DM is a widespread condition that affects a substantial portion of the global population, causing high morbidity and mortality rates. The prevalence of this major public health crisis is predicted to increase in the forthcoming years. Although, several drugs are available to manage DM, these are associated with adverse side effects, which limits their use. In underdeveloped countries, where such drugs are often costly and not widely available, many people continue to rely on alternative traditional medicine, including medicinal plants. The latter serve as a source of primary healthcare and plant-based foods in many low and middle-income countries. Interestingly, many of the phytochemicals they contain have been demonstrated to possess antidiabetic activity such as lowering blood glucose levels, stimulating insulin s...

They apply to our dealings with each other, with animals and the environment. They should govern our interactions not only in conducting research but also in commerce, employment and politics. Ethics serve to identify good, desirable or acceptable conduct and provide reasons for those conclusions. Fair subject selection is the first and foremost concern which must be ensured before initiating a research project. Which subjects may enroll in the research is determined by the study's inclusion or exclusion criteria. One of the important aspects of fair subject selection is to have an oversight system through International Review Board (IRB) to review to conduct the research and to have approval whether subject selection is fair or not.

Monitoring water level of a water source, such as dams, water tank or bore-well plays a key role in agricultural management and development. This work aimed at development of an automatic water level indicator. Developing a water level indicator can be helpful to reduce the water wastage. The major components used for the development of the water level indicator were Arduino board, sonar sensor, buzzer, LED lights. The automatic water level monitoring system was realized usilzg a sonar sensor attached to an Arduino Uno to process the analog signal coming from the sensor into a useable digital value of distance also we added a buzzer in this system so that we can be aware about the increasing level of water.

It enables us to understand the nature of the atmosphere. Precise weather forecasting is one of the greatest challenges in the modern world. Unlike traditional methods, modern weather forecasting involves a combination of computer models, observation (by use of balloons and satellites) and patterns recognition along with various trends. Forecasting can be made accurately and precisely by the proper application of these methods. For forecasting various kinds of computer methods are used and these methods are related to various complex formulas. Researchers have done many things to establish a relationship of recent (input) data and target data which is linear. But practically the relationship is nonlinear. After establishing the nonlinearity, many models have been made to get future weather data. As the weather data is nonlinear, Artificial Neural Network (ANN) has become an effective way of predicting weather data precisely and accurately. Neural Network is a system that can be trained with certain input and output. It creates its own structure based upon how it is trained. In this paper we predicted weather data for a particular month of a season and compared the result for different functions and training method of ANN.

A practical illustration of that is the establishment of the Governance Innovation Unit under the prime minister’s office and the A2i at the ICT division, the first innovation laboratory of its kind in the world. At the same time truly remarkable are the innovations achieved with the help of technology and information in the public sector, especially for a young country such as Bangladesh. Usage of technology is hoped to reduce the rigidity of service delivery, increase effectiveness and efficiency, and also at the same decrease the travel, cost, and visit for the service recipients. Institutionalization of these innovations is vital for making the innovations replicable throughout the whole sector and also for making them sustainable. This paper aims to examine and understand the state of institutionalization of technological innovat...

Motivated by the results of Bliss and Gul (2012), this study employs a longer and comprehensive dataset reexamine the association between PCFs and the cost of debt in Malaysia. First, PCFs are associated with lower cost of debt. Second, CEO's duality is associated with higher cost of debt. Third, higher audit committee independence leads to lower cost of debt. Although the results are more intuitive and in line with established theories and prior evidence, it differs with Bliss and Gul (2012) findings. Overall, this study provides further evidence that studies examining the influence of political connections on firm outcomes should employ a longer period of study in order to capture the dynamic changes in leadership.

They are useful on account of their relation to the Gelfand-Zetlin algebra and the Young-Jucys-Murphy elements, both of which are important objects in the Okounkov-Vershik approach to the representation theory of the symmetric group. We examine all of these results over the course of the thesis. Degenerate Bethe operators are a new, albeit promising, topic. Therefore, we include proofs for previously-unproven basic aspects of their theory. The primary contribution of this thesis, however, is the computation of eigenvalues and eigenvectors of all the degenerate Bethe operators in sizes 4 and 5, as well as many in size 6. For each partition λ ` k we compute the operators B`j , where ` + j ≤ k , and give the eigenvalues and their corresponding eigenvectors in terms of standard Young tableaux of shape λ. The number of terms in the degenerate Bethe operators grows ve...

It is because of the growing portion of IoT devices for consumers. In order to boost the productiveness and authenticity of metropolitan framework persistent attempts are being made in the field of IoT. Traffic congestion, Road blockage, restricted parking and road safety are some issues that has come forward in IoT. In this paper, a single platform smart parking system integrated to cloud based on IoT is presented. The proposed Smart Parking system comprises certain inventive technologies that can administer car parking automatically. This research also proposes a prediction algorithm to improve efficiency of searching and booking of vacant parking spot and also implements a prototype with Wi-Fi access on a single platform established on Arduino where using a smart phone the system and the vehicle will get an interface to validate the workability of the proposed system.

Coxeter asserts that a certain quotient B(m, n) of the braid group B(m) on m strands is finite if and only if (m, n) corresponds to the type of one of the five Platonic solids. If k is a knot or virtual knot, one can study similar quotients G(k, n) for the corresponding knot group. We identify a class of long virtual knots k for which G(k, n) is infinite for n ≥ 2. The main feature of these long virtual knots is that their Wirtinger complexes are non-positively curved squared complexes.
