Motu Proprio. Amt und Ich des Papstes
Authors: Deckers Daniel
Published: April 2021

Unter den vielen Titeln, mit denen das Amt des Bischofs von Rom seit der Antike ausgeschmückt wurde, dürfte im deutschen Sprachraum keiner bekannter sein als der, den der Dramatiker Rolf Hochhuth im Jahr 1963 popularisiert hat: Der Stellvertreter wurde zum Stigma einer Institution namens Kirche, deren Oberhaupt die eigenen Vollkommenheits- wie Machtansprüche durch sein Handeln nicht nur dementiert, sondern auf alle Zeiten hin diskreditiert hat.

Das Material, aus dem der Essay für die Publikation kondensiert wurde, stellt dabei weniger eine schlichte Langversion dar, sondern hat als Text jenseits des Publizieren einen eigenen Stautus.
Barriers to the implementation of point-of-care ultrasonography by physiotherapists in haemophilia treatment centres in Canada: a modified Delphi approach
Authors: Strike Karen , Chan Anthony , Maly Monica R. , Solomon Patricia
Published: April 2021

Background

In patients with haemophilia, evidence suggests that the physical examination alone is not sensitive enough to detect small amounts of blood within a joint. Attention has shifted to methods of improving the sensitivity of the physical examination through adding diagnostic modalities such as point-of-care ultrasonography (POC-US). Proficiency with the physical examination and understanding of the role of POC-US are important competencies for physiotherapists. Despite training, implementation of POC-US by physiotherapists in haemophilia treatment centres in Canada has been mixed.

Aim

Using a theory-based approach, the aim of the current study is to achieve expert consensus regarding the barriers to physiotherapy performed POC-US in haemophilia treatment centres in Canada using a modified Delphi approach.

Materials and Methods

Using the Knowledge-to-Action Framework and the Consolidated Framework for Implementation Research (CFIR), a modified Delphi approach was completed using the Modified BARRIERS Scale (MBS). Participants were blinded and consensus was reached over three rounds at the Canadian Hemophilia Society’s annual three-day conference.

Results

Twenty-two physiotherapists participated; 20 participants completed Round 1, and 21 completed Rounds 2 and 3. Four items of the MBS reached consensus: 1) The physiotherapist does not have time to read research related to POC-US; 2) The physiotherapist is isolated from knowledgeable colleagues with whom to discuss POC-US; 3) Administration will not allow POC-US implementation; 4) There is insufficient time on the job to implement new ideas. All four consensus items can be mapped to one domain of the CFIR: the inner setting.

Conclusion

The haemophilia treatment centre within a healthcare organisation appears to be an important target for addressing barriers to the implementation of physiotherapy performed POC-US.
Blood pressure in haemophilia and its relation to clotting factor usage
Authors: Gopal Srila , Barnes Richard FW , Quon Doris V , Sun Hao Wei Linda , Jackson Shannon , von Drygalski Annette
Published: April 2021

Background

Patients with haemophilia have a higher prevalence of hypertension than the general population that cannot be explained by traditional cardiovascular risk factors such as age, race, diabetes or obesity. Patients with severe haemophilia, who are on clotting factor prophylaxis, have a higher prevalence of hypertension compared to patients with milder forms of haemophilia, who infuse clotting factor less frequently. This raises the question of whether there is a link between clotting factor usage and blood pressure in haemophilia patients.

Methods

Data was collected from 193 patients with severe haemophilia presenting to three haemophilia treatment centres in the United States and Canada, including age, body mass index (BMI), blood pressure (BP), Hepatitis C (HCV) and Human Immunodeficiency Virus (HIV) infection status, and clotting factor usage from pharmacy prescriptions (units/kg/year). The correlation between BP and factor usage was examined using quantile regression models.

Results

Systolic and diastolic BP plotted against factor use showed a cone-shaped scatter of points. There was no association between clotting factor usage and higher systolic or diastolic BP.

Conclusion

Our observations provide no evidence for an association between increased clotting factor usage and high BP.
Qualitative Adjectives in EFL Students’ Reflective Writing Essays
Authors: Deveci Tanju , Ayish Nader
Published: April 2021

Qualitative adjectives are often used in expressive writing, including reflective writing. They express and (de)intensify feelings and emotions, thereby expressing stance. This study investigates the adjective profiles of 60 first-year EFL students’ reflective essays and compares male and female university students’ utilization of qualitative adjectives and those used as attitudinal stance markers. Data were collected from a reflective writing task after students participated in a seminar on effective listening. Analyses were conducted considering the General Service List (GSL), the Academic Word List (AWL), and words that do not appear in either of the preceding lists. The results indicated that qualitative adjectives accounted for 6% of the words in these reflective writing essays, and the male students used a greater number of adjectives than the female students. This difference, which was at a statistically significant level, likely stems from male students’ greater use of adjectives from the Academic Word Lists. The results also showed that 47.5% of the adjectives used in these essays were attitudinal. There was no statistically significant difference between the frequencies with which the male and the female students used these attitudinal adjectives. The results are discussed and recommendations are made to increase students’ effective use of adjectives in reflective writing.

Tropical gar (Atractosteus tropicus) is an ancestral subtropical fish species in southeastern Mexico, which has great potential as a model species for physiological, biomedical and genomic studies. The quantification of gene expression through RT-qPCR is one of the most commonly used techniques, due to its precision, sensitivity and high performance, particularly in gene expression to compare between cells, tissues and organs; as well as different populations, stages of development, metabolism, among other conditions. This study analyzed the stability and normalization of six commonly used reference genes such as alpha elongation factor (ef1-α), beta-actin (actb), 18S ribosomal RNA (18s rrna), beta-2-microglobulin (b2m), tubulin alpha (α-tub) and glyceraldehyde 3-phosphate dehydrogenase (gapdh) in the different tissues of the intestine, muscle, gill, stomach, brain and liver in adult males of A. tropicus from reared in captivity through three BestKeeper, geNorm and NormFinder algorithms. Based on our results we can conclude that in the three BestKeeper, NormFinder and geNorm algorithms, the most stable genes are ef1, followed by 18s rrna and actb where the gene stability will depend on specific tissue to analyze in tropical gar A. tropicus adults.

PATENT TROLLING AND LEGAL REGULATION OF ARTIFICIAL INTELLIGENCE (EXPERIENCE OF THE UNITED STATES OF AMERICA)
Authors: Barabashev A. G. , Ponomareva D. V.
Published: April 2021

The article deals with a unique legal phenomenon that requires regulation in the context of protecting the rights of inventors to the results of scientific activity — patent trolling. Due to the imperfection of the patent system and patent legislation, the subjective rights of “bona fide inventors” in the field of scientific and innovation activities are constantly violated by “patent trolls”. On the example of the law enforcement practice of the United States of America, legal methods of countering this phenomenon are illustrated, the conditions conducive to its occurrence are analyzed. A conclusion is presented on the need to take into account the experience of the United States when amending the legislation of the Russian Federation on patent protection. It is noted that in the era of the fourth industrial revolution, the issue of combating “unscrupulous” copyright holders becomes one of the most acute. The criteria for assessing the “bad faith” of a patent infringement claim, developed by an American legislator, can become the basis for the development of similar legal norms on Russian soil and throughout the post-Soviet space.

Authors: Vasko A.
Published: April 2021

The purpose of this article is to study the possibilities of using operational-search information in criminal proceedings in the Slovak and Czech Republics. The author analyzes the current legislation on the issues under study in the context of criminal procedure law. The purpose of the study is to analyze and justify the possibility of using the results of operational investigative activities in criminal proceedings, mainly in the collection of evidence in both countries. Comparing the legal norms, the author came to the conclusion that the use of operational-search data is possible and applicable in the criminal proceedings of the Slovak Republic, including as evidence. In the Czech Republic, the current situation is different: operational data cannot be used as evidence. At the same time, preparations are currently underway to amend the legislation. Under the current circumstances, it can be expected that the importance of operational investigative data in criminal proceedings in both countries will increase.

Hypothesis/aims of study: Infection of the amniotic cavity and placenta is one of the leading causes of adverse pregnancy outcomes. In the majority of cases, intra-amniotic infection is associated with the normal microbiota of the lower urogenital tract. The aim of the study was to explore the relationships between the placental inflammatory changes, vaginal microbiota and labor course.
Study design, materials and methods: We examined 124 women at 37-41 weeks of gestation. The vaginal discharge at admission was taken for microbiological evaluation, with the delivered placenta sent for histological examination.
Results: In 17.7% of cases, histological examination of the placenta revealed inflammatory changes. A statistically significant correlation was noted between the placental inflammatory changes and Staphylocossus spp. presence in the vaginal discharge at admission (р = 0.0004). The placental inflammatory changes were associated with the membrane rupture to delivery interval more than 6 hours (р = 0.01) and the labor duration more than 7 hours (р = 0.0004). Prelabor rupture of membranes did not significantly affect the placental inflammatory changes (p = 1.0).
Conclusion: Predisposing factors for the development of ascending bacterial infection of the placenta are an abnormal vaginal microbiota with the presence of opportunistic bacteria before delivery, a long membrane rupture to delivery interval, and a prolonged labor.

Authors: Ziganshin Aydar M. , Bektasheva Ilnara I. , Mudrov Viktor A.
Published: April 2021

One of the main causes of maternal mortality is obstetric bleeding, among which 2/3 of cases are bleeding in the early postpartum period. The existing methods of preventing and stopping uterine bleeding in the postpartum period do not always allow achieving the desired result due to the ineffectiveness of the measures taken. The aim of this study was to assess the effectiveness of existing uterotonic drugs in the obstetric bleeding prevention and treatment. We performed a detailed systematic analysis of modern domestic and foreign literature on uterotonic drugs being used to prevent and stop obstetric bleeding, with their main parameters considered. The study used such information databases as eLIBRARY.RU, Scopus, PubMed, MEDLINE, ScienceDirect, and Cochrane Library from inception to December 2020. Despite a significant number of studies devoted to exploring the possibilities of uterotonic drugs, currently there are no methods with absolute therapeutic efficacy, which requires research to develop new drugs based on their synthetic analogues.

Hypothesis/Aims of study: According to the number of oocytes retrieved in IVF/ICSI protocols, the ovarian response to controlled ovarian stimulation is divided into: poor (03 oocytes), suboptimal (49 oocytes), normal (1015 oocytes) and excessive (15 oocytes) response. However, the effectiveness of IVF / ICSI programs in women with a suboptimal response is poorly understood, since this cohort of patients is often fallen into the category of women with a normal response. The aim of this study was to determine the main characteristics of IVF / ICSI programs in patients with suboptimal response to be further compared to those in women with normal response to controlled ovarian stimulation.
Study design, materials and methods: This retrospective study included 568 patients: 470 women with suboptimal response and 98 women with normal response to controlled ovarian stimulation. The comparative analysis comprised clinical and anamnestic data, as well as the main characteristics of assisted reproductive technology programs in the selected clinical groups.
Results: It was found that patients with suboptimal response to controlled ovarian stimulation had significantly more frequent history of pelvic surgery (71.3 % vs. 55.1 %; p 0.01) and pelvic inflammatory diseases (70.9% vs. 60.2%; p 0.05). Parameters of ovarian reserve (serum anti-Mllerian hormone level and antral follicle count) in women with suboptimal response were significantly lower (p 0.001). In addition, the number of mature oocytes, 2PN zygotes, good quality embryos (p 0.001), as well as the clinical pregnancy rate in women with suboptimal response were found to be significantly lower than in patients with normal response to controlled ovarian stimulation (27.2% vs. 41.7%; p 0.01). It was noted that concomitant uterine fibroids enhanced the negative impact on the effectiveness of IVF / ICSI programs in women with suboptimal response to controlled ovarian stimulation (OR = 0.5; 95% CI: 0.30.9; p = 0.03). ROC analysis identified predictors of suboptimal response to controlled ovarian stimulation, such as serum anti-Mllerian hormone level (AUC = 0.80) with the cut-off value of 2.57 ng / ml (sensitivity 74%, specificity 75%) and antral follicle count (AUC = 0.90) with the cut-off value of 10 follicles (sensitivity 80%, specificity 94%).
Conclusion: In women with suboptimal response to controlled ovarian stimulation, IVF / ICSI success rates are significantly reduced when compared to those in women with normal response. Concomitant uterine fibroids may further decrease the effectiveness of IVF / ICSI protocols in patients with suboptimal response. Predictors of suboptimal response include the serum anti-Mllerian hormone level and antral follicle count.

Published: April 2021

The article briefly presents the literature data and a description of the clinical dynamic observation of a patient with severe hypoxic brain damage (from the neonatal period to 4 months of life), in the conditions of the neonatal intensive care unit. The article describes the clinical picture, features of paroxysmal states and antiepileptic therapy, dynamics of neuroimaging data, electroencephalographic phenomena recorded in a patient with cerebral depression and structural cerebral injuries. The significance of electroencephalographic examination in the intensive care unit as an informative method for assessing cerebral activity in young children with central nervous system depression syndrome is shown. Disorganization of background activity, indicating structural cerebral damage, long-term persistence of slow-wave activity, detection of epileptic changes in the form of generalized flashes of pointed waves in the theta range, alpha-coma pattern, subsequently replaced by suppression of the background pattern in the patient, are typical electrophysiological disorders recorded in severe hypoxic encephalopathy. In conditions of limited opportunities for visual diagnosis of a patient with impaired consciousness, EEG remains the only method of obtaining information about the functional state of the brain, the data obtained during the study are an important prognostic criterion.

Introduction. According to the commonly accepted classification, geographical division of the Southern Near-Aral region (Karakalpakstan, Republic of Uzbekistan) is determined by the distance from the epicenter of the formal Aral Sea ecological disaster. The physique development was compared in male youngsters living in Zone No. 1 (critical), Zone No. 2 (stable) and Zone No. 3 (normal). The aim was a comparison of body length and mass in male youngsters up to 17 years old living in all three zones.

Material and methods. Total body length and mass were studied in 320 male volunteers, age 1719. Z-index of body length and body mass index (BMI) were estimated according to the standards of WHO Growth Reference, 2007. Batch-to-batch variations were studied with KruskalWallis test, and MannWhitney criterion including Bonferroni correction for multiple comparison. Categorical features were compared using Fishers exact test for 33 contingency tables with calculating the proportion of children with one or another deviation in body weight. The results were considered statistically significant at p 0.05.

Results. Subjects from Zone 1 possessed significantly lower valued of BMI and Z-index. The incidence of Z-index values lower than mean (less 1 SD) were significantly higher in Zone 1 (critical).

Conclusion. The results may be explained by via chemical pollution of the environment by the endocrine-disrupting chemicals in the critical zone of the Aral See region ecological disaster and can be implied for the health monitoring of the local population.

Published: April 2021

Among skin diseases in children and adolescents, the most common pathology is acne. The main pathogenetic link of acne in adolescents is hormonal imbalance. The effect on the sebaceous glands of high concentrations of dihydrotestosterone causes a change not only in the quantitative but also in the qualitative composition of the sebaceous secretion. The study is devoted to assessing the characteristics of sexual development, immune status and biochemical parameters in boys suffering from acne. Materials and methods.

Materials and methods. A comparative analysis of the state of immunity, sexual development, biochemical parameters of 147 boys suffering from acne, and 142 healthy boys who do not suffer from acne.

It was found that the immune status of boys suffering from acne was characterized by a decrease in cytotoxic lymphocytes. In the peripheral blood of these boys, serum interferon , tumor necrosis factor , interleukins 1, 2, 8 and 10, as well as small circulating immune complexes were significantly higher than in the boys of the control group. In boys suffering from acne, in the puberty period, the concentration of prolactin in 1314 years is significantly lower, and testosterone levels are significantly higher than in boys of the control group of the same age. At 1517 years of age, the concentration of luteinizing hormone in boys with acne is significantly lower, and testosterone is higher than in boys in the control group. Evaluation of the degree of formation of secondary sexual characteristics indicates that boys suffering from acne differed from their peers from the control group by a small advance in sexual development. Thus, boys suffering from acne, characterized by advanced and disharmonious puberty.

Published: April 2021

One of the mandatory stages of introducing new drugs into obstetric practice is preclinical trials, the purpose of which is to study the effect of drugs on the development of fetuses and placentas. When conducting experimental studies, the main group of animals receiving the drug is compared with the control group of animals that do not receive drugs. At the same time, the volume of the test drug itself can significantly change the blood volume (BV) of an experimental animal, especially a small one, and such administration repeated repeatedly over several days can accumulate this effect, having an adverse effect on the functional state of the fetus. A model of chronic placental insufficiency created on the 18th day of pregnancy in female rabbits by ligating 1/3 of the preplacental vessels in one uterine horn was used to study the effect on the development of the brain and placenta of normally developed and retarded fetuses of multiple daily (1928 days of pregnancy) infusions of saline solution to females in a volume of 6% of the animals BV and comparable to the volume of medications used in the treatment of placental insufficiency in clinical practice (main group of rabbits). It was found that repeated daily administration of saline solution to a female rabbit in the second half of pregnancy, which is about 6% of the BV, causes a violation of the functional state of her normally developed and, to an even greater extent, retarded fetuses. This is manifested by a 1.4-fold reduced survival rate of fetuses in the intact horn of the uterus and a more pronounced violation of brain metabolism in fetuses of the intact and experimental horns compared to those of the control group of females.

Authors: Fedorova Maria V.
Published: April 2021

Background: The analysis carried out and the forecasted development prospects of the Vsevolozhsk municipal district show the high socio-economic importance of this territory for St. Petersburg and the Leningrad region. This territory is intensively developing, new residential zones are being formed on it, enterprises are opening, new jobs are being created, and recreational zones are being organized. Active housing construction in the municipalities "City of Vsevolozhsk" and "Zanevskoye rural settlement" is accompanied by a significant increase in the population. According to the forecast, in 2041 the population of the municipal formation "City of Vsevolozhsk" will exceed 100 thousand people, of the "Zanevsky rural settlement" - 180 thousand people. The population of the municipalities of St. Petersburg included in the gravitational zone of the maglev transport line in the direction "Vsevolozhsk - St. Petersburg", in 2041 will increase by 1.4 times compared to 2015, amounting to 520 thousand people. The listed tendencies indicate that in the future the intensity of traffic flows will grow and the demand for the use of maglev passenger transport will increase.
Aim: Putting into operation lines of magneto-transport vehicles in places of concentration of growing passenger flows, which will help to reduce travel time, meet freight requirements, improve the quality and increase travel safety when driving along dedicated lanes.
Method: We have described the existing transport service system in Vsevolozhsk. The survey of passenger traffic on bus routes operating between Vsevolozhsk and St. Petersburg was carried out by two methods during the periods of morning and evening peaks, as well as during the inter-peak period: visual method and tabular method. The article gives a characteristic of the uneven distribution of passenger traffic at the Ladozhskaya metro station and the socio-economic characteristics of the pedestrian accessibility zone of stopping points, identifies the maximum passenger traffic and the need for rolling stock.
Results: As the basis for the development of the transport system of urban agglomerations, it is proposed to use magnetolithic transport. For its operation, a special high-speed infrastructure and a new rolling stock are needed. In other words, there is a need for the development and economic evaluation of projects for the construction and operation of magnetolithic transport lines in the formation and implementation of transport strategies of modern urban agglomerations.

Especialmente a partir dos fundamentos filosóficos sobre a linguagem pensados por Bakhtin e o Círculo russo (Volóchinov e Medviédev), propõe-se analisar os sentidos do discurso coaching financeiro no enunciado vídeo publicitário,“Meu nome é Bettina”, publicado em março de 2019 no canal da Empiricus, no Youtube, e viralizado nas redes sociais. A hipótese de pesquisa é que o discurso coaching financeiro presente no enunciado vídeo “Meu nome é Bettina” ancora-se no diálogo com os discursos de autoajuda e neoliberal, para a realização da comunicação discursiva. No enunciado vídeo “Meu nome é Bettina” observa-se que, por meio do discurso coaching financeiro, o enunciado vídeo faz circular o enriquecimento fácil do e autocentrado no indivíduo, apresentando ser constituído de relações dialógicas com discursos produzidos pelo capitalismo, com ênfase no individualismo, como os discursos de autoajuda e neoliberal. Destaca-se, ainda, o cotejo de outros enunciados que circularam no Twitter que respondem ao enunciado vídeo “Meu nome é Bettina”, de modo a ilustrar a característica da responsividade do enunciado na esfera midiática.
Reeditar é preciso? As cartas oficiais norte-rio-grandenses e os corpora diacrônicos
Authors: De Melo Felipe Morais
Published: April 2021

São bastante estreitas e profícuas as relações entre a Linguística Histórica e a Linguística de Corpus, sobretudo a partir da década de 90, quando a primeira ganha fôlego renovador no Brasil, tendo na edição de corpora diacrônicos uma das motrizes basilares para seu progressivo desenvolvimento. Sob o signo desse entrelaçamento entre as duas áreas, este trabalho, através da análise de conteúdo, apresenta um caso de reedição de corpus diacrônico, as cartas oficiais norte-rio-grandenses (1713-1950), e, por meio de pesquisa bibliográfica, propõe algumas reflexões acerca do contato entre esses dois campos de estudo no Brasil e dos impactos, positivos e negativos, do meio digital nessa conexão. O artigo revela como alterações nas orientações de uma investigação podem justificar um processo frutífero de reedição e evidencia tanto riscos éticos quanto aprimoramentos funcionais a que esses corpora estão sujeitos devido a fatores como a tecnologia e a internet, propondo, ao final, que haja maior visibilidade das questões levantadas no estudo.
Sabores do progressivo na România Nova

Published: April 2021

Neste artigo, analisamos a perífrase perfectiva progressiva (PPP) no português brasileiro (PB) e no espanhol argentino (EA), de modo comparativo. Baseado em testes linguísticos, fazemos duas afirmações sobre a PPP em comparação com a perífrase imperfectiva progressiva. Em primeiro lugar, afirmamos que a PPP tem significado progressivo e perfectivo. Em segundo lugar, afirmamos que a PPP permite leituras iterativas quando combinada com eventos télicos (achievements no PB e no EA e accomplishments somente no EA). Propomos uma análise sintático-semântica que dá conta dessas observações de um modo composicional: ao passo que a forma do gerúndio expressa o significado progressivo (presente em ambas as perífrases), o auxiliar na PPP expressão um significado perfectivo que permite a leitura iterativa observada nessa perífrase.
Ischemic and hemorrhagic stroke: a comparative evaluation of lipid profile
Authors: Saproo Nipun , Singh Roma
Published: April 2021

Background: The scientific community often sees association of blood lipid levels with the risk of cardiovascular disease. Strong association has often been found between high levels of low density lipoproteins (LDL) and the development of atherosclerosis while elevated levels of high density lipoproteins (HDL) are understood to play protective role. This study was conducted to compare lipid profile among ischemic and hemorrhagic stroke patients.

Methods: This observational study was conducted in Department of Neurology, Medanta, Medicity Gurugram, where 50 patients’ cases of infarct and 50 cases of hemorrhagic stroke were studied during: April 2020 to October 2020. All patients with clinically and radiologically proved cerebrovascular accident were included in the study.

Results: Mean total cholesterol (TC) for hemorrhagic and ischemic stroke was 175.2 mg/dl and 192.4±41.6 mg/dl respectively. Deranged LDL among subjects with ischemic stroke was 32%. Deranged LDL was seen in 76% of patients reporting ischemic stroke. The mean values for triglycerides (TG) stood at 122±34.6 mg/dl and 141±43.3 mg/dl for hemorrhagic and ischemic stroke respectively. It was seen that the risk of developing ischemic stroke increased with rise in total cholesterol and LDL value. Lipid derangement thus formed an important risk factor for stroke.

Conclusions: A significant association is found between raised LDL, abnormal HDL and ischemic stroke, however, a significant rise in total cholesterol level was found in case of both the groups. It is very apparent that patients under high risk should be regularly screened for serum lipid profile.

The establishment of new forest plantations requires making important decisions starting with the selection of the species to be planted, as well as the choice of an adequate planting spacing to guarantee the maximization of wood production. The aim of this study was to evaluate the performance of nine eucalypt species planted with three different spacings under the environmental conditions of the tropical dry forest of the inter-Andean valleys of Colombia. A split-plot arrangement with two replicates was used as the experimental design. The planting spacing factor (three planting spacings) was assigned to the main plots and the species factor (nine eucalypt species) was assigned to the subplots. Survival and growth were evaluated at twenty-four months of age. The study identified the Brazilian provenances of Eucalyptus camaldulensis Dehnh, Eucalyptus urophylla S.T. Blake, Eucalyptus grandis W. Hill, and Eucalyptus pellita F. Muell. and the Colombian provenance of Eucalyptus pellita F. Muell. as promising for commercial reforestation programs  in areas with a water deficit in the tropical dry forest. Planting spacings of 3×2 m (1666 stems·ha-1) and 3×2.5 m (1333 stems·ha-1) maximized the production of basal area and the volume for the species evaluated. Finally, no interaction was detected between species and planting spacing factors, therefore, the species identified had a better performance regardless of the planting spacing used.
