Authors: Gutierrez Rapalino Bleydis Paola , Domínguez Haydar Yamileth Del Carmen
Published: April 2017

Seed dispersal is a key process in the re-establishment of vegetation on reclaimed lands. The aim of this study was to determine the contributions of the ant species Ectatomma ruidum and Pheidole fallax to seed dispersal and germination on reclaimed lands in the Cerrejón coal mine, Colombia. Four 6 x 40 m plots were installed in each area, in which the number of nests by species was counted and distances between closest nests of each species were measured. Five of the nests counted were chosen for seed extraction, and a nearby control sample was taken from each nest. In total, 295 nests were counted: 59 nests during the dry season and 236 nests during the rainy season, of which 84 belonged to P. fallax and 211 belonged to E. ruidum. A total of 21 304 seeds were found in nests and control samples, of which 19 349 were obtained from P. fallax nest refuse, and 318 were obtained from E. ruidum nests; 597 seeds were found in control samples. The number of seeds extracted from nests was significantly higher than the number of seeds removed from control samples. There was a significant difference between the number of seeds removed by P. fallax and the number of seeds removed by E. ruidum. The seed germination percentage from nests was higher than the percentage from seeds in control samples. In the case of P. fallax, the germination percentage was lower in control samples and higher in nests and refuse. The results suggest that the ant species E. ruidum and P. fallax may contribute to seed dispersal and re-establishment of vegetation in areas where they were found. These ants may thus significantly contribute to restoration processes in areas degraded by mining.
Cercariae (Digenea: Strigeidae, Diplostomidae) in Biomphalaria straminea (Planorbidae) from a rice field in Northeastern Argentina
Authors: Fernández Maria Virginia , Hamann Monika Inés
Published: April 2017

The rice fields can provide habitats for many species of aquatic invertebrates, as insects, molluscs, crustaceans; and vertebrates, as fish, amphibians, reptiles and birds, which may act as hosts in the life cycles of digenean parasites. In this context, the goal of the present study was to describe the cercariae found in Biomphalaria straminea from a rice field in Northeastern Argentina. This freshwater snail inhabits a wide variety of environments, favoring shallow, temporary and standing or slow-flowing freshwater bodies. For this study, snails were collected from the cultivated parcels and irrigated channels during the flooding periods (from the time of sowing to soon after harvesting of the rice) between December 2010 and May 2011 and December 2011 and April 2012, in a rice field from Corrientes province, one of the main rice producers of Argentina. A total of 5 510 snails were examined of which 26 were infected with three different larval trematodes belonging to Strigeidae, Furcocercaria V (0.40 %) and Furcocercaria XX (0.04 %), and Diplostomidae, Furcocercaria XIX (0.04 %). Furcocercaria XX and Furcocercaria XIX were present in one rice cultivation cycle, while Furcocercaria V was present in both rice cultivation cycles. The prevalence of the different furcocercariae was somewhat higher in the second rice cultivation cycle. The cercariae described are new records for Argentina that added to 53 cercariae previously reported for Biomphalaria spp. in different aquatic environments of country. The study of the digenean larval in rice fields is important because contribute to the knowledge of the biodiversity of these environments.
Objectively measuring subjectively described traits: geographic variation in body shape and caudal coloration pattern within Vieja melanura (Teleostei: Cichlidae)
Authors: McMahan Caleb D. , Kutz Justin , Murray Christopher , Chakrabarty Prosanta , Geheber Aaron , Elias Diego
Published: April 2017

Vieja melanura is a Neotropical cichlid occurring in the Petén-lake district systems of Guatemala, as well as the Río Grijalva-Usumacinta basin, and other systems in Southern México, Belize, and Guatemala. A caudal stripe, extending forward from the caudal peduncle, is characteristic of this species. This stripe is sloped downward in nearly all individuals of V. melanura, but the degree of the slope is highly variable throughout its range. The slope and shape of the stripe has previously been used in diagnosing and differentiating between species of Vieja. The purpose of this study was to use objective methods to investigate morphological variation in the caudal stripe and body shape throughout the range of V. melanura. We studied geometric morphometric analyses of body shape and empirical measurements of the slope of the caudal stripe in 215 specimens of V. melanura. We also used the mitochondrial cytochrome b marker to study population level patterns within V. melanura. Results from our analyses showed significant geographic variation in body shape and patterns of coloration with little mitochondrial phylogeographic structure. These patterns likely correspond to differences in riverine habitats throughout the species’ distribution. In conclusion, these results can be used to inform other studies of color and shape variation as it applies to taxonomy and systematics.
Efecto de la temperatura y la acidificación en larvas de Strombus gigas (Mesogastropoda: Strombidae)
Authors: Chavez Villegas Jose Francisco , Enríquez Díaz Martha Rosalía , Aldana Aranda Dalila
Published: April 2017

The increase in CO2 emissions produces heating and reduced pH in the oceans, which may have negative effects on many marine organisms. This is particularly important for those with calcified structures such as the molluscs and their larval stages. We studied Strombus gigas larvae, a gastropod of commercial importance in the Caribbean Sea, in order to know the effect of water temperature and acidification on their development, growth, mortality and calcification during the larval period. A larval culture with triplicate samples was carried out employing four treatments of temperature and pH (Control = 28 °C - pH 8.1, T1 = 28 °C - pH 7.6, T2 = 31 °C - pH 8.1 and T3 = 31 °C - pH 7.6) in August 2015. We registered hatching (No. of eggs – No. of larvae hatched) and organs development, while shell growth and mortality ratio were evaluated over time. Shell calcification was studied in 30 days old larvae using EDX and RAMAN analysis. Our results showed that organs development and shell growth were higher at 31 °C treatments (initial size of 230 ± 4.12 to 313.27 ± 11.34 µm, and final size from 829.50 ± 11.33 to 1 054.50 ± 11.13 µm; from T1 to T2 respectively), and the same pattern was recorded for hatching time (18 hr) and mortality rate (~ 57 %). The Calcium proportion (% wt) was similar between treatments (34.37 ± 10.05 to 37.29 ± 16.81 % wt). Shell Raman analysis showed aragonite in all experimental treatments, with the highest values in the control (1 039.54 ± 780.26 a.u.). Calcite was detected only in 31 °C treatments (174.56 ± 127.19 a.u.), while less intensity of aragonite and calcite were registered at pH 7.6. In conclusion, S. gigas could be adapted to ocean future predictions, however, shell biomineralization processes can be affected.
Bibliometrics of Honduras publications in the Science Citation Index Expanded
Authors: Monge-Nájera Julián , Ho Yuh-Shan
Published: April 2017

Honduras is the second largest country in Central America, but 63 % of its population lives in poverty and it is the Central American country with less scientific journals. Even though Honduras has been included in general studies about Latin American science, there are no specific bibliometric studies about the productivity of the country, so this is the first formal study about the most productive institutions, fields and authors in Honduras. The Science Citation Index Expanded (SCI-EXPANDED), Web of Science Core Collection was used to collect the bibliographic data. There are no Honduras publications from 1903 to 1972 in SCI-EXPANDED. Honduras publications from 1973 to 2015 were further analyzed. A total of 1 146 Honduras publications with 13 document types in the Science Citation Index Expanded from 1973 to 2015 were found. Nearly 95 % of the articles in the database are in English, suggesting that articles in this language have the greatest visibility in the database, similar to other Central American countries. The countries with which Honduras publishes (e.g. Mexico, other Central American countries) follow the geographic and cultural affinity model, i.e. researchers tend to collaborate with colleagues that have similar culture or that are geographically close. This pattern has been found for other Central American countries. The focus of Honduran scientists in health and agriculture problems is typical on the less developed countries; on this respect Honduras is more similar to its closest neighbor, Nicaragua, than to smaller but more developed Central American countries like Panama and Costa Rica. Overall, the situation of scientific research and output in Honduras is improving, with more articles and citation in the SCIEXPANDED, and this positive trend should bring about benefits for the people of Honduras.
High selfing capability and low pollinator visitation in the hummingbird-pollinated epiphyte Pitcairnia heterophylla (Bromeliaceae) at a Costa Rican mountain forest
Authors: Rios Luis Diego , Cascante-Marín Alfredo
Published: April 2017

Pitcairnioideae is the second most diverse subfamily of bromeliads (Bromeliaceae), a group exclusive to tropical regions of the New World. Pitcairnioid bromeliads have floral traits assumed to promote outcrossing through biotic pollination systems; however, the reproductive biology of most of the species of this group has not been documented. Pitcairnia heterophylla is an epiphytic (seldom saxicolous) bromeliad occurring from Southern Mexico, into the Northern Andes. We studied the pollination and breeding system of P. heterophylla in an epiphytic population at a mountain forest in Costa Rica from January to April 2013. We performed hand pollination experiments (agamospermy, autonomous self-pollination, hand self-pollination and hand cross-pollination) on 89 flowers from 23 individuals (3–6 flowers per individual) in 2013 flowering season. Nectar production was measured on 18 unvisited flowers of six individuals with a hand-held refractometer. Simultaneously, floral visitors were recorded on eight individuals with trail cameras for a total of 918 hours (115 ± 52 hours per individual, mean ± SE). Under natural conditions, seed set (540.4 ± 55.2) was similar to manually selfed flowers (516.3 ± 41.5) and autonomously selfed flowers (521.1 ± 29.0), but lower to manually outcrossed flowers (670.2 ± 31.3). The flowers of P. heterophylla are self-compatible, capable of autonomous pollination, and non-agamospermous. Intrafloral self-pollination is facilitated by adichogamy and lack of floral herkogamy. The scentless red flowers of P. heterophylla with tubular corollas and nectar production suggested ornithophilic pollination which was confirmed by video recording of 46 hummingbird visits. The most common floral visitor was the short-billed hummingbird Lampornis calolaemus which accounted for 78 % of the visits. However, the visitation rate during the flowering season was low (0.6 visits per day per plant). Selfing in P. heterophylla might be explained as a mechanism of reproductive assurance and to reduce interspecific pollen flow with taxonomically unrelated plants.

Effects of fly ash amendments, Ralstonia solanacearum, Meloidogyne incognita and Phomopsis vexans on the growth of Solanum melongena
Authors: Khan M. , Siddiqui Z. A.
Published: April 2017

Effects of fly ash amendments in soil (0%, 25% and 50% vol/vol), Ralstonia solanacearum, Meloidogyne incognita and Phomopsis vexans were observed on the growth, chlorophyll and carotenoid contents of eggplant. Addition of 25% fly ash in soil caused a significant increase in plant growth, chlorophyll and carotenoid contents over plants grown without fly ash. However, amendments of 50% fly ash in soil had an adverse effect on the growth, chlorophyll and carotenoid contents of eggplant. Inoculation of the pathogens caused a significant reduction in growth, chlorophyll and carotenoid contents. Inoculation of R. solanacearum caused the greatest reduction followed by P. vexans and M. incognita. Root galling and nematode multiplication was reduced with the increase in fly ash. Wilting and blight indices were 3 in plants grown in 0% and 25% fly ash amended soil while 4 in 50% fly ash amended soil.

Published: April 2017

This article was migrated. The article was not marked as recommended. IntroductionIdentifying learning needs and gaps among faculty is an important and crucial step in the educational process. A well designed and targeted needs assessment provides information useful to identify and meet learners needs in medical education and professional improvement. In reflecting on one's practice in general, the ability to identify weaknesses by self-assessment can serve the function of helping the clinician identify learning needs and set appropriate learning goals. In this study, we utilized a competence score based on self-assessment to identify and prioritize the needs in clinical case management and procedural skills among pediatric anesthesiologists ahead of the opening of a new pediatric hospital in the middle-east. MethodsInstitutional approval was obtained. Content areas covering clinical management and procedural skills were developed based on a systematic literature review and a modified Delphi process. Questionnaires listing the content areas were sent to respondents. The respondents indicated on a modified Dreyfus self-rated expertise scale of 1-10, their current level of expertise versus their ideal level of expertise for each content area. A need score for each content area was calculated from the difference between ideal and current level of expertise with a maximum need score of 9. Descriptive statistics were performed.ResultsThe responses rate was 100 % (21/21). Two thirds of respondents were anesthesia specalists (fellows) and the rest staff anesthesiologists. The modified Dreyfus scale was found to be a relevant, internally consistent (Cronbach's alpha = 0.85) and valid tool for assessing perceived levels competency/expertise of anesthesiologists and anesthesia specialists. Management of malignant hyperthermia, premature infants, difficult airway demonstrated the highest needs with scores; 5.3, 4.4 and 3.8 respectively. Ultrasound use, one lung ventilation and use of difficult airway devices had highest need scores for procedural skill; 5.3, 5.2 and 4.4 respectively. Respondents preferred one to one discussions and workshops as effective methods for improving skills.ConclusionsWe have demonstrated the use of a novel tool, the need score to identify and prioritize needs in a needs assessment for a new program. The information we have gathered is preliminary and further assessments are needed to validate our findings by external reviews and use of focus groups. Our study methodology provides information for immediate in this context but should be translatable for use in other clinical situations in medicine.

ABSTRACT Objective To compare children with attention-deficit/hyperactivity disorder (ADHD), before and after the use of methylphenidate, and a control group, using tests of working memory, inhibition capacity and mental flexibility. Methods Neuropsychological tests were administrated to 53 boys, 9–12 years old: the WISC-III digit span backward, and arithmetic; Stroop Color; and Trail Making Tests. The case group included 23 boys with ADHD, who were combined type, treatment-naive, and with normal intelligence without comorbidities. The control group (n = 30) were age and gender matched. After three months on methylphenidate, the ADHD children were retested. The control group was also retested after three months. Results Before treatment, ADHD children had lower scores than the control group on the tests (p ≤ 0.001) and after methylphenidate had fewer test errors than before (p ≤ 0.001) Conclusion Methylphenidate treatment improves the working memory, inhibitory control and mental flexibility of ADHD boys.

Published: April 2017

Abstract Acute diverticulitis of the colon is a common indication for computed tomography, and its diagnosis and complications are essential to determining the proper treatment and establishing the prognosis. The adaptation of the surgical classification for computed tomography has allowed the extent of intestinal inflammation to be established, the computed tomography findings correlating with the indication for treatment. In addition, computed tomography has proven able to distinguish among the main differential diagnoses of diverticulitis. This pictorial essay aims to present the computed tomography technique, main radiological signs, major complications, and differential diagnoses, as well as to review the classification of acute diverticulitis.

Published: April 2017

ABSTRACT Objective: to assess the conversion rate of Plastic Surgery meeting abstract presentations to full manuscript publications and examine factors associated with this conversion. Methods: we assessed the abstracts presented at the 47th and 48th Brazilian Congresses of Plastic Surgery by cross-referencing with multiple databases. We analyzed the Abstracts' characteristics associated with full manuscript publications. Results: of the 200 abstracts presented, 50 abstracts were subsequently published in full, giving the conference a conversion rate of 25%. The mean time to publish was 15.00±13.75 months. In total, there were 4.93±1.63 authors per abstract and 67.8±163 subjects per abstract; 43.5% of the abstracts were of retrospective studies; 69% comprised the plastic surgery topics head and neck, and chest and trunk, and 88.5% had no statistical analysis. Overall, 80% of the manuscripts were published in plastic surgery journals, 76% had no impact factor and 52% had no citations. Bivariate and multivariate analyses revealed the presence of statistical analysis to be the most significant (p<0.05) predictive factor of conversion of abstracts into full manuscripts. Conclusion: the conversion rate found from this bibliometric research appeared a bit lower than the conversion trend of international plastic surgery meetings, and statistical analysis was a determinant of conversion success.

Published: April 2017

ABSTRACT The Gestational Trophoblastic Disease includes an interrelated group of diseases originating from placental tissue, with distinct behaviors concerning local invasion and metastasis. The high sensitivity of the serial dosages of human chorionic gonadotrophin, combined with advances in chemotherapy treatment, have made gestational trophoblastic neoplasia curable, most often through chemotherapy. However, surgery remains of major importance in the management of patients with gestational trophoblastic disease, improving their prognosis. Surgery is necessary in the control of the disease's complications, such as hemorrhage, and in cases of resistant/relapsed neoplasia. This review discusses the indications and the role of surgical interventions in the management of women with molar pregnancy and gestational trophoblastic neoplasia.

ABSTRACT Background: Computed tomography volumetry (CTV) is a useful tool for predicting graft weights (GW) for living donor liver transplantation (LDLT). Few studies have examined the correlation between CTV and GW in normal liver parenchyma. Aim: To analyze the correlation between CTV and GW in an adult LDLT population and provide a systematic review of the existing mathematical models to calculate partial liver graft weight. Methods: Between January 2009 and January 2013, 28 consecutive donors undergoing right hepatectomy for LDLT were retrospectively reviewed. All grafts were perfused with HTK solution. Estimated graft volume was estimated by CTV and these values were compared to the actual graft weight, which was measured after liver harvesting and perfusion. Results: Median actual GW was 782.5 g, averaged 791.43±136 g and ranged from 520-1185 g. Median estimated graft volume was 927.5 ml, averaged 944.86±200.74 ml and ranged from 600-1477 ml. Linear regression of estimated graft volume and actual GW was significantly linear (GW=0.82 estimated graft volume, r2=0.98, slope=0.47, standard deviation of 0.024 and p<0.0001). Spearman Linear correlation was 0.65 with 95% CI of 0.45 - 0.99 (p<0.0001). Conclusion: The one-to-one rule did not applied in patients with normal liver parenchyma. A better estimation of graft weight could be reached by multiplying estimated graft volume by 0.82.

Published: April 2017

RESUMO O treinamento físico é uma estratégia importante para a saúde de pessoas que vivem com HIV/AIDS; contudo, suas respostas a curto prazo ainda não foram amplamente estudadas, o que limita o entendimento dos efeitos e da segurança da prescrição do treinamento para essa população. Portanto, objetivou-se revisar sistematicamente as respostas agudas decorrentes do exercício físico em pessoas com HIV sobre variáveis fisiológicas e imunológicas. Para isso, foi realizada uma revisão sistemática a partir de trabalhos indexados nas seguintes bases de dados: Medline, Lilacs, Scielo, Web of Science e Science Direct. Os descritores utilizados foram: acquired immunodeficiency syndrome, HIV, AIDS, seropositive, acute session, short, physical activity, exercise, training. As buscas foram realizadas em fevereiro de 2015 e atualizadas em dezembro de 2015 e foram conduzidas sem restrição de datas de publicação ou idioma específico. Foram incluídos para esta revisão artigos que avaliaram as respostas agudas decorrentes de algum modelo de prescrição de treinamento físico envolvendo exercícios aeróbicos, com pesos ou combinados (exercícios aeróbicos e com pesos) relacionados com variáveis fisiológicas e imunológicas em pessoas infectadas pelo HIV. Foram encontrados 2.422 títulos, dos quais, após exclusão das duplicatas e a aplicação dos critérios de elegibilidade, foram selecionados sete artigos para síntese qualitativa. De acordo com os resultados reportados pelos estudos há evidências de que, imediatamente após a realização do exercício físico, ocorre um aumento do número de células circulantes, incluindo leucócitos totais, neutrófilos, monócitos e linfócitos T CD8+ em pessoas infectadas pelo HIV. Além disso, também se observaram alterações significantes nas concentrações de lactato, triglicerídeos, epinefrina e norepinefrina imediatamente após a realização do treinamento aeróbico, independentemente do uso de TARV e/ou de hiperlactatemia. No entanto, não há evidências suficientes para afirmar que o treinamento físico seja totalmente seguro e eficaz para esta população.

Published: April 2017

ABSTRACT Purpose: To explore financial alternatives to implement PV power generation projects based on the provisions of Normative Resolution n. 482/2012 of the Brazilian Electricity Regulatory Agency (Aneel). This regulation sets forth the general conditions to the access of micro- and minigeneration granted to the electric energy distribution systems through the energy product offset method. Originality/gap/relevance/implications: This paper discusses the need for regulatory changes, greater government participation in the granting of financial and tax incentives so that PV solar power technology in distributed generation can be financially viable for residential consumers. Key methodological aspects: Investment analysis in PV systems used the Net Present Value (NPV) valuation method. The research assessed two scenarios for Grid-Connected PV Systems (GCPVSs), with different solar power usage levels for a residential consumer. Summary of key results: The results point to a low financial viability in the implementation of distributed microgeneration projects, suggesting the need to remove the tax burden and reduce financing costs. Key considerations/conclusions: The study shows the need of flexibilization of the Brazilian regulatory model, with changes that enable the expansion of renewable energy offers, with positive economic outcomes for tariff affordability. Tariff benefits from distributed microgeneration can positively reflect on captive customers, provided that investment risks are reduced.

Abstract Objectives: To evaluate the influence of the socioeconomic factors on the alpha-tocopherol concentration in maternal serum. Methods: a retrospective, observational, cross-sectional study with the participation of 103 adult parturient volunteers attended at Hospital Universitário Ana Bezerra (Ana Bezerra University Hospital) in Santa Cruz - Rio Grande do Norte. 5.0 mL of blood was collected from each participant in fasting before the delivery to extract alpha-tocopherol of the serum. Socioeconomic and demographic information were obtained by a previously structured questionnaire. Alpha-tocopherol serum was determined by a High-Performance Chromatography Liquid (Cromatografia Líquida de Alta Eficiência (CLAE). Results: The average concentration of alpha-tocopherol in the serum was 1281.4 (594.8) µg/dL, and 6% of the women presented vitamin E deficiency (DVE). Most pregnant women aged between 18 and 24 years (59%), marital status was married or consensual marriage (77%), elementary schooling complete (34%), low family income (74%) and living in the urban area (73%). No significant differences were found in the alpha-tocopherol concentration according to socioeconomic characteristics and none of the studied factors were associated to the presence of DVE ( p >0.05). Conclusions: The maternal social characteristics were not determinants for the alpha-tocopherol serum and DVE. Further investigations should be carried out during lactation to assess which factors may be involved in the presence of this deficiency.

Abstract Objectives: to analyze the implementation of initiatives and environments promoting healthy feeding as well as the practice of physical activity in public and private schools in Recife. Methods: the schools selected in the City of Recife (n=39) are part of the sample in the Study of Cardiovascular Risks in Adolescents (ERICA). The degree of implementation was estimated by means of interviews with the school manager emphasizing the following components: community participation, presence of healthy environments, partnership with the health segment, monitoring of nutritional status and nutrition policies. The variables selected were assigned points whose sum rated them as satisfactory implementation, poor implementation and critical implementation. Results: the promotion of healthy eating as well as the practice of physical activity was satisfactorily implemented in 13.8% of public schools. However, no private schools obtained such rating. Public schools, when compared to private schools, showed themselves to be more structured, concerning the policies and environments promoting healthy eating and school community participation, however, they showed greater fragility regarding the promotion of physical activity practice and nutritional status monitoring. A few schools had satisfactory implementation in the partnership with the health segment. Conclusions: public and private schools have presented barriers which compromise the full implementation of initiatives and environments promoting healthy eating and physical activity practice.

Abstract Objectives: to assess the concurrent validity of kyphosis index measured in the flexicurve from the correlation of X-rays exams, identifying its accuracy and to assess the thoracic spine in children and young people. Methods: 31 young people at an average age of 11.1±3.4 years were evaluated by digital x-rays: (1) Cobb angle (ÂngCobb), (2) Kyphosis index (KIX), and (3) KIX angle (ÂngKIX). These were measured from the flexicurve design on the millimetric graph paper: (1) Kyphosis index (KIFint), obtained from C7 the intersection of kyphosis-lordosis, (2) Kyphosis index (KIFT12), obtained between C7 and T12, and (3) Kyphosis angle (ÂngKIFint and ÂngKIFT12). Statistical analysis: Correlation to Pearson Moment-Product and t test (α<0.05). Results: the angular values (ÂngKIFint, ÂngKIFT12, ÂngKIX) were underestimated in relation to Cobb angle (p<0.05), correlating only to KIX angle and Cobb angle [r=0.698, p<0.001]. The linear values (KIFint, KIFT12, KIX) were similar ( p>0.05) among themselves, correlating only to KIX and Cobb angle [r=0.698, p<0.001] and KIX angle and KIX [r=1; p<0.001]. Conclusions: the KIX and KIX angle presented as an accurate method and valid to be used in the thoracic kyphosis assessment, although KIFint, KIFT12, KIFint angle and KIFT12 angle showed no correlation to the gold standard and not being indicated to assess the thoracic kyphosis in children and young people.

ABSTRACT The objective was to study the biochemical changes and dry matter content in lemon and mandarin hybrids under salt stress during rootstock formation. For this, a study was conducted in randomized complete block, using a 2 x 5 factorial scheme, with two salinity levels (0.3 and 4.0 dS m-1) applied in five citrus rootstock genotypes (1. TSKC x CTARG - 019; 2. LRF; 3. TSKC x (LCR x TR) - 040; 4. LCRSTC and 5. LVK), with three replicates and four plants per plot. At 90 days after sowing, saline treatments started to be applied and continued until 120 days after sowing, the moment in which the plants were collected for evaluation of biochemical characteristics and phytomass accumulation. The increase in water salinity negatively affected the biochemical components and dry matter accumulation of citrus genotypes. The genotypes TSKC x (LCR x TR) - 040, LCRSTC and LVK were the least affected by salt stress, standing out as the materials most tolerant to salinity.

Published: April 2017

ABSTRACT With the knowledge on the hygroscopic equilibrium of the baru (Dipteryx alata Vogel) fruit, the product can be adequately handled to maintain the moisture content at the levels recommended for safe storage. Thus, this paper aimed to determine the water desorption isotherms of baru fruits at temperatures of 20, 25, 30 and 35 °C, and water activity between 0.14 and 0.80, and obtain the values of isosteric heat of desorption as a function of the equilibrium moisture content of the product. The equilibrium moisture content was obtained using the static-gravimetric method. Modified Halsey was the best model recommended to represent the hygroscopicity of baru fruits. The recommended moisture contents for safe storage of baru fruits are not more than 19.9, 19.3, 18.6 and 18.0 (%, d.b.) for the respective temperatures of 20, 25, 30 and 35 °C. The integral isosteric heat of desorption increases as the water content decreases, leading to an increment in the energy required to remove water from the product.

Authors: Vieira Cristiane , Weber Oscarlina
Published: April 2017

RESUMO O ipê-amarelo (Tabebuia serratifolia) é uma espécie florestal com potencial madeireiro, porém, pouco utilizada em plantios florestais, devido à escassez de informações sobre sua produção tanto em viveiro quanto no campo. Diante disso, realizou-se experimento com o objetivo de verificar os efeitos da calagem no crescimento e na nutrição de mudas de T. serratifolia. O calcário foi misturado ao solo Latossolo Vermelho distrófico de textura franco-arenosa, em sacolas plásticas com capacidade para 2,5 kg. Os tratamentos foram dispostos em delineamento inteiramente casualizado, com cinco repetições: testemunha (26,5%); 60%; 70%; 80% e 100% de saturação por bases. Após 120 dias, avaliaram-se: altura, diâmetro de colo, relação altura e diâmetro, biomassa seca e índice de Dickson. As plantas secas foram submetidas às determinações dos teores de macronutrientes. Os melhores resultados para crescimento da T. serratifolia foram verificados no nível de 70%, principalmente porque N, K, Ca e Mg foram disponibilizados em concentrações adequadas, possibilitando o incremento.

RESUMO O objetivo do trabalho foi quantificar as perdas de nutrientes por lixiviação associadas ao uso de fertilizante mineral na produção de mudas de cedro australiano (Toona ciliata M. Roem var. australis) em diferentes substratos. O experimento foi realizado em casa de vegetação, em delineamento inteiramente casualizado com três repetições, com dois substratos (substrato comercial e composto de dejetos de suínos) e quatro doses de fertilizante mineral (0 kg; 3 kg; 6 kg e 9 kg m-3). No decorrer de 105 dias foram avaliadas as perdas de N, P e K por lixiviação e, no final desse período, quantificado o crescimento e a qualidade das mudas. O substrato comercial proporcionou menor perda de nutrientes por lixiviação e, quando associado ao fertilizante mineral, apresentou maior potencial de crescimento e de qualidade de mudas em comparação ao composto de dejetos de suínos.

RESUMO Objetivou-se avaliar o estoque e a retenção hídrica da serapilheira de 15 clones de espécies e de híbridos de Eucalyptus, aos três anos de idade. Foram coletadas amostras de 1 m2 da serapilheira acumulada por repetição. Cada amostra foi separada em frações galhos, folhas e material amorfo. As frações foram secas em estufa de ventilação forçada até peso constante e, posteriormente, foi determinada sua massa seca. A capacidade de retenção hídrica foi determinada com a técnica estabelecida em 1955 por Blow. Não houve diferenças significativas em relação ao estoque de serapilheira, contudo a média de acúmulo foi de 4,96 Mg.ha–1, com variação entre 3,34 e 4,96 Mg.ha–1. As frações contribuíram na seguinte ordem decrescente: folha > material amorfo > galhos. A capacidade de retenção hídrica (CRH) média foi de 249,58%, tendo havido valor significativamente menor para os clones S-0208, S-0303 e S-0412. A frações contribuíram na seguinte ordem decrescente: material amorfo > folhas > galhos. Apesar da diferença significativa entre a CRH das frações, todas contribuem para a retenção hídrica total da serapilheira.
