Tourism in polar regions and the sub-Antarctic islands

Tourism in the Antarctic is coordinated by the International Association of Anrarctica Tour Operators (IAATO) which has regular meetings with the Antarctic Treaty parties. It keeps full records of visitation to the Antarctic and develops guidelines for the conduct of tourist activities so that the needs of tourists, the science community and the Antarctic environment are cared for. The sub-Antarctic has not been a major tourist destination or regulatory focus for IAATO as most sub-Antarctic islands are under national jurisdiction; thus visits to this region are either on the way to or from the Antarctic. Considerable visitation to the sub-Antarctic is conducted by non-IAATO operators. Statistics equivalent to those collected for the Antarctic are not available through IAATO; however, many of the IAATO guidelines are relevant to sub-Antarctic activities. This paper outlines IAATO's history, its guidelines and issues for the future

Sustained Stimulus Paradigms and Sexual Dimorphism of the Aortic Baroreflex in Rat

Indiana University-Purdue University Indianapolis (IUPUI)The neurophysiological pathways associated with beat-to-beat regulation of mean arterial pressure are well known. Less known are the control dynamics associated with short term maintained of arterial blood pressure about a homeostatic set point. The barorefex (BRx), the most rapid and robust of neural refexes within the autonomic nervous system, is a negative feedback controller that monitors and regulates heart rate and blood pressure. By leveraging the parasympathetic and sympathetic divisions of the autonomic nervous system, the BRx can change blood pressure within a single heart beat. To better understand these controller dynamics, a classic BRx refexogenic experimental preparation was carried out. This thesis recon rmed previous observations of an electrically-evoked sexually-dimorphic peak depressor response in the BRx of Sprague-Dawley rats and veri ed that these functional refexogenic differences carry over to sustained electrical paradigms. Further, it uncovered interesting recovery dynamics in both blood pressure and heart rate. The rat aortic depressor nerve was used as an experimental target for electrical activation of the parasympathetic-mediated reduction in mean arterial pressure. The duration, frequency, and patterning of stimulation were explored, with emphasis on differences between sexes. By measuring the normalized percent decrease in mean arterial pressure as well as the differences in beats per minute during rest and during stimulation, the null hypothesis was rejected

Prankster questionaire.

The creative thesis that I have written is a memoir. It is not complete in its detail or ambition but instead focuses on themes and topics of self-transformation, reinvention and the unintentional consequences of several nervous breakdowns and experiments with psychedelic substances. This thesis is just a beginning for a longer more drawn out memoir that will explore the themes above but also discuss family, one’s sense of self worth in the world and how patterns between fathers and sons repeat themselves. I hope to eventually publish this work in a commercial setting

ABSTRAK Mahdaya Landan, No BP 1219842005, Tourism Development Strategy by the Government District of Tanah Datar, Public Administration, Faculty of Socieal Sciences and Political Sciences, Universitas Andalas, Padang, 2018. Supervisor: Rozidateno Putri Hanida, S.IP, M.PA and Ilham Aldelano Azre S.IP, MA. This thesis consists of 171 pageswith references from 10 Theoretical Book, 5 Methodological books, 4 research papers, 1 Rule of District, 2 Documents, and 5 Internet Websites. The purpose of this research is to describe and analyze tourism development strategies used by the Tanah Datar Governmental District. This research is overshadowed by the overhang of serious intent by the Government District of Tanah Datar to increase the economic wellbeing of their community via improvements in the tourism industry, as stated on the RPJMD (Indonesian for: Regional Long-Term Development Plan) of the Tanah Datar District, 2010 – 2015. The objective in developing more potential for the tourism industry is to achieve improvements in regional tourism and in keeping with the visionof the of the Tanah Datar District Department of Cultural Youth Tourism and Sports, "The Establishment of Tanah Datar District as a Tourism Destination with Cultural and Environmental Experiences". The methods used to conduct this study were descriptive qualitative, data were collected by conductinginterviews and documentation. Meanwhile, the data obtained is validated by Triangulation. The selection of informants was done by purposive sampling. This research also implements Robert Crhistie Mill’s theory, which uses a four-way analyzing technique in tourism development that includes Market Analysis, Technical Analysis and Planning, Socioeconomicanalysis and Business and Legal analysis. The results of this study showed that the strategies used by the Government District of Tanah Datar is satisfactory. This is proven by the increase in the number of tourist visits and the expansion of facilities and infrastructure that promotes tourist attraction of the Tanah Datar District. However, problems and obstacles still arise in developing the tourism industry, such as polemic issues on land status or land status locatedon tourist sites, the lack of understanding from the society of the benefits fromthe tourism sector and the absence of legal basis such as RIPPDA (Indonesian for: Regional Tourism Development Master Plan) which specifically regulates the tourism development at the Tanah Datar District.

Development of nano-structured icephobic surfaces based on plasma polymerization

L'accumulation de glace sur les surfaces exposées conduit à des difficultés opérationnelles et des efforts? de maintenance élevés pour les lignes de transport d'électricité, les antennes, les avions, les bateaux et les véhicules de transport terrestre. Dans ce travail, le dépôt de Hexaméthyldisiloxane polymérisé par plasma à basse pression (HMDSO-PP) a été réalisé pour créer des revêtements avec des propriétés superhydrophobes/glaciophobes sur la surface de l'aluminium. Avant de réaliser le revêtement à faible énergie de surface, les surfaces d'aluminium ont été anodisées ou immergées dans de l'eau bouillante pour produire des surfaces micro/nano structurées. Les paramètres du plasma ont été optimisés pour trouver les conditions optimales afin d'obtenir un angle de contact élevé et une faible hystérésis de l'angle de contact. Pour ce faire, la méthode Taguchi-Grey, a été utilisée comme l'une des techniques de conception expérimentale (DOE). La stabilité des revêtements a également été étudiée dans des conditions de vieillissement accéléré tels que la dégradation par UV, l'immersion dans de l'eau distillée, et les solutions avec différents pH, et l'effet de plusieurs cycles de glaçage/de- glaçage. Les résultats obtenus ont montrés que les revêtements PP-HMDSO ont de bonnes stabilités après l'exposition aux rayons UV et après l'immersion dans de l'eau distillée. Toutefois, la propriété de glaciophobe du revêtement PP-HMDSO déposé sur l'aluminium anodisé a été diminuée après quinze cycles de glaçage/de- glaçage. L'étude de l'effet du temps de dépôt de PP-HMDSO ont montré que l'augmentation du temps de dépôt conduit à une diminution de la force d'adhérence de la glace sur un revêtement de PP-HMDSO déposé sur l'aluminium anodisé alors qu'il n'a pas d'effet significatif sur le revêtement PP-HMDSO déposé sur la surface d'aluminium traitée dans l'eau bouillant. Ainsi, le revêtement PP-HMDSO superhydrophobe a également fourni une protection contre la corrosion au substrat d'aluminium. - Accumulated ice on exposed surfaces leads to operational difficulties and extensive maintenance for power transmission lines, antennas, aircraft, ships, and ground transportation vehicles. In the present study, the low pressure plasma polymerized Hexamethyldisiloxane (PP-HMDSO) film is deposited on aluminum surfaces to create a superhydrophobic coating with icephobic properties. Prior to the deposition of this low surface energy coating, aluminum surfaces were anodized or immersed in boiling water to make micro/nano structured surfaces. Plasma parameters were optimized in order to find the best optimum conditions for having high static contact angle and low contact angle hysteresis. Hence, the Grey-based Taguchi method was used as one of the Design of Experiment (DOE) techniques. The stability of coatings was studied under accelerated aging conditions such as UV degradation, immersion in distilled water and different pH solutions, and several icing/deicing cycles. It was observed that the PP-HMDSO coatings are quite stable against UV exposure and immersion in distilled water. However, the icephobicity of the PP-HMDSO coating deposited on the anodized aluminum decreased after fifteen icing/de-icing cycles. The stability of the developed coating was improved against several icing/de-icing cycles by increasing the deposition time of plasma polymerized coating from 15 to 25 minutes. The results showed that increasing the deposition time of plasma polymerization leads to decrease of the ice adhesion strength of coatings on anodized aluminum while it has no significant effect on the PP-HMDSO coating deposited on a water-treated aluminum surface. Finally, the superhydrophobic PP-HMDSO coating also provides anti-corrosion protection for the aluminum substrate

Bone Conduction Audio Communication System for Musicians

poster abstractMusicians often perform their music live with an in-ear device to monitor select audio signals and specific tempos. While wearing conventional earphones as audio monitors enables musicians to coordinate rhythmically, it weakens the user’s awareness to their surrounding acoustic environment by closing off one, if not both ears. Disorientation is common for many musicians, such as saxophonists, violinists, and singers due the inability to fully hear one’s own musical instrument and surrounding ambient environment. This presents the necessity of a better solution for musicians. Bone conduction is an open ear design that allows audio transmission to be heard through vibrations of the bone while allowing the ambient sound of a stage environment to be heard by live performers. Bone conduction, as a means of audio transmission, is a method of sonic communication already shown of value. It is currently implemented in hardware produced by the military and law enforcement. Unfortunately, military oriented products and solutions are not readily available or adaptable to the on-stage performance. Hence, designing a peripheral device specific for live musicians is needed. In our model/research, actual transmission of conducting signals was done with a BCE-1 22x 14mm bone conducting exciter in conjunction with a CBL ASSY 3.5mm slim adapter and ample THHN building wire. The adapter was soldered onto the exciter, which may be powered through the 3.5 mm output of user defined signal generating device of the user’s preference. Future testing of the device will be performed and ultimately used in live performance during one of Dr. Robin Cox’s ensemble rehearsals in the IUPUI Department of Music & Arts Technology

Thermodynamic Properties of Chromium Adsorption by Sediments of River Watari, Kano State

The adsorption of Chromium from aqueous solution using river Watari sediment as an adsorbent was modeled. The influence of initial pH, solution temperature, adsorbent and adsorbate concentrations on the adsorption efficiency was investigated using batch equilibrium assays. From the results obtained for the adsorption envelop experiments, a good adsorption potential was recorded at initial pH of 2 and a temperature of 25oC. The experimental data obtained was subjected to different adsorption isotherm models including; Linear, Langmuir, Freundlich and Temkin to establish the mechanism of chromium adsorption onto the sediment. Amongst the four models tested, Langmuir gave the best fit with regression values ranging from 0.6494 to 0.7459 for 25oC, 30oC, 40oC and 50oC respectively which suggests a homogeneous surface for the sediment. The isosteric heat (ΔHr) of adsorption and enthalpy change (ΔH) did not change with temperature also indicating a homogeneous sediment surface. Based on the values of entropies, activation energies and Gibb’s free energies obtained, the adsorption was found to be spontaneous at all temperatures.Keywords: Adsorption, Chromium ion, Equilibrium isotherms, and Sediment
