Tabernaemontana divaricata (L) R. Br. (Apocynaceae) commonly known as Tagar in Bengali. It is a garden plant in tropical countries and found throughout the Indian subcontinent. The present investigation assessed the scavenging potential by 1, 1-diphenyl-2-picryl-hydrazyl (DPPH) assay. All of the extracts exhibited potent in vitro free radical scavenging activity that increased with extract concentrations. The methanol extract was found to be the most potent in this regard, followed by the benzene and ethyl acetate extracts. Therefore, the present study confirms marked in vitro free radical scavenging activity Tabernaemontana divaricata leaves.

Urinary tract infection (UTI) is a term applied to a variety of clinical conditions ranging from asymptomatic presence of bacteria in the urine to severe infection of the kidney with resultant sepsis. UTI is defined also as the growth of a known bacterial pathogen more than 10000 cfu/ml in association with a positive dipstick or urinalysis. Urinary tract infections (UTIs) are a serious health problem affecting millions of people each year. Infections of the urinary tract are the second most common type of infection in the body. These are one of the most common bacterial infections affecting humans throughout their life span. Most of urinary tract infections are caused by gram-negative bacteria like Escherichia coli, Klebsiella sp., Proteus mirabilis, Pseudomonas aeruginosa, Acinetobacter and Serratia. 90% of UTI cases are caused by gram-negative bacteria while only 10% of the cases are caused by gram-positive bacteria. Bacterial pathogens have evolved numerous defense mechanisms against antimicrobial agents; hence resistance to old and newly produced drugs is on the rise. The phenomenon of antibiotic resistance exhibited by the pathogenic microorganisms has led to the need for screening of several medicinal plants for their potential antimicrobial activity. The present study was conducted to identify the uropathogens based on morphological and biochemical characteristics and to study the antimicrobial effect of drugs, medicinal plant extracts and essential oils against uropathogens.

A very well known ancient fruit whose therapeutic qualities have rebounded and echoed throughout the millennia named as Punica granatum (belongs to family Punicaceae) also commonly known as Pomegranate, Anar or Dalim in North India. Plant based formulations have been used since ancient times and playing role as a remedial agent against various human and animal diseases. Therefore, in the systems of Allopathic, Ayurvedic, Homeopathic and Unani systems, much energy has been devoted to the treatment of disease and enhancement of physical and mental health. The interest in traditional medicines has increased in various parts of world. Punicalagin is chemically named as 2, 3-(S)-hexahydroxydiphenoyl-4, 6-(S,S)-gallagyl-D-glucose and belongs to a category of hydrolysable tannin. In this research, the main aim is to formulate the vesicular formulation of Punicalagin which was extracted, isolated and purified from peels of Punica granatum. Thus, to protect its hydrolysis, it is formulated into a nanocarrier system known as niosomes which is based on the preparation of niosomes by using a non-ionic surfactant in varying amounts and keeping the amount of cholesterol constant. The niosomal formulations were evaluated on the basis of evaluation parameters and thus optimized. The best optimized niosome formulation was then formulated as 1% w/w hydrogel and evaluated on the basis of parameters like homogeneity, rheological behaviour of hydrogel, spreadibility and gel strength, consistency, skin retention studies as well as in vitro and ex vivo drug release study. Comparative drug permeation study in vitro, ex vivo and skin retention study of niosomal gel as well as conventional gel concluded that amount of drug permeated and retained in skin from niosomal gel was much more as compared to conventional gel. The analysis of release pattern by niosomal and conventional gel was done by applying kinetic models to them and concluded that both formulations followed zero order kinetics.

Nigeria is classified as a mixed economy emerging market, and has already reached middle income status according to the World Bank, with its abundant supply of natural resource, well developed financial, legal, communications, transport sectors and stock exchange which is the second largest in Africa. The main purpose of this research is to build a model that can capture the best variables that predict the Gross Domestic Product (GDP) of Nigeria. Correlation matrix was used to know the degree of relationship that exists between the pairs of predictors of GDP. The principal component analysis was employed to reduce the multidimensional data. Scree plot was used to determine the spread of the trend of the components and bi plot was used to determine the degree of closeness of Agriculture, oil Export, External Reserves, Exchange Rate, Transportation, Education, and Communication. There is a strong relationship between pairs of Agriculture, oil Export, External Reserves, Exchange Rate, Transportation, Education, and Communication. The proportion of variance accounted for by the first component is 92%. This implied that only component 1 is sufficient to explain GDP. The Scree plot showed that the best component is component 1. The bi plot showed that Agriculture, oil Export, External.Reserves, Exchange.Rate, Transportation, Education, and Communication are closely related and stand as good predictors of GDP.

A carbon based (Graphene) working electrode containing enzyme alkaline phosphatase, cellulose acetate and Poly Vinyl Pyrolidone (PVP), Ferrocene, Horseradish peroxidise and aq. KOH was specially designed and fabricated. It is then combined with Ag/AgCl reference and a platinum electrode to form a three electrode based amperometric biosensor for the electrochemical detection of Enterobacter aerogenes as biological warfare agent (BWA) in the presence and absence of Fe3O4 nanoparticles. Fe3O4 nanoparticles were synthesized by sol-gel technique and were characterized by UV-visible, FTIR, TEM and XRD techniques. Change in current response and OCP values helps in the detection of BWA in presence and absence of Fe3O4 nanoparticles. Effects of temperature, stirring and Fe3O4 nanoparticles on the BWA have also been investigated.

This study examined the relationships between strategic business model, operational plans and big picture and strategic planning process among Libyan students in Malaysia. Data was collected from 204 respondents using structured questionnaire from the selected universities in Malaysia. The descriptive analysis revealed that, majority of the respondents were male who are mostly working in the tertiary institutions in Libya. Pearson correlation analysis using SEM have shown a significant positive and high relationship between strategic business model, operational plans and big picture and strategic planning process which means, higher strategic planning process is associated with these three concepts. In line with this finding the authors concluded that, strategic planning based on theory of Pfeiffer is applicable to Libyan universities due to significant and positive relationships between the concepts in Pfeiffer’s theory and strategic planning. Thus, the authors recommends that universities, particularly in Libyan should adopt the current approach of strategic planning in order to achieve the set objectives of their universities. Moreover, if this approach is implemented in the universities by the management, it will enhance in managing information and monitoring academic development.

Visual cryptography is special type of technique for encipher the confidential visual information (e.g. printed text, handwritten notes, and picture) in such a way, that decipher can be performed by human visual system (HVS) without any complex process, providing high security. In this paper a simple but robust visual cryptography scheme is proposed. In this scheme the secret is encrypted using symmetric key encryption algorithm, and then this encrypted data will be hidden into an image file, divided into parts called shares and then they are distributed to the participants. Thus accomplishing both data encoding and hiding. Only piling of shares does not revile the secret until shares are stacked together in a particular fashion and provided with the key. It can be used to hide the original secret information from an intruder or an unwanted user. The shares are very safe because separately they reveal nothing about the secret image. The algorithm proposed by this scheme reduces a considerable time for encryption and decryption in a much easier way and ensures the lossless transmissions of images. The proposed encryption algorithm in this study has been tested on some images and showed good results.
