Poor quality lighting not only impedes astronomy research and our right to see a starry night sky, but creates safety issues, affects human circadian sensitivities, disrupts ecosystems, and wastes billions of dollars/year in energy consumption. It also leads to excess carbon emissions. How do you change the mindset of society that is used to turning night into day? You educate the next generation on quality lighting. As an outcome of the International Year of Light 2015, the U.S. National Optical Astronomy Observatory’s Education and Public Outreach group has produced a Quality Lighting Teaching (QLT) Kit. The kits are designed around problem-based learning scenarios. The kit’s six activities allow students to address real lighting problems that relate to wildlife, sky glow, aging eyes, energy consumption, safety, and light trespass. The activities are optimized for 11-14 year olds, but can be expanded to younger and older. All materials are in English and Spanish. Most of the activities can be done within in a few minutes during class or afterschool in the form of stations or as stand-alones. Everything one needs for the six activities is included. Tutorial videos on how to do the activities can be found at www.noao.edu/education/qltkit.php. Ninety-two kits have been distributed to 32 countries with the help of SPIE–The International Society for Optical Engineering, CIE–International Commission on Illuminations, OSA–The Optical Society, IDA–the International Dark Sky Association, and the IAU OAD–Office of Astronomy Development. Highlights from the initial program evaluation will be discussed.

The article analyzes the complex state of the modern legislative regulation of quality and product safety issues in the context of ensuring consumers’ rights to the proper quality of goods (works, services). It is stated that in view of the variety of different properties that make up the notion of quality, the most important are the defects, which are capable of damaging the life, health, or property of the consumer, that is, the defects, which indicate that the goods are dangerous. The safety of goods works, and services as a legal category are of particular importance and is one of the functions of the state to ensure public safety. State measures of influence on manufacturers and sellers of goods, persons who perform work and provide services should be aimed at ensuring the protection of fundamental civil rights. In most cases, these are imperative requirements for safety, which are approved by special legal acts, as well as measures of state supervision and control to ensure the safety of manufactured goods, works, and services. The legislator, when defining security, uses the term “safety of goods (works, services)”, but it would be advisable to carry out graduation of these concepts since the safety of goods is a state of goods that allows it to be sold, used, stored, transported, disposed of without harm for life, health, the property of the consumer and the environment in normal conditions, and the safety of works and services is the quality of protection of the legal rights of the consumer in carrying out the activities of persons who perform work and provide services, danger to life, health, the property should not manifest itself either in their implementation and providing or later. It is noted that quality requirements should be made mandatory when designing production specifications. It is stated that in order to ensure the effectiveness of legal regulation, the safety of a product, work, or service must be considered as a full-fledged property within the legal notion of quality. It is concluded that product safety is an integral feature of any product, work, and service, acting as an integral element of the quality category. Lack of safety features indicates that the product is of poor quality. Keywords: quality, safety, proper quality, improper quality, specifications, consumers.

In 1975, the U.S. Department of Health reported that more than half of the individuals in hospitals are there for self-induced reasons related to poor quality lifestyles: lack of exercise; excessive weight; tobacco, alcohol, and drug abuse; and poor stress management (Beeler, 1987). As many as one-third of the 500,000 deaths from cancer in the U.S. each year can be attributed to poor diet. Another third of cancer deaths - mostly lung, bladder, and pancreatic - are caused by cigarette smoking. Other cancers show links to excessive alcohol consumption (Weiss, 1992). The U.S. Surgeon General, who analyzed factors contributing to the ten leading causes of premature death and disability in the U.S., says nearly 50 percent are related to unhealthy behavior (Wolford, Wolford & Allensworth, 1986).

Reducing Energy

Energy consumption by the dairy food industry in the United States constitutes 10% of all energy consumed by the U.S. food industry. Reducing energy consumption in cooling and refrigeration of foods plays an important role in meeting the challenge of the energy crisis. Hardening is an important and energy-intensive step in ice cream manufacturing. This work presents Finite Element Method (FEM) investigation of the ice cream hardening process, aiming to provide insight and guidance for energy savings in ice cream manufacturing. Effects of container shape and dimensions, container layers, and heat transfer boundary conditions on energy consumption for hardening of ice cream were investigated.

Nowadays energy saving is a topical issue due to increasing fuel costs and this aspect is amplified by more stringent emissions regulations that impact on vehicle development. A recent study conducted by the U.S. Department of Energy shows that about five percent of the U.S. energy consumption is transmitted by fluid power equipment. Nevertheless, this study also shows that the efficiency of fluid power averages 21 percent. This offers a huge opportunity to improve the current state-of-the-art of fluid power machines, in particular to improve the energy consumption of current applications. These facts dictate a continuous strive toward improvements and more efficient solutions: to accomplish this objective a strong reduction of hydraulic losses and better control strategies of the hydraulic systems are needed. In fluid power, there exist many techniques to reduce/recover energy losses of the conventional layouts, e.g. load sensing, electrohydraulic flow matching, independent metering, etc. One of the most efficient ways to analyze these different layouts and identify the best hydraulic solution is done through virtual simulations instead of prototyping, since the latter involves higher investment costs to deliver the product into the market. However, to build a fluid power machine virtual model, some problems arise relative to different aspects, for instance: loads on actuators (both linear and rotational) are not constant and pumps are driven by a real engine whose speed depends on required torque. Furthermore, it is important to achieve higher level of detail to simulate each component in the circuit: the greater detail, the better the machine behavior is portrayed, but it obviously entails heavy impact on simulation time and computational resources. Therefore, there is a need to create mathematical model of components and systems with sufficient level of detail to easily acquire all those phenomena necessary to correctly evaluate machine performance and make modifications to the fluid power component design. In this context, a hydraulic proportional valve PVG 32 by Danfoss is taken as an object of study, its performance is analyzed with suitable mathematical model and simulation is done to observe closeness of a model to the laboratory experiment.
