Optimal path shape for range-only underwater target localization using a Wave Glider

Underwater localization using acoustic signals is one of the main components in a navigation system for an autonomous underwater vehicle (AUV) as a more accurate alternative to dead-reckoning techniques. Although different methods based on the idea of multiple beacons have been studied, other approaches use only one beacon, which reduces the system’s costs and deployment complexity. The inverse approach for single-beacon navigation is to use this method for target localization by an underwater or surface vehicle. In this paper, a method of range-only target localization using a Wave Glider is presented, for which simulations and sea tests have been conducted to determine optimal parameters to minimize acoustic energy use and search time, and to maximize location accuracy and precision. Finally, a field mission is presented, where a Benthic Rover (an autonomous seafloor vehicle) is localized and tracked using minimal human intervention. This mission shows, as an example, the power of using autonomous vehicles in collaboration for oceanographic research.
Additive Manufacturing of High-Entropy Alloys: A Review

Owing to the reduced defects, low cost, and high efficiency, the additive manufacturing (AM) technique has attracted increasingly attention and has been applied in high-entropy alloys (HEAs) in recent years. It was found that AM-processed HEAs possess an optimized microstructure and improved mechanical properties. However, no report has been proposed to review the application of the AM method in preparing bulk HEAs. Hence, it is necessary to introduce AM-processed HEAs in terms of applications, microstructures, mechanical properties, and challenges to provide readers with fundamental understanding. Specifically, we reviewed (1) the application of AM methods in the fabrication of HEAs and (2) the post-heat treatment effect on the microstructural evolution and mechanical properties. Compared with the casting counterparts, AM-HEAs were found to have a superior yield strength and ductility as a consequence of the fine microstructure formed during the rapid solidification in the fabrication process. The post-treatment, such as high isostatic pressing (HIP), can further enhance their properties by removing the existing fabrication defects and residual stress in the AM-HEAs. Furthermore, the mechanical properties can be tuned by either reducing the pre-heating temperature to hinder the phase partitioning or modifying the composition of the HEA to stabilize the solid-solution phase or ductile intermetallic phase in AM materials. Moreover, the processing parameters, fabrication orientation, and scanning method can be optimized to further improve the mechanical performance of the as-built-HEAs.
The Effects of Human Factors on the Use of Avatars in Game-Based Learning: Customization vs. Non-Customization

ABSTRACT The customization of avatars can help students immerse themselves in game-based learning. However, different individuals have distinct characteristics, especially game experience (GE) and cognitive styles, which may lead to different preferences for the customization of avatars. Thus, this study aims to investigate how GE and cognitive styles affect students’ reactions toward customizable avatars. Two studies, quantitative and qualitative, were conducted for system evaluation. A total of 82 students participated in Study One, where they interacted with both a customizable avatar and an ordinary avatar. The findings from Study One indicated that the students using the customizable version experienced a stronger sense of presence and flow experience than those who used the ordinary version. Regarding GE, the low GE students showed an enhanced sense of presence whereas the high GE students expressed deeper engagement. Regarding cognitive styles, Pask’s Holism/Serialism was adopted. Holists experienced an enhanced feeling of presence whereas Serialists showed deeper engagement. On the other hand, Study Two was conducted with a qualitative approach, where 11 students were further interviewed. The results showed that GE considerably affected their reactions, in terms of favored preferences and engagement, whereas cognitive styles did not have great effects. Based on the findings, a design framework was proposed for the development of personalized game-based learning systems in the future.

Antigastric Ulcer Effect of Turmeric in Rats

Background: Dry powdered rhizome of Curcuma longa, turmeric or Kha-min (in Thai word), was claimed to have antiulcerogenic effect. However, the scientific evidences showing the effectiveness of turmeric in the treatment of gastric ulcer are still controversy. In order to elucidate the antipeptic activity of turmeric, therefore, we investigated the antiulcerogenic effect of turmeric powder and curcuminoid against indomethacin and hypothermic-restraint stress induced gastric ulcer in rats. Methods: Male Wistar rats weighing 180-220 g were used. Gastric lesion was induced by administration of indomethacin 12 mg kg -1 subcutaneously and also by hypothermic-restraint stress. In the study of protective effect, the rats were pretreated with turmeric suspension in 10% propylene glycol orally at doses of 0.25, 0.5 or 0.75 g kg -1 for 3 days. In the investigation of healing effect, the gastric ulcer was induced and followed by administration of turmeric suspension or curcuminoid. Total length of gastric lesion was measured under the stereomicroscope and used as gastric ulcer indicator. Determinations of soluble and insoluble gastric mucus were performed by spectrophotometry method. Results: Turmeric at dose of 0.5 g kg -1 was not only significantly effective in protecting but also enhancing healing of gastric ulcer induced by indomethacin 12 mg kg -1 . Interestingly, turmeric at 0.75 g kg -1 had no antiulcerative effect, and showed a tendency to increase the severity of lesion as compared to control. The curcuminoid 5 mg kg -1 did not show any healing effect in indomethacin-induced ulcer but could significantly inhibit the gastric secretion of soluble mucus at 3.5 hr after curcuminoid administration. Conclusions: It may be concluded that Curcuma longa is effective in protecting indomethacin induced gastric ulcer and enhancing the healing of ulcer. This effect is dose dependent, and can be achieved only with proper dose. Key words: Curcuma longa, Turmeric, Gastric Ulcer, Kha-min

Effectiveness of different denture cleansing methods on removal of biofilms formed in vivo

Background: Denture plaque has been shown to be responsible for a variety of soft tissue changes in many denture wearers. Proper routine cleaning of tissue surface of denture is essential to maintain healthy supporting tissue. Aims: The aim of the present study was to evaluate the effectiveness of different denture cleansing methods i.e., mechanical, chemical and combination method, in removal of plaque from the tissue surface of the denture. Materials and Methods: A total of 50 maxillary dentures in healthy edentulous patients were cleaned randomly with either denture brush, denture cleansing tablet, vinegar, denture cleansing tablet followed by brushing and vinegar followed by brushing. At the test session, every denture with 48 hours accumulated plaque on the tissue surface, was disclosed with a two-tone plaque disclosing agent before and after cleaning the denture and the accumulated plaque was scored according to plaque index. Results: The mean difference of the pre- and postcleansing plaque score was statistically significant ( P < 0.001) for all treatment methods. The plaque removing effectiveness was found to be significantly greater with combination method followed by mechanical and chemical methods. Vinegar was shown to be least efficacious as a denture cleanser. Conclusion: Results of present study suggests that combination of brushing and alkaline peroxides should be encouraged to ensure efficient cleansing of dentures.
Spontaneous Intracranial Hemorrhages in Children

This article reviews a number of intracranial lesions that cause nontraumatic hemorrhages in the pediatric population. Most of these lesions include vascular malformations such as arteriovenous malformations, intracranial aneurysms, and cavernous malformations. Even though other lesions such as vein of Galen malformations, moyamoya disease, and intracranial bleeds associated with tumors are less common, they must be considered in children presenting with nontraumatic hemorrhages. We discuss the differences in presentation and evaluation of these lesions and advocate multidisciplinary management involving neurosurgery, radiosurgery, and interventional neuroradiology.
Saudi Dialects: Are They Endangered?

Krauss, among others, claims that languages will face death in the coming centuries (Krauss, 1992). Austin (2010a) lists 7,000 languages as existing and spoken in the world today. Krauss estimates that this figure could come down to 600. That is, most the worldâ€™s languages are endangered. Therefore, an endangered language is a language that loses her speakers within a few generations. According to Dorian (1981), there is what is called â€œtipâ€ in language endangerment. He argues that a languageâ€™s decline can start slowly but suddenly goes through a rapid decline towards the extinction. Thus, languages must be protected at much earlier stage. Arabic dialects such as Zahrani Spoken Arabic (ZSA), and Faifi Spoken Arabic (henceforth, FSA), which are spoken in the southern region of Saudi Arabia, have not been studied, yet. Few people speak these dialects, among many other dialects in the same region. However, the problem is that most these dialectsâ€™ native speakers are moving to other regions in Saudi Arabia where they use other different dialects. Therefore, are these dialects endangered? What other factors may cause its endangerment? Have they been documented before? What shall we do? This paper discusses three main different points regarding this issue: language and endangerment, languages documentation and description and Arabic language and its family, giving a brief history of Saudi dialects comparing their situation with the whole existing dialects. Then, it shows the first hints of the decline providing the main reasons which may lead to the dialectsâ€™ death.
Behavior surveillance survey amongst truck drivers regarding HIV/AIDS -

Abstract Background: India has one of the largest road networks in the world and an estimated 5 million long distance lorry drivers. These men are away from their families for long durations, and in the unhealthy environment along the highways they become easy prey for commercial sex workers. Methods: This study is based on information collected from a sample survey of long-distance truck drivers and their assistants by pre -coded questionnaire administered to each respondent in a face-to-face interview. Result: In our study 73.3 % truckers were in 21-40 age group. 77 % truckers were married. 95.1 % truckers have heard name of HIV/AIDS. The truckers generally knew that HIV could be transmitted by infected needles /blood transfusion (90.8%) or from sexual route (88.0 %), or from mother to child during pregnancy (65.8 %). However 15.1 % of the men thought mosquito bites could transmit HIV and 5.3 % believed that one could get infected by sharing meals. Almost one-third (26.1%) reported intercourse with at least one \'commercial\' partner (partner with whom sex was exchanged for money) in last 3 months. Though 75.0 % truckers knew that HIV can be prevented by use of condom, only 70.3 %( Out of sexual promiscuous) used a condom while having sexual intercourse with a commercial partner. Conclusion: The study highlights high-risk behavior of long distance truck drivers inspite of having knowledge regarding route of transmission and prevention of HIV. The HIV/AIDS prevention projects in truck drivers should focus on behaviour change and enhancing condom use both with commercial and casual partners.
Literacy and computers: The complications of teaching and learning with technology

Computers, this new collection of essays suggests, are transforming texts, language, and literacy itself. In easy-to-understand language, Literacy and Computers discusses computer-related issues within several larger contexts: the politics, social implications, and economics of literacy education; the roles of authors and readers; the nature of interpretation and subjectivity; and the ways in which human beings construct meaning. The first three parts of the volume examine -- how computers have become part of the classroom -- how electronic networks function as tools for reading, writing, and interpreting texts -- how hypertext, a specialized genre of computer programs, relates to traditional notions of text The fourth part pulls together the multiple voices of the previous contributions and urges readers to venture beyond early studies of computers in composition classrooms. Addressed to novice and expert computer users alike, Literacy and Computers describes the possibilities -- and the difficulties -- posed by the new technologies.
Evaluation of Cardiovascular Activity of an Ayurvedic Product Mrityunjay in Rat Model

Ayurvedic system of medicine is a major component of indigenous systems of medicine in Bangladesh. We used an Ayurvedic drug ‘Mrityunjay’ which is traditionally used for high blood pressure, heart diseases and heartquake. We measured the electrocardiographical (ECG) parameters using an ECG machine (Vet 300, EDAN, China) in rat model before and after administration of the test drug. We observed that, Mrityunjay at high doses (800 μg/Kg, 1600μg/kg, 3200μg/kg) produced heart blocks and other arrhythmias, but in normal dose (200μg/Kg) it has no serious untoward effects on cardiac muscle.

Cervical cancer screening and perceived information needs

Purpose – To identify women's sources of information about cervical cancer screening, information which women report receiving during Pap consultations, information they would like to receive, and the relationships between perceived information needs, personal characteristics and information sources.Design/methodology/approach – Logistic regression analysis of questionnaire data obtained from 408 screen‐eligible women resident in east central UK.Findings – Programme documentation and the Pap consultation represent the main sources of information, although a sizeable proportion rely on other sources (e.g. mass media). The range and frequency of information services which women report receiving during their Pap consultations are variable, and around one‐sixth of women report never receiving information. “Always wanting information” is predictable from subject characteristics, which do not map precisely, owing to the variation in frequency of information being supplied. Age and women's main sources of inform.
