Published: March 2021

Demonstration plots (demo plots) have been used as participatory research methods to conduct Climate Field Schools (CFS) with farmers from May to October 2018. CFS aimed at improving the adaptive capacities of the farmers and obtaining appropriate technologies to be adopted in the two villages of Ciganjeng and Rawaapu. The demo plots were set up with a different treatment of organic manure (T1 = 10 ton ha−1 of cattle compost; T2 = 10 ton ha−1 of cattle compost + 10 ton ha−1 of Azolla pinnata; and T3 = 10 ton ha−1 of cattle compost + 2 ton ha−1 of Sesbania rostrata) and different rice varieties. The farmers were fully responsible for the monitoring of the parameters (e.g., plant height, number of tillers, and grain yield). The demo plots results revealed that the application of organic manure T2 has increased the soil C and N content by 64.6 and 40.00%, respectively, and rice yield by 27.8% compared to neighboring plots using inorganic fertilizers. The Mendawak variety at both CFS locations showed better performance compared to the other varieties. Moreover, the capacity of the research farmers involved in the CFS has been increased by 52.74% with a gain factor of 0.42 in Ciganjeng and 41.23% with a gain factor of 0.39 in Rawaapu moderately based on pretest and posttest results. It is concluded from the research process that farmers who built up their capacity on on-farm show a high level of confidence and can convey comprehensive information to other farmers.

Coyne, JOC, Coutts, AJ, Newton, RU, and Haff, GG. The influence of mental fatigue on sessional ratings of perceived exertion in elite open and closed skill sports athletes. J Strength Cond Res 35(4): 963–969, 2021—The main purpose of this investigation was to examine influence of mental fatigue on sessional ratings of perceived exertion (sRPE) over a training week in elite athletes in open skill (OS, i.e., more unpredictable and externally paced sports) and closed skill (CS, i.e., more predictable and internally paced) sports. Visual analogue scales for mental fatigue, sRPE (CR-10 scale), and training duration were collected from an OS group (n = 27) of basketball and volleyball athletes and a CS group (n = 28) of weightlifting and track and field athletes during a typical training week 5 months before the 2016 Olympic Games. These variables were then examined using repeated measure correlations and linear mixed models with the level of significance set for the study at p < 0.05. There was a small significant correlation between mental fatigue and sRPE in the OS group (r = 0.23, p < 0.01), but not in the CS group (r = −0.07, p = 0.38). Mental fatigue had trivial influence on sRPE during individual sessions, but had a moderate effect on total sRPE over a week (p < 0.001, f
2 = 0.265) when accounting for type of sport, training duration, and injury/illness burden. It seems mental fatigue may not significantly influence sRPE in individual training sessions, but may potentially have a cumulative effect that may affect the sRPE over a training week. This suggests monitoring mental fatigue independently of other training load (TL) measures may be worthwhile for strength and conditioning specialists and sports coaches to manage their athletes and researchers conducting studies into TL and performance.
Respiratory sinus arrhythmia predicts perceived therapy process of a group-based acceptance and commitment therapy intervention

Published: March 2021

Engagement in psychotherapy is partially contingent on present-moment focus, mindfulness, and emotion regulation skills. These skills can be linked to parasympathetic functioning with theoretical explanations provided by polyvagal and neurovisceral integration theories. The specific aims of this project were to evaluate relationships between a measure of parasympathetic functioning (respiratory sinus arrythmia [RSA]) and measures of client reports of engagement in an experiential and emotionally evocative group-based intervention. Twenty-one community residents received group-based acceptance and commitment therapy (ACT) for work stress. RSA was measured 1 week before the intervention. Client ratings of relationship support, task focus, and hindering experiences were assessed after each session. Results indicated that clients perceived the ACT intervention to be supportive, task-focused, and without significant therapy-hindering experiences. Higher levels of RSA were significantly associated with higher levels of relationship support. These results support predictions derived from the polyvagal and neurovisceral integration theories.

Published: March 2021

Adults with borderline personality disorder (BPD) report greater affective lability, impulsivity, and aggression compared to same-age peers, but no studies have examined whether these findings are replicable among adolescents with BPD and their peers, or whether adolescents and adults with BPD report symptoms of comparable severity. One hundred and one adolescent (age 13–17) BPD inpatients and 60 age-matched, psychiatrically healthy adolescents completed self-report measures for affective lability, impulsivity, and aggression. Comparison samples included 29 and 41 adult outpatients with BPD and 127 community adults with BPD. Adolescents with BPD reported greater severity of all symptoms except nonplanning impulsiveness compared to peers. They reported similar symptom severity to adults but reported less severe verbal aggression and anger. Adolescents with BPD are distinguishable from typically developing adolescents on self-reported, dimensional affective and behavioral symptom measures, and may experience these symptoms at comparable severity to adult counterparts.
Nonsuicidal Self-Injury in Early Adolescence as a Predictor of Borderline Personality Disorder in Early Adulthood

Published: March 2021

Borderline personality disorder (BPD) typically has an onset in adolescence. Nonsuicidal self-injury (NSSI) could be associated with its subsequent development. The aim of this study was to examine whether NSSI among adolescents in the community is associated with a risk for BPD in emerging adulthood. Sixty-nine adolescents (11-13 years old) with a history of NSSI and 61 matched controls were assessed for NSSI and then reassessed between ages 18 to 20 years. Findings showed that continuation of NSSI over time was associated with higher ratings of BPD symptomatology and greater impairment in psychosocial functioning. Both of these relations were mediated by deficits in emotion regulation. These results suggest that adolescents who engage in NSSI may need to be assessed for problems regulating emotions and to be provided with early interventions to help prevent continuation of NSSI.

Published: March 2021

Neural dynamics in response to affective stimuli are linked to momentary emotional experiences. The amygdala, in particular, is involved in subjective emotional experience and assigning value to neutral stimuli. Because amygdala activity persistence following aversive events varies across individuals, some may evaluate subsequent neutral stimuli more negatively than others. This may lead to more frequent and long-lasting momentary emotional experiences, which may also be linked to self-evaluative measures of psychological well-being (PWB). Despite extant links between daily affect and PWB, few studies have directly explored the links between amygdala persistence, daily affective experience, and PWB. To that end, we examined data from 52 human adults (67% female) in the Midlife in the United States study who completed measures of PWB, daily affect, and functional MRI (fMRI). During fMRI, participants viewed affective images followed by a neutral facial expression, permitting quantification of individual differences in the similarity of amygdala representations of affective stimuli and neutral facial expressions that follow. Using representational similarity analysis, neural persistence following aversive stimuli was operationalized as similarity between the amygdala activation patterns while encoding negative images and the neutral facial expressions shown afterward. Individuals demonstrating less persistent activation patterns in the left amygdala to aversive stimuli reported more positive and less negative affect in daily life. Further, daily positive affect served as an indirect link between left amygdala persistence and PWB. These results clarify important connections between individual differences in brain function, daily experiences of affect, and well-being.

SIGNIFICANCE STATEMENTAt the intersection of affective neuroscience and psychology, researchers have aimed to understand how individual differences in the neural processing of affective events map onto to real-world emotional experiences and evaluations of well-being. Using a longitudinal dataset from 52 adults in the Midlife in the United States (MIDUS) study, we provide an integrative model of affective functioning: less amygdala persistence following negative images predicts greater positive affect (PA) in daily life, which in turn predicts greater psychological well-being (PWB) seven years later. Thus, day-to-day experiences of PA comprise a promising intermediate step that links individual differences in neural dynamics to complex judgements of PWB.
Anterior Cingulate Cortex Lesions Abolish Budget Effects on Effort-Based Decision-Making in Rat Consumers

Published: March 2021

Demand theory can be applied to analyze how animal consumers change their selection of commodities in response to changes in commodity prices, given budget constraints. Previous work has shown that demand elasticities in rats differed between uncompensated budget conditions in which the budget available to be spent on the commodities (e.g., the finite number of discrete operants to “purchase” rewards in two-alternative fixed-ratio schedules) was kept constant, and compensated budget conditions in which the budget was adjusted so that consumers could potentially continue to obtain the original reward bundles. Here, we hypothesized that rat anterior cingulate cortex (ACC) was necessary to produce this budget effect on demand elasticities. We applied excitotoxic or sham lesions to ACC in rats performing an effort task in which the prices of liquid vanilla or chocolate rewards (the effort required to obtain rewards) and the budget (the total number of operants) was manipulated. When reward prices changed, and the budget was compensated, all rats adjusted their demand for chocolate and vanilla accordingly. In sham-lesioned rats, changes in demand were even more pronounced when the budget was not compensated for the price changes. By contrast, ACC-lesioned animals did not show this additional budget effect. An in-depth comparison of the rats' choice patterns showed that, unlike sham rats, ACC-lesioned animals failed to maximize session-bundle utility after price/budget changes, revealing deficits in higher-order choice-strategy adaptations. Our results suggest a novel role of ACC in considering purchasing power during complex cost-benefit value computations.

SIGNIFICANCE STATEMENTAnterior cingulate cortex (ACC) is important for allocating effort in cost-benefit calculations in animals and humans. Economic theory prescribes that the value of the costs in cost-benefit analyses not only depends on the net nominal costs required to purchase a reward, but also on the available budget resources, i.e., on the budget's “purchasing value.” We asked whether ACC, a region implicated in effort-based decision-making and reward comparisons, is required for computing the value of effort relative to a budget constraint. Applying demand theory to describe rat choices in a rodent effort allocation task with varying effort prices and budgets, we show that ACC integrity was necessary for computing purchasing power, a core variable in economic choice theory.
Effect of layering pattern and fiber hybridization on viscoelastic properties of PALF/COIR hybrid epoxy composites
Authors: Mittal Mohit , Chaudhary Rajiv
Published: March 2021

To design and develop a hybrid biocomposite material for structural applications, it becomes necessary to determine the optimum fibers layering pattern. Therefore, in this research work, the different layered hybrid biocomposite boards i.e. bilayer pineapple/coir (P/C), trilayer (PCP, CPC), and intimately mixed (IM) were developed and characterized for viscoelastic properties. The composites were made by hand lay-up method, keeping the volume ratio of PALF and COIR 1:1 and the total fiber volume fraction is 0.40 volume of composite. Dynamic mechanical thermal analysis test was employed to characterize the viscoelastic behavior in terms of storage modulus, loss modulus, loss damping factor, and the glass transition temperature. Amongst all the different layered hybrid composites, the trilayer CPC has lowest value (0.635) of effectiveness coefficient with highest stiffness and activation energy (40.54 kJ/mole). It confirms the better fiber-matrix interaction at the interfacial region. The glass transition temperature of CF-EP and PF-EP was increased by 8.74% and 13.15% respectively by the synergistic hybridization of cellulosic fibers. The PCP layered composite possesses lowest value of phase transition energy (9.17 kJ/mole) and this was because of the poor fiber-matrix interfacial adhesion.

El objetivo de este estudio fue determinar las características morfológicas de 9 árbitros centrales y 13 árbitros asistentes de fútbol de la segunda división de la liga MX en México. Se les tomaron mediciones antropométricas y evaluaciones con la Absorciometría dual de rayos X (DEXA) para obtener la masa grasa y la masa libre de grasa. En la proporcionalidad se utilizó en método del somatotipo para poder obtener el biotipo. Los árbitros centrales obtuvieron menor porcentaje graso (antropometría y DEXA) que los árbitros asistentes, presentándose en estos últimos un somatotipo con mayor robustez musculo esquelética. A pesar de que los árbitros centrales obtuvieron un estado corporal con menos grasa que los asistentes, por el simple hecho de que las exigencias físicas en un partido de fútbol son doblemente mayores, no se encontraron diferencias acordes a las características que muestran los árbitros de elite.

Published: March 2021

The aim of this study was to evaluate the efficacy of the Odontogenic Keratocyst treatment through enucleation and cryotherapy with liquid nitrogen in a lesion that had previously been biopsied and also to compare the microscopic characteristic of the enucleated lesion to the biopsy microscopy. Enucleation was performed in a 27-year-old female patient with previously diagnosis by initial biopsy. The lesion extended from left mandibular body region to the ramus ipsilateral. The use of this technique proved to be an effective treatment. It is believed that the initial biopsies allowed a decrease in the size of the lesion and increase the thickness of the fibrous capsule, which prevent the rupture of the keratocyst capsule.
Structural transformations of the EU industrial sector
Authors:   Department of International Economics, Kyiv Vadym Hetman National University of Economics, Skorik Ksenia
Published: March 2021

The issue of industrial policy and industrial problems is one of the most controversial in the European academic community. Even today, we see a lack of theoretical basis for decision-making on industrial policy issues. The main purpose of the publication is to assess the contribution of industry to the socio-economic development of the EU and its member states, as well as to the dynamic structural changes that took place during 2000-2019. To achieve the article's goal, the author uses such indicators as the share of the industrial sector in the generation of gross value added, employment, labor productivity, and exports/imports. The article reveals a general trend to increase in the share of the services sector in the generation of gross value added for the EU-28 and to decrease in the share of the industrial sector. It is established that industry remains an important sector for the EU economy, and for the EU-28, it provides almost 20% of gross value added and more than 70% of total exports, and accounts for about 15% of the employed population. For each of the EU countries, the socio-economic contribution of industry is different - for Central and Eastern Europe, it is more important in the generation of gross value added and employment than for the EU founder countries of the euro area (the EU-15 group). It is found that labor productivity in the EU-15 is higher than in other countries. Growing labor productivity is typical for Denmark, the Netherlands, Ireland, Sweden, and Great Britain, while lower productivity - for such CEE countries as Bulgaria, Romania, Lithuania, and Latvia. At the same time, growth rates of all industrial indicators in the latter countries is much higher than in the EU-15. The author considers the new EU industrial policy and various problems of the industrial sector in the EU. The study was carried out on the statistical basis of the European Commission using the methodology of Polish scientists of the Warsaw School of Economics to study the new industrial policy (Krzysztof Falkowski, Adam A. Ambroziak 2015).

DIE EMIGRATION ALS STRUKTURPROBLEM DER UNGARISCHEN LITERATURGESCHICHTE
Authors: SCHEIN GÁBOR
Published: March 2021

Die bis heute konsensuale Auﬀassung der Nationalliteratur in Ungarn wird durch die sprachliche Homogenität bestimmt. Elemente, die eine Provokation für die Homogenität bedeuten, werden entweder in bipolaren Gegensätzen eingeordnet, und dadurch vom Zentrum ferngehalten, oder sie werden vertuscht und ausgeschlossen, wie man es im Falle der auf Fremdsprachen geschriebenen Werke der ungarischen Literatur erfahren kann. Innerhalb der Struktur der ungarischen Nationalliteratur verdient die Emigration eine besondere Aufmerksamkeit, weil sie es notwendig macht, dass wir über die ungarische Literatur in Überlappungen mit anderen Literaturen sprechen. Wenn wir über Überlappungen sprechen, müssen wir in die Problematik auch die Theorie des Transnationalismus mit einbeziehen. In der ungarischen Fachliteratur wird diese Theorie auf die Fälle der geographischen und politischen Grenzübergänge beschränkt, die die mentale Einprägung der Grenzen als Reflexionsobjekte immer voraussetzen. Die Grenzphänomene verbinden sich mit den Vorstellungen der Diﬀerenzen, dadurch bleiben sie die Kulminationspunkte der Macht und der Kontrolle. Die Theorie des Transnationalismus kann aber auch dabei helfen, dass die Vorstellungen der Nation aus dem Bereich der homogenisierenden Aspirationen der Macht entfernt werden, damit die Heterogenität des von der Macht territorisierten Raumes, in diesem Fall des literarischen Raumes klar gezeigt werden kann. Die literarischen Räume von Ost-Mittel-Europa hatten schon immer eine mehrsprachige und polikulturelle Ausdehnung, erst nach dem ersten Weltkrieg wurden die Diﬀerenzen im Interresse der Homogenisierung der Machtbereichen als Gegensätze instrumentalisiert. Das Aufgreifen des Problems der Emigration macht es möglich, diese räumliche Struktur neuzugestalten, weil die Emigraton nicht einmal als eine periphere Erscheinung am Konzept der ungarischen Nationalliteratur teil hat. Die Emigration kann nicht zuletzt auch die Kräfte des inneren Zusammenhalts im Raum der Nationalliteratur verstärken, denn sie lässt das Aufheben der lokalen Kontexte und die Beseitigung der Diﬀerenzen nicht zu, die als Voraussetzungen von Ähnlichkeiten immer ins Spiel gebracht werden. Worüber ich hier spreche, ist eine Hypothese für eine mögliche Selbstkorrektion. Auch diese Hypothese muss ihre Begriﬀlichkeit der Kritik aussetzen. Wenn aber die Raumstruktur der ungarischen Nationalliteratur als Modell einmal neugestaltet wird, wird die Verwendung des Begriﬀs der Emigration ihre Gültigkeit verlieren.

Published: March 2021

Previously isolated Pseudomonas lundensis CP-P-5 had antagonistic activity against Salmonella Hartford, Yersinia enterocolitica, and Escherichia coli. In this study, determination of its antagonistic mechanism and potential field of application in food industry was aimed. Using cellophane-test and microcultures of the test strain's cell-free supernatant mixed with the pathogens, our results showed that cells of P. lundensis CP-P-5 and its concentrated cell-free supernatants were effective against the foodborne bacteria, and the supernatants contained more than one compound responsible for inhibitory activity. Searching for the antagonistic compound, NaOH, protease, and heat treatments were done to the supernatants, and proteolytic activity and siderophore production were also tested using the antagonistic strain. Our results support the potential applicability of P. lundensis CP-P-5 as a bioprotective agent against foodborne pathogens in food processing environments.

Published: March 2021

Upon cartilage damage its natural recovery takes a long time. This is due to several reasons: the absence of blood vessels and low metabolic activity. In this regard, it is relevant to study the mechanism of operation of all components involved in the remodeling of cartilage tissue. For this purpose, protein insulin-like growth factor 1 (IGF-1) was taken as an object of research, since one of its main functions is regulation of cell proliferation, which is closely related to the process of cartilage tissue repair. It is known that in recent years, scientific studies have been conducted on the effect of IGF-1 on the remodeling of cartilage tissues, but in combination with other substances that stimulate more active cell regeneration. This review presents the features of the functional properties and protein structure and its main influence on chondrocyte proliferation for further development of accelerated and effective methods of IGF-1 action on cell growth and repair. The phylogenetic analysis of IGF-1 showed the most related organism for human IGF-1 and structural differences of its protein from human, which are inextricably linked with the functional characteristics of each of the organisms. The results of phylogenetic analysis in the future will identify the object for laboratory research in this question and the search for optimal ways to accelerate the process of remodeling of cartilage joints.

Assessment of the Balanced Functioning of Hierarchical Socio-Economic Systems
Authors:   Financial University under the Government of the Russian Federation (Tula Branch), Zhukov R. A.
Published: March 2021

Balance is one of the properties of the system, and the problems associated with the assessment of balance, the choice of indicators, methods and tools that allow you to make informed management decisions in this area in the future are still open. The aim of the study is to develop and test a methodology for assessing the balance of the functioning of hierarchical socio-economic systems on the basis of the case of the regions of the Central Federal District of Russia. The hypothesis is that the proposed methodology can be effectively applied to study the balance of complex systems along with existing methods in the framework of a new theory of economic systems. The method consists in the formation of special indicators – the coefficient of harmony and the adjusted index of system balance, which allow us to assess the degree of balance of subsystems within the accepted space-time classification. The first of them takes into account the spread of generalized (integral) performance indicators that characterize the object, environment, process and project subsystems. The second one is the intensity of the relationships between them. The integral indicator is calculated by means of a special procedure for convolution of partial results (actual and normative). The norm is determined by a model of the relationship between performance and significant factor characteristics. The peculiarity of the proposed method is the possibility of its use at different levels of management. It also provides a reasonable comparison of the results of the functioning of various subsystems and elements by eliminating the influence of units of measurement and the scale effect; the mutual influence of the considered elements and subsystems is taken into account; the specific conditions of their operation are taken into account. The case of the regions of the Central Federal District is used to carry out a comparative analysis of the results of assessing the balance of subsystems using the volume of gross domestic product by region by type of economic activity for 2007-2018,. The conclusion is made about the possibility of using, along with the index of system balance, the coefficient of harmony.

PURPOSE: The study aimed to examine whether handgrip strength (HGS) expressed as absolute or relative to body weight is associated with fasting glucose (FG), hemoglobin A1c (HbA1c) and the prevalence of diabetes mellitus (DM) in different age categories.METHODS:A total of 28,129 adults from the Korea National Health and Nutrition Examination Survey of 2014-2018 was analyzed. To examine the relationship between HGS and variables related to DM, participants were categorized into three groups according to their HGS (Tertile). Then, participants were further categorized into six groups according to their age. One-way ANOVA and logistic regression analyses were performed.RESULTS: Compared with participants in the upper tertile of absolute handgrip strength (AHGS), those in the lower tertile were older, shorter and heavier and also had higher FG and HbA1c. When age was adjusted, the prevalence of DM was 1.19 times (95% CI: 1.03-1.38) higher among men in the lowest tertile of AHGS. On the other hand, compared with participants in the highest tertile of relative handgrip strength (RHGS), those in the lowest tertile had 2.10 times (95% CI: 1.87-2.41) and 2.42 times (95% CI: 2.08-2.81) higher prevalence of DM in men and women, respectively. When the associations were examined according to age subcategories, significant associations between AHGS and the prevalence of DM were seen only in men in their 50s and 60s, but not seen in women in all age groups, with the exception of the 60s. However, significant associations between RHGS and the prevalence of DM were seen in all age subcategories.CONCLUSIONS:We concluded that the association between HGS and the prevalence of DM was dependent on age and RHGS is a stonger measure than AHGS.

PURPOSE: Foot reflexology has become popular for sustainable health management because it is free from side effects, easy to learn and perform. The purpose of this study was to investigate the effects of foot reflexology on the physical symptoms of cancer patients.METHODS: The systematic review and meta-analysis was conducted by following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Data were pooled using fixed- or random-effects models. Pain, sleep, fatigue, and nausea and vomiting were analyzed for the main effects. Eighteen studies were included, representing 931 participants.RESULTS: Foot reflexology was effective in alleviating pain (d=-1.05; 95% CI: -1.52, -0.59), promoting sleep (d=1.15; 95% CI: 0.45, 1.85), and relieving fatigue (d=-1.46; 95% CI: -1.79, -1.14), but it was not significantly effective in reducing nausea and vomiting (d=-0.53; 95% CI: -1.29, 0.22).CONCLUSIONS: Based on these findings, there is clear evidence that foot reflexology has significant positive effects on the physical symptoms of cancer patients. Further study is needed, however, to perform subgroup analysis using the frequency of sessions as predictors.

Abstract ‘Green Dwarf’ coconut is a fruit of great economic interest, since all its components are used, in addition to water, its main component. It is a culture of humid tropics, widely produced in northeastern Brazil, being an important income source for the region. The phenology study of this type of fruit is extremely important, but there are few studies in literature. Regression models, especially nonlinear growth models, can be of great value to understand how fruit growth behaves. The scarcity of works of this nature may be linked to some difficulties in estimating parameters of nonlinear models, such as assigning initial values to the itterative process. Overcoming this difficulty, for regression analysis, linear or not, several steps need to be respected to ensure the validity of information. Much information can be extracted from nonlinear growth models, such as the asynotic value, growth rate and critical points (maximum acceleration point, inflection point, maximum deceleration point and asynotic deceleration point). The aim of this work was to describe the stages of nonlinear regression analysis and to estimate the critical points of ‘Green Dwarf ’ coconut growth curves. After initial adjustments, the only unmet assumption was independence, adding a first order autoregressive term. Again, models were adjusted and all parameters were significant, with both models, Gompertz and Logistic, adjusting well to data, with slight advantage for the Logistic model with better adjustment quality criteria values, with maximum expected LED and LEDKP values of 21.4037 cm and 21.5478 cm, respectively. The x and y axis of critical points were estimated, with values that can help producers to make more objective decisions about the appropriate time to harvest coconut fruits, considering the most diverse uses of this type of fruit.

Abstract Sete-capote tree, a neglected species, has great ecological, cultural and potential economic importance, however, studies for this and other native species of the Myrtaceae family are still scarce. The objective of this study was to elucidate aspects of pollen germination and viability of this specie. For the experiment, pollen from flowers in pre and post anthesis was used, which was dehydrated in a chamber containing silica, for different periods. For germination tests, different concentrations of sucrose, boric acid and calcium nitrate were used. After obtaining germination results above 80%, the pollen grains were stored in refrigerator (5 °C), freezer (-17 °C), liquid nitrogen (-147 °C) and natural environment (± 25 °C), evaluating monthly the germination, until total loss of viability. For germination, it was recommend using pollen from flowers in post-anthesis, dehydrated for 24 hours in a silica chamber. The culture medium should contain 12% sucrose (C12H22O11), 10% boric acid (H3BO3) and 20% calcium nitrate (Ca(NO3)2) to obtain high germinative percentages. In addition, pollen presents orthodox behavior and when stored in liquid nitrogen, remains viable for 30 days.

ABSTRACT The objective of this study was to evaluate the effect of artificial defoliation on vegetative and productive stages of cowpea inoculated with diazotrophic bacteria, in two experiments. The first experiment was performed in a greenhouse with 5 × 5 factorial (five defoliation percentages and five N sources), with four repetitions. N sources consisted of bacterial inoculation with strains INPA 03-11B, UFLA 03-84, UFRB FA34C2-2, and two control treatments: i - with N fertilization and ii - blank control, without N fertilization and without inoculation. The second experiment was performed in the field, in a 3 × 5 factorial scheme, with three repetitions. Treatments consisted of three N sources: with N fertilization, with bacterial strain INPA 03-11B that was selected in the first experiment, and five percentages of artificial defoliation. Defoliation percentages for both experiments were 0, 25, 50, 75, and 100%. Artificial defoliation during the vegetative stage caused reduction in the dry mass of bacterial nodules. Inoculation increased plant tolerance to defoliation and enhanced grain nutrient concentration (N and P). Inoculation with the strain INPA 03-11B allowed cowpea plants to tolerate 50% defoliation in the vegetative stage. The mean productivity of cowpea was reduced under > 50% defoliation during the productive stage; therefore, control of defoliating pests until the productive stage is not necessary under field conditions.

ABSTRACT This study aimed to determine drying curves of land saffron (Curcuma longa L.) rhizomes at different temperatures and ventilation conditions to adjust non-linear regression models, and to calculate effective diffusion coefficients and activation energies. Saffron rhizomes were randomly collected in natura with a hoe from the soil in Rio Verde, Goiás, Brazil. They were subsequently sized, sanitized, and sliced into 2.63 ± 0.1 mm thick sections. Rhizomes were dried in an oven with forced air ventilation at 45, 55, 65 and 75 °C for 18, 14, 10 and 9 hours, respectively. As the temperature increased, drying time was reduced. Consequently, moisture content also decreased, facilitating the drying process by decreasing the energy required to remove water molecules. Among the analyzed models, the Midilli model was best adjusted to the data under different drying air conditions. Effective diffusion coefficients (D) were 9.17 × 10-11, 13.33 × 10-11, 20.09 × 10-11, and 35.89 × 10-11 m2 s-1 at 45, 55, 65 and 75 °C, respectively, increasing with higher temperatures. Activation energy for liquid diffusion during drying was 21.186 kJ mol-1.

ABSTRACT Characterization of cocoa clones produced in the semiarid region is necessary to enlarge the database about these implanted clones and thus enhance the quality of their by-products. Therefore, this study aims to evaluate physical, chemical, and physicochemical characteristics of the CCN 51, CEPEC 2004, CEPEC 2005, and PS 1319 clones, produced in the region of Vale do Jaguaribe in the state of Ceará (Brazil), and to suggest food processes or products for them. The clones were evaluated according to their physical traits (total fruit mass, rind, pulp, seeds, and placenta and pulp with seeds), fruit transverse diameter (FTD), fruit longitudinal diameter (FLD), the ratio FTD/FLD; rind external thickness (ERT), rind internal thickness (IRT), the ratio ERT/IRT, number of seeds, seed thickness, seed transverse diameter (STD), seed longitudinal diameter (SLD), and the ratio STD/SLD, yield, pulp color, chemical traits (humidity, lipids, proteins, ashes, crude fiber, and carbohydrates), and physicochemical traits (titratable acidity, pH, soluble solids, and reducing sugars) were evaluated. The CCN 51 and CEPEC 2005 clones are the most suitable for the process of cocoa fermentation. For desserts, jams, pulp, and nibs for fat-restricted diets, the most suitable clones are CCN 51, CEPEC 2005, PS 1319 and CEPEC 2004, respectively.
