The future of cooperative programs in Europe, paradox of a hybrid market
Authors: Bellais Renaud
Published: April 2023

For European arms-producing countries, launching a cooperative program represents a compromise between preserving their domestic industrial base and achieving an affordable acquisition. Nevertheless, scientific literature is marred with criticisms regarding the effectiveness of such an approach. Paradoxically, this does not prevent European states from committing to new cooperative programs—the European Commission has set up mechanisms for improving the effectiveness of European defense industry based, de facto, on incentives to launch cooperative programs. This article looks at the place of cooperative programs in Europe to understand whether the new initiatives of the European Union can succeed in improving the effectiveness of military spending as well as enhancing European strategic autonomy. It analyzes the organization of the European armament market to explain why cooperative programs appear unavoidable. It explores how the European Commission could overcome current limitations through community-funded programs, given that such funding would foster the emergence of a European defense technological and industrial base.
Woman as the Embodiment of Desire in Algirdas Landsbergis’ Short Stories
Authors: Bankauskaitė Gabija , Vaišvylaitė Domantė
Published: April 2023

The woman as the embodiment of desire in the writings of Algirdas Jeronimas Landsbergis (1924–2004) – a Lithuanian expatriate playwright, novelist, editor, and literary and theatre critic – is not an ordinary literary character but symbolises the unique relationship between the rational world of consciousness and the instinctive, primal needs expressed in creative fantasies. The image of the woman-fantasy appears in the author’s short stories. It allows us to explore the inherent egocentricity of desire, the experience of lust that constrains subjectivity. C. G. Jung’s philosophy is used to classify fantasy images and identify their characteristic features, while E. Husserl’s phenomenology of consciousness is applied to the description of the protagonists’ experiences in the process of unique emotional occurrences. Short stories “Duet for Female Voice and Violin in Venice”, “A Long Night”, and “The Second Mountain Range” are analysed as expressions of the experiencing consciousness and the creating unconscious. The desires and fantasies of the protagonists materialise into a woman who is seen as a creation of lust; her body is reified by demonstrating power. However, a phantasmatic metamorphosis of characters is powerless to solve their dilemmas and inner confusion, as lust is based on one-sided, searching, and striving relations with the world in the absence of any answer.

The program of computations of spectrum of the geomagnetical field is developed. It was confirmed, that the most values of tension of the geomagnetical field at magnetic storms arise up on frequencies below 1 Hz. On the basis of an algorithm developed the characteristics of the super low-frequency geomagnetic field at the frequency range < 1 Hz are calculated. The analysis at frequencies 0.1, 0.5, 0.01, 0.05, 0.001, 0.0001 Hz allows to reveal the largest intensity of the low-frequency geomagnetic field at 0.0001 Hz. Its oscillation rate is most sensitive for biological organisms to the magnetic storm occurrence. Some examples of influencing of low frequency fluctuations of the geomagnetical field on biological objects are considered. The ways of their computations are given. Biological objects which can possess sensitiveness to influences of the weak magnetic fields are considered. The results obtained are used to consider some aspects of the mechanism of the low-frequency geomagnetic field influence on biological objects.

The presented paper investigates common call center challenges ranging from management to software and agents. Service quality is a complex and multifaceted construction that has a major impact on customer acquisition, retention and loyalty. Because there are a few different factors that influence service quality, call center managers must know what they are before they can work to optimize them. As an important part of any business is communication, both within the organization and with customers and clients, a feature-rich, advanced Private Branch Exchange (PBX) phone system is of great benefit. Call Centers are one of the most commonly used implementations of PBX systems in businesses of any type, shape and size. We suggest an efficient and secure solution for collecting, processing, storing, analyzing and visualizing data from call centers. The proposed approach is driven by applying the type of IP PBX engine based on Asterisk. AWS cloud hosted clustering approaches and load balancing system algorithms have been studied in order to mitigate progressively growing load indicators as we add more customers and thus real data sources to the system. The ELK Stack has been chosen as the optimal approach: it is open source and covers a need in the log management and analytics space. The proposed solution will help to automate the call flow process, where it is necessary, based on the analysis of the collected call centers data. The monitoring results obtained along with the particular call center structure knowledges gives us an opportunity for improving call strategies such as ACDs and IVRs, filling agent's knowledge gaps, eliminating the absence of well-defined practices of call handling, etc. It also eliminates the need to hire additional staff or outsource call centers to share the load.

Authors:   General Energy Institute of NAS of Ukraine, 172, Antonovycha St., Kyiv, 03150, Ukraine, Denysov Viktor
Published: April 2023

Description of the developed software and information complex for modeling autonomous heat supply systems provided, which allows optimizing the selection of units and their operation modes and ensuring the production and redistribution of thermal energy in accordance with the schedule of consumers. Optimized modes simulation operation of the autonomous heat supply system for a cottage village based on local energy resources with minimal use of external energy sources performed. The use of software and information complex made it possible to calculate the parameters that provide optimal coverage of the heat load schedule of a cottage settlement based on local energy resources. For the calculation, the predicted values of the installed thermal power of the units and the heat load graph which was obtained by adapting the real annual graph of the external temperature of Stockholm to the geographical location of the Kyiv region were used. The developed new software and information complex provide an opportunity for hourly modeling, research into the optimal modes of operation of heat units, and evaluation of the effectiveness of the use of renewable energy sources in autonomous heat supply systems. In the developed software and information complex, the model of optimization of operating modes is applied, which belongs to the class of problems of optimal loading of generating capacities of power systems with the criterion of minimizing costs for production, accumulation, and consumption of thermal energy. An example of simulation results using a heat load schedule for a selected typical day is presented. The obtained results indicate a decrease in the specific cost of hourly heat supply with an increase in the part of thermal energy supplied at the expense of renewable energy sources. This is due to a decrease in the share of gas, and in general, any other generation based on fossil fuel technologies, in the total volume of heat supply. Thus, the effectiveness of the use of renewable energy sources based on local energy resources as part of the heat supply system of the cottage village was confirmed. Keywords: autonomous heat supply, the efficiency of renewable energy sources based on local energy resources.

An investigation of the flora, mycobiota and lichenized mycobiota associated with the endemic Aotearoa / New Zealand plant genus Lophomyrtus (Myrtaceae) revealed a specimen of Lepra erythrella (Pertusariaceae). Lepra erythrella, though briefly mentioned in a paper documenting the results of that Lophomyrtus study, has not yet been formally admitted into the lichenized mycobiota of Aotearoa / New Zealand. Therefore, to complete that process in this paper, we provide a description based on the collection made from Lophomyrtus and a further one located in the Allan Herbarium (CHR). The addition of Lepra erythrella to the lichenized biota of Aotearoa / New Zealand highlights not only the lack of collecting of this genus in that archipelago but the need to critically examine that nation’s herbarium collections. We recommend that further research on this genus is carried out in our region.

Published: April 2023

Applications that work with data are required to ensure their reliable storage. The interfaces available for working with file systems are not sufficiently specified and require high qualifications for correct use that does not lead to loss of user data. As part of this work, a tool was developed that provides developers with the opportunity to test their applications and identify the most common errors. The tool is based on collecting events from the interaction of the application with the file system and then running checks that can indicate errors. The tool implements a modular architecture that allows you to expand the available set of checks. The developed tool was integrated into the process of testing the implementation of a durable log, similar to the write ahead log, a component implemented in many database management systems. The tool allowed to detect and correct several errors leading to possible data loss.
Comparison of Graph Embeddings for Source Code with Text Models Based on CNN and CodeBERT Architectures
Authors: Romanov Vitaly Anatolyevich , Ivanov Vladimir Vladimirovich
Published: April 2023

One possible way to reduce bugs in source code is to create intelligent tools that make the development process easier. Such tools often use vector representations of the source code and machine learning techniques borrowed from the field of natural language processing. However, such approaches do not take into account the specifics of the source code and its structure. This work studies methods for pretraining graph vector representations for source code, where the graph represents the structure of the program. The results show that graph embeddings allow to achieve an accuracy of classifying variable types in Python programs that is comparable to CodeBERT embeddings. Moreover, the simultaneous use of text and graph embeddings as part of a hybrid model can improve the accuracy of type classification by more than 10%.

Published: April 2023

In the current integration trend, high-tech agriculture is an inevitable direction for agricultural developing countries. In particular, hydroponics is a commonly used farming technique due to many advantages: no soil, space saving, no weeds, easy control of influencing factors, double yield. Hydroponic crop production systems are used worldwide to grow flowers, foliage, litter, and fruit and vegetable crops. Like other farming methods, hydroponics still has problems with pests and diseases that cause serious damage to the harvest that have not been completely resolved. One of the sources of pathogens is the hydroponic solution. Many methods to kill bacteria and fungi in hydroponic solutions have been studied. However, some methods gave low efficiency, others gave high efficiency but it caused secondary environmental pollution. Electrochemical activated solution (EAS), produced from dilute sodium chloride (NaCl) solution, has been wide known as a super disinfectant solution with high ability to kill most bacteria and fungi and is safe for humans. In this study we were forced on determine the ability to control pathogens in hydroponic solution of EAS, the effects of EAS on hydroponic solution properties and the growth of Brassica juncea in the mixed of EAS – hydroponic solution. Difference volume of EAS were added into hydroponic solutions and mixed for 30, 45, 60, 120 or 180 min. The most effective mixed solution (mixed ratio and time) was selected to apply to cultivate Brassica juncea. The results show that EAS has the ability to control pathogens in hydroponic solution very effectively, replacing other harmful chemicals. When increasing the volume EAS added (higher ACC of mixed solution) or the exposure time the TDS and ORP index of hydroponic solution were raised slightly while pH value was slightly dropped and the total coliform counts decreased significantly. The total coliform counts of mixed solutions reduced over the exposed time. However, the increasing rate of killing ability of EAS was decreased (along with ACC of solutions). Meanwhile, there was no obvious change in the nitrate concentration. The most effective mixed ratio EAS: hydroponic solution and exposure time for pathogens control were 2.5:500 with 30 min or 1.5:500 with 90 min. The mixed ratio of 1.5:500 with 90 min of exposure time were recommended because of its lesser changes on the properties of hydroponic solution. The mixed EAS - hydroponic solution did no negative effect to the growth of Brassica juncea in comparison with original hydroponic solution.

Published: April 2023

Ocean radiation monitoring and warning systems are essential in monitoring radioactive species' contamination levels in an oceanic environment and predicting the radioactive materials propagation caused by nuclear incidents in a marine area. Since the Fukushima nuclear disaster, different types of mobile radiation monitoring devices have been investigated based on modern technologies in electronic – communication. Those types of equipment can directly measure the radioactive contamination in the ocean instead of the traditional laboratory method. This study presents a complete process of researching, designing, manufacturing, and integrating a mobile radiation monitoring system (MRMS) in the ocean. The integrated radiation sensor can both measure radiation dose rate and identify radioactive isotopes on a floating device. The measured data from the sensor is processed and displayed on the electronic block by developed software, or it can be transmitted directly to the mainland by one of three different communication devices. This prototype system is the first product in Vietnam in the development of the MRMS, which is highly promising in terms of performance, low cost, and maintenance.

Colletotrichum species cause anthracnose in various tropical crops in both cultivation and postharvest periods. The current synthetic fungicides to treat anthracnose sometime show toxic effects for farmers, residues on foods, and environmental impacts. In this work, turmeric extract containing curcuminoids was used as an active ingredient and formulated into a nanoemulsion to control anthracnose in red pepper and tomato fruits. The nanoparticles containing turmeric extract (25 %) were successfully prepared by encapsulation using Tween-80 and PEG 400 as emulsifiers. Out of the three main curcuminoids in the turmeric extract, BDMC was determined as the most abundant constituent via HPLC analysis. Turmeric nanoparticles showed an average particle size of 203 nm, polydispersity index (PI) of 0.322, and zeta potential of -92.7 mV.  In the in vitro antifungal bioassay, this nanoformulation significantly inhibited the mycelial growth of Colletotrichum gloeosporioides and Colletotrichum orbiculare in a dose-dependent manner. Red pepper anthracnose was also consistently suppressed by turmeric nanoparticles but the tomato anthracnose was resistant to this formulation at 10 mg/mL in vivo. The study results proved the effectiveness of turmeric nanoparticles to control red pepper anthracnose in postharvest preservation and suggested developing the innovative nanoformulation as a green fungicide.

Published: April 2023

ABSTRACT: Pest insects are one of the major factors affecting the productivity of sugarcane, and especially those associated with the soil, which damage the crop if not controlled. There is little information on the insect associated with the soil in the sugarcane crop in the state of Mato Grosso do Sul, Brazil. This study evaluated the occurrence, abundance and population variation of soil-associated insects in sugarcane crops in four counties in the state of Mato Grosso do Sul during a period from September 2009 to August 2010. For the capture of insects, deep in the soil trenches were (50 x 50 x 30 width x length x depth). It was observed that county of Maracaju has a high incidence of soil insects in sugarcane crop. Specimens of the family Scarabaeidae are abundant in sugarcane fields of the state of Mato Grosso do Sul, being Liogenys suturalis the predominant species. Soil insects of the Chrysomelidae family were found with greater abundance in Dourados and Naviraí while Noctuidae, represented only by the Hyponeuma taltula, occurred mainly in Dourados. Insects of the family Termitidae occur in sugarcane fields in the counties of Maracaju and Naviraí but not in Nova Alvorada do Sul and Dourados. Sphenophorus levis and Metamasius hemipterus were alsoreported in the sugarcane fields from Maracaju, being the occurrence these species the first record in the Mato Grosso do Sul State. The determined occurrence of different soil insects in the sugarcane fields may help in their management in the four counties studied.
Light-emitting diodes (LEDs) in development and response to water stress in Eucalyptus benthamii seedlings (Myrtaceae)

Published: April 2023

ABSTRACT: Plants use light as a source of energy in the process of photosynthesis. Different levels of luminosity cause physiological and morphological changes in the plant, and its success depends on its adaptation to these different levels. Light emitting diodes (LED) have been proposed as a light source in controlled environments. The present research evaluated physiological and morphological aspects in Eucalyptus benthamii (Myrtaceae) seedlings kept under different colors of LED lamps and submitted to water stress. The experiment was carried out in a completely randomized design, in which the treatments were defined as: T1 (control, with white light); T2 (blue light); T3 (red light) and T4 (mixed blue and red light). Red light resulted in the best response to most morphological variables in plant growth. In response to water stress, blue light LEDs resulted in a better seedling response, with slower reduction of photosynthetic rate and other variables. This may indicate the possibility of reducing water deficit damage in seedlings acclimated to blue light prior to field planting.

Published: April 2023

ABSTRACT: Bacillus cereus is a Gram-positive bacterium commonly reported in soils and plants that occupy various ecological habitats, and the main source of contamination for cattle is silage. This report described a case of fetal loss associated with B. cereus infection in a cow. An 8-month-old, Nelore female bovine fetus from a beef farm was submitted for necropsy. A gross examination revealed fibrinous pleuropneumonia and fibrin exudation on the liver surface. The morphological diagnosis was restricted to the lungs and liver. In the lungs there was fibrinosuppurative pleuropneumonia associated with numerous aggregates of rod-shaped bacteria. In the liver there was moderate focally extensive fibrinous peri hepatitis.The lungs, liver, thoracic, and abomasal fluid cultures yielded pure cultures of B. cereus, indicating that these bacteria should be recognized as a cause of bovine abortion in fetuses that macroscopically present fibrin in the abdominal and thoracic cavity.

Published: April 2023

ABSTRACT Objectives: Assess whether the spine surgical approach for degenerative diseases can influence the physical capacity of patients and its correlation with cardiorespiratory function. Methods: A prospective study was conducted on 9 patients of both genders, aged between eighteen and sixty, scheduled for spinal surgery for degenerative disease in the lumbar segment. Patients underwent treadmill stress test two times, fifteen days before and sixty days after the surgery. A cardiologist performed the test according to the Bruce protocol with a progressive increase in incline and speed. Results: There were no statistically significant differences between pre- and postoperative assessments for the parameters evaluated in the treadmill stress test. Forty-four percent of patients needed to interrupt the test postoperatively due to dyspnea (p=0.023). Conclusion: The improvement obtained with spinal surgery does not have statistically significant relevance in tiredness, pain, and fatigue in the lower limbs and low back pain. Some patients could not complete the examination after surgery due to poor physical conditioning, and it was necessary to interrupt the examination due to dyspnea.

EFFECTS OF CYCLIC RESISTANCE TRAINING ON LOWER LIMB STRENGTH AND BALANCE IN BASKETBALL ATHLETES
Authors: Huanpin Li
Published: April 2023

ABSTRACT Introduction: Cyclic resistance training allows that at the end of each movement cycle, all parts of the athlete’s body return to the initial position, allowing the constant repeatability of the exercise. It is believed that this activity can significantly influence the physical capacity of the lower limbs of basketball athletes. Objective: Study the effects of cyclic resistance training on basketball players’ lower limb strength and balance ability. Methods: 36 basketball players were selected and randomly divided into experimental and control groups. The experimental group received training for eight weeks combining routine training with cyclic resistance training, while the control group remained with routine training only. Relevant performance, strength, and balance data were analyzed before and after the procedure, undergoing statistical analysis and confrontation with current literature. Results: The peak flexor moment in the experimental group increased from 94.42 ± 28.20 Nm to 101.85 ± 23.30 Nm; the peak torque of the extensor muscle increased from 161.88 ± 39.16 Nm to 186.19 ± 40.29 Nm. In the balance ability test, the left lateral test increased from 68.78 ± 4.65 cm to 74.35 ± 3.29 cm, the left increased from 109.33 ± 7.22 cm to 114.65 ± 7.54 cm. The increase in the control group was small. Conclusion: Cyclic resistance training demonstrated a beneficial effect on both lower limb strength and balance in basketball athletes, and was effective in improving the physical capacity of basketball players.Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

Published: April 2023

ABSTRACT Introduction: Badminton is a sport that demands quick decision-making and abrupt changes of direction, demanding high performance in the explosive strength of the players’ lower limbs. It is believed that the exercise of resistance in the players’ lower limbs may reflect a better performance on the court. Objective: Study the lower limbs resistance exercise effects on badminton players’ performance. Methods: 24 active badminton players were selected and randomly divided into control and experimental groups. While the control group continued the practice of existing training methods, the experimental group included lower limb strength exercise, with increased lower limb resistance with an elastic band completing the lower limb resistance exercise. Results: Before the experiment, the execution time of four points at the center of gravity was 16.83 ± 0.75 s in the experimental group and 17.15 ± 0.62 s in the control group, resulting in 15.40 ± 0.21s in the experimental group and 15.82 ± 0. 48s in the control group. The hurdle test period also changed from 10.21 ± 0.65s to 10.02 ± 0.62s in the experimental group, and from 10.82 ± 0.29s to 10.46 ± 0.32s in the control group.

Authors: Zhao Liulin
Published: April 2023

ABSTRACT Introduction: Chinese martial arts constitute an integral sport, demanding high capacity and physical fitness from its athletes. It is believed that functional balance training can enhance the performance of its athletes, as it strengthens and tones the muscles, stimulating the active proprioception of the executed movements. Objective: This paper investigates the effect of balance training on martial arts athletes and its impact on the execution of complex sports movements. Methods: Under experimental control, 100 martial arts athletes were selected and divided into two groups without statistical differences to perform the experiment. The experimental group added balance training, while the control group followed the usual training script. Sports fitness indices were measured before and after the intervention for statistical analysis. Results: The data regarding the balance index of the experimental group pre was 7.00±0.52, and after the experiment, it went to 8.40±0.47; the functional indices increased from 7.50±0.55 to 8.46±0.42. No statistically relevant changes were found in the control group. Conclusion: Functional balance training can complement daily training routines for greater benefits in martial arts athletes. The improvement of active proprioception statistically increases the ability of its practitioners in the execution of complex movements.

ABSTRACT Introduction: Maintaining body composition and physical fitness is important for the well-being of college students. Recent data indicate an increase in obesity among young college students and new techniques have been studied to control this situation. Among the current resources is high-intensity interval training. Objective: Explore the effects of high-intensity interval training on physical fitness and body control in obese male college students. Methods: The experimental control involved 100 obese male college students, divided into experimental and control groups. The experimental group participated in a high-intensity interval training protocol while the control group performed general aerobic training. Data before and after the experiment, which lasted 12 weeks, were collected and statistically analyzed. Results: The conditions of male college students in the experimental group were statistically improved, and the fitness index changed expressively. The sitting forward bending increased from 5.91±5.16 to 9.47±5.27, the standing balance index with eyes closed increased from 5.87±5.58 to 10.47±6.08, the long jump index went from 1.96±0.15 to 2.14±0.21, in the supine sitting position it went from 19.97±8.46 to 31.24±9.42, and the running time in 50 meters was reduced from 9.61±1.53 to 8.53±1.25 s. Conclusion: High-intensity interval training positively impacted both physical fitness and body composition in obese college students.

Objetivo: analisar os fatores associados ao uso inconsistente do preservativo masculino entre homens HIV negativos que fazem sexo com homens. Método: estudo transversal, analítico, de abrangência nacional realizado on-line em todas as regiões do Brasil, em 2020, por meio de redes sociais e em sites de relacionamento. O uso inconsistente do preservativo foi definido como uso ocasional ou nunca ter usado. Foram realizadas análises estatísticas descritivas, testes de associação e regressão logística binária. Resultados: o uso inconsistente do preservativo foi relatado por 1222 (85%) dos 1438 participantes. As variáveis “homossexuais” (ORA: 2,03; IC 95%: 1,14- 3,59; p = 0,016), “ter parceiro fixo” (ORA: 2,19; IC 95%: 1,55-3,09; p<0,001), “sexo oral” (ORA: 2,41; IC 95%: 1,31-4,43; p = 0,005), “anal insertivo” (ORA: 1,98; IC 95%: 1,10-3,58; p = 0,023) e “diagnóstico de IST” (ORA: 1,59; IC 95%: 1,13-2,24; p = 0,007) foram independentemente associadas ao uso inconsistente do preservativo masculino. As variáveis “recebeu aconselhamento de amigo sobre teste de HIV” (ORA: 0,71; IC 95%: 0,52-0,96; p = 0,028) e “profissional do sexo” (ORA: 0,26; IC 95%: 0,11-0,60; p = 0,002) foram fatores de proteção. Conclusão: as variáveis estudadas apontaram uma forte relação das parcerias fixas com o aumento da confiança e uma baixa adesão ao uso do preservativo, o que corrobora com outros estudos.

ABSTRACT Nitric oxide (NO) is an important mediator responsible for vasodilation in pulmonary hypertension (PH) in humans. Based on human literature, it is suggested that in dogs there is also NO production decrease in lung tissue in the presence of PH with hypoxia. Therefore, the aim of this research was to determine the indirect plasmatic NO concentration in dogs with PH secondary or not to the left-side heart disease (LHD) and also with low, intermediate and high probability of PH to characterize the NO involvement on PH in dogs. Blood samples were collected from 35 dogs with probability of PH to NO measurement. NO concentration was estimated by the nitrite/nitrate concentration, and it was significantly different (p=0.002) in dogs with PH secondary to LHD (median=14 µM, range 11.19-16.59) and not secondary to LHD (median=25.88µM, range 15.08-36.71). However, this was not significant for the probability of low, intermediate, and high PH, although there was a tendency for NO concentration to be higher in dogs with high PH. The results of this study demonstrate that there is release of NO in dogs with PH, as well as that its dosage could differentiate dogs with PH secondary to LHD from dogs with non-secondary PH.

ABSTRACT Developing countries face great challenges to couple agricultural intensification and sustainable supply chain development. This paper explores the opportunities for innovation in the conservation of the locally adapted Curraleiro Pé-Duro (CPD) cattle. The CPD is a historical Brazilian breed, related to regional culture, which exhibits remarkable adaptability in tropical biomes. The research method consisted of interviewing and analyzing the discourse of CPD breeders in Tocantins, Brazil. The systematization of the data resulted in four categories and eleven subcategories, which were defined a posteriori. Our findings reveal motivational aspects, potentialities, and prospects for valuation, besides the needs and perceived challenges faced by CPD farmers. A better understanding of the current situation may guide public policies, encourage stakeholders, benefit farmers, and lead to sustainable agri-food initiatives. The empirical contributions of our diagnosis are discussed, and we show how they bring forward and provide valuable lessons to prospect innovations in the conservation of CPD cattle. These findings may support scholars and people who are also interested in accessing and supporting the conservation of indigenous livestock. In general, the study supports the definition of strategies, planning, and investments for the value chain, including the participation of upstream and downstream segments of the farms.

ABSTRACT The study was carried out with the objective of evaluating the effects of using phytase levels at different energy densities in the diet of broilers, from 28 to 35 days of age. The experimental diets contained increasing levels of apparent metabolizable energy corrected for nitrogen balance and different levels of phytase. Growth performance variables, nutrient digestibility, as well as variables related to bone integrity were examined. Diets containing 500 FTU/kg in combination with 3150kcal.kg-1 of AMEn resulted in better growth performance. Supplementation with 500 and 1000 FTU/kg in the diets provide better coefficients of apparent and ileal digestibility of calcium and phosphorus, but negatively influence the deposition of calcium, phosphorus, dry matter, and ash in the tibia, in addition to adversely affecting the breakage and area of these bones in broilers. Bone length and the levels of magnesium and zinc present in the tibias were not influenced by the energy and phytase levels of the diets. There is no interaction between the different energetic densities and the phytase doses in the variables analyzed in the studied period. Increasing the energy density of diets resulted in improved apparent and ileal digestibility for most nutrients.
