Abstract:
Methods of estimating horse body weight using mathematical formulae have better accuracy than methods of reading body weight from measuring tape. The aim of the study was to evaluate established formulae for estimating horse body weight from data gathered using measurement tape. The research was conducted in a group of 299 adult horses and ponies of selected breeds: ponies (n = 58), Polish Noble Half Breed (n = 150), Silesian Breed (n = 23), Wielkopolski Breed (n = 52), and Thoroughbred (n = 16). Body measurements were performed on each horse using a measuring stick and tape. The actual body weight of the horses was measured with electronic scale. Statistical analysis was carried out separately for individual breeds of horses. In each of the research groups formulae were selected, the results of which were closest to the actual horse body weight readings. The use of formulae for body weight estimation can be useful in determining feed dosages and additives, medicines or deworming agents. Regular weight measurement is important for maintaining a healthy horse.

Abstract:
Introduction The development of stenoses after correction of an esophageal atresia or acid and lye burn of the esophagus are well-known problems in pediatric surgery. Currently, stenoses are treated in the majority of cases by repeated balloon dilatations. The diameter of the balloons used is not standardized; standard curves do not exist. The aim of this study was to evaluate the diameter of the esophagus correlated to the body weight of the children as measured in upper gastrointestinal (GI) studies to answer the important question to what extent a stenosis should be dilated. Materials and Methods Within the time period from 2011 through 2016, 60 patients with upper GI studies were selected. Evaluations were blinded to two different examiners. The diameters were measured under maximum contrast filling between the second and third rib (cranial point of measurement) and between the seventh and eighth rib (caudal point of measurement). For both, the anteroposterior and lateral aspect was examined. The diameter was calculated as the arithmetic average of both measurements within one level. The diameters were correlated to the weight of the children. Results All children (n = 38) within the 3rd to 97th weight percentile were analyzed. Linear correlation and coefficients of 0.67 at the cranial point and 0.70 at the caudal point were found. Mean diameter at the cranial point of measurement was 6.75 mm at the lowest weight (2.6 kg) and 14 mm at 74 kg. Mean weight of these children (standard deviation [SD]) was 25.3 (18.8) kg and median age was 7 years. Within weight groups (0–10 kg; 10–20 kg; 20–35 kg; 35–50 kg; >50 kg), we calculated SD and two side tested critical 95% confidence interval for all measurements (n = 74). Conclusion Although the variation in measurements is considerable, this evaluation gives a reliable hint to which extent esophageal stenoses should be dilated in relation to the body weight. To the best of our knowledge, this is the first investigation to evaluate the diameter of the esophagus in children in relation to the body weight.

Abstract:
Background Patient body weight is a frequently used measure in biomedical studies, yet there are no standard methods for processing and cleaning weight data. Conflicting documentation on constructing body weight measurements presents challenges for research and program evaluation. Objective In this study, we aim to describe and compare methods for extracting and cleaning weight data from electronic health record databases to develop guidelines for standardized approaches that promote reproducibility. Methods We conducted a systematic review of studies published from 2008 to 2018 that used Veterans Health Administration electronic health record weight data and documented the algorithms for constructing patient weight. We applied these algorithms to a cohort of veterans with at least one primary care visit in 2016. The resulting weight measures were compared at the patient and site levels. Results We identified 496 studies and included 62 (12.5%) that used weight as an outcome. Approximately 48% (27/62) included a replicable algorithm. Algorithms varied from cutoffs of implausible weights to complex models using measures within patients over time. We found differences in the number of weight values after applying the algorithms (71,961/1,175,995, 6.12% to 1,175,177/1,175,995, 99.93% of raw data) but little difference in average weights across methods (93.3, SD 21.0 kg to 94.8, SD 21.8 kg). The percentage of patients with at least 5% weight loss over 1 year ranged from 9.37% (4933/52,642) to 13.99% (3355/23,987). Conclusions Contrasting algorithms provide similar results and, in some cases, the results are not different from using raw, unprocessed data despite algorithm complexity. Studies using point estimates of weight may benefit from a simple cleaning rule based on cutoffs of implausible values; however, research questions involving weight trajectories and other, more complex scenarios may benefit from a more nuanced algorithm that considers all available weight data.

Abstract:
The body condition score (BCS) is insufficient in determining the amount of body fat in horses, thus defining obesity. Measurement of the subcutaneous fat thickness (SFT) by ultrasonography should be considered as an appropriate method in the definition of fat distribution at different body locations in horses. Therefore, this study aimed to 1) characterize the SFT in three different anatomical locations (i.e. neck, lumbar region, and gluteal region); 2) evaluate the relationship between BCS and SFT; 3) determine the influence of gender, weight, age, and gait on BCS and SFT measurements, and 4) explore the agreement between the morphometric measurements [i.e. body mass index (BMI), girth circumference: height at withers ratio (GC: HW), neck circumference: height at withers ratio (NC: HW)], and BCS and SFT in a population of Colombian Paso Horses (CPHs). The Henneke’s body condition scoring was applied to 69 adult CPHs, selected using a convenience sampling. Additionally, BMI, GC: HW, and NC: HW were calculated. Body fat percentage (BF%) was calculated by ultrasound measurement of the SFT in the neck, lumbar region, and gluteal region. The BF% in the CPHs was 6.4 ± 1.1. The GC: HW, NC: HW, and BMI were not predictors of the BF% or BCS, and neither gender nor gait was decisive in the definition of fattening in the study animals, although age and weight were determining variables. According to our results, ultrasound is an adequate tool to calculate the BF% of the CPHs. However, it must be accompanied by Henneke’s BCS assessment.

Abstract:
Assessment of body condition of free-ranging animals is important when evaluating population health and fitness. The following study used body condition scoring, ultrasound, and dissected physical measurement to assess fat stores in free-ranging raccoons (Procyon lotor). Measurements were taken of subcutaneous fat at interscapular, thoracolumbar, and lumbosacral paraspinal and ventral midline sites. These measurements were examined in relationship to body condition scores and body weight. The ultrasound technique accurately measured the subcutaneous fat of raccoons when compared to dissected physical measurement and yielded data that strongly correlated with both body condition score and body weight, with the ventral midline measurement most strongly correlated. This noninvasive method may be useful in conjunction with body condition score and body weight when assessing the nutritional status of raccoons and potentially other small carnivore species.

Abstract:
We studied an acute and chronic oral toxicity of the extract from Ziziphus attopensis (ZA) in male and female SD rats according to the OECD guidelines. After a single oral administration of ZA 5 g/kg body weight, measurement of the body and organs, necropsy, and health monitoring were performed. The body and organ weights and behavior were not changed relative to the control rats indicating that ZA does not produce acute toxicity. The chronic toxicity was determined by oral feeding both male and female rats daily with ZA at the doses of 1, 2, 4, and 8 g/kg body weight for 180 days. Body weight changes, hematological and biochemical parameters, organ weights, gross finding, and histopathology examination were monitored during the experimental period. The results did not show any differences from the control groups. Analyses of these results with the information of signs, behavior, and health monitoring can lead to a conclusion that the long-term oral administration of ZA for 180 days does not cause chronic toxicity.

Abstract:
Background: As of 2018, 2.1 billion people nearly 30% of the world’s population are either obese or overweight. Worldwide obesity has nearly tripled since 1975. It is an emerging health problem with major adverse effects on health. It is a risk factor for many chronic diseases but is best known for its role in metabolic syndrome, which can lead to type 2 diabetes mellitus as well as cardiovascular diseases. Anti-obesity drugs are available but have many side effects. Voglibose, an antidiabetic drug, is an alpha glucosidase inhibitor which shows promising results in the reduction of body weight with minimal side effects.Methods: Voglibose (7 mg/kg) was administered to rats fed with normal laboratory chows and high fat diet to see its effect on body weight, body mass index, abdominal and thoracic circumference, and lipid profile at the end of 12 weeks.Results: Administration of voglibose significantly reduced food consumption, feed efficiency and increase in body weight induced by high fat diet in rats. Rats fed on normal diet also showed reductions in the same parameters, suggesting its weight lowering effect. Reductions in the anthropometric measurements, hypolipidemic effects and glucose lowering effects were also observed.Conclusions: Voglibose prevented high fat diet-induced obesity and improvement in metabolic profile, which ultimately has systemic effects on body weight in rats. Further studies are needed to see its potential therapeutic use in obese patients with type 2 diabetes mellitus, and related complications.

Full text
Abstract:
No research has been performed comparing percent body fat measurements using dual energy x-ray absorptiometry (DEXA) and air plethysmography after weight loss. The purpose of this investigation was to compare body composition assessments using the Bod Pod® Body Composition System (BP) and the DEXA ProdigyTM before and after an 8-week weight loss diet and exercise program. Based on prior comparison studies, it was hypothesized that percent fat values would be significantly lower using the BP compared to the DEXA before and after weight loss. Also since both methods have been shown to be reliable, it was hypothesized that the BP and DEXA would detect similar changes in percent fat in response to a weight-loss intervention. Twelve women (42 ± 8 yrs) and ten men (40 + 11 yrs) had their percent body fat estimated using the BP and whole body DEXA ProdigyTM scanner. A similar significant (P < 0.05) decrease in percent body fat was observed using the BP and DEXA ProdigyTM (-2.2% and -1.8%, respectively) after weight loss. Percent body fat using the BP was significantly lower than the DEXA ProdigyTM before (36 ± 10.7% and 38.1 ± 9.4%, respectively) and after (33.8 ± 10.8% and 36.3 + 10.6%, respectively) the weight loss program. Significant Pearson correlation coefficients between the DEXA ProdigyTM and the BP were noted pre (r = 0.975) and post (r = 0.968) weight loss. These data indicate the BP provides significantly lower absolute %fat values within a range of body fat levels (20-56%) when compared to the DEXA. However, the BP and DEXA detect similar changes in %fat, fatfree mass, and fat mass from weight loss in men and women. Also, the BP consistently overestimated fat-free mass and underestimated %fat and fat mass compared to values obtained from DEXA.

Abstract:
Introduction: There is proven therapeutic benefit in bariatric surgery for obese patients. Consequently the National Institute of Clinical Excellence UK has provided referral guidelines for bariatric surgery. Successful bariatric surgery will result in massive weight loss and ptotic skin, which can cause significant functional and psychological problems. As the number of cases of bariatric surgery increases, a corresponding number of massive weight loss patients will require plastic surgery. In this novel field of post massive weight loss surgery there is a lack of understanding of the demographics, physical symptoms and psychological health of this new group of patients. The tools to assess them are few and not validated, the patient pathway is disjointed and there is no consensus on standardised provision. Method: A prospective multicentre, observational study of outcomes in 100 patients undergoing bariatric and post massive weight loss plastic surgery at 2 clinical sites was performed. Each patient followed a standard operating protocol. This included undergoing a semi structured interview, completing five patient-report outcome measures, having anthropometric measurements and clinical photographs taken. Conclusion: This observational study identified key psychosocial themes prevalent in massive weight loss patients, during their weight loss journey. It identified there are no validated patient reported outcome measures available specific to this cohort of patients. This work led to the development of a new validated tool for massive weight loss body contouring.

Thesis (MA. Agricultural Management (Animal Production)) -- University of Limpopo, 2014
Body measurements have been used in animals to estimate body weight especially in rural areas where scales are not readily available. The study was conducted in Sekhukhune District of the Limpopo province, South Africa where the goats between the ages of 20 and 30 months were used. Body weight and four morphological traits were taken on each goat in the morning before they were released for grazing in a total of 613 indigenous goats of both sexes (62 male and 551 female). Body weight was measured in kilogram (kg) using a balance scale, hip height and shoulder height measurement (cm) were done using a graduated measuring stick and the body length and heart girth were measured in centimetre (cm) using a tape rule. Means, standard deviations (SD) and coefficients of variation (CV) of body weight and morphological traits were calculated. Pair wise correlations among body weight and morphological traits were also determined and range from 0.81-0.91 for male and 0.72-0.89 for female goats, respectively and were significant (P<0.01). The direct effect of heart girth on body weight was the strongest in both sexes (path coefficient of 0.58 and 0.62 in males and females, respectively). Body length (males) and body length and hip height (females) also positively (P<0.05) influenced body weight. The direct effects of other linear type traits on body weight in both sexes were non-significant as revealed by t-test. These traits were indirectly realized mostly via heart girth. Thus, they were removed from the final regression equations to obtain much more simplified prediction models. The optimum multiple regression equation for male goats included heart girth and body length, In female goats, however, the v variables included in the final prediction model were heart girth, body length and shoulder height. The forecast indices obtained in this study could aid in weight estimation, selection and breeding programmes.

Abstract:
This investigation sought to identify anxiety responses to weight measurement, assessed by verbal report and cardiovascular reactivity CCR3 (systolic blood pressure, diastolic blood pressure, heart rate), which might differentiate females with either high or low self-reported bulimic behavior. Secondar i ly,, the study attempted to examine specific autonomic nervous system (ANS) arousal patterns of each group over time. The Bulimia Test (BULIT), Body Dissatisfaction Scale (BD), and a demographic questionnaire were administered to 105 undergraduate females at The University of North Texas. Based on BULIT scores, females were divided into high or low bulimic behavior groups. Of the 105 females screened, forty participated in the experiment which consisted of four phases: relaxation, anticipation of weight measurement, weight measurement, and recovery. Subjects had no prior knowledge of the weight stressor until presentation during the experiment. Results showed that subjects' notion of ideal weight was substantially lower than measured weight. During weight measurement, all subjects reported increased anxiety although the high group reported significantly more anxiety. Contrary to prediction, no significant group differences in CR were found when repeated measures multivariate analysis of variance (MANOVA) was performed. Orthogonal polynomial trend analysis was done with pooled groups, resulting in significant within-subject trends for all cardiovascular measures. There was also a significant group by time of measurement interaction for heart rate during the weight measurement phase. Correlational analyses failed to produce significant results between verbal report of anxiety and CR. There was, however, a significant correlation between BULIT and BD scores. It was concluded that heightened subjective anxiety during weight measurement could not be attributed to group differences in CR. Regarding ANS arousal patterns, mixed evidence of active and passive coping was seen. Nevertheless, both psychological and physiological measures supported an overvaluation of female thinness consistent with societal trends regardless of group membership. Implications of findings were discussed along with suggestions for future research.

Abstract:
The general aim was to explore factors influencing the normal variation and measurement of body temperature. Additional aims were to study morbidity, mortality and the clinical presentation of pneumonia and predictors for survival in elderly nursing-home residents. Two hundred and thirty seven non-febrile nursing home residents (aged 66-99 years) and 87 healthy adults (aged 19-59 years) were included. In elderly individuals, the morning ear and rectal body temperature was measured at baseline and pneumonia and survival was observed at one- two and three-year. In healthy adults the rectal, ear, oral and axillary temperature were measured simultaneously on one morning and repeated measurements were performed in three subjects. Overall, the range of normal body temperature was wider then traditionally stated. In elderly nursinghome residents, functional and cognitive impairment and BMI < 20 were related to a lower body temperature and medication with analgesics to a higher. Compared to adults < 60 years elderly persons had a higher average ear and a lower rectal temperature. Men and postmenopausal women < 60 years had lower body temperature than premenopausal women. The repeated measurements showed a wide individual variability irrespective of the site of measurement, and that replicated measurements do not improve accuracy. When comparing the rectal temperature with oral, ear and axillary readings the average difference was > 0.5°C with a wide individual variation. The yearly incidence of nursing-home acquired pneumonia varied between 6.9% and 13.7%. Functional impairment, chronic obstructive pulmonary disease (COPD) and male sex were related to a higher risk of acquiring pneumonia and presenting non-specific symptoms were common. Age and functional impairment predicted mortality, irrespective of gender, while cerebral vascular insult, a lower body mass index and malnutrition in women and heart disease, COPD, medication with sedatives and mortality rate index in men were gender specific predictors. Surviving women had a higher baseline body temperature than non-surviving, while no such difference was found in men. When assessing body temperature, it is important to consider the site of measurement, technical design, operator technique, age and gender and, in elderly nursing-home residents, physical and cognitive impairment, body constitution and medication with analgesics. The best approach is to use an unadjusted mode, without adjusting to another site. To prevent a delayed diagnosis of pneumonia, one should be aware of a low baseline body temperature and lack of specific clinical symptoms in elderly nursing-home residents. Preserving and/or improving functional, cognitive, nutritional status and preventing agitation and confusion would improve survival in nursing-home residents.

Abstract:
AbstractIn view of China’s cargo airlines network, taking the airport of each city as the node and the number of flights between cities as the weight of the side, the network topology index and economic index are used to evaluate the current situation of the network and the development potential of the network. Then, the TOPSIS method is used to comprehensively evaluate China’s cargo airlines network. The results show that the network ranking of each airline is: China Cargo Airlines, SF Airlines, China Post Airlines, Jinpeng Airlines, Longhao Airlines, Yuantong Airlines. Finally, considering the development stage of China’s cargo airlines, the sensitivity analysis is conducted by resetting the weight to verify the effectiveness of TOPSIS method. At the same time, according to the different stages of the network of cargo airlines, some suggestions on the development of the network are given.

Abstract:
The purpose of this study was to determine nutritional status and its influence on their quality of life in Alzheimer's disease (AD) patients with Mini Nutritional Assessment (MNA) and anthropometric measurements. This study was conducted with 57 Alzheimer type dementia patients between the ages of 52 and 89 who live in nursing homes in Ankara/Turkey. In this study, it was found that the 57.9% of the AD patients were at risk of malnutrition, and that 19.3% were malnourished. Malnutrition risk rises as the length of stay increases (p< .05). A significant correlation between body weight and quality of life as well as one between calf circumference and quality of life was detected (p< .05). In this study, nutrient intake among aged individuals with AD was found unbalanced; a statistically significant correlation between energy / nutrient intake and quality of life also was not detected.

Abstract:
Bulk nanostructured metallic alloys as well as coatings are being research closely for biomedical applications, especially for implants. Corrosion behavior is of particular interest, given the aggressive environment of body fluids that these metals experience. While weight loss measurement and electrochemical analysis are the two commonly used techniques for corrosion behavior evaluation, both have their own limitations with respect to characterizing the corrosion of films and coatings under a micron in thickness. This paper reports on a novel application of the optical density technique as a relatively faster yet accurate method to evaluate the corrosion of thin metallic films. With this technique, the survivability and/or resorption time of a pure metallic coating is evaluated by monitoring the changes in optical density (directly related to reduction in film thickness, and thereby to weight loss) of thin film immersed in a corrosive media. In our experiments, Mg, Cu and Ag thin films of a wide range of thicknesses were sputter-deposited on glass substrates and the corrosion kinetics of these metals in a simulated body fluid was studied at room temperature. The results were utilized to develop a resorption time model for the coating, which can be used to predict the survivability of these metallic thin films.

Abstract:
Abstract Freshwater environment and high clay content are quite common in Indonesia. This introduces certain challenge in performing hydrocarbon identification and evaluation especially in already cased wells. In old producer wells, possible conditions such as fluid channeling behind casing and trapped hydrocarbon in annulus add more complexity in performing behind casing analysis to understand current reservoir condition. In order to increase the success in finding remaining hydrocarbon potential, PERTAMINA has deployed pulsed neutron logs (PNL) to accurately pinpoint the targeted interval for perforation. Since 2017, the PNL campaign has covered approximately 160 wells in PERTAMINA's development fields across Indonesia up until now. PNL service offers nuclear-based statistical measurement such as sigma, thermal neutron decay porosity (TPHI), and carbon-oxygen yield that allows simultaneous oil and gas saturation evaluation without any dependence on water salinity and other electrical properties of the formation and fluid. It also allows computation of elemental dry weight from elemental spectroscopy data which can be utilized to determine lithology to complement the standard open-hole logs dataset. The more advanced PNL tool raises the bar even further by offering new measurement of fast neutron capture cross section (FNXS) log which is useful to identify gas even in tight rock formation. The latest generation also features self-compensation algorithm resulting in more robust TPHI and sigma log under complex circumstances such as multi-casing/tubing. This paper showcases several prominent success stories of oil and gas findings identified from PNL interpretation in development wells. There are also several examples of elemental spectroscopy data utilization from PNL to prevent non-economical perforation by means of providing accurate lithology and porosity analysis as compared to previous result built from old and/or incomplete open-hole logs dataset. This PNL campaign has also given valuable insights of borehole and reservoir condition which might have been overlooked such as hydrocarbon in annulus, low pressure gas zone identification and batman's ear boundary effect. Low pressure gas zone may be qualitatively identified whenever TPHI from PNL is noticeably lower than neutron porosity measurement from the open-hole log. Batman's ear effect is usually observed when a body of sand is sandwiched between carbonaceous shales or coal layers resulting successive oil-water-oil saturation profile in one homogenous body of sand, shown as oil peaks at the bed boundaries similar with the appearance of batman's ear. As the sand gets thinner, these two oil peaks might merge into one solid body of high oil saturation which might not depict the true oil potential of the sand.

Abstract:
Developing Mg based implants for temporary applications based on their biodegradation in the physiological environment is a potential research area in the biomedical engineering. Assessing the bio-corrosion in simulated conditions helps to reduce the complexity of research studies associated with in-vivo experiments and can be used to assess the true behavior of the Mg implant in artificial solutions. On the other hand, assessing the corrosion behavior by using 3.5% NaCl solution is a standard ASTM protocol widely used in the industries. Hence, in the present work, degradation of pure Mg due to bio-corrosion in two different solutions i.e simulated body fluids (SBF) and 3.5% NaCl solution has been investigated. From the results, the weight loss measurements indicated higher degradation during the initial 24 h in SBF solution. However, with the increased immersion time to 72 h, due to the deposition of mineral phases from SBF as confirmed from the electron microscopy and X-Ray diffraction study, the degradation was observed as decreased in SBF compared with NaCl solution. Hence, the results demonstrate that the evaluation of degradation behavior of Mg based materials in simulated physiological environments is appropriate compared with the standard NaCl environment.

Abstract:
Researchers at the National Institute for Occupational Safety and Health (NIOSH) performed a pilot study focusing on the measurement accuracy of a mobile iOS application (app) to assess whole-body vibration (WBV) and seat performance on mobile mining equipment. The major objectives of this study were to assess the accuracy of an iPod app and determine if a pair of iPods running the iPod app were suitable to measure SEAT (Seat Effective Amplitude Transmissibility) value. The goal is to recommend a simple method to determine when a vehicle seat may need to be repaired, replaced, or adjusted. The study showed that the iPod app has the potential to serve as a low-cost tool to estimate WBV exposures to operators of mobile mining equipment. The study results were similar to those obtained by Burgess-Limerick et al. for operator WBV exposures on mining equipment. In contrast, an effort to examine seat performance using the mobile app showed greater variation between the app and the precision Siemens/LMS system selected as the “gold standard.” When comparing the Siemens/LMS and iPod pair systems, SEAT values calculated using weighted-root-mean-square acceleration (aw) resulted in a mean percent difference of 8.5±7.9%, whereas those calculated using vibration dose value (VDV) resulted in a mean percent difference of 5.5±4.4%. Additional data collection is necessary to determine what factors may be associated with this variance.

Abstract:
Vehicle ride comfort plays an important role in the vehicle design. Human body is very sensitive to whole body vibration. Vehicle ride comfort has brought lots of concerns in recent years due to requirement of better ride comfort performance for newly developed vehicles. Vehicle ride comfort has a direct effect on driver’s performance and will result in overall customer satisfaction. Various papers have reported vehicle ride comfort and various biodynamic models have been built in the literature. However, there is a lack of a comprehensive literature survey to summarize all biodynamic models for whole body vibration and vehicle ride comfort. The purpose of this paper is to have a literature review of biodynamic models. So this paper initially focuses on various health issues due to whole body vibrations. Whole body vibration transfers environmental vibration to human body through a large contact area. Vibration evaluation methods such as weighted root mean square (r.m.s.) acceleration method, fourth power VDV method are discussed. Along with that the paper will focus on various biodynamic response functions. Human models in the literature are divided into three main groups: lumped parameter (LP), finite element model (FE), and multibody model (MB). In the LP model, human body is represented by several concentrated masses which are connected by springs and dampers. The FE model considers that human body consists of numerous finite elements. And in MB model, human body is made of several rigid bodies connected by bushing element for both translational and rotational motion. So this paper thoroughly summarizes various models developed to reduce human body vibration. At the end, four different approaches of assessing ride comfort are summarized. These four approaches are ride measurement in vehicles, ride simulator test, shaker table test and subjective ride measurement.

Abstract:
Abstract Tremor, or an involuntary and oscillatory movement of a body part, is a cardinal symptom of Parkinson’s disease (PD) that can significantly impact activities of daily living in people with PD (PwPD). Although tremor can be mitigated with anti-PD medications, medication effectiveness is mixed for PwPD. Therefore, daily monitoring and assessment of tremor are of interest to PwPD, clinicians, and researchers. While several sensors and wearable devices have been developed and introduced to the consumer market, high costs limit their accessibility. The current research is two-fold. First, an assessment system based on multiple algorithms is developed for evaluating the reliability of measurements of PD symptoms: hand tremor and finger/hand movement speed. Second, an Android mobile application was designed and developed to capture finger-tapping frequencies and measurements of several PD symptoms like hand tremor. A healthy young adult participant produced a self-generated tremor for this study. The participant held the portable device and conducted self-measurements by following in-app instructions. Resting tremor was measured while the participant rested his upper extremity on the arm of a chair, postural tremor was measured while he maintained a position against gravity, and kinetic tremor was measured during a movement task. Data collection took approximately fifteen minutes. The linear and rotational motions, respectively, were collected by accelerometers and gyroscopes embedded within the mobile device. The results were captured and delivered to a cloud database. An assessment system with multiple algorithms provided a final evaluation of the participant’s tremor. The process included three parts. First, calculation of root-mean-square (RMS) values at all linear and rotational directions was conducted to provide tremor strength. Second, fast Fourier transform (FFT) extracted the peak frequency at each direction. The powers of peaks were compared and the highest peak was defined as the dominant frequency and that frequency’s corresponding direction of motion. Third, hand and motion correlation analysis was used to find any coherence of tremor on 3-D motions. To test the reliability of motion measurement, the same motion input was applied to multiple devices simultaneously. The outputs of different types of mobile devices were evaluated, while considering various factors and models of mobile devices in the market (i.e., device size, weight, operating system, sampling frequency, and accuracy during the measurement). Multiple trials were conducted to test the reliability of the assessment system and the performance of the mobile app. Additionally, the mobile application supports finger tapping tests that measure hand movement speed, which is commonly impaired in PwPD. Both tremor and movement speed measurements can be used to evaluate disease progression over time and could support focused medication adjustments based on symptom data.

Abstract:
This paper presents the result of an evaluation program for the condition of the SEPTA Broad Street subway car shells and their capability to perform during an extended period of revenue service. SEPTA currently is evaluating various system upgrades to address equipment obsolescence and reliability, and wanted to verify that the current car shells are expected to be serviceable during this extended period. The evaluation focused on two aspects of the 1982-built car shells. First, what is the current and predicted condition of the shells and, second, how does the performance of the current car shell design compare to present day designs and requirements? Four sets of activities were done as part of this project. One-third of the fleet was randomly chosen for visual inspections. Service-induced cracks were identified at two locations: in ring welds below the doors, and on the side sill between the corner posts and the anti-climbers. The ring weld cracks have been identified on a small number of cars in the past, and SEPTA continues to monitor and reinforce these areas. The cracks between the corner posts and anticlimbers are also being monitored; to date, none of these cracks has progressed to the point that repair is required. In parallel with the visual inspections, the car shell camber and doorway dimensions were measured on approximately 10% of the fleet. All the measured vehicles had positive camber; doorway dimensions were uniform, except for scattered individual measurements that were car-specific. This part of the evaluation concluded that the car shells are not undergoing significant degradation or cracking. One car was instrumented with strain gauges in potential high-stress areas, and then operated at simulated full passenger-load weight over the Broad Street route. Cyclic strains imposed by simulated revenue service were measured and converted to stresses. This testing confirmed high stresses at the joint between the side sill and the body bolster. The lifetime limiting location on the car shells is in the ring welds below the doors, consistent with the results of the visual inspections. Using conservative assumptions of continuous full passenger loading and minimum material properties, the predicted lifetime to the initiation of visible cracks in this area is 7–14 years of service. This independent evaluation is consistent with the actual experience, and provided confidence in the analysis protocol. SEPTA is monitoring this location and repairing cracks as required. Evaluation of the car shell design with regard to performance in a collision revealed that, unlike most other cars of its era, the Broad Street car shell contains provisions to manage energy absorption during a low-speed collision. Records obtained from a car repair shop showed that, when a Broad Street car had a significant non-revenue end collision, these provisions worked as intended to localize the deformation. In similar collisions, the Broad Street car shell will not perform significantly different from cars built to current industry practices. Results from this study indicate that with continued attention to car shell condition, including regular inspections and limited repairs, the Broad Street car shells will continue to be safe and serviceable for an extended period.

Full text
Abstract:
Abstract The uncertainties associated with wellbore placement especially in terms of subsurface geology must be understood and minimized to maximize reserves for high returns. In the study area, the target reservoir is characterized as deep-seated hot sand body with intercalations of shale and siltstone. It is directly overlain by a thin bed of calcite. A closer look at the gamma ray log response of the sand puts a question to the reservoir presence, thus making landing point uncertain. Drilling to the target reservoir requires traversing through several depleted reservoirs sandwiched by shale formations that retain their original pressures. This narrows the safe mud weight window that could lead to wellbore instability issues. Other uncertainties include depth and fluid contacts. The objective of the well was to land and geosteer the wellbore in an optimal position within the oil leg. This paper reveals how the above-mentioned uncertainties were managed while drilling GX-04h infill well. The methodologies adopted include the use of reliable rotary steerable system, improved formation evaluation tools, real-time shale volume (Vshale) modeling, real-time pore pressure/ fracture gradient/ shear collapse pressure monitoring, real-time geological modeling, mud logging and effective communication protocols. Real-time Vshale computed and mudlog data helped in differentiating the top of deep-seat hot sand from the overlying shale. The at-bit resistivity measurement and neutron/density data aided in fluid typing/contacts. The approaches employed helped in proper landing of the well and successful drilling/ geosteering of 1000 feet lateral hole section within the oil leg of the target reservoir.

Abstract:
Background. Automated-entry consumer devices that collect and transmit patient-generated health data (PGHD) are being evaluated as potential tools to aid in the management of chronic diseases. The need exists to evaluate the evidence regarding consumer PGHD technologies, particularly for devices that have not gone through Food and Drug Administration evaluation. Purpose. To summarize the research related to automated-entry consumer health technologies that provide PGHD for the prevention or management of 11 chronic diseases. Methods. The project scope was determined through discussions with Key Informants. We searched MEDLINE and EMBASE (via EMBASE.com), In-Process MEDLINE and PubMed unique content (via PubMed.gov), and the Cochrane Database of Systematic Reviews for systematic reviews or controlled trials. We also searched ClinicalTrials.gov for ongoing studies. We assessed risk of bias and extracted data on health outcomes, surrogate outcomes, usability, sustainability, cost-effectiveness outcomes (quantifying the tradeoffs between health effects and cost), process outcomes, and other characteristics related to PGHD technologies. For isolated effects on health outcomes, we classified the results in one of four categories: (1) likely no effect, (2) unclear, (3) possible positive effect, or (4) likely positive effect. When we categorized the data as “unclear” based solely on health outcomes, we then examined and classified surrogate outcomes for that particular clinical condition. Findings. We identified 114 unique studies that met inclusion criteria. The largest number of studies addressed patients with hypertension (51 studies) and obesity (43 studies). Eighty-four trials used a single PGHD device, 23 used 2 PGHD devices, and the other 7 used 3 or more PGHD devices. Pedometers, blood pressure (BP) monitors, and scales were commonly used in the same studies. Overall, we found a “possible positive effect” of PGHD interventions on health outcomes for coronary artery disease, heart failure, and asthma. For obesity, we rated the health outcomes as unclear, and the surrogate outcomes (body mass index/weight) as likely no effect. For hypertension, we rated the health outcomes as unclear, and the surrogate outcomes (systolic BP/diastolic BP) as possible positive effect. For cardiac arrhythmias or conduction abnormalities we rated the health outcomes as unclear and the surrogate outcome (time to arrhythmia detection) as likely positive effect. The findings were “unclear” regarding PGHD interventions for diabetes prevention, sleep apnea, stroke, Parkinson’s disease, and chronic obstructive pulmonary disease. Most studies did not report harms related to PGHD interventions; the relatively few harms reported were minor and transient, with event rates usually comparable to harms in the control groups. Few studies reported cost-effectiveness analyses, and only for PGHD interventions for hypertension, coronary artery disease, and chronic obstructive pulmonary disease; the findings were variable across different chronic conditions and devices. Patient adherence to PGHD interventions was highly variable across studies, but patient acceptance/satisfaction and usability was generally fair to good. However, device engineers independently evaluated consumer wearable and handheld BP monitors and considered the user experience to be poor, while their assessment of smartphone-based electrocardiogram monitors found the user experience to be good. Student volunteers involved in device usability testing of the Weight Watchers Online app found it well-designed and relatively easy to use. Implications. Multiple randomized controlled trials (RCTs) have evaluated some PGHD technologies (e.g., pedometers, scales, BP monitors), particularly for obesity and hypertension, but health outcomes were generally underreported. We found evidence suggesting a possible positive effect of PGHD interventions on health outcomes for four chronic conditions. Lack of reporting of health outcomes and insufficient statistical power to assess these outcomes were the main reasons for “unclear” ratings. The majority of studies on PGHD technologies still focus on non-health-related outcomes. Future RCTs should focus on measurement of health outcomes. Furthermore, future RCTs should be designed to isolate the effect of the PGHD intervention from other components in a multicomponent intervention.

Abstract:
The body condition (BC) score is recognized in the dairy industry as an essential tool for managing the energy reserves of the dairy cow, which is essential for sustaining optimal and efficient production over several lactations. The current use of BC scoring depends on the accuracy of subjective visual estimates, and this limits its kusefulness as a management aid in the dairy industry. A measuring tool that would frequently provide objective data on the cow's body reserves would be a major contribution to efficient dairy herd management. Ultrasonic sensors have the potential to be developed into an efficient BC measuring device, and the experimental use of such sensors for subcutaneous fat thickness (SDFT) estimates, as an indication for BC in beef cattle, supports this assumption. The purposes of this project were: 1. To compare visual BC scoring and ultrasonic fat thickness with on-line automated body weight (BW) measurements as monitors of nutritional adequacy of dairy cows at various stages of lactation. 2. To determine the effects of variation in digestive fill in early and late lactation on the accuracy of body weight measurements in lactating cows. 3. To modify an existing ultrasonic system and develop a specialized, low-cost sensor for repeatable determination of body condition scores by users with minimal training and skill. 4. To develop a standard for the assignment of body condition scores based on ultrasonic measurements of subdermal fat thickness. The procedure to execute these objectives involved: 1. Frequent measurement of BW, milk yield (MY), BC (visually scored) and subdermal fat thickness ultrasonically measured of dairy cows, and data analysis on average and individual basis. 2. Testing and selection of an appropriate special-purpose sensor, finding an optimum body location for working an ultrasonic measurement, prcessing the signals obtained, and correlating the resulting measurements with performance responses in lactating cows. Linking the ultrasonic signals to BC scores, and developing a BC scoring data acquisition system are the first steps towards fulfilling the necessary requirements for incorporating this device into an existing dairy herd management system, in order to provide the industry with a powerful managment tool. From the results obtained we could conclude that: 1. BC does not correlate with BW changes during all stages of lactation, although in general terms it does. These results were confirmed by individual cow BW and BC data obtained during the course of lactation, that were supported by individual objective ultrasonic measurement of SDFT. 2. BW changes reflect energy metabolism reliably ony after peak milk yield; early in lactation, a decrease in BW expresses mobilization of body reserves only qualitatively, and not quantitatively. 3. Gastrointestinal content increases throughout the whole period during which dry matter intake (DMI) increases. The drastic increase very early in lactation prevents the use of BW changes as a basis for quantitative estimatio of energy meatabolism; at this stage of lactation, konly a BC score or any other direct measurements willl provide a quantitative estimate of energy metabolism. 4. Ultrasonic measurements of subdermal fat thickness can be used to quantify changes that correlate with the actual condition of the cow, as assessed by performance and the traditional way of scoring. 5. To find the best site on the cow's body at which to obtain responses to BC and its changes in the course of lactation, additional sites have to be examined. From the present study, it seems that the sites between ribs 12 and 13 have the potential for this purpose. 6. The use of templates made it easier to repeat measurements at a desired site and spot. However, the convenient easy-to-handle way to standardize the measurement, described in this study, koffers scope for improvement. 7. The RF peak values of the A-mode are better indicators of the location of fat layer borders than image analysis, from the point of view of future commercial development. 8. The distances between the RF peaks of the A-mode can be automatically measured by suitable software, for future commercial development. 9. Proper analysis of daily body weight and milk yield data can provide the necessary information on body condition changes during lactation, until a direct BC measurement device is developed. 10. In any case, at least one visual BC assessment has to be done, preferably immediately after calving, for calibration purposes.

Abstract:
Community Development Financial Institutions (CDFIs) are grassroots organizations that provide equitable access to financial capital. While a robust body of evidence supports the ability of CDFIs to promote holistic and sustainable development, attempts to systematically evaluate the industry have yielded disparate and often confounding results. We apply an institutional theory lens to examine challenges to meaningful data collection, impact measurement, and program evaluation. Our data show how regulators, major funders, and third-party rating organizations have applied indirect and direct pressures that have systematically lowered the capacity of nonprofit CDFI loan funds. This combination of coercive, mimetic, and normative isomorphic forces has (1) hampered meaningful data collection, (2) created a lack of staff expertise in these areas, (3) raised the cost and complexity of utilizing technology systems to improve evaluation processes, and (4) fostered industry norms which de-prioritize meaningful evaluation. The data suggest several ways for stakeholders to improve these trends. For example, funders might consider providing support which builds organizational capacity via unrestricted operating grants and recurring financial commitments.
