Posttraumatic Stress Disorder Symptoms and Criminal Behavior in U.S. Army Populations: The Mediating Role of Psychopathy and Suicidal Ideation
Authors: Traynham Stephanie , Kelley Amanda M. , Long Christopher P. , Britt Thomas W.
Published: February 2019

Whereas past research has demonstrated the relationship between posttraumatic stress disorder (PTSD) and criminal behavior, the present study examines the underlying mechanisms driving this association. The primary objective was to determine the role of psychopathy and suicidal ideation as mediating factors in the relationship between military PTSD symptoms and criminal behavior (defined as incarceration status). A correlational study using archival data from the U.S. Disciplinary Barracks (USDB) and a control population of U.S. Army soldiers was conducted. The USDB provided data from 310 incarcerated male U.S. Army soldiers. Data were also collected from 310 nonincarcerated, male U.S. Army soldiers in the greater Fort Rucker, Alabama area. Data validity checks eliminated some cases, thus yielding a final dataset of 246 USDB and 252 control participants. The results suggested partial mediation, in that PTSD symptoms had a direct effect on incarceration status, and significant indirect effects through suicidal ideation and psychopathy while controlling for intelligence and warmth. In furnishing evidence of how psychopathy and suicidal ideation mediate the relationship between PTSD and incarceration status in military personnel, this research highlights specific internalization and externalization mechanisms that may increase the tendencies of people with greater PTSD symptoms to engage in criminal behaviors. By adding to the small amount of prior research on why PTSD sometimes leads people to engage in criminal behaviors, our research provides specific, observable symptoms that clinicians may use to identify, treat, and possibly ameliorate facets of PTSD that can lead affected people to engage in criminal behaviors.

The Impact of Organizational Change on Government Civil Servants’ Behavioral Responses in China
Authors: Bin Shan
Published: February 2019

With the globalization and the development of scientific technology, competition pressure is more and more in all kinds of organization. Thus, organizational change is becoming the norm, which inevitably lead to the uncertainty of employment relationship, particularly, on employees’ serious of behaviours. These effects have become the vital factors in the organization achieving its organizational goals, and have become an important factor in determining successful organizational change. However, the relevant studies are based predominately on Western theories and models, rather than Chinese cultural background, especially within a public sector context such as the government. By selecting more than 500 Chinese civil servants for the questionnaire, this study is going to measure the dimension of organizational change in Chinese government, and its impact on Chinese civil servants’ behavioural responses. The results show that the impact of different organizational change on Chinese civil servants’ behavioural responses (Exit, Voice, Loyalty, Neglect) is different.

Vigilance Behaviour of Wild Herbivores when Foraging With or Without Livestock
Authors: Baltazary Angelamercy , Roskaft Eivin , Treydte Anna C.
Published: February 2019

In African savannas, and many other rangelands around the world, wildlife presently find themselves interacting with livestock. Many studies have been conducted on vigilance behaviour in response to presence of predators on foraging grounds, but few scientists have included the presence of livestock and how this affects vigilance when foraging together with wild herbivores. As Ngorongoro Conservation Area (NCA) is an important example of wildlife grazing together with livestock, this phenomenon must be understood to achieve a sustainable land use management plan, particularly in Ngorongoro Conservation Area and in other protected areas. Behavioral observations of wildlife and livestock species were conducted from a vehicle driving along transects within NCA. Once a group was sighted the vehicle was stopped and sighting information recorded. Four species of wild herbivores including plains zebra (Equus burchelli), Thomson’s gazelle (Gazella thomsonii), Grant’s gazelle (Gazella granti) and Wildebeest (Connochaetes taurinus) were studied together with the following livestock species including cattle (Bos taurus), goats (Capra aegagrus hircus) and sheep (Ovis aries), in different seasons. 158 groups were recorded. In dry season 47 non –mixed groups (without livestock) and 30 mixed groups (with livestock) were recorded, while, during wet season 49 non -mixed groups and 32 mixed groups were recorded. Behavior was classified as feeding, grooming, laying down, ruminating, grooming, moving, and looking with head up (vigilance) with the use of the focal animal sampling method. Wildlife decreased their foraging time while they increased vigilance behavior when livestock were present; however, more studies are still for a wider conclusion.
The Effects of Corporate Financing Decisions on Firm Value in Bursa Malaysia

Published: February 2019

The primary objective of shareholders and financial managers is generally stated to be the maximization of shareholders’ wealth by increasing the firm value. This research was undertaken to investigate the effect of corporate financing decisions on firm value       . The research has been carried out using the panel data procedure for a sample of 256 firms from 9 sectors listed on Bursa Malaysia during the period 2000-2015. The study uses Tobin’s Q representing firm value for the dependent variable. The corporate financing was measured by leverage (short-term debt to total assets, long-term debt to total assets, total debt to total assets and total debt to total equity) and debt maturity (long-term debt to total debt). Short-term debt to total assets and long-term debt to total assets has a positive significant relationship to firm value. This finding is consistent with the view that leverage and dividends mitigate agency costs of free cash flow problems, therefore, increasing firm value. Total debt to total assets affects firm value negatively. This proves that although there are benefits of debts, there is also the cost of debts. The cost of debt financing arises from the increase in the probability of bankruptcy. Firm value does not depend on the length of debt maturity.
The Impact of Perceived Social Media Marketing Activities: An Empirical Study in Saudi Context
Authors: Khan Maha M.
Published: February 2019

Purpose – The purpose is to investigate the impact of social media marketing activities in the context of Saudi consumers of social media. A research model is developed in this study to examine the relationships.

Design/methodology/approach – This research is quantitative and uses the probability sampling technique, simple random sampling. Data is collected through a questionnaire in a survey of 241 Saudi social media users. Structural equation modeling (SEM) with PLS 3 was used with SPSS 22.0 for statistical data analysis. Chi–square and overall model fit indices further confirm the structural model fit.

Findings – The results indicate that social media marketing activities significantly influence brand loyalty, purchase intentions, value consciousness and brand consciousness; brand loyalty has a significant statistical impact on eWOM; eWOM influences purchase intention significantly; brand consciousness does not mediate the relationship between perceived social media marketing and brand loyalty, while value consciousness mediates this relationship.

Research limitations/ future research – The research is limited to Saudi social media users and this limits the results from being generalized. Future research must be conducted in other countries. Moreover, limited research is conducted with these variables in previous studies.

Originality/value – This article is pioneering in that it investigates the effects of social media marketing in the context of Saudi consumers, a topic of relevance for both marketers and scholars in the era of social media. It provides empirical evidence and valuable insights through a proposed model.

Effects of Sedimentation on Small Reservoirs in the Mushibemba Catchment, Mkushi Farm Block, Central Zambia
Authors: Mphande Goodfellow , Sichingabula Henry M.
Published: February 2019

Sedimentation is one of the problems that affects the storage capacity of most small reservoirs, and if not addressed on time it may lead to the dams being filled up with sediment. The aim of this study was to assess the effects of sedimentation on the storage capacity losses of Moffat dam and GRZ Weir located in the Mushibemba Catchment of Mkushi Farm Block, Central Zambia. The method used to understand reservoir storage capacity loss was bathymetry survey using the hydrographic survey boat (RC-S2) which consists of an echo sounder and a Differential GPS. Information on the initial storage capacity of the two reservoirs was obtained from the Water Resources Management Authority (WARMA). The analysis of the data revealed that the measured volumes of Moffat dam and GRZ Weir were 1,180,462 m3 and 197,218 m3, respectively. The estimated storage capacity losses for Moffat reservoir was found to be 223,789 m³ and 53,312 m3 for the GRZ Weir.  The estimated rates of sedimentation loss were found to be 13,986.81 m3 yr-1 (Moffat reservoir), with a lifespan of 84 years, and 1,480.89 m3 yr-1 (GRZ Weir) with a lifespan of 133 years. The source of the accumulated sediment was mainly attributed to originate from the cleared commercial agricultural land which predominantly consists of clayey to loamy soils. This also accounted for the high turbidity of the reservoir water. This situation therefore calls for periodic dredging of the deposited sediment to increase reservoir storage capacity.

Adenoid cystic carcinoma (ACC) is a rare neoplasm of secretory epithelium that most commonly occurs in the fifth and sixth decades of life. It is characterized by high recurrence rates and poor response to chemotherapy. In the orbit, ACC usually presents as a lacrimal gland mass. We describe the rare case of a 70-year-old woman who presented with pain during mastication and bilateral facial numbness in the cranial nerve V2 distribution. She was found to have adenoid cystic carcinoma involving the orbits bilaterally without lacrimal gland involvement and without a clear primary tumor. Imaging suggested that the tumor arose from the soft palate by extension along cranial nerves V2 and V3. The patient was treated with radiation therapy with some degree of radiographic improvement 27 months after diagnosis. This case emphasizes the importance of considering adenoid cystic carcinoma when evaluating orbital tumors sparing the lacrimal gland. We also suggest the possibility of an oropharyngeal source with anterograde intracranial extension in cases of putative primary orbital ACC without lacrimal gland involvement.

The Sisal (Agave sisalana Perrine) is a crop very important for the semi-arid region of Brazil, constituting an important source of income in regions that lack options that help in their development. However, studies regarding the development of this crop are scarce, reflecting on the low technology use and ancient practices used in the production systems. Theobject of this studywas to evaluated the initial growth development of plants of Sisal (Agave sisalana Perrine) under different sources of chemical and organic fertilization and presence and absence of intercropping with common bean (Phaseolus vulgaris), in the city of Areia, Paraíba. The experiment was carried out in a randomized complete block design (RCBD), in a 2x3 factorial scheme, composed of two cultivation systems (alone or intercropped) and three fertilizationtypes (organic, chemical and no fertilization), totaling 24 treatments with four replications in an area of 25 m² each. The results showed an influence effect of the source of fertilization and the intercroppingon the initial development of the crop, and the best results obtained were with the organic fertilization and the intercropping with common bean.

The simultaneous evaluation of qualitative and quantitative traits is an excellent tool to estimate the genetic divergence among accessionsof germplasm banks. The present study aimedto characterize and estimatethe genetic divergence among soybean food type accessionsbased on Gower algorithm and identifies promising combination among accessionsevaluated. A total of 64 soybean genotypes were studied, which 60arefood type soybean accessions, twoarecommercial cultivars also for human consumption,and two are grain type commercial cultivars. Three qualitative and seven quantitativetraits were used to estimate the genetic divergence among genotypes. The experiment was carried out in the experimental areaof the Universidade Estadual de Londrina during 2015/2016season, using a randomized complete block design with four repetitions. It was observed the presence of genetic variability to all traits evaluated. Thegrainyield trait was the mostefficientin discriminating theevaluated accessions,while plant height showed lower contribution. The UPGMA method showed the highestcoefficient of cophenetic correlation allowing the formation of six different groups. The crossings AL06 × AL22 and AL07 × AL22 are promising for obtaining superior genotypes destined to the in naturaconsumption and production of soy milk and tofu. The combination AL13 × AL60 is considered favorable for obtaining genotypes destined to natto production. The use of the AL12 and AL13 accessions as parents is advantageous for obtaining genotypes for the production of kuroname.

Increasing the nitrogen use efficiencyofcrop plants is a result of the improvement in the mechanisms involved in nitrogen uptake, translocation, assimilation and remobilization. In this study, tobacco plants with high accumulation of proline caused by the insertion of the VaP5CSF129Amutant gene under control of the constitutive promoter CaMV35S was used as a model to investigate the effect of overexpression of the transgene in the uptake and utilization of N. For this, an experiment was carried out in a completely randomized design, in a 2x5 factorial arrangement, with two genotypes (transgenic eventand untransformed control) and five levels of nitrogen fertilization (25, 50, 100, 200 and 400 kg N ha-¹), cultivated under greenhouse conditions. Plants were evaluated for height, number of leaves, dry mass, free proline content, nitrogencontent, total protein content and use of the applied N (efficiency of absorption -EAbs, efficiency of leaf utilization –EUtiland efficiency of plant use -EUN). The transgenic plantswith high proline accumulation were less efficient than the control plants in terms of nitrogen absorption (with lowerN levelsin root, leaves and wholeplant), which resulted in lower EAbs. There was no difference between the transgenic and control genotypesfor EUtil. However, the transgenic plants presented lower EUN in comparison tothe control plants. Our data showed thattransgenictobacco plants withhigh proline accumulation do not have potential for direct use in agricultural systems, since the alteration of the biochemical balance between the metabolisms of nitrogen and carbon did not result in plants with higher EUN.

The objective was to evaluate diluents and transport systems on semen quality frozen by CASA in Nellore bulls. Five semen collections of six bulls, diluted with the TRISand BotuBOV®, were transported out on two types of BotuBOX® and BotuFLEX® systems; frozen and analyzed by CASA. TM was higher (p <0.05) in the association of BotuBOV® + BotuFLEX® (47.3%) when compared to TRIS + BotuBOX® (9%). The PM was higher (p <0.05) BotuBOV® + BotuFLEX® (37%) when compared to TRIS + BotuBOX® (5.9%). The same for VSL, BCF and RAP, which were higher (p <0.05) in BotuBOV® + BotuFLEX® (65.1μm/s, 30Hz, 44.5%, respectively) when compared to semen in the TRIS + BotuBOX® (47.6μm/s, 21.5Hz, 6.9%, respectively). It is concluded that BotuBOV® in association with the refrigerated system of semen BotuFLEX® was considered by CASA to be the best association when referring to sperm kinetics for cryopreservation of bovine semen.
How (ir)rational is it to believe in contradictory conspiracy theories?
Authors: Lukić Petar , Žeželj Iris , Stanković Biljana
Published: February 2019

There is evidence that not only believing in one conspiracy theory (CT) makes a person more probable to believe in others, however unrelated their content is, but that people can even believe in contradictory CTs about a single event. After piloting locally relevant conspiracy theories on a convenient Serbian speaking sample (N = 152), we sought to replicate this finding on a larger sample (N = 252), but introduced several changes. We differentiated necessarily and probably mutually exclusive CTs, and interviewed the participants who answered contradictory to understand the reasoning behind it. The participants were more prone to endorse probably than necessarily exclusive items (we registered positive correlations in former and no correlation or negative correlation in later). Two strategies enabled them to overcome the contradiction: (a) distilling the crucial content and downplaying other information and (b) treating the contradictory scenarios as possible versions of events. Taken together, these results indicate that participants are not as irrational as sometimes portrayed.
Refinement of outcome bias measurement in the parental decision-making context
Authors: Damnjanović Kaja , Ilić Sandra , Pavlović Irena , Novković Vera
Published: February 2019

The aim of this study was twofold: one was to test the impact of the involvement on the parental outcome bias, and the second was to refine the measurement of outcome bias, normally reported as the difference between evaluations of a single decision, with different outcomes assigned to it. We introduced the evaluation of a decision without an outcome, to induce theoretically normative evaluation, unbiased by outcome, from which the evaluation shift could be calculated in either direction. To test this refinement in the parental decision-making context, we produced childcare dilemmas with varying levels of complexity, since the rise of complexity induces stronger bias. Complexity was determined by the particular combination of two factors: parental involvement in a decision - the amount of motivation, interest and drive evoked by it – and whether the decision was health-related or not. We presented parents with the decisions for evaluation, followed by a positive and a negative outcome, and without an outcome. The results confirm the interaction between involvement and domain on decision evaluation. Highly involving decisions yielded weaker outcome bias than low-involvement decisions in both health and non-health domain. Results also confirm the validity of the proposed way of measuring OB, revealing that in some situations positive outcomes skew evaluations more than negative outcomes. Also, a highly-involving dilemma followed by negative outcome did not produce significantly different evaluation compared to evaluation of a decision without outcome. Thus, adding a neutral position rendered OB measurement more precise and our involvement-related insights more nuanced.

Method to collect ground truth data for walking speed in real-world environments: description and validation
Authors: Aigner Gerhard , Grimm Bernd , Lederer Christian , Daumer Martin
Published: February 2019

Background. Physical activity (PA) is increasingly being recognized as a major factor related to the development or prevention of many diseases, as an intervention to cure or delay disease and for patient assessment in diagnostics, as a clinical outcome measure or clinical trial endpoint. Thus, wearable sensors and signal algorithms to monitor PA in the free-living environment (real-world) are becoming popular in medicine and clinical research. This is especially true for walking speed, a parameter of PA behaviour with increasing evidence to serve as a patient outcome and clinical trial endpoint in many diseases. The development and validation of sensor signal algorithms for PA classification, in particular walking, and deriving specific PA parameters, such as real world walking speed depends on the availability of large reference data sets with ground truth values. In this study a novel, reliable, scalable (high throughput), user-friendly device and method to generate such ground truth data for real world walking speed, other physical activity types and further gait-related parameters in a real-world environment is described and validated.

Methods. A surveyor’s wheel was instrumented with a rotating 3D accelerometer (actibelt). A signal processing algorithm is described to derive distance and speed values. In addition, a high-resolution camera was attached via an active gimbal to video record context and detail. Validation was performed in the following main parts: 1) walking distance measurement is compared to the wheel’s built-in mechanical counter, 2) walking speed measurement is analysed on a treadmill at various speed settings, 3) speed measurement accuracy is analysed by an independent certified calibration laboratory - accreditation by DAkkS applying standardised test procedures.

Results: The mean relative error for distance measurements between our method and the built-in counter was 0.12%. Comparison of the speed values algorithmically extracted from accelerometry data and true treadmill speed revealed a mean adjusted absolute error of 0.01 m/s (relative error: 0.71 %). The calibration laboratory found a mean relative error between values algorithmically extracted from accelerometry data and laboratory gold standard of 0.36% (0.17-0.64 min/max), which is below the resolution of the laboratory. An official certificate was issued.

Discussion. Error values were a magnitude smaller than the any clinically important difference for walking speed.

Conclusion. Besides the high accuracy, the presented method can be deployed in a real world setting and allows to be integrated into the digital data flow.
260 Voyages Beneath the Sea: A global assessment of biodiversity and research effort at deep-sea hydrothermal vents
Authors: Thaler Andrew D , Amon Diva
Published: February 2019

For over forty years, hydrothermal vents and the communities that thrive on them have been a source of profound discovery for deep-sea ecologists. These ecosystems are found throughout the world on active plate margins as well as other geologically active features. In addition to their ecologic interest, hydrothermal vent fields are comprised of metallic ores, sparking a nascent industry that aims to mine these metal-rich deposits for their mineral wealth. Here we provide the first systematic assessment of biodiversity at hydrothermal vents normalized against research effort. Cruise reports from scientific expeditions as well as other primary literature were used to characterize the extent of exploration, determine the relative biodiversity of different biogeographic provinces, identify knowledge gaps related to the distribution of research effort, and prioritize targets for additional sampling to establish biodiversity baselines ahead of potential commercial exploitation. The Northwest Pacific, Southwest Pacific, and Southern Ocean biogeographic provinces were identified as high biodiversity using rarefaction of incidence data, whereas the North East Pacific Rise, Northern East Pacific, Mid-Atlantic Ridge, and Indian Ocean provinces had medium biodiversity, and the Mid-Cayman Spreading Center was identified as a province of relatively low biodiversity. A North/South divide in the extent of biological research and the targets of hydrothermal vent mining prospects was also identified. Finally, we provide an estimate of sampling completeness for each province to inform scientific and stewardship priorities.
Coding of whisker motion across the mouse face
Authors: Severson Kyle S , Xu Duo , Yang Hongdian , O'Connor Daniel H
Published: February 2019

Haptic perception synthesizes touch with proprioception, the sense of body position. Humans and mice alike experience rich active touch of the face. Because most facial muscles lack proprioceptor endings, the sensory basis of facial proprioception remains unsolved. Facial proprioception may instead rely on mechanoreceptors that encode both touch and self-motion. In rodents, whisker mechanoreceptors provide a signal that informs the brain about whisker position. Whisking involves coordinated orofacial movements, so mechanoreceptors innervating facial regions other than whiskers could also provide information about whisking. To define all sources of sensory information about whisking available to the brain, we recorded spikes from mechanoreceptors innervating diverse parts of the face. Whisker motion was encoded best by whisker mechanoreceptors, but also by those innervating whisker pad hairy skin and supraorbital vibrissae. Redundant self-motion responses may provide the brain with a stable proprioceptive signal despite mechanical perturbations during active touch.

Effects of root phenotypic changes on the deep rooting of Populus euphratica seedlings under drought stresses
Authors: Ye Zi-qi , Wang Jian-ming , Wang Wen-juan , Zhang Tian-han , Li Jing-wen
Published: February 2019

Background

Deep roots are critical for the survival of Populus euphratica seedlings on the floodplains of arid regions where they easily suffer drought stress. Drought typically suppresses root growth, but P. euphratica seedlings can adjust phenotypically in terms of root-shoot allocation and root architecture and morphology, thus promoting deep rooting. However, the root phenotypic changes undertaken by P. euphratica seedlings as a deep rooting strategy under drought conditions remain unknown.

Methods

We quantified deep rooting capacity by the relative root depth (RRD), which represents the ratio of taproot length to plant biomass and is controlled by root mass fraction (RMF), taproot mass fraction (TRMF), and specific taproot length (STRL). We recorded phenotypic changes in one-year-old P. euphratica seedlings under control, moderate and severe drought stress treatments and assessed the effects of RMF, TRMF, and STRL on RRD.

Results

Drought significantly decreased absolute root depth but substantially increased RRD via exerting positive effects on TRMF, RMF, and STRL. Under moderate drought, TRMF contributed 55%, RMF 27%, and STRL 18% to RRD variation. Under severe drought, the contribution of RMF to RRD variation increased to 37%, which was similar to the 41% for TRMF. The contribution of STRL slightly increased to 22%.

Conclusion

These results suggest that the adjustments in root architecture and root-shoot allocation were predominantly responsible for deep rooting in P. euphratica seedlings under drought conditions, while morphological changes played a minor role. Moreover, P. euphratica seedlings rely mostly on adjusting their root architecture to maintain root depth under moderate drought conditions, whereas root-shoot allocation responds more strongly under severe drought conditions, to the point where it plays a role as important as root architecture does on deep rooting.

This phenomenological study ascertained the plight and aspirations of young criminologists who were engaged in teaching practice. Two research questions were answered: (1) What is the plight of young criminologists in the teaching practice; and (2) What are the aspirations of young criminologists in the teaching practice? It involved ten research informants presently employed with higher education institutions (HEIs) within Central Visayas, Philippines. The collection of information techniques used were in-depth interviews and focus group discussion. The research participants shared their plight in the teaching practice and their aspirations in their career. Nine themes surfaced in this study: low confidence, difficulties in oral and written communication, a teacher by accident, lack of preparation for teaching practice, job satisfaction, professional status, technical skills, professional & personal growth, and support to enhance teaching competence.

Published: February 2019

Conflict is inevitable in life and the challenge is how leaders can precisely manage it. In this respect, for pragmatic and academic purposes and to provide useful information on conflict management styles for the harmonious and globalized working environment this study determined the appropriate conflict management styles to address specific organizational related conflicts in HEIs of Sulu. To obtain the needed data, the researcher employed the purposive random sampling method, using twenty-five (25) educational managers in Higher Educational Institutions (HEIs) of Sulu includes 230 faculty members to determine the most common organizational-related conflict and the most effective management styles. Employed descriptive- survey method 0.192 is greater than 0.05 confidence levels that provide evidence to say conflict management styles of educational managers are not significant predictor to the teaching performance of the faculty in HEIs. Educational managers in HEIs should initiate an action plan to improve the programs of managing conflict to approximately make these styles uniform in HEIs being the people belong to common tribe and lifestyles. Moreover, mentoring the workers through the experience managers should be encouraged at the workplace. Finally, the study on conflict is highly recommended to scrutinize the effect on the faculty.

Authors: Dos Reis Dayane Letícia Rodrigues
Published: February 2019

A geodiversidade é bastante visada pelo turismo e, neste sentido, o geoturismo evidencia os aspectos e promove a divulgação do meio abiótico em uma linguagem acessível ao publico leigo. Diante do potencial de uso da geodiversidade, é necessário que se estabeleçam medidas de planejamento para sua utilização sustentável. Sendo assim, o presente artigo tem como objetivo geral identificar geossítios localizados no Parque Estadual Serra do Rola Moça (PESRM), Minas Gerais, realizando avaliação quantitativa e do risco de degradação com ênfase no uso turístico. Os procedimentos metodológicos utilizados foram pesquisa bibliográfica e levantamento de dados em campo. Para a quantificação dos geossítios foi adaptada à metodologia proposta por Brilha (2015), ou seja, foram realizadas mudanças em alguns dos critérios sugeridos pelo autor, levando em consideração a realidade da área de estudo. A partir da identificação e quantificação dos geossítios foi evidenciado que o geoturismo pode ser desenvolvido no PESRM, embora se tenha identificado algumas deficiências na infraestrutura dos geossítios. Dessa forma, acredita-se que o desenvolvimento de atividades geoturísticas irá contribuir para o conhecimento e conservação da geodiversidade local, mas para isso é necessário à elaboração de estratégias que envolvam os gestores do PESRM, a comunidade local e acadêmica.

Authors: Eke M. O. , Ahure D. , Donaldben N. S.
Published: February 2019

Cookies was produced from wheat (Triticum, spp), acha (Digitaria exilis), and sprouted soybeans (Glycine max) flour blends. The acha and soybeans were processed into flour and used to substitute wheat flour at different proportions with 100:0:0 wheat, acha and sprouted soybeans flour (WAS) as the control, 60:30:10, 50:40:10, 45:45:10, 40:50:10 and 35:55:10 (WAS). The functional properties of the wheat, acha and sprouted soybeans flour blends, physical properties and proximate compositions of the cookies were determined. The functional properties of the flour samples shows that the bulk density, wettability, water absorption capacity, oil absorption capacity and gelatinization temperature ranged from 0.63 g/ml-0.99 g/ml, 10.21-12.98 g/sec, 6.53-12.52 g/g, 0.52-0.66 g/g and 63.7-65.1ºC respectively. There were significant differences (p<0.05) in all the values. The proximate composition of cookies sample showed that crude protein, crude fat, crude fibre, ash, moisture and carbohydrate content ranged from 12.14-16.48 %, 2.10-3.74 %, 1.76-2.55 %, 2.75-8.55 %, 9.18-9.50 % and 59.37-72.06 % respectively. The physical properties of cookies showed that the weight, diameter, thickness and spread ratio ranged from 15.61-17.11g; 61.59-63.20mm; 9.88-11.99mm and 5.28-6.24 respectively. The control sample cookies from 100:0:0 (WAS), wheat, acha and sprouted soybeans flour blends sample had the highest sensory scores in terms of the taste, appearance, texture, aroma and overall acceptability. There was significant difference (p<0.05) in the colour, texture and aroma but there was no significant difference (p>0.05) in the taste and overall acceptability in 60:30:10, 50:40:10, 45:45:10, 40:50:10 and 35:55:10 (WAS) samples.
Papermaking Using Willow (Salix dasiclados) as a Hardwood Source – A Handsheet and Pilot Paper Machine Study
Authors: Dölle Klaus
Published: February 2019

This laboratory handsheet and Fourdrinier pilot paper machine study examine the suitability of willow as a commercial hardwood pulp replacement including utilizing recycled pulp for paper production. The hand sheet study contains 16 different and the pilot paper machine study eight different furnish mixtures. For both studies, the base sheet consists of a 40% softwood and 60% hardwood commercial pulp mixture, followed by replacing the hardwood with bleached willow Kraft pulp. Deinked pulp, as recycled fibres, at 5% increments up to 100% for the handsheet study and at 10%, 20%, 30%, 50%, 70% and 90% for the pilot paper machine study is added to the base pulp mixture. Both the handsheet and the FPPM study revealed that willow Kraft pulp can replace commercial hardwood pulp fibres.  Basis weight, calliper and stiffness as related properties showed comparable results for the handsheet study. Willow Kraft fibres tend to be bulkier and denser than the used hardwood fibres.

Tensile and tear index show comparable properties for the handsheet and pilot paper machine study, except for the 50%, 70% and 90% DIP containing paper sheets.

Porosity values for the hansheet study showed lower results than the base sheet, whereas the FPPM study showed higher results except for the 70% and 90% DIP containing handsheet. Comparable results are shown for opacity. Brightness levels were significantly lower due to the lower brightness of the manufactured willow Kraft and deinked pulp fibre furnish.

Despite the opportunity of replacing commercial hardwood with willow, more research needed to optimize willow into pulp fibres and preparation of the fibres for papermaking.
Anatomical Aspects of Mycobacterium tuberculosis-Associated Destructive Cranial Lesions
Authors: Wessels Quenton , Taylor Adam Michael , Correia Janine Carla
Published: February 2019

The authors report two cases of destructive cranial lesions associated with Mycobacterium tuberculosis–HIV coinfection in a male and female cadaver. Both cadavers were of African origin, from the Western Cape, South Africa. The authors present grossly abnormal tuberculosis–associated lesions of the anterior and middle cranial fossae, involving the ethmoid and sphenoid bones. Both individuals presented with tubercular intrasellar masses and obliteration of the paranasal sinuses. Current literature on cases such as these are extremely rare and others typically focus on lesions of the calvarium. Here we report on the gross anatomical findings as well as the relevant anatomical aspects of the probable aetiology. Both cases presented here hold interest for medical professionals in Africa and other geographic regions. It further illustrates the importance of understanding the venous drainage of the paranasal sinuses when considering the manifestation and treatment of extrapulmonary TB.

The common bean (Phaseolus vulgaris L) can be cultivated practically throughout the year in different regions of Brazil, provided there are no water and temperature limitations. This study was carried out in a Quartzarenic Neosol, in the municipality of Cassilândia, state of Mato Grosso do Sul (MS), Brazil, in the 2016/2017 agricultural year. This study aimed to establish the linear and spatial interrelations of the penetration resistance (PR), gravimetric moisture (GM), and organic matter content (OM) with bean grain yield (GY) in the 0.00-0.10 and 0.10-0.20 m soil layers, collected in a mesh of 117 georeferenced points [81 points of the base mesh (6 m spacing among points)] and 36 mesh points with higher density (2 m spacing among points). Data analysis was carried out by statistical and geostatistical techniques that enabled to note that the organic matter content correlates linearly and negatively with penetration resistance, indicating that soil management practices aiming to increase its profile improve its physical conditions and therefore the bean grain development and yield. The gravimetric moisture and soil organic matter content correlate spatially, directly, and linearly with bean grain yield, proving to be the best properties among those surveyed to estimate and increase its agricultural productivity.
