The physical processes of indirect combustion noise generation
Authors: Tam Christopher KW , Parrish Sarah A
Published: February 2018

It is known that a uniform compressible flow supports three types of disturbances. One is entropy wave. These waves are made up of temperature and density fluctuations only. The other two are acoustic waves and vorticity waves. When entropy waves are convected into a nonuniform flow region, they are no longer independent waves. Their presence leads to pressure fluctuations, which result in noise radiation commonly referred to as indirect combustion noise. In the past, because entropy waves and acoustic waves are not independent waves in a nonuniform flow region, the mechanism responsible for the generation of indirect combustion noise had been attributed to mode coupling. That is, there is a coupling of entropy and acoustic modes. This leads to pressure fluctuations and hence noise radiation. The principal objective of the present investigation is to seek a more physical explanation of how indirect combustion noise is generated.
Near-field pressure waveform analysis of an excited Mach 0.9 jet
Authors: Kuo C-W , Crawley M , Cluts J , Samimy M
Published: February 2018

This work explores the effects of axisymmetric, helical, and flapping mode perturbations over a range of Strouhal numbers on the near-field pressure of an axisymmetric Mach 0.9 jet with a Reynolds number of 6.2 × 105. Excitation is generated by eight localized arc filament plasma actuators uniformly distributed around the nozzle exit. The excitation of jet shear layer instabilities resulted in large-scale structures. The signature of these structures in the irrotational near field appears as high-amplitude hydrodynamic pressure fluctuations with wavepacket-like growth, saturation, and decay. The excitation Strouhal number and, perhaps more importantly, the azimuthal mode, are seen to strongly affect the spatial evolution of the wavepacket in both axial and radial directions. The dominant excitation Strouhal number is around 0.3, and the most significant effect on the jet statistical properties (such as distributions of velocity and pressure) occurs further downstream for the flapping mode in comparison to the axisymmetric mode. Dynamic mode decomposition is performed to further describe the modal behavior and evolution of hydrodynamic pressure fluctuations. The pressure response in the near field of jet plumes in flapping mode excitation is shown to exhibit two azimuthal mode behaviors: axisymmetric and flapping. An empirical model of hydrodynamic pressure distribution is established with normalized axial and radial profiles. The amplitude and distribution of the hydrodynamic pressure component are well depicted by the empirical reconstruction.
Unsteady velocity measurements of model-scale supersonic exhaust jets in military-relevant configurations
Authors: Hromisin Scott M , Powers Russell W , Myers Leighton M
Published: February 2018

Of the utmost importance is the need to better understand the high temperature, high velocity flow fields generated by military tactical aircraft during “run up” and take-off that gives rise to extremely hazardous conditions for personnel and equipment within the vicinity of the aircraft. The present study aims to fill the need for high frequency, two velocity component measurements throughout the flow fields produced by university-scale supersonic jets exhausting from nozzles in configurations relevant to practical, full-scale application. Specifically, this work focuses on studying the supersonic jets operating in two basic configurations: horizontal, free jets and jets impinging normal to a ground plane reminiscent of current short-takeoff and vertical landing aircraft. Experiments are conducted at nozzle operating conditions similar to those of full-scale aircraft. Both mean velocities and turbulence components are measured in both flow fields using a laser Doppler velocimeter. Axial components of the mean flow and turbulence are measured in the free jet. In the single impinging jet flow field two-component mean velocity and turbulence components are measured in the jet plume, impingement region, and outwash flow. Free jet velocity measurements show good consistency with 50% increase in jet Reynolds number. Turbulence intensities up to 15% of the mean jet exit velocity are observed at the nozzle exit plane. Laser Doppler measurements in the outwash of an impinging jet show turbulent fluctuations produce unsteady velocities well above the mean value. Two-component impinging jet unsteady velocity spectra show a distinct peak at the same frequency as the impingement tone observed in prior impinging jet acoustic field measurements.
Low-dissipation low-dispersion explicit Taylor-Galerkin schemes from the Runge-Kutta kernels
Authors: Najafiyazdi Mostafa , Mongeau Luc , Nadarajah Siva
Published: February 2018

A multi-stage approach was adopted to investigate similarities and differences between the explicit Taylor-Galerkin and the explicit Runge-Kutta time integration schemes. It was found that the substitution of some, but not all, of second-order temporal derivatives in a Taylor-Galerkin scheme by additional stages makes it analogous to a Runge-Kutta scheme while preserving its original dissipative property for node-to-node oscillations. The substitution of all second-order temporal derivatives transforms Taylor-Galerkin schemes into Runge-Kutta schemes with zero attenuation at the grid cut-off. The application of this approach to an existing two-stage Taylor-Galerkin scheme yields a low-dissipation low-dispersion Taylor-Galerkin formulation. Two one-dimensional benchmarks were simulated to study the performance of this new scheme. The reverse process yields a general approach for transforming m-stage Runge-Kutta schemes into ( m−1)-stage Taylor-Galerkin schemes while preserving the same order of accuracy. The dissipation and dispersion properties for several new Taylor-Galerkin schemes were compared to those of their corresponding Runge-Kutta form.

EFFORT-D study process evaluation: challenges in conducting a trial into the effects of running therapy in patients with major depressive disorder
Authors: Kruisdijk Frank , Hendriksen Ingrid , Tak Erwin , Beekman Aart-Jan , Hopman-Rock Marijke
Published: February 2018

Background

Exercise is currently seen as an effective treatment for major depressive disorder (MDD). However, existing studies have focused mainly on mild-to-moderate depression. The moderate positive effect of exercise found in meta-analyses concerning these studies differs, however, from the harsh daily clinical practice, when trying to implement exercise as an adjunctive treatment. We aimed to evaluate the feasibility of aerobic exercise in MDD and identify future problems for implementation.

Methods

The EFFect Of Running Therapy on Depression (EFFORT-D) study was a randomized clinical trial examining the effectiveness of running therapy or Nordic walking in inpatients and outpatients with MDD. We conducted a process evaluation based on the method of Linnan and Steckler. Participant inclusion, dropout and no show were registered qualitatively and quantitatively.

Results

The inclusion and delivered dose of the exercise interventions were limited (60 and 75%, respectively), leading to 80% less inclusion than foreseen. Motivational doubts were the main reason not to participate in the study. The unexpected high dropout rates (40% after 3 months and 80% after 12 months) were frequently related to lack of motivation due to disease characteristics and severity. The duration of the intervention, longer than 3 months was another underlying factor for poor adherence.

Conclusions

Depression severity appeared to be the key factor determining dropout, followed by the duration of exercise intervention, expressed by a pre- and post-inclusion lack of motivation. Both running therapy and Nordic walking were apparently unsuitable for most patients with MDD in the current format. Emphasis on motivational issues is necessary from the early start of the intervention in these patients with MDD. Also a tailored and stepped-care approach is advised for future implementation.

Trial registration The randomized controlled trial protocol of EFFORT-D was approved by the Medical Ethical Committee for Mental Health (Metigg Kamer Noord), CCMO (Central Committee on Research Involving Human Subjects) Protocol Number: NL.26169.097.08. Registration in the Netherlands Trial Register (NTR): NTR1894 on July 2, 2009

Current issues in veterinary transfusion medicine
Authors: Jones Alice
Published: February 2018

Human and veterinary transfusion medicine is an area where there has been ongoing research and new developments. The way in which blood and transfusion products have been used has been questioned resulting in changes in their use and storage. In transfusion medicine, not only the research methods, but sometimes the application of the product itself, has raised ethical and moral questions, which has in part led to major differences between UK and US transfusion practices. Within the UK there is a rapidly growing demand for banked blood products and an increasing use in practice of both banked products and emergency whole blood donations. Registered veterinary nurses (RVNs) are now able to undertake further qualifications in emergency and critical care which includes the use of blood products. It is of vital importance for the RVN to keep up to date with current thinking on transfusion medicine and to ensure that transfusion guidelines and protocols within their work-place are up to date and evidence based.
Antibiotic resistance in small animal veterinary practice: veterinary nurses as antibiotic guardians
Authors: Hutton Rhiannon
Published: February 2018

Antibiotic resistance is a challenge faced interconnectedly by the veterinary and human medical professions. The veterinary hospital is an environment where infectious agents are under continuous antibiotic pressure and can provide a reservoir for multi-drug resistant bacteria. The development of antibiotic resistance can only be minimised by utilising a multi-factored approach, ensuring that antibiotics are used appropriately, promoting a holistic approach to animal health to help negate the need for antibiotics and implementing effective biosecurity policies to prevent the spread of resistant organisms.
Rabbit health practices of 202 rabbit owners
Authors: Dalley Florence , Oxley James A , Montrose V Tamara , Wills Alison P , Williams Jane
Published: February 2018

Aim:

Owners often underestimate the management needs of pet rabbits. Determining rabbit owners' health management practices, and where they gain healthcare information, will facilitate veterinary professionals in providing advice to rabbit owners.

Method:

Rabbit owners in the UK (n=202) completed an online questionnaire providing information on health checking, vaccination and parasite control practices. Where owners gain information on rabbit health care was also determined.

Results:

The majority of owners performed daily health checks of their rabbit's appetite, posterior, skin, faeces, face and behaviour; weekly checks of their coat; monthly checks of teeth and occasional checks of bodyweight and gums. Most owners had vaccinated their rabbits against myxomatosis and rabbit haemorrhagic disease but were not using parasite prevention methods. The majority of owners stated that they would respond promptly to seek veterinary assistance in response to inappetance. Owners preferred to obtain health information from veterinary professionals, though suggested more information on digestive problems and dental disease would be useful.

Conclusion:

Greater education of owners on the appropriate frequency of health checking is warranted. Veterinary practices could play an integral role in improving owner knowledge of rabbit health practices via providing leaflets in centres, information on veterinary centre websites, and dedicated rabbit clinics.
Maximizing the fixation strength of modular components by impaction without tissue damage
Authors: Krull A. , Morlock M. M. , Bishop N. E.
Published: February 2018

Objectives

Taper junctions between modular hip arthroplasty femoral heads and stems fail by wear or corrosion which can be caused by relative motion at their interface. Increasing the assembly force can reduce relative motion and corrosion but may also damage surrounding tissues. The purpose of this study was to determine the effects of increasing the impaction energy and the stiffness of the impactor tool on the stability of the taper junction and on the forces transmitted through the patient’s surrounding tissues.

Methods

A commercially available impaction tool was modified to assemble components in the laboratory using impactor tips with varying stiffness at different applied energy levels. Springs were mounted below the modular components to represent the patient. The pull-off force of the head from the stem was measured to assess stability, and the displacement of the springs was measured to assess the force transmitted to the patient’s tissues.

Results

The pull-off force of the head increased as the stiffness of the impactor tip increased but without increasing the force transmitted through the springs (patient). Increasing the impaction energy increased the pull-off force but also increased the force transmitted through the springs.

Conclusions

To limit wear and corrosion, manufacturers should maximize the stiffness of the impactor tool but without damaging the surface of the head. This strategy will maximize the stability of the head on the stem for a given applied energy, without influencing the force transmitted through the patient’s tissues. Current impactor designs already appear to approach this limit. Increasing the applied energy (which is dependent on the mass of the hammer and square of the contact speed) increases the stability of the modular connection but proportionally increases the force transmitted through the patient’s tissues, as well as to the surface of the head, and should be restricted to safe levels.

Staphylococcal enterotoxin C2 promotes osteogenesis of mesenchymal stem cells and accelerates fracture healing
Authors: Wu T. , Zhang J. , Wang B. , Sun Y. , Liu Y. , Li G.
Published: February 2018

Objectives

As one of the heat-stable enterotoxins, Staphylococcal enterotoxin C2 (SEC2) is synthesized by Staphylococcus aureus, which has been proved to inhibit the growth of tumour cells, and is used as an antitumour agent in cancer immunotherapy. Although SEC2 has been reported to promote osteogenic differentiation of human mesenchymal stem cells (MSCs), the in vivo function of SCE2 in animal model remains elusive. The aim of this study was to further elucidate the in vivo effect of SCE2 on fracture healing.

Materials and Methods

Rat MSCs were used to test the effects of SEC2 on their proliferation and osteogenic differentiation potentials. A rat femoral fracture model was used to examine the effect of local administration of SEC2 on fracture healing using radiographic analyses, micro-CT analyses, biomechanical testing, and histological analyses.

Results

While SEC2 was found to have no effect on rat MSCs proliferation, it promoted the osteoblast differentiation of rat MSCs. In the rat femoral fracture model, the local administration of SEC2 accelerated fracture healing by increasing fracture callus volumes, bone volume over total volume (BV/TV), and biomechanical recovery. The SEC2 treatment group has superior histological appearance compared with the control group.

Conclusion

These data suggest that local administration of SEC2 may be a novel therapeutic approach to enhancing bone repair such as fracture healing. Cite this article: T. Wu, J. Zhang, B. Wang, Y. Sun, Y.

Published: February 2018

The
purpose of the present study was to investigate whether pre-service
teachers’ cognitive and affective expectations were met after participation of
lab investigations that were designed based on the ADI instructional model. Based
on Novak’ theory of learning, when the students get responsibilities to connect
new knowledge with existing one, the students stand active role in generating
knowledge through experiences. Novak categorized these human experiences as
cognitive (thinking), affective (feeling), and psychomotor (doing). The
successful consolidation of the cognitive, affective and psychomotor
experiences then result in meaningful learning. In order to determine whether
the cognitive and affective expectations of pre-service teachers are fulﬁlled
by their experiences in a science laboratory course, weak experimental design
was utilized in this study. Third grade pre-service science teachers attended
ADI activities as a part of their regular course through 11 weeks. Through ADI
activities pre- service teachers had a chance to engage variety of scientific
activities such as designing investigations, arguing from evidence,
writing scientific reports, and critically evaluating peers' reports. The
results of the study showed that, the ADI instructional model was able to
meet pre-service teachers’ expectations especially in cognitive dimension.

This research was conducted inside the Screenhouse in which located on the top of Griya Kads House building, Bulusan Village, Tembalang Sub-district from May to June 2017. The research was conducted by 3x3 factorial experiments in Nested Design with 3 replications. The first factor was 0, 1.5 and 3 hours irradiation of red and blue LED lights at night. The second factor was 3, 5 and 7 ml/liter of AB mix nutrient concentration which was nested in the first factor. The data collected were fresh weight, dry weight and root canopy ratio. The results of the study showed that the treatment of AB mix nutrient concentration had no significant effect on all parameters. The production of lettuce with level of 5 ml concentration of AB mix was quite good, yet 3 ml and 7 ml levels didn’t improve lettuce production. The duration of red and blue LED irradiation only resulted in an increase in the production of canopy fresh weight.

Authors: Wibisana Andri G.
Published: February 2018

Tulisan ini mendiskusikan perlindungan lingkungan di dalam kerangka keadilan antar generasi.  Tujuan dari diskusi ini adalah memperkenalkan konsep keadilan lingkungan ini, serta untuk menjelaskan bagaimana keadilan antar generasi ini dikaitkan dengan kewajiban seluruh penghuni Bumi atas planetnya (planetary obligations), bagaimana relevansi keadilan dengan valuasi ekonomi, dan bagaimana hubungan keadilan antar generasi dengan hak gugat.  Terkait planetary obligations, tulisan ini menggambarkan keadilan antar generasi sebagai kewajiban antara generasi untuk melakukan perlindungan generasi atas opsi, kualitas, dan akses terhadap sumber daya lingkungan.  Terkait valuasi ekonomi, tulisan ini berpendapat bahwa penggunaan instrumen diskon di dalam penafsiran ekonomi perlu dimodifikasi menjadi diskon yang rendah, sehingga lebih sejalan keadilan antar generasi. Tulisan ini juga mendiskusikan pentingnya putusan Minors Oposa v. Factoran Jr. yang mengakui hak gugat antar generasi.

BEBERAPA PERMASALAHAN PERLINDUNGAN PEKERJA OUTSOURCING BERDASARKAN PERMENAKERTRANS A. Pendahuluan 1. Latar Belakang Penelitian NOMOR 19 TAHUN 2012
Authors: Sonhaji Sonhaji
Published: February 2018

Pekerja/buruh outsourcing mulai dikenal di indonesia sejak berlakunya UU Nomor 13 tahun 2003 tentang ketenagakerjaan, Undang-Undang Nomor 13 Tahun 2003 tentang Ketenagakerjaan tidak menyebutkan secara tegas mengenai istilah dari outsourcing, namun dalam Pasal 64 secara tidak langsung disinggung mengenai outsourcing yaitu “Perusahaan dapat menyerahkan sebagian pelaksanaan pekerjaan kepada perusahaan lainnya melalui perjanjian pemborongan pekerjaan atau penyediaan jasa pekerja/ buruh yang dibuat secara tertulis”.kehadiran perjanjian kerja melalui outsourcing menimbulkan prokontra dikalangan para pelaku proses produksi barang dan jasa. Dikalangan pekerja modal perjanjian tersebut dipandang sangat melemahkan posisi mereka, sedangkan disisi lain pengusaha merasa diuntungkan dengan hadirnya sistem tersebut. Dari kacamata pemerintah sistem outsourcing ada dalam UU yang bari adalah dalam rangka merespon tuntutan kalangan investor khususnya asing.

A Thermal Direct Shear Device for Testing Polymer-Bonded Sands
Authors: Romero Louis , Mendoza Lenny , Nasirian Ali , Cortes Douglas D. , Valdes Julio R.
Published: February 2018

This paper documents the customization of a direct shear apparatus to accommodate heat injection into a polymer-bonded sand (PBS) specimen while in the shear box (i.e., before, during, or after shearing). The system is controlled with an electronic microcontroller that is coded to enable tailored heat treatment protocols and data logging in the temperature range between 110°C and 160°C. The use of the system is exemplified with experiments aimed to characterize the strength of PBS specimens subjected to multiple heating—and thus multiple healing—cycles.
Transcriptional profiling reveals distinct classes of parathyroid tumors in PHPT

Published: February 2018

The clinical presentation of primary hyperparathyroidism (PHPT) varies widely, although the underlying mechanistic reasons for this disparity remain unknown. We recently reported that parathyroid tumors can be functionally segregated into two distinct groups on the basis of their relative responsiveness to ambient calcium, and that patients in these groups differ significantly in their likelihood of manifesting bone disability. To examine the molecular basis for this phenotypic variation in PHPT, we compared the global gene expression profiles of calcium-sensitive and calcium-resistant parathyroid tumors. RNAseq and proteomic analysis identified a candidate set of differentially expressed genes highly correlated with calcium-sensing capacity. Subsequent quantitative assessment of the expression levels of these genes in an independent cohort of parathyroid tumors confirmed that calcium-sensitive tumors cluster in a discrete transcriptional profile group. These data indicate that PHPT is not an etiologically monolithic disorder and suggest that divergent molecular mechanisms could drive the observed phenotypic differences in PHPT disease course, provenance, and outcome.
