Real Time Fluorescence in Situ Visualization of Latent Fingerprints Exceeding Level 3 Details Based on Aggregation Induced Emission.
Venue: Journal of the American Chemical Society
Year: 2020

A water soluble probe TPA 1OH with aggregation induced emission (AIE) activity is synthesized and used for expedient real time fluorescence in situ visualization of latent fingerprints (LFPs) TPA 1OH aqueous solution exhibits non fluorescence in pure water while strong fluorescence upon molecular aggregating induced by addition of non solvent. Fluorescence images of LFPs on variety of substrates, including rough surfaces such as walls, bricks, paper, are developed under 405 nm light, by im mersing in or spraying with TPA 1OH aqueous solution (30 mM) without any necessity of organic co solvent and post treatment steps. The probe is non cytotoxic at the concentration lower than 50 mM. The development process of LFPs is demonstrated by real time fluorescence in situ imaging. The exponential relationship between the relative fluorescence intensity and time is deduced from the fitting curve. The LFP images developed by TPA 1OH are evident and intact enough to allow that the Level 1 3 details are displayed and analyzed. Noteworthily, the Level 3 details of LFPs such as the fingerprint ridge width, the characteristics of the sweat pores are evidently visible under fluorescence microscopy. Even the nanoscopic details exceed ing Level 3 are visualized under super resolution microscopy with sub 50 nm optical resolution, which is the very first report on LFPs.
Perceived Risk on Online Store Image Towards Purchase Intention
Venue: Research in World Economy
Year: 2019

The main aim of this study is to identify purchase intention among Malaysian online consumer towards online store. A recent data provided by MCMC indicate that only 9.3 percent of Internet users in Malaysia admitted doing online purchasing despite huge number reflects Malaysian is heavy Internet users. This is due to the factors that the consumers are feared towards risk they may get during shopping online and this can affect their purchase intention activities. The finding identified that privacy risk and delivery risk are significant to purchase intention among online consumers in Malaysia. Meanwhile, financial risk, product performance risk, time risk, psychological risk, social risk and after sale risk are not significant to purchase intention. This indicated that Malaysian online consumers tend to care their personal information has been misused by third parties within their permission in order to prevent privacy risk in online shopping activities.
Innovation, agile project management and firm performance in a public sector dominated economy: Empirical evidence from high tech small and medium sized enterprises in China
Year: 2020

While agile project management has become increasingly important for high tech small and medium sized enterprises (SMEs) each firm's performance varies greatly due to their different degrees of innovation capability and internal and external environmental dynamics. Drawing on the resource based view as well as innovation capability and agile project management theories a comparative analysis was conducted of two high tech SMEs. The results were used to develop a theoretical model based on six hypotheses. Empirical research was carried out that included measurement of key variables, data collection and analysis, validity and reliability tests, regression analysis, and structural equation modeling, which confirmed five of the six initial hypotheses. The proposed model incorporates different innovation capability roles, considers project agility's enhancement of firm performance, and takes into account interactions between companies' innovation atmosphere and environmental dynamics in a public sector dominated economy (i.e. China) The results contribute to project agility management's theoretical development and refinement by presenting new findings on innovation and environmental dynamics. The results also provide guidelines for project agility practices in high tech SMEs in China, with the potential to improve these firms' performance. Implications and limitations are also discussed.
Biomimetic metal organic frameworks mediated hybrid multi enzyme mimic for tandem catalysis
Year: 2020

The combination of chemo and enzyme catalysis for multi step tandem reactions has presented great challenges for decades. Herein, glucose oxidase (GOx) and a metal organic framework MOF 545(Fe) which possessed peroxidase like activity, were combined to construct a mimic multi enzyme system for tandem catalysis. MOF 545(Fe) not only served as a support for the enzyme immobilization, but also contributed its catalytic activity to co operate with natural enzymes for the cascade reactions. Based on the prepared mimic multi enzyme system GOx@MOF 545(Fe) a colorimetric biosensor for glucose rapid detection was achieved with a low limit of detection (0.28 mM) and high specificity. Meanwhile, due to the protection of MOF 545(Fe) the immobilized enzyme exhibited excellent reusability and stability, e.g. long term stability, thermal stability and anti organic solvent stability. After being stored at room temperature for 7 days, the immobilized enzyme retained 92% of activity, while only 40% of activity of free enzyme was retained. And the immobilized enzyme maintained 71% of its initial activity after 5 cycles. This strategy of combining MOF mimics and natural enzymes for tandem catalysis may provide a novel and facile approach to design a highly efficient, stable, functional chemo enzyme composites catalyst, which holds great promise for applications in biosensing, biopharmaceutical and industrial catalysis.

Green marketing consumer attitude towards eco friendly fast moving household care and personal care products
Year: 2015

It is reported that, to a great extend, environmental degradation has been brought about by the over consumption activities of private households. India is no exception to this rule. With the growth of Indian economy, the Indian consumer has higher disposable income than before. With the ever increasing penetration of internet and social media, the purchasing behaviour of Indian consumers has changed dramatically. The spread of education and thus awareness has made Indian consumer pay attention towards deteriorating environment. However, the consumers" indications of positive attitude towards environmental issues do not necessarily lead to actual environmentally friendly purchasing behaviour. The primary objective of this study is to determine the attitude and perception of the Indian consumers for eco friendly fast moving household and personal care products in terms of product, price, place, and promotion. The study specifically focuses on fast moving consumer goods because they have a quick turnover, are of relatively low cost and used almost daily by individuals. The study is conducted in urban Faridabad, a National Capital Region city, with demographic profile of people as independent variable and targeting people who have achieved education at least up to higher secondary level.
Polyphasic characterization of bacteria obtained from upland rice cultivated in Cerrado soil
Venue: Brazilian journal of microbiology [publication of the Brazilian Society for Microbiology]
Year: 2018

This work aimed to characterize 20 isolates obtained from upland rice plants, based on phenotypic (morphology, enzymatic activity, inorganic phosphate solubilization, carbon source use, antagonism) genotypic assays (16S rRNA sequencing) and plant growth promotion. Results showed a great morphological, metabolic and genetic variability among bacterial isolates. All isolates showed positive activity for catalase and protease enzymes and, 90% of the isolates showed positive activity for amylase, catalase and, nitrogenase. All isolates were able to metabolize sucrose and malic acid in contrast with mannitol, which was metabolized only by one isolate. For the other carbon sources, we observed a great variability in its use by the isolates. Most isolates showed antibiosis against Rhizoctonia solani (75% and Sclerotinia sclerotiorum (55% and, 50% of them showed antibiosis against both pathogens. Six isolates showed simultaneous ability of antibiosis, inorganic phosphate solubilization and protease activity. Based on phylogenetic analysis of the 16S rRNA gene all the isolates belong to Bacillus genus. Under greenhouse conditions, two isolates (S4 and S22) improved to about 24% 25% 30% and 31% the Total N, leaf area, shoot dry weight and root dry weight, respectively, of rice plants, indicating that they should be tested for this ability under field conditions.
Discussion on Lean Marketing Strategies
Year: 2006

For enterprises,no customer means no profit.Based on such cognition,many enterprises aim at the mode or pursuing the increase in sales and the market size,which leads to the increase in sales while the profit is squeezed.The lean marketing does not mean such a marketing mode which pursues a short time sales increase and it is based on promoting the intellectual capital value,forming the intensified mode of pursing market share,the quality of market share and the increase of the profit in the same pace in order to establish the extended strategic profit niche.
Evaluating the long term impact of live science demonstrations in an interactive science show
Year: 2017

Science shows are a popular format for communicating science that are used widely across the world, yet there is little literature about the long term impact they may have. This research investigated the short and long term impact of a specific science show called 'Music to your ears' which was written and performed throughout the UK for students aged 11 16 years on behalf of the Institute of Physics. The impact is measured using the immediate reaction to the show, the number (and type) of demonstrations that were recalled long term, and the application of any memories since seeing the show. Quantitative and qualitative data were gathered using questionnaires immediately after the show and from focus groups that were held two and a half years later. In addition, interviews with professional presenters were conducted to allow for triangulation of data. Five science demonstration categories were developed to describe the essence of a demonstration; curiosity (C) human (H) analogy (A) mechanics (M) and phenomena (P) These categories were then used as a framework to discover which had the biggest impact over a long period of time. It was found that even after two and a half years, almost 25% of demonstrations from the show could be recalled without prompting. When prompted with verbal and visual clues, the group tested could recall more than 50% of the demonstrations from the original show. In addition, around 9% of the demonstrations were recalled in an alternative context to the show, suggesting that some cognitive processing may be happening with the most memorable elements of the show.
Phosphate solubilization and chromium (VI) remediation potential of Klebsiella sp. strain CPSB4 isolated from the chromium contaminated agricultural soil.
Venue: Chemosphere
Year: 2018

In this study, an effort was made to identify an efficient phosphate solubilizing bacterial strain from chromium contaminated agricultural soils. Based on the formation of a solubilized halo around the colonies on Pikovskaya's agar amended with chromium (VI) 10 strains were initially screened out. Out of 10, strain CPSB4, which showed significantly high solubilization zone at different chromium concentrations, was selected for further study. The strain CPSB4 showed significant plant growth promotion traits with chromium (VI) stress under in vitro conditions in broth. The plant growth promotion activities of the strain decreased regularly, but were not completely lost with the increase in concentration of chromium up to 200 mg L 1. On subjected to FT IR analysis, the presence of the functional group, indicating the organic acid aiding in phosphate solubilization was identified. At an optimal temperature of 30 degC and pH 7.0, the strain showed around 93% chromium (VI) reduction under in vitro conditions in broth study. In soil condition, the maximum chromium (VI) reduction obtained was 95% under in vitro conditions. The strain CPSB4 was identified as Klebsiella sp. on the basis of morphological, biochemical and 16S rRNA gene sequencing. This study shows that the diverse role of the bacterial strain CPSB4 would be useful in the chromium contaminated soil as a good bioremediation and plant growth promoting agent as well.
The Bimodal Metallicity Distribution of the Cool Circumgalactic Medium at z 1
Year: 2013

We assess the metal content of the cool ~104?K) circumgalactic medium (CGM) about galaxies at z 1 using an H I selected sample of 28 Lyman limit systems (LLS; defined here as absorbers with 16.2 log N H I 18.5) observed in absorption against background QSOs by the Cosmic Origins Spectrograph on board the Hubble Space Telescope. The N H I selection avoids metallicity biases inherent in many previous studies of the low redshift CGM. We compare the column densities of weakly ionized metal species (e.g. O II, Si II, Mg II) to N H I in the strongest H I component of each absorber. We find that the metallicity distribution of the LLS (and hence the cool CGM) is bimodal with metal poor and metal rich branches peaking at [X/H] ?1.6 and ?0.3 (or about 2.5% and 50% solar metallicities) The cool CGM probed by these LLS is predominantly ionized. The metal rich branch of the population likely traces winds, recycled outflows, and tidally stripped gas; the metal poor branch has properties consistent with cold accretion streams thought to be a major source of fresh gas for star forming galaxies. Both branches have a nearly equal number of absorbers. Our results thus demonstrate there is a significant mass of previously undiscovered cold metal poor gas and confirm the presence of metal enriched gas in the CGM of z 1 galaxies.
The Economic Impact of Anticipated House Price Changes Evidence from Home Sales
Year: 2011

If realized house prices have the wealth effect and the collateral effect on the economy, anticipated house price changes should have similar economic effects. This article empirically analyzes the effects of single family home sales, which are shown to be able to predict house prices in the literature, on economic production, using 372 metropolitan statistic areas in the United States from the first quarter of 1981 to the second quarter of 2008 in a panel vector error correction model. Changes in home sales are found to Granger because the growth rate of per capita gross metropolitan product and the dynamic effects are visualized with impulse response functions. Supporting evidence for the economic impact of home sales is also found in contemporaneous regressions.
Identification of a new natural gastric lipase inhibitor from star anise.
Venue: Food function
Year: 2019

The identification and isolation of bioactive compounds are of great interest in the drug delivery field, despite being a difficult task. We describe here an innovative strategy for the identification of a new gastric lipase inhibitor from star anise for the treatment of obesity. After plant screening assays for gastric lipase inhibition, star anise was selected and investigated by bioactivity guided fractionation. MALDI TOF mass spectrometry and peptide mass fingerprinting allowed the detection of an inhibitor covalently bound to the catalytic serine of gastric lipase. A mass directed screening approach using UPLC HRMS and accurate mass determination searching identified the flavonoid myricitrin 5 methyl ether (M5ME) as a lipase inhibitor. The inhibitory activity was rationalized based on molecular docking, showing that M5ME is susceptible to nucleophilic attack by gastric lipase. Overall, our data suggest that M5ME may be considered as a potential candidate for future application as a gastric lipase inhibitor for the treatment of obesity.
Integrating Hydrological Modelling and Ecosystem Functioning for Environmental Flows in Climate Change Scenarios in the Zambezi River (Zambezi Region, Namibia)
Year: 2017

The Zambezi Chobe wetlands in Namibia are of great international importance for trans boundary water management because of their remarkable ecological characteristics and the variety and magnitude of the ecosystem services provided. The main objective of this study is to establish the hydro ecological baseline for the application of environmental flow regimes (EFR) The specific objectives are: (i) the assessment of environmental flow components (EFC) in the current near natural hydrological conditions; (ii) the generation of future scenarios for climatic and socioeconomic changes; (iii) the estimation of the area duration curves and estimated annual habitat during the inundation of the critical habitats for fisheries (mulapos) under the existing conditions and future scenarios; and (iv) to provide a framework for the future application of EFRs, based on hydrological and ecological processes. To make a sound analysis of the ecological implications, first we develop a conceptual framework of the linkages between the hydrological and biological processes concerning fish communities, because of the critical role of fisheries in the region. The EFCs in near natural hydrological conditions provide the basis for developing interim EFRs in the region, within the framework of an adaptive management of water resources. The future scenarios indicate a mitigation of the flow variability; and, in the worst case scenario, the reduction of the maximum flow and inundated area of the mulapos would result in a reduction of the estimated annual habitat of 22% This means a reduction in the spawning habitats for quiet water species, in the food resources for fry and juvenile fish and a consequent reduction in fish stocks. Furthermore, the habitat loss during low events is similar and greater under both scenarios, at ca. 35% Here we corroborate that the EFCs and their variability may become the building blocks of flow ecology models that lead to environmental flow recommendations, monitoring and research programmes and flow protection activities.
Black carbon absorption at the global scale is affected by particle scale diversity in composition
Venue: Nature communications
Year: 2016

Atmospheric black carbon (BC) exerts a strong, but uncertain, warming effect on the climate. BC that is coated with non absorbing material absorbs more strongly than the same amount of BC in an uncoated particle, but the magnitude of this absorption enhancement (Eabs) is not well constrained. Modelling studies and laboratory measurements have found stronger absorption enhancement than has been observed in the atmosphere. Here, using a particle resolved aerosol model to simulate diverse BC populations, we show that absorption is overestimated by as much as a factor of two if diversity is neglected and population averaged composition is assumed across all BC containing particles. If, instead, composition diversity is resolved, we find Eabs=1 1.5 at low relative humidity, consistent with ambient observations. This study offers not only an explanation for the discrepancy between modelled and observed absorption enhancement, but also demonstrates how particle scale simulations can be used to develop relationships for global scale models.
Untitled (Too real is this feeling of make believe)
Year: 2015

Tucker Pierce works to examine the constructed nature of identity through the act of modifying the surface of his body, the site of all identity expression, and through the strategic crossing of borders, both internally and externally. Using drag and his own body, he crosses the internal boundaries that govern identity expression and then the more physical border between the private and public sphere. He crosses this boundary by taking this modification of his external identity expression into the world at large. On a personal level, this project allows him to engage more completely with his own sense of self, and at a more public level it allows him to expose a crack in the system of gender, something society wants us to perceive as a strict and un malleable binary and that works to oppress individuals based on what are perceived as inflexible differences. Using the artist's body as an armature for the multiple originals that identity can take the form of, as well as the primary site of identity and identification, he explores the disjunction between his expected performance and the modifications of that expectation that he presents. By upsetting the social contracts that govern all identity expression, Untitled (Too real is this feeling of make believe) reveals the fluidity and self awareness that can be achieved when one stop taking themselves too seriously.
A Gender Approach to Militancy (Extremism) in Pakistan A Case Study of North Western Region
Venue: Pakistan Journal of Gender Studies
Year: 2019

The agenda of gender and security in the debate of international relations has much to achieve yet. The notion is based on normative differences of feminism and realism. The former is a flag bearer of feminist agenda of political studies and the latter is a leading International Relations paradigm. There have been many case studies and accounts in which women as victims of conflicts are studied and their plights are analyzed, however, the role of women as 'security agent' had hardly been previously touched. The gender inequality worsens the situation in Pakistani society as it promotes radical/extremist tendency which subsequently poses immense security challenges to the social fabric. Due to lack of research on this particular issue, the study has been opted for further exploration. Pakistan being at the forefront in the war against terror since its onset in 2001, has predominantly a military based security agenda. However, the country with 52% of female population, makes it an appropriate case study to understand security and gender. This paper pertains to some conflict hit areas of Pakistan where women role has been analyzed as security agent. This paper is an attempt to explore and analyses the theoretical and academic debate of gender and security with particular reference to North Western Pakistan.
Glutathione and Sulfur Amino Acids in Human Health and Disease
Year: 2009

The complex roles of glutathione and sulfur amino acids in human health Glutathione L glutamyl L cysteinylglycine, GSH) is a major antioxidant acting as a free radical scavenger that protects the cell from reactive oxygen species (ROS) Sulfur amino acids (SAAs) such as methionine and cysteine, play a critical role in the maintenance of health. GSH depletion as well as alterations of SAA metabolism are linked to a host of disease states including liver cirrhosis, various pulmonary diseases, myocardial ischemia and reperfusion injury, aging, Parkinson's disease, Alzheimer's disease, sepsis, and others. This book provides researchers with a comprehensive review of the biochemistry, absorption, metabolism, biological activities, disease prevention, and health promotion of glutathione and sulfur amino acids.
