Authors: YÜKSEL Tahsin , İZGİ Abdulkadir
Published: May 2023

Sıvı soğutucu akışkanı içerisine nano boyuttaki metal partiküller karıştırılarak motor içerisindeki ısı iletimini arttırmak mümkündür. Bu çalışmada da bir taşıtın motor soğutma sistemindeki baz soğutucu akışkan içerisine %0,1 ve %0,2 oranlarında SiO2, TiO2, Al2O3 nanoakışkanları ilave edilerek 1000, 2000, 3000 ve 4000 dev/dk çalıştırılan motorun soğutma sistemindeki sıcaklık değişimleri incelenmiştir. Ayrıca bu devirlerdeki CO2, HC, CO, NOx ve O2 egzoz emisyonlarındaki değişimler de incelenmiştir. Baz akışkana eklenen nanoakışkanların oranları arttıkça ısı iletiminin arttığı, ancak 3000 ve 4000 dev/dk ısı iletimin düştüğü gözlemlenmiştir. Düşük sıcaklık değerleri için çalışılan tüm nanoakışkan karışımlarında görülen olumlu ısı iletim etkisi, motordaki devir artışıyla birlikte soğutucu sıcaklık değerlerinin yükselmesi durumunda görülmemiştir. Dolayısı ile nanoakışkan karışımlarının her koşulda ısı iletimini iyileştirmediği belirlenmiştir. Ayrıca partikül oranındaki artış ısı iletiminde olumlu etkiye sahip olduğunu göstermiştir. CO2, HC, CO ve O2 emisyonları için baz akışkana kıyasla egzoz emisyon değerlerinde belirgin farklılıklar oluşmamıştır. NOx emisyon değerlerinde ise farklı motor devirleri için sırası ile yaklaşık %28, %27, %25 ve %21 oranında düşüşler olduğu tespit edilmiştir. Sıcaklık ve emisyon ölçümlerinde genelde en iyi sonuçlar %0,2 SiO2 nanoakışkanında elde edilmiştir.

Published: May 2023

Yüksek bant genişliğine duyulan ihtiyaç sebebiyle dağınık fiber Raman yükselteçlerine (FRY) olan ilgi artmaktadır. FRY’ler geniş bant aralığını kullanmasının yanında düşük gürültü faktörü avantajı ve kullanımdaki basitlik ile de ön plana çıkmaktadır. Bu çalışmada SMF-28 türü fiberlerde kazancı düzleştirilmeye çalışılan 50 km mesafeye sahip bir fiber hatta ilerleyen 100 adet optik sinyale zıt yönde sırasıyla 4, 8, 16 adet pompa sinyali göndererek dağınık fiber raman yükselteç sistemi kurulmuştur. Kurulan sistemde sinyal kazancını düzleştirmek için lineer olmayan FRY modeli, optimizasyon problemi olarak tanımlanarak ikili arama denklemli adaptif yapay arı kolonisi algoritması (İADAYAK) ile çözülmüştür. Sonuçlar incelendiğinde 4 adet pompa kullanılarak elde edilen ortalama net kazanç farkı 0,16 dB, net kazanç farkı ise 0 ± 0,4 dB olarak bulunmuştur. 8 adet pompa kullanılarak elde edilen ortalama net kazanç farkı 0,043 dB, net kazanç farkı ise 0 ± 0,1 dB olarak ortaya çıkmıştır. 16 adet pompa kullanılarak elde edilen ortalama net kazanç farkı 0,028 dB, net kazanç farkı ise 0 ± 0,05 dB olarak tespit edilmiştir. Yapay zekâ teknolojisi kapsamında üretilen algoritmaların gelişmesi paralelinde bu çalışmaya benzer çözüm performanslarının gelişeceği ve bu sayede elde edilen verimin artacağı düşünülmektedir.
Derin kuyu pompalarında kritik dalma derinliğinin boyutsuz büyüklükler ile ilişkisi
Authors: ORHAN Nuri
Published: May 2023

Bu çalışmada, derin kuyu pompalarının kritik dalma derinliğinin belirlenmesinde boyutsuz büyüklükler ile ilişkilendirilmesi yapılmıştır. Genellikle kritik dalma derinliği belirli bir çapa sahip su girişlerinde ve santrifüj pompalarda yapılmıştır. Farklı anma çapına sahip iki adet milli pompa için üç farklı su giriş ağzı modelleri oluşturulması, kesit alanına sahip su giriş ağızları çap ile ilişkilendirilmesi ve kritik dalma derinliğinin boyutsuz büyüklükler ile ilişkilendirilmesi bu çalışmanın özgünlüğünü oluşturdu.

Pompaların kritik dalma derinliği vakum ölçüm yöntemine göre belirlendi. Her bir modelin değişik debi değerlerindeki kritik dalma derinliği seviyesi, diğer araştırmacıların Froude sayısına bağlı dalma derinliği eşitlikleri ile karşılaştırıldı. Pompaların kritik dalma derinliklerinin belirlenmesinde bu çalışmada geliştirilen eşitliğin kullanılması pompaların güvenilir (vorteksiz) bölgede çalışmasını sağlayacaktır. Vortekslerin oluşum derinliğine ve tipine fiziksel modellerin etkili olduğu ortaya çıktı. P1 pompasının fiziksel modelleri için Fcr (kritik froude sayısı) ≤1,40, P2 pompası için ise Fcr≤1,44 olması gerektiği bulundu. Bu değerler pompaların kuyuya yerleştirme yüksekliğinin belirlenmesinde kullanılabilir. Pompaların su giriş alanlarının artması kritik Weber sayısı ile Reynolds sayısını düşürdü. Her iki pompa içinde vorteks oluşum derinliği bakımından orjinal fiziksel modellerinin (D2) kullanılması uygun olacaktır. Sonuç olarak boyutsuz büyüklükler derin kuyu pompalarının kritik dalma derinliklerinin belirlenmesinde kullanılabilir.
The effects of carisoprodol on endochondral ossification: A review of the literature and implications for bone health
Authors: YRKM Sai
Published: May 2023

Carisoprodol is a medication commonly prescribed for musculoskeletal pain, but recent studies have raised concerns about its potential negative effects on bone development and health, particularly in relation to endochondral ossification. Endochondral ossification is a critical process that involves the transformation of cartilage into bone, which is essential for the formation of long bones in the body. Carisoprodol has been shown to reduce the activity of osteoblasts while increasing the activity of osteoclasts, leading to an imbalance in bone formation and resorption. Studies also suggest that carisoprodol may inhibit osteoblast differentiation, decrease bone density, strength, and microarchitecture, and affect the expression of genes involved in endochondral ossification. These negative effects may be due, in part, to its inhibition of the Wnt signaling pathway. Healthcare providers should carefully consider the potential risks of carisoprodol on bone development and health when prescribing this medication. Alternative treatments may be considered for patients at high risk of bone-related complications.

Background: Generally, in the aging process, there is degradation of autonomic nervous control mechanisms, compromising the regulation of heart rate, which contributes to increased frailty and the risk of falls. This process is defined as a geriatric syndrome that leads to impairment of physiological systems and homeostatic imbalance. Objective: To correlate heart rate variability (HRV), frailty parameters, and the risk of falls in elderly people from a community center. Methods: This research will involve active seniors and participants from the Centro de Convivências de Praia Grande, São Paulo, Brazil. Clinical, demographic, and anthropometric data, psychological variables, and physical conditions will be collected through the International Physical Activity Questionnaire (IPAQ) and the risk of falls test. The heart rate R-R intervals will be analyzed using the H10 polar frequency meter and the HRV application, and transferred to the Kúbios software for further analysis.Results: Two hundred and fourteen participants are involved in this study, 181 (84.6%) of whom are female, 137 (64.0%) are white, with a mean age of 70.27 ± 7.07 years, a weight of 68.37 ± 11.15 kg, and a body mass index of 27.04 ± 4.04 kg/m2. Conclusion: A positive correlation is expected through the stratified analysis of frailty indices, risk of falls, and HRV, suggesting that the lower the HRV, the greater the risk of falls and the greater frailty in the elderly.

Published: May 2023

BACKGROUND: The problem of medical rehabilitation/habilitation of patients with diseases of the nervous system, mental disorders, congenital anomalies and developmental delays is extremely relevant. The article analyzes the comprehensive care for this category of patients on the basis of the State Budgetary Institution Center for Comprehensive Rehabilitation of the Disabled "Butovo".
AIM: analysis of the volume and methodology of prescribing physical factors in the provision of medical and social services to patients at the State Budgetary Institution Center for Comprehensive Rehabilitation of the Disabled "Butovo".
MATERIALS AND METHODS: In 2021, based on archival data for 20192020 an assessment was made of the conduct of socio-medical rehabilitation at the State Budgetary Institution Center for Comprehensive Rehabilitation of the Disabled "Butovo". The observation unit is represented by stationary patient charts.
RESULTS: The study revealed a sufficient volume and correct methodology for prescribing physical factors to patients with diseases of the nervous system, mental disorders, congenital anomalies and developmental delays. At the same time, the absence of an adequate goal of rehabilitation/habilitation was noted. The goals that were set for patients were often unrealizable, non-specific, not defined in time, or not related to the needs of the patient himself.
CONCLUSION: A unified comprehensive approach is needed to assess the condition, identify needs and implement rehabilitation measures for patients with diseases of the nervous system, mental disorders, congenital anomalies and developmental delays. It has been determined that in this category of patients it is advisable to apply the International Classification of Functioning, which will allow one to concentrate on the necessary areas of diagnostics, select the necessary diagnostic tools, identify and link functional disorders and disability to each other, determine the areas of intervention of different specialists, unite specialists into one team with overall goal of rehabilitation/habilitation.

Assessing Fiscal Sustainability in Indonesia
Authors: Widiastuti Nur , Fitrady Ardyanto , Widodo Tri
Published: May 2023

Fiscal sustainability is a concern in many economies, especially with increasing government debt in many countries, including Indonesia. This study aims to analyze fiscal sustainability in Indonesia for the 1970-2018 period. There are two methods to measure fiscal sustainability: testing the stationarity of government debt using government budget constraints and estimating fiscal sustainability using the fiscal reaction function. Error Correction Model is used to estimate the fiscal reaction function. The fiscal sustainability test with the debt stationarity test and the fiscal reaction function had consistent results, indicating fiscal sustainability in Indonesia. The government responded well to the increase in debt by increasing the primary surplus. This study proves that the relationship between debt and primary balance is not linear or quadratic. It shows that initially, the government responds to an increase in debt by increasing its primary surplus. However, at a certain threshold, the government’s ability to respond will weaken, so the government needs to pay attention and maintain the size of the government debt ratio towards Gross Domestic Product with fiscal discipline and fiscal reform through strict regulations and prudent debt management. However, strict debt regulations can limit economic growth. Therefore, an accurate threshold calculation is needed to determine the maximum debt to encourage optimal economic growth.
Security Risk Analysis of the Internet of Things
Authors: Mandapuram Mounika
Published: May 2023

The Internet of Things is assisting in developing a new and more intelligent world in which everything will fall under its purview. The issue of security is by far the most critical concern and component regarding the Internet of Things. With billions or trillions of connected devices, it will be difficult for future generations to find solutions to the security concerns we face today. The Internet of Things (IoT) paves the way for various entities and applications that benefit humanity. Although it is the most significant accomplishment of the decade, it has also given rise to catastrophic scenarios due to security concerns such as threats, vulnerabilities, and attacks on connected and interconnected devices and objects. Despite this, it is still the most significant achievement of the decade. Businesses and organizations are backing the current paradigm shift by providing financial assistance to researchers and academics. The industry expected to have the most growth over this decade is the Internet of Things, which will connect trillions of different devices. It is anticipated that IoT will alter the method by which we communicate. The Internet of Things poses many significant dangers, including physical attacks, network attacks, encryption attacks, software attacks, authorization, surveillance, identity theft, vandalism, and secure communication. The findings of this research show that none of the IoT security architectures include a security layer.

Association of Chlamydia trachomatis and Neisseria gonorrhoeae with female infertility: a systematic review and meta-analysis
Authors: Majnooni Araz , Jamedar Saeed Amel , Azimian Amir , Ghazvini Kiarash
Published: May 2023

BackgroundChlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) are commonly diagnosed sexually transmitted infections that have been associated with serious reproductive health outcomes for women. The association of CT and NG infection with female fertility is not completely established yet. This review aimed to determine the association of CT and NG with female infertility.
MethodsThis systematic review and meta-analysis was conducted according to the PRISMA statement. We searched a range of electronic databases, including PubMed, Web of Science, Embase, and Scopus, from Sept 25, 2017 until February 1, 2021. From the 851 studies screened, 552 that failed to meet our eligibility criteria were excluded. Subsequently, we removed 290 studies for not having a possible correlation of CT and NG infections with female infertility. Nine studies comprising 1827 infertile patients met our inclusion criteria. Two investigators independently extracted a range of data. All analyses were performed using STATA (version 13.1, Stata Corp, College Station, TX, USA).
ResultsCT infection potentiates female infertility, as 76.47% of the included studies found a positive correlation between them. However, due to the limited number of reported data, we were not able to compare NG infection prevalence in fertile and non-fertile patients. Overall prevalences of CT and NG infections among infertile patients were 12 % and 3%, respectively, while CT infection prevalence among the fertile group was 7%.
Conclusion The prevalences of CT and NG infections were high in infertile women. Screening and treatment of C. trachomatis and gonococcal infections during infertility treatment might increase the pregnancy rate.

Authors: Aryana I Gusti Putu Suka , Paramita Ida Ayu Pradnya
Published: May 2023

BackgroundThe severity of COVID-19 infection has an increasing trend in the elderly, which contributes to the high morbidity and mortality rates in this population. Aging itself is a prominent risk factor for severe disease and death from COVID-19.
Case DescriptionThis case report a 71-year-old woman who complained of shortness of breath for 3 days before being admitted to the hospital. Bilateral consolidation and increased bronchovascular pattern were found on chest radiograph, and a positive SARS-COV2 nasopharyngeal swab PCR test result was noted. This patient was diagnosed with confirmed severe manifestation of COVID-19, community-acquired pneumonia and type 1 respiratory failure, as well as type II diabetes mellitus and suspicion of acute gastritis. The results of the geriatric status assessment were moderate functional status, risk of malnutrition, and moderate risk of deep vein thrombosis (DVT). This patient underwent treatment in accordance with the COVID-19 protocol along with management for geriatric status improvement. The patient was given permission to return home after 14 days of treatment, during which time her health had improved and her functional status had changed to moderate dependency. During follow-up, the patient continued to receive therapy. She is still being observed and future evaluations will be conducted.
ConclusionThe increased susceptibility of the elderly to COVID-19 infection is caused by various factors. A burden of death and long-term disability brought on by this pandemic may be lessened by new or modified therapies that target aging-associated mechanisms. Therefore, COVID-19 case management in this population should be done with a comprehensive approach.
Resistance genes of Neisseria gonorrhoeae to cefixime and azithromycin
Authors: Utami Louisa Ivana , Rosana Yeva
Published: May 2023

Gonorrhea is the second most common sexually transmitted bacterial infection (STI), following Chlamydia. Neisseria gonorrhoeae resistant to antibiotics are increasing globally in the world. In recent years, many studies have reported reduced susceptibility of N.gonorrhoeae to almost all clinically useful antibiotics and also reported cases of multi-resistance. Resistance mechanisms for N. gonorrhoeae can occur through genetic and non-genetic changes. Resistance to cefixime and azithromycin as first-line antibiotics for monotherapy recommended by the World Health Organization (WHO) has been reported from several countries. Genetic changes were reported as the main cause of N.gonorrhoeae resistance to cefixime and azithromycin. Based on the WHO and the United States Centers for Disease Control and Prevention recommendations, countries are increasingly using a combination of cephalosporin and azithromycin for the treatment of gonorrhea. The aim of this review is to analyze genetic variation of N.gonorrhoeae resistance to cefixime and azithromycin. Articles published in English in the last 12 years (from 2010 to 2021) were retrieved from Science Direct, PubMed, Springerlink, Oxford and Nature using relevant searching terms. Mutants of cefixime-resistant N.gonorrhoeae are mediated by mosaic and non-mosaic penA genes encoding penicillin binding protein 2. In addition, mutations in the repressor and promoter genes of mtrR were also found that caused overexpression of the microbial efflux pump. Meanwhile, N. gonorrhoeae resistance to azithromycin reportedly occurs through two strategies, namely overexpression of the efflux pump (mutation of the mtrR codon region) and decreased affinity for antibiotics (single base mutation in the 23S rRNA gene). With the limited choice of antibiotics for the management of N.gonorrhoeae, it is necessary to do regular surveillance for monitoring drug resistance. By understanding the mechanism of resistance, the use of these antibiotics can be rationally optimized.
Nurses' knowledge, attitudes and practices related to physical restraint: the case from Turkey
Authors: OZAKAR AKCA Selen , TURAN Ahu Pınar
Published: May 2023

BackgroundNurses are primarily for the care of patients and should ensure that physical restraint, which has many negative consequences, be applied according to standard practice. Therefore, they should have knowledge about physical restraint and apply physical restraint by observing existing laws and ethical principles. This study aimed to determine the knowledge level, attitude and practices of pediatric nurses on physical restraint and identify the factors influencing physical restraint use.
MethodsA cross-sectional study was conducted involving 150 pediatric nurses working in the pediatric clinic of a training and research hospital. The data were collected with an information form containing the introductory characteristics of the nurses and the Level of Knowledge, Attitudes and Practices of Staff Regarding Physical Restraints Questionnaire. Data were analyzed using the Mann-Whitney U test and the Kruskal-Wallis test.
ResultsOverall, nurses had good restraint-related knowledge with positive attitudes, although the physical restraint practices of nurses were not the best and there were some deficiencies. A statistically non-significant difference was found between age, gender, education status, nurses' work unit, and training status regarding physical restraint on the one hand and knowledge, attitude and practice scores relating to the use of physical restraints on the other (p>0.05).
ConclusionsPediatric nurses' level of knowledge about physical restraint was quite good and their attitudes were positive. However, there were some deficiencies in their practices. Future training should therefore be emphasized to enhance nurses' ethical and sensitive thinking, increase their competence in applying physical restraint and working with patients.

Published: May 2023

Background Acute liver failure (ALF) is a state of rapid and progressive deterioration of liver function. Continuous exposure to chemicals and viruses can increase reactive oxygen species (ROS) which leads to prolonged inflammation due to the production of tumor necrosis factor-alpha (TNF-á) thus inhibiting the production of platelet-derived growth factor (PDGF). The objective of this study was to evaluate the effect of administration of Averrhoa bilimbi L. fruit extract on PDGF levels and TNF-á levels in carbon tetrachloride (CCl4)-induced ALF rats.
MethodsThis study used a post-test-only control group design involving 20 Wistar rats. They were randomized into 4 groups, namely sham, control, T1, and T2. Group T1 was exposed to CCl4 with the administration of A. bilimbi fruit extract at a dose of 500mg/kgBW, while, group T2 was exposed to CCl4 and given A. bilimbi fruit extract of 750 mg/kgBW. On the 15th day, the serum was analyzed to determine the levels of PDGF and TNF-á using ELISA.
ResultsThe highest mean PDGF level in the control group was 146.60±15.36 pg/mL, while the highest mean TNF-á level in group T1 was 40.11±4.44 pg/mL. The One-way ANOVA test showed that there were significant differences in TNF-á (p=0.002) and PDGF (p=0.000) levels between the study groups.
ConclusionThe administration of A.bilimbi L. fruit extract affected PDGF and TNF-á levels in CCl4-induced ALF rats. The present study revealed that A. bilimbi fruits have significant hepatoprotective activity in experimental Wistar rats.

Authors: Yadollahi Mina , Sadegi Kambiz , Afshari Mahdi , Shahraki Mojahed Batool
Published: May 2023

BackgroundLabor pain is one of the most painful experiences in a women's life. One of the methods of pain relief is spinal anesthesia. The purpose of this study was to evaluate the effect of spinal anesthesia with sufentanil on the length of the first and second stages of labor in singleton pregnant women.
MethodsA randomized clinical trial was conducted involving 56 women who had to be at least 37 weeks pregnant with a singleton pregnancy and 20 to 35 years of age, as well as seeking a spontaneous natural delivery. They were randomized into an intervention group (spinal anesthesia with sufentanil) of 28 subjects and a control group (no spinal anesthesia) of 28 subjects. Statistical analysis was performed using SPSS software program 20.0.
ResultsMean duration of stage I of labor was 152.32 ± 92.01 and 187.68 ± 121.01 minutes in the intervention and control groups, respectively (p=0.34), whereas mean duration of stage II of labor in the 2 groups was 15.96 ± 14.26 and 26.43 ± 20.90 minutes, respectively (p=0.06). Twenty five percent of women in the intervention group and 35.71% of women in the control group experienced a long stage I, whereas 21.43% of women in the intervention group and 35.71% of women in the control group experienced a long stage II (p>0.05).
ConclusionThis study suggests that spinal anesthesia with sufentanil does not increase the duration of labor stages. It is recommended that more studies be performed in the future using larger sample sizes to allow for the drawing of solid conclusions.

Authors: Oktaviani Yuri , Dewi Miranti Kartika
Published: May 2023

Research aims: This study explores the importance of information transparency for funders as parties who provide funding to borrowers' projects. It also analyzes information transparency practices in sharia P2P lending.Design/Methodology/Approach: The study used a qualitative case study, focusing on three sharia P2P lending companies in Indonesia. Data were collected through interviews with parties from three sharia P2P lending companies and 11 funders.Research findings: It was found that information transparency is important for funders, increasing their confidence to invest. In addition, based on multiple agency theory, there is information asymmetry between funders and sharia P2P lending borrowers, which can be reduced by information transparency measures from funders, sharia P2P lending, and borrowers based on cost-benefit considerations. Theoretical contribution/Originality: This research explores the application of information transparency in sharia P2P lending companies, which, as far as researchers are concerned, has not been raised in previous studies. In addition, the study builds a conceptual framework of information transparency in sharia P2P lending companies based on multiple agency theory. Practitioner implication: The research has implications for applying information transparency in sharia P2P lending, which can improve information updates and communication from sharia P2P lending to its funders.Research limitation/Implication: The study only focused on three out of the seven sharia P2P lending in Indonesia. Therefore, the differences in business, focus, and other characteristics of the remaining four were not considered.

Authors: Firmansyah Amrie , Kurniawati Lestari , Miftah Desrir , Winarto Tjahjo
Published: May 2023

Research aims: This study examines the effect of allowance for impairment losses (CKPN) on value relevance.Design/Methodology/Approach: This research employed quantitative data using secondary data from banking financial reports derived from www.idx.co.id during 2019-2021. Also, this study used stock price data sourced from www.finance.yahoo.co.id. The use of data for 2020 was due to the first year of PSAK 71 implementation. While data for 2019 were employed to compare the year before the PSAK 71 implementation, and data for 2021 were used to compare the PSAK 71 implementation in the second year. Data testing was then performed utilizing multiple linear regression analysis for cross-section data.Research findings: This study suggests that CKPN was positively associated with the value relevance of earnings in the first year of PSAK 71 implementation.Theoretical contribution/Originality: This research is expected to complement the financial accounting literature on adopting IFRS 9, especially in Indonesia, which is rarely discussed in previous studies.Practitioner/Policy implication: This study is expected to be employed by the Indonesian Financial Services Authority in improving policies on financial stability in the capital market based on applying financial accounting standards.Research limitation/Implication: This study only employed data on banking sub-sector companies listed on the Indonesia Stock Exchange, which were relatively small in number. Future research can therefore use data from all financial companies in Indonesia or banking companies in other countries related to IFRS 9 implementation to compare the test results with this study.

A set of man-made chemicals that have a tendency to poison insects and mammals are organophosphates. Organophosphates are a broad category of chemicals and are widely used insecticides. Now a days, they have various applications such as in agriculture, home, gardens etc. Dimethoate is an insecticide that falls under the category of organophosphates. Dimethoate is a white crystalline solid with robust odor resembling the form of sand or sugar. It was first produced in 1956 to kill or manage insects such as house fly, termites, etc and various countries use it for farming. We have less knowledge about the levels of dimethoate in the environment as, there are no residues found in soil nor it has been found in drinking water. Insecticides that contain Dimethoate are used on various crops such as cotton, tobacco, olives also on various fruits and vegetables. Rapid and fatal poisoning could be caused if it is inhaled or if it comes in contact with skin. The symptoms include headache, sweating, nausea, vomiting, diarrhea, loss of coordination and muscle twitching. Individuals with long term exposure to higher levels of Dimethoate are found to suffer from personality changes including- depression, anxiety, irritability etc. These harmful effects could last for months or years in human central nervous system. Developing fetus are also affected due to the inhalation of gaseous Dimethoate by pregnant women. In this review we are going to discuss about the toxicological aspects and properties of Dimethoate and its effects on humans and the future aspects related to this insecticide.

In this study, carbonized apricot stones and rice husk were utilized as feedstock for the synthesis of CuO-loaded carbonized sorbents for the removal of carbon dioxide (CO2) from gas mixtures. The specific surface area of carbonized sorbents increased with increasing carbonization temperature, resulting in a porous structure with enhanced sorption capacity. The presence of pores and the development of porosity in the sorbents were confirmed by SEM images. CuO nanoparticles were well-dispersed on the surface of carbonized sorbents, and the particle sizes were between 60‒100 nm. Chemical interactions between acidic carbon dioxide and basic copper oxide led to improved adsorption properties. The sorption characteristics of the carbonized sorbents were studied under dynamic conditions, and the results showed that CuO-loaded carbonized apricot stones and rice husk had the maximum sorption capacity for CO2, with efficiencies of 98% and 91%, respectively. These findings indicate that carbonized apricot stones and rice husk can be utilized as low-cost and eco-friendly feedstock for the production of efficient CO2 sorbents.
Dinámica interinstitucional para una tecnología apropiada en el norte argentino
Authors: CAMPRUBI GERMAN , Veroli César , Comparín Julio , Basterra José , Larrea Marcelo , García Carlos
Published: May 2023

El objetivo de este artículo es presentar una dinámica interactiva entre actores organizacionales heterogéneos para resolver la necesidad de mecanización de la remoción de malezas en el norte argentino.

La estrategia metodológica aplicada fue el estudio de un caso con una visión constructivista de la tecnología y específicamente con los enfoques de las Tecnologías Apropiadas (TA) y el modelo de la Cuádruple Hélice. Los conocimientos codificados de la ingeniería fueron una condición necesaria pero insuficiente para la fabricación de una máquina en un período de tres años.

El principal aporte consiste en presentar un producto híbrido como resultado de interacción entre los productores, una Pyme y la Universidad en una red de proximidad a la que se sumó el Estado como ente financiador con funciones de auditor y regulador.

Una implicancia práctica es que la interinstitucionalidad estuvo aterrizada en las escalas individuales de sus representantes. La dinámica relacional entre agentes individuales resultó un punto de palanca para los resultados tangibles e intangibles alcanzados en el territorio.
Los textos manuscritos de Guaman Poma (I). La preparación de la Nueva corónica para la imprenta
Authors: Adorno Rolena
Published: May 2023

Como todos sus lectores lo saben, Felipe Guarnan Poma de Ayala tuvo la esperanza de que su El primer nueva corónica y buen gobierno fuera impreso bajo el patrocinio de Felipe III, rey de España. Al imprimirse su obra se lograría el objetivo de «selebrar y hazer ynmortal la memoria y nombre de los grandes señores antepasados, nuestros agüelos, como lo merecieron sus hazañas» (Guarnan Poma 7 [7]). Solo así podría ser conservada la obra, como su autor lo deseaba, «en el archibo del mundo como del cielo, en el catedral de Roma para memoria y en la cauesa de nuestra cristiandad de nuestra España, adonde rrecide [su] Sacra Católica Real Magestad» (738 [751], 973 [991]). Al contemplar el libro manuscrito que poseemos y tomar en cuenta el anhelo de Guarnan Poma de hacerlo imprimir, quiero cotejar las características físicas del códice de la Nueva corónica y buen gobierno con su contenido, es decir, integrar la discusión de Guarnan Poma acerca del Perú pasado y presente con la evidencia que el manuscrito transmite acerca de su propia construcción y enmienda.
Las sorpresas de la lista de los capitanes
Authors: Szeminski Jan
Published: May 2023

En este trabajo, presentaré reflexiones sobre la sección que trata de los capitanes d los reyes inqas. Para aprovechar las informaciones que contiene, es necesario, como en cualquier otro caso: 1. identificar la procedencia de estas informaciones; 2. depurarlas de sus amplificaciones3; 3. establecer el significado de los hechos de narración presentes en el texto. Intentaré, pues, descubrir el origen de las informaciones contenidas en los textos estudiados y proponer pistas para interpretarlas.
Los orígenes de las informaciones relativas a los conflictos entre los incas y los chancas en la crónica de Felipe Guarnan Poma de Ayala
Authors: Nir Amnon
Published: May 2023

En este artículo me propongo demostrar la hipótesis siguiente: las informaciones que, en la Nueva corónica, se refieren a los conflictos que opusieron a los incas y los _) chancas tienen un doble origen, primero una tradición inca recogida en el Cuzco, segundo una tradición chanca recogida en la región de Lucanas. La primera etapa de esta demostración consistirá en una reconstrucción de estas informaciones.
José Carlos Mariátegui La Chira : Familia e infancia en Huacho
Authors: Rodríguez Pastor Humberto
Published: May 2023

Al comenzar a redactar este artículo tengo la sensación de hacerlo sin haber agotado las posibilidades de hallar más información sobre la niñez de José Carlos Mariátegui, ese cojito genial como lo calificara en cierta ocasión con amistad y ternura su compañero Abraham Valdelomar1 • Y no es que no haya hecho los esfuerzos necesarios. He avanzado discontinuamente desde el verano de 1992 hasta donde he podido tanto en los archivos parroquiales de los pueblos de Sayán y Huaura como en la parroquia de Huacho y en otros archivos (ver fuentes utilizadas).
A la búsqueda de Dios : el proceso ideológico del joven Mariátegui
Authors: Portocarrero Maisch Gonzalo
Published: May 2023

Nuestra primera tarea será caracterizar la sensibilidad del joven Mariátegui. Entendiendo la subjetividad como encrucijada cultural, habrá luego que reconstruir las tradiciones culturales que están presentes en su cosmovisión. Por fin, una vez definida la sensibilidad resulta posible examinar el proceso ideológico del joven Mariátegui, ésto es, identificar las permanencias y rupturas. En este sentido, espero fundamentar la hipótesis de que las continuidades tienen que ver con la valoración de la existencia como aventura, y con la apuesta por la autenticidad; es decir, la fidelidad al principio de buscar siempre la coherencia en un desarrollo lo más radical posible. En síntesis, explorar, correr riesgos, vivir intensamente; pero sin apartarse de los mandatos originales. Mientras tanto la ruptura más importante se da con el paso de una concepción de predominio esteticista -la vida como búsqueda de emociones- a otra concepción fundamentalmente ética, que se expresa en una valoración cada vez mayor de la justicia y, como consecuencia, en la vehemencia por hacer de ella una realidad. En estas circunstancias la única forma de seguir siendo consecuente consigo mismo es el distanciamiento y crítica del orden aristocrático, junto con la solidaridad con los oprimidos. Todo ello significa convertirse en protagonista, dejar de ser espectador. En este momento de su evolución el encuentro con las ideas socialistas le significa comenzar a pensar en un proyecto colectivo, que lo incorpore pero lo trascienda. Sin embargo nunca dejará Mariátegui de cultivar sus disposiciones artísticast. Su sensibilidad e intuición enriquecen su captación de la realidad, hacen posible un contacto primordial que fundamenta su originalidad.
«La Noche», el periódico perdido de Mariátegui
Authors: Gargurevich Juan
Published: May 2023

Estudiar exhaustivamente la vida y obra de un hombre parece imposible. Hay múltiples ejemplos que muestran que aquellos que aseguraron saber todo sobre alguien fueron después sorprendidos por informaciones recién descubiertas, textos inéditos, cartas furtivas. A esta regla no escapa José Carlos Mariátegui, cuya vida y obra viene siendo objeto de observación sistemática prácticamente desde su niñez, porque en esa etapa de vida estaba cuando ingresó a trabajar al diario La Prensa. Quedan aún, insistimos, aspectos poco conocidos de la obra del famoso periodista y que probablemente nunca lleguemos a conocer a cabalidad, Es el caso del periódico humorístico La Noche, que Mariátegui editó en marzo de 1917 y del que no se conserva -que sepamos- ningún ejemplar.
José Carlos Mariátegui en la Universidad Católica
Authors: Hampe Martínez Teodoro

En más de una oportunidad el Amauta declaró, con inocultable timbre de orgullo, su condición de autodidacta. Aunque su educación formal -paralizada debido a sus frágiles condiciones de salud- abarcó sólo los primeros dos años de primaria en una escuela de Huacho, su decidida vocación por las lecturas y el aprendizaje le permitió componer una obra vasta y dispersa, memorable no sólo por la trascendencia de sus formulaciones ideológicas, sino también por la finura de sus creaciones y de sus ensayos de crítica literaria y artística. La revista bonaerense La Vida Literaria editó póstumamente una carta de Mariátegui, de 1928, en la que revelaba estos puntos: «Me matriculé una vez en Letras en Lima, pero con el solo interés de seguir un curso de latín de un agustino erudito. Y en Europa frecuenté algunos cursos libremente, pero sin decidirme nunca a perder mi carácter extra-universitario y tal vez sí hasta anti-universitario».
Pensar la historia, hacer la historia. La aventura de Mariátegui
Authors: Gutiérrez Gustavo
Published: May 2023

Con acierto los organizadores de este encuentro lo han titulado «La aventura de Mariátegui». Su vida y su obra lo fueron, en efecto, y él tuvo clara conciencia de ello. Su aventura es, además, de alguna manera la nuestra. Asistimos hoy a grandes cambios en el panorama social, económico, político, cultural, tanto a nivel internacional como nacional. Ellos se manifiestan en el derrumbe del socialismo real, la fuerza ideológica -y, tal vez, la debilidad práctica- de un cierto liberalismo, brotes autoritarios con algún respaldo popular, una nueva etapa de la modernidad. Todo eso hace de nuestros días un tiempo que no es el de Mariátegui, pero entre ambos se presentan analogías que resultan dicentes y fecundas para nosotros.
Mariátegui : estética y modernidad
Authors: Castro Carpio Augusto
Published: May 2023

Los escritores españoles de la llamada Generación de 1898 ejercieron cierto influjo sobre sus homólogos de la América hispanohablante, si bien ocurrió así mismo_ lo inverso: el centroamericano Rubén Darío influyó decisivamente sobre la aludida generación, a un punto tal que algunos lo consideran integrante de ella. Tal vez sería más exacto decir, entonces; que entre ambos se produjo una interacción recíproca.
Mariátegui, Fukuyama y el fin de la historia
Authors: Klaiber, Jeffrey L.
Published: May 2023

Hacer una comparación entre José Carlos Mariátegui y Francis Fukuyama, autor del célebre artículo sobre el fin de la historia, parecería consistir, a primera vista, en un ensayo de contrastes, o bien, una comparación de polos opuestos. Muchos vieron en el artículo de Fukuyama, escrito en 1989, una especie de himno de alegría al triunfo del liberalismo capitalista ante al evidente fracaso del comunismo en la Unión Soviética y la Europa Oriental1. Posteriormente, Fukuyama desarrolló su pensamiento más ampliamente en su libro, El Fin de la historia y el último hombre2• La caída de la Unión Soviética, un hecho que ocurrió después de su artículo, sirvió para confirmar sus tesis originales. Entre este portavoz que escribe acerca de las bondades del capitalismo liberal en la última parte del siglo veinte, por un lado, y de otro, José Carlos Mariátegui, el portavoz de un nuevo socialismo en emergencia en América Latina que escribía en los años 1920, no parece haber mucho lugar para una comparación.
