OBJECTIVE: This study examined intra- and inter-individual variability in upper limb movements of ballet dancers when performing flapping swan-wing movements, and it assessed differences in joint angles of upper limbs between dancers of different skill levels. METHODS: 23 female ballet dancers (3 professional, 6 advanced, and 14 intermediate dancers) and 21 age-matched females without previous dance experience participated in this study. Thirty-three reflective markers were attached to each participant’s trunk and upper limbs, and the flapping upper limb motions from Swan Lake were subsequently captured with eight optical cameras. Peak values of upper limb joint angles (shoulder, elbow, and wrist joint) were obtained, and intra- and inter-individual movement variability of each joint angle were compared between groups. RESULTS: In joint angles of the shoulder, elbow, and wrist, there were few differences among professional, advanced, and intermediate groups. The intra-individual movement variability in upward arm movements was significantly larger for professional and control groups than for advanced and intermediate groups, while in downward arm movement, variability became significantly smaller as technical level increased. Moreover, inter-individual movement variability was larger in the upward arm movement as technical level increased, and smaller in the downward arm movement for the professional group. The results suggested that the upward arm movements reflect dancers’ individual expression, while the downward arm movements reflect their technical competence at this swan-like movement. CONCLUSION: The complicated swan-like movements performed by skilled dancers in this study indicate that they execute expressive and technical components in sequence.

Introduction: Scrub typhus is public health problem in South East Asian Region and also it is of rising concern in India. Eastern part of Maharashtra state is highly vulnerable to the disease as it is under forest cover. This region is presently witnessing outbreak of scrub typhus. The present case control study aims to understand determinants of the scrub typhus in this geographical location. Material & Methods: Operational definition for scrub typhus cases used in present study was “Individuals who are positive for IgM Elisa of Scrub typhus”. Cases of scrub typhus reported to health system that comply with the operational definition were recruited. Individually matched controls were selected from the same village. Matching was done for age, sex, socioeconomic status and residence. Total 16 cases and 32 controls were enrolled and compared for socio-demographic, environmental and behavioral domains. Results: Clinical menifestations among cases were Fever, malaise, headache, escahar and rash. The most common sites of escar was groin 3 (42.8%), followed by suprascapular region 2 (28.6%), axilla 1(14.3%) and elbow 1 (14.3%). The risk factors for scrub typhus were vegetations around household within 3 feet range, length of grass blade more than 2 feet, routine work in shrub, engaging in forest related work and activities aroud lake with the odds 5.41 (1.13-25.83), 5.6 (1.24-25.49), 3.66 (1.04- 12.9) 4.2 (1.02-18.02) and 4.59 (1.25-16.77) respectively. Conclusion: Apart from other known risk factors, present study ascertained activities around lake, closeness of vegetations to the household (less than 3 feet) and length of grass blade (more than 2 feet) as new risk factors. These findings may be helpful in developing targeted intervention strategies to control scrub typhus.

Background: Stand-up paddleboarding (SUP) is a water sport that has gained in popularity. Still, very little is known about its injury profile. Purpose: To analyze the incidence, mechanisms, and risk factors for SUP-related injuries in mainly calm waters and the use of safety equipment. Study Design: Descriptive epidemiology study. Methods: The authors distributed an online survey that gathered information on characteristics, injury history over the past 12 months, use of (safety) equipment, and health issues of SUP riders in German-speaking countries. Results: A total of 438 participants completed the survey. The mean participant age was 45 years (range, 8-82 years), 48% were female athletes, and 19.6% took part in competitions. Over the past 12 months, 72 (17%) of 431 respondents experienced a SUP-related injury, resulting in an overall incidence rate (IR) of 1.95 injuries per 1000 hours of activity. Male competitive athletes using a hardboard had the highest risk of injury. The IR for competitive riders was higher (3.21 injuries per 1000 hours) than that for recreational riders (1.41 injuries per 1000 hours). Mechanisms of injury were overuse (n = 29) and contact with the board (n = 18) or ground (n = 12). Injuries affected mainly muscles/tendons and joints of the upper arm/shoulder (n = 20), followed by wrist/hand (n = 18), knee (n = 16), elbow/forearm (n = 12), and foot (n = 11). The highest risk of injury occurred when paddling in wild water (33.3%), followed by SUP surfing (29.4%), and the lowest risk occurred while paddling on a lake (16.1%). A life vest was always used by 27, depending on the situation by 201, and never by 202 participants; a leash was always used by 161, depending on the situation by 244, and never by 26 participants. Of the 272 participants who paddled in winter, 253 wore a drysuit or wetsuit, whereas 19 paddled without any special clothing. Conclusion: SUP-related injuries predominantly happened in wild water or while SUP surfing, and male competitive athletes using a hardboard had the highest risk of injury. The main mechanisms of injury were overuse and hitting the board or ground. The upper extremity was more prone to injury, followed by the knee and foot. More effort should be made to educate paddlers on the necessity and correct use of the life vest, leash, and specialized outfits.

Abstract Lakes have an important role in hydrological and biochemical cycle. It also has some other crucial role such as domestic and industrial water use as well as irigation. The monitoring and management of this aquatic resources is crucial. But with many numbers of lakes, it is very challenging to manage them all. Clustering lakes can provide the answer so the management of the same cluster lakes may be done efficiently. Within this study, morphometry data of 6 lakes in Kampar Regency, Riau Province, were analyzed by using one of artificial intelligence branch which is machine learning. Morphometrical data are collected by using information geographic system. These data then categorized by using python language. This categorization based on data mining categorization algorithm named K-means. Based on the K-means machine learning clustering, the optimum cluster based on Elbow methid is k=3. But there is a possibility to look around for k=2. Based on K=3, cluster 3 is defined as the lowest values of all atribute. Based on k=2, the lowest value of morphometry data wiil be in the cluster 1.. These data will not only provide basic data such as total area, shape, width and length, but also help to understand the large scale hydrological models.

Background: The lateral humeral condylus fracture in a child can be difficult to diagnose because the bones of a child not ossification yet. This resulted the fracture is difficult to see or even pass in viewing. In management, the lateral humeral condylus fracture in children has controversy, between non-operative and operative (especially in fracture with minimal displace). This case report discusses the case of the humeral lateral condyle fracture in a two-year-old child and discusses its treatment.Case: A two-years-old boy was delivered by his parents to the Emergency Room (ER) in the Wangaya Regional General Hospital Denpasar with complaints of pain in the left elbow since a day ago. Complaints appear after the patient falls on the floor in his home while playing with his brother. On physical examination of the upper extremity, the left elbow is swollen at the elbow with minimal deformity without an open wound. In manage it, open reduction surgery is performed by apply Kirschner-wire and then backslab is placed on the left arm with supination and 30o flexion positions.Conclusions: Difficulties in diagnosing humeral lateral condylus fractures in children are due to the fact that there are still many condyle plates that have not ossification yet, so that it is difficult for radiological examination to see the fracture line. The operative actions that can be taken are open reduction with the installation of Kirschner-wire. Latar Belakang: Fraktur kondilus lateral humerus pada anak dapat sulit terdiagnosis akibat tulang anak yang belum terosifikasi. Hal ini mengakibatkan gambaran fraktur sulit terlihat atau bahkan terlewati. Dalam penatalaksanaanya, fraktur kondilus lateral humerus pada anak memiliki kontroversi, antara non-operatif dan operatif (terutama pada fraktur dengan pergeseran minimal). Laporan kasus ini bertujuan untuk membahas kasus fraktur kondilus lateral humerus pada anak umur dua tahun dan membahas tatalaksananya.Kasus: Seorang anak laki-laki berumur dua tahun diantar oleh orangtuanya ke Unit Gawat Darurat (UGD) Rumah Sakit Umum Daerah Wangaya Denpasar dengan keluhan nyeri pada siku kiri sejak satu hari yang lalu. Keluhan muncul setelah pasien terjatuh di lantai rumah saat sedang bermain dengan saudaranya. Pada pemeriksaan fisik ekstremitas atas, pada siku kiri didapatkan bengkak pada siku dengan deformitas minimal tanpa disertai luka terbuka. Dalam penanganannya, dilakukan tindakan operasi reduksi terbuka dengan pemasangan Kirschner-wire kemudian dipasang backslab pada lengan kiri dengan posisi supinasi dan fleksi 30o.Simpulan: Dalam mendiagnosis fraktur kondilus lateral humerus pada anak diakibatkan masih banyak lempeng kondilus yang masih belum terosifikasi, sehingga pada pemeriksaan radiologis sulit melihat garis frakturnya. Tindakan operatif yang dapat dilakukan berupa reduksi terbuka dengan pemasangan Kirschner-wire.

Full textAbstract:
An extremely important institution among the Indians of the Southeast in the historic period, the calumet ceremony was first recognized by French adventurers in the Upper Mississippi Valley and Great Lakes region in the mid-seventeenth century. By the end of the century the ceremony was universal among Lower Mississippi Valley groups. A major focus of calumet literature in recent years has been on the timing of and the mechanism for the introduction of this ceremony in the Eastern Woodlands. Some have argued for prehistoric roots, while others have supported a historic development. A study of the spatiotemporal distribution of catlinite pipes is one way to address these issues, because such pipes are the principal archaeological expression of the ceremony. This paper focuses on the two most common catlinite pipe forms: disk pipes and elbow pipes. Overall, both forms are rare in the Southeast, but relatively they are widespread. The disk type has the greatest range and is also the earlier of the two forms, primarily being found during the protohistoric period. It is proposed here, however, that calumet introduction was coincident with the elbow catlinite form that first appeared in the Southeast in the mid-to-late seventeenth century. It is believed that calumet ceremonialism was spreading into the southern portion of the Lower Mississippi Valley at about the same time as the first French explorers were entering the area from the north.

Full textAbstract:
Extremely low birth weight infants (ELBW) are defined by birth weight of less than 1000 g and are frequently born at 27 weeks’ gestation (GW) or younger. The neonatologists’ efforts focused on improvement of intact survival rate, especially for those born at the frontiers of viability at 22/23 GW. Survival rates of >80% for the advanced gestations and > 50% for 23–24 GW have been reported. Higher gestational age and birth weight, female gender, better maternal education, and white race have been recognized as significant predictors of decreased morbidity in ELBW infants. Although the mortality rate has significantly contracted for this group with improved technology and better understanding of pathophysiology, the proportion of surviving infants without sequelae, has not improved as noticeably. We review the short and long-term morbidities in ELBW infants and compare own and literature data. We analyze some of the specific immediate problems for this group such as: respiratory problems, infection, thermoregulation, impaired glucose homeostasis and disturbed cardiovascular and excretory functions as well as late morbidities such as bronchopulmonary dysplasia, late-onset infections, central nervous system occurrences, retinopathy and anemia of prematurity. We also deal with preventive and therapeutic strategies for improved outcome in this sensitive group of patients.

This chapter examines hoplite equipment. Although elements of the bronze panoply associated with the classical hoplite began to appear in the late eighth century, what set the hoplite apart from his predecessors was above all his distinctive heavy wooden shield with a double handle, which is first attested circa 700 BC. This date may therefore be regarded as the beginning of the hoplite era. The shield has a central metal armband (the porpax), through which the bearer thrust his left forearm up to the elbow, and a hand grip (antilabe), at the rim of the shield, that he grasped with his left hand. A great deal of the debate about the origins of the classical phalanx centers on what the adoption of this type of shield might imply about the nature of hoplite fighting and battle formations.

Full textAbstract:
Abstract Combustible gas accounts for an increasing proportion of energy in countries. As the main transportation tool of combustible gas, the safety of pipeline has always been the focus of researchers. When the gas explodes, the accident consequences are greatly affected by the pipeline structure. The study on the hydrogen explosion characteristics of a typical pipe structure (elbow structure) is carried out in the paper. The results show that in pipes with large elbow angles, the flame front can form local cavity regions as flame passes through the elbows. The influence of elbow structure on flame propagation is mainly concentrated in the middle and late stages. In the middle stage, the elbow structure creates a relatively closed space in advance, so that the speed peak-2 occurs earlier than the straight pipe. In the later stage, the acceleration effect produced by the outer wall (concave wall) plays a leading role, and the flame accelerates for the third time after passing through the elbow. There is an interactive relationship between the development of the explosion overpressure and the flame propagation in the elbow.

Abstract This paper describes an environment friendly propulsion system with negligible noise. The Propulsion system is based on a novel engine called a water piston engine. All moving parts in the classical internal combustion engine are eliminated; the piston, connecting rod, and crankshaft. Also, cams and follower valves are replaced by solenoid valves which inject compressed air into the cylinders. A water column in the cylinder is used to replace the metallic piston. The water column itself inside the cylinder acts as a piston. This Water Piston Engine is powered by pressurized air only. So, a pressure vessel is used to store compressed air. The Pressure derived from the compressed air tanks is directly used in providing thrust by pushing the water out of the cylinder through a 90-degree elbow as a water jet. When the water is ejected from the cylinder and the air pressure inside the cylinder decreases to near atmospheric, the water that surrounds the engine fills the cylinder. Four cylinders are used; each two cylinders are fired simultaneously in order to maintain thrust. This system uses an Arduino microcontroller unit to deal with how much time the pressurized air is needed to discharge the cylinder and to switch the airflow between the engine cylinders. Several field tests have been made in a lake. The experimental data were compared to the theoretical based data in addition to simulate this model using Ansys fluent. The advantages of this novel engine over internal combustion engines are clarified. Videos of the experiments are recorded.

Full textAbstract:
The development of primary and secondary moment loading stress indices and analytical derivations of stress intensification factors (SIF) has matured over the past 35 years. The original development work for the ASME piping Codes SIF definitions was empirically derived well over 65 years ago and still, debates linger over the equivalence of the physical fatigue testing of piping fittings and the rapid evolution of stress classification techniques as applied specifically, to the finite element method. The trunnion elbow geometry has always presented significant mathematical challenges in the determination of stress intensification factors, which is primarily due to the complexity of the intersection created by a right circular cylinder (forming the trunnion) to a toroid (forming the elbow). This paper traces the maturation of the SIF definition for the trunnion-elbow geometry from the original roots of the Markl tests, to the early analytical formulations presented by Williams and Lewis, to the WRC and EPRI results published in the late 1990s, through today’s rendition as contained in the Appendices to the ASME B&PV Code, Section III. In addition, geometry combinations are introduced herein that have not been covered in any of the previously referenced publications. Finally, a comparison of the various formulations is tendered for consideration of the reader to determine if in fact there has been significant progress in this subject area since the early analytical work published by Williams and Lewis in the early 1980s.

Volunteer Kinematics and Reaction in Lateral Emergency Maneuver Tests. SAE International, November 2013. http://dx.doi.org/10.4271/2013-22-0013.
Full textAbstract:
It is important to understand human kinematics and muscle activation patterns in emergency maneuvers for the design of safety systems and for the further development of human models. The objective of this study was to quantify kinematic behavior and muscle activation in simulated steering tests in several realistic conditions. In total 108 tests were performed with 10 volunteers undergoing purely lateral maneuvers at 5 m/s2 deceleration or simulated lane change maneuvers at 5 m/s2 peak acceleration and peak yaw velocity of 25 °/s. Test subjects were seated on a rigid seat and restrained by a 4-point belt with retractor. Driver subjects were instructed to be relaxed or braced and to hold the steering wheel while passenger subjects were instructed to put their hands on their thighs. Subjects were instrumented with photo markers that were tracked with 3D high-speed stereo cameras and with electromyography (EMG) electrodes on 8 muscles. Corridors of head displacement, pitch and roll and displacement of T1, shoulder, elbow, hand and knee were created representing mean response and standard deviation of all subjects. In lane change tests for the passenger configuration significant differences were observed in mean peak of head left lateral displacement between the relaxed and the braced volunteers, i.e. 171 mm (σ=58, n=21) versus 121 mm (σ=46, n=17), respectively. Sitting in a relaxed position led to significantly lower muscle activity of the neck muscles. It was concluded that significantly more upper body motion and lower muscle activity was observed for relaxed subjects than for braced subjects.
