y nuevos lenguajes
Authors: González Gil Isabel
Published: November 2023

La performatividad se ha convertido en una de las principales categorías para entender la contemporaneidad literaria, también en lo que concierne a los lenguajes poéticos. Sin embargo, las aportaciones teóricas al respecto vienen de ámbitos diversos y no siempre conciliables. Teorías de la performance como las de Schechner (1977), Phelan (1993) o Fischer-Lichte (2004) permiten abordar prácticas poéticas que surgen en territorios híbridos entre la poesía, la escena, el arte de vanguardia o la neo-oralidad tecnológica, por ejemplo, la perfopoesía, la poesía sonora, las acciones poéticas o el slam poetry, y que comparten rasgos de esta, como la importancia del acontecimiento frente a la representación, la inscripción semiótica del cuerpo o la co-presencia y el regreso a la comunidad. Por otro lado, teorías de la lírica, como la de Jonathan Culler (2015), han llamado la atención sobre los aspectos de performance del poema (repetición, ritmo, metro, rima, etc.). Este artículo explora estas aportaciones teóricas, diferenciando tres ejes: poesía performativa; teorías sobre la performatividad del poema y construcción de posturas e identidades autoriales, examinando qué códigos son específicos de la lírica y en qué medida puede hablarse de un “giro performativo” en poesía.

RECENT TRENDS IN NEAR-SURFACE AIR TEMPERATURE IN ANTARCTICA FROM REANALYSYS AND STATION DATA
Authors: Romanov P. Yu. , Romanova N. A.
Published: November 2023

This study utilizes monthly-mean records of near-surface air temperature from ground-based stations in Antarctica spanning the time period of 1980 to 2022 to estimate temperature trends in the region. Analysis of in situ data confirms the prevailing warming tendencies over the continent, with positive trends observed at 11 out of the 18 examined stations. Annual mean temperature trends reach 0.40 °C/decade, with the most significant warming observed in the Antarctic Peninsula, West Antarctica, and Inner Antarctica. Relatively weaker and mixed temperature trends occurred in the coastal areas of East Antarctica. Throughout the year, the spring season exhibited the most consistent upward trends across the continent. Comparing current temperature trends with earlier estimates has revealed increased warming at most Antarctic stations in recent years. Four widely used reanalysis datasets – ERA5, JRA55, MERRA2, and CFSR – were examined to evaluate their ability to reproduce the observed temperature trends in situ. Among these four datasets temperature trends inferred from ERA5 provided the best fit to the station data. However, even in ERA5, the uncertainty in trend estimates was comparable to the magnitude of trend variation between stations. This suggests a limited ability of available reanalysis datasets to accurately reproduce the spatial distribution and patterns of temperature trends across the continent.

Preliminary Observations on the Insect-free Storage of Grains.
Authors:   Assitant Entomologist,Agricultural Reserch Institute, Coimbatore  641 003, T.V SUBRAMANIAM
Published: November 2023

The successful storage of his grains free from insects is a serious problem for the ryot. The grains have to be stored for some time, longer or shorter, before a ryot can dispose them off for food or for seed and during this period they are liable to be spoiled in various ways: their suitability for food may deteriorate or they may suffer in their germi nating capacity; and insects contribute largely to this damage, the loss from which may amount to several lakhs of rupees in a year. It has been calculated that cholam (sorghum) grains alone are liable to damage upto 25 per cent during the course of storage for a year; in very bad cases it may be more. According to the Season and Crop Report for the year 1938-39 published by the Madras Government 1,265,300 tons of cholam were produced in this Presidency in that year, valued at Rs. 94,867,500. At a low estimate of 10 per cent the loss due to insects would come to 9 millions of rupees. This loss has been calculated to be caused by only one species of insect the rice weevil. If we take into consideration also other insects that take their toll, we can easily imagine, how great the loss caused to cholam grains in our presidency would be due to insects. Insects attack- ing grains are many; this paper deals with observations regarding only two of these, viz, the rice weevil on cholam and the paddy-borer beetle on paddy. The rice weevil, though commonly so called, is more a serious pest of cholam grains here than of paddy.
Soil Frosion: The Growth of the Desert in Africa and Elsewhere
Authors:   Tamil Nadu Agricultural University Coimbatore  641 003, HALL SIR DANIEL
Published: November 2023

It is a commonplace of geology that the surface of the earth is constantly in motion; that our mountain ranges have taken shape and our river courses and valleys have been excavated by rain, frost and wind. In many parts of the world this movement of the soil surface is taking place rapidly, with serious consequen- ces to the agriculture of those countries, owing to soil erosion. 1 The soil is dependent for its stability on its normal covering of vegetation, but as a rule the soil proper is not more than 6 inches to a foot deep, and it is in the surface layer that the fertility resides. There is thus always a danger that if the cover of vegetation is removed, the soil itself may shift under the action of either wind or rain. The earliest cases of erosion caused by such movement of the soil are those which follow deforestation in regions where the mountains in which the rivers take their rise are below the permanent snow line-e.g., in the eastern Mediterranean. There is no evidence in support of the belief that forests increase the rainfall of a country; indeed, by the transpiration from their leaves, they must reduce the total amount of the rainfall retained by the soil, but they serve as its regulator; as the rain falls, it is absorbed by the spongy soil below the trees, rich in humus, and reappears later in the springs and rivers when the rainy season is over. Too commonly, however, the forests have been cut down without regard to their regeneration, both for the value of their timber and for u desire to extend the grazing land.

In three previous papers many evidences were adduced proving the homology between stigmas and awns in sorghum. In the third paper the occurrence of basal feathered stigmas was recorded and also the fact that along with such occurrence and the presence of awns, the barbs of the subular portion of the awn were also basal in occurrence. The stigmas in sorghum are generally fully feathery (Fig. 1.). The length and disposition of the feathers may vary between varieties. The experience in the suppression of the feathers in the top portion of the usually feathery area of the stigma was met with in 26 sorghum varieties from Central and East Africa, i.e., N. Rhodesia, Nyasaland, Tanganyika and Kenya territories. These sorghums belong chiefly to the groups S. conspicuum Snowden and S. Roxburghii Stapf, groups characterised by gaping glumes. In these varieties the stigmatic portion is feathery at the base only with a bare cylindrical projection at the top (Fig. 2). The length of the feathery area varies from one-third to two-thirds the length of the stigma and is constant within the variety. To the naked eye, the non-feathery portion of the stigma appears smooth. Under the microscope, there are seen incipient projections, connoting suppressed feathers (Fig 4.). Stray feathery out- growths can occasionally be seen in this otherwise smooth looking area. This peculiar kind of stigma is constant in its occurrence in the varieties mentioned above and to our knowledge the first experience of its kind in the Gramineae. The setting of the seed is normal in spite of the restricted feathery area in the stigmas.

In recent years Entomologists all over India have been devoting a good deal of atterition to the study of the insect pests of sugar- cane. The authors have been making detailed, studies of the moth borers and their natural enemies. Of the several parasites collected the results of the studies of the three larval parasites, viz., Elasmus zehntueri, Ferr., Stenobracon nicevillei, Bingh and Phaconotus scirpophagae, Wiko., have already been published by the authors 1.2, 3. The present paper deals with Stenobracon deesae, Cam. The parasite belongs to the sub-tamily Vipioninae. it was described by Cameron 4 from specimens collected by C. G. Nurse in 1902 at Deesa, Simla and Ferozepur. Dr. Ramakrishna Ayyar 5. 6. states that it is one of the chief parasites of the stem boring Pyralid caterpillars of cane, sorghum and pulses. It is reported as an important parasite of Scirpophaga by Husain 7 from Punjab. Narayanan & mentions it as a parasite of the sugarcane root borer, Emmalo.era depressella, Swinh. It has also been recorded from Formosa, Java, Sumatra, China and the Philippines by Watanabe 9. The authors have collected this parasite from sugarcane and sorghum fields from Diatraea sticticraspis, Hmps., D. venosata, Walk. Chilo Zonellus Swink and Scirpophaga sp. The Coimbatore collections contain a single specimen of deesac labelled "from paddy".

A MUCH NEEDED LINK IN AGRICULTURAL DISSEMINATION WORK
Authors:   Tamil Nadu Agricultural University Coimbatore  641 003, N.C TIRUMALACHARY
Published: November 2023

In an agricultural country like ours the affluence of the nation is synonymous with the welfare of the cultivators who form the major component. Hence, any scheme for the advancement of this country must take them into consideration and outline ways and means to improve their knowledge and intellect, their customs and habits and their agricultural methods and machinery. It is well known that there is not much money in farming and even if the income is doubled the income may not be large. Still, agriculture, being the main industry of India, should form the foremost pro- blem to be tackled by a sincere economist who has the welfare of the country at heart. The remission of land revenue, the formation of debt conciliation boards, the establishment of land-mortgage banks, the enactment of the Debt relief and Tenancy bills and the introduction of the Prohibition Act are but a few attempts to relieve the distress among farmers. Concentration should be made more towards the enhance nent of their agricultural income. The proverbial conservatism of the ryot and his obstinate tendency to tread along his age-old path has to be broken and he must be persuaded to move with the times, study the present conditions of the markets and adopt the various Improved and economic methods of cropping advocated by the Agricultural Department. The establishment of Agricultural Colleges and Research Institutes, the patient and sincere toils of the Scientists and the results of all successful investigations are but only half the task, the other and perhaps the greatest task is to disseminate these results in villages. And no results of agricultural research, however important in themselves, can be considered of any value unless and until it is carried to the door of the individual cultivator.

Guntur with its good retentive black soil and an average rainfall of 35 inches a year is the most suitable tract for the cultivation of cigarette tobacco which should be grown only as a dry crop in order that the leaves may be of nuld flavour. For long, India produced and exported nothing but pipe tobacco and very low grade cigaretie tobacco. Up to 1920, only country tobacco leaf of narrow body, with a thick and stouf siem, with practically no colour, was produced and exported in leaf form to England, pressed into bales of 250 lbs. nett each. After 1920 owing to the imposition of heavy Import duty on tobacco in England, the London market wanted the tobacco to be in the form of strips Le, with the major portion of the thick mid-rib removed. The saving in terms of money can easily be appreciated when one considers the fact that the stems that are removed weigh as much as 25% of the whole leaf. Alter 1920, Virginia tobacco cultivation spread gradually in Guntur district and by 1924 large areas were grown. This Virginia variety contained less wood then the country, and the leaf was broad and silky. In the country variety the percentage of bright coloured leat was between. 1 to 2 of the total yield and the rest was a mixture of light brown, brown and dark leaves. In the Virginia tobacco the yield of bright coloured leat is found to range from 5 to 10%. The introduction of flue curing Improved the colour of the cured leaf and the percentage of bright coloured lesi increased from 5 to 10% in the case of sun cured, and to 40 to 50% in the case of flue cured tobacco. The foreign market appreciated the Improve ment in quality and good prices were paid for Guntur bright flue cured virginia strips, which gave a good impetus to the cultivators and the develop ment of flue curing was very rapid. In 1930 there were only about 200 barns in Guntur but by 1934 the number of barns in Guntur increased to 2500. On account of great demand for bright virginia flue cured tobacco in London market from 1936, the number of bams in Guntur tract increased rapidly to nearly 5000 in number during 1938 season. The manufacturing buyers in the United Kingdom commenced to blend larger quantities of this improved Indian Tobacco with the more costly American tobacco.

In last May I was deputed by the Government of Madras to study electro-cultural methods introduced by Dr. S. S. Nehru in Mainpuri, United Provinces, and by Col. Noel in Peshawar, North West. Provinces, and report on the results. It may be of interest to know that Dr. Nehru is a civilian officer work ing in the United Provinces, who had a brilliant educational career. After laking the B. A. and B. Sc. degrees at Allahabad at the early age of 16, he went to Cambridge, took two honours degrees and passed the T. C. S. examination. He then took his Ph. D. degree at Heidelberg University in Germany. He was for some time Professor of Physics, when he did some research work in aerodynamical problems. He presided over the Agricultural Section of the Indian Science Congress in 1934. He is a great enthusiast taking great interest at first in the introduction and spread of boorm corn and later on in electro farming. He has published a number of books and pamphlets on his new hobby.
POLLEN STUDY IN RELATION TO BEE PASTURAGE

Published: November 2023

The importance of a full knowledge of bee pasturage is well known to the practical bee-keeper. Almost complete treatises about bee flora exist in all the chief honey producing countries. So far as South India is concerned, the industry is still in its infancy. Except for the records of Ramachandran (1937) and Venkatasubbayya (1938), no detailed informa- tion appears to be available and the present study was undertaken to supple- ment the information provided by them. But the attempt to ascertain plant sources for honey and pollen has in almost all studies reported in India, mainly been confined to the location of flowers actually visited by bees. This method cannot be deemed satis- factory, for it may be that plant sources growing at a long distance away from the apiary are missed. Also the worker's personal prejudices as to the usefulness or otherwise of a particular source may sometimes vitiate the reliability or completeness of the list of plants arrived at. The study of the external morphology of pollen grains has always formed a subject of absorbing interest to botanists. Pope (1925) and Wode- house (1928 and 1935) have studied the morphological features of pollen grains which are characteristic of the several families, the genera and the species of plants. From their observations, it seems possible that such characters as the size and shape of the pollen grains, the number and arrangement of germ pores and furrows, the character of reticulations and of spines, and the texture of the surface can be utilized in ascertaining bee pasturage. The present author is not aware of any work in which the pollen characters have been utilized for ascertaining bee pasturage in India. From the observations made on the pollen carried by the bees, the plants that are visited by them have been located and the seasons and the hours during which such visits are made have also been determined.

A study was carried out to investigate the effect of fluoride on cholesterol synthesis in testicular tissue of rams. Sodium fluoride was added to the rations at two levels (50 and 100 ppm) on dry weight basis. At the end of the experiment, the animals were sacrificed and the right testes of each animal was removed and incubated with 1-C1- acetate in the presence and absence of HCG. Human chorionic gonadotropin stimulated cholesterol biosynthesis significantly in the control animals, but failed to do so in the fluoride treated rams. Fluoride, also, reduced cholesterol biosynthesis in the treated groups compared with the control animals. Itw was postulated that fluoride might alter cholesterol biosynthesis by influencing carbohydrate and lipid metabolic pathways.

Numerical study on the torsional behavior of CFRP-strengthened RC beams
Authors: Noha Yehia Elwakkad
Published: November 2023

The present paper offers a numerical study on the behavior of reinforced concrete (RC) beams strengthened with carbon fiber reinforced polymer (CFRP) under pure torsional loading. The failure mode of RC beams significantly changed in accordance with torsional loading. Therefore, the effect of strengthening RC beams by CFRP under torsion is a vital area of study. This paper attempted to fill the gap by conducting a numerical (Abaqus) study, whereby the numerical investigation was in line with the parametric for a previous study of an experimental program. The numerical model achieved agreement with the results of the experimental program, then, this model was used by applying CFRP, instead of GFRP. Additionally, the numerical study was completely in line with the parametric study in terms of sample dimensions, steel reinforcement, number of FRP layers, and width of FRP strips, for the aim of comparing results. The comparative evaluation in this study aims to contrast the behavior of RC beams strengthened by CFRP with the behavior of those strengthened by GFRP under pure torsion. Parameters such as ultimate torsional moment, and the maximum angle of twist were studied. The study revealed that strengthening with CFRP improved the ultimate strength and post-cracking stiffness, in addition to localizing the damage.
