Redes formativas: esteio para aprendizagens e reflexões enredadas
Authors: Strieder Roque , Tedesco Anderson Luiz
Published: August 2023

Esta reflexão tem por objetivo compreender a existência de implicações epistemológicas, na simbiose humano/tecnociência, que colocam em xeque a razão e as hierarquias de poder, com acenos para a existência de nichos vitais recheados de profunda interdependência desde o início do processo evolutivo. Trata-se de um estudo, de natureza qualitativa, do tipo bibliográfico, cujo principal resultado significa afirmar que a evolução humana emerge em um útero sumamente complexo, que compartilha natureza, tecnologias e linguagens. É inimaginável dimensionar a complexidade das interações, tanto colaborativas quanto conflitivas, dos ingredientes dessas coevoluções interativas - humano e tecnociências. Tem-se, pois, presente na atualidade contemporânea, uma profunda transformação na dinâmica do aprender, possibilitado pelas redes digitais. Conclui-se que as redes formativas são um efetivo exercício de resistência e de profanação dos mecanismos instrucionais originários de convicções político-pragmáticas que desconhecem ou fingem desconhecer a potencialidade das redes, como redes colaborativas, redes de interdependência e presenças interativas. Redes formativas podem possibilitar outras posições e outras conexões diante da tecnoburocratização do Estado, sedento por diagnósticos quantitativos e produtivistas, realizados por planos e metas obscuras que, gradativamente, ameaçam esvaziar as utopias e as esperanças de futuros abertos e possíveis.

Immobility in the bed of pediatric patients in intensive care units increases the risk of morbidities such as pneumonia, with consequences for autonomic function. Physiotherapy based on physical exercise is part of the rehabilitation process and can modify autonomic function. To compare the effects of two physical therapy protocols, one conventional and the other based on physical exercise, on heart rate variability, length of stay and invasive mechanical ventilation in children with ventilator-associated pneumonia. This is a randomized clinical trial, the volunteers were divided into a control group (submitted to a physiotherapy protocol with only breathing exercises and passive mobilization) and an experimental group (submitted to a physiotherapy protocol based on physical exercise). Patients aged 1 to 8 years, on invasive mechanical ventilation, with pneumonia were included. The rehabilitation protocol took place for 4 consecutive days. The collection of heart rate variability occurred in the pre-protocol period, on the 2nd day, 1 day after the end of the protocol. 25 patients completed the study. There was a reduction in the time of invasive mechanical ventilation in the experimental group (p = 0.01). There was an improvement in the heart rate variability of the experimental group in all indices (p < 0.01). The post-protocol analysis of the groups showed significant values in all variables (p < 0.05). Exercise-based physical therapy protocol improved autonomic heart rate modulation and reduced IMV time in children with ventilator-associated pneumonia.

Published: August 2023

The methodology of experimental research of long cylindrical shells to determine their stress-strain state, carrying capacity and crack resistance is proposed. To implement the task, the authors have developed a special stand. Eight cylindrical shell models were made for testing - four of reinforced concrete and four of fiber concrete. Fibro-concrete specimens-shells had additional dispersed reinforcement by steel fiber with bent ends in an amount of 1% by volume of concrete. All specimens-shells had a constant length and cross-sectional radius, and varied the thickness of the shell and the size of the cross-sectional section of the board elements. The paper presents the results of tests of reinforced concrete cylindrical shell, which showed that the carrying capacity of the shell was 96.4 kN, and the first crack formed with a load of 42.9 kN, which is 44.5 % of the carrying capacity. Up to the moment of bearing capacity loss, 8 cracks with the same initial opening width of 0.05 mm and maximum final opening width of 0.8 mm had formed in the shell. Computer modeling of the shell and calculations with ANSYS 17.1 licensed software were performed. The bearing capacity determined in ANSYS was 93.0 kN, which is 3.6 % less than in the experiment. The test methodology and the developed stand are universal and will be used for further research.

Published: August 2023

The article substantiates the method of identifying the mechanical characteristics of concrete of reinforced concrete beams based on the results of fire tests. The idea of the work is to improve the calculation approach to assessing the fire resistance of reinforced concrete beams by clarifying the mechanical characteristics of concrete during its heating under the conditions of exposure to the standard fire temperature regime. The proposed method of identifying the mechanical characteristics of concrete is based on the reproduction of temperature distributions in the cross-sections of reinforced concrete beams based on the results of point temperature measurements during fire tests and the application of equilibrium equations compiled using the deformation mathematical model of the stress-strain state. As a result of the obtained experimental data, the temperature distributions were reproduced using the proposed interpolation method. According to the obtained temperature distributions and the proposed mathematical apparatus, the coefficient of reduction in the concrete strength of reinforced concrete beams during fire tests was identified, the maximum deflection of two sample reinforced concrete beams was determined, and using a deformation model based on the use of equilibrium systems of internal layers in the cross section of reinforced concrete beams, the coefficient of reduction of strength of concrete under the condition of exposure to the standard fire temperature regime was specified.. The presented curves of the value of the coefficient of reduction of concrete strength according to the proposed method and according to the recommendations of Eurocode 2 indicate the presence of a deviation between these indicators. Therefore, the refined dependence of the coefficient of reduction of concrete strength for reinforced concrete crossbars will allow to significantly increase the accuracy of the calculation method of fire resistance assessment for structural elements of this type.

Authors: Lee Eunho , Kim Ha Jin , Hwang Jusam , Park Minseon
Published: August 2023

Background: Diet and physical activity are key factors related to depressive mood. Previous studies have demonstrated the effects of diet and physical activity on depression. However, the effect of energy intake-expenditure balance (EIEB) on mental health has not been fully evaluated. This study aimed to analyze the association between EIEB and depression.Methods: A total of 13,460 participants (5,660 men and 7,800 women) aged ≥19 years were obtained from the 2014, 2016, and 2018 Korea National Health and Nutrition Examination Survey (KNHANES). EIEB was defined as the difference between the daily energy intake and energy expenditure. Energy intake was calculated and provided by the KNHANES using a 24-hour recall survey. Energy expenditure was estimated as the sum of basal metabolic rate and physical activity. Logistic regression analyses were used to investigate the association between sex-specific quartile groups (Q1–Q4) of EIEB and depression after adjusting for socioeconomic status, body mass index, lifestyle factors, and underlying diseases.Results: Women in Q3 of EIEB (211–669 kcal) had a significantly lower risk of depression (odd ratio [OR], 0.78; 95% confidence interval [CI], 0.67–0.92) than those in Q1 of EIEB (<-167 kcal). The adjusted ORs of depression were 0.87 (95% CI, 0.75–1.02) in Q2 and 0.86 (95% CI, 0.74–1.01) in Q4, with P for trend=0.030. There were no significant associations between the EIEB quartile groups and depression in men after adjusting for potential confounders (P for trend=0.564).Conclusion: Our results suggested that the EIEB is negatively associated with depression in Korean women.

Published: August 2023

Background:

The high prevalence of cervical cancer in developing countries, despite its preventive nature, makes the disease a principal matter of concern for scientific studies. Providing global availability of primary and secondary preventive methods based on the high-risk human papillomavirus (HPV), which is the well-known pathogenesis in most malignant cervical lesions, has become the World Health Organization's (WHO's) critical target for 2030. Considering the demographic diversity and manufacturing of the internal vaccine in Iran, there is need for more study on the cost-effectiveness of these strategies.

Materials and Methods:

This study intends to assess female HPV prevalence at the time in Iran provinces, especially in the capital province, Khorasan Razavi, in the north to establish a scientific rationale for conducting further studies on arguments for and against national HPV prevention strategies in line with the WHO. In this population-based study, the HPV prevalence was evaluated in 900 cervical samples accumulated between 2012 and 2015. The data were later compared with recently published data in the same province, in the north of Iran.

Result:

Based on the results of our cross-sectional study, the estimated prevalence of HPV infection in the northern female population was 4.1% in 2015 and significantly increased to 35% in 2021.

Conclusion:

The hypothesis of the impact of behavioral and cultural changes in addition to population aging on general health indicates the need for national health promotion strategies. Additionally, it emphasizes the critical significance of conducting further investigational studies to obtain the actual and updated prevalence of HPV in Iran.

Authors: Shetabi Hamidreza , Hashemi Seyed Jalal , Ghaleshahi Somaye
Published: August 2023

Background:

The present study was performed to compare the effectiveness of propofol–remifentanil and propofol–hydralazine in inducing controlled hypotension in patients undergoing the dacryocystorhinostomy (DCR) surgery and reducing their bleeding volume during surgery.

Materials and Methods:

The present double-blind, randomized clinical trial was performed on 70 patients who were candidates for DCR surgery and divided into two groups. In both the groups, general anesthesia protocol was performed. Moreover, in the first group, a syringe containing 2 mg of remifentanil in 20 ml of distilled water (0.1 mg/ml) was infused at the rate of 0.15 μg/kg/min (P + R group). In the second group, a syringe containing 20 mg of hydralazine in 20 ml of distilled water (1 mg/ml) was infused at the rate of 0.5–10 mg/h (P + H group).

Results:

The hemodynamic parameters were not significantly different between the two groups in the studied times (P > 0.05). In contrast, the bleeding volume in the P + R group with the mean of 61.29 ± 50.06 ml was significantly lower than that of the P + H group with the mean of 152.31 ± 90.81 ml (P < 0.001). Moreover, the mean score of surgeon's satisfaction level in the P + R group was higher than that of the P + H group (5.91 ± 0.28 vs. 4.29 ± 0.65; P < 0.001).

Conclusion:

According to the results of this study, there was no significant difference between the P + H and P + R groups in terms of fluctuations in the hemodynamic parameters and the occurrence of complications. However, a reduction in the bleeding volume and a higher satisfaction level of the surgeon were observed in the P + R group compared with the P + H group.

Published: August 2023

Juvenile Rheumatoid Arthritis(JRA) is defined as a heterogeneous group of chronic inflammatory arthritis that begins at childhood usually below age of 16 years. The severity of the damaged joints increases as the kid gets older, and the possibility that the condition will become dormant also decreases. The treatment program for an Juvenile Rheumatoid Arthritis child has to be individualized and likewise requires a team approach. Physiotherapy management for such an individual will provide symptomatic relief and will also prevent long- term complications of the same. Hence the purpose of this article is to review the literature on the role of Physiotherapy in Juvenile Rheumatoid Arthritis. We performed a narrative review on the role of physiotherapy in Juvenile Rheumatoid Arthritis and discuss the evidence-based studies. For the purpose of the review, an electronic search for relevant articles using PUBMED, MEDLINE, Pedro, Research Gate, Google Scholar and CINHAL databases up to September 2021 was done wherein MeSH search terms and free words were used. In addition to the electronic search, articles were searched manually for relevant studies. Articles were selected based on authors expertise, self- knowledge and reflective practice. Articles published on an online electronic database were included. We included studies published the studies which included physiotherapy as a choice of treatment. The current study included 11 articles that fulfilled the inclusion criteria suggesting that physiotherapy does a have major role in treating the individuals with Juvenile Rheumatoid Arthritis. The above reviewed studies provided evidence that physiotherapy as a mode of treatment is definitely effective in Juvenile Rheumatoid Arthritis.

Authors: Dalvi Shivanee Kishor , Shinde Sandeep Babasaheb
Published: August 2023

Ankylosing spondylitis (AS) is a chronic, inflammatory, and debilitating condition of the spine that causes pain, decreased mobility, and deformity. AS primarily affects the axial skeletal system, causing pain and stiffness in the spine, which can lead to functional impairment, disability, and a poor quality of life. AS assessment formulates an outcome measure to check the disease process and impairment in individuals, and to identify the rapid progressive ones. It also measures the effectiveness of therapies and treatment. The purpose of this review was to find the current status of the functional tools used in the assessment of AS. A systematic review was done to study the functional assessment tools in patients with AS. Articles were selected based on the relevant topics and went through the selection process. The inclusion criteria of the review were as follows: (1) functional assessment, (2) sensitivity and specificity, (3) reliability, and (4) validity. This study included 11 articles that fulfilled the inclusion criteria and suggested that functional assessment tools are important in AS. Few articles suggest that certain tools are effective in the assessment of domains like pain and physical function, whereas few articles give a good measure of pre- and post-physical therapy and pharmacological intervention. The studies used for the review consisted of scales or questionnaires, which were either qualitative or quantitative type. The reviewed studies provided evidence that it was beneficial for assessing the function. There were a lack of data available in which one assessment tool measured all the parameters of AS. In recent advances, video-based motion capture system has turned out to be an effective modern functional assessment tool in AS.
Correlation Between Prolonged Nasogastric Feeding and Temporomandibular Joint Dysfunction
Authors: Shinde Sandeep B. , Ghadage Pradnya , Ambali Manoj P.
Published: August 2023

Background:

Nutrition is administered via enteral feeding in the form of fluid supplements to overcome malnutrition in hospitalized patients, or enteral tubes are intubated into the stomach and small bowel if the patient is unable to feed orally. The most common procedure performed by doctors across all medical specialties is nasogastric intubation. However, it has its own complications such as nasopharyngeal pain, aspiration, and trauma while insertion of the tube, but the impact of prolonged nasogastric tube feeding on temporomandibular joint (TMJ) is unknown. There is paucity of literature focusing on the TMJ; therefore, this study focuses on the correlation of prolonged nasogastric tube feeding and temporomandibular joint dysfunction.

Materials and Methods:

This was an observational study conducted among 59 participants. Patients undergoing nasogastric feeding for more than a week and having pain during mouth opening and left right lateral excursion were included in the study. Subjects with previous trauma to TMJ were excluded from study. Patients who were unconscious or uncooperative, had previous trauma to TMJ, and had facial surgery were excluded from the study.

Result:

Multivariate analysis revealed that there was no significant limitation of range of motions (ROMs; mouth opening [P = 0.232, t = 8.800], protrusion [P = 0.315, t = 17.130], right lateral excursion [P = 0.511, t = 16.768], and left lateral excursion [P = 0.5108, t = 18.143]) when compared to the ROMs at the time of insertion of nasogastric tube and 5–14 days after the removal of nasogastric tube. Also, there was significant TMJ pain.

Conclusion:

The study concludes that there was a significant correlation between duration of intubation and pain in masticatory muscles such as the temporalis and masseter, and medial and lateral pterygoid muscles and weak correlation between prolonged nasogastric intubation and TMJ movements.
Demographic dynamics and the changing faces of nutrition literacy in India: A tryst with the transition among communities over two decades
Authors: Bhatia Vikas , Parida Swayam P , Panda Meely
Published: August 2023

Abstract

Aims and Objective:

The development of a nation depends on well-nourished individuals. A country’s economic independence also depends on adequate food supply for all sections of its population and the proper selection of the right kinds of food, called nutritional literacy. This review will show the transition of dietary selection and practices across India over the last two decades and its impact on health.

Materials and Methods:

We conducted a literature search to review the evidence of the last two decades. The literature search was done using the PubMed search engine and the MeSH words “Nutrition Literacy, Dietary Practices, Diet Transition, Nutrition transition, India and Food pattern.” Evidence from the last two decades was collectively reviewed, and observations on the transition in nutrition literacy were summated.

Results:

The literature search revealed 18 articles, out of which 13 articles were included in this review based on inclusion–exclusion criteria. Nine were review articles, and five were cross-sectional studies. The studies done over the last two decades on nutrition culture revealed that most of the studies related to transition have been done during the second decade of the twenty-first century. Most have found that the shift has been happening more among the urban poor and rural rich people. Indian diets have diversified and shifted away from cereals towards processed food.

Conclusion:

It was found that there is a shift in feeding preferences in diet-deprived sections in India. The findings are similar in rural and urban areas where the poor fall prey to the food fads, make poor nutrition choices, and gradually develop chronic ailments. Such a transition over the years clearly shows that a malnourished child, having faulty feeding practices, becomes prey to the triple burden of hidden hunger, lack of nutrition, and repercussions of chronic non-communicable diseases, including dental ailments.
Interactive effect of salivary protein carbonyl, total glutathione, pH, and flow rate on root caries severity: A case–control study
Authors: Yas Baydaa Ahmed
Published: August 2023

Abstract

Aims and Objectives:

Oxidant and antioxidant components in saliva play an essential role in caries development. The purpose of the current study was to disclose the interactive effect of salivary protein carbonyl (PC), total glutathione (GSH), pH, and flow rate on root caries severity.

Materials and Methods:

The control and study groups consisted of 90 older adults of both genders classified into six groups: normal salivary flow rate with no root caries (control), normal salivary flow rate with incipient root caries, normal salivary flow rate with shallow root caries, hyposalivation with no root caries, hyposalivation with incipient root caries, and hyposalivation with shallow root caries. Each group consisted of 15 older adults. The study participants were selected from those patients who attended the teaching hospital at the College of the Dentistry/University of Baghdad and fit the study’s criteria. Unstimulated saliva was collected. Both salivary pH and flow rate were determined immediately. After that, saliva was subjected to biochemical analysis to determine PC and total GSH levels colorimetrically. Root surface caries was diagnosed clinically using the Root Caries Index. Data were statistically analyzed using descriptive statistics, two-way univariate analysis of variance, two-way multivariate analysis of variance, and Pearson’s correlation coefficient (α = 5%).

Results:

Salivary total glutathione revealed a significant interactive effect with salivary flow rate and root decay severity. Levels of salivary total GSH were significantly higher in subjects with shallow root caries than those with incipient root caries; no root caries levels of salivary PC were significantly high in the hyposalivation group, but no correlation with caries severity was found. High root caries severity was found to be associated with reduced salivary pH and flow rate.

Conclusion:

A significant interactive effect was recorded for salivary flow rate, pH, and total GSH on root caries severity except for salivary PC.

Published: August 2023

Abstract

Aims and Objectives:

The primary objectives of this study were to compare salivary oxidative stress (OS) biomarker levels in patients with type 1 diabetes mellitus (T1DM) and without T1DM (non-T1DM) and evaluate the relationships between diabetes, periodontal status, and OS biomarker levels.

Materials and Methods:

Twenty patients with T1DM and 20 age-matched patients without T1DM were enrolled. All participants were 15–23 years of age and had permanent dentition. Unstimulated whole saliva was collected in a sterile test tube before examination of clinical periodontal parameters, including bleeding on probing (BOP). Salivary levels of OS biomarkers—malondialdehyde, protein carbonyl, total oxidant status (TOS), and total antioxidant capacity—were determined using oxidative and antioxidative assays followed by spectrophotometric measurement at 375–532 nm. The relationships between diabetes, periodontal status, and OS biomarkers were analyzed using multiple linear regression.

Results:

TOS was significantly lower in the T1DM group compared with the non-T1DM group (5.06 ± 0.39 vs. 6.44 ± 0.51 µmol H2O2 Eq/l, P = 0.035). After adjusting for confounding factors (age, gender, BMI, clinical periodontal parameters, BOP, or diabetes status accordingly), the multiple linear regression showed that T1DM was significantly associated with a reduction of TOS level (P = 0.008). The BOP > 30% group showed a significant correlation with increased TOS levels compared with the BOP ≤ 30% group (P = 0.002). No relationship was found between OS biomarkers and HbA1c levels.

Conclusion:

Salivary TOS levels were related to both diabetes status and the extent of gingival inflammation. Further studies to elucidate the role of OS in relation of periodontal disease and T1DM are required.

Abstract

Aims and Objectives:

To perform a bibliometric study to identify and evaluate articles associated with “orthodontic wires” indexed in six databases (PubMed, Embase, Cochrane, Scopus, Lilacs, and Google Scholar) from 2010 to 2022.

Materials and Methods:

The search strategy in PubMed combined different medical subject heading terms with free-text words and was adjusted for each selected database. The retrieved documents were original English articles containing the keywords used in the search strategies related to orthodontic wires. Collected data consisted of journal name, nationality, field, JIF-2 and JIF-5, SJR, CiteScore, Q and H-index, and categorization of the study.

Results:

In total, 417 articles were retrieved from the initial search. After the exclusion criteria, 257 articles remained. The most common theme was mechanical properties, with basic studies as the main categorization.

Conclusions:

This bibliometric survey provides an overview of orthodontic wires publications that might help orthodontists to understand the tendency of the studies on this subject. The retrieved papers were published in 100 journals, including 15 orthodontic journals, mainly in the first and second quartiles. Europe and America were the continents with the highest number of papers. The United States was the country with the highest number of journals on the topic. AJODO presented the highest h-index among the retrieved orthodontic journals. Brazil represented the principal institutions of origin of the listed articles. There was a tendency to increase the number of publications on orthodontic wires over the years. These findings indicate that research on orthodontic wires is still contemporary and relevant.

Authors: Tran Thi Xuan Mai , Kim Soyeoun , Song Huiyeon , Park Boyoung
Published: August 2023

OBJECTIVES: This study investigated the risk of developing and dying from all types of cancer, as well as cancer-specific mortality, in women diagnosed with prediabetes and diabetes.METHODS: We included women aged ≥40 years who underwent cancer screening from 2009 to 2014 with follow-up until 2020. Diabetes status was determined based on fasting plasma glucose levels, self-reported history of diabetes, and the use of antidiabetic medication. We quantified the risk of cancer and mortality in the prediabetes and diabetes groups, relative to the normoglycemia group, by calculating adjusted hazard ratios (aHRs).RESULTS: The study included 8,309,393 participants with a mean age of 52.7±9.7 years. Among these participants, 522,894 cases of cancer and 193,283 deaths were detected. An increased risk of cancer was observed in both the prediabetes group (aHR, 1.03; 95% confidence interval [CI], 1.02 to 1.04) and the diabetes group (aHR, 1.13; 95% CI, 1.12 to 1.14). The highest risk was identified in those with diabetes who developed liver (aHR, 1.72; 95% CI, 1.66 to 1.79), pancreatic (aHR, 1.68; 95% CI, 1.60 to 1.76), and gallbladder cancer (aHR, 1.43; 95% CI, 1.36 to 1.51). Women with prediabetes and diabetes exhibited a 1.07-fold (95% CI, 1.05 to 1.08) and 1.38-fold (95% CI, 1.36 to 1.41) increased risk of death from cancer, respectively.CONCLUSIONS: Both prediabetes and diabetes were associated with an elevated risk of cancer, as well as an increased risk of death from cancer, in middle-aged Korean women. However, the degree of risk varied depending on the specific site of the cancer.

The recent worldwide pandemic of Covid-19 induced major issues through herbal medicine. This study was conducted between August  2020 and March 2021, with the aim to evaluating the knowledge of the population on the usefulness of herbal medicine in the treatment  of Flu, cough, cold and Covid-19 and identifying therapeutic recipes used at Mbanga and Yaounde cities. The results showed that 88.46%  and 67.69% of population respectively at Mbanga and Yaoundé agreed to the use of medicinal plants. Of the 130 people interviewed per  city, the most affected were between 40-50 years old for Mbanga (33.07%) and 30-40 years old for Yaounde (43.84%). A total of 16  therapeutic recipes, mostly prepared by infusion or fermentation, were identified. These recipes use 11 plant species which belong to 9  genera and 9 botanical families. Herbal medicine seems to be a major solution in the treatment of upper respiratory diseases in these  cities, although some fear the risks associated with this practice, due to the dosage as dosing is not mastered.

A prospective study was conducted on feeds for local poultry in Burkina Faso. The objective of this study was to contribute to the  improvement of the nutritional and economic quality of feeds for local poultry. Design of experimental (DOE) method was used to  formulate ten feeds with mainly local raw materials and an evaluation of their nutritional and economic value has been carried out.  Classical analytical methods were used to determine the macro elements. Chromatography and flame spectrometry were used to  determine amino acids and minerals respectively. The results showed mass proportions (g/100 g DM) between 18.32±0.06 and 20.46±0.00  for proteins, 4.86±0.10 and 5.70±0.03 for lipids, 36.81±0.07 and 40.36±0.04 for total carbohydrates, between 10.28±0.09 and  12.34±0.12 for ash, between 7.03±0.09 and 7.79±0.00 for cellulose, 1.67±0.74 and 3.86±0.06 for calcium, 1.16±0.07 and 2.10±0.04 for  phosphorus. Methionine contents ranged from 0.36±0.04 to 0.47±0.02, lysine from 0.78±0.07 to 0.94±0.00, and threonine from 0.68±0.02  to 0.83±0.03. The rations cost varied from 203.40 to 238.98 FCFA/kg with an average value of 213.77 FCFA/kg. The results obtained  constitute new information in the breeding of local chicken in Burkina Faso. They will allow poultry farmers to make their activity more  profitable.

Dans les exploitatations agricoles productrices de maïs à l’Ouest du Burkina Faso, les pratiques paysannes de fertilisation ne contribuent  pas à une productivité durable des sols et des cultures. L’étude conduite en 2020 avait pour objectif, de determiner les effets de ces  pratiques de fertilisation et des rotations culturales sur les paramètres chimiques des sols et les rendements du maïs. Elle a été réalisée à  travers le suivi de 50 champs paysans. Sept régimes de fertilisation du maïs ont été identifiés et cinq régimes étaient pratiqués dans les  champs de brousses. L’Analyse des Correspondances Multiples a montré que les rendements étaient liés à ces régimes. Le rapport C/N  du sol dans les champs de case et champs de village ainsi que le rendement paille des champs de brousse ont augmenté avec les  rotations culturales. Les relations entre les régimes de fertilisation, les rotations culturales, les caractéristiques chimiques des sols et le  rendement du maïs, etaient fonction du type de champ. Les pratiques d’une gestion durable de la fertilité des sols et le respect des doses  recommandées de fumures organiques (5 t/ha tous les deux ans) et minérales (150 à 200 kg/ha de NPK et 100 kg/ha d’urée) sont  à promouvoir 

 

English title: Farmers’ maize fertilization practices and crop rotations in western Burkina Faso farming systems: what effects on soil  chemical properties and yields?

In the western Burkina Faso cropping zone , farmers fertilization practices are inaproriate to sustainablesoil and crop productivity. The study, conducted in 2020, aimed to determine fertilization practices and crop  rotations effects on soil chemical parameters and maize  yields. It was carried out through the monitoring of 50 peasant fields. Seven  maize fertilization regimes were identified and five regimes  were practiced in bush fields. Results from Multiple Correspondence Analysis showed that yields were related to these regimes. C/N ratio  in the home fields and village fields as well as the straw yield in bush fields were increased under crop rotations. The relationships  between fertilization regimes, crop rotations, soil chemical characteristics and maize yield were a function of field type. The practices of  sustainable management of soil fertility and compliance with the recommended rates of organic manure (5 t/ha every two years) and  mineral fertilizer (150 to 200 kg/ha of NPK and 100 kg/ha of urea) should be promoted.

Electric power quality problems include line losses, voltage drops, and the amount of inductive reactive power consumed at load so the power factor is low. Power factor improvement in Politeknik Penerbangan Surabaya electrical system to 0,99 is expected to improve electric power quality by installing a setcapacitorsitor called Capacitor Banks that supply capacitive reactive power. Another benefit is that reduces the load on transformer Poltekbang Surabaya which is now approaching full load. To be able to repair the electric power supply is necessary to measure and calculate the inductive reactive power which can be compensated with witcapacitiveie reactive power by Capacitor Bank. After calculating the capacitor bank value, the location of the capacitor bank installation is then determined so that power improvements can be carried out effectively, The result shows that the compensation needed to improve the power factor on Poltekbang Surabaya is 300 kVAR divided into 5steps, each step requires a 50 kVAR capacitor

CRYSTALS-Dilithium has been selected by the NIST as the new standard for post-quantum digital signatures. In this work, we revisit the side-channel countermeasures of Dilithium in three directions. First, we improve its sensitivity analysis by classifying intermediate computations according to their physical security requirements. Second, we provide improved gadgets dedicated to Dilithium, taking advantage of recent advances in masking conversion algorithms. Third, we combine these contributions and report performance for side-channel protected Dilithium implementations. Our benchmarking results additionally put forward that the randomized version of Dilithium can lead to significantly more efficient implementations (than its deterministic version) when side-channel attacks are a concern.
Katalonien und Deutschland: ein Überblick über die kulturgeschichtlichen Wechselbeziehungen
Authors: Briesemeister Dietrich
Published: August 2023

In the cultural relationships between Germany and Spain, the contribution of the Catalan countries is usually covered for by the culture of the Castilian Spanish language which has long been predominant. And yet over the course of five hundred years there has been a partly very active exchange between the old Catalan cultural area and the German-speaking countries in Central Europe. The works of Ramon Llull, Arnau de Vilanova, Joan Lluís Vives, Anselm Turmeda and Ramon Sibiuda have been widely circulated here. The very useful Vocabulary for learning Catalan German and the German Catalan (1502) is a valuable testimony to the first linguistic relations. From the first years of the 19th century, scientific work on Catalan subjects – history, language and literature, cultural anthropology – took a considerable turn. Lullian studies have been the subject of special dedication and continue to be so to this day. It was not until the end of the last century that interest in modern Catalan literature grew (translations by Jacint Verdaguer or Víctor Balaguer). In German Romantic literature, Montserrat plays a surprising role. From the Renaissance onwards, German literature and music (Richard Wagner) garner a great deal of attraction. Since the last years of the twentieth century, modern Catalan literature has increasingly been considered. The Catalan Weeks in Berlin and Karlsruhe have, in recent years, managed to draw public attention to Catalan culture.
Die Orthographie-Debatte im Diario de Barcelona 1796 und ihr soziolinguistisches Umfeld
Authors: Kailuweit Rolf
Published: August 2023

Catalan linguistic historiography applies the categories of "linguistic conflict", which are quite useful for describing the current situation, also to the pre-Renaissance period. This period, still aristocratic, nevertheless shows a very different sociolinguistic structure, generally characterized by the absence of awareness of a linguistic conflict. The controversy over Catalan spelling that took place in the Diario de Barcelona in 1796 therefore seems more like the creation of a literary genre with the aim of distracting the public than a serious discussion. However, there are two linguistic attitudes that are typical of the time, as evidenced by the comparison with other documents: on the one hand “happy bilingualism” which, despite using the Castilian language, expresses esteem for Catalan and its philological tradition and, by doing so, rejects the process of Catalan being substituted by Spanish; and, on the other hand, a "frustrated" position that recognizes this process without having the means (yet) for a defence of Catalan. For both positions, Spanish is the point of reference and essential as a language of culture. At the end of the 18th century, a specific Catalan identity shows up, which continues to use Castilian as means of expression. Catalan, however, is still being written, a very important factor for the Renaixença. Now, under different sociolinguistic conditions, language has truly become the subject of public conflict.
La narrativa catalana a Mallorca a partir dels anys setanta
Authors: Janer Maria de la Pau
Published: August 2023

In the form of a general, comparative overview, the most important works, authors, subject areas and trends in the novels and short stories written by Majorcans in Catalan since 1970 are named. A distinction is made here between the so-called “Generation of the 70s”, who have now been literary active for two decades, and the new generation of young authors of the 1980s. Both groups are described in their essential characteristics. While the older generation of writers mostly developed their own Catalan style autodidactically, the younger generation has mostly completed a modern philology course and learned the written use of Catalan from an early age.
Der Torsimany und die scholastische Grammatik
Authors: Schlieben-Lange Brigitte
Published: August 2023

Lluís d'Averçó's Torsimany is usually linked to the tradition of the Leys’s d‘Amors, that is, to the compendiums of troubadour language and poetry. It is interesting to ask whether Occitan and Catalan grammarians knew the scholastic linguistic theory, which was more interested in the universal characteristics of the language, or whether they were completely separated from it by being interested in the mere description of the language and the poetics. A specific detail allows us to refine the possible affiliations of Torsimany: the treatment of declension cases and the meaning of the problematic term "(h)abitut" that Casas Homs, the editor of Torsimany, identifies too directly with "article". It can be shown that Lluís d'Averçó actually understands this term in a broader way: as the designation of all kinds of case relations (including prepositions and adverbs if they have the function of designating cases). This leads us to the assumption that d'Averçó had direct contact with the Latin works of the Modistae.
Usos lingüístics de l'alumnat d'origen estranger a l'educació primària de Catalunya

Summary: The recovery and preservation of the Catalan language initiated during the 1970’s has been a long process that has been backed by the positive attitudes of the whole population towards this language. However, in the last 10 years, the demographic composition of Catalonia has changed substantially. The article presents two studies about the linguistic uses of migrant students in primary education. The first study analyses the linguistic uses of 625 12-year-old foreign students in 53 different schools, whereas the second study is an ethnographic research about the linguistic uses of foreign students carried out in a school where 90% of the students are migrants. The results show that, little by little and no matter if Catalan is the language of instruction or not, Spanish is the socially dominant language usually used by most foreign students. The only variables which modify this tendency are the presence of a high percentage of Catalan-speaking students in the classrooms and the use of Catalan in the students’ social environment.

La llengua catalana en terres valencianes al segle XVIII. Resistència, estudi i conreu
Authors: Martí Mestre Joaquim
Published: August 2023

Summary: The years following the Decree of Nueva Planta were marked by Bourbon centralism and by the pressure of the Spanish language. However, the practise, study and writing of the Catalan language showed persistence throughout the Valencian land. Common people remained faithful to their language to a large extent, as proven by popular literature and historical evidence. People did not trust in the Castilian authorities and considered the Castilian and Valencian bourgeois that had begun to adopt the Spanish language foreigners. At the same time, the general public preserved a sense of social consciousness towards the Catalan language throughout the century, which then turned into an element of group identity, therefore assuring its survival. Many writers also maintained this sense of consciousness towards the Catalan language and the desire to improve its situation, not only regarding internal aspects (orthographic, grammatical, lexical) but also social ones (normative use, education, diffusion).

El còmic a Mallorca durant els anys vuitanta. Un mitjà de renovació cultural
Authors: Lladó Pol Francisca
Published: August 2023

Summary: The comic of the 1980s in Mallorca presents some peculiarities which are a consequence of the period following Franco's death. The first, rather primitive examples of this new type of comic appeared around 1976, mostly in the form of socalled fanzines, which were directly related to the renewal of the visual arts, not only in the media, but especially those of the avantgarde. As early as 1983, the first magazines appeared that were distributed by commercial infrastructure and that aimed to renew conservative Majorcan society. This development eventually caused the comic to acquire characteristics, which gradually led this form of art towards postmodernism. The present article analyzes the role of comics as a medium of cultural renewal, arguing that the comics produced in the island be understood as an element of transcendence towards new forms of creation.
