Bauxite waste sludge is quite dangerous when polluted into the surrounding environment. The number is increasing with the higher mining production. The utilization is still not maximized hence it is unbalanced to the increasing number, and it is necessary to use on a large scale. Sub-grade soil could use a lot of bauxite waste sludge but in reality, this waste is unsafe to use and its characteristics are mud the requirements of bearing capacity according to the AASHTO and USCS Classification unfulfilled. This study aims to determine the effect of the use of probiotic bacteria in bauxite waste on its physical characteristics and pH value. This experimental research method develops test objects according to ASTM standards with the same weight of bauxite waste and variations in the number of probiotic bacteria, namely 25 ml, 50 ml, 75 ml, and 100 ml and the incubation time of bacteria is 7 days, 14 days, 21 days, 28 days, 35 days, and 42 days. The results showed that the test specimens with more bacteria and longer incubation times resulted in lower pH values and physical characteristics that fulfilled the requirements for sub-grade soil.

This paper proposes a solution to facilitate maintenance activities associated with stand-alone solar photovoltaic installations in our developing countries. The autonomous photovoltaic solar installation is not connected to the electricity distribution grid. It meets the electricity needs on the one hand, of those who are too far away and who do not have access to the distribution grid. On the other hand, those who wish to overcome the constraints of connection to the electrical distribution grid. Our work focuses on the capitalization of knowledge in maintenance activity. The goal is to propose a model capable of helping maintenance technicians during their interventions by providing them with knowledge elements that will be drawn from a knowledge base. This knowledge base is built from the knowledge collected during previous maintenance activities in a given solar photovoltaic installation.

The observation of food intake and ingestive behavior remains an open problem that has significant implications in the study and treatment of obesity and eating disorders. A novel method of fusing a sensor and pattern recognition method was developed to detect periods of food intake based on non-invasive monitoring of chewing. A surface-type EMG electrode was used to capture the movement of the lower jaw from volunteers during periods of quiet sitting, and food consumption. These signals were processed to extract the most relevant features, identifying from 4 to 10 features most critical for classifying the type of food consumed. Fuzzy classifiers were trained to create food intake, detection models. The simplicity of the sensor may result in a less intrusive and simpler way to detect food intake. The proposed system is implemented using LabVIEW. The proposed methodology could lead to the development of a wearable sensor system to assess eating behaviors of individuals and also to calculate the quantity of food intake.

In this modern era are so many beauty products on the market ranging from legal and illegal, many also now servicing beauty clinics and doctors growing beauty with sophisticated tools. Oriflame became one of the beauty products that exist in Indonesia trying to offer products that are natural and provide business opportunities with cosmetic. Oriflamme cosmetic is one beauty product that is widely used in Indonesia because of this cosmetic can be used for all skin types especially for tropical areas such as material natural Indonesia.kosmetika from Sweden. Some ingredients of cosmetics Oriflame among blueberry, horse chestnut, yarrow, iris, palm, birch, cloudberry, apples and so forth. Oriflamme itself not only produce cosmetic to be marketed but Oriflame also provides land for business in Oriflame, so as a member of Oriflame not only able to use the product also can take advantage of the opportunity to become a career.

New numerical results are generated for in-plane compressive biaxial buckling which serves to quantify the effect of material anisotropy on buckling loading. The coupling effect on buckling loads is more pronounced with the increasing degree of anisotropy. It is observed that the variation of buckling load becomes almost constant for higher values of elastic modulus ratio.

Now a day’s android applications are making our life much easier and happier. We always ensure that device that contains all applications should be always with us and secure anytime anywhere. In this journal I developed an android application to find your mobile phone using other devices when you lost it nearby, using text message and unique code generated on both devices. The application is designed in such a way that we can ring phone even when it is on silent mode. For developing this application I proposed a method, I simply divided code modules of Android functions, so that we can able to invoke each module of android device separately to ring, vibrate and other function. Each android module will take the device administrator permission to modify android function using application.

Standing is a normal posture during working in industries, some jobs even make it mandatory to stand while working. Standing is natural and itself doesn't pose a specific health risk. But standing for a very long duration has an immense share in many health complications. The aim of this study is to determine which type of footwear is healthier to wear while standing for long periods. Five physically fit participants ( ) were chosen from lthe ive industrial environment. All the five participants participated in this study without disturbing their usual work as ma achine operator. Photo-plethysmography (PPG) was used to collect continuous heart rate information from each participant. Each participant was observed for six hours each day for two consecutive days, wearing different footwear each day. The information collected was used to calculate total energy expenditure during the experimentation period.
