Los sistemas de producción hidropónicos son una técnica viable que permite un mejor uso del agua y fertilizantes, actualmente se busca incrementar la funcionalidad de estos sistemas, por medio de la adaptación de sistemas existentes, con la finalidad de hacer más eficiente el manejo, incrementar producción y calidad de los cultivos. El objetivo de este trabajo es evaluar el efecto de un sistema hidropónico en carrete en la producción (SHC) y calidad bioquímica de frutos de tomate, comparado con un sistema hidropónico convencional en sustrato (SSH). Se encontraron diferencias estadísticas entre tratamientos para variables bioquímicas como vitamina C, capacidad antioxidante y proteínas totales, así como en características de interés comercial como solidos solubles totales y acidez titulable; no hubo diferencias para glutatión, compuestos fenólicos, flavonoides, licopeno y beta-caroteno; la producción se incrementó en un 15% en el SHC en comparación con el SSH y las plantas en SHC mostraron menor estrés hídrico en floración y cosecha a diferencia del SSH. El SHC influye en el contenido de biocompuestos en frutos de tomate de interés bioquímico y comercial, así mismo incrementó del rendimiento total por planta, lo cual representa una ventaja productiva y económica, por lo que el SHC es una propuesta importante como sistema de producción.
De Verdún al Ministerio de Guerra. La política militar francesa y la reforma militar de Manuel Azaña
Authors: Roldán Cañizares Enrique 
Published: November 2024

Las reformas militares implementadas por Manuel Azaña fueron uno de los pilares renovadores en los que se sustentó la II República española, la cual identificó las reformas agrarias, religiosas y militares como fundamentales para la transformación que el régimen republicano pretendía aplicar a España. En este sentido, la figura de Manuel Azaña como ministro de Guerra es fundamental, pues fue él quien, a base de decretos, imprimió el giro necesario que necesitaba un ejército que aún no se había recuperado del conflicto en territorio marroquí. Así, este artículo parte del estudio que Manuel Azaña realizó sobre la política militar francesa durante la I Guerra Mundial, analizando si sus aprendizajes sobre el ejército en los frentes de Francia e Italia tuvieron algún tipo de influencia en las medidas tomadas una vez que se convirtió en el ministro de Guerra del Gobierno Provisional republicano.

Published: November 2024

Osteochondromas are benign bony tumours with only 1–4% being located in the spine. Compressive myelopathy as a presentation of vertebral osteochondroma in a child is a rare entity. Our case being 6-year-old female with multiple osteochondroma involving spine presenting as spastic paraplegia is itself rare as males of 2nd decade are mostly affected. Father of the patient also had osteochondroma like lesion over knee showing its autosomal dominant inheritance. Appropriate imaging followed by surgical decompression is key to minimize further complications.

Patient satisfaction can be defined as the degree of congruency between a patient’s expectations of ideal care and his /her perception of the real care (s) he receives. It is a multidimensional aspect and represents a vital key marker for the quality of health care delivery.The cross-sectional study was conducted among the IPD patients in the indoor wards of SGRD Hospital which is a tertiary care hospital. A self-structured questionnaire was used to collect data. Questions regarding twelve potential problems were asked which could have been faced by the respondent during their stay in hospital.A total of 226 respondents were interviewed. 52.2% of the respondents were females and remaining (47.8%) were males. Overall satisfaction of the patients from the IPD services provided by the hospital was found to be 87.2%. Major problems faced by the respondent were difficulty in accessing the hospital (46%) and higher overall cost of treatment than expected (45.6%). Most of the respondents were satisfied with quality of food and water available (97.8%) and quality of linen provided by hospital and sanitary conditions of ward (97.3%).The study suggests that majority of In-patients are highly satisfied with the IPD services provided by the hospital which is highly motivating but every attempt must be made to form new policies and reform existing ones to achieve 100% satisfaction of patients. A number of potential barriers have been discovered in this study. Periodic patient satisfaction survey must be institutionalized in order to continuously improve hospital services. Patient counseling and health education cells could be open where patients and their relatives could solve their queries.
Positional asphyxia: Potpourri of cases
Authors: Kishore Manjari , Singh Jitender Pratap 
Published: November 2024

A legal medicine specialist will likely be able to observe a variety of situations in which positional asphyxia, a deadly condition resulting from the adoption of specific body positions that cause mechanical interference with pulmonary ventilation, can occur (work, car accidents, torture, kidnapping, etc.). In these circumstances the cause of death is typically difficult to determine because the patient typically presents with a distinct anatomo-pathologic appearance.Because of chest compression, positional asphyxia can occasionally be difficult to differentiate from asphyxia. The primary distinction is in how the incident happened: that is, if the specific posture that resulted in asphyxia was acquired voluntarily or was due to an external mechanical action that led to traumatic asphyxia.Three basic criteria are used to diagnose positional asphyxia: the body posture must impede normal gas exchange , moving to a different position must be impossible, and alternative cause of natural or violent death must be ruled out. The authors here present a series of five cases drawn from the professional experience to highlight the primary patho-physiologic and diagnostic causes of positional asphyxia.

Published: November 2024

Background: The purpose of this investigation was to look into and collect data on the variables affecting the intake willingness of goat meat by Algerians. Methods: In the region of El Oued (in southeast Algeria), 240 consumers were selected at random for sampling. The information obtained during the survey was collected using a standardised questionnaire. Result: According to the findings, goat meat ranked third (11.25%) among consumers’ top choices for red meat, behind beef (15%) and sheep (71.25%), but ahead of camel meat (2.5%). Of the previously mentioned meat types, taste was found to be the most desirable trait (53.75%). The majority of survey participants (202 consumers; 84.16%) thought that the meat from goats was suitable for them. On the contrary, all-around quality, level of income and methods used to raise animals have the greatest impact (p less than 0.05) on goat meat consumption willingness. However, there were no appreciable differences (p greater than 0.05) in the intake willingness of this meat based on age, gender, location of residence, level of education, accessibility, or cost. This study offers a thorough understanding of the aspects that influence consumer attitudes regarding goat meat and may be employed in developing strategies for enhancing consumption and boosting acceptance.

Published: November 2024

Introduction: Every month's regular menstrual cycle should ideally span 21-35 days. The menstrual cycle is influenced by several factors, namely stress levels and sleep quality. Menstrual cycle disorders indicate metabolic and endocrine system irregularities. The impact that often occurs due to menstrual cycle disorders is infertility and difficulty identifying the fertile period. The purpose of the study was to determine the relationship between stress levels and sleep quality with the menstrual cycle in seventh-semester nursing students at Universitas Muhammadiyah Lamongan. Methods: This research design uses correlation analytics with a cross-sectional approach using a simple random sampling technique with a sample of 111 respondents. Measured using the Depression Anxiety Stress Scale questionnaire sheet for stress levels and the Pittsburgh Sleep Quality Index questionnaire for sleep quality. After tabulating the data and analyzing it using the Spearmen Rank test. Results: This study showed that almost half of the 43 female students (38.7%) experienced mild stress and more than half of the 60 female students (54.1%) had poor sleep quality. Conclusions: Based on the results of the analysis using the Spearmen rank test, the value of p = 0.000, where p <0.05 means that there is a relationship between stress levels and sleep quality with the menstrual cycle in nursing students in semester VII of Universitas Muhammadiyah Lamongan. Based on this research, it is expected that female students can reduce stress, get enough sleep 7-8 hours, diet, and control weight so that the menstrual cycle returns to normal.
Optimizing Oil Production in Naturally Fractured Carbonate Reservoirs with Gas Coning Under Gas Production Constraint
Authors: Ibragimov Abdulmalik , Ussenova Kamshat , Zhiyenkulov Murat 
Published: November 2024

Abstract
Gas coning is a frequent issue in naturally fractured carbonate reservoirs with a gas cap and an oil rim, leading to decreased oil production and early well abandonment. This paper proposes a production optimization approach for wells experiencing gas breakthrough in such reservoirs to improve ultimate oil recovery. The authors developed a numerical model that incorporates the effects of gas coning and breakthrough on a well productivity in the Karachaganak field. Using this model, authors optimizes production rates to maximize oil recovery while adhering to gas production constraints.
The research is focused to demonstrate that the most effective production strategy for a well is to operate intermittently. Additionally, the frequency of a well's uptime and downtime will progressively decrease over time as the fractured zone of a reservoir is depleted. The suggested production optimization approach can enhance oil recovery in naturally fractured tight carbonate reservoirs while reducing the impact of gas coning and gas breakthrough. The outcomes of this study can guide field development plans and optimize production strategies for comparable tight fractured carbonate reservoirs.
Key countries in the structure of the SouthAmerica production network
Authors: Contreras Martha Gabriela Alatriste , Lugo Igor 
Published: November 2024

Abstract

We study the heterogeneous structure of the production network of 10 South American countries using the input-output data for identifying which of those countries and their economic sectors lead the economic performance of the region. We apply complex network analysis to characterize the structure of the economies and the relation between national production networks and the regional economy. Main results give evidence that the most relevant countries for the regional structure are Brazil, Argentina, and Chile. These countries have different structural properties, but contribute greatly to the structure of the regional economy. The most important sectors of the region are agricultural activities and manufacturing of simple low-transformation products such as food. Finally, results give evidence of competition of countries in similar markets, such as meat, rather than cooperation.

Published: November 2024

Abstract

Background
The COVID-19 pandemic has been spreading rapidly since 2019, leading to devastating consequences worldwide, as well as putting healthcare providers at high risk. This study intends to assess the awareness and preparedness activities among maternal healthcare (MHC) workers and to determine factors that lead to obstetric services’ preparedness in ten Government Hospitals in Selangor, Malaysia.
Methods
A cross-sectional survey was conducted among 409 MHC workers which include doctors, nurses, and midwives in the government hospitals in Selangor, Malaysia between May 2022 till June 2022. Respondents were given validated questionnaires which include socio-demographic background, knowledge, awareness, and attitude as well as the obstetric services’ preparedness activities in managing the COVID-19 pandemic.
Results
Majority of the respondents were nurses/midwives (87.5%), female (98.5%), age 35–45 years old (48.5%), had working experience of more than 5 years (92.7%), had good knowledge and awareness (92.2%) and good obstetric services preparedness (88.3%). However, only about half (54.0%) of them had positive attitude towards COVID-19. When controlling for confounding factors, multivariate analysis showed that working period factor (p < 0.001), knowledge and awareness factor (p < 0.001) and attitude factor (p < 0.001) were significant predictive factors of obstetric services preparedness during the COVID-19 pandemic.
Conclusions
The findings in this study revealed that efforts should be made to further increase the knowledge and awareness of MHC workers on COVID-19 and to improve the positivity of their attitude towards this pandemic so that they can provide better obstetric services especially in the current and future pandemics to come.
Timing of induction of labor with catheter – a prospective randomized study with special reference to setting, parity and obesity
Authors: Rinne Kirsi Marja , Lähde Henna , Kolari Terhi , Polo Päivi 
Published: November 2024

Abstract

Purpose:
Induction of labor (IOL) is typically performed during office hours, possibly leading to delivery during duty time. We aimed to evaluate timing between IOL with catheter and delivery.
Methods:
Altogether, 108 women with planned IOL were included in prospective randomized study. Five different time intervals were evaluated: 1) insertion to expulsion of catheter 2) expulsion of catheter to delivery 3) amniotomy to delivery 4) IOL to delivery and 5) the total admission time by setting (outpatient [OP]/inpatients [IP]), parity (primiparous/multiparous) and body mass index (obese/non-obese).
Results:
For IOL setting, the time in the hospital was 17.5 hours longer in the IP group, with no other differences. All time intervals were longer for primiparous than for multiparous women. The same was true for obese women, compared to non-obese women, except in the insertion–expulsion time.
When IOL was performed during office hours, 57.4% of women delivered between 6pm and 6am, and 42.6% between 6am and 6pm (P=0.124). Furthermore, 66.7% of multiparous and 50.0% of obese women delivered between 6pm and 6am, with no difference between settings.
Conclusions:
The setting of catheter IOL did not compromise delivery times. Instead, parity and marginally obesity showed importance.

Abstract

A biofilm is a complex microbial community, representing the initial stage in biofouling formation. Consequently, it is responsible for significant economic losses in several industrial sectors worldwide. Therefore, there is a constant need for safer and environmentally friendly coatings, particularly those derived from new marine sources such as seaweeds with antifouling properties. Red algae produce metabolites that prevent bacterial attachment and biofilm formation by disrupting microbial membranes, inhibiting quorum sensing, or interfering with extracellular matrix production, among them Laurencia johnstonii. This species has particular ecological or geographical advantages that make it more accessible or abundant for research in the Bay of La Paz, BCS. This study aimed to assess the anti-biofilm potential of the red seaweed Laurencia johnstonii. To identify bioactive compounds, the anti-biofilm activity of the ethanolic extract was evaluated against marine biofilm-forming strains: Bacillus altitudinis, Bacillus pumilus, Bacillus subtilis, and Bacillus cereus. The ethanolic extract of L. jonhstonii exhibited the highest percentage of inhibition. Subsequent chromatographic fractionation led to the isolation and identification of laurinterol, the primary compound responsible for the anti-biofilm activity (>97 %) and antibacterial activity (MIC <3.9 µg/mL). To our knowledge, this is the first report of the activity of laurinterol against biofilm-forming strains.
Effect of the starchy legume source on the in vitro fermentation of the fecal microbiota from normal-weight and obese individuals

Published: November 2024

Abstract

The relationship between the microbiota and the health of human beings has been a topic of growing interest in the last few years. Legumes are a rich source of indigestible carbohydrates, including resistant starch, which are substrates of the microbiota. The aim of this study was to evaluate the effect of the indigestible fraction of legumes on the fecal microbiota of normal-weight and obese donors. Accordingly, a preclinical in vitro fermentation model was developed [1]. Short-chain fatty acid (SCFA) production was measured via gas chromatography. In addition, the fecal microbiota was characterized via 16S rRNA sequence analysis. The results revealed that the ratio of the relative abundance of Firmicutes to Bacteroidetes was lower in obese individuals than in normal-weight individuals. Bacteroides was the predominant genus in the fecal inoculum of the obese group. Total SCFA production was significantly greater in the chickpea group than in the lentil and white bean groups among the samples from the normal-weight group. In contrast, white beans presented the highest production of SCFAs in the samples from the obese group. These results suggest that fermentation products (SCFAs) are determined by the components of the legumes, including resistant starches, and the type of microbiota donor (normal-weight or obese individuals).

Abstract

Background: Chronic obstructive pulmonary disease (COPD), which exhibits high morbidity and mortality rates, is a respiratory illness associated with persistent airflow restriction. This study purposed to examine effects of beach chair position on respiratory mechanics in individuals with COPD hospitalized in intensive care unit (ICU) to assess its effectiveness compared to supine position.
Methods: Forty-six participants with COPD, hospitalized in ICU and supported with invasive or non-invasive mechanical ventilation were included in this prospective study. The subjects were initially placed in the supine position. A few hours later, the patients were shifted to spend at least 16 hours a day in the beach chair position. Mechanical ventilator data was recorded every hour in each position. The principal outcome of this study included comparison of compliance, elastance, peak airway resistance, time constant, resistance airway, pH, PCO2 and PO2 data in supine and beach chair positions.
Results: In comparison to supine positioning, beach chair positioning resulted in significant enhancement in compliance (35.98±17.51 ml/cm H2O vs. 44.69±28.74 ml/cm H2O, p value=0.009) and elastance (29.59±11.87 cm H2O/L vs. 39.86±41.55 cm H2O/L, p value=0.009) whereas peak airway pressure, time constant, resistance airway, pH, Pco2 and Po2 did not significantly differ between supine and beach chair position.
Conclusions: Beach chair positioning improves lung compliance and elastance in individuals with COPD in ICU when compared to supine positioning. This study suggests that beach chair position can be advantageous and favorable in terms of respiratory mechanics for COPD patients.
