Driving to Comply: Mind Genomics, Arizona, and the COVID-19 Vaccine

The study reported here represents the first effort to apply the emerging science of Mind Genomics to the citizens of an entire state, with the goal of improving about the during the rather than as an academic exercise AFTER the virus. The paper presents a statewide study of responses to COVID-19, done in Arizona, USA, as preparation for the upcoming vaccine, promised for 2021. The objective is to determine the key messages which would engage Arizonans, and interest them in as preparation for a state-wide vaccination campaign. The process followed the Mind Genomics protocol, a protocol used to uncover how people think about the ordinary topics of their lives, done by exposing them to systematic combinations of messages, and determining which individual messages drove their ratings. The data confirmed previous North American findings, that there are two major mind-sets when it comes to COVID-19, the Pandemic Onlookers who are not involved and are engaged by one set of messages, and the Pandemic Citizens, who are involved, want to be guided by the government, and are engaged by another set of messages. These two mind-sets distribute throughout the population but can be quickly identified through a six-question, 30-second intervention, the PVI, Personal Viewpoint Identifier.

Evaluation of knee joint stresses during kneeling work

Kneeling is a daily activity for some occupations like carpet layers, miners, tile layers, floor layers, electricians, shipbuilders and many others. Several studies have shown that there is an association between kneeling or squatting and development of osteoarthritis of the knee joint. Even though this relationship has been established, few research studies have been conducted to estimate actual knee stresses and the role of kneepads in reducing these stresses while kneeling. Hence, this study looks at estimating the stress on the knees during simulated kneeling work while wearing six different types of kneepads. Custom force sensors were fabricated using FlexiForceTM Sensors and were placed on both knees over anatomically defined landmarks on the patella and tibial tubercle. Ten participants were recruited and consented to perform a series of kneeling tasks. Five wooden platforms were placed in five different locations surrounding two force plates and custom made three-axis load cells where the participants knelt. A set of five lettered, ceramic tiles were given to each participant and randomly placed on each platform with a corresponding letter. Estimated kneeling reaction forces derived from sensor values were used to quantify the effectiveness of each design in reducing the applied forces on the knee joint. Also these forces were used to verify the significance of location on force. The data from both the sensors and the force plates and load cells were analyzed for results. Two-way analysis of variance (ANOVA) with repeated measures, where kneepad and location were the independent variables and calculated applied force
Design and Characterization of a Radio Frequency MEMS Inductor Using Silicon MEMS Foundry Process

A successful design of RF inductor based on a silicon MEMS foundry process is presented. The suspended inductor has been realized in electroplated thick nickel with front side bulk micromachining of the substrate. The overall size of the inductor is about 1 mm x 1 mm. The inductors have been experimentally characterized and inductances around 2 nH in the frequency range of 200 MHz-7 GHz have been measured with self resonant frequency of 9.8 GHz. The peak measured value of the Q factor is 12 at a frequency of 4 GHz. After de-embedding, the Q factor reaches 13 at a frequency of 4.8 GHz. Simulation based on a parameter extraction method has been carried out for the inductor. There is a good agreement between simulated and experimental results.
Automating Supplier Selection Procedures

This dissertation describes a methodology, tools, and implementation techniques of automating supplier selection procedures of a small and medium-sized agile virtual enterprise. Firstly, a modeling approach is devised that can be used to model the supplier selection procedures of an enterprise. This modeling approach divides the supplier selection procedures broadly into three stages, the pre-selection, selection, and post-selection stages. Secondly, a methodology is presented for automating the supplier selection procedures. The methodology first divides the selection process into three stages, such as pre-selection, selection, and post-selection stages. Then the methodology identifies the steps within the selection stage that can automated. Automating the steps within the pre-selection and the post-selection stages are not considered here. The methodology also proposes three modules for automating the selection stage. To assist automation, the selection stage is further divided into three sub-stages, namely, bidder selection, partner selection and performance evaluation sub-stages. By this methodology, each sub-stage of the selection stage employs a module for automation; the modules used for automation at these sub-stages are the data collection system, the inference engine and the performance evaluation engine. Thirdly, modeling, design and implementation of the three modules for automation are described.
Convection and flow boiling in microgaps and porous foam coolers

Title of Document: CONVECTION AND FLOW BOILING IN MICROGAPS AND POROUS FOAM COOLERS Dae Whan Kim, Doctor of Philosophy, 2007 Directed By: Professor Avram Bar-Cohen Professor Bongtae Han Department of Mechanical Engineering An open and foam-filled microgap cooler, providing direct liquid cooling for a simulated electronic/photonic component and which eliminates the problematic thermal resistance of the commonly-used thermal interface material (TIM), is examined. The single phase heat transfer and pressure drop results of water are used to validate a detailed numerical model and, together with the convective FC-72 data, establish a baseline for microgap cooler performance. The two-phase heat transfer characteristics of FC-72 are examined at various microgap dimensions, heat fluxes, and mass fluxes and the results are projected onto a flow regime map. Infrared (IR) thermography is used to explore the two-phase characteristic of FC-72 inside the channel instantaneously. Also the single and two-phase heat transfer and pressure drop of porous metal foam which can enhance the cooling capability of low conductive fluid are studied and compared with the performance of the open channel microgap cooler in terms of volumetric heat transfer rate and required pumping power. The single-phase experimental results were in good agreement (within 10% error) with classical correlation of single-phase heat transfer coefficient and pressure drop in micro single gap channel with heat transfer coefficients as high as 23 kW/mK at 260 μm gap with water and 5 kW/m-K at 110 μm gap with FC-72. Annular flow was found to dominate the two-phase behavior in the open channel yielding FC72 heat transfer coefficients as high as 10 kW/m-K at 110 μm gap channel. The single-phase pressure drop and heat transfer coefficient experimental results are compared with existing correlations and achieved 10 kW/m-K of heat transfer coefficient at 95% porosity and 20PPI with water and 2.85 kW/m-K with FC-72 at the same configuration. For the two-phase flow boiling, it is found that large pore size provides better cooling capability. CONVECTION AND FLOW BOILING IN MICROGAPS AND POROUS FOAM COOLERS
Security Architecture for the Internet Protocol in 2006

Internet Protocol has become the standard communication channel when deploying wide area computer networks. Dating back to the early 1980s, IPv4 design does not provide the necessary features to establish secure channels between peers and networks. Such a feature is required by many modern applications. It is common that security policies of networked communities mandate communication over untrusted links to be carried out in a secure way at the lowest possible layer of the network protocol stack. Security Architecture for the Internet Protocol was designed to overcome the limitations of the Internet Protocol and solve these problems. It has become apparent that the components of the initial version of the security architecture released in the mid 1990s are not optimally designed and flawless in terms of security. In December 2005 updated revisions of the relevant specifications were released. This paper examines the most significant changes introduced by the current revision of the Security Architecture for the Internet Protocol.
TURBO-ROUNDABOUT GENERAL DESIGN CRITERIA AND FUNCTIONAL PRINCIPLES: CASE STUDIES FROM REAL WORLD

Compared with usual roundabouts the main advantages of turbo-roundabouts are the reduction in the number of potential conflicting points and the lower speed of passing vehicles through the intersection; they both can improve road safety conditions at the junction. Also, the physical delimitation among lanes limits the side-by-side accident risk. These aspects make turbo-roundabouts more appropriate than roundabouts when a higher level of safety has to be guaranteed, particularly in presence of relevant pedestrian and two-wheels traffic volumes. In a previous paper authors proposed a theoretical approach to evaluate turbo-roundabouts capacity founded on gap acceptance theory. In particular, to model in a realistic way traffic conditions at turbo-roundabouts, simulations have been developed starting from behavioral parameters (critical gap and follow-up time) obtained by field observations on the few existing turbo roundabouts. The determination of the advantage domain (in terms of capacity) of turbo-roundabouts compared with typical ones and the way to value performance indicators (delays, queue lengths and levels of service) more consistent with real operational conditions of turbo roundabouts were also proposed. The present paper has three main objectives: 1. to discuss general design criteria and functional principles of turbo roundabouts; 2. to give the geometric design principles of the central island and circulating lanes; 3. to present three case studies from real world concerning the conversion of existing roundabouts into turbo roundabouts. Although results of the study cannot be generalized, by methodological point of view they can be useful to the practitioners and to the road administrations in decision making about the conversion of existing intersections.
Do Lab Parameter Could be used as Indicators of Severity in Case of Acute Cholinestrase Inhibitor Insecticides?

Background: Cholinestrase inhibitor insecticides considered one of the most common causes of morbidity and mortality due to poisoning especially in developing countries like Egypt. This work aims to study the possible role of Creatine Phosphokinase (CPK), Amylase, Lactate Dehydrogenase (LDH), C-Reactive Protein (CRP) and blood sugar status in predicting the severity of acute cholinesterase inhibitor insecticides poisoning at the time of admission. Subjects and Methods: This work was done at Poison Control Center of Ain Shams University Hospitals – Egypt, and was carried on 150 patients admitted with acute (CEI) insecticides poisoning. Clinical evaluation of the patients and poisoning severity was graded according to Peradynia organophosphorus poisoning (POP) scale, then venous blood sample was collected from patients and examined for CPK, Amylase, LDH, CRP and random blood sugar (RBS). There is significant increase of CPK, LDH, CRP RBS and amylase enzyme specially with increase the severity in those patients admitted to ICU rather than inpatient, and in mechanically ventilated patients rather than non mechanically ventilated and in died patients rather than survivors. Conclusion: CPK, Amylase, LDH, CRP and random blood sugar could be used to predict severity of cholinesterase inhibitor insecticides poisoning. They can also predict ICU admission, mechanical ventilation need and mortality. Amylase is a better predictor of respiratory failure and need of mechanical ventilation.

Development and Validation of the Wheelchair Seating Discomfort Assessment Tool (WcS-DAT).

Wheelchair seating discomfort is an important but poorly understood negative outcome for long duration wheelchair users. A major impediment to the study of this problem is the lack of a validated tool for quantification of wheelchair seating discomfort. The goal of this dissertation research was to develop and validate an assessment tool appropriate for the quantification of wheelchair seating discomfort among long duration (more than 8 hours per day) wheelchair users. This was accomplished through the completion of three research phases, each described within the body of this dissertation. Phase I consisted of a qualitative research study involving in-depth interviews with experienced wheelchair users. Data from these interviews resulted in the development of the Wheelchair Seating Discomfort Assessment Tool (WcS-DAT), a three-part tool to allow wheelchair users to quantify their level of seating discomfort. Phase II of the research assessed the reliability and concurrent validity of this assessment tool through a test/re-test reliability study. Intra class correlation (ICC) coefficient scores ranged from 0.83 to 0.97, indicating adequate reliability of the two discomfort scores in the WcS-DAT. Internal item consistency, assessed using Cronbach's alpha, indicated that all items were consistent and not redundant, with scores ranging from 0.82 to 0.92. Pearson product-moment correlations were used to assess the concurrent validity of the WcS-DAT and all of these correlations were significant at a minimum of p less than 0.05, with many significant results at the 0.01 and 0.001 levels. These results indicated good concurrent validity of the WcS-DAT. In Phase III, the WcS-DAT was evaluated for its ability to show changes in discomfort over time and with the introduction of novel, user adjustable wheelchair seating. Both the General Discomfort Assessment score (GDA) and the Discomfort Intensity Score (DIS) were sensitive to changes in seating discomfort level and were adequate for use in detecting differences associated with changes in duration of sitting as well as those associated with use of different seating equipment. Results of this final phase indicated that the WcS-DAT is a useful tool for evaluation of wheelchair seating discomfort in a research or clinical environment.
Equivalent units of production: a new look at an old issue

Purpose – This paper focuses on the determination of the cost completion rate used to calculate the equivalent units of production in a continuous process costing system. The paper aims at two research questions. What procedures do companies utilize in practical terms? How should the completion level percentage be calculated conceptually? Design/methodology/approach – The study is a qualitative exploratory survey. The companies targeted were those noted in “Melhores e Maiores,” a ranking of the best and biggest Brazilian companies. A total of 175 questionnaires were sent to pre‐selected enterprises, each with revenues of more than US$100 million per year, and 50 usable responses were returned.Findings – A literature review of the theoretical procedures used for continuous process costing revealed no indication of an objective method for determining the completion level. The empirical research in the present study confirmed that, in practice, companies do not adopt the general procedures proposed by the the.

HEALTHY RICE CANOPY FOR OPTIMAL PRODUCTION AND PROFITABILITY

Poor rice crop management, especially nutrient application and seeding rate contributes to pest problems and yield fluctuations. In many cases, rice growers did not get benefit because of high inputs for nitrogen fertilizer and fungicides. Therefore, it is essential to aim for growing rice crops with reduced nitrogen application and pesticide use besides maintaining the yield sustainability. The close relationship between certain physiological straits as well climate inside the rice canopy and disease development in response to nitrogen and seedling density suggested "the healthy rice canopy" concept as a viable and productive approach. The main objective is to link the crop and nutrient management tidily together for producing rice crops with better growth, grain yield and disease resistance. To have access to this, various physiological straits of rice crops such as tillering ability, leaf area index, leaf angle etc that might contribute to the changes in microclimate inside the canopy and disease development were reviewed. The recent study on the healthy rice canopy in the Cuulong Delta Rice Research Institute was also briefly discussed.

Treatment of palm oil mill effluent using microorganisms

Palm oil mill effluent (POME) is produced in large volumes by many of the palm oil mills in Malaysia and poses a major source of pollution. POME contains large quantities of organic matter in the form of total solids that contribute to high biological oxygen demand (BOD) and chemical oxygen demand (COD) in wastewater if left untreated. A study was conducted to evaluate the potential use of Trichoderma harzianum and the mix culture of Trichoderma harzianum and Penicillium for the treatment of POME in reducing the pollutant. Using central composite design (CCD) experiment, each flask containmg 100 ml POME is treated with an inoculums consisting of 3% inoculums containing 3 x 108 spores/ml and fermented in shake flask with pH 3,6,9 and the agitation speed; 50, 150,250 rpm and incubated at 30°C for 5 days. Sample of the POME were analyzed at 24 intervals for BOD, COD and total suspended solids (TS). The result showed that the mix culture of Trichoderma harzianum and Penicillium gave better reduction of COD, and TSS with a value of 87.5% and 28.9%, respectively as compared to Trichoderma harzianum in which the value for reduction of COD and TSS is 85.2% and 27.2%, respectively at day 5 of the treatment.
Why software projects fail? Empirical evidence and relevant metrics

In this paper we present an empirical study on factors that cause the success or failure of a software project. The study deals with the definition and validation of metrics and indicators to make more objective the meaning of success (and conversely failure) of a project, and correlates characteristics of a project (such as experience of the staff and the project manager, techniques used for requirement engineering, and so on) with its result. The study, performed on a number of Italian companies, can be easily replicated in other countries or within a company, in order to assess its software processes and steer its process improvement initiatives.
