Activated charcoal derived from Moringa oleifera, Manihot esculanta, Carica papaya are efficient for waste water treatment and dye removal. Adsorption techniques are used to remove the non-bio degradable pollutants. The produced carbon was exemplified using Scanning Electron Microscopy and Fourier Infrared spectroscopy. The discoloration rate was higher at an optimum pH of 5 for all three samples and at an adsorbent dosage of 0.02g/100ml of effluent and the equilibrium was obtained in 10 minutes. Thus, the adsorbents have the prospective for realistic applications. Adsorption isotherms was evaluated by the Freundlich, Langmuir isotherms and higher linear attenuation coefficients showed that the experimental data shows a better fit to Freundlich model (R2 = 0.9987) for Manihot esculenta, Langmuir model for Carica papaya and Moringa oleifera (R2 = 0.9931) (R2 = 0.9959). Kinetic studies were also executed for all the adsorbents and for Manihot esculenta data en suite well to pseudo-second order model (R2 = 0.9966), for Carica papaya (R2 = 0.9986) and for Moringa oleifera investigational data en suite well with Pseudo-first order (R2 = 0.9916) respectively.

Bacteria use quorum sensing as a way of inter and intra- species communication. Quorum sensing was found to be important for bacteria for various processes including establishing an infection through virulence and biofilm formation. This is mediated autoinducers, which are usually produced by one group of bacteria and recognized by another group through a response regulator protein. LuxR is a response regulator protein first discovered in Vibreo fischeri and it recognizes autoinducers produced by the same species of bacteria. E. coli also has a response regulator called SdiA which is a homolog of LuxR, originally found to be involved in transcription and cell division. SdiA was later reported to regulate quorum sensing by binding to autoinducers called Acyl Homoserine Lactones (AHLs). SdiA is also reported to be involved in enhancing the multidrug resistance and virulence in pathogenic E. coli. Though many studies elaborate the functional aspects of SdiA, sequence and structural level analysis of this protein is missing in the literature. The current work aims at the in silico analysis and targeting of SdiA with structural analogs of AHLs. 7 compounds were found to be promising molecules to inhibit quorum sensing in E. coli.

The world’s energy demand has increased drastically in the past and is likely to increase even more in the upcoming years. The fossil fuels are non-renewable energy, depleted at fast rate and this fact intensifies the need to look for alternative fuels to meet our day to day energy needs in all power sectors. The consumption rate of energy has increased tremendously and it necessitates increased supply of energy in all forms. The conventional energy resources like diesel, petroleum, gas and coal will soon be depleted. Hence there is a dire requirement to generate alternative sources of the fuel. Biodiesel is one of the best alternative and renewable fuel. It is oxygenate, Sulphur free and biodegradable. Oxygen content in biodiesel helps to improve the efficiency of the engine. Combustion chamber in compression ignition engine is one of the most important roles to enhance the fuel – air mixing rate (swirl) in short possible time. The turbulence is guided by the shape of the combustion chamber. The air swirl is created in combustion chamber, when the fuel air mixing rate increases. Hence the time duration of air fuel mixing rate decreases. The overall duration of the combustion process to shorten as swirl has leads to increases mechanical efficiency. In this work, in which biodiesel is prepared by transesterification process and engine performance is optimized by different parameters such as Piston shape, Load and Blend ratio and analyzed by Analysis of Variance.

An amplifier is an electronic circuit that improves the strength of the signal. Using an amplifier in an audio system is essential to improve the strength of the signal. Based on different applications and specifications different types of amplifiers are used. Generally in an audio system, the input signal is amplified to a minimum required power level and then the speaker is driven by it. Conventionally, the output stage of an audio amplifier uses Class-A or Class-AB operating in a linear transfer region. The power efficiency of the Class-D amplifier has a better output efficiency compared to Class-A and Class-AB amplifiers, and its distortion is lower than that of the Class-C amplifier. This is based on a known fact that the Class D amplifier has a switching action in which the transistors are either completely on or off. As a result, the amplification is achieved with no power dissipation. Hence, the size of the amplifier can be highly reduced and a smaller heat sink is required. This paper focuses on designing a Class-D power amplifier which is suitable for hearing aid devices to deliver 500mW output power and for the THD to be less than 3%. The circuit implementation is done using UMC high voltage 0.18μm technology. This amplifier consists of three stages such as the modulation stage, the driver stage, the bridge stage, and the demodulation stage. Unfortunately, the Class-D power amplifier has inherent non-linear distortion problems, which is more significant than conventional audio power amplifiers. In this thesis, negative feedback is employed to reduce THD. Without feedback, the THD is obtained as above 3%. By employing feedback, the THD was reduced by 1.96dB. This design result is discussed and through to realization; whereupon the effectiveness of each of the implementation is evaluated.

In recent times, social network services speedup the information proliferation among user groups, leaving the customary media such as newspaper, TV, discussion, web journals, and online interfaces far behind. Different messages are spread rapidly and broadly by re-tweeting in micro-blogs. Foreseeing re-tweet behavior is incredibly challenging because of different reasons. Existing forecasting models basically overlook sociological information and they don’t acquire complete benefit of these emerging factors, influencing the performance of anticipation. In addition, the poorness of re-tweet data also seriously upsets the performance of these approaches. In this article, we take Sina micro-blog for instance, intending to anticipate the probable quantity of re-tweets of an original tweet as per the time series dispersion of its top n re-tweets. So as to deal with the above issue, we present the idea of a tweet life-cycle, which is essentially calculated by three parameters called the reaction-time, content-significance, interim-time circulation, and afterward the given time series dispersion arch of its top n re-tweets is fitted by a two-stage function, in order to foresee the quantity of its re-tweets in specific time period. The stages in the function are partitioned by the life-cycle of the original tweet and various functions are utilized in the two stages. We have assessed our methodology on real-world data-set; moreover contrast our outcomes with baseline methods. Our examinations prove that the proposed methodology can precisely anticipate the quantity of future re-tweets for a particular tweet.

Driven by the rapid advancement in the field of Science and Technology, students regardless of areas and programmes are now exposed to a variety of immersive technologies. Therefore, it has become a challenge for educators in designing a meaningful learning experience. The use of such technologies has led to the emergence of new approaches in a learning experience, namely one that involves Virtual Reality (VR) and Augmented Reality (AR). Thus, understanding students’ readiness and expectancies is very important in leveraging the use of these technologies in teaching and learning. This study was conducted with the aim of addressing 2 objectives which are to identify the level of readiness of law students at the Faculty of Law, UKM in using VR in their learning; and, to identify the students’ expectancies when using VR in learning. Questionnaires were used to obtain data that were intended to measure the student’s readiness and expectancies. The findings showed that most of the students at the Faculty of Law have the technological readiness to use VR in their learning in law classrooms. However, some considerations need to be taken especially the availability of devices which does not ensure the existence of total willingness to accept something as new as using VR in a law class. As a conclusion, the findings of this study have brought into attention that VR technology can be used in law classrooms despite its discipline which has always been traditional (lectures and tutorials) and conventional (numerous readings, note-takings, and listening). However, the preparation of students’ affective domain is crucial especially in providing them with the strategies to learn with the help of VR technology.

When two or more signals of the satellite signals arrives through a GPS antenna with different tracks it leads to multipath phenomenon. The two main classifications of multipath phenomenon are specular and diffuse multipath. In the multipath pertaining to specular phenomenon the signals of GPS are reverberated through relatively sleek surfaces resulting in unsystematic errors within both pseudorange and carrier phase measurements. In contrast, diffuse phenomenal multipath is considered when the signal of GPS is incidental along a rough exterior where the reverberated signals are dispersed in various directions and generally they are unrelated in time period domain and it is noisy in activity. The stated unsystematic in-accurateness tin to be significant and leads to misconceptions of meters in the range in regard of pseudo range and for phase measurements at a range of a few centimeters . As the positioning mechanism needs to be be precised needs the straight path betwixt the satellites and a receiver, as the phenomenon of multipath doesn’t exist. The phenomenal multipath occurrences for the associated misconceptions in a GPS apparents eventually evidences for navigational misconceptions. Topical studies on GPS and its applications stimulate the necessitate for an improved multipath characterization techniques, to have an increased admiration for the spatial complexity and sequential of specific- position multipath environments.

When it comes to providing security to information systems, encryption emerges as an indispensable tool, as it has been used intensively in past few decades for securing stationary data as well as data in motion. Earlier, the security of an encryption algorithm lied in the manipulation of characters among a word or group of words, which is called the classical age of cryptography. This age ended when indigenous mathematical equations came into play and modern ciphers like DES and RSA were designed to mark the modern cryptographic era. This period witnessed two world wars and rise of machines instead of manual calculation for data secrecy. But, the time kept moving on and new advances in the information security field surfaced like Elliptical Curve Cryptography and Quantum Cryptography which added new dimensions to the secret world of confidential communication over unsecure channels. The latest addition in this count is the DNA cryptography which has combined the laws of biology with computing to form unbreakable ciphers at least theoretically. This paper introduces a new DNA cipher which is bound to provide more robust ways to safeguard vital data.

The project aims at designing an earthquake monitoring and warning system that is capable of detecting earthquakes as well as warning people to take necessary precautions. The designed system will not only try to save human lives, but will also store the data for later use by professionals working at this sector. India is a country with a high frequency of earthquakes. Since the country lies at the junction of three tectonic plates, the intensity of earthquakes felt in this region is moderate. But surprisingly, the number of deaths and financial loss in this region by earthquakes is not due to building crashes or being crushed under homes. Rather, major reasons of losses are due to indirect effects such as induction of fear, as well as fire induced from a cracked gas line or faulty electrical transmission line damaged by earthquakes. Hence, a low cost automatic microcontroller based system has been designed and implemented using low cost locally sourced electronic components, which senses earthquakes and gas leaks through accelerometer and gas sensor respectively. The microcontroller operates a relay and a motor that cuts off electricity and gas supplies respectively during the event of an earthquake, helping to prevent associated potential disasters.

The possibility of considering the seismodynamic problems of underground structures in quasistatic and static statements is substantiated theoretically. The methods of solving the equations of underground pipeline vibrations are given with account for elastic interactions in the pipe-soil system under seismic effect - seismodynamic and quasistatic methods. The conducted computational and experimental studies allow solving the problems of assessing the stress-strain state of pipelines under seismic loading, which is important for practical calculations.

Ministry of Human Resource Development (MHRD) is not only a source of inspiration for sectors such as Research and Development, Services, Agriculture and Entrepreneurship. They are also enhancing our competitiveness and relevance by proposing and executing different projects across the nation. The approach is in line with the vision 2030. As per 2018 Shanghai report of Times Higher Education (THE), only 40% academic and 10% of employer reputation is built as per the Global Ranking Standards. Indian Higher Educational warehouses with the help of National Institutional Ranking Framework (NIRF), Rashtriya Uchchatar Shiksha Abhiyan (RUSA) and University Grant Commission (UGC) are generating data which is of least relevance to end users. We propose peer to peer data curation model which shall be extended as per business need using a cloud technology. We have harnessed data related to the Higher Education Sector (HES) from Indian Institute of Sciences (IISc), RUSA, and MHRD, to understand Indian contribution towards global ranking standards in Higher Education Sector. The approach is in line with the Escuela Nueva Model and Open Architecture Information System (OAIS) as existing standards in traditional data curation process. It is supported by the patent in large-scale data curation.

Features of Human face is one of the unique biometrics used for identifying and recognizing humans. This makes face recognition system an integral component of numerous applications like identity verification of personnel at gates in many organizations, for controlled access of confidential resources, recognizing intruders by nationwide defense institutions, and such many more. Due to this the unavoidable need of face recognition system, practitioners and researchers are putting their continuous efforts to rectify and optimize the face recognition system for different perspectives in terms of accuracy, time, and storage. The techniques are also optimized for face captured at different degree of orientation, change of facial expression with time, lighting condition, with and without eyeglass and other props, but as isolated solutions. The main aim of the paper is to propose a system that can be installed at any door or gate which would operate based on integrated face recognition. The major contribution of this paper is twofold: i) An integrated face recognition solution optimized for recognizing multiple people faces captured at different orientations and even wearing eyeglasses of different shapes, sizes and materials ii) Smart Gate system being activated upon successful recognition of all faces captured simultaneously.
PYSCHOLOGICAL CONSEQUENCES OF VITAMIN D DEFICIENCY IN SENIOR
CITIZENS OF BANGALORE CITY
Authors: V. S. Jyothi Vybhavi
Published: January 2020

The older population is at a high risk of Vitamin-D deficiency due to decreased cutaneous synthesis and dietary intake of Vitamin-D. Results from
previous studies examining associations between serum 25- hydroxyvitamin D (25(OH)D) concentrations and depressive symptoms are
equivocal. Hence this study was undertaken in order to find the association between vitamin D and symptoms of depression, anxiety and stress in a
cross-sectional analysis of a population-based sample of elderly residing in Bangalore city. The objectives of this study are 1. To assess Serum
25(OH) Vitamin-D in the elderly. 2. To assess symptoms of depression, anxiety and stress in the elderly with different levels of Vitamin-D. This
study involved 80 healthy elderly subjects with consideration of inclusion and exclusion criteria. Written informed consent was taken. For each
subject, fasting blood sample of 4ml was collected for Serum 25(OH) Vitamin-D assessment. Anthropometric measurements were taken. 24-hour
dietary recall, General History Questionnaire and Mental health symptoms were assessed using the 21-item Depression Anxiety Stress Scales
(DASS-21). Associations between serum 25(OH)D concentrations and total DASS-21 scores and subscale scores of depression, anxiety and stress
were explored using negative binomial regression, adjusting for age, race, BMI and physical activity. The comparison of Serum Vitamin-D levels
and DASS-21 components showed that the mean scores for Depression, anxiety and Stress were significantly higher in the Vitamin-D deficient
participants, indicating that the Vitamin-D deficient participants had worst Psychological consequences. It can be concluded that a significant
correlation was found between Serum Vitamin-D deficiency and poor psychological health. Based on the results of this study, psychological health
for elderly can be improved by providing regular examinations and checking their Serum Vitamin-D levels and supplementing Vitamin-D to the
elderly to enhance their quality of Life.
PERFORMANCE OF PROGNOSTIC SCORES IN AKI POPULATION IN ICU
Authors: das Jasmin
Published: January 2020

Acute kidney injury in hospitalized patients is associated with high mortality rates and increased length of hospital stay. Prognostication of patients
with AKI is of immense value in making decisions regarding the optimal type and intensity of treatment, patient selection, and clinical discussions
on prognosis and in assessment of the quality of an ICU. Prognostic scores are comprised of relevant clinical and laboratory variables of patients
associated to the clinical endpoint. There are limited studies that have evaluated which prognostic score may be used in patients with AKI. Studies
have shown that APACHE II underestimates hospital mortality whereas AKI specific Liano score has better statistical correlation with mortality.
Materials and methods: All patients admitted to the ICU fulfilling the inclusion criteria during the study period were recruited and evaluated for
AKI by both RIFLE and AKI criteria. Prognostic scores, APACHE II and Liano were used in predicting hospital mortality. Assessment of score
performance was made through analysis of the discrimination and calibration using area under a receiver operating characteristic curve (AUROC)
and Hosmer and Lemeshow goodness of fit test.
Results: Mean APACHE II score was higher in AKI subjects compared to non AKI and was statistically significant and it increased with the
severity of AKI. The AUROC for APACHE II score was 0.739 and 0.706 for AKIN and RIFLE respectively and signifies APACHE II score
increases with AKI. An AUROC curve of prognostic scores for predicting mortality was 0.677 and 0.639 for Liano and APACHE II respectively
and on comparison showed insignificant p value (0.6331). Assessment of calibration showed that the calibration was good for specific score.
Conclusion:Assessment of performance of both the prognostic scores APACHE II and Liano had poor discrimination but calibration was good for
Liano model
NEEDLE-STICK AND SHARP INJURIES (NSIS) AMONG HEALTH CARE WORKERS:
A CROSS SECTIONAL STUDY IN A TERTIARY HEALTH CARE INSTITUTION OF
KOLKATA, INDIA
Authors: Das Sukesh
Published: January 2020

Background: NSI is an important but preventable occupational hazard among Health care workers (HCWs) all over the world.
Objective:To assess prevalence of NSIs and related knowledge and practices among HCWs of a tertiary health care institution.
Methods: It was an institution based, cross sectional study done among junior doctors (interns and house staffs) and nurses in a tertiary health care
institution of Kolkata. Complete enumeration was done and sample size was 215. Aself-administered questionnaire was used to collect data.
Results: The prevalence of NSIs was 22.3%, more among junior doctors compared to nurses (28.3% vs. 11.7%), majority experiencing 1-3
incidents in last 3 months. Recapping of needle was the most common activity leading to NSIs (56.3%). Only 14.6% reported their NSIs to their
authority. 64.2% of the study subjects were vaccinated against Hepatitis B. The study subjects had fair knowledge about the diseases transmitted by
NSIs, but their practice on post exposure prophylaxis (PEP) was poor. Heavy workload, fatigue, lack of protective measures and inadequate
training contributed to NSIs, as they reported.
Conclusion: Greater awareness and willingness to adhere to the designed protocols for sharps management among HCWs are urgently needed to
prevent this problem.
Course notes on finite games and rational choice
Authors: Bruni Riccardo
Published: January 2020

This book collects notes that were prepared for a university course taught in the Spring of 2018, and delivered to an audience of students enrolled in the Master course in Logic, philosophy and history of science of the University of Florence. The goal of the course was to introduce students to some basic concepts from the area of research generally known as decision theory. This is done by focussing on the concept of ‘rational choice’, which is analyzed, methodologically speaking, by the means of the theory of games. To minimize prerequisites it was decided to restrict the attention to the theory of finite games in particular. The topics treated are vary, and belongs to both the theory of games ‘in normal form’ as well as that of games ‘in extensive form’, as they are usually referred to. The classical issues in both fields, such as the theory of ‘equilibria’ and the study of properties such as determinacy, are carefully discussed to make them clear to beginners and are addressed from a novel perspective which makes use of formal methods that are typical of researches connected with the study of logic.
