Road logistics refer to the movement of various commodities from one place to another. Road is the most important mode of transport for freight and about 74 percent of total global freight is transported by road. It offers many advantages over other modes of transportation such as costefficiency, easy to track, fewer idle periods, door-to-door delivery, quicker delivery time, safety of the cargo, and the ability to use different routes. With these proven advantages, the Trucking industry is introducing some major technological advances such as ICT, computerized vehicle routing, active traffic management, and online freight exchange.

Breath analyzers are devices used to detect the presence of different compounds in an individual's breath sample. Breath analyzers are most commonly used to measure the blood alcohol content in a breath sample. These devices are a major tool in convicting offenders of drink and drive offenses. Individuals are also adopting breath analyzers for their personal use. Other applications of breath analyzers include identifying drug abuse and detecting diseases such as asthma and tuberculosis.

A printed battery is a thin and flexible battery composed of zinc (anode) and manganese dioxide (cathode) and is printed on a recyclable plastic. The output voltage from the battery is 1.5V with a peak drain current of 1mA. Printed batteries are used mainly for short-lifetime and low-power-source applications. As these batteries are produced using eco-friendly materials, they can be easily disposed of with household waste. The most important feature of a printed battery is that it is inexpensive. Printed batteries are used in a variety of devices such as passive RFID tags, temperature sensors, cosmetics and pharmaceuticals, interactive packaging, and smart cards.

COPD covers various progressive lung diseases including emphysema, chronic bronchitis, refractory (non-reversible) asthma, and some forms of bronchiectasis. It is a serious condition that restricts airflow in the lungs and is characterized by increasing breathlessness. The exact etiology of COPD is not understood; however, most cases of COPD are caused by genetic factors and by inhaling pollutants such as smoking, fumes, and chemicals. As the disease develops, the symptoms tend to get worse if an infection occurs in the lungs. While the disease cannot be cured, it can be managed and treated.

H1N1 influenza (zoonotic) is an infectious disease in humans caused by the H1N1 virus. The H1N1 virus infects the nose, throat, and lungs of the host. It is an RNA virus and a type of influenza A virus belonging to the Orthomyxoviridae family. Influenza A viruses can infect different animal species such as humans, swine, birds, seals, and horses. On the basis of the antigenicity of their surface glycoproteins, influenza A viruses can be subdivided into neuraminidase and hemagglutinin. The hemagglutinin component is used by the virus to bind to host cell receptors, thereby facilitating viral entry into the host cell. The neuraminidase protein enzymatically cleaves terminal sialic acid residues from mucins, thereby allowing the virus to reach underlying cells in the respiratory tract. The elderly, young children, and people with medical conditions such as liver disorders, blood disorders, kidney disorders, chronic lung disease, asthma, and neurodevelopmental and neurological conditions are more susceptible to the infection. Influenza vaccines are administered for active immunization against the influenza virus, conferring protection against the disease. Vaccination of high-risk groups prevents unnecessary hospitalizations and premature deaths because of the disease.

Hydro-pumped storage is an altered use of conventional hydropower technology to store and manage energy. Hydro-pumped storage projects store electricity by circulating water between an upper and lower reservoir. The electrical energy is converted to potential energy and stored in the form of water at an upper elevation. Pumping the water uphill for temporary storage recharges the battery, and during periods of high electricity demand the stored water is released back through the turbines and converted back to electricity as in the case of a conventional hydropower station. Hydro-pumped storage cycle efficiencies exceed 80 percent, unlike other energy storage and thermal technologies that have lower efficiency.

A PV inverter is a device that converts the DC current from solar panels into AC current of the required frequency, which is then supplied to the electric grid. The device uses the MPPT technique to extract the maximum amount of power from an array of solar panels. Though it functions just as a simple converter, a PV inverter is the most essential part of a solar power plant.
