Advertisements for dictionaries usually comment on the amount of information given, but few if any give any notion to the layout of the product. What fonts are used, what is the paper quality, and binding? We assume that the layout of a dictionary is quite important for the dictionary user, and we are therefore convinced that the lexicographer (who has to know about the needs of the dictionary user) should be more in control of the layout of his dictionary. With today's desktop publishing tools at hand the gap between printer and editor has lost some of its width and this calls for increased cooperation between the two. In this article we will try to prove this by examining and criticising a number of existing dictionaries and by giving some clues as to how layout can be like. The latter is exemplified by extracts from a few new dictionaries.

The desire for functional replacement of a missing hand is an ancient one. Historically, humans have replaced a missing limb with a prosthesis for cosmetic, vocational, or personal autonomy reasons. The hand is a powerful tool, and its loss causes severe physical and often mental debilitation. Technological advancements have allowed the development of increasingly effective artificial hands, which can improve the quality of life of people who suffered a hand amputation. Here, we review the state of the art of robotic prosthetic hands (RPHs), with particular attention to the potential and current limits of their main building blocks: the hand itself, approaches to decoding voluntary commands and controlling the hand, and systems and methods for providing sensory feedback to the user. We also briefly describe existing approaches to characterizing the performance of subjects using RPHs for grasping tasks and provide perspectives on the future of different components and the overall field of RPH development.

Background:Handgrip muscle strength test describes the strength of the hand muscles used to grasp or grip. Currently, hand grip evaluation is often used in clinical practice, as a marker of function and disability. In fact, it has already been applied as an outcome measure in arthritis rheumatoid clinical trials, to demonstrate the benefits of several treatments [1]. However, hand disability should also be considered in all other rheumatological diseases.Objectives:The main aim of this study is to assess the handgrip muscle strength test in a rheumatological cohort of patients as compared to a control group.Methods:This is a cross-sectional pilot study. We considered eligible 35 rheumatological consecutive female patients followed at our outpatients’ clinic of Internal Medicine (I Policlinico of Naples) and 35 healthy control females (HC). Both groups included only right-handed individuals. Rheumatological patients were distributed as follows: 5 rheumatoid arthritis (14,3%), 9 psoriatic arthritis (25,7%), 4 systemic lupus erythematosus (11,4%), 10 systemic sclerosis (28,6%), 4 fibromyalgia (11,4%), 3 juvenile idiopathic arthritis (8,6%). The course of disease was under optimal treatment in all patients.The type of hand grip used is the power grip, in which an object is held firmly by wrapping the fingers around it, pressing the object against the palm, and using the thumb to apply counter-pressure. We considered as either right or left hand valid measure the mean of three consecutive tests per arm. Between-groups differences were tested both by a uni- and multivariable analysis.Results:The two subgroups were homogeneously distributed for age (median age 42 yrs. [IQR 33-48] vs. 36 yrs. [IQR 30-52] in HC; p=0.902). At univariate analysis, hand grip strength was significantly lower in the rheumatological patients, both at right hand (right 19.5 kg [IQR 13.6-24.8] vs. 24.5 kg [IQR 20.8-29] in HC; p=0.004) and left hand (18.5 kg [IQR 13.9-22.5] vs. 23.7 kg [IQR 19-27.3] in HC; p=0.002), as compared to HC. This finding was further confirmed at multivariable analysis only as for the left hand (OR 0.919, 95%CI: 0.858-0.984; p=0.016).Conclusion:Rheumatological diseases are burdened by hand disability, mostly affecting daily activities performance [2,3]. Beyond an optimal disease control, our pilot study shows a decrease in left hand strength as compared to healthy controls. This might be due to a reduced use of the non-dominant hand, which may lead over time to a higher deficit of strength. As such, these patients should be prescribed to a left hand exercise to improve both mobility and strength and, consequently, hand function.References:[1]Eberhardt K, Sandqvist G, Geborek P (2008) Hand function tests are important and sensitive tools for assessment of treatment response in patients with rheumatoid arthritis.

The ongoing COVID-19 pandemic began quite unexpectedly for all countries of the world community, although WHO has repeatedly warned about its possibility. It turned out that spreading of infection in all countries of the world depends not only on the level of urbanization and population density per 1 km2, but on the capability to effectively mobilize the national health system and on the quality of medical services, on their accessibility to all sectors of society, on the ability of the states leaders to provide appropriate regulation of public life. The most effective tools in the world became self-isolation, remote work (distance working) and introduction of quarantine regimes. Continuance of such measures implies, on the one hand, developing technologies for monitoring and ensuring social contact between citizens, and on the other, tightening control over the citizens behavior, including in remote work mode. The article provides a comparative analysis of these control systems, including the “social credit” in China, and concludes that remote working and opportunities that modern tracking and person re-identification technologies provide can be used even after the 2020 pandemic.

Used in close proximity to dental practitioners, dental tools and devices, such as hand pieces, have been a possible risk factor to hearing loss due to the noises they produce. Recently, additional technologies such as CAD/CAM (Computer Aided Design/Computer Aided Manufacturing) milling machines have been used in the dental environment and have emerged as a new contributing noise source. This has created an issue in fostering a pleasant hospital environment. Currently, because of issues with installing and manufacturing noise-reducing products, the technology is impractical and insufficient relative to its costly nature. In this experiment, in order to create a safe working environment, we hoped to analyze the noise produced and determine a practical method to attenuate the noises coming from CAD/CAM dental milling machines. In this research, the cause for a noise and the noise characteristics were analyzed by observing and measuring the sound from a milling machine and the possibility of reducing noise in an experimental setting was examined using a noise recorded from a real milling machine. Since a milling machine generates noise mainly due to vibration of the dust collector, the possibility of reducing noise was examined by controlling vibration. This study was conducted to understand the cause for noise from the milling machine and verify the possibility of improving noise by a tactile transducer.

Abstract Background Adherence to daily inhaled corticosteroid medication is important for asthma control but low health literacy is a barrier to comprehension of control status and may contribute to medication nonadherence. Infographics tailored with patients' own data can support comprehension of health status, but these have not been applied to asthma successfully. Objectives This two-phased study developed and tested tailored infographics of (1) scores on the Asthma Control Questionnaire (ACQ), a self-report measure of symptom burden, and (2) pulmonary function test (PFT) results. The infographics are intended for use as communication and adherence-promotion tools in clinical interactions. Methods For both phases, participants (18+ years, English- or Spanish-speaking, persistent asthma) were recruited through two primary care clinics. In Phase I, we used a hybrid iterative participatory design process to refine prototype designs. In Phase II, we conducted individual comprehension assessment interviews with the finalized designs. Infographics were hand-tailored for each participant using their ACQ score and PFT results collected at the start of the interview. Two independent raters scored interview transcripts for gist and verbatim comprehension based on a predetermined rubric. Results The five Phase I design sessions led to final prototypes that participants (n = 21) considered appealing and easy to comprehend. All Phase II participants (n = 10) demonstrated complete gist and verbatim comprehension. Participants reacted favorably to receiving their information via infographics and expressed intentions to engage in self-management behaviors (e.g., medication adherence, smoking cessation, weight loss, and review of their care plan) in response to the information. Conclusion This study provides preliminary evidence that infographics can support comprehension of asthma control status and promote self-management intentions among adults with persistent asthma. Infographics can be programmed into electronic health records and/or standalone applications to allow for instant tailoring at the point of care.

Leprosy is a chronic and infectious disease, transmissible, which causes neural lesions in which its investigation is mandatory in Brazil because it causes decreased thermal sensitivity, touch and pain, but mainly causes loss of muscle strength in the feet and hands giving the disease a great disabling power. Therefore, this disease is of health concern and control policies have been concerned with early diagnosis and treatment of affected individuals, requiring objective, sensitive and reliable methods of measurement. Therefore, this research proposed to analyze the effectiveness of biomedical dynamometers in the measurement of handgrip strength and forceps grasping force in the hand of leprosy patients. In this context, a systematic literature review was performed considering publications in Portuguese and English from 1993 to 2019, due to the lack of qualitative research publications in recent years related to the measurement of the effects of leprosy. The results of the study showed that the dynamometers surveyed have the potential to be used as tools to measure effects and support the diagnosis of leprosy. These meters have important features such as non-invasive, easily reproduced and good accuracy, contributing to objective assessment and early diagnosis of the professional, favoring the treatment of affected patients. In addition, through this literature review, it is possible to observe the importance of handgrip strength measurement, because the delay in diagnosis and consequently in treatment generates severe physical disabilities in the hands, which are evident due to the radial, median and ulnar nerves generating limitation to perform activities and decreased work capacity.

Water scarcity and increasing labor costs of rice cultivation have prompted many agro-ecosystems in the world to adopt the direct-seeded rice (DSR) method instead of the hand-transplanting method. However, there is a downside to this approach, which is the prevalence and spread of weedy rice (WR), a troublesome weed in paddy fields that has the potential to cause a 90% loss of total yield in high-infested areas. The progression, infestation, and dynamics of WR are linked to environmental circumstances, types of rice cultivar, established techniques, and field management. WR is viewed as a critical problem, as it may prove counterproductive in rice cultivation because it causes an overall increase in the production cost of paddy harvesting. For the purpose of our discussion, a method is explored that can be used to eliminate, or at least mitigate, the spread of WR, which is the Clearfield® Production System (CPS). This method consists of imidazolinone (IMI) herbicide, Clearfield® certified seeds, and the Stewardship Guide. However, use of the CPS has been known to negatively affect the environment, as it transfers resistance traits to WR, increasing IMI persistence in the cultivated soils, and contaminating soils and water with herbicide residues. These negative environmental effects could be dealt with by using integrated weed management systems (IWMS) that include the use of all viable tools and should be incorporated with the proper Stewardship Guide to reduce the growth of herbicide-resistant WR. This review aims to elucidate information pertaining to WR infestation, the characteristics thereof, sustainable techniques for WR control, IMI herbicides, and diverse methods for the extraction and determination of IMI residues in the environment. Understanding the conspecific nature of WR serves as a baseline for constructing novel WR control strategies in the future.

Chemical using as a weed control method is the most preferred method in weed control because they are easily accessible, easily applicable and inexpensive. But, with the new environment-friendly regulations, the importance of non-chemical methods has increased all over the world. In addition, organic farm and non-chemical agricultural methods are gaining importance with increasing social environment and health awareness. Non-chemical methods, called, "alternative methods” have been one of the most popular research subjects in recent years. The physical removal or killing of weeds is usually done by hand or by means designed tools for this task, which varies from country to country. The most known modern non-chemical weed control methods are; electric current, microwave heating, superheated steam, infrared using, pneumatic system, freeze-drying, laser cutting, and fresnel lens systems. The most popular of these methods are; electric current method and microwave heating. In electric current and microwave heating methods, there are no chemical residues in soil and plants after application. It has been shown in the studies that, the microwave weed control method can destroy weeds and seeds when appropriate frequency, sufficient time and required power level are selected. Therefore, in the selection of non-chemical weed control methods, some important parameters of plant and soil should be known. The electrical and dielectric properties of plants and soil such as, electrical resistance (R), impedance (Z), dielectric constant (ε’), loss factor (ε’’), the permittivity (permeability ( and conductivity (σ) should be known especially in microwave and electric current methods. The other parameters like the age, height and density of the plant is an issue to be considered in all control methods. But, the moisture content of soil and plant may not be taken into consideration in hot water and steam applications. For the freeze-drying method, the moisture and water content of the plant and soil must also be taken into account.

Byggindustrin är idag en av våra mest olycksdrabbade branscher i Sverige sett tillantalet sysselsatta inom branschen. Olycksfrekvensen ligger idag kring 11/1000sysselsatta och år. Statistiken visar att byggindustrin har fler sjukskrivningar på grundav olyckor än andra branscher, vilket givetvis leder till större utgifter i förhållande tillde andra på denna punkt. Ett sätt att öka intresset för säkerhet och arbetsmiljöfrågorinom byggverksamheten kan vara att undersöka de ekonomiska aspekterna. Det ärtydligt att sjukskrivningar är en stor kostnad för byggföretagen men finns det egentligennågon motsättning mellan lönsamhet och säkerhet?Syftet med studien är att undersöka kopplingen mellan arbetsmiljöarbete,sjukskrivningar och kostnader inom byggsektorn. Studien utförs för att kunna ge enoberoende rekommendation på vilka åtgärder inom arbetsmiljö och säkerhet som kanminska antalet sjukskrivningar på grund av arbetsolyckor. Tanken är att undersökavilka olyckor som bidrar till flest sjukdagar och därmed störst kostnader för företagen,samt se vilka grundorsaker som går att förknippa med dessaStudien tar endast upp sjukskrivningar där bakomliggande orsak är en arbetsolycka.Det innebär att arbetssjukdommar orsakat av arbetshygieniska förhållanden intekommer att beaktas. Detta för att begränsa studien till den typ av olyckor inombyggindustrin som bidrar till flest sjukskrivningar.Undersökningen har gjorts i form av en omvärldsanalys med avsikt att samlainformation och kartlägga ämnet. Information och statistik i detta arbete har i störstamöjliga mån baserats på vetenskapligt säkerhetsställd litteratur ochmyndighetsinformation. Rapporten baseras i stor del på den nuägesbeskrivning sompresenteras i kapitel 4 som redogör bakgrund och den nuvarande situationbyggverksamheten befinner sig i när det gäller arbetsmiljöarbete, olycksstatiastik samtorsaker och kostnader för sjukskrivningar vid arbetsolyckor. I kapitel 3 presenteras denlagstiftning som i Sverige ligger till grund för arbetsmiljöarbete.I denna studie har olika undersökningar kombinerats för att få fram ett resultat på hurmycket sjukskrivningar, orsakade av arbetsolyckor, kostar. Kostnaderna baseras påarbetsmiljöverkets och försäkringskassans olycksfallstatistik samt försäkringskassanskalkylunderlag för sjukskrivning [25]. För att uppskatta kostnader för olika typer avolycksfall, undersöks hur många sjukdagar de fem vanligaste orsakerna bidrar med. Detvisar sig att den sjukskrivningskategori som kostar arbetsgivaren mest är fall från höjdoch att de åtgärder som enligt många studier förebygger detta är att ha en städadarbetsplats.Slutligen kan det konstateras att det finns kopplingar mellan arbetsplatsolyckor,sjukskrivningar och kostnader för företag inom byggsektorn. Det finns även åtgärdersom kan ge effekt på minskade sjukskrivningar, exempelvis städning och information.Utöver detta pekas även projektering ut som en punkt där anpassningar förarbetsmiljön kan göras och på så vis minska sjukskrivningar och öka lönsamheten hosföretagen.The construction industry is one of our most injurious industries in Sweden today. Theaccident frequency currently lies around 11 per 1000 employees per year. Statistics showthat the construction industry has more sick leave due to accidents than other business,which of course leads to larger cost in relation to others industrial branches in this area.One way to increase the interest in safety and work environment issues in theconstruction industry can be to examine the economical aspects. It is clear that sickleave is a big cost for construction companies, but is there really any contradictionbetween profitability and safety?The purpose of this study is to investigate the connection between work environmentand profitability for companies in the construction sector. The study is carried out inorder to give an independent recommendation on which measures within workenvironment and safety that could be used to reduce the number of sick leave occasionsdue to work accidents. The idea is to investigate which accidents contribute to the mostsick days, and to see which root causes that could be associated with these accidents.The study only addresses sick leave where the underlying cause is workplace accidents.This means that occupational diseases caused by industrial hygiene conditions will notbe taken into account, this is to limit the study to the section which contributes themost to sick leave in the construction industry .The study has been conducted as an analysis of the surrounding world with theintention of gathering information and mapping out the subject. Information andstatistics in this research have, as far as possible, been based on scientifically securedliterature and government information. The report is largely based on the complieddescription of the current situation presented in chapter 4. This chapter describes thebackground and current situation for the construction industry in regards to legislation,work environment, accident statistics as well as causes and costs for sick leave in theevent of work accidents.In this report, various research has been combined to obtain a result on how much sickleave, caused by occupational accidents, costs. The costs are based on the SwedishWork Environment Authority and the Swedish Social Insurance Agency’s accidentstatistics as well as the Swedish Social Insurance Agency’s calculation basis for sickleave. In order to estimate the costs for different types of accidents, the number of sickdays for the five most common causes of injuries were picked out. It turns out that thecause of accidents that contributes to the highest costs for the employer is fall fromhight. It was also detected that according to many studies, the most efficient way toprevent fall from hight was to have a tidy workplace.Finally, it’s concluded that there are connections between work environment accidents,sick leave and costs for companies within the construction sector. There are alsomeasures that can affect sick leave, for example cleaning and information. Beyondthese, construction design is pointed out as an area where adjustments for the workenvironment can be made and though that reduce sick leave and increase profits for thecompanies.

The purpose of this study is to determine if the use of visual tools such as a printed hand on a stick is an effective strategy in changing or eliminating undesired behavior in the classroom, particularly whole group discussions. The setting was a general education Kindergarten classroom, in a public school, of typical size and makeup. The aim of the project was to co-observe the behavior of how students answer or share information in whole group situations. The sample group consisted of students that had previously displayed difficulty in following the rules of group discussions. The findings of the study are meant to be shared with teachers in the effectiveness of using this type of strategy as a means of changing an undesired behavior in the general education classroom during class discussions. The data was collected by recording lessons at various times of the day, first without using the visual tool and then with using the visual tool. Based on observations in the recordings, data was derived noting how many times a student raised his/her hand with or without acknowledgement. Based on the data, it is safe to conclude that a considerable change in the undesired behavior was not evident.

For many people, whose first experiences using mobiles were between 2000 and 2010, it’s hard to imagine a time when friends and loved ones didn’t have mobiles or when people didn’t have access to one another after work hours. This chapter opens in California with a story of Los Angeles traffic; it was terrible, even back in 1990. Some companies wanted to make their mobile staff more productive, so they provided them with car phones—permanently mounted, fairly large phones with an antenna attached to the back window. Organizations paid for these “business tools”; and they were company property, just like a computer. During these initial years, some early adopters of new technology started bringing tools, like tablet computers and personal digital assistants, to work. This chapter sets the stage for understanding how and why negotiations for control over mobile communication emerged.

Johnson made food aid a major element of his foreign relations with several countries. He saw it as a tool, an inducement, a reward or a cudgel. As a product of Senate leadership, he knew how important the role of Congress was in approving and funding his many initiatives, and he sought to ensure that he was not viewed as a “dewy-eyed, give-away boy.” He had to be seen as a tough guy even though he was, at heart, quite a benevolent person. Critics of food aid were suggesting that it could do more harm than good when used outside narrowly defined situations requiring emergency relief. Johnson paid them little heed. He fought with Congress over control of food aid, losing several battle and winning others. His liberal stance on domestic human rights issues lost him votes among conservatives in Congress on his desired food aid reforms.

This chapter describes vibration exposure in the workplace and its adverse health consequences. Both whole-body vibration and hand-arm vibration are described. The deleterious effects from hand-arm vibration induced by power tools on peripheral nerves and small blood vessels have been documented for more than a century. Whole-body vibration increases spinal load and can contribute to muscle fatigue and deterioration of intervertebral lumbar discs. Neck pain and low back pain are also associated with whole-body vibration from various types of equipment and vehicles. The pathophysiology of various vibration-associated disorders are discussed. Prevention and control measures are described in detail. Control of whole-body vibration rests mainly on primary prevention and selection of appropriate equipment (primarily vehicle and equipment seating) to reduce whole-body vibration exposure.

How are the sense of ownership and the sense of agency related? Does one need to be able to control one’s body to experience it as one’s own? One may suggest that the sense of bodily ownership is grounded in action-orientated representations of the body. However, this agentive hypothesis cannot explain how one can experience as one’s own a rubber hand that is not under control, while not experiencing as one’s own tools that are under control. The chapter then argues that one needs to distinguish between two kinds of hot body maps: the working body map involved in instrumental actions, and the protective body map involved in self-defence. It is proposed that one experiences as one’s own the body represented in the protective body map, which represents the body that has a special significance for the evolutionary needs of the organism.

Will anti-love drugs become available? Is monogamy a ‘natural’ state for humans? Today, despite talk of sexual revolution, the ideology of possessive love has lost little of its power. But what is now at hand is the possibility of changing your individual dispositions in order to facilitate certain sorts of relationships.

Miguel La Serna’s gripping history of the Tupac Amaru Revolutionary Movement (MRTA) provides vital insight into both the history of modern Peru and the link between political violence and the culture of communications in Latin America. Smaller than the well-known Shining Path but just as remarkable, the MRTA emerged in the early 1980s at the beginning of a long and bloody civil war. Taking a close look at the daily experiences of women and men who fought on both sides of the conflict, this fast-paced narrative explores the intricacies of armed action from the ground up. While carrying out a campaign of urban guerrilla warfare ranging from vandalism to kidnapping and assassinations, the MRTA vied with state forces as both tried to present themselves as most authentically Peruvian. Appropriating colors, banners, names, images, and even historical memories, hand-in-hand with armed combat, the Tupac Amaristas aimed to control public relations because they insightfully believed that success hinged on their ability to control the media narrative. Ultimately, however, the movement lost sight of its original aims, becoming more authoritarian as the war waged on. In this sense, the history of the MRTA is the story of the euphoric draw of armed action and the devastating consequences that result when a political movement succumbs to the whims of its most militant followers.

Although the official propaganda surrounding the drug detainees in China is that of helping, educating, and saving them from their drug habits and the drug dealers who lure them into drug abuse, it is clear, according to Vincent Shing Cheng, that those who have gone through the rehabilitation system lost their trust in the Communist Party’s promise of help and consider it a failure. Based on first-hand information and established ideas in prison research, Hypocrisy gives an ethnographic account of reality and experiences of drug detainees in China and provides a glimpse into a population that is very hard to reach and study. Cheng argues that there is a discrepancy between the propaganda of ‘helping’ and ‘saving’ drug users in detention or rehabilitation centres and the reality of ‘humiliating’ them and making them prime targets of control. Such a discrepancy is possibly threatening rather than enhancing the party-state’s legitimacy. He concludes the book by demonstrating how the gulf between rhetoric and reality can illuminate many other systems, even in much less extreme societies than China.

Considering incidents that make headline news internationally, given the modern information and communication technology revolution, the facility of citizens to rapidly mobilize represents a considerable threat to autocratic survival. While the speed with which popular movements emerge has increased exponentially, and the news of their existence spreads faster and farther, civil unrest has threatened the stability and survival of dictators for centuries. The paranoia and machinations of dictators depicted in films, such as the portrayal of Ugandan dictator Idi Amin in The Last King of Scotland, while sensationalized, capture the astounding array of threats with which unelected leaders must concern themselves. On the one hand, they must worry about insider threats to their standing, such as conspiratorial plots from people within the dictator’s own circle or mutiny among government soldiers. On the other hand, dictators also must monitor threats originating from non-regime actors, such as new alliances forming among once-fragmented opposition groups or the possibility of sustained insurgency or a popular revolution. From force to finesse, autocratic leaders have developed a broad and evolving range of tactics and tools to diminish both internal and external domestic threats to their reign. The success of dictators’ endeavors to insulate their regimes from forces that might challenge them depends on accurate and reliable information, a resource that can be as valuable to the leader as would a large armory and loyal soldiers. Dictators invest significant resources (monetary as well as human capital) to try to gather useful information about their existing and potential opponents, while also trying to control and shape information emitted by the regime before it reaches the public. New information and communication technologies (ICTs), which have drawn a great deal of scholarly attention since the beginning of the 21st century—present both risks and rewards for dictators; inversely they also create new opportunities and hazards for citizens who might utilize them to mobilize people opposed to the regime. While civil unrest could encompass the full range of domestic, nonmilitary actors, there also needs to be a specific focus on various forms of mass mobilization. Historically, more dictators have been forced from office by elite-initiated overthrows via coups d’état than have fallen to revolution or fled amid street protests. Civil unrest, in its many forms, can affect autocratic survival or precipitate regime breakdown. While mass-based revolutions have been a relatively rare phenomenon to date, the actions of many 21st-century dictators indicate that they increasingly concern themselves with the threats posed by popular protests and fear its potential for triggering broader antigovernment campaigns. The ease of access to information (or the lack thereof) help explain interactions between authoritarian regimes and citizens emphasizes. The role of information in popular antigovernment mobilization has evolved and changed how dictators gather and utilize information to prevent or counter civil unrest that might jeopardize their own survival as well as that of the regime.

AbstractIn this paper, due to the importance of maintaining a secure grip with the control hand in kayaking, a simple three phase process is presented for the massive development of personalized grips which allow the improvement of this handgrip. This process consists of obtaining the 3D geometry of the paddler's handgrip by using Reverse Engineering (RE) tools, designing the grip from the obtained 3D geometry by using Computer Aided Design (CAD) tools and manufacturing the grip by using Additive Manufacturing (AM) tools. Therefore, this paper shows that the RE, CAD and AM tools available today allow the customization of products for many applications.

Predicting properties of end product from known properties of raw material is an important part of quality control in manufacturing. Main concept in this research is to reach a specified property of end product from known properties of raw material by attaining response surface designs with feasible region. The Ne20–19.21 T/inch yarn breaking strength (response, desired value 450 cNs) is acquired from cotton fiber properties (variables). The relationship between response and variables are obtained in response surface drawings and contour plots. The area showing the desired value in contour plots are colored in lilac and are intersected to obtain the feasible regions. By reading backwards from the feasible region borders, the variable value ranges are reached which will give the desired value of the response is obtained. When this information to start the yarn production is ready, the cotton lots containing these fiber property value ranges will be bought or from raw material in hand we will be read which yarn breaking strength will occur at the end of production. It was concluded that response surface designs with feasible region are quick, practical, and effective tools, provide valuable results, contribute a lot to quality control, and are beneficial in textile quality control.

This chapter traces the breakdown of the Metternichian system, from the time of the revolution of 1848 and Crimean War to the debilitating defeats by Italy in 1859 and Prussia in 1866. In the middle decades of the nineteenth century, the Habsburg Monarchy suffered defeats in a series of short, sharp wars that would bring an end to the Metternich system and pave the way for Austria’s demise as a Great Power. These changes occurred not primarily because of economic decay or the empire’s internal complexity but instead because Austria lost the tools that it had used in the past to manage the sequencing and duration of its wars. This was the result of both structural changes beyond its leaders’ control and avoidable errors and a deviation from the principles that had formerly shaped its past statecraft. Specifically, Austria’s leaders abandoned the flexible statecraft that had allowed them to control conflict sequencing and avoid isolation; rivals adopted new technologies that denied the monarchy’s armies the ability to use attrition and terrain to prolong conflict and outlast stronger militaries; and nationalism trumped treaty rights as a source of territorial legitimacy, allowing hostile polities to form in the areas that had previously served as the monarchy’s buffer zones. Deprived of its traditional strategic toolbox, Austria was forced by its strongest rival to accept cohabitation with its strongest ethnic minority and for the first time had to absorb the full costs of managing a 360-degree defensive position.

<em>Abstract.</em> —The American lobster <em>Homarus americanus </em> is usually associated with rocky substrate that provides or can be modified into shelter and that may be an essential habitat to early benthic-phase juveniles. The dependence on shelter-providing habitat not only makes possible the definition of essential habitat for lobsters but also permits the assessment of abundance based on the areal extent of habitat. Here, we describe such a habitat-based assessment, performed in response to an oil spill on the coast of Rhode Island, USA. Results from a side-scan sonar survey performed after the spill indicated that the amount of lobster habitat affected by the oil was approximately 9.8 km2 along nearly 15 km of coastline. Postspill lobster density ranged from 0.24 lobsters m22 in the impact region to 1.63 lobsters m22 in the control region. Qualitative (map contours of lobster density) and quantitative (statistical tests) approaches suggested a significant effect of the spill had been detected by our sampling. An estimate of the total number of lobsters killed was required to scale restoration efforts. We calculated the total number of lobsters in the area by overlaying contours of lobster density on a habitat map generated by side-scan sonar, then multiplying the density of lobsters in each contour interval by the area of appropriate lobster habitat (cobble and boulder) in the contour interval. To calculate loss, we subtracted postspill abundance from prespill abundance. Prespill density was estimated to be 1.76 m22, which is an adjusted average of airlift samples taken at six Rhode Island sites four months prior to the spill. Calculations of loss based on habitat-specific density estimates were adjusted to reflect undersampling. The loss was estimated to be to be 9.0 × 106 lobsters. Variability associated with this loss estimate is large; 95% confidence intervals estimated that between 6.7 × 106 and 15.6 × 106 lobsters were lost. The calculated loss was very sensitive to changes in prespill density estimates; a change of 0.1 lobsters m22 resulted in a change of 0.75–0.9 × 106 lobsters lost. Habitatbased assessment of lobster population size is possible but requires detailed habitat maps and accurate density estimates. Natural variability and sampling limitations give such assessment a wide range of possible values. Nevertheless, the airlift sampling technique, together with sidescan sonar maps of habitat, could provide a powerful tool for estimating the abundance of inshore lobsters.

The chapter wants to take into consideration the progressive loss of identity and authenticity of the city of L’Aquila, located in the Abruzzi region of central Italy about a hundred kilometers east of Rome, after the earthquake of 2009. Described as “a small Florence of the Italian Renaissance”, L’Aquila is nestled in a basin surrounded by mountains, with what was a fully recognizable identity until the devastating earthquake which took place on April 6, 2009, the night after Palm Sunday. After those violent seismic shocks, repeated in 2016 and 2017, there was a progressive demographic depopulation, since the historic center of the capital and that of the hamlets have been closed and declared a “red zone”. The population, especially the younger ones, no longer recognizes themselves in their place of origin, and many people have preferred to leave. Authenticity, both material and formal (of the urban form) is also increasingly diminishing. Today the image of the city, which had been handed down over centuries, is lost. Immediately after the 2009 earthquake the city was closed and barred, preventing residents from remaining in their homes, even in the less damaged ones. The historic center was isolated and emptied, occupied by the military forces and the Fire Brigade. Contrary to any common sense, instead of immediately carrying out consolidation and restoration work (especially with regards to the more characteristic minor structures), it was decided to begin with long and expensive shoring and scaffolding installations. A forest of props and tie rods that secure the walls and draw imaginative and imposing patterns, thus postponing sine die urgent works. With the forced expulsion of the inhabitants which has now lasted for nearly seven years, the younger generation particularly, is showing (perhaps unconsciously) more and more indifference and detachment from their roots in the historic center. As time passes social and economic interest (as well as those of identity) in returning to their past houses fade. They prefer to pass time elsewhere, either in the suburbs where anonymous shopping centers have mushroomed, or in other cities (in some aspects this has been favored by the possibility of obtaining funds for the purchase of houses outside the municipality). This is why one can speak of a double loss of identity and continuity. The topic should, therefore, be approached from a twofold point of view: identity and continuity. Identity meaning that which transmits the original model and characteristic of place and the inhabitants; and continuity meaning that which allows you to remain permanently in the same place with a stable dwelling. We also find a dual meaning in lasting continuity; the people (inhabitants), and the space and form of architecture. Identity and continuity are also reflected in lifestyle, as well as in details, materials, colors and common feelings. A ‘sentimental heritage’ as well as a material one, which is now lost. There is, therefore, a twin theme: that of the continuation of archetypes, and that of housing models in which the population recognizes itself. Today in L’Aquila, identity has disappeared. The inhabitants no longer appear as protagonists, but are reduced to extras, to mute actors against the backdrop of an incomprehensible scene. Even if the search for a lost identity and continuity may now seem an unreal or utopian goal, it should have been the opposite; they should have been the priority and gone hand in hand with the reconstruction. At the end, the various restoration and reconstruction criteria for the survival of what remains of the city will also be examined.

Upper limb amputations seriously affect a patient's life by restricting their ability in performing various tasks. Prosthetic hands are considered the primary method to reinstate the lost capabilities of such amputees. However, the presently available prosthetic devices are unable to fulfill the requirements of users due to their excessively high cost, limited functionality, heavy weight, unnatural operation, and complexity. This article presents an affordable and simple control-based myoelectric hand for transradial amputees. The hand setup mainly consists of a self-designed surface electromyography (sEMG) sensor, a microcontroller unit and a five-fingered, intrinsically actuated 3D printed hand for dexterous operations. The developed hand was implemented with proportional control scheme and was successfully tested on five amputees (with missing lower forearms) for performing grasping activities of different objects. Further, the closing time and grip force at the fingertips were also determined for the hand to compare its performance with the commercially available hands.

This chapter considers the progress of direct European rule in Islamic countries during the late nineteenth century. Whereas France was concerned with constituting a huge African bloc with the primary and avowed motive of preserving its rank as a major power, Great Britain confined itself to the desire to control the Indian route. Meanwhile, the Ottoman Empire embarked on a policy of reconsolidating the empire on the basis of a modernizing Muslim authoritarianism. In an empire where the share of the Muslim population had grown considerably, with the loss of the Balkan provinces and the continuous influx of Muslim refugees, there was a revival of caliphal as well as Islamic influence. At the same time, the authorities continuously developed the tools of modernity.

Loss or impairment in the ability of muscle movement or sensation is called Paralysis which is caused by disruption of communication of nerve impulses along the pathway from the brain to the muscles. One of the principal reasons causing paralysis is Spinal Cord Injury (SCI) and Neurological rehabilitation by using neuro-prostheses, based on Functional Electrical Stimulation (FES) is extensively used for its treatment. Impaired muscles are activated by applying small amplitude electrical current. Electromyography (EMG), the recording of biosignals generated by muscle activity during the application of FES can be used as the control signal for FES based rehabilitative devices. This method is predominantly used for restoring upper extremity functioning (wrist, hand, elbow, etc.), standing, walking (speed, pattern) in stroke patients. FES, collaborated with conventional methods, has the potential to be utilized as a useful tool for rehabilitation and restoration of muscle strength, metabolic responses etc. in paralyzed patients.

Exposure to high noise levels may be the most common occupational hazard. Recent estimates suggest that as many as 30 million Americans are exposed to noise levels greater than the current safe limits for workplaces. At current durations of exposure, it is expected that 25% of these workers will develop permanent, noise-induced hearing loss. In many of these industrial environments, high levels of vibration also exist that can lead to several injuries and ailments. To address the adverse effects associated with the use of high noise emission impact tools, a study was initiated to develop and evaluate alternate tool designs that reduce the potential for hearing loss and vibration-related injuries. Recent work has focused on integrating advanced engineering polymers (composites) into tool designs for the purpose of eliminating direct metal-to-metal impact. This approach has several significant performance advantages including reduced operator discomfort due to hand-arm mechanical shock, reduced noise, and less danger from flying metal fragments. To quantify sound emission characteristics of these new designs, continuous sound pressure, maximum sound pressure, and maximum sound pressure level were measured using an array of five precision microphones each located 1 meter from the tool. Data was sampled at 40 kHz while test subjects operate both pneumatic tools and hand-struck tools. Frequency spectra of the sound pressure signals were examined for all tool treatments, and indicate that the addition of a polymer insert between metal impact components significantly reduces noise emission, especially at higher frequencies. Similar reductions were observed in vibration transmission in the hand and arm. As a result, tools that integrate polymer-based components may be operated for longer daily exposure times without inducing hearing loss or vibration-related injuries. Data from this study may also help auditory and ergonomic specialists in understanding impulse noise characteristics and exposure.

Abstract Human hands play a key role in almost all activities of daily living (ADLs) because it is an incredibly versatile tool capable of complex motion. For individuals who have had a complete loss of the hand, the ability to perform ADLs is impaired. Effective prosthetics accurately simulate the movements of a human hand by providing a high number of degrees of freedom, an efficient control system, and an anthropomorphic appearance. In this paper, the design and construction process of a highly anthropomorphic soft robotic prosthetic hand is outlined. The design specifications of the hand are based on feedback from current and former prosthetic users. The hand endoskeleton was 3D printed using fused deposition modeling techniques and was enclosed in a silicone coating modeled, after a real human hand. The hand presents anthropomorphic design in its realistic bone shapes and in its external covering that is like skin in texture and mechanical properties. The hand utilizes the flexibility of silicone instead of antagonistic tendons which would otherwise add complexity and weight to the prosthetic design. The prototype also includes adduction/abduction of the fingers, which is a common omitted movement in other prosthetics. Testing showed that the hand is capable of effective power and precision grasping.

We present the paradigm of natural and exploratory shape modeling by introducing novel 3D interactions for creating, modifying and manipulating 3D shapes using arms and hands. Though current design tools provide complex modeling functionalities, they remain non-intuitive and require significant training since they segregate 3D shapes into hierarchical 2D inputs, thus binding the user to stringent procedural steps and making modifications cumbersome. In addition the designer knows what to design when they go to CAD systems and the creative exploration in design is lost. We present a shape creation paradigm as an exploration of creative imagination and externalization of shapes, particularly in the early phases of design. We integrate the capability of humans to express 3D shapes via hand-arm motions with traditional sweep surface representation to demonstrate rapid exploration of a rich variety of fairly complex 3D shapes. We track the skeleton of users using the depth data provided by low-cost depth sensing camera (Kinect™). Our modeling tool is configurable to provide a variety of implicit constraints for shape symmetry and resolution based on the position, orientation and speed of the arms. Intuitive strategies for coarse and fine shape modifications are also proposed. We conclusively demonstrate the creation of a wide variety of product concepts and show an average modeling time of a only few seconds while retaining the intuitiveness of communicating the design intent.

Abstract Due to their high power density, hydraulic systems are increasingly adapted for human scale devices. For example, commercial and utility electricians use electrohydraulic cutting and crimping tools, rather than human powered tools, to cut and crimp wires that exceed 25mm in diameter. These tools greatly reduce worker-related fatigue and strain-type injuries. To improve electrohydraulic tool technology, there is a need to increase the number of applications from a single battery charge. This paper develops a high fidelity nonlinear lumped parameter model of an electrohydraulic crimping hand tool used by professional electricians. The eleventh-order model can predict tool performance with an average error of 6.9% and 4.4% with respect to the maximum energy consumption and crimp time, respectively. Simulation studies were conducted to investigate reducing the energy consumption of the tool. An independent parameter sweep was performed on the pump piston diameter. The gear ratio was a dependent parameter linked through the maximum motor torque. Increasing the pump piston diameter while increasing the gear ratio was shown to decrease the energy consumption of the tool during crimping applications. Simulations suggest that up to 30% energy can be saved per crimp by increasing the pump piston diameter and gear train ratio.

A conventional combustion tuning method for a gas turbine needs more than 24 hours with lots of human labor. In addition it is hard to certify whether the plant is optimized because the conventional tuning is based on human decisions and subjective empirical data over a long time. In this study we developed a combustion tuning technology using six sigma tools (CTSS) to effectively meet the increasingly stringent NOx regulations and to save combustion tuning time. CTSS was conducted in five steps—define-identify-design-optimize-verify (DIDOV). First, the NOx reduction target was defined (Step 1, define), the current status of the plant was diagnosed (Step 2, identify), and the vital few control parameters to achieve the defined target were determined by analyzing the correlation between the control parameters and NOx emissions (Step 3, design). For the next step, the optimum condition was derived from one of the six sigma tools (Step 4, optimize), and finally the optimum condition was verified by applying the condition to the gas turbine combustion (Step 5, verify). As a result of CTSS, averaged NOx emissions were reduced by more than 70% and the standard deviation was improved by more than 60%. These results show that CTSS is a potential tool for enhanced reliability of plant operations and scientific method for quick and exact combustion tuning.

Abstract Prolonged exposure of the human arm to vibrations from hand-held impact (HIM) tools can be hazardous as such, it is important that the level of vibration suppression in HIMs is improved. This paper sought to address this issue by studying a model of the hand-arm system (HAS) coupled to a HIM which is also coupled to a nonlinear tuned vibration absorber inerter (NVAI). The HAS is modelled as a 2-DOF system coupled to the HIM at a single point. The HIM is modelled as an oscillator with linear damping, and both linear and nonlinear stiffnesses. The nonlinear stiffness of the HIM is introduced to represent the nonlinearities introduced by the vibro-impact dynamics of the HIM. After obtaining the equations of motion for the system, an analytical solution is obtained using the harmonic balance method. The analytical solution is validated using direct numerical integration and the results show very good agreement. The performance of the NVAI is compared to those of the classical nonlinear and linear vibration absorbers. Parametric study is carried out to examine the role of key design parameters, such as the damping of the absorber, nonlinear stiffness of the HIM and inertance of the NVAI, on the performance of the NVAI.
