Authors: Mohammed Safaa , Hasan Afrah
Published: June 2024

Construction projects in Iraq suffer from many complex problems. Therefore, the aim of this study is to identify the most critical factors affecting the performance of Iraqi construction projects, delving into their identification, analysis, and understanding. A comprehensive list of 32 influential factors was compiled through site surveys, interviews with engineers and experts, and a review of previous research. These factors were categorized into eight groups: planning and management, design and engineering, procurement and supply chain, workforce and labor, technology and innovation, environmental and regulatory aspects, site conditions and infrastructure, and external factors. One hundred and ten questionnaires were distributed to project stakeholders, including owners, consultants, and contractors. The results found that the five most important factors affecting performance ranked using the relative importance Index are poor planning, failure to allocate resources properly, unavailability of skilled labor, poor labor productivity, and volatile economic conditions. Based on these results, for solutions to be effective, they must be adapted to the local environment. Project participants must be interested in planning as it is essential to address the same. The skills of project workers must be developed through training programs. Communication with project stakeholders must be coordinated to contribute to the decision-making process.
PointNet-based modeling of systematic distance deviations for improved TLS accuracy
Authors: Hartmann Jan , Ernst Dominik , Neumann Ingo , Alkhatib Hamza
Published: June 2024

Terrestrial laser scanners (TLSs) have become indispensable for acquiring highly detailed and accurate 3D representations of the physical world. However, the acquired data is subject to systematic deviations in distance measurements due to external influences, such as distance and incidence angle. This research introduces a calibration approach by applying a deep learning model based on PointNet to predict and correct these systematic distance deviations, incorporating not only the XYZ coordinates but also additional features like intensity, incidence angle, and distances within a local neighbourhood radius of 5 cm. By predicting and subsequently correcting systematic distance deviations, the quality of TLS point clouds can be improved. Hence, our model is designed to complement and build upon the foundation of prior internal TLS calibration. A data set collected under controlled environmental conditions, containing various objects of different materials, served as the basis for training and validation the PointNet based model. In addition our analysis showcase the model’s capability to accurately model systematic distance deviations, outperforming existing methods like gradient boosting trees by capturing the spatial relationships and dependencies within the data more effectively. By defining test data sets, excluded from the training process, we underscore the ongoing effectiveness of our model’s distance measurement calibration, showcasing its ability to improve the accuracy of the TLS point cloud.

Objective

This study aimed to evaluate the efficacy and safety of solid organ transplantation recipients inoculated with an inactivated COVID-19 vaccine.

Methods

We retrospectively analyzed the antibody levels and related adverse events of non-transplantation subjects and solid organ transplant recipients, both pre-transplantation (individuals awaiting organ transplantation) and post-transplantation (individuals who have undergone organ transplantation), who received inactivated COVID-19 vaccines from February 2021 to July 2022.

Results

The study included 38 pre-transplantation vaccination group, 129 post-transplantation vaccination group, and 246 non-transplantation group. The antibody titer was assessed monthly within the period of 1–12 months after the last injection. The antibody-positive rate among the three groups were 36.84, 20.30, 61.17% (P < 0.05). The antibody-positive rates among three groups with one, two doses vaccine were not significantly different (P > 0.05), but were significantly different after three doses (P < 0.05). The antibody titers among three groups were significantly different after two doses (P < 0.05). Adverse reactions occurred in six transplant recipients, which were relieved after treatment, and not in the non-transplantation subjects.

Conclusion

Inactivated COVID-19 vaccine is safe and effective for solid organ transplantation recipients, at least two doses of which should be completed before organ transplant surgery.

Archaeometric Study of Iron Age Pottery Production in Central Sicily: A Case of Technological Conservatism
Authors: Tanasi Davide , Levi Sara Tiziana , Caso Gianpiero , Tykot Robert H. , Greco Enrico
Published: June 2024

This study presents an in-depth archaeometric investigation of Iron Age ceramic assemblage dating from 950 to 750 BCE from the sanctuary at Polizzello Mountain, Sicily. The site, a key sanctuary utilized by indigenous communities for ritual activities, is examined for its strategic location, structural developments, pottery assemblages, and evidence of communal activities. The study employs petrographic analysis on thin sections, integrated with other analytical methods, to explore the technology behind pottery production. It investigates whether such production reflects a common technological knowledge shared by a broader community or if they represent a blend of different manufacturing traditions. The findings highlight that the pottery from Polizzello Mountain aligns with the well-established Sicilian tradition of combining calcareous components and grog, indicating a local tradition of pottery production with no significant compositional differences suggesting specialized production at the workshop level.
Summary of seven Swedish case reports on the microwave syndrome associated with 5G radiofrequency radiation
Authors: Hardell Lennart , Nilsson Mona
Published: June 2024

The fifth generation, 5G, for wireless communication is currently deployed in Sweden since 2019/2020, as well as in many other countries. We have previously published seven case reports that include a total of 16 persons aged between 4 and 83 years that developed the microwave syndrome within short time after being exposed to 5G base stations close to their dwellings. In all cases high radiofrequency (RF) radiation from 4G/5G was measured with a broadband meter. RF radiation reached >2,500,000 to >3,180,000 μW/m2 in peak maximum value in three of the studies. In total 41 different health issues were assessed for each person graded 0 (no complaint) to 10 (worst symptoms). Most prevalent and severe were sleeping difficultly (insomnia, waking night time, early wake-up), headache, fatique, irritability, concentration problems, loss of immediate memory, emotional distress, depression tendency, anxiety/panic, dysesthesia (unusual touched based sensations), burning and lancinating skin, cardiovascular symptoms (transitory high or irregular pulse), dyspnea, and pain in muscles and joints. Balance disorder and tinnitus were less prevalent. All these symptoms are included in the microwave syndrome. In most cases the symptoms declined and disappeared within a short time period after the studied persons had moved to a place with no 5G. These case histories are classical examples of provocation studies. They reinforce the urgency to inhibit the deployment of 5G until more safety studies have been performed.
Pharmacological treatment of pain in Swedish nursing homes: Prevalence and associations with cognitive impairment and depressive mood
Authors: Rankin Linda , Lindkvist Marie , Backman Annica , Sköldunger Anders , Lövheim Hugo , Edvardsson David , Gustafsson Maria
Published: June 2024

Objectives

Chronic pain is highly prevalent in nursing home residents and often occurs with depression as well as cognitive impairment, which can severely influence and limit the expression of pain.

Methods

The present cross-sectional study aimed to estimate the prevalence of pain, depressive mood, and cognitive impairment in association with pharmacological treatment against pain and depressive symptoms among Swedish nursing home residents.

Results

We found an overall pain prevalence of 52.8%, a prevalence of 63.1% for being in a depressive mood, and a prevalence of cognitive impairment of 68.3%. Among individuals assessed to have depressive mood, 60.5% were also assessed to have pain. The prevalence of pharmacological treatment for pain was 77.5 and 54.1% for antidepressants. Prescription of pharmacological treatment against pain was associated with reports of currently having pain, and paracetamol was the most prescribed drug. A higher cognitive function was associated with more filled prescriptions of drugs for neuropathic pain, paracetamol, and nonsteroidal anti-inflammatory drugs (NSAIDs), which could indicate an undertreatment of pain in those cognitively impaired.

Conclusion

It is important to further explore the relationship between pain, depressive mood, and cognitive impairment in regard to pain management in nursing home residents.
The Perception of the “Migrant Threat” in Croatian Gorski Kotar by the Locals and Migrants through the Prism of Visibility and Invisibility
Authors: Ružić Boris , Puljar D’Alessio Sanja
Published: June 2024

Focused on the aftermath of the so-called migrant crisis of 2014 in the Croatian region of Gorski Kotar, this paper presents an analysis of the processes involved in constructing the idea of the “migrant threat” both among the locals whose settlements, towns and villages lie on the path of the people on the move, as well as among the migrants themselves traversing that area. More specifically, we analyze juxtaposed perceptions of threat. For the locals, the threat seems to stem from the visibility of migrants (their presence in a sparsely populated region) layered with the perception of their own invisibility as a result of economic and infrastructural disregard by the state, as well as of the lack of greater military activities at the border. For the migrants, the threat comes from the possibly highly dangerous visibility enforced by different kinds of surveillance technologies, making them vulnerable to documented strategies of expulsion. The paper employs ethnographic fieldwork and a visual analysis of migrant self-representation online to underline the importance of studying migration from an integrated point of view which includes both local and migrant visual and narrative articulation of the same (border) space between the Schengen area and “the other space”. Based on interviews, a review of the socio-political, economic, and cultural aspects of migration today, and a visual analysis of migrant self-representation practices, we show that different spheres of migration (in)visibility cannot be separated.

Precautionary Principle as a Criterion of Accusation in the Criminal Liability of Crimes against the Environment
Authors: Taboada Velásquez Daniel Felipe , Gómez Jaramillo Alejandro
Published: June 2024

This research involves a documentary review regarding different theoretical and doctrinal postulates, according to which the affinity and interference of the precautionary principle as a criterion for imputing criminal liability for environmental damage in Colombia are gauged. In order to elaborate on this topic, it was necessary to make a theoretical assessment of a risk society and how the legal doctrine has valued risk as a criterion of criminal accusation.
In this research, we provided a description and legal analysis of the precautionary principle in environmental matters and defined the parameters under which this principle is measured. In addition, the development and configuration of the environment as a protected legal right, its classification as a fundamental right, and its interference with the right to life and personal integrity are briefly described.
In short, it was necessary to assess and question the scope of malice and its components within the accusation of criminal titles in the scenarios of a risk society and its link with the environmental precautionary principle. All these issues were addressed using descriptive and bibliographic research with a qualitative approach. The criminal liability of those who transgress the principle described above and put the protected legal assets related to the environment at potential risk was analyzed from an objective legal point of view. Likewise, we conducted an in-depth evaluation of the constitutional environmental protection category and the state duties concerning this constitutional mandate.
culpa como presunción de causalidad en la responsabilidad del médico por incumplimiento de su deber de información al paciente
Authors: Calahorrano Latorre Edison Ramiro
Published: June 2024

El presente trabajo analiza el problema de la causalidad incierta entre el incumplimiento del deber de informar del médico y el daño al paciente, partiendo de que este último es de carácter extrapatrimonial y afecta a su autodeterminación. Se plantea la hipótesis de que la culpa constituye la introducción de un riesgo no permitido que permite presumir la causalidad. Para dar soporte a esta hipótesis se analizan, en primer lugar, el incumplimiento de deber de informar como conducta culpable que vulnera la lex artis e introduce el riesgo un permitido que afecta la autodeterminación del paciente; en segundo lugar, los mecanismos para establecer el nexo causal en las omisiones y analizar el papel de los criterios de imputación objetiva de incremento del riesgo y fin de protección de la norma en el caso; finalmente, se concluye que la culpa permite presumir la causalidad entre la omisión de información y el daño extrapatrimonial a la autodeterminación de paciente, ante lo cual el facultativo puede defenderse probando que el daño no le es imputable si su conducta no ha incrementado el riesgo.

To analyze the correlation between leptin and cortisol after a concurrent training (CT) session. Thirty male volunteers (age: 27.7 ± 5.1 years, BMI:  27.08 ± 1.42 kg/m2) were randomly assigned to an experimental group (EG: n=15) and a control group (CG: n=15). Baseline leptin and cortisol levels were determined by collecting blood samples. EG was subjected to CT (indoor cycling followed by strength training), whereas CG performed no exercise. After CT, blood samples were collected in EG and CG to determine the hormone variables. EG showed a significant decrease (p<0.05) intra and intergroup in leptin and cortisol levels. Only the EG showed a significant correlation (r=0.756; p<0.05) between leptin and cortisol levels. CT session is linked to in decreased leptin and cortisol levels, exhibiting a positive correlation between them.

Published: June 2024

The aim of this present study is to investigate the influence of warm-up, physical activity level, and body fat percentages on the reaction time of punches and kicks in adult kickboxing practitioners. The sample consisted of 20 kickboxing practitioners. Physical activity level was evaluated by the International Physical Activity Questionnaire-Short Form, body composition by electrical bioimpedance, and reaction time by the mobile application TReaction. The direct punch and the kick with no warm-up had the highest reaction times (p<0.05) when compared with after warm-up and after the two-minute rounds. There were correlations between kick with no warm-up reaction time and fat percentage (r=0.524; p=0.018), and kick with no warm-up and physical activity level (r=-0.560; p=0.010). The physical activity level and the percentage of body fat are variables that interfere with kickboxers’ kick reaction time. Furthermore, the warm-up had a positive influence on the reduction of the reaction time of punches.

The objective of the study was to evaluate the Self-Assessment of Health (SAH) in elderly individuals before and after participating in a physical exercise program. It was a quasi-experimental study conducted with 96 elderly participants ( = 67 ± 6.07 years) enrolled in a 16-week physical exercise program. Before and after the program, participants filled out a medical history form and the Short Form 36 Health Survey Questionnaire (SF-36). The study found a prevalence of obesity (75.6%), with the predominant health conditions being hypertension (27.08% of the sample) and diabetes (5.21%), while 7.29% reported having both conditions. A notable enhancement in SAH was observed following the completion of the exercise program, both in terms of physical health (∆%= 3.75%, p = 0.0002), mental health (∆%= 17.95%, p = 0.004), and the overall SAH index (∆%= 6.75%, p = 0.001). This suggests the importance of physical exercise programs for the self-assessment of health in elderly individuals.

Authors: Cardoso de Oliveira Rodrigo , Lima Alves Junior Gledson , Martin Dantas Estélio Henrique
Published: June 2024

Coxa valga (CVl) and coxa vara (CVr) are morphological alterations related to the collodiaphyseal angle, which represents the angulation between the femoral neck and the femoral diaphysis. The angle considered normal is 120° to 135°. When the angle is less than 120°, it is called CVr, and when it is greater than 135°, it is called CVl. These alterations affect the musculoskeletal system, impacting the quality of life of those affected. This article aims to highlight the main functional impairments in the skeletal, muscular, and articular systems caused by CVl and CVr. Articles were collected from the MEDLINE and BVS databases, using the descriptors ("coxa valga" OR "coxa vara") in September 2022. Eleven articles were included in the review, with the main results summarized in a PRISMA flowchart. This review highlights the various adverse consequences in the locomotor system associated with the presence of CVl and CVr in affected individuals.

Published: June 2024

La presente investigación pretende determinar la influencia del corcho granulado en las propiedades físicas, térmicas y mecánicas del bloque de concreto. Se realizaron ensayos de absorción, densidad, contenido de humedad, resistencia a la compresión y conductividad térmica a bloques de concreto elaborados artesanalmente, con sustitución de arena por corcho granulado en 3 % y 5 % en dos grupos experimentales, junto con un grupo patrón. Para el caso de las propiedades físicas, la absorción presentó valores promedio de 9.47 %, 8.23 % y 9.37 % para el grupo patrón (BP) y grupos experimentales (BC3 y BC5), respectivamente. Los valores de densidad aumentaron a medida que se incrementó el porcentaje de corcho, con una densidad de 2088.77 kg/m3 para el grupo con 5 % de corcho. En cuanto al contenido de humedad, los valores fueron disminuyendo desde 13.67 % del BP, 11.87 % para BC3 y, finalmente, 9.23 % para BC5. La propiedad mecánica de resistencia a la compresión presentó variaciones de aumento y disminución con valores de 19.53 kg/cm2 para el grupo BP, 23.10 kg/cm2 para el grupo BC3 y 16.21 kg/cm2 para el grupo BC5. Por último, para el ensayo de conductividad térmica, los resultados disminuyeron según lo esperado, con valores de 0.387 W/mK, 0.3164 W/mK y 0.3036 W/mK para los grupos BP, BC3 y BC5, respectivamente. Estos datos procesados con las pruebas estadísticas mostraron que la incorporación de corcho granulado en el bloque de concreto tiene una influencia significativa en sus propiedades físicas, térmicas y mecánicas.
Thoughts on the entanglement of electromagnetism and life: A theoretical study
Authors: Zsarnovszky Attila
Published: June 2024

Dissection of the matter into its constituents leads us to the smallest particles that we know. These particles form a material structure that is determined by the electromagnetic field generated and carried by those particles. Changes in any of the two major constituents leads to changes in that material system, be it a living organism or a lifeless object. The latter statement carries the mystery of life that is born from a continuous and programmed series of system changes fuelled by an energy source with a yet unknown functioning mechanism. The present work is a theoretical approach towards the understanding and potential discovery of the aforementioned, not-yet-known cellular energetic mechanism. Understanding the energetic basis of intracellular biochemistry is equally important in human and animal therapeutics. Additionally, as all such discoveries offer novel solutions in various fields of the global industry, the final outcome of this theoretical work also brings about the idea of a new discovery in electronics industry.

Two distinct treatment cocktails were examined: 3p-hpRNA (5′ triphosphate hairpin RNA) combined with unmethylated CpG oligonucleotide (CpG); CpG in combination with OX40 receptor-specific monoclonal antibody (anti-OX40). Treatment efficacy was assessed using a murine model of kidney adenocarcinoma.

Renca cells (renal cortical cells with adenocarcinoma) were subcutaneously engrafted in 30 BALB/c mice, then animals were allocated into three treatment groups: Group 1: CpG+anti-OX40, Group 2: CpG+3p-hpRNA, Group 3: untreated control. Treatment efficacy was evaluated based on tumour growth, the occurrence of metastases and overall survival.

On day 28 post-implantation, experiments had to be terminated due to tumour progression. Although comparisons of survival times and primary tumour sizes thus became inconsequential, histological examinations provided valuable insights. We observed distinct variations in primary tumour characteristics among the different groups: Groups 1 and 2 displayed demarcations, while Group 3 exhibited diffuse tumours with necrosis. Lung metastases were evident in 70% of untreated mice, whereas none were observed in either of the treated groups.

Our findings instil confidence in the potential efficacy of the treatments, thereby laying a solid foundation for future investigations.

Published: June 2024

An experimental study is conducted to investigate the effect of adding metal-foam (MF) blocks into the annular
region of a double-tube heat exchanger. The experiments were performed for different volume flow rates, from 25 to
50 LPH using hot and cold water as the working fluid. Hot water and cold water are maintained at 65 and 31°C,
respectively. Nickel metal foam with 10 pores per inch (PPI) and 0.9 porosity is fitted in the annular space. The primary
objective of this research is to assess the impact of metal foam on key parameters such as heat transfer coefficient,
effectiveness, pressure drop, and friction drop by comparing it with a conventional double-tube heat exchanger. Results
demonstrate that the incorporation of metal foam leads to a significant improvement in effectiveness and efficiency, and
as a consequence, the overall heat transfer coefficient values are 2.2 times compared to a conventional heat exchanger. However, this enhancement in heat transfer comes at the cost of increased pressure drop across the metal-foam heat exchanger. Following a comprehensive performance evaluation, the study reveals that the metal-foam heat exchanger exhibits a significant enhancement in heat transfer capability per unit pressure drop, showcasing a twofold increase compared to conventional heat exchangers. Additionally, the experimental results are compared with established correlations from existing literature. Overall, this research contributes to the ongoing efforts to advance solar thermal technologies by providing empirical evidence of the effectiveness of metal foam in enhancing heat transfer within flat-plate collectors. The findings offer valuable insights for the design and optimization of solar energy systems aimed at maximizing energy conversion efficiency and sustainability.

Introdução: o impacto que a pandemia causou na vida das pessoas foi muito grande, tanto no âmbito psicossocial quanto no profissional e está relacionado a algumas síndromes e/ou transtornos psicológicos, como exemplo a Síndrome de Burnout. Objetivo: verificar a relação entre a pandemia do Covid-19 e a síndrome de Burnout em professores da educação básica de escolas públicas e privadas. Métodos: trata-se de uma revisão narrativa, onde se utilizou as principais bases de dados para analisar em literatura ampla o tema abordado na pesquisa, sem que se limite à sistematização. Resultados: foram discutidas as mudanças do ensino no contexto da pandemia da Covid-19 e os impactos na saúde mental dos profissionais da educação. Essas mudanças, como a reorganização da rotina, o ajuste na estrutura do ensino, mudanças pedagógicas e o acesso ao ensino online por todos, foram geradoras de estresse nos professores e nos alunos. E a responsabilização exclusiva dos professores para que mantivessem a qualidade no ensino durante a pandemia, associada à ausência de capacitações, foram fatores relevantes para o adoecimento dos profissionais. Conclusão: pesquisas sobre a Síndrome de Burnout em professores de escolas públicas e privadas mostraram que fatores ambientais e individuais quando somados podem desencadear a síndrome de Burnout, como, a falta de estrutura física adequada, instrumentos de trabalho adequados, insatisfação profissional, exaustão emocional, contribuindo para o adoecimento.

O estudo de comunidades de aves em áreas verdes urbanas é de fundamental importância para o conhecimento dos impactos da urbanização sobre o meio ambiente. Assim, o estudo teve como objetivo o levantamento da comunidade de aves de remanescentes fragmentados de Mata Atlântica no ambiente urbano do município de Santa Cruz do Sul. A pesquisa foi realizada entre outubro de 2021 e abril de 2022, com dois levantamentos por estação do ano, em cada uma das três áreas de amostragem. Foram registradas um total de 104 espécies de aves, distribuídas em 44 famílias. As famílias mais representativas foram Tyrannidae, Thraupidae e Furnariidae, grupos cujas espécies são mais tolerantes a ambientes urbanizados. No total, 87 espécies (83,6%) foram classificadas como residentes, e as demais 17 espécies (16,3%) como residentes de verão. Quanto à estrutura alimentar das áreas amostradas, a guilda com maior número de representantes foi a onívora (n=37), seguida da insetívora (n=35). Em relação a riqueza de espécies nas áreas amostradas, verificou-se um maior número de registros na área 2 (n=80). A estação do ano que apresentou o maior número de espécies totais foi a primavera (n=97). Todas as áreas apresentaram elevado número de espécies classificadas como espécies pouco comuns. Em todas as áreas de amostragem a curva de suficiência amostral estabilizou-se após o segundo levantamento do Verão. A grande diversidade de espécies encontradas nas áreas de amostragem corrobora com a importância das áreas verdes no ambiente urbano para a biodiversidade local.

Published: June 2024

INTRODUÇÃO: As políticas de saúde infantil da Atenção Básica preconizam pela perspectiva do cuidado integral, associadas ao princípio da territorialidade. Contudo, abarcar a diversidade do território constitui-se enquanto um importante desafio para os profissionais de saúde responsáveis pelas consultas periódicas dos bebês, sobretudo em locais com forte tradição cultural hegemônica. OBJETIVO: O presente estudo buscou investigar as experiências e desafios de profissionais de saúde com a diversidade de cuidadores, saberes e práticas de cuidado nos atendimentos a bebês de 0 a 2 anos na Atenção Básica de Caxias do Sul, RS. MÉTODO: Trata-se de um estudo qualitativo envolvendo entrevistas online com 12 profissionais de saúde de quatro UBS da cidade, cujos dados foram analisados através de uma leitura psicanalítica. RESULTADOS e DISCUSSÃO: Constatou-se que há uma diversidade de cuidadores nas consultas dos bebês, sobretudo mães italianas, avós italianas e cuidadores imigrantes não italianos. Ainda, as consultas acabam se tornando um palco de embates entre profissionais e cuidadores, especialmente no tocante às dissonâncias sobre os saberes e práticas de cuidado ao bebê. CONCLUSÃO: Os saberes dos cuidadores que não estão em consonância com as políticas de saúde são percebidos pelos profissionais de saúde enquanto desafios na efetivação do cuidado integral dos bebês.

The objective was to evaluate the effects of including different proportions of Wet Brewery Residue (WBR) using inoculants on rehydrated ground corn silage quality. The experiment was conducted in a completely randomized design in a 4 x 3 factorial scheme with four replications. Four combinations of WBR and ground corn were evaluated to achieve 45 (DM45), 50 (DM50), 55 (DM55), and 65% (DM65) of dry matter (DM) in the homogenized material before siling, and three types of inoculation: without inoculant, with L. plantarum + P. acidylactici (Homo) and with L. buchneri (L. B). Ensiling was done in experimental PVC silos (±4.0kg) and stored for 180 days. The variables obtained were analyzed by the analysis of variance and regression procedures (P<0.05) using the R software. The percentage of real DM included in the treatments was 47%, 52%, 56%, and 66%. No impairment of the pH-reducing capacity of corn rehydrated with WBR was observed. Total dry matter losses were within the acceptable limit in silage with 52% DM (DM50), regardless of the type of inoculation. Gas losses were within the permissible limit only in the DM50 treatments with Homo inoculant and in the DM50 treatment without inoculation. Effluent losses were outside the tolerable limit in the treatment with 47% DM (DM45) in the presence of the inoculant LB. There was a significant interaction between the inoculant LB and the silages, with 47% (DM45) and 56% (DM55) DM for the Crude Protein (CP) levels. The ADF and NDF variables reduced linearly as a function of the increase in dry matter of the ensiled material, with a tendency for the lowest values to be found in treatments without inoculation. For all variables, an increase in energy levels (Non-Fibrous Carbohydrates, starch, Total Digestible Nutrients, and Net Energy gain) was observed with the increase in the DM content of the silage. It is concluded that silage with 52% DM (DM50) obtained the best results for fermentative losses. For bromatological and energetic characteristics, silage with 66% DM was the best, except for the CP variable, where 47% DM silage achieved superior results. In general, the addition of additives did not show any improvement in relation to treatments without inoculants.
