description: L'experience, face a la faillite des projets d'hydrauliques villageoises (PHV), a amene les organismes impliques en developpement international a progressivement revoir leur strategie d'aide, en mettant en place d'autres types de structures afin de mieux assurer la participation des populations dans les projets de developpement. Cette participation de la population semble desormais, de plus en plus, reconnue comme condition sans laquelle on ne peut s'assurer de la reussite a long terme des PHV. Considerant que le partenariat est un facteur necessaire, mais insuffisant pour garantir une auto-gestion par la population apres le depart de l'ONG du Nord, nous admettons de par le fait meme, que l'on doit tenir compte d'autres facteurs. Au cours de cette these nous chercherons, entre autres, a identifier ces autres facteurs et a comprendre leurs liens avec le partenariat. Dans le premier chapitre, afin de faire reposer sur des bases solides notre concept central, nous ferons une analyse detaillee du partenariat. Apres avoir explique quelle etait la problematique du sujet, nous identifierons l'evolution et la dynamique du partenariat. La deuxieme partie est essentiellement consacree a l'etude de cas. Nous analyserons en detail le partenariat etabli entre les principaux acteurs du projet de l'hydraulique villageoise au Togo, soit: le CUSO, le gouvernement togolais et les comites de developpement villageois. L'analyse detaillee du projet de l'hydraulique villageoise par CUSO au Togo, nous permettra de scruter, sous de multiples angles, le partenariat et son lien avec l'auto-gestion de projet par les beneficiaires.

description: In this study, membranes were made from three polyvinylidene fluoride (PVDF) polymers individually and the blend systems of high (H) and low (L) molecular weight PVDF by phase inversion process. After investigating membrane casting solutions’ viscous and thermodynamic properties, the membranes so fabricated were characterized by scanning electron microscopy, gas permeation tests, porosity measurement, contact angle (CA) and liquid entry pressure of water (LEPw) measurement, and further subjected to vacuum membrane distillation (VMD) in a scenario that was applicable for cooling processes, where the feed water temperature was maintained at 27℃. It was found that PVDF solutions’ viscosities and thermodynamic instabilities were determined by the types of PVDF employed in single polymer systems and the mixing ratios of two PVDF polymers in blend systems. Thus the membrane properties and performances were influenced by the aforesaid factors as well. In single polymer systems, it was found that the membrane surface roughness and porosity increased with an increase in molecular weight. Among all the membranes casted in this study, the water vapor flux of VMD was found to be the highest at the intermediate range of H:L ratio, i.e., 4:6, at which the thickness of the sponge-like layer showed a minimum, the finger-like macro-voids formed a more orderly single-layer structure, and the LEPw showed a minimum. A conclusion can be made that blend systems of high molecular weight PVDF polymers and low molecular weight PVDF polymers could be used to optimize membrane performance in vacuum membrane distillation.

description: Many educational institutions suffer from a lack of funding to keep telecommunications laboratory classes up to date and flexible. This paper describes our Remote Unix Lab Environment (RULE), a solution for exposing students to the latest Internet based telecommunications software tools in a Unix like environment. RULE leverages existing PC laboratories (often based on Microsoft's Windows) to enable student access to Internet Protocol (IP) networked hosts for telecommunications coursework and research projects. Re-use of existing PC labs substantially decreases the cost of introducing hands on teaching of Unix based Internet services into curricula. We discuss our experiences of deploying, using and provisioning RULE since early 2003. RULE itself is a handful of FreeBSD hosts, mounted in a small back room, utilising FreeBSD's 'jail' functionality to create multiple virtual hosts.

description: Background: Metabolic reprograming, non-mutational epigenetic changes, increased cell plasticity, and multidrug tolerance are early hallmarks of therapy resistance in cancer. In this temporary, therapy-tolerant state, cancer cells are highly sensitive to ferroptosis, a form of regulated cell death that is caused by oxidative stress through excess levels of iron-dependent peroxidation of polyunsaturated fatty acids (PUFA). However, mechanisms underpinning therapy-induced ferroptosis hypersensitivity remain to be elucidated. Methods: We used quantitative single-cell imaging of fluorescent metabolic probes, transcriptomics, proteomics, and lipidomics to perform a longitudinal analysis of the adaptive response to androgen receptor-targeted therapies (androgen deprivation and enzalutamide) in prostate cancer (PCa). Results: We discovered that cessation of cell proliferation and a robust reduction in bioenergetic processes were associated with multidrug tolerance and a strong accumulation of lipids. The gain in lipid biomass was fueled by enhanced lipid uptake through cargo non-selective (macropinocytosis, tunneling nanotubes) and cargo-selective mechanisms (lipid transporters), whereas de novo lipid synthesis was strongly reduced. Enzalutamide induced extensive lipid remodeling of all major phospholipid classes at the expense of storage lipids, leading to increased desaturation and acyl chain length of membrane lipids. The rise in membrane PUFA levels enhanced membrane fluidity and lipid peroxidation, causing hypersensitivity to glutathione peroxidase (GPX4) inhibition and ferroptosis. Combination treatments against AR and fatty acid desaturation, lipase activities, or growth medium supplementation with antioxidants or PUFAs altered GPX4 dependence. Conclusions: Our work provides mechanistic insight into processes of lipid metabolism that underpin the acquisition of therapy-induced GPX4 dependence and ferroptosis hypersensitivity to standard of care therapies in PCa. It demonstrates novel strategies to suppress the therapy-tolerant state that may have potential to delay and combat resistance to androgen receptor-targeted therapies, a currently unmet clinical challenge of advanced PCa. Since enhanced GPX4 dependence is an adaptive phenotype shared by several types of cancer in response to different therapies, our work might have universal implications for our understanding of metabolic events that underpin resistance to cancer therapies.

description: Acute myocardial infarction (MI) is the end result of many cardiovascular diseases and is one of the leading causes of death in the western world. Cell therapy, using circulating angiogenic cells (CACs) or CD34+ cells from peripheral blood, is one approach under investigation for restoring blood flow and function to the ischemic heart. However, the numbers of CACs and CD34+ circulating cells are inversely proportional to the severity of cardiovascular disease and age; therefore, there is a need to increase their numbers and/or function for therapy. One possibility is to enhance the therapeutic potential of the cells with the use of a biomaterial. In this study, we used a collagen matrix to culture human CD34+ circulating cells, and evaluated the effect of the matrix on CD34+ cell properties and function. The matrix was able to successfully increase proliferation, migration, CD34+ phenotype and branching in an angiogenesis assay. These functional benefits may be associated with the sonic hedgehog (Shh) pathway. The collagen matrix was previously shown to enhance the function of healthy CACs, but its ability to do the same for CACs from coronary artery disease patients is unknown. In this study, the matrix was shown to enhance the viability, proliferation and angiogenic potential of patient CACs. Furthermore, gene expression for integrins and Shh pathway components in the sub-population of CD34+ cells was similar between patient and healthy donors when isolated from CACs. This work provides insight into the mechanisms for the observed matrix-enhanced function of therapeutic CACs and CD34+ cells from both healthy and CAD patient donors.

Life on the line: Using diffusion of innovation theory to understand the adoption, spread, and co-adoption of conservation and other environmental initiatives
Creators: name: Lewis-Brown, Emily-Jane
Publisher: name: Imperial College London
Year: 2023

description: Preserving and restoring nature is critical, and conservation initiatives must be adopted and spread effectively at unprecedented rates. However, knowing how to scale-up conservation to meet this challenge remains elusive and understudied. The factors influencing adoption and spread of behaviours and technologies in other fields are well-researched and described through diffusion of innovation theory (hereafter, diffusion theory). Diffusion theory is used to increase the adoption and spread of behaviours and technologies in wide-ranging disciplines. Therefore, this thesis applies this long-standing and well-researched theoretical lens to advance scientific understanding of the diffusion of conservation initiatives. Firstly, I examine what characteristics of Locally Managed Marine Areas (LMMAs) in Madagascar - a community-based conservation initiative - help and hinder their adoption, using choice experiments. I then use customer satisfaction research methods to measure the likely spread of these initiatives. Next, I test for correlations between the adoption of carbon management priorities, policies, practices, and emissions over time. The results support the application of diffusion theory to LMMAs in Madagascar, with some adaptations, as adopters were motivated more by pro-social values than typically reported in diffusion literature. However, adopters reported dissatisfaction with their LMMAs due to negative impacts that may hinder the spread of these conservation initiatives. Finally, I found that adopters of voluntary carbon offsets, co-adopted more carbon management practices than did non-adopters of VCOs, contrasting with some literature, but consistent with diffusion theory literature which describes the effectiveness of co-adopting innovations in mutually re-enforcing clusters. This study contributes new insights into the adoption, spread, co-adoption, and outcomes of conservation and other environmental initiatives that can be used to advance both conservation science and practice to help conservation initiatives reach scale and ensure they do no harm.

description: Kallikrein-related peptidases (KLKs) and matrix metalloproteinases (MMPs) are secretory proteinases known to proteolytically process components of the extracellular matrix, modulating the pericellular environment in physiology and in pathologies. The interconnection between these families remains elusive. To assess the cross-activation of these families, we developed a peptide, fusion protein-based exposition system (Cleavage of exposed amino acid sequences, CleavEx) aiming at investigating the potential of KLK14 to recognize and hydrolyze proMMP sequences. Initial assessment identified ten MMP activation domain sequences which were validated by Edman degradation. The analysis revealed that membrane-type MMPs (MT-MMPs) are targeted by KLK14 for activation. Correspondingly, proMMP14-17 were investigated in vitro and found to be effectively processed by KLK14. Again, the expected neo-N-termini of the activated MT-MMPs was confirmed by Edman degradation. The effectiveness of proMMP activation was analyzed by gelatin zymography, confirming the release of fully active, mature MT-MMPs upon KLK14 treatment. Lastly, MMP14 was shown to be processed on the cell surface by KLK14 using murine fibroblasts overexpressing human MMP14. Herein, we propose KLK14-mediated selective activation of cell-membrane located MT-MMPs as an additional layer of their regulation. As both, KLKs and MT-MMPs, are implicated in cancer, their cross-activation may constitute an important factor in tumor progression and metastasis.

description: Entrepreneurs are encountering a number of constraints pertaining to finance, marketing, technological and export for smooth running of their entrepreneurial units. Therefore, there is urgent need to provide the facilities which facilitate them setting up of economically viable units and they should be equipped with latest technologies and skills by organizing different entrepreneurial motivational and skill oriented programs frequently. With this background the present study was undertaken in the four industrially leading districts of Haryana state to determine the correlates which help in establishing economically viable small scale agro- processing units; to determine the specific training needs of entrepreneurs who have already established their units; to make an assessment of problems encountered by entrepreneurs to facilitate setting up of sustainable units and to suggest the strategies for smooth working of small scale agro-processing units. A total number of 120 entrepreneurs who were running their agro-processing units were constituted the sample for the study.

description: Abstract of the paper (Plant Ecology, https://doi.org/10.1007/s11258-023-01372-8):Plant species of ancient forests tend to be poor dispersers, although field studies suggest that dispersal may be strongly accelerated in streams. To further test this idea we addressed the following two questions: 1) which traits facilitate transport and deposition of seeds by streams? 2) do ancient forest species differ from other forest species with respect to these traits?In the Boven Slinge, a forested lowland stream in the Netherlands we measured seed transport and deposition and analysed which traits best explained this. We subsequently compared ancient forest species with other forest species with respect to these key traits.Our field measurements indicated that stream dispersal is strongly determined by both source related traits, i.e. upstream population size, seed production and seed release period and the path related variables buoyancy and seed weight. These traits seemed to affect transport and deposition similarly, but seed mass had a much stronger, negative impact on deposition.Compared to other forest species ancient forest species do not differ with respect to seed release period, buoyancy and mass, but at a given plant height, ancient forest species produce less seeds than other forest species. This may reflect an adaptation to their relatively stable habitat which comes at the expense of (stream) dispersal capacity. In conclusion, ancient forest plants are just as well equipped for stream dispersal as other forest species, but success will critically depend on upstream population size, given their low per plant seed production.
Neural mechanisms of audio-tactile speech integration

Publisher: name: Imperial College London

description: The ability to understand speech in noisy environments is a remarkable feat of the human brain. It is further enhanced by the capability to integrate information from several modalities. Most notably, audiovisual information improves speech-in-noise comprehension tremendously. Yet, the neural mechanisms underlying this remarkable property remain poorly understood. This is partly due to the complexity of the interactions between speech and visual signals. In contrast, tactile signals can conveniently be designed to transmit simple information targeting specific features of speech. They have also been shown to elicit multisensory activity in the auditory cortex, and thus have the potential to be used as both a neuroscientific tool and a hearing aid. In this thesis, we engineered tactile stimuli with the goals of improving speech-in-noise com- prehension and investigating the neural mechanisms underlying multisensory speech perception. First, we derived tactile pulses from the perceptual centers of syllables and measured their effect on speech comprehension and neural activity. Both measures were modulated according to the alignment between auditory and tactile streams, displaying oscillatory behaviours. Secondly, we measured the effect of rhythmic tactile pulses on a syllable discrimination task. We analo- gously observed oscillations, albeit damped, of both syllable discrimination and neural activity. Finally, we built a spiking neural network using multisensory phase reset to model audio-tactile speech integration. This model consistently reproduced our main results, thus suggesting that multisensory phase reset is a viable mechanisms to explain early audio-tactile speech integration. The proposed work shed lights on the neural mechanisms underlying multisensory speech processing and how they can be leveraged to improve comprehension. It also highlights the possibility to design and use tactile stimuli to investigate specific stages of the speech processing hierarchy.

description: Lower extremity kinematic alterations associated with sport-related knee injuries may contribute to an unsuccessful return to sport or early-onset post-traumatic osteoarthritis. Also, without access to sophisticated motion-capture systems, temporospatial monitoring of horizontal hop tests during clinical assessments is limited. By applying an alternative measurement system of two inertial measurement units (IMUs) per limb, we obtained and validated flying/landing times and hop distances of triple single-leg hop (TSLH) test against motion-capture cameras, assessed these temporospatial parameters amongst injured and uninjured groups, and investigated their association with the Knee Injury and Osteoarthritis Outcome Score (KOOS). Using kinematic features of IMU recordings, strap-down integration, and velocity correction techniques, temporospatial parameters were validated for 10 able-bodied participants and compared between 22 youth with sport-related knee injuries and 10 uninjured youth. With median (interquartile range) errors less than 10(16) ms for flying/landing times, and less than 4.4(5.6)% and 2.4(3.0)% of reference values for individual hops and total TSLH progression, differences between hopping biomechanics of study groups were highlighted. For injured participants, second flying time and all hop distances demonstrated moderate to strong correlations with KOOS Symptom and Function in Daily Living scores. Detailed temporospatial monitoring of hop tests is feasible using the proposed IMUs system.
Lifestyle-related Risk Factors Associated with Alzheimer's Disease: A Systematic Review of the Literature

description: In the absence of curative therapies for Alzheimer’s disease (AD), primary prevention strategies are imperative. As a component of the National Population Health Study of Neurological Conditions, systematic searches of the literature were conducted to identify lifestyle-related risk factors associated with AD. Results of the overview of reviews was suggestive of an association between current smoking, lower social engagement, light-to-moderate alcohol consumption, higher educational attainment, and regular engagement in physically and cognitively stimulating activities with risk of AD. Results of the de novo systematic review indicated that the available evidence was inadequate to suggest an association between stress (i.e. psychological, work-related) and stress indicators (i.e. PTSD, neuroticism) with risk of AD. Too few studies were identified in the updated systematic review on Mediterranean diet adherence to allow for definitive conclusions. Important methodological limitations preclude the development of public health recommendations for primary prevention initiatives.
Laser assisted machining of high chromium white cast-iron
Creators: name: Armitage, Kelly
Publisher: name: Swinburne
Year: 2024

description: Laser-assisted machining has been considered as an alternative for difficult-to-machine materials such as metallic alloys and ceramics. Machining of some materials such as high chromium alloys and high strength steels is still a delicate and challenging task. Conventional machines or computer numerical control (CNC) machines and cutting tools cannot adapt easily to such materials and induce very high costs for operations of rough machining or finishing. If laser-assisted machining can be implemented successfully for such materials, it will offer several advantages over the traditional methods including longer tool life, shorter machining time and reduced overall costs. This thesis presents the results of the research conducted on laser assisted machining of hard to wear materials used in making heavy duty mineral processing equipment for the mining industry. Experimental set up using a high power Nd:YAG laser beam attached to a lathe has been developed to machine these materials using cubic boron nitride (CBN) based cutting tools. The laser beam was positioned so that it was heating a point on the surface of the workpiece directly before it passed under the cutting tool. Cutting forces were measured during laser assisted machining and were compared to those measured during conventional machining. Results from the experiments show that with the right cutting parameters and laser beam position, laser assisted machining results in a reduction in cutting forces compared to conventional machining. A mathematical thermal model was used to predict temperatures within the workpiece at depths under the laser beam spot. The model was used to determine the effect of various cutting and laser parameters on the temperature profile within the workpiece. This study shows that laser assisted machining of hard to wear materials such as high chromium white cast iron shows potential as a possible economical alternative to conventional machining methods. Further research is needed before it can be introduced in industry as an alternative to conventional machining.

description: Non-contact life detection is a significant component of both civilian and military rescue applications. As a consequence, this interest has resulted in a very active area of research. The primary goal of this research is reliable detection of a human breathing signal. Additional goals of this research are to carry out detection under realistic conditions, to distinguish between two targets, to determine human breathing rate and estimate the posture. Range gating and Singular Value Decomposition (SVD) have been used to remove clutter in order to detect human breathing under realistic conditions. However, the information of the target range or what principal component contains target information may be unknown. DFT and Short Time Fourier Transform (STFT) algorithms have been used to detect the human breathing and discriminate between two targets. However, the algorithms result in many false alarms because they detect breathing when no target exists. The unsatisfactory performance of the DFT-based estimators in human breathing rate estimation is due to the fact that the second harmonic of the breathing signal has higher magnitude than the first harmonic. Human posture estimation has been performed by measuring the distance of the chest displacements from the ground. This requires multiple UWB receivers and a more complex system. In this thesis, monostatic UWB radar is used. Initially, the SVD method was combined with the skewness test to detect targets, discriminate between two targets, and reduce false alarms. Then, a novel human breathing rate estimation algorithm was proposed using zero-crossing method. Subsequently, a novel method was proposed to distinguish between human postures based on the ratios between different human breathing frequency harmonics magnitudes. It was noted that the ratios depend on the abdomen displacements and higher harmonic ratios were observed when the human target was sitting or standing. The theoretical analysis shows that the distribution of the skewness values of the correlator output of the target and the clutter signals in a single range-bin do not overlap. The experimental results on human breathing detection, breathing rate, and human posture estimation show that the proposed methods improve performance in human breathing detection and rate estimation.

description: Due to the attractive advantages of wireless communication technologies, wireless networking and mobile computing has developed expeditiously and gained ample prevalence. Thereby, many practical applications are being designed for the use of wireless ad hoc networks in both military and civilian scenarios. However, some security concerns have arisen from such networks, especially in that misbehaving nodes pose a major threat during the construction of a trusted network. Therefore, security is one of the key challenges in wireless ad hoc networks, requiring significant attention due to their own features and concerns. This thesis presents several computational models and security strategies for the design of secure, trustworthy networks, which are able to make rational decisions when encountering potential threats. In this thesis, we first propose a distributed network management model for secure group communication. Our approach simplifies the complexity of traditional group management and supports the inclusion of other security mechanisms for the purpose of secure communications. As a decentralized management method, trust can perform well in a dynamic and agile environment. Our proposed trust system defines the concept of trust, establishes the trust relationship between distributed nodes, involves the novel and effective computational model, and specifies a set of trust-based rules in this system for wireless nodes. We also propose a hybrid cryptosystem through the application of both symmetric and asymmetric key algorithms to provide reliable and secure protection of data confidentiality. With the design of selective encryption, uncertainty is incorporated into data encryption and the overhead spent on the data protection is significantly reduced. Thus, the communicating parties not only obtain reliable security protection, but also improve the efficiency of data communication. Through security analysis and simulation experiments, we have shown how decentralized management is useful in wireless and ad hoc scenarios, how trust provides feasible solutions for misbehavior detection, and how our proposed strategies offer security properties.
Entrepreneurship as the missing factor in sustainable economic development of poor nations: a systematic analysis of factors of production
Creators: name: Anyansi-Archibong, Chi
Publisher: name: Swinburne
Year: 2024

description: Entrepreneurship has been viewed and cited by researchers as an important and key contributor to a nation's industrial development as well as a significant driving force in the nation's economic development (Steward and Boyd, 1988). Economists in the study of factors of production (Exhibit 1) identify entrepreneurship and knowledge as the two most critical of the five factors. In the same trend of argument, a management expert and business consultant, Peter Drucker (1999) declares knowledge as the most important factor giving examples of how the young workers on the high-tech industries of Silicon Valley area of California are often referred to as knowledge workers. It will be argued in this paper that entrepreneurial skills/characteristics include knowledge and the ability to recognize analyze and seize opportunities. Additionally, an analysis (Nickels etal, 2004) of the rich and poor countries to determine what causes the difference in the levels of wealth show that entrepreneurship and knowledge are the most dominant cause of wealth. The analysis indicates that most poor countries have abundance of land, labor, and natural resources (China and Russia as command economies) but lack knowledge and entrepreneurship. In contrast, Japan and Hong Kong for example, are relatively rich countries but are poor in land and Natural resources. It will be argued in this paper that capital could not be the missing ingredient since capital (tools, machinery, etc) could be made available by International Monetary Fund (IMF), World Bank and other funding agencies including the national gorvernments. This paper examines the relationships among the factors of production( land, labor, capital, knowledge and entrepreneurship) and the potential of a country to develop and sustain its economy. The paper argues that entrepreneurship is the most critical and necessary factor for effective economic development. The current globalization process appear to be forcing industrialized nations to find ways to revive entrepreneurial activities in their efforts to reactivate and sustain the economic growth and to compete effectively in the global society.
Double-clad photonic crystal fiber coupler for compact nonlinear optical microscopy imaging

description: A 1×2 double-clad photonic crystal fiber coupler is fabricated by the fused tapered method, showing a low excess loss of 1.1 dB and a splitting ratio of 97/3 over the entire visible and near-infrared wavelength range. In addition to the property of splitting the laser power, the double-clad feature of the coupler facilitates the separation of a near-infrared single-mode beam from a visible multimode beam, which is ideal for nonlinear optical microscopy imaging. In conjunction with a gradient-index lens, this coupler is used to construct a miniaturized microscope based on two-photon fluorescence and second-harmonic generation. Three-dimensional nonlinear optical images demonstrate potential applications of the coupler to compact all-fiber and nonlinear optical microscopy and endoscopy.

description: The passage from the disciplinary society, characteristic of modernity, to the contemporary neoliberal society is accompanied by important changes from the point of view of the psychic economy and, in parallel, of the statute of body. The first part of this article discusses the body emptied of enjoyment, subject to the norms of the disciplinary system – a body excessively determined by the symbolic. The second focuses on the body inflated with enjoyment, urged to construct itself in the line of neoliberal entrepreneurship – a body excessively invested by the imaginary. The third highlights the body flooded with enjoyment of the typical pathologies of our time – a body excessively invaded by the real. / A passagem da sociedade disciplinar, característica da modernidade, à sociedade neoliberal contemporânea é acompanhada de mudanças importantes do ponto de vista da economia psíquica e, paralelamente, do estatuto do corpo. A primeira parte deste artigo aborda o corpo esvaziado de gozo, submetido às normas do regime disciplinar – um corpo excessivamente determinado pelo simbólico. A segunda enfoca o corpo inflado de gozo, instado a construir-se na linha do empreendedorismo neoliberal – um corpo excessivamente investido pelo imaginário. A terceira destaca o corpo inundado de gozo das patologias típicas de nossa época – um corpo excessivamente invadido pelo real.

description: Temporomandibular Disorder (TMD) patients report amplification of pain in the masticatory muscles after psychological trauma or stressful conditions. The mechanisms underlying this phenomenon are yet to be elucidated. This study combined immunohistochemistry with single cell in vivo electrophysiology recordings of masticatory muscle afferent fibers to investigate the role of α₁-adrenergic receptors in muscle nociception. It was found that a subset of trigeminal afferent fibers which innervate the masseter and temporal muscles expressed α₁α, α₁b and α₁d receptors, including a smaller number of putative nociceptors which co-expressed TrpV₁ receptors. Local injection of the selective α₁ adrenergic receptor agonist phenylephrine into masticatory muscle decreased and increased the mechanical activation threshold of slow and fast conducting afferent fibers, respectively. This effect was reversed by co-administration of the α1 selective antagonist terazosin. To rule out the possibility that local ischemia was responsible for the observed effect of phenylephrine on masticatory muscle afferent fibers, additional experiments were conducted where blood flow to the masticatory muscle was reduced by common carotid artery occlusion. This investigation found that muscle blood flow occlusion increased the mechanical activation threshold of the majority of masticatory muscle afferent fibers unrelated to conduction velocity. These findings suggest that under conditions of increased sympathetic tone, such as those related to stress, noradrenaline may sensitize masticatory muscle nociceptors to increase pain and desensitize muscle proprioceptors to alter muscle tone, through activation of α1 receptors.

description: Much information communication technology (ICT) design work involves international collaboration. This requires cross-cultural understandings with one's co-collaborators. There are few opportunities for this to occur in a pedagogical setting. This paper outlines a pedagogically-oriented case study of the use of a 3D collaborative virtual environment (3DCVE). The 3D co-located laboratory (3DCollab) described in this paper served as a cross-cultural exchange platform. It fostered deeper understandings of alternate meanings to everyday social and work practices and design computing assumptions. The project involved students across three cooperating institutions, on three different continents in different time zones. It builds on previous exercises conducted by the authors.
