Authors: Hashim Rugayah , Ahmad Hashim , Zulkifli Nursyahida , Zainal Bahrin Nur Liyana
Published: March 2017

Family discords or quarrels are considered normal and ordinary. However, the level and intensity of the discords and disputes have led to incidences of fratricide and sororicide. In the case of fratricide (the killing of one’s brother) and sororicide (the killing of one’s sister), the escalating number of incidences as reported in the media requires proper intervention by the relevant parties. The aim of this paper is to review published articles on family discords and violence, particularly on incidences of fratricide and sororicide. The findings and implications of the findings will be discussed in this review paper.Keywords: fratricide; sororicide; discord; family environmentISSN: 2398-4287© 2017. The Authors.

Published: March 2017

Telah dilakukan penelitian untuk mengendalikan laju korosi baja St-37 dalam medium asam klorida dan natrium klorida menggunakan inhibitor ekstrak daun teh (Camelia sinensis). Metode weight loss dan metode potensiodinamik untuk menentukan laju korosi, dalam medium HCl 3 % dan NaCl 3 %, dengan konsentrasi inhibitor yang ditambahkan bervariasi mulai dari 1 % hingga 10 % dengan perendaman selama empat hari. Hasil penelitian menunjukan bahwa laju korosi berkurang dengan meningkatnya konsentrasi inhibitor yang ditambahkan, Peningkatan konsentrasi inhibitor diikuti juga dengan meningkatnya nilai effisiensin inhibisinya. Nilai efisiensi terbesar 86,3 % dengan penambahan konsentrasi inhibitor 10 % untuk medium korosif HCl dan dengan konsentrasi yang sama untuk NaCl mencapai 92,0%.  Analisis morfologi permukaan dengan foto optik memperlihatkan permukaan baja dengan penambahan ekstrak daun teh mengalami korosi  lebih sedikit dibandingkan dengan tanpa inibitor. Hal ini menunjukan bahwa inhibitor ekstrak daun teh sangat efisien untuk mengendalikan laju korosi dalam medium korosif HCl dan NaCl.

 

A research  to control corrosion rate of St-37 steel in acid chloride and sodium chloride medium using tea leaf (Camellia sinensis) extract inhibitor has been done. The method used is potentiodynamic to see the value of the corrosion current and weight loss method for corrosion rate.. Corrosive medium used were HCl 3% and NaCl 3%. The concentration of the extract used range from 1%-10% and the immersion time is four days. The results showed that the corrosion rate was greatest in the corrosive medium without addition of inhibitors, whereas the corrosion rate decreases with the addition of inhibitors, it is also evident from the results of the Tafel plot shows Icor impairment. The greater the concentration of inhibitor that is used the lower the corrosion rate. Greatest efficiency values both for medium corrosive obtained at inhibitor concentrations of 10%, 86,3% in HCl and 92% in NaCl. This shows that tea leaves extract inhibitor is very efficient in controlling the rate of corrosion in HCl and NaCl medium. From the optical photograph  analysed on the surface morphology of St-37 steel showed that the addition of tea leaf extract suffered less corrosion.

Predation of a Western Water Shrew (Sorex navigator) by a Belted Kingfisher (Megaceryle alcyon)
Authors: Jung Thomas S
Published: March 2017

Belted Kingfishers (Megaceryle alcyon) are highly piscivorous and rarely take prey other than fish. Here, I report an observation of a male Belted Kingfisher preying on a Western Water Shrew (Sorex navigator) in a small boreal stream in southwestern Yukon. This observation provides further evidence that Belted Kingfishers will occasionally prey on riparian small mammals when the opportunity arises and points to piscivorous birds as apparently novel predators of shrews.
White-tailed Deer (Odocoileus virginianus) Subsidize Gray Wolves (Canis lupus) During a Moose (Alces americanus) Decline: A Case of Apparent Competition?
Authors: Barber-Meyer Shannon M , Mech L David
Published: March 2017

Moose (Alces americanus) in northeastern Minnesota have declined by 55% since 2006. Although the cause is unresolved, some studies have suggested that Gray Wolves (Canis lupus) contributed to the decline. After the Moose decline, wolves could either decline or switch prey. To determine which occurred in our study area, we compared winter wolf counts and summer diet before and after the Moose decline. While wolf numbers in our study area nearly doubled from 23 in winter 2002 to an average of 41 during winters 2011–2013, calf:cow ratios (the number of calves per cow observed during winter surveys) in the wider Moose range more than halved from 0.93 in 2002 to an average of 0.31 during 2011–2013. Compared to summer 2002, wolves in summers 2011–2013 consumed fewer Moose and more White-tailed Deer (Odocoileus virginianus). While deer densities were similar during each period, average vulnerability, as reflected by winter severity, was greater during 2011–2013 than 2002, probably explaining the wolf increase. During the wolf increase Moose calves remained a summer food item. These findings suggest that in part of the Moose range, deer subsidized wolf numbers while wolves also preyed on Moose calves. This contributed to a Moose decline and is a possible case of apparent competition and inverse-density-dependent predation.
Home Ranges and Movements of Elk (Cervus canadensis) Restored to Southern Ontario, Canada
Authors: Rosatte Rick
Published: March 2017

During 2000 and 2001, Elk (Cervus canadensis) were restored to the Bancroft, Ontario area. The objective of this study was to determine the home range and movements of six social units of Elk, 5–12 years after restoration, in an area of about 2500 km2 near Bancroft. Home range and movements were calculated from 40 221 Global Positioning System locations acquired from 56 collared Elk (16 bulls and 40 cows) between 2006 and 2013. Annual home ranges were found to be significantly greater (mean 110.3 km2, standard error [SE] 11.2) for Elk in areas where winter feeding by humans did not occur compared with those (mean 51.0 km2, SE 9.0) where winter feeding was prevalent. Elk in winter feeding areas had smaller ranges in winter than other seasons. On a seasonal basis, home range size was larger for Elk in areas where winter feeding did not occur; mean winter home range for Elk in non-feeding areas was 73.4 km2 (SE34.0) compared with 8.3 km2 (SE 2.6) for Elk in areas where winter feeding occurred. The 20 Elk that were monitored for multiple years exhibited home range fidelity among years. The entire range of all radio-collared Elk within the social groups studied covered 1716.4 km2 during 2006–2013. Average daily movements of Elk in the study arearanged from 1.0 to 2.1 km/day with greatest movements occurring during spring and summer. However, some Elk were capable of moving an average of 5–7km in a 12-h interval. Movements (about 5 km) to winter range occurred during October to December each year. Cows moved to calving areas in May with mean movements of Elk to spring/summer range about 6 km. Cow/calf groups moved to fall ranges by early September with mean movements of about 4 km. During the rut, mean bull movements of 16.0 km to cow groups over 1–5 days occurred in early September. Hunting of Elk during the fall of 2011 and 2012 did not appear to significantly affect the movements and dispersion of Elk in the study area.
Evidence for Freshwater Residualism in Coho Salmon, Oncorhynchus kisutch, From a Watershed on the North Coast of British Columbia
Authors: Parkinson Eric A , Perrin Chris J , Ramos-Espinoza Daniel , Taylor Eric B
Published: March 2017

The Coho Salmon, Oncorhynchus kisutch, is one of seven species of Pacific salmon and trout native to northeastern Pacific Ocean watersheds. The species is typically anadromous; adults reproduce in fresh water where juveniles reside for 1–2 years before seaward migration after which the majority of growth occurs in the ocean before maturation at 2–4 years old when adults return to fresh water to spawn. Here, we report maturation of Coho Salmon in two freshwater lakes on the north coast of British Columbia apparently without their being to sea. A total of 15 mature fish (11 males and four females) were collected in two lakes across two years. The mature fish were all at least 29 cm in total length and ranged in age from three to five years old. The occurrence of Coho Salmon that have matured in fresh water without first going to sea is exceedingly rare in their natural range, especially for females. Such mature Coho Salmon may represent residual and distinct breeding populations from those in adjacent streams. Alternatively, they may result from the ephemeral restriction in the opportunity to migrate seaward owing to low water levels in the spring when Coho Salmon typically migrate to sea after 1–2 years in fresh water. Regardless of their origin, the ability to mature in fresh water without seaward migration may represent important adaptive life history plasticity in response to variable environments.
Kinetic study of the hydration of propylene oxide in the presence of heterogeneous catalyst
Authors: Akyalcin Sema
Published: March 2017

The kinetics of the hydration of propylene oxide was studied using a pressurized batch reactor for both uncatalyzed and heterogeneously catalyzed reactions. Lewatit MonoPlus M500/HCO3 - was used as heterogeneous catalyst, which showed better performance than Dowex Marathon A/HCO3 -. The effects of the parameters, namely internal and external diffusion resistances, temperature, catalyst loading and mole ratios of reactants, on the reaction rate were studied. The uncatalyzed and heterogeneously catalyzed reactions were proven to follow a series-parallel irreversible homogeneous mechanism. The temperature dependencies of the rate constants appearing in the rate expressions were determined.

Published: March 2017

El curtido del cuero convierte las pieles naturales en materiales flexibles, imputrescibles y duraderos, mediante complejos procesos que generan cantidades significativas de residuos que representan un problema ambiental si no se gestionan adecuadamente. Se presenta una revisión de la literatura sobre la reutilización de residuos sólidos procedentes de las operaciones de procesamiento del cuero. Se encontraron cuatro renglones de investigación ampliamente reportados; en primer lugar, la pirólisis de los residuos para la obtención de combustibles sólidos alternativos y para la síntesis de materiales carbonosos con propiedades multifuncionales, con potencial para el secuestro de dióxido de carbono y para la adsorción de tintes en soluciones acuosas. Los otros tres renglones identificados son la obtención de biodiesel mediante transesterificación, la modificación de asfaltos y el uso de residuos de cuero como material reforzante en mezclas de caucho. La revisión de la literatura indicó que es posible disminuir el impacto ambiental de la industria del cuero, no sólo mediante el tratamiento de efluentes, que ha sido la temática más estudiada, sino tratando los residuos sólidos que se generan durante el curtido para obtener nuevos y valiosos productos.
Bionanocompuestos de quitosano-óxido de grafeno: una alternativa novedosa para la conservación de alimentos
Authors: Grande Tovar Carlos David
Published: March 2017

Los bionanocompuestos son una alternativa emergente de una nueva era de materiales con excelentes propiedades mecánicas, térmicas, de permeabilidad a gases y a la humedad, pero sobre todo, biodegradables y biocompatibles. En la presente investigación se estudió la síntesis de empaques a partir de nanocompuestos de óxido de grafeno-quitosano (CF-GO) y su potencial aplicación en la industria de empaques de alimentos. Los nanocompuestos se prepararon por una reacción térmica de entrecruzamiento entre el quitosano y el óxido de grafeno a 120°C. Las propiedades mecánicas de las láminas obtenidas se estudiaron, de donde se pudo observar que la resistencia mecánica se incrementó desde 22,7 ± 1.2 hasta 6471,6 ± 1775,5 MPa cuando se adicionó 0.1% de GO a las láminas. De igual forma, el incremento en la estabilidad de los empaques se evidenció con el aumento en la estabilidad térmica, evidenciada en el aumento gradual de la temperatura de transición vítrea (Tg) con el aumento de GO. Por último, las propiedades antimicrobianas de las láminas fueron evaluadas contra E. coli K-12 MG 1655 (Gram-negativa) y B. subtilis 102 (Gram-positiva). La lámina CF-GO con 0,6% presentó la mayor inhibición contra E. coli y B. subtilis, con 22,86% y 54,93% de inhibición, respectivamente. De esta manera, la incorporación de GO dentro de las láminas aumentó significativamente la estabilidad térmica y mecánica y adicionó propiedades antimicrobianas, lo cual hace que la aplicación de estas láminas en la conservación de alimentos tenga gran proyección en la industria alimentaria.

Developing indicators for evaluation of age-friendly
communities in Canada: process and results
Authors: Orpana Heather , Chawla M. , Gallagher E. , Escaravage E.
Published: March 2017

Introduction

In 2006, the World Health Organization launched the Global Age-Friendly
Cities Project to support active aging. Canada has a large number of age-friendly initiatives;
however, little is known about the effectiveness and outcomes of age-friendly community
(AFC) initiatives. In addition, stakeholders report that they lack the capacity and tools to
develop and conduct evaluations of their AFC initiatives. In order to address these gaps, the
Public Health Agency of Canada developed indicators to support the evaluation of AFC initiatives
relevant to a wide range of Canadian communities. These indicators meet the varied
needs of communities, but are not designed to evaluate collective impact or enable crosscommunity
comparisons.

Methods

An evidence-based, iterative consultation approach was used to develop indicators
for AFCs. This involved a literature review and an environmental scan. Two rounds of key
expert and stakeholder consultations were conducted to rate potential indicators according to
their importance, actionability and feasibility. A final list of indicators and potential measures
were developed based on results from these consultations, as well as key policy
considerations.

Results

Thirty-nine indicators emerged across eight AFC domains plus four indicators
related to long-term health and social outcomes. All meet the intended purpose of evaluating
AFC initiatives at the community level. A user-friendly guide is available to support and
share this work.

Conclusion

The AFC indicators can help communities evaluate age-friendly initiatives,
which is the final step in completing a cycle of the Pan-Canadian AFC milestones.
Communities are encouraged to use the evaluation results to improve their AFC initiatives,
thereby benefiting a broad range of Canadians.
Indigenous Language Revitalisation and Globalisation

Maketu’s Execution and the Extension of British Sovereignty in New Zealand
Authors: Moon Paul
Published: March 2017

The execution of a minor chief in 1842 in Auckland Prison for the crime of murder would normally be of little significance in the evolution of a nation’s statehood, unless it triggered some form or rebellion or even revolution.  The history of colonial rule in the British Empire in the nineteenth century contains many examples of murderers receiving capital punishment for their crime. However, the constitutional significance of the Governor’s determination to execute the criminal was of substantial, principally because it signified the Crown’s willingness – at this relatively early stage in Crown Colony Government in New Zealand – to extend its jurisdiction so that British law would apply to Maori communities.  Too often, it has been taken for granted that the Treaty of Waitangi asserted (initially in principle and gradually in practice) British sovereignty over Maori as well as Europeans in the country.  However, what the Maketu example illustrates is that the limits of British sovereignty in New Zealand prior to 1842 were confined exclusively to the non-Maori population, as had been the expectation of the Colonial Office in the two years leading up to the conclusion of the Treaty.
Memory, body and dance: a review of literature
Authors: Cleave Peter
Published: March 2017

Distinguishing dance from movement may be a matter of state of mind, of invested meaning. Dance in English seems easy to define but when we get to phrases like 'the dance of desire' or 'we were lead on a merry dance' and when we try and untangle dance from stance or, in some cases, trance and the dance of an eyebrow or a look we need to carefully describe what is going on.
Māori Health: Issues relating to health care services
Authors: Elers Phoebe
Published: March 2017

Since the colonisation of Aotearoa by the British, Māori have experienced health disparities in comparison to non-Māori.  While there have been numerous policies and initiatives to improve the diaspora, this is forecasted to continue for the Māori population.  The source of this health disparity is complex, being embedded in historic and contemporary inequities.  However, one prominent issue which continues to be reported, is the less than adequate health treatment received by Māori in comparison to those of non-Māori or non-Pacific origin.  According to the Ministry of Health, this is adversely contributing to Māori health inequalities. This paper discusses the difficulties confronted by Māori when accessing health care services.

Mana Wahine: Māori Women in Music
Authors: Sheehan Maree
Published: March 2017

Moana Maniapoto and Hinewehi Mohi are famous for having pioneered a distinctively Māori form of popular and political music in the 1990s, and they continue to produce remarkable contemporary waiata for audiences in Aotearoa and overseas. Their successes have inspired other artists, and more importantly, they have both made significant contributions to the empowerment and strengthening of te reo Māori and mātaranga Māori. Recognising what has happened since the 1990s, this paper takes a constructive look at the current state of Māori music and considers how to produce a new wave of creativity for the 21st century for new generations of Māori and Indigenous composers, audiences and performers. How does popular music performance make a powerful contribution to the revitalisation of te reo Māori and mātauranga Māori? Maree Sheehan will lead a conversation with Moana Maniapoto and Hinewehi Mohi to discuss the lasting significance of their work for Māori music and culture, twenty-five years later.
Power and Privilege: The Role of the Reviewer in Responding to Indigenous Theatre
Authors: Joseph Dione
Published: March 2017

Indigenous performance is powerful. While embracing commonalities, it can: dislocate dominant cultural constructions of reality, time and place; interrogate the distinctions between ‘us’ and ‘them’; and carry the ability to refute cultural homogeneity. The latter is especially relevant when applied to critical analyses of Indigenous performance. These are often laced with challenges of power and privilege, for example: varying degrees of cultural awareness; a tendency to blur differences between Indigenous peoples and their creative works; an inclination towards what Rhoda Roberts calls the ‘kindness approach’; and the persistence of Euro-centric aesthetics as the ultimate measure of success. How do reviewers respond to Indigenous performance from positions (real or perceived) of power and privilege, and how are these constructed when framing critical responses? Further, how are these responses complicated when the performance under review is by Indigenous peoples who are not of this place? This paper looks at what happened when HART, an Aboriginal Australian theatre work based on testimonials from the Stolen Generation was reviewed in New Zealand by predominantly Pākehā critics. It also examines how, as reviewers, we can develop a practice of robust criticism that offers an active and engaged response to Indigenous performance and, thereby, empowers the production of Indigenous performance to extend far beyond the walls of the theatre.
MAP Selection Algorithms Based on Future Movement Prediction Capability in Synthetic and Realistic Environment
Authors: Vilhar Andrej , Novak Roman , Kandus Gorazd
Published: March 2017

Efficient mobility management involves micromobilityprinciples. The performance of the Hierarchical MobileIPv6 (HMIPv6) protocol, a representative micro-mobilityapproach, is affected by the Mobility Anchor Point (MAP)selection. In this paper, we propose a new selection method based on a prediction of the future movements of Mobile Nodes (MNs). The proposed algorithms exploit the information about the future availability of MAPs and choose those MAPs that assure a better service. An improvement to the evaluation methodology is also proposed. The algorithms are compared to each other notonly in synthetic but also in realistic internet topologies, which has not been a practice in the past. The simulation results show promising improvements in terms of distance from chosen MAPs and frequency of MAP changes. Moreover, we showed that, for perceivable improvement of MAP selection, absolute accuracy of movement prediction is not required. As pioneers in the mobility management analysis in realistic environment, we ascertain that offering MAP services over more than one Autonomous System (AS) proves beneficial.

OBJECTIVE To determine the prevalence of Alaria infection in cats and dogs in north central Oklahoma over various periods and investigate whether wild animal species in this region were also infected.

DESIGN Combined cross-sectional study and case series.

SAMPLE Results of parasitological testing of fecal samples from 5,417 client-owned dogs and 1,246 client-owned cats (2006 through 2014); fecal samples from 837 shelter or rescue dogs and 331 shelter or rescue cats (2013 and 2014) and 268 feral cats (2015); tongue or jowl samples from cadavers of 43 wild pigs, 3 opossums, and 1 raccoon; and intestinal tract segments from cadavers of 48 cats and 5 coyotes.

PROCEDURES Various parasite recovery techniques were performed to detect various Alaria stages in samples. Recovered adult trematodes and mesocercariae were used for PCR assay and sequencing of the 28S rRNA gene.

RESULTS Prevalence of Alaria infection was significantly higher in feral cats (9.0%) than in shelter or rescue cats (0.6%) and client-owned cats (1.4%) and in shelter or rescue dogs (1.8%) than in client-owned dogs (0.2%). Mesocercariae were recovered from tissue samples from 11 (26%) wild pigs and 1 opossum. Amplicon sequences from adult trematodes and mesocercariae were 100% identical to each other and 99% homologous to GenBank sequences of Alaria alata and Alaria mustelae.

CONCLUSIONS AND CLINICAL RELEVANCE Prevalence of Alaria infection in the study area has increased in dogs and cats since 1990, when infections were rare. Prevalence in wild pigs was similar to that in Eurasia, where A alata is considered an emerging zoonotic parasite.
Intrapericardial cystic hematoma in a dog treated by thoracoscopic subtotal pericardectomy
Authors: Chen Chi-Ya , Fransson Boel A. , Nylund Adam M.
Published: March 2017

CASE DESCRIPTION A 2-year-old castrated male mixed-breed dog was evaluated because of a 1-week history of respiratory distress and abdominal distension. Thoracic radiography and echocardiography at that time revealed an enlarged cardiac silhouette and pericardial effusion; abdominal radiography and ultrasonography revealed ascites.

CLINICAL FINDINGS At the initial referral examination 5 weeks later, the dog weighed 37.5 kg (82.5 lb) and appeared clinically normal. The only abnormality detected was a grade I/VI systolic murmur on the left side of the thorax. Echocardiography revealed a large fat- and fluid-filled cystic structure located next to the right ventricle with scant pericardial effusion. Computed tomography revealed a bilobed peripherally contrast-enhancing structure within the right ventral aspect of the pericardium; the right ventricle appeared compressed by the cyst.

TREATMENT AND OUTCOME Initial treatment consisted of pericardiocentesis and abdominocentesis to alleviate clinical signs. Thoracoscopic subtotal pericardectomy was performed 6 weeks after the initial treatment. The cyst was completely excised, and multiple adhesions between the visceral and parietal pericardium were transected, without surgical or anesthetic complications. Histologic examination of the cyst revealed chronic inflammation with histiocytic infiltration, suggesting possible foreign body reaction or chronic inflammation and hemorrhage. These findings supported a diagnosis of cystic hematoma of the pericardium. The dog remained clinically normal for at least 16 months after surgery.

CLINICAL RELEVANCE This report represents a rare case of intrapericardial cystic hematoma in a dog. Minimally invasive surgery was performed without complications, suggesting that thoracoscopic subtotal pericardectomy is a feasible treatment option for affected dogs.
The Impact of Personality: Extrovert vs. Introvert on the Ability in Syntax in Essay Writing
Authors: Zainuddin Zainuddin
Published: March 2017

The main purpose of this study was to find out if there would be any significant difference in scores for syntax in essay writing between extrovert and introvert EFL learners. The quantitative data were collected by applying writing rubrics from Brown (2007). The participants of this study were 40 English learners (20 extroverts and 20 introverts) at Universitas Negeri Medan, Indonesia. The data were analyzed by using Statistical Package for the Social Sciences (SPSS) version 2.0. The findings of this study indicated that there was a significant difference in the scores for syntax between extrovert and introvert learners. In this study, introvert EFL learners did better than extrovert EFL learners in constructing sentences (syntax). Thus, both groups still have an equal chance to improve their ability in a learning foreign language particularly in writing skills but extrovert EFL learners must pay more attention to using good syntax because they tend to be careless and less correct in constructing their phrases when doing a writing task.
