Risk of asphyxiation from Vernagel ingestion
Authors: Wickstone L , Shayah A , Agada F
Published: June 2018

Vernagel (sodium polyacrylate) is a powder commonly used in hospitals worldwide for the management and disposal of body fluids. It reacts with fluids to form a semisolid gel. Its main use is to reduce spillages. If ingested, this substance presents significant risk of asphyxiation. There have been 15 reported cases of Vernagel ingestion in 6 years and 1 death from asphyxiation. We present the case of an elderly patient who was admitted following a fall. He accidentally ingested a sachet of Vernagel during the early hours of the morning. An urgent rigid panendoscopy was performed and the material was evacuated using suction aspiration. Patients should be supervised when using Vernagel on the ward, to avoid ingestion. Ear, nose and throat doctors should be aware of Vernagel and its properties. Owing to the risk of airway obstruction, excellent coordination between the anaesthetist and surgeon is crucial, and prompt management is required.
Haematomas after carotid endarterectomy can be reduced by direct pressure to the neck postoperatively
Authors: Saghir R , Humm G , Rix T
Published: June 2018

Introduction

A recognised complication of carotid endarterectomy (CEA) is postoperative haematoma, which can threaten the airway. Previous studies have looked at medical methods of preventing this complication. This study aims to evaluate the impact of simple direct pressure postoperatively on the development of haematoma.

Materials and methods

From 2011 to 2016, 161 consecutive CEA were performed by a single surgeon or trainee under supervision. After 80 operations, the postoperative technique was altered, with additional pressure being applied by the surgeon to the skin incision from completion of suturing until each patient was awake in the recovery room. The rates of postoperative haematoma and other complications were compared between the pre- and post-intervention groups, as well as grade of surgeon, urgency of operation and antiplatelet/anticoagulant use.

Results

Post-carotid haematomas were eliminated in the post-intervention group (0/81); in the pre-intervention group 7/80 patients developed haematoma (P < 0.05). There were no significant differences in urgency of surgery, antiplatelet/anticoagulant use, grade of surgeon or other complications (stroke: 2/80 vs 0/81 P < 0.05), suggesting that this was not a learning curve effect.

Discussion

The results suggest that applying direct pressure helps to reduce oozing, provides time to monitor and identify additional bleeding and protects the wound from excessive strain that may be caused by coughing while the patient wakes up. We advise that the lead surgeon should apply such pressure to ensure precise and focal targeting, for maximum effect.

Conclusion

During recovery from CEA, focused and prolonged pressure by the operating surgeon is a highly effective method of reducing haematoma.
Temores del Imperio: la Amazonia brasileña en el siglo XIX
Authors: Ruiz-peinado Alonso José Luis
Published: June 2018

La Amazonia brasileña durante la primera mitad del siglo XIX estuvo marcada por una extraordinaria inestabilidad político-militar. Su adhesión tardía a la independencia de Brasil (1823) y las diversas revueltas que se produjeron, fueron procesos que tuvieron como protagonistas no sólo a las elites políticas lusobrasileñas, sino también a diferentes grupos cimarrones e indígenas que actuaban desde amplios e intrincados espacios de frontera, atentos a las ideas revolucionarias que provenían del exterior y que jugaron un papel fundamental en la construcción de la especificidad del norte de Brasil.

Authors: Park Sanghoon , Kaplan Howard , Schlaf Rudy , Tridas Eric
Published: June 2018

The Makecourse-Art is a makerspace designed to promote undergraduate students’ aesthetic design skills as well as functional design skills using an interdisciplinary team approach at the University of South Florida. To overcome the unique challenges of the Makecourse (earlier version) and to maximize students’ design efforts working on an engineering project in the classroom, the Makecourse-Art incorporated a flipped classroom model utilizing two instructional methods with corresponding activities. First, the explicit form of instruction is delivered through asynchronous video lectures/tutorials, including topics such as Arduino programming, CAD modeling with the Autodesk Maya, Mudbox, and coding skills. Second, interactive team-based classroom activities are offered to students based on student-centered learning theories such as peer-assisted collaborative learning and problem-based learning. In this paper, we present the design case of the Makecourse-Art with detailed descriptions of the components, and explain the key design decisions, obstacles during the design process, and how the challenges were resolved. In addition, we provide step-by-step examples of students’ engineering design experiences with visual images.

Published: June 2018

Culturally responsive science teaching has been associated with several positive academic outcomes for students of color, including improved science achievement, attitudes, and identities. Given the chronic science performance gap between students of color and white peers, culturally responsive teaching seems ideal for mitigating this disparity. Traditional teacher preparation programs, however, neither emphasize nor require multicultural science education coursework. Unfortunately, many science teachers exit preparation programs without critically examining their beliefs about culturally diverse students or increasing their confidence in working with them. In response to this concern, we designed a theoretically- and contextually-grounded induction course to support culturally responsive secondary science teacher development. The purpose of this four-week course was to engage beginning secondary science teachers (1-5 years of teaching experience) in activities, discussions, and reflections raising awareness of the importance of attending to attitudes about culturally diverse students, as well as abilities to incorporate students’ backgrounds into science instruction.
Course goals included improving teachers’: understanding of culturally responsive pedagogy (CRP); sociopolitical awareness and knowledge of their cultural identities; knowledge of and attitudes toward culturally diverse students, their families, and communities; critical reflection on classroom practices; and abilities to design culturally responsive science curriculum units integrating families’ funds of knowledge and/or sociopolitical ties. In this paper, we share our design and implementation experiences, as well as teacher outcomes. Continued conversations between researchers, teacher educators, and others involved in advancing culturally responsive science teaching are crucial to the academic success of culturally diverse student populations.
Opportunities and Challenges of Retrieval Analysis: The Role of Standardized Periprosthetic Tissue and Fluid Analysis for Assessing an Aggravated Host Response
Authors: Torosyan Yelizaveta , Bowsher John G. , Kurtz Steven M. , Mihalko William M. , Marinac-Dabic Danica
Published: June 2018

Despite the recent advances with implantable devices, implant longevity and functionality may be compromised by degradative processes such as wear and corrosion, and the implant performance may be further complicated by the resultant host responses. As a window into in vivo implant performance, retrieval analysis is paramount for providing an essential feedback for improving new biomaterial choices and device designs and for securing a decision-making accounting for interindividual variability of real-world performance. Acknowledging the need for leaving the device-tissue interface intact, the current retrieval recommendations (e.g., ASTM F561-13) refer to the importance of proper collecting and handling of the adjacent tissues and fluids so as not to interfere with device/tissue-related analyses or jeopardize patient safety. However, without further stipulation of the utmost importance of comprehensive histopathological assessment, the current retrieval practices remain mostly focused on the mechanical analyses of explanted devices, without sufficiently addressing the corresponding tissue/biofluid changes at microscopic and molecular levels. The recently accumulated evidence on biological responses that comprise implant reactivity provides an impetus for rethinking the retrieval-related potential to enhance our understanding of the implant-elicited host responses and thereby improve preclinical biocompatibility testing and enable more predictive evaluation of in vivo implant performance. The retrieval assessment may be improved by a more detailed characterization of the implant debris in terms of its cellular uptake (e.g., phagocytosability), immune and tissue-destructive responses (e.g., not limited to lymphocyte-mediated alterations), as well as other parameters the implant was exposed to that might affect implant longevity (e.g., mechanical alignment, cement technique, soft tissue support). The revised retrieval practices may help facilitate the Center for Devices and Radiological Health's mission and priorities for building the infrastructure and assessment tools for the National Evaluation System for Health Technology.
Characterization of Material Loss from Femoral Stem Taper Surfaces through Development of a Responsive Morphological Filtering Technique
Authors: Dransfield Karl , Racasan Radu , Blunt Liam , Bills Paul
Published: June 2018

The presence of taper junctions in hip arthroplasty designs has been suggested to contribute to premature clinical failure, in part due to corrosion-assisted material loss. Characterization of the material loss at the taper junction is an important factor in determining not only taper performance but also the requirement for revision of primary stems. It is therefore clear that a robust metrological solution to this issue is required to understand the connection between damage to the stem surface and explicit criteria to initiate retrieval. Previously detailed studies have focused on the characterization of tapers with plain-machined surfaces, with most research concentrated on femoral head tapers. This study details a measurement and analysis method to characterize threaded-type microgroove trunnion surfaces that make up a large proportion of current implanted stem taper designs. Femoral stem designs from two manufacturers were measured using a Talyrond 365 (Ametek, Inc., Berwyn, PA) out-of-roundness measurement machine. Submicron measurement resolution was achieved, and the use of a 5-µm radius diamond stylus meant that any mechanical filtering effect was insignificant compared to conventional contact measurement techniques. The grooved topography of the trunnion surface presents challenges in ascertaining an “unworn” surface from which surface damage data are then separated. A novel filter was developed to delineate form and material loss. The filter is responsive such that the wavelength and amplitude of an individual component’s microgrooves can be removed from the analysis. Application of the filter to leveled data allowed bearing area analysis to be utilized to determine an accurate volume of material loss based on the residual form-removed data. A cohort of as-manufactured samples (n = 21) were measured and used to validate the filtering methodology. A component exhibiting induced surface wear (n = 1) was measured using the same instrumentation and processed using the filtering technique.

Authors: Perkins Meredith , Lowell Julie , Kerkhof Anita , Mihalko William M.
Published: June 2018

Inflammatory cytokines have been proposed as potential biomarkers for damage in total knee arthroplasty (TKA). This study sought to compare the levels of inflammatory cytokines (TNF-α, IL-1β, IL-6, IL-8, MCP-1, MIP-1α, MIP-3α, GM-CSF, and M-CSF) in synovial fluid of retrieved cadaveric primary TKAs, painful TKAs, and failed TKAs obtained at the time of revision. Twenty-five cadaveric specimens with primary TKAs were procured, and synovial fluid was collected. Seven synovial aspirates were collected during revision surgery from patients with failed primary TKAs, and twelve synovial aspirates were collected during clinic visits from patients with painful primary TKAs. Synovial samples were analyzed using a premixed Luminex Multiplex Screening Assay kit for detection of human inflammatory cytokines. A Kruskal-Wallis statistical test with Dunn's multiple comparison post hoc test and an assumed significance (p < 0.05) was used. Statistical analysis revealed a significant difference (p = 0.028) between IL-6 concentrations present in painful and cadaveric samples. No significant difference (p = 0.343) was found among the mean MCP-1 concentrations across the three sample groups. The cadaveric and painful samples had elevated MIP-3α compared to the revision samples upon initial inspection. Statistical analysis revealed a significant difference between cadaveric and revision sample groups. The cadaveric specimens had concentrations that were significantly elevated in comparison to the painful (p < 0.0001) and revision samples (p = 0.0015). IL-6 may be a potential biomarker for damage in a TKA. To better understand the role of MIP-3α, a future study should increase the sample size of the painful and revision groups. Future research will investigate the role of M-CSF concentrations as indicators in progression of TKA failure. Understanding the roles of these inflammatory cytokines throughout the progression of primary TKA complications may improve the diagnosis and treatment of painful TKAs.

Published: June 2018

Analysis of retrieved implants is a multistep process that can be approached in a variety of ways. To researchers, this analysis is vital to assessing how the implant functioned after surgery. Traditionally, this involves examination of components by one or several experts who then give feedback on the severity of observable damage. Engineering approaches attempt to minimize subjectivity by introducing standardized techniques that can quantify damage, such as microcomputed tomography analysis of retrieved polyethylene components. Methods such as these provide an objective way to measure damage and can be used in addition to subjective techniques such as visual inspection. This chapter will entail a review of the available processes that can be utilized to properly analyze how and why a polymer insert in a total knee arthroplasty implant failed.
Climate change, community capitals, and food security: Building a more sustainable food system in a northern Canadian boreal community
Authors: Spring Andrew , Carter Blair , Blay-Palmer Alison
Published: June 2018

Canada’s North offers unique food systems perspectives. Built on close cultural and spiritual ties to the land, the food systems within many northern communities still rely on the harvesting and gathering of traditional food and function through the sharing of food throughout the community. However, social, economic and environmental pressures have meant that some communities rely more on food purchased from the stores, which can be unhealthy and expensive, leading to high rates of food insecurity and chronic health problems in many communities in the North. Northern communities are now dealing with the impacts of climate change that are increasing pressure on the food system by limiting both access to the land and the availability of traditional food sources. This research presents a case study from the Northern Canadian boreal community of Kakisa, Northwest Territories. Using a Participatory Action Research (PAR) methodology, community members play an active role in identifying threats to the community food system, as well as developing community-based solutions to foster adaptation and transformation of their food systems to become more resilient to the impacts of climate change. By using the Community Capitals Framework to identify multiple stressors on the food system this research illustrates how a community can allocate available capitals to adapt to the impacts of climate change as well as identify which capitals are required to build a more sustainable food system.

Published: June 2018

Abstract X-ray microtomography (microCT) is a nondestructive technique used to assess bone morphometry. For an accurate analysis, it is necessary to segment the bone tissue from the background images, avoiding under- or overestimation of the real bone volume. Thus, segmentation methods for microCT can influence the accuracy of bone morphometry analysis. The purpose of this study was to compare two different image segmentation methods available on microCT software (subjective and objective) regarding to the human bone morphometric analysis. Sixteen samples containing a fixation screws covered by 0.5-1mm of bone were scanned using the SkyScan 1173 scanner. Three examiners segmented the microCT images subjectively and recorded the threshold values. Subsequently, an objective segmentation was also done. The 3D analysis was performed for both images using the values previously determined in CTAn software. Five bone morphometric parameters were calculated (BV/TV, Tb.Th, Tb.N, Tb.Sp, Conn.Den) and used as dependent variables. ANOVA showed no significant differences between the methods concerning BV/TV (p=0.424), Tb.N (p=0.672), Tb.Th (p=0.183), Tb.Sp (p=0.973) and Conn.Den (p=0.204). Intra- and interobserver agreement ranged from satisfactory to excellent (0.55-1 and 0.546-0.991, respectively). Therefore, results obtained with subjective threshorlding were similar to those obtained with objective segmentation. Since objective segmentation does not have human input and it is a truly objective method, it should be the first choice in microCT studies that concern homogeneity and high resolution human bone sample.

Published: June 2018

Abstract Patients undergoing radiotherapy treatment present more susceptibility to dental caries and the use of an orthodontic device increases this risk factor due to biofilm accumulation around the brackets. The objective of this study was to evaluate the shear bond strength to irradiated permanent teeth of orthodontic brackets bonded with conventional glass ionomer cement and resin-modified glass ionomer cement due to the fluoride release capacity of these materials. Ninety prepared human premolars were divided into 6 groups (n=15), according to the bonding material and use or not of radiation: CR: Transbond XT composite resin; RMGIC: Fuji Ortho LC conventional glass ionomer cement; GIC: Ketac Cem Easymix resin-modified glass ionomer cement. The groups were irradiated (I) or non-irradiated (NI) prior to bracket bonding. The specimens were subjected to a fractioned radiation dose of 2 Gy over 5 consecutive days for 6 weeks. After the radiotherapy, the brackets were bonded on the specimens with Transbond XT, Fuji Ortho LC and Ketac Cem Easymix. After 24 h, the specimens were subjected to shear bond strength test. The image of enamel surface (classified by Adhesive Remnant Index - ARI) was also evaluated and its frequency was checked among groups/subgroups. The shear bond strength variable was evaluated with ANOVA and Tukey’s post-hoc test. GIC group showed the lowest adhesion values among the groups (p<0.05). There was no statistically significant difference among non-irradiated and irradiated groups (p>0.05). As for the ARI, the CR-I group showed the highest material retention on enamel surface among the irradiated groups. RMGIC group showed the highest values for shear bond strength and presented ARI acceptable for clinical practices.

Abstract The aim of this study was to evaluate the influence of the prophylactic and therapeutic supplementation with omega 3 polyunsaturated fatty acids (w-3 PUFAs) on the lipid profile and periapical bone resorption in rats with apical periodontitis. Forty male rats were divided into groups: control rats (C), rats treated with w-3 PUFAs (C+O), rats with pulp exposure-induced apical periodontitis (AP), and rats with AP treated with w-3 PUFAs (AP+O). The administration of w-3 PUFAs was carried out orally once a day for 15 days before pulp exposure and, subsequently, for an additional 30 days after pulp exposure. AP was induced by exposing pulpal tissues to the oral environment. The samples were collected after 30 days. Triglycerides and cholesterol levels were enzymatically measured using the Trinder method. The jaws were collected and submitted for histological analysis. Two-way analysis of variance and Kruskal-Wallis tests were used for statistical analysis, and the significance was set at p<0.05. The triglyceride levels of the AP group were significantly higher than those of the C, C+O and AP+O groups (p<0.05). However, the difference in the cholesterol levels among the groups was not significant (p>0.05). Rats with AP showed larger areas of bone resorption as well as higher inflammatory intensity compared with rats with AP supplemented with w-3 PUFAs. It may be concluded that the presence of multiple AP foci increased the triglyceride levels. In addition, omega 3 supplementation might reduce these levels in rats with AP, as well as the bone resorption areas of periapical tissues.

Published: June 2018

Abstract This study investigated the effect of blood-contamination on the push-out bond strength of BiodentineTM (BD) and MTA Angelus® (MTA-A) to root dentin over time. Twenty-five teeth were sectioned horizontally to obtain 120 root slices. The lumens were filled with MTA-A or BD: 60 for each cement (30 uncontaminated and 30 blood contaminated). Push out bond strength to dentin was assessed at 24 h (n=10), 7 days (n=10) and 28 days (n=10). Failure modes were classified as: cohesive, adhesive or mixed failure. Two-way ANOVA was used to investigate the interaction between blood contamination vs. hydration period. Mann Whitney test compared different materials in each period, and it also compared the contaminated versus uncontaminated material for each period. Friedman, followed by Dunn`s test, compared periods of hydration for each material, regardless of blood contamination. Failure modes were reported descriptively. The interaction hydration period vs. blood contamination was highly significant for MTA-A (P=0.001) and it was not significant for BD (P=0.474). There were no differences between bond strength of uncontaminated and contaminated BD in any of the periods. Bond strength of uncontaminated MTA-A increased at each time of hydration; but it remained stable over time for blood-contaminated samples. BD had higher bond strength than MTA-A in all periods of hydration. Cohesive failure predominated. Only for MTA-A, the over time bond strength to dentin was affected by blood contamination.

Abstract The aim of the present study was to evaluate the cyclic fatigue of two anatomic finishing files: XP-Endo Finisher and XP-Clean. Roughness pattern and the micro-hardness of the files were also assessed. Instruments were subjected to cyclic fatigue resistance measuring the time to fracture in an artificial stainless-steel canal with a 60° angle and a 5-mm radius of curvature. The fracture surface of all fragments was examined with a scanning electron microscope. The roughness of the working parts was quantified by using a profilometer and the micro-hardness test was carried out using a Vickers hardness tester. Results were statistically analyzed using a student´s t-test at a significance level of P < 0.05. Weibull analysis was also performed. XP-Endo Finisher presented significantly longer cyclic fatigue life than XP-Clean instruments (P<0.05). XP-Endo Finisher was able to withstand 1000% more cycles to fracture when compared to XP-Clean instruments. SEM visual inspection of the fracture surfaces revealed fractographic characteristics of ductile fracture in all tested instruments; wide-ranging forms of dimples were identified and no plastic deformation in the helical shaft of the fractured instruments was observed. When mean life was compared XP-Endo Finisher lasted longer than XP-Clean with a probability of 99.9%. XP-Endo Finisher instruments also exhibited significantly lower roughness than XP-Clean instruments (P<0.05). No differences in the micro-hardness was observed between the files (P>0.05). It can be concluded that XP-Endo Finisher instruments showed improved performance when compared with XP-Clean instruments, demonstrating higher cyclic fatigue resistance and lower roughness.

Abstract In view of the gastrointestinal problems generated by the ketoprofen use, the ketoprofen association with omeprazole is available on the market. However, this association efficacy in acute pain control has not been established. Bilateral extraction of lower third molars in similar positions is currently the most used model for the evaluation and investigation of the efficacy and pharmacological effects of new compounds for the treatment of acute postoperative pain. The randomized and crossover study consisted in evaluating the clinical efficacy of therapy performed by ketoprofen 100 mg (twice daily-b.i.d.) versus ketoprofen 200 mg + omeprazole 20 mg (once daily-q.d.) to pain, swelling and trismus control in the bilateral extraction model of lower third molars in similar positions in two different appointments, in 50 volunteers. Volunteers reported significantly less postoperative pain at various post-operative periods and consumed less rescue analgesic medication (acetaminophen 750 mg) throughout the study when they took the combination of ketoprofen 200 mg + omeprazole 20 mg (q.d.). Following administration of both study drugs, no gastrointestinal adverse reactions were reported by volunteers. Furthermore, the evaluations of the drugs in pain control by the volunteers were significantly favorable to ketoprofen 200 mg + omeprazole 20 mg (q.d.). For swelling and trismus control, the treatments presented similar results. In conclusion, when volunteers took ketoprofen 200 mg + omeprazole 20 mg (q.d.), they reported significantly less postoperative pain at various post-surgical periods and consumed less rescue analgesic medication throughout the study compared with ketoprofen 100 mg (b.i.d).

Authors: Sanjay Mattam , Bommireddy Babulreddy , Umamahesh Matapathi
Published: June 2018

Background: Ankle sprain accounts for 15-20% of sports injuries. They are complex injuries and studies that better delineate the etiology are needed. The accuracy of ultrasound as a diagnostic modality of ankle sprain is comparable to MRI.  In this study we evaluated the use of ultrasound in delineating the grade of sprain, with special emphasis of grade 2 sprains.

Methods: We prospectively studied 80 ankle sprains of over two years. All the patients with features of ankle sprain were evaluated with high frequency ultrasound. Grade 1 & 2 sprains were included in the study. All the patients were followed up for 1 year. Grade 2 sprains were treated with cast for 6 weeks and evaluated for any residual symptoms and chronicity.

Results: There were 51 males and 29 females with right ankle injured in 57 patients. Seventy-three patients were injured during their leisure activities and 7 were sports injuries. According to ultrasound grading, there were 58 grade 1 injuries, 22 being grade 2 sprain. All the patients were followed up till 1 year. At the end of one year, 79 patients were recovered well with no residual symptoms.

Conclusions: Ultrasonogram effectively differentiates grade 1 from grade 2 and gives a clue for further management. Therefore, we recommend routine use of ultrasonogram for every ankle sprain. For grade 2 sprains, rigid immobilization for 6 weeks gives excellent results with no residual symptoms.
Dendrimer-paclitaxel complexes for efficient treatment in ovarian cancer: study on OVCAR-3 and HEK293T cells
Authors: Ma Jinqi , Yao Hua
Published: June 2018

The present investigation deal with enhancement the therapeutic effect of Paclitaxel (a potent anticancer drug) by increasing its cellular uptake in cancerous cell with subsequent reduction in its cytotoxic effects.To fulfill the aforesaid purpose the Paclitaxel (PTX)-Biotinylated PAMAM dendrimer complex were prepared using biotinylation method. The primary parameter of Biotinylated PAMAM with terminal HN2 group was evaluated such as degree of biotinylation using HABA assay. The basic integrity of complex was studied using DSC. The Drug loading (DL) and drug release (DR) study of Biotinylated PAMAM dendrimer-PTX complex was also examined. Cellular uptake study was performed in OVCAR-3 and HEK293T cells using fluorescence technique. The statistical analysis was also performed to support the experimental data.The results obtained from HABA assay showed the complete biotinylation of PAMAM dendrimer. DSC study confirmed the integrity of complex when compared with pure drug, biotinylated complex and Physical mixture of both. The batch 9 showed the highest DL (12.09 %) and DR (70 %) up to 72 h when compared by changing concentrations of drug and biotinylated complex. The OVCAR-3(cancerous) cells showed more cellular uptake than HEK293T (normal) cells. The statistical data also supports the experimental results obtained.The results obtained from both experimental and statistical evaluation confirms that the biotinylated PAMAM NH2 dendrimer-PTX complex helps not only in increasing cellular uptake but also increases the release up to 72h with reduction in cytotoxicity.

Brucella abortus S19 strain vaccination is most effectively used as a tool to control the brucellosis in cattle. To understand the genetic basis of differences in immune responsiveness after immunization in cattle of different genotypes, we assessedthe expression of MHC-DRB3 antigen receptor molecule in six each female calves of Karan Fries crossbreds (KF, Bos indicus x Bos taurus) and Sahiwal (Bos indicus) vaccinated with Brucella S19. Serum and peripheral blood mononuclear cells (PBMC) were isolated from blood collected on 0(before vaccination) and 7, 14 and 28 day of vaccination. Antigenic response was assessed for these days in both the groups using Rose Bengal Plate form Test (RBPT). At 0d, the calves of both groups showed no antigen agglutination, confirming the calves free from the infection.The serum of 7d onward started showing the agglutination with more strong response in later stages specifically in KF, indicating increased immune response against Brucella. Therefore, RBPT can be used as earliest screening (7d onward) for Brucella antigenic reactivity in both cattle groups. The expression of DRB3 gene started with slight upregulation after vaccination,in general, however without any significant differences between two different genetic groups upto14d.The significant (p Lass Than 0.01) higher expression (8 times) of DRB3was observed in KF than Sahiwal at 28d. The study indicated that antigenic reactivity and MHC-DRB3 expression elicited by Brucella S19 vaccination was more prominent in KFduring initial days, which may provide an extra advantage to the host for antigen binding, thereby better immune protection at later stage.
Correlation and path analysis for yield and yield attributes in groundnut (Arachis hypogaea L.)
Authors: John K. , Reddy Raghava
Published: June 2018

The estimate of genotypic correlation coefficients in general higher than their corresponding phenotypic correlations indicating strong inherent association among the traits. Pod yield per plant had significant positive association with plant height, shelling per cent and sound mature kernel per cent, while its association with other characters viz., number of mature pods per plant and kernel yield per plant was found to be positive but non-significant. These characters can be considered as criteria for selection for higher yield, as these were mutually and directly associated with pod yield. The maximum positive direct positive effect on pod yield per plant was contributed by kernel yield per plant followed by number of well-filled and mature pods per plant, plant height and sound mature kernel per cent. The high direct effect of pods per plant appeared to be the main factor for its strong positive correlation with pod yield. Hence, a direct selection for this trait would be effective.
Valuing the educational changes in the Romanian educational system

Abstract

 

This research aims to provide an insight into the level of assumption regarding the responsibility of implementing and promoting the educational changes in the Romanian educational system. The diagnosis highlights the need to build an organizational identity, the need for professionalizing the human resources and the orientation towards social values. This research was conducted on a representative sample of teachers in the pre-university education system in the South-East of Romania. It allowed an analysis of the changing phenomenon (of the educational reforms) using scientific methods to obtain information regarding the attitude of the human resource in the educational system towards the educational reform dimensions. This strategy can be considered a support to make the leap to an active portance against educational changes. The respondents realized that, in order to put into practice this goal, the school must activate its mechanisms of strategic management which are meant to lead the educational actors towards a continuously engagement in the development and reconstruction process of school and professionalizing the teaching career.

The effects of Machiavellianism and person–group dissimilarity on workplace incivility
Authors: Ucok Dilek Isilay
Published: June 2018

Workplace incivility is defined as ‘low-intensity deviant behaviour with ambiguous intent to harm the target, in violation of workplace norms for mutual respect’. According to this definition, when the employees act rudely in their social interactions, it lead to some unexpected consequences damaging their employment and work-related issues in organisations. This study investigate the effects of Machiavellianism and person–group dissimilarity on workplace incivility. The data were collected from a total of 185 employees. Questionnaire technique has been used as the data gathering method. In data collection tool, a 7-item Workplace Incivility Scale , 20-item Mach IV Scale and 6-item Perceived Dissimilarity Scale were used. The results indicated that Machiavellianism and person–group dissimilarity have significant positive contributions on workplace incivility. The findings provide evidence that identifying the individual and situational predictors of workplace incivility lead managers to become more aware of hostile working environments and the need to revise their management techniques.

Life satisfaction and real estate living conditions in late adulthood
Authors: Grum Darja Kobal , Grum Bojan
Published: June 2018

The main goal of the research is to investigate the differences in life satisfaction of participants in late adulthood according to their real estate living conditions and care for the elderly. The instruments for measuring the participantsâ€™ views are satisfaction with life scale and real estate living conditions and care questionnaire developed by Grum. A total of 357 participants of age over 65 years took part. The results show that participants who live in rural areas reflect the significantly higher level of life satisfaction than those who live in cities. Older people exhibit high attachment to their property and living environment, which provide them with the higher level of life satisfaction than the possibility of moving to another namely better quality environment. We suggest that housing policy should increase home care in living environment as well as accelerate the intergenerational transmission of real estate in exchange for better home care and coexistence.Keywords: Life satisfaction, real estate living conditions, late adulthood.
Screening for the hyperkinetic disorder by using strength and difficulties questionnaire teacher-report (SDQ-TR) in Indonesia school-aged children
Authors: Siregar Juliarni , Wimbarti Supra
Published: June 2018

The aim of the research was to examine the validity of strength and difficulties questionnaire teacher-report (SDQ-TR) to screen hyperkinetic disorder in Indonesia school-aged children. The SDQ-TR was administrated to the teacher of representative samples of 222 elementary school children (7â€“14 years old). The SDQ-TR hyperactivity-inattention subscale scores were compared with the clinical diagnostic classification from clinical psychologists. The validity of the screening result was analysed using receiver operating characteristic (ROC), likelihood ratio (LR) and Chi-Square. Based on the analysis of ROC and LR by using cutoff point â‰¥ 7, obtained prevalence of hyperkinetic disorder was equal to 34.23% with sensitivity 72.4% and specificity 73.3%. Positive and Negative LR were 2.71 and 0.38. The Chi-Square analysis showed that there was a positive correlation between clinical psychologistsâ€™ diagnosis and the SDQ-TR screening result. The study showed that SDQ-TR was a valid instrument for screen hyperkinetic disorder in Indonesia school-aged children.Keywords: Strengths and difficulties questionnaire (SDQ), hyperkinetic disorder, screening instrument.

Working capital management is germane for the success of the banking industry in Nigeria, especially the current state of the sector, which is engulfed with the effect of the global decline in oil price that has resulted in non-performing loans, deterioration of the bank asset quality, laying-off of staff amongst others. This is one of the reasons why the profitability of the banking sector deeply depends on the efficient management of a bank’s working capital. Therefore, the objective of this study is to examine how profitability of banks can be enhanced through the working capital management. To empirically carry out the analysis, panel data which consist of ten (10) deposit money banks in Nigeria for seven years (2010–2016) employing the panel fixed effect, panel random effect and the pooled OLS for the two models, which were used as proxies for bank profitability, which includes return on asset (ROA) and return on equity (ROE) to examine the best measure for bank profitability, with the indicators of working capital; net interest income, current ratio, profit after tax, and monetary policy rate. Results of the study showed that working capital management has a significant effect on the profitability of the selected banks and that return on asset is a better measure for bank profitability. Therefore, the study recommends that there should be a periodic review of the minimum capital base of the Nigerian deposit money banks so as to mitigate the effects of inflation and inculcate the consequence of time value of money, because the purchasing power of one (₦1) naira or one ($1) dollar today would not be sufficient to purchase what it can purchase today for tomorrow.

Published: June 2018

Multiple factors affect green roof performance and their effects might vary at different stages of operation. This paper aimed to link green roof performance to hydrologic variables (antecedent moisture condition (AMC) and rainfall intensity) and design variables (growing medium (GM) type and depth) under multiple dimensions at the early stage of operation using laboratory experiment data. The results showed that the AMC is the most influential factor of hydrologic performance, whereas the GM type appeared to primarily affect the nutrient levels of the outflow. The significant main effects of other variables and interaction effects between two variables point to challenges in green roof design.

Published: June 2018

Este estudo buscou analisar a percepção dos docentes e pesquisadores brasileiros quanto aos métodos baseados em atividades. Para tanto, foi realizada uma survey com 34 docentes e pesquisadores especialistas em custos dos programas de pós-graduação em Ciências Contábeis no Brasil. Na análise dos resultados foi utilizada a estatística descritiva e empregado o teste de aderência (χ²). A consistência interna do instrumento de pesquisa foi calculada por meio do Alpha de Cronbach o que conferiu consistência ao mesmo. Os resultados demonstram que sob a percepção dos docentes e pesquisadores o Activity Based Cost (ABC) foi capaz de reduzir a subjetividade e arbitrariedade do método por absorção, bem como melhorar as informações para a tomada de decisão. No entanto, o Time-Driven Activity-Based Costing (TDABC) não é considerado de forma unânime uma evolução do método ABC, uma vez que não há uma opinião uníssona se o método foi capaz de reduzir a complexidade e diminuir a necessidade de tempo e recursos relacionados à sua implementação e manutenção. Quanto ao ABM, ele pode ser considerado um sistema de gestão, do qual o ABC constitui sua extensão instrumental.Palavras-chave: Activity-Based Costing. Time Driven Activity-Based Costing.
