White blood cell count and ratıo changes ın newborns after granulocyte colony-stımulatıng factor treatments
Authors: Buyukeran Melek , Yiğit Şule , Çelik Hasan Tolga , Yurdakök Murat
Published: October 2021

Background Granulocyte-colony stimulating factor (G-CSF) is frequently used to treat neonatal neutropenia. There is a paucity of data in the literature on when immature to total neutrophil ratio (I/T ratio) can be accurately used as a sepsis marker after G-CSF therapy, as well as when I/T ratio returns to normal values expected in newborns who did not receive G-CSF.

Objective To investigate changes in white blood cells counts and ratios in neonates with neutropenia before and after G-CSF therapy.

Methods This retrospective study included newborns admitted to the NICU of Hacettepe University Ihsan Dogramaci Hospital, Ankara, Turkey, between 2005 and 2017 who received G-CSF therapy for neutropenia. Subjects underwent complete blood counts on the day before receiving G-CSF therapy (day 0) as well as days 1, 2, and 3 after treatment; I/T ratios were recorded from peripheral smears.

Results Twenty-eight neonates were included in the study. Subjects’ median gestational age (interquartile range 25–75%) was 32.6 (29.7–37.6) weeks, and median birth weight was 1,630 (1,040–2,980) g. On day 3, there were significant increases in white blood cell counts compared to day 0. There were statistically significant elevations in the I/T ratios between day 0 and day 1 and between day 0 and day 2. On day 3, the I/T ratio decreased, but was not significantly different between day 0 and day 3.

Conclusion The changes in I/T ratio observed after G-CSF treatments in our study suggest that the I/T ratio can be used as a reliable sepsis marker starting 72 hours after G-CSF administration. However, I/T ratio is significantly affected within 72 hours of G-CSF administration, and therefore, is unreliable as a sepsis marker during that period.

Authors: Malisie Ririe Fachrina
Published: October 2021

A number of coronavirus disease-19 (COVID-19)–related myocarditis cases have recently been reported. Myocarditis is an inflammatory disease of the heart characterized by inflammatory infiltrates and myocardial injury without an ischemic cause.1 While multiple etiologies exist, the major cause appears to be related to viral illnesses. Clinical presentations vary from asymptomatic to sudden unexpected death.2 Acute heart failure due to COVID-19-related acute myocarditis has been associated with multisystem inflammatory syndrome, mimicking Kawasaki disease. 3 Here, we report a case of a 1-month old girl with reactive anti-COVID–19 IgG, presenting with arrhythmia following the shortness of breath during hospitalization. Respiratory distress and myocarditis progressed to multiple organ failure and the patient died on her third day in the PICU.

Published: October 2021

Background Post-chemotherapy febrile neutropenia results in high morbidity and mortality in children with malignancy. Many prognostic factors, such as microorganism patterns, as well as the use of antibiotics and antifungals can affect the outcomes. However, limited study is available in Indonesia.

Objective To determine the microbial profiles, antibiotic sensitivity, and other factors that influence mortality from febrile neutropenia in pediatric malignancies with infections.

Methods This retrospective cohort and descriptive study of 180 children with 252 episodes of neutropenic fever was done in Cipto Mangunkusumo Hospital, Jakarta, between 2015 and 2017. Medical history of possible predictive prognostic factors, including microorganism patterns and antibiotic sensitivity, were recorded. Prognostic factors were analyzed using multivariate logistic regression tests.

Results The most common bacteria was Gram-negative (54.5%), while  Candida sp. was the most common fungal infection (82.5%). Klebsiella sp. was mainly sensitive to amikacin (85.71%), while Pseudomonas aeruginosa was sensitive to ceftazidime (75%), as well as amikacin and gentamicin (100% sensitivity in combination). Staphylococcus sp. was mainly sensitive to amoxi-clav and ampi-sulbactam (76.9%). Almost all fungal groups were susceptible to fluconazole, ketoconazole, voriconazole (80-100%). Prognostic factors that increased mortality risk were central venous cannulation (RR 1.947; 95%CI 1.114 to 3.402), wasting (RR 1.176; 95%CI 1.044 to 1.325), severe wasting (RR 1.241; 95%CI 0.975 to 1.579), and hematologic malignancies (RR 0.87; 95%CI 0.788 to 0.976).

Conclusion Central venous cannulation and wasting are significant prognostic factors of increased mortality in children with febrile neutropenia. Gram negative bacteria along with Candida sp. is the most common pathogen in such condition.

Published: October 2021

Introduction: The relationship that socio-familial and non-cognitive variables have on students in regards to their academic performance is a very important element for success in Secondary Education. In this study the influence of non-cognitive variables (academic self-concept, self-efficacy and perceived family affective support) and socio-familial variables (educational level and expectations of each parent) on the academic performance of secondary school students were analysed. Method: Students were grouped according to their accumulated socio-familial risk index (at-risk students, n = 305; not-at-risk students, n = 991). To measure the variables, the scales What do you think of yourself, General Self-Efficacy and Perceived Family Support were used. Socio-family variables were measured with an ad hoc questionnaire, and academic performance with the end-of-course evaluation scores. Results: The receiver operating characteristic curve showed a decrease in students’ academic performance from three or more accumulated risks. Structural Equation Modelling (SEM) was performed for each group. The results showed that for at-risk students, academic performance was mainly determined by two variables: academic self-concept and self-concept; in contrast to the not-at-risk students in which self-efficacy was the one that had the greatest effect on performance. In both groups, the parents’ expectations were the family variable with the highest incidence being performance, although, for the at-risk group, the effect was greater. Conclusions: The relevance of the identification of non-cognitive and socio-familial variables on the academic performance of at-risk students in regards to secondary education due to socio-familial factors is discussed.

Published: October 2021

Up to now, a great deal of research investigations on lithium ion conductors has been carried out, because they are potentially utilized in the solid electrolytes of the batteries and the electrochemical devices. However, in order to elaborate new ecological batteries of lithium, it becomes primordial to study and understand the properties of transport of the lithium electrolytes using eco-friendly solvents, with view perhaps to find out the best electrolyte for such devices. In fact, the electromotive forces (EMFs) of lithium chloride electrolyte in the hydrogen-bonded solvents glycerol, were measured using the concentration cells (CCs) 0.005/0.05 and 0.05/0.5. Then the transport numbers of the lithium-ion were deduced by means of the Nernst equation in combination with the Debye-Huckel limiting law. Whilst the activation energy values were calculated from the parameters of the fitting of the transference number data to the empirical power law, yielding a regression coefficient of 95.9% for the most concentrated concentration cell. The structure and interactions in the lithium electrolyte solution were studied by vibrational Infra-Red spectroscopy. The experimental data were discussed and compared to those obtained previously, using impedance spectroscopy of glass-forming glycerolate lithium electrolytes for the same purpose. Despite the enormous difference between their viscosities; glycerol shows similar activation energy (i.e. 31.40 kJ.mol–1) with water (i.e. 31.73 kJ.mol–1), in particular at very low concentration, confirming both solvents being hydrogen-bonded. Besides, this study suggests the utilization of the glycerol-lithium ion electrolyte for future conception of ecological lithium-ion battery, rather than those using ion electrolyte polymer currently on the market. Similarly to relaxation and conductivity, the transport number data suggests that the diffusion of conformational states is also monitoring the overall lithium ion transport mechanism.
Effect of Hydrogen Peroxide on Hydrogen Production from Melon Fruit (Cucumis melo L.) Waste by Anaerobic Digestion Microbial Community

Published: October 2021

Biohydrogen (H2) production has the potential to provide clean, environmentally friendly, and cost-effective energy sources. The effect of increasing oxidative stress on biohydrogen production by acid-treated anaerobic digestion microbial communities was studied. The use of varying amounts of hydrogen peroxide (H2O2; 0.1, 0.2, and 0.4 mM) for enhancing hydrogen production from melon fruit waste was investigated. It was found that H2O2 amendment to the H2-producing mixed culture increased hydrogen production. Treatment with 0.4 mM H2O2 increased cumulative H2 output by 7.7% (954.6 mL/L), whereas treatment with 0.1 mM H2O2 enhanced H2 yield by 23.8% (228.2 mL/gVS) compared to the untreated control. All treatments showed a high H2 production rate when the pH was 4.5 – 7.0.  H2O2-treated samples exhibited greater resilience to pH reduction and maintained their H2 production rate as the system became more acidic during H2 fermentation. The application of H2O2 affected the volatile fatty acid (VFA) profile during biohydrogen fermentation, with an increase in acetic and propionic acid and a reduction in formic acid concentration. The H2O2 treatment positively affects H2 production and is proposed as an alternative way of improving H2 fermentation.

Cost-Effective Remote Operated Vehicle
Authors: Smolder Zachary , Yi Jingang
Published: October 2021

Remote operated vehicles (ROVs) are robotic submersibles controlled typically by a person at the surface of a water body. ROVs can be applied to surveillance, environmental, and data recording jobs or tasks. The vehicle design may be modified to remove or add additional capabilities depending upon the specific purpose of the ROV. In this paper, we explore using remote operated vehicles as a cheap and affordable water exploration platform. ROV’s high cost is a prohibitive barrier to entry, preventing widespread adoption of ROV for personal, research, and conservation uses. To address this problem, our paper explores a cost effective ROV with video capturing and directional control capabilities. Using state-of-the-art robotic technologies, a cost-effective competitive ROV is designed and constructed. This ROV was tested to a depth of 7 meters and has the potential to reach depths of up to 30 meters per its design.
Role of Autophagy in Phosphatidyl- Glycerol Facilitated Cholesterol Clearance from the Endolysosomal System of Npc-1 Deficient Cells
Authors: Allada Tamara , Ilnytska Olga , Storch Judith
Published: October 2021

Niemann Pick Type C (NPC) Disease is a rare lysosomal storage disorder in which one of the genes that codes for either the NPC-1 or NPC-2 pro-tein is mutated, causing cell lysosomes to accumu-late cholesterol and lipids. Previous studies discov-ered that a unique late endosomal/lysosomal phos-pholipid, lysobisphosphatidic acid (LPBA), is in-volved in cholesterol clearance from late endo-somes. It has also been shown that exogenous treat-ment of the NPC-1 deficient cells with LBPA’s precur-sor, phosphatidylglycerol (PG), leads to LBPA enrich-ment and subsequent endolysosomal cholesterol clearance. Autophagy is a mechanism of cellular clearance in the endolysomal system and we are in-terested to see if it is a partial route in cholesterol clearance during PG treatment of NPC-1 deficient cells. To do so, we silenced the gene that codes for an essential protein in the autophagy pathway, mak-ing the cells autophagy deficient. We then treated the cells with PG, measured the amount of choles-terol clearance in those cells, and compared it to cells with normal autophagy. We found significantly less cholesterol clearance by PG in cells with defec-tive autophagy, confirming that autophagy is in-volved as a partial route in cholesterol clearance dur-ing PG treatment, but not enough of a difference to conclude that it is a major underlying mechanism.
Topic Modeling and Analysis: Comparing the Most Common Topics in 19th-Century Novels Written by Female Writers
Authors: Rha Lauren , Silver Sean
Published: October 2021

Women authors from the 19th-century have had a profound impact on the literary world due to their critical approach to and inclusion of various so-cial phenomena within their work, such as women's rights, sexuality, and human psychology. This paper seeks to contribute to the discussion by quantifying thematic similarities in eight select novels by various female authors of the 19th-century. These novels were chosen due to their contribution to literature and their popularity, common use in college courses around the world, and the prominence of the female authors. This study included utilizing a programming environment known as R Studio to perform a topic model. Performing a topic model allowed for the discernment of ten main themes or topics that can be generally seen across all eight selected novels, and by extension, 19th-century literature by female authors. The research found initial evidence to sup-port the general understanding of said literature as an endeavor of the themes of social critique and in-dividual consciousness; however, the results were not absolute in conclusion because of the limited size of the corpus. A larger corpus of documents (novels) is necessary to reach further conclusions.

Vitamin D receptor (VDR) is a transcription factor that mediates calcium absorption by intestinal epithelial cells. Although calcium absorption is ca-nonically thought to occur only in the small intestine, recent studies have shown that VDR activity in the co-lon alone is sufficient to prevent calcium deficiency in mice. Here, we further investigate VDR activity in the colon. We assess VDR-DNA binding in mouse duodenal crypt, duodenal villi, and colonic epithelial cells using Chromatin Immunoprecipitation se-quencing (ChIP-seq). We find that most VDR-respon-sive elements are common to all intestinal epithelial cells, though some VDR-responsive elements are re-gionally-enriched and exhibit greater VDR-binding affinity in either duodenal epithelial cells or colonic epithelial cells. We also assess chromatin accessibil-ity in the same three cell types using Assay for Trans-posase-Accessible Chromatin sequencing (ATAC-seq). By integrating the VDR ChIP-seq and ATAC-seq data, we find that regionally-enriched VDR-re-sponsive elements exhibit greater chromatin acces-sibility in the region of their enrichment. Finally, we assess the transcription factor motifs present in VDR-responsive elements. We find that duodenum- and colon-enriched VDR-responsive elements exhibit different sets of transcription factor motifs other than VDR, suggesting that VDR may act together with dif-ferent partner transcription factors in the two re-gions. Our work is the first investigation of VDR-DNA binding in the colon and provides a basis for further investigations of VDR activity in the colon.
Characterizing an Alternatively Spliced Variant of Chemokine Receptor 2 in Painful Diabetic Neuropathy
Authors: Soltys Justine , Yu Lei
Published: October 2021

Prior research efforts have demonstrated a link between neuroinflammation and the progres-sion of Painful Diabetic Neuropathy (PDN), a chronic cascade of nerve damage that presents as tingling, numbness, hypersensitivity to touch, or intense pain. Current treatments are focused on pain manage-ment, serving to temporarily mask these symptoms without repressing or slowing nerve damage. The chemokine-receptor system has been closely stud-ied for its role in perpetuating neuropathic pain, alt-hough its precise mechanistic involvement remains unclear due to the network’s complexity. Because of its likely role in regulating neuropathic pain, target-ing CCR2 may be the key to effective treatment of PDN.Alternative splicing of CCR2 leads to two dis-tinct isoforms with different C-terminus sequences, CCR2A and CCR2B. The present study was intended to differentiate between these isoforms through spe-cific primer design, selection of optimized pairs, RT-PCR, and amplicon sequencing to verify the PCR products. However, the study has revealed a third, previously unreported isoform, CCR2C, due to evi-dence of alternative splicing and both the absence and insertion of parts of A and B. In the long term, we predict that the relationship between CCR2’s alternatively spliced transcript variants will lead to a distinct pattern of isoform prevalence in individuals suffering from PDN. Discerning the genetic profiles of patients with PDN and healthy individuals will clar-ify the complex mechanism driving CCR2’s intracel-lular interactions and offer more effective therapeu-tic options.
Noble shape, humble metals. Bronze and silver shield-head and snake-head rings of Roman era Scandinavia
Authors: Rundkvist Martin
Published: October 2021

Gold snake-head rings are a famous and much studied artefact group of the Late Roman Period in Scandinavia. But before and during their heyday, women in the same areas were occasionally buried with shield-head and snake-head rings made of silver or bronze. This paper surveys the material and traces the origin of these designs from the Wielbark Culture in coastal Poland about AD 100. The early shield-head rings probably arrived across the Baltic with the women who wore them. After the AD 210s, non-gold rings are a feature of the gold snake-head rings’ core production and distribution area on the Baltic Islands and south-east mainland Sweden. The women who wore them were not tribal royalty, but enjoyed comfortable economic means and had the right to display this top-level symbol in more affordable materials.
Indian Fighters in the Philippines
Authors: Aune Stefan
Published: October 2021

This article explores the connections between the violence that accompanied U.S. continental expansion in the nineteenth century and the Philippine-American War, which began in 1899 after Spain ceded the Philippines to the United States following the Spanish-American War. Perhaps geographic distance has served to mask the temporal proximity of these linked periods of U.S. expansion, because this is a connection that has remained largely unexplored in the historiography. Rather than viewing 1898 as a caesura marking the separation between the continental and global phases of American empire, this article explores continuities through an examination of the interaction between imperial culture and military violence. Some U.S. soldiers in the Philippines drew directly on their experiences in wars with Native people, while others narrated their time in the Philippines as an “Indian war” and validated their actions by discursively positioning themselves and their troops as “Indian fighters.” The Indian Wars were translated, through the actions, imaginations, and writing of U.S. soldiers, politicians, and journalists, into a flexible discourse able to travel across space and time. These frontier resonances became one of several structuring narratives that sought to racialize Filipinos in order to justify the war and occupation.

Nowadays, the worldwide primary reasons of long-term disability is stroke. When the blood supply to your brain is interupted and reduced, stroke occurs as it depriving brain tissue of nutrients and oxygen. In the modern world, advanced technology are revolutionizing the rehabilitation process. This research uses mechanomyography (MMG) and machine learning models to classify the elbow movement, extension and flexion of the elbow joint. The study will aid in the control of an exoskeleton for stroke patient's rehabilitation process in future studies. Five volunteers (21 to 23 years old) were recruited in Universiti Malaysia Pahang (UMP) to execute the right elbow movement of extension and flexion. The movements are repeated five times each for two active muscles for the extension and flexion motion, namely triceps and biceps. From the time domain based MMG signals, twenty-four features were extracted from the MMG before being classified by the machine learning model, namely k-Nearest Neighbors (k-NN). The k-NN has achieved the classification accuracy (CA) with 88.6% as the significant features are identified through the information gain approach. It may well be stated that the suggested process was able to classify the elbow movement well

Published: October 2021

Effects of the wood species, number of teeth, and adhesive type were studied relative to the moment capacities of box joints under tension and compression loadings, which is commonly used in case type solid wood furniture. For this purpose, L-type specimens were prepared from Scotch pine (Pinus sylvestris L.), poplar (Populus sp.), and fir (Abies sp.). Polyvinyl acetate (PVAc) and polyurethane (PU) adhesives were used in the preparation of joints. Tension and compression tests with 360 samples were performed under static loading. According to the results, the highest moment capacities were obtained for Scotch pine under tension, and poplar specimens under compression. With respect to the number of teeth, the highest moment capacities were obtained with 12-tooth joints under both tension and compression loadings. For adhesive types, the specimens glued with PVAc gave better results in both tension and compression. In manufacturing of solid wood based case-type furniture, the higher number of teeth resulted in a slightly better performance; however, the results with the 4-tooth structure was not too far from 8-tooth. Furthermore, it was concluded that Scotch pine as a substance and PVAc as adhesive could be recommended.

MACROCHONDRULES IN SOME CHONDRITES: 2. GENETIC ASPECTS
Authors: Semenenko V.P. , Girich A.L. , Shkurenko K.O. , Kychan N.V.
Published: October 2021

An electron microscopic and microprobe study of the macrochondrules from the chondrites Allende CV3, Krymka LL3.1, Saratov L4, "Velyka Balka" L4-5 and Château-Renard L6 allow to clear some aspects of their formation. The main of them are following: 1) The texture and mineral composition of the majority of the macrochondrules does not differ from those of ordinary chondrules, thus indicating a similarity in formation conditions, 2) It is shown for the first time that the SiO2/MgO and FeO/(FeO+MgO) ratios of the fine-grained rims of the macrochondrules and one`s of chondrules in the Krymka meteorite are well correlated. This indicates to their coexistence in the same dusty environment of the protoplanetary nebula, 3) The unique characteristics of the two firstly found macrochondrules allowed us to detail conditions of their formation and existence in the protoplanetary nebula. A polyzonal graphite-bearing macrochondrule from the Krymka meteorite formed by accretional growth in a mineralogically variable dusty environment. Its complex evolutional history involved remelting and selective evaporation of the macrochondrule surface layer, accretion of an environmental dust, late formation of a fine-grained rim and migratory intrusion of an organic protomaterial and finally a metamorphic event that produced graphite. The melted surface of a macrochondrule from the Allende chondrite was notably affected by high-energy processes and instantaneous cooling in the protoplanetary nebula, 4) The rarity of macrochondrules in chondrites compared to typical chondrules is probably related to their priority destruction. This was caused by permanent movement and collision between them and other solid objects in the pre-agglomeration period of meteorite development.
GEOCHEMICAL FEATURES OF POST-PYROGENIC CHANGES OF POLISSYA SOILS (LOW FIRE)

Published: October 2021

Geochemical post-pyrogenic soil changes are one of the most important factors in determining the state of the forest ecosystem. For the first time the content of microelements (Hg, As, Ba, Mg, Mn, Mo, Cd, Co, Cr, Cu, Pb, Zn, V, Ni) in post-pyrogenic sod-podzolic soils under the pine forest of Zhytomyr Polissya (Ukraine) was determined by the ICP-MS method. The study is based on a comparison of the content of trace elements in the sod-podzolic soils of the background area and burnt areas (grassland fire in 2019). The analysis of microelements in the soil profile of the burned and background areas to a depth of 10 cm (after 1 cm) and set the limit - 3-5 cm (humus-eluvial horizon), after which you can record the accumulation or scattering of elements after a fire on the surface. By calculating the percentage change (relative to background soils), intensive accumulation (more than 20%) of elements in post-pyrogenic soils - Cu, Ni, Co, V and moderate accumulation (up to 10%) - Pb, Mo, Mg, Ba, Cr and intensive scattering - Hg, As, Cd, Zn, Mn. The increase in the pH of post-pyrogenic soils (from 4.2 to 7.5) was determined, spatial map-schemes were constructed, due to which the direction of the fire was revealed - from the south-east to the north-west. The change of the content of ionic forms of metals (Cu, Pb, Zn, Mn) in the soil solution at different pH values (from 4 to 8 with a step of 0.2) is modeled (PHREEQC program) and the current trend is revealed: Pb - linear dependence, Cu, Zn, Mn is polynomial. The pH limits are calculated, where there are free forms of metals that enter the plants: Pb 3.9-8.2; Zn 5.5-7.5; Cu 5-8.2; Mn 5-11.5. The post-fire transformation of soils was revealed, which is expressed in the increase of pH (before the fire - 4.2-4.8; after the fire - 6.5-7.2; a year after the fire - 4.5-5.5). The obtained results confirmed the need for geochemical monitoring of post-pyrogenic soils for ecosystem restoration and plant biodiversity.

Published: October 2021

This paper aims to promote the implementation of the concept of strengthening moderate Islam through democratic learning in Islamic elementary schools. The ease of internet access and remote communication, as the effect of globalization in the field of technology, can be used to gain any information needed, including the Islamic knowledge that can be freely learned without teachers. A literature study was employed to describe the data related to the internalization of moderate Islam and democratic learning. The findings demonstrate that moderate Islam (tawasuth) is a life principle that upholds justice in social life. The values of moderate Islam can be internalized in the school curriculum as a reinforcement starting from the elementary school level through implementing democratic learning. This application can be carried out through various methods such as discussion, question and answer, group work, and simulation. The implementation of democratic learning encourages communicative relationships between teachers and students, fosters friendship, and enhances the value of ‘ukhuwah’ (good relations). Furthermore, these methods emphasize student-centered learning. This study also illustrates that democratic learning provides a wide array of opportunities for students to creatively and critically express their ideas and thoughts in their own learning styles.

In the context of unregistered marriage, it can be defined as “a form of marriage based on religious law or custom, as well as one that is not announced to a crowd and is not registered with the marriage registry”. This paper discusses literacy in Islamic law and positive law on unregistered marriages. Positive law studies on  unregistered  marriages   are  carried  out  on  the   essence  of  the Law of the Republic of Indonesia and Government Regulations. According   to  Indonesian   law,   sirri   marriage   is a  marriage   that is not based on the principle of legality. In Islam, the study of unregistered   marriage   was   based   on   Qur’an   and   hadith.   This means that it is not legally binding. A marriage that is in accordance   with   the  pillars  and   conditions   of   marriage   is valid  under  Islamic law, as are   marriages   performed   in   sirri marriages, as defined in Indonesian law.

This study describes the in vitro seed germination and micropropagation of Plukenetia volubilis (sacha inchi), an oilseed crop rich in omega-3 fatty acids, with health benefits and several industrial applications. Seed germination was evaluated in different culture media (MS and 1/2 MS), seed coat presence/absence and culture temperature (18 °C and 28 °C). Micropropagation was performed using axillary bud development (ABD) on nodal segments from in vitro seedlings. KIN, BAP and 2-ip were evaluated for ABD, and the effect of modified MS in 453 mg L-1 CaCl2 and 351.62 mg L-1 MgSO4 on ABD and shoot survival was assessed to improve the process. Finally, six treatments were evaluated to optimize ABD and shoot leaf formation. Seed germination of 91.6 % was achieved in MS at 28 °C when the seed coat was removed. ABD was obtained in 45 % and 40 % with 0.4 mg L-1 KIN and 0.6 mg L-1 2-ip, respectively, with the least CAL. The modification in 453 mg L-1 CaCl2 then allowed 76 % ABD and 82 % explant survival. ABD response was optimized to 95 % and 2.45 leaves with MS medium + CaCl2 modification + 10 % coconut water + 0.4 mg L-1 KIN. The same results were obtained by replacing the latter with 0.6 mg L-1 2-ip. Rooting was achieved in MS without PGR, and acclimatization was successful. The results indicate that plant production via germination and vegetative propagation is effective for commercial purposes.
Ensaios para a participação popular: o Plano Diretor de Curitiba-PR entre permanências e rupturas
Authors: Cestaro Lucas Ricardo , Cestaro Lilian
Published: October 2021

A construção de cidades com espaços urbanos mais democráticos segue entre os desafios do planejamento urbano contemporâneo. No Brasil, a democratização destes espaços passa pela institucionalização da inserção da participação popular no processo de planejamento da cidade, instituído pela Constituição Federal de 1988 e pelo Estatuto da Cidade. Analisando a experiência do planejamento e da cultura técnica urbanística em Curitiba/PR, questiona-se se a participação popular foi incorporada no processo de revisão do Plano Diretor, no contexto pós-constituinte. Para tanto, a análise consiste em verificar, através de pesquisa exploratória, revisão bibliográfica e de documentos oficiais (como atas, listas de presença, cartilha e folder de divulgação), o recente processo de revisão do Plano Diretor, ocorrido em 2014, focando o olhar sobre a questão da participação popular. Apresenta-se assim, numa perspectiva comparada com processos anteriores, a análise sobre eventuais permanências com a cultura técnica do planejamento de Curitiba, imposta pelo discurso tecnocrata, vigente desde a criação do IPPUC na década de 1960, e as rupturas, em detrimento dos princípios da gestão democrática e participativa, introduzidos pelo Estatuto da Cidade em 2001.
Transformações socioespaciais pela Unidade de Polícia Pacificadora (UPP): a favela do Vidigal, Rio de Janeiro
Authors: Glitz Mayrink Priscilla , H. Tardin-Coelho Raquel
Published: October 2021

O artigo busca compreender como estratégias sociopolíticas, que não intervenham diretamente no espaço físico, implicam em uma reordenação do entorno construído junto com transformações de práticas sociais locais. Como caso de estudo são analisados os processos de transformação socioespacial desencadeados pela implantação da Unidade de Polícia Pacificadora (UPP) na favela do Vidigal, na cidade do Rio de Janeiro. O ponto de vista do morador local é adotado para analisar como estes processos reforçam (ou não) as dinâmicas de exclusão social e segmentação espacial às quais as favelas, historicamente, foram submetidas, e quais as consequências na atualidade. Metodologicamente, a pesquisa, qualitativa, compreende: 1) reconhecimento do Vidigal antes da implantação da UPP: espaço construído – edificações, vias e demais espaços livres –, e espaço vivido – práticas e valores cotidianos, relações entre moradores e entre esses e a UPP; 2) Compreensão do programa da UPP; e 3) reconhecimento dos processos de transformação socioespacial pós-UPP. Verifica-se que as transformações socioespaciais reforçam o panorama de exclusão social e segregação espacial da favela pela incorporação da favela às dinâmicas de mercado (do solo e de serviços) da cidade. Soma-se a isso, a constatação da decadência do programa nos anos subsequentes e o agravamento do panorama estudado.
Planificación urbana, barrios y creación de comunidad, Guanajuato, México
Authors: Ordaz Zubia Velia Yolanda , Ayala Macías Elvia Guadalupe , Puy y Alquiza María Jesús
Published: October 2021

El presente artículo se conforma por tres apartados centrales. En los dos primeros se realiza una revisión de dos constructos teóricos multidimensionales: la estructura urbana y la conceptualización y atributos tradicionales del barrio. Habrá que destacar que, en ambas definiciones, se conjuga el interés por explicar las interacciones socioespaciales que se generan entre el territorio y sus habitantes; es justo al imbricar estas nociones que se genera una propuesta de planificación en la que se refrenda la creación y desarrollo de comunidades desde su unidad de sociabilidad básica. Dicha proposición se sustenta en la realización de investigaciones y proyectos urbanos llevados a cabo durante poco más de una década (2010-2020) en la ciudad Patrimonio de la Humanidad de Guanajuato, Guanajuato, México, estos proyectos se exponen en el tercer y último apartado. Así, el presente artículo busca reformular la planeación urbana tradicional, concluyendo con el planteamiento de una estrategia metodológica en la que se logre integrar las prácticas cotidianas y la cambiante configuración del espacio que se han suscitado desde el Siglo XVI hasta nuestros días
“La vecindad”, exclusión urbana en Centros Históricos. Pobreza y migración en barrios de Puebla (México)
Authors: Hernández Sánchez Adriana , De la Torre Sánchez Christian Enrique
Published: October 2021

Esta investigación plantea que “las vecindades” de los barrios, localizadas en la periferia de los Centros Históricos, son producto de la exclusión urbana existente desde el origen de las ciudades, tal es el caso de Puebla. Las vecindades son viviendas colectivas que se construyeron como resultado de la segregación social, a partir de la delimitación urbana entre la ciudad central de los españoles y los barrios indígenas de los alrededores. A pesar del deterioro físico, son inmuebles que responden a las necesidades actuales de algunos grupos sociales, que conservan la densidad habitacional de la zona y mantienen la vitalidad e identidad de la ciudad histórica a través de las prácticas sociales de sus habitantes. A partir de los testimonios de vecinos, se exponen ventajas y desventajas de vivir en colectividad; se identificaron algunas dinámicas y modos de vida que hay en las vecindades, su estado de conservación y la ocupación de espacios de uso común, como sanitarios, lavaderos y patios. El artículo finaliza con una propuesta para el fomento y conservación de estos espacios, donde los propietarios y residentes tengan un papel primordial en la permanencia de la vida comunitaria del barrio y la ciudad
Inversiones indígenas, Covi-cho y algunos tips anti Antropoceno
Authors: Medrano Celeste , Charole Auden
Published: October 2021

El espíritu de este ensayo es poner en diálogo las nociones de ‘cuerpo’ y ‘alma’ narradas por los indígenas qom del Gran Chaco Argentino y los sucesos desplegados por la actual pandemia de Sars-Cov-2. Iniciaremos nuestro desarrollo contemplando la escena de la llegada de los españoles a América y la inversión que hoy se presenta respecto a los diacríticos expresados en aquella época. Con el fin de ‘familiarizar’ al virus, lo llamaremos ‘Covi-cho’ y lo situaremos en tensión con la entidad patogénica que los indígenas componen. A su vez examinaremos diversos fines de mundo experimentados por los colectivos indígenas de Argentina. El objetivo será detallar qué nos enseñan estos otros fines de mundos con sus devenires particulares y cuáles son los tips que, poniendo en tensión una multiplicidad de cuerpos e interioridades humanas y no-humanas, podríamos agregar a los ya consabidos y promocionados desde las esferas estatales.
Serpentear: énfasis y preguntas en el pasado amazónico
Authors: Mora Santiago
Published: October 2021

Hace más de cien años nació el interés de los investigadores por la Amazonia. Desde sus inicios los contextos desde los cuales los estudiosos hacen las preguntas que guían su trabajo y los supuestos sobre los cuales los mismos se apoyan han variado. Este artículo identifica y hace un breve bosquejo de los énfasis y las preguntas más destacadas en el campo de la arqueología amazónica, examinándolas desde su relación con la antropología. No se trata de una revisión exhaustiva del material publicado, más bien de una síntesis introductoria a algunas de las ideas más importantes que han guiado la investigación.

A estética do celibato como expressão de seus fundamentos
Authors: Eufrásio Thiago De Moliner
Published: October 2021

No pós-Concílio Ecumênico Vaticano II o papa Paulo VI respondeu as objeções acerca do celibato com a encíclica Sacerdotalis Caelibatus em 1967. Para tal apresentou as razões do celibato apoiando-se na cristologia, eclesiologia e escatologia. Tais fundamentos permitem ao candidato ao celibato apreender o sentido último do dom recebido e vivido como expressão da profundidade do amor humano como participação no mistério da encarnação de Jesus Cristo que culmina em sua Paixão, Morte e Ressurreição. Em tal participação, chamado a amizade com o Redentor, o ministro ordenado expressa a estética do celibato em seus movimentos de configuração, disponibilidade e esperança.
LA DISLEXIA COMO MANIFESTACIÓN DE NEURODIVERSIDAD
Authors: Beltrán-Rodríguez Yenny Alejandra , Gutiérrez-Ospina Gabriel
Published: October 2021

La habilidad lectora está representada por una curva de distribución normal en la que el fenotipo denominado disléxico constituye aproximadamente el 17%. Esta distribución y frecuencia hacen de este fenotipo una expresión alternativa de la normalidad lectora en el ser humano. En este trabajo se propone un modelo que mira a la dislexia como una manifestación de neurodiversidad, superando las ideas que la presumen como una neuropatología. En él se sugiere que las variantes disléxicas son alternativas fenotípicas que permiten a los individuos desarrollar habilidades cognitivas novedosas y adaptativas. Para este fin, se analizó el marco conceptual y experimental de 143 artículos científicos obtenidos de las bases de datos ScienceDirect, NCBI y PubMed, seleccionados bajo los términos de búsqueda “dislexia” y “lectura”, relacionados con su neurobiología, diagnóstico, características y neurodiversidad. La inclusión adicional de datos neurofisiológicos y neuroanatómicos, representados por modelos a lo largo del trabajo, permitió ilustrar la diversidad de las organizaciones cerebrales que ratifican la idea de que los “cerebros disléxicos” no representan un rasgo fenotípico inadaptado, sino más bien un arreglo de organizaciones cerebrales que proporcionan posibilidades cognitivas diversas. En consecuencia, se construyó un modelo neurobiológico teórico para lectura y dislexia que procura predecir las múltiples posibilidades de procesamiento de la información para ambos fenotipos. Esta teorización condujo a proponer un nuevo concepto para referirse a las variantes “disléxicas” del fenotipo humano, la holodisnomia, término que aspira a sustituir el término dislexia y que atiende a la capacidad de los individuos que lo exhiben de procesar la información de manera global (holo-), así como desarrollar una estructura de pensamiento que diverge positivamente de la norma (-disnomia).
