With an expeditious increase in the vehicle transport in the major cities, it has become more difficult to find the free parking space to park the vehicles. Constant rise in the number of vehicles on the roads has led to increase in the unwanted traffic, drivers frustration, delay in the transportation and increase in the noise and air pollution. Due to lack of proper knowledge of parking space, it has become unable to utilize most of the nearby parking space. This work proposes an innovative approach to guide the vehicle drivers to the parking space using Hierarchical Wireless Sensor Networks. A three sensors per parking slot based technique is used to distinguish the type of parked vehicles and to find the free parking slots in the parking area. Free, partially-occupied and occupied parking slot states information is stored at the Parking Server in the form of parking location and the parking area layout with parking slot states marking on it. Parking Server makes the parking information available to the vehicle drivers by the mean of web and mobile applications for guiding vehicles for parking. The results show that the parking detection with multiple passive sensor nodes per parking slot system is more energy efficient and vehicle parking detection is as accurate as the single active sensor per parking slot system in the existing parking designs.

Acute bronchitis is inflammation of the main air passage to the lungs generally follows a viral respiratory infection. Children generally suffer from acute bronchitis at any stage. Fumes, dusts, decreased immunity, indigestion, viral infections are some causes due to which air passage get inflamed and irritated. Acute bronchitis is a clinical syndrome produced by inflammation of the trachea, bronchi, and bronchioles. In children, acute bronchitis usually occurs in association with viral respiratory tract infection. Acute bronchitis is rarely a primary bacterial infection in otherwise healthy children. In modern therapies using excessive expectorant, antihistaminics, and cough suppressants causes certain side effects and has no roll in rejuvenating the respiratory system. Unicough is a herbal remedy with the herbs which acts as a mucolytic and mild expectorant by its smoothening effect which helps in easy evacuation of cough and rejuvenate the respiratory passages. Current open labeled study on forty four children of acute bronchitis showed significant improvement after first and second week of the treatment in all associated symptoms which proves that Unicough syrup is a safe and effective remedy for acute bronchitis. 3 . Antibiotics are commonly prescribed, this type of therapy remains controversial, particularly since only half of all exacerbations are bacterial in origin, the rest being viral or chemical. Thus some believe that antibiotic therapy of acute exacerbation of bronchitis is an abuse of antibiotics, and can contribute to antimicrobial resistance 4 . The natural approach to treating bronchitis avoids creating new disease problems. It involves two goals: stimulating the normal processes that expel mucus, and stimulating the immune system to deal with viral infection. Expectorant herbs increase the fluidity and volume of phlegm, and stimulate cough. They are not cough suppressants, since cough suppression traps phlegm in the bronchi and lungs 5 . Unicough is a herbal remedy with Khaira Chhal (Acacia catechu),Vasakapatra (Adhatoda vasika), Vach (Acorus calamus), Elaichi (Elettaria cardamomum), Nagkeshar (Mesua ferrea), Talispatra (Abies webbina), Tulsi (Ocimum scantum), Dalchini (Cinnamomum zeylanicum), Sounth (Zingiber officinale), Pippali (Piper longum), Kababchini (Piper cubeba), Mulethi (Glycyrrhiza glabra), Somlata (Ephedra gerardiana), Dhatura panchang (Datura metel), Ajowan sat (Thymol), Pudina sat (Menthol). All these ingredients act as a smoothening, expectorant, bronchodilator and also improve the metabolism. This was an open labeled, non comparative study in the patients of acute bronchitis for the period of 15 days.

Purpose: Urinary stones have occupied a major place in the urological practices. It is one of the most common and painful urologic disorder of the urinary tract. Generally, the age between 20 to 40 years is more prone to it. As it has a high rate of recurrence, it is affecting economy and general health of the people Method: This study was a prospective, placebo controlled, double blind study. The study incorporated a matched pairs design. Each patient has received a single treatment of either the control or investigational product (UNEX). The goal was to enrol approximately 80 patients in order of having 60 patients (30 in each group) to complete the trial and provide data for analysis. Result: Total 72 patients were enrolled in the study, out of which 64 patients completed There was extremely significant results obtained in case of urine analysis of patients for infection, bacteriuria and haematuria, at the end of 6 months, value as compared to before treatment value the study, With the treatment with UNEX capsule, significant relief was observed in case of X ray KUB shows that renal calculi disappeared in 18 patients at the end of 6 months out of 32 patients, whereas USG of renal pelvis shows disappearance in 16 patients out of 32, which is extremely significant as compared to before treatment value where 32 patients showed presence of renal calculi. However, in placebo, only three patients out of 32 showed absence of renal calculi at the end of 6 months of treatment. Conclusion: Considering the excellent results of the clinical trial, it can be concluded that UNEX is effective in the treatment of Ureteric calculi, without producing any undesirable side effects. No clinically significant adverse reactions were reported or observed, the clinical trial of UNEX, an Ayurvedic preparation, has proved its efficacy and safety in upper ureteric calculi.
