DESIGNING A 34.5 kV DISTRIBUTION NETWORK WITH SUPERCONDUCTORS AND COMPARISON WITH THE EXISTING SYSTEM
Authors: GÖK Kevser , ÇAVUŞ Türker Fedai
Published: June 2023

Aim: Electrical energy goes through many different stages from its generation to delivery to the end user. In the transmission and distribution processes of the electrical energy, the energy losses may occur. It is essential to seek appropriate solutions to minimise the electrical power losses and to eliminate all parameters that impair the quality of energy so as to help the electrical network system can operate efficiently, economically, reliably and sustainably. In this study, a medium voltage distribution network and of all parameters were modelled and examined in the computer environment. Modelling and analysis processes were done through the DigSilent Power Factory program which can perform power system analyses. Method: The study consists of three stages. In the first stage, Rabak Feeder modelling of Izmit TM and some analyses of this feeder were made in the DigSilent program. In the second stage, all the underground aluminium conductors in Rabak Feeder were replaced with the superconductors and were modelled and analysed in the DigSilent Power Factory program. In the third stage, Rabak Feeder was redesigned with the superconductors and analyses were made. Results: As a result of these analyses, all parameters of the models were examined. The parameters obtained from the existing and the other two-stage models were compared. These comparisons show that the efficiency of the system increases while the voltage drops and energy losses both decrease when the superconductors are used. Conclusion: The use of the superconductors has increased the efficiency of the system by reducing the voltage drops and energy losses.

Published: June 2023

We presented a clinical case of idiopathic autoimmune brainstem encephalitis in a 12-year-old female patient. At the onset of the disease, which developed after a respiratory infection, the clinical picture was accompanied by oculomotor and bulbar syndromes. The diagnosis of Bickerstaff brainstem encephalitis was made based on clinical diagnostic criteria and the positive effect of the course of intravenous immunoglobulin therapy. During 3 years of follow-up, there were periods of relapse of the disease, during which symptoms not typical for Bickerstaff stem encephalitis appeared. Against the background of long-term immunosuppressive therapy, there was a long-term remission of about 2 years. The clinical picture, the presence of relapses, the data of additional methods forced to reconsider the diagnosis in favor of idiopathic autoimmune brainstem encephalitis.

Authors: Sukanya Vuppala , Ramachandram S.
Published: June 2023

Data collection from agricultural fields is tiring and requires novel methodologies to produce reliable outcomes. The combination of edge and wireless sensor networks (WSN) for smart farming enabled the efficient collection of data from remote fields to a vast extent. Adopting an optimization algorithm to achieve the data collection task is prioritized in the proposed work, and a new and effective data collection framework is proposed. The proposed framework initially collects the data from the agricultural fields via sensors and then transmits it to the edge server. The path between the sensors and the edge server is optimally obtained using the cat and mouse based task optimization (CMTO) model. The sensed data are transmitted through the optimal route, and then the edge server obtains and evaluates the data based on the data quality metrics such as precision, correctness, completeness and reliability. The valid data are then identified and transferred to the cloud servers for storage. The simulation of the work is done in Python platform and evaluated using the crop recommender dataset. The evaluations proved the method's efficacy compared to the existing state-of-the-art algorithms. The proposed work also provided upto 12.5% of improvement in terms of energy consumption, 7.14% of improvement in terms of communication latency, 4% of improvement in terms of execution cost, 2.27% of improvement in terms of completeness, 1.12% of improvement in terms of precision, 9.52% of improvement in terms of correctness, and 3.37% of improvement in terms of reliability.

Published: June 2023

The proposed development intends to establish an autonomous bank locker using industry-standard innovative locker technologies to deliver more flexible and reasonably priced semi-autonomous bank security mechanisms with minimal human intervention. In this design, there are two layers of locker security. The system proposed in this effort is a better security system regarding the number of security tiers. Its primary base is facial recognition. The first level is implemented by asking the user to input a passkey. A matrix keypad and Python programming are both employed. The user is then authorized to continue to the subsequent stage if a match is confirmed to exist. The second level was implemented using Python programming, OpenCV software, and face detection and identification techniques. To make Windows compatible with third-party apps Putty and Xming, the Raspberry Pi was linked to the laptop using IEEE 802.3 Ethernet and X11 forwarding on the UBUNTU operating system. IEEE 802.11 USB Wi-Fi was used to connect devices to the Wi-Fi network. The HAAR OpenCV standard has been used for face detection because of its better Face Acceptance and Rejection Ratio. The EIGENFACES OpenCV standard is employed for face recognition due to its efficacy, robustness, and simplicity.
TRANSLINGUALISM ACROSS LANGUAGES: A TEXTUAL ANALYSIS OF LANGUAGES INTERACTION
Authors: Sefotho Malephole , Charamba Erasmus , Quintero Genevieve
Published: June 2023

The myth of a pure form of language is so deep-rooted in many people that, even though they accept the existence of different languages, they cannot accept the reality that there is no language that is fully independent of other languages. People believe that there is language contamination across languages and most of the time it is their own language contaminated by others. This confirms the colonial principle of compartmentalization or distribution of languages. Even in the post-colonial era, language isolation remains a serious challenge, especially in bi/multilingual classroom settings, where learners are discouraged to translanguage or code-mesh languages. It is against this background that this paper examines adaptation of several vocabularies and concepts from other languages in developing a language, usually through merging of cultures or colonization. This study looks at examples in Southern Africa and the Philippines of existing fusion that has taken place between those languages and other surrounding languages. Therefore, this study argues that boundaries between languages are fluid - not fixed. The boundaries do not exist. They are therefore uncalled for because they destabilize the fluidity between languages, yet there is autonomous fusion between languages. We further argue that indigenization of languages can work well in translanguaged classrooms where learners are allowed to utilize indigenized versions of loan words to express ideas and concepts. This can encourage a more liberal use of language and self-expression in formal classroom settings.

Published: June 2023

Higher education institutions are the important chain in provision of the inter-connections between the workforce (school graduates, youth, or adults), representatives from different economic sectors, experts from research and innovation development organisations, and all the interested contributors. The research purpose is to build a new development model of sustainable communication for higher education institutions. This research is qualitative as it aims at constructing a new model. The research integrates the use of theoretical analysis, comparative analysis of existing models, theoretical modelling, model creation, summarising analysis. Very often the researchers think of the process of communication as a one-way process. The present work allowed for the establishment of the inter-connections between the development of the system of the external and internal perspectives, on the one hand, and the implementation of the process of sustainable communication, on the other hand. The novel contribution of this research is that the sender and the receiver of the information in the sustainable communication process act at the same time, their information meets and exchanges, thereby promoting information interaction or quasi-knowledge creation. Future research intends to include the empirical methods of research. Collection of quantitative data is a future research direction, too.
Analysis of Intrusion Detection Systems in UNSW-NB15 and NSL-KDD Datasets with Machine Learning Algorithms
Authors: TÜRK Fuat
Published: June 2023

Recently, the need for Network-based systems and smart devices has been increasing rapidly. The use of smart devices in almost every field, the provision of services by private and public institutions over network servers, cloud technologies and database systems are almost completely remotely controlled. Due to these increasing requirements for network systems, malicious software and users, unfortunately, are increasing their interest in these areas. Some organizations are exposed to almost hundreds or even thousands of network attacks daily. Therefore, it is not enough to solve the attacks with a virus program or a firewall. Detection and correct analysis of network attacks is vital for the operation of the entire system. With deep learning and machine learning, attack detection and classification can be done successfully. In this study, a comprehensive attack detection process was performed on UNSW-NB15 and NSL-KDD datasets with existing machine learning algorithms. In the UNSW-NB115 dataset, 98.6% and 98.3% accuracy were obtained for two-class and multi-class, respectively, and 97.8% and 93.4% accuracy in the NSL-KDD dataset. The results prove that machine learning algorithms are lateral to the solution in intrusion detection systems.

¿Es probable sufrir acoso en la academia? Percepciones de la comunidad universitaria
Authors: Villar Varela Milena , Barreiro Fernández Felicidad , Méndez-Lois María-José
Published: June 2023

El acoso en base al sistema sexo/género es un fenómeno presente en el ámbito universitario cuya existencia se puede advertir en las percepciones de la propia comunidad educativa, y que requiere ser estudiado en profundidad para así engendrar acciones realistas y prácticas para su prevención y erradicación. La aproximación al panorama actual de este tipo de acoso en una universidad española es el objetivo general del estudio. La muestra está conformada por 1066 miembros de la comunidad universitaria objeto de estudio, en concreto, 727 estudiantes, 125 profesionales del colectivo de administración y servicios y 214 docentes. Se realiza un estudio descriptivo, a través de sus percepciones sobre la probabilidad de sufrir acoso. El acoso sexual es el más observado en los tres colectivos y el acoso por identidad de género el menos percibido. La mitad de la muestra considera poco probable que se sufra acoso en la universidad y el grupo con menos probabilidad de sufrirlo son los hombres no LGBT+. Se concluye que las pedagogías feministas son el mejor recurso para combatir los distintos tipos de acoso estudiados en la academia, y en la sociedad en general.

Aim: to assess the state of periodontal tissues when planning and performing controlled orthodontic movement of crowns and roots of teeth using the overlay of computed tomography on 3-D visualization of the process of movement of dentition in patients with inflammatory periodontal diseases.
Methods: Based on the inclusion and non-inclusion criteria, the study involved 80 patients aged 25-35 years, who were divided into 2 groups - control (with clinically healthy periodontium) and main (with chronic generalized periodontitis) for orthodontic treatment of dentoalveolar anomalies. Orthodontic equipment for the comparison groups was identical (aligners, vestibular and lingual braces with passive self-ligation). Prior to the start of the orthodontic program, the alveolar morphotype was determined by CT of patients superimposed on the program for digital modeling of the future result; the optical density of the alveolar bone was estimated in Hounsfield units (HU). Clinical indicators for assessing the condition of periodontal tissues and after completion of the orthodontic program in the comparison groups.
Results: After the completion of orthodontic treatment, patients of group 1 had a lower number of periodontal complications - 42% versus 54% in group 2, with initially normal periodontium with a thin alveolar morphotype; 18% and 23% - with a thick alveolar morphotype. The best results were noted in the aligners subgroup - 16% and 18% for groups 1 and 2, respectively; the worst - in the subgroup with lingually fixed braces - 50% and 55%, respectively. The most common periodontal complication was tissue recession. Thanks to the predictive planning of the assessment of patients' computed tomograms superimposed on the program of digital modeling of the final result after the displacement of teeth, a positive result of orthodontic treatment was obtained and the risk of negative impact of the orthodontic program on both intact periodontal tissues and damaged periodontium was minimized.
Conclusions: The new ability to control the state of the alveolar ridge bone using 3-D visualization of tooth movement with CT overlay increases the efficiency of orthodontic treatment planning by 40%, ensuring a minimum of side effects and complications.

Published: June 2023

Background: Significant shifts in therapy paradigms for advanced laryngeal carcinoma have occurred more recently. The number of patients receiving surgery alone has significantly decreased, while the number of patients receiving radiotherapy and chemoradiotherapy has significantly increased. Both the treatment modalities have its own advantages and disadvantages. The present study is a consideration to compare the complication rate of both the treatment modalities in the treatment of laryngeal cancer.
Methods: The head and neck oncosurgery department at the Kolhapur cancer center in Maharashtra conducted a five-year retrospective record analysis of the patients treated for carcinoma larynx [2017-2022]. The current analysis included all patients with histopathologically confirmed laryngeal cancer.
Results: Of the 24 cases if upfront surgery, 8 cases had complications and 8 cases of post RT, 6 cases had complications and this difference was statistically significant (p<0.05). There was significant difference between the pharynocutaneous fistula rates among the two groups. The rates were higher among post radiotherapy patients (p<0.05).
Conclusions: The most common complication among post radiotherapy was pharynocutaneous fistula. The most common complications among upfront surgery were pharynocutaneous fistula and stomal stenosis. Pharynocutaneous fistula was significantly higher among post radiotherapy patients when compared to upfront surgery.

Published: June 2023

Background: Tinnitus manifests frequently with hearing loss. Isolated tinnitus in patients with self-professed normal hearing may have underlying auditory dysfunction.
Methods: We retrospectively reviewed the audiometry record of our department from January 2019 to October 2021. Pure tone audiometry thresholds of patients with isolated tinnitus were analyzed along with the demographics, degree and type of hearing loss.  
Results: Of 255 (132 males/123 females) patients, mean age 39.7±15.2 years (range: 10-80 years), tinnitus was maximum (49%) prevalent among 20-40 years group, 5.8% among the pediatric population and 8.6% amidst ≥60 years populace. Males predominated (52%) throughout except at 21-30 years age. 83% exhibited some degree of hearing loss (42% bilateral minimal loss, 11% bilateral mild hearing loss). 7% right ears (mostly >50 years age group) and 11% left ears showed greater than mild hearing loss. Bilateral tinnitus presented more (52%) followed by left tinnitus (29%) than right (19%). Mild hearing loss predominated right tinnitus presentation while minimal loss was recorded in left and bilateral tinnitus. However, greater than mild degree of hearing loss was clustered among bilateral tinnitus (14%) followed by left tinnitus (11%) than right tinnitus (6%). 18% had sensorineural deafness and all these patients had bilateral tinnitus. 30% had high frequency hearing loss and 39% among these had 4 kHz dip.
Conclusions: Isolated tinnitus may be a premonitory symptom of an underlying or an evolving auditory dysfunction. Bilateral tinnitus followed by left tinnitus presentation warrant higher index of suspicion.

Published: June 2023

Background: Metabolic syndrome (MetS), insulin resistance (IR) and papulosquamous diseases with shared pathophysiology leads to conglomeration of risk factors of non-communicable diseases like cardiovascular disease (CVD) and type 2 diabetes (T2D) causing high mortality worldwide. The objective is to study the association of MetS and IR in papulosquamous diseases.
Methods: It is a hospital-based case-control study conducted on 200 age-sex matched cases and controls with consent. Subjects were administered a pre-validated questionnaire, diagnosis of papulosquamous diseases was based on clinical examination and skin biopsy. MetS was diagnosed based on national cholesterol education program's- adult treatment plan iii with Asian modification for abdominal circumference criteria. Fasting serum insulin levels (FI) was used as a surrogate marker of IR. 
Results: Mean serum HDL- C level was low and statistically significant (p=0.017). Mean fasting plasma glucose level was significantly higher in patients (p=0.008). Mean FI level was significant between cases and controls (p=0.013). IR was found in 76% of cases which was significantly higher than in controls (p<0.05). IR was highest in psoriasis 29% followed by LP 22%, PRP 19%, and LS 6% which was statistically significant (p<0.05). MetS was mostly found in psoriasis (17%), LP (9%) and least in PRP, LS.
Conclusions: This study intends clinicians to do periodic MetS and IR evaluation in papulosquamous diseases. Thus, subclinical cases of non-communicable diseases can be detected and potential co-morbidities can be prevented.

This study aims to investigate the confidence level of undergraduate final-year dental students in performing root canal treatment (RCT) and the relationship to the problems encountered during RCT.

A validated online questionnaire was distributed to final-year dental students at Universiti Teknologi MARA. The questionnaire utilized both scaled responses and closed-ended questions to gain data regarding students’ confidence levels in performing root canal treatment.

: In this study, 93.4% of the students were confident in placing a rubber dam, 90.8% were confident in injecting local anesthesia and root canal irrigation. Procedures that were rated as least confident were access cavities and management of interappointment flare-ups. For the mean rate of self-confidence in performing RCT in the dentition, maxillary anterior teeth (4.24±0.63) ranked highest followed by mandibular premolars (4.11±0.72), whereas the least confidence was in treating maxillary molars (3.38±0.69). Higher scores of self-confidence were in the management of necrotic pulp (4.22±0.65), followed by vital pulp treatments (3.95±0.61). The main mishaps that students encountered were canal blockage (57.9%) and underestimation of length (52.6%). There is no statistically significant correlation between the confidence level and encountered errors. .

: The mean overall confidence score of different endodontic procedures was high, which is 80%. Examining the confidence level of students is a crucial part of this study, which can help to enhance the quality of endodontic education in areas that need improvement.

Published: June 2023

A benign bone neoplasm known as an osseous fibroma is frequently referred as fibro-osseous lesion. It has a stronger preference for females and is thought to have originated from periodontal membrane. Maxilla is less often afflicted than the mandible. This bone neoplasm is made up of highly cellular, fibrous tissue with varied levels of calcified tissue, which may resemble cementum, bone, or both. Depending on the degree of calcification, the lesions are either entirely radiolucent, mixed, or fully radiopaque with a radiolucent margin. Due to its propensity for recurrence and potential for malignant change, ossifying fibromas necessitate extensive surgery. In this case, a 20-year-old female had a large ossifying fibroma of mandible.

Published: June 2023

A stable and specific heat shock protein 27.2 (HSP27.2) antibody was prepared and analyzed for protein level research in Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae). The full-length hsp27.2 was amplified from H. armigera larvae and constructed into the prokaryotic expression vector. The purified His-tag fused protein was used to immunize rabbits for the antibody preparation. Western blot analysis indicated that this antibody specifically recognized the HSP27.2 encoded by H. armigera and detected the HSP27.2 encoded by other noctuid larvae. Further analysis of HSP27.2 expression in H. armigera under infection by different pathogenic microorganisms and in different tissues showed that the expression of HSP27.2 is continually stable. The HSP27.2 antibody is efficient and capable as a reference antibody for functional studies involving genes and proteins in H. armigera and other lepidopteran insects.

Published: June 2023

BACKGROUND: 25(OH)D level is correlated with insulin secretion and tissue sensitivity to insulin. Administration of vitamin D supplements may reduce tissue resistance to insulin in type 2 diabetes mellitus (T2DM), but a number of studies found conflicting results. The present study was to measure the results of administration of vitamin D supplements for 3 and 6 months regarding HbA1c, fasting blood glucose (FBG), insulin and tissue resistance to insulin in T2DM cases.METHODS: A randomized double-blind placebo-controlled trial was conducted in T2DM patients with ≤3 years duration. Subjects were randomly divided into two groups: 47 subjects received daily 5000 IU vitamin D supplementation and 47 subjects received daily placebo as control. After supplementation for 3 and 6 months, homeostatic model assessment for tissue resistance to insulin (HOMA-IR), insulin, HbA1c, and FBG were examined.RESULTS: Supplementation of daily 5000 IU vitamin D for 3 months increased 25(OH)D level in the vitamin D group from 12.50±5.28 to 43.57±17.14 ng/mL, and after 6 months the 25(OH)D level was 38.38±17.64 ng/mL. Both groups showed significant differences after 3 and 6 months regarding HOMA-IR (p=0.033 and p=0.031), insulin (p=0.034 and p=0.013), but not FBG (p=0.296) and HbA1c (p=0.360). In both groups, HOMA-IR and insulin increased although the increase in the control group was greater than in the vitamin D group. The difference between the control and vitamin D groups was significant.CONCLUSION: Vitamin D supplementation for 3 and 6 months may lead to improvement HOMA-IR but not for FBG and HbA1c in the vitamin D group as compared with the control group in T2DM cases.KEYWORDS: vitamin D, T2DM, HbA1c, blood glucose, insulin, tissue resistance to insulin

Published: June 2023

La sostenibilidad se considera como elemento indispensable para mejorar la calidad del sector turístico, por lo tanto, la preservación del medioambiente ha recibido una considerable atención crítica desde una perspectiva turística. En este marco, la investigación ha comenzado a prestar atención a la educación en turismo sostenible, sin embargo, escasos estudios han analizado los conocimientos de los estudiantes con respecto a la sostenibilidad. Por consiguiente, este trabajo tiene como finalidad el análisis del conocimiento y de las actitudes de los estudiantes hacia el turismo sostenible. La atención se centró en Bogotá, donde la actividad turística ha causado graves impactos negativos y donde el conocimiento y las habilidades de la sostenibilidad son más necesarios para proteger los frágiles recursos naturales y culturales. Los resultados muestran que, aunque la mayoría de los estudiantes de turismo piensan que el turismo sostenible es importante, tienen un conocimiento limitado de los principios de sostenibilidad y los aspectos técnicos relacionados con el turismo sostenible.
COVID-19 e informalidad en prestadores de servicio turístico en los departamentos de Cundinamarca y Antioquia, Colombia
Authors: Zurbarán Arias Deiwi Jesús , Quintero Arango Luis Fernando , Piñeros Sairi T.
Published: June 2023

La aparición del COVID-19 profundizó problemas estructurales tales como la informalidad en países en vías de desarrollo; para el sector turístico, este ha sido un factor determinante sobre su productividad y competitividad de cara a prácticas sostenibles. Se buscó establecer la relación entre el COVID-19 y la informalidad en prestadores de servicio turístico ubicados en los departamentos de Cundinamarca y Antioquia (Colombia). Se estableció una muestra de tipo no probabilística de 209 prestadores y se aplicó una encuesta para analizar variables como Registro Mercantil, Registro Nacional de Turismo (RNT), salarios, vínculo laboral y afiliación al Sistema General de Salud y Seguridad Social (SGSSS). Se recolectaron datos cualitativos ordinales, codificados y tratados mediante metodologías de análisis de correlación y asociatividad (Coeficiente τ de Kendall). Se evidenció que hay un bajo nivel de asociatividad entre las variables estudiadas: en restaurantes y bares prevalece un mayor nivel de informalidad, en cambio, en alojamientos y restaurantes predomina la vinculación laboral por medio de acuerdos verbales que no garantizan a los trabajadores condiciones de calidad y trabajo digno.
Lugares parientes : Comida, cohabitación y mundos andinos
Authors: Salas Carreño Guillermo
Published: June 2023

A partir de investigaciones que muestran cómo la provisión de comida y la cohabitación son fundamentales en la construcción del parentesco en los Andes, Guillermo Salas Carreño, el autor de este texto, nos revela cómo esta misma lógica está presente en otras interacciones sociales: desde aquellas entre una persona y sus afines, vecinos, paisanos, extraños, muertos, hasta aquellas con montañas, lagunas, campos de cultivo, avenidas o plazas; esto es, con lugares que pueden ser también parientes. El autor recurre al término ruwales para referirse a estos lugares con nombre propio a los que se les atribuye agencia e intencionalidad y, a través de comparaciones históricas, muestra las diferentes maneras en que estos seres se relacionaban con los hacendados y las instituciones estatales antes y después de la reforma agraria, con la minería de socavón previa al boom minero y con la actual minería de tajo abierto. El libro combina un enfoque procesual de análisis del parentesco, que no asume la reproducción sexual como el fundamento universal del mismo, con trabajos recientes alrededor de socialidades que exceden a los seres humanos, la multiplicidad ontológica y la cosmopolítica indígena en la antropología contemporánea.
Historia de las literaturas en el Perú Volumen 5. La narrativa peruana contemporánea. Cuento y novela (1920-2000)
Authors: Marcone Jorge , Portugal José Alberto
Published: June 2023

Los ensayos reunidos en este volumen se concentran en la producción de narrativa de ficción, novela y cuento, y ofrecen una cobertura amplia de esta producción desde el año 1920 al año 2000. Los ensayos han sido distribuidos en tres secciones. El material de la primera ofrece lo que normalmente entendemos como una forma reconocible de presentar el origen y desarrollo de la narrativa contemporánea en el Perú. Se trata, en gran medida, de asuntos, géneros, obras y autores a partir de los cuales se ha definido el canon de esta narrativa a lo largo de las décadas de 1920 y 1970. La segunda sección propone visiones alternativas: presenta cuatro estudios que retan la integridad de una narrativa pensada dentro de las coordenadas del cauce central. Evidencian la insuficiencia de esa perspectiva al hacer visible una vasta producción que plantea cuestiones y problemas fundamentales, tanto en lo referente a los ámbitos de la representación como a las formas de la experiencia y la imaginación sociales activas a lo largo del siglo XX. Se concentran estos ensayos en aspectos específicos atendiendo a criterios de género o etnia, o enfatizando modos narrativos opacados y redefiniendo el ámbito de representación más allá de la dicotomía costa-sierra. La tercera sección está dedicada a una coyuntura particular, las dos décadas que cierran el siglo XX: las raíces del presente. Aquí podemos observar la compleja articulación de distintas épocas y sensibilidades: vemos la multiplicación de canales y la presencia en escena de una multitud de autores y de agendas narrativas e ideológicas, así como también diferentes entonaciones en el diálogo con la tradición literaria. El propósito de esta estructuración es sugerir posibles lecturas del corpus, y dar cuenta de distintas interpretaciones del origen y desarrollo de la narrativa contemporánea en el Perú.

Published: June 2023

Los Guayacundos Ayahuacas: una arqueología desconocida, “acertado título para una obra que rescata y revalora la identidad de una de las más importantes etnías de la Sierra Norte del Perú. Si bien fueron mencionadas por las fuentes históricas de los siglos XVI y XVII, permanecían aún desconocidas en su profunda raigambre prehistórica que debe remontarse a los albores de la civilización andina, como parecen probarlo las invalorables y novedosas evidencias que nos presenta Mario Polia a través de este espléndido compendio, reflejo de más de dos décadas de reconocimientos, prospecciones y excavaciones en las desconocidas tierras de los Andes piuranos”

Agua y poder en la sierra peruana : la historia y política cultural del riego, rito y desarrollo
Authors: Gelles Paul H.
Published: June 2023

En los Andes peruanos, al igual que en muchos otros lugares del mundo, el agua de riego es un elemento clave para la producción agrícola y una fuente de importantes significados y conflictos. Considero que para entender un sistema de riego, primero es necesario entender a la comunidad. Como forma social predominante y productora de cultura en Ecuador, Bolivia y Perú, la comunidad andina debe entenderse como una entidad atravesada por conflictos inherentes a ella. Encarna, a la vez, una orientación cultural en donde la identidad local y la producción se vinculan estrechamente con los paisajes sagrados. En este análisis recalco que los sistemas de riego en la zona andina también deben enfocarse considerando las fuerzas regionales, nacionales e internacionales que penetran en la comunidad. Asimismo, es necesario tener en cuenta la profunda brecha cultural presente en la sociedad peruana contemporánea. Mediante el estudio de las raíces históricas, la lógica cultural y las fuerzas políticas de los modelos de riego estatales y locales en la comunidad andina de Cabanaconde, demuestro que diversos campos de conflicto -entre miembros de una comunidad diferenciada por un lado, y entre el Estado y la comunidad por otro- están Íntimamente vinculados.

Una concepción trágica de la cultura
Authors: Baptista Selma
Published: June 2023

Parafraseando a Unamuno, Selma Baptista propone un recorrido por el desarrollo de la antropología en el Perú a través de los diversos discursos sobre la identidad y lo nacional establecidos por diversos intelectuales, artistas, escritores, y obviamente antropólogos; y también sobre cómo esta disciplina se ha ido relacionando desde mediados del siglo veinte con sus objetos de estudio. Los capítulos más saltantes del libro están dedicados a Mariátegui y su azarosa travesía intelectual a lo largo de sus cortos 36 años de vida, y a Arguedas, el escritor y antropólogo que hizo de su vida entre dos orillas un proyecto intelectual, que lo llevó al desgarramiento y al suicidio. Estas vidas -junto a sucesos como los de Cajamarca de 1532- configuraron un discurso trágico de lo peruano y una concepción de cultura inacabada, en permanente ebullición o en estado de formación. Lectura interesante, más allá de cierto lenguaje especializado y, por momentos, denso.
Ignatzschineria cameli Strain KAUPDF7-A First Report on Plant Growth Promoting Rhizobacteria (PGPR) from the Post-flood Affected Soils of Kerala
Authors: Haseena A. , Gopal K. Surendra
Published: June 2023

Background: Kerala flood in 2018 and 2019 had reduced the yield in many agricultural plots of Attapadi, Kerala, India. The scope of the study was to identify the potential native plant growth promoting rhizobacteria from the post flood-affected sites to rejuvenate the nutrient depleted soils. Methods: The present study was carried out in the department of agricultural microbiology, College of Agriculture, Kerala Agricultural University, Vellanikara, Kerala during 2020-2022. Bacteria were isolated from post flood-affected agricultural soils of Attapadi in Palakkad district of Kerala, India. Three morphologically distinct isolates were screened for cellulase, laccase and dehydrogenase to select the best bacterial isolate that could produce the multifunctional enzymes for rejuvenation of flood-affected soils. The isolate were also screened for plant growth promotion traits such as; indole acetic acid (IAA), phosphate solubilizing ability, nitrogen fixing ability and potassium solubilizing ability. Result: The most promising isolate was identified as Ignatzschineria cameli, which was found to be a high indole acetic acid producer along with phosphate and potassium solubilizing ability and revealed as the first report of PGPR from post flood-affected soils of Kerala.
Foundations of the Positive Affect Tolerance Protocol: The Central Role of Interpersonal Positive Affect in Attachment and Self-Regulation
Authors: Leeds Andrew M.
Published: June 2023

Research has highlighted the negative effects of early neglect and abuse on the development of emotional self-regulation and attachment. Attention has focused more on negative affect states related to past adverse and traumatic experiences than on the deactivating effects of the absence of early shared positive affect states from parent-infant play, warmth, and affection. Treatment strategies for survivors of early neglect and abuse have focused on methods to metabolize memories of traumatic events. Skills development models have emphasized the benefits of distress tolerance, acceptance, and mindfulness training for patients with persistent negative affect states. Research on the benefits of therapeutic interventions intended to increase positive affect indicates they promote prosocial behaviors and creativity, broaden the scope of attention, reduce emotional symptoms and behavioral problems, and improve physical health. Within the field of eye movement desensitization and reprocessing (EMDR) therapy, procedures to increase positive affect have generally focused on resource development and installation procedures intended to increase access to positive affect-related memories and images. A neglected clinical issue is the inability of survivors of early neglect to tolerate and integrate actual positive interpersonal experience into positive emotional states, interpersonal scripts, or self-concepts. These deficiencies, characteristic of those with dismissing insecure attachment, help produce and maintain profound psychological, medical, and social problems that limit the ability of patients with these histories from progressing in psychotherapy. This article explores research supporting the potential benefits of an EMDR-related procedure, the positive affect tolerance (PAT) and integration protocol, along with possible mechanisms by which the PAT protocol in general, and its bilateral stimulation procedures, might produce clinical benefits for survivors of early neglect. Case vignettes illustrate the potential challenges of implementing and the potential impact of the PAT protocol. Research designs and assessment tools are described that could clarify the potential benefits of the PAT protocol compared to other treatments designed to increase positive affect.
On the Operation of a Combined Culvert in the Body of a Double-Track Embankment
Authors: Perminov Nikolay
Published: June 2023

Purpose: To find out features of operation of precast reinforced concrete culverts in the embedding soil bulk of the two-track embankment with account of interaction of precast culvert structures and soil for the case of oppositely directed towards the first and second tracks combination of horizontal components of train loads at opposite transit of trains in the ulvert area; to propose on selection of methods of reinforcement of culvert structures with account of conditions of their operation in the two-track subgrade. Methods: The analysis and use of analytical and expemental research methods for evaluating operation of culverts in the body of the subgrade including two-track setions of railway. Analytical comparison of research results and data of instrumental observations. Results: There have beendentified the features of interaction of the body of the precast culvert with the body of the two-track embankment at oppositely directed horizontal components of the train load, there has been analyzed the nature of distribution of stress-strain state of the embedding soil bulk of the two-track subgrade along the culvert body. There has been demostrated a negative influence of the combination of oppositely directed towards the first and second tracks combination of horizontal components of train loads at opposite transit of trains on the body of the precast culvert in the embankment of two-track sections. Practical significance: The obtained results concerning the stress-strain behavior of the embedding soil bulk and distribution of forces along the culvert body at combination of oppositely directed horizontal actions at the two-track subgrade allowed identifying the nature of their joint operation and, based on it, proposing on selection of methods of reinforcement of culvert structures with account of conditions of their operation in the subgrade of two-track parts of railways.
