Variation of Important Non-Dimensional Numbers During Bubble Growth at Nucleation Site in Microchannels

This paper was presented at the 4th Micro and Nano Flows Conference (MNF2014), which was held at University College, London, UK. The conference was organised by Brunel University and supported by the Italian Union of Thermofluiddynamics, IPEM, the Process Intensification Network, the Institution of Mechanical Engineers, the Heat Transfer Society, HEXAG - the Heat Exchange Action Group, and the Energy Institute, ASME Press, LCN London Centre for Nanotechnology, UCL University College London, UCL Engineering, the International NanoScience Community, www.nanopaprika.eu.Two phase flow initiates at Onset of Nucleate Boiling, where the first bubble emerges in the downstream flow direction. Bubble nucleation and growth in microchannel heat sinks is very conspicuous phase as the growing bubble can completely block the flow cross-section area at high heat flux. Hence, microchannels are more susceptible to flow boiling instability. In this paper effort has been put to study the bubble dynamics during bubble growth at nucleation site for microchannel in terms of non-dimensional energy ratio numbers and their variation from bubble inception until departure. New non dimensional energy ratio is also proposed, which can be useful to differentiate inertia controlled and thermal diffusion controlled region during bubble growth at nucleation site

Preliminary phytochemistry and antimicrobial activity of bark of Bauhinia racemosa Lamk.

The bark of Bauhinia racemosa are reported to have great medicinal value. Phytochemical screening of the plant bark reveals the presence of carbohydrates, alkaloids, steroids and tannins. the methanol, ethanol, aqueous, acetone and petroleum ether extracts of bark of B. racemosa Lamk. prepared and antimicrobial activity were studied by agar well diffusion method against enteric bacterial pathogens such as E. coli, S. aureus, B. subtilis, P. aeruginosa and fungi A. niger and C.albicans. The methanol extracts had wide range of antimicrobial activity against enteric microbes than ethanol extracts, where as ethanol extract were slightly higher antibacterial activity than aqueous extract. Antimicrobial activity of various extracts of bark of B. racemosa was carried in attempt to develop a new pharmaceutical drug from natural origin for prevention of enteric infection

Determination of ash values of some medicinal plants of genus sesbania of marathwada region in maharashtra

The seasonal variation of total ash, water soluble ash and water insoluble ash have been investigated leaves , wood and bark of Sesbania grandiflora, Sesbania bispinosa and Sesbania cannabina, which are medicinally important. Comparative account of total ash, water soluble ash and water insoluble ash content of bark of Sesbania grandiflora showed high level of total ash (range  11.80 to 12.10 %) and low level of total ash of leaves of Sesbania cannabina ( range 5.05 to 5.35 % ) .The water soluble ash  showed higher level of wood of Sesbania grandiflora (range 4.30 to 4.80 % ) and lower in leaves of Sesbania cannabina (range 1.5 to 2.05 %),Comparative account of water insoluble ash of bark of Sesbania grandiflora showed higher (range 7.20 to 7.35 % ) and lower in the leaves of Sesbania bispinosa (range 2.9 to 3.1 % ).

Effect of different factors on in vitro growth and shoot proliferation of guava (Psidium guajava L.) cv. Allahabad Safeda

In the present experiment an attempt has been made to optimize the effect of different medium, levels of sucrose, pH, adenine sulphate and light intensity for culture establishment and shoot proliferation in guava using nodal segment explants. Culture establishment was greatly influenced by media types. Maximum establishment ofexplants (74.57%) was recorded on MS medium supplemented with 2.0 mg/l BAP + 0.2 mg/l IBA. In proliferation study, the maximum shoot proliferation was observed in MS + 1 mg/l BAP + 0.25 mg/l GA3. Sucrose 3% was found to be more favorable for maximum proliferation and growth of shoots moreover, it was reduced gradually as increased or decreased levels of sucrose from 30 g/l. among the various pH levels tested, pH 5.5 recorded maximum number of shoots (8.08) and maximum length of shoots (3.75 cm).In proliferation medium the length of shoot, numbers of shoots and growth rate were increased as increased the adenine sulphate level in the medium. Maximum proliferation was observed on 160 mg/l adenine sulphate in the medium. High light intensity 3000 lux was found to be most suitable for proper growth of regenerated shoots. Low light intensity (1000 lux) resulted in stunted growth. All the above factors significantly influenced shoot multiplication and growth. Thus, optimization of these factors showed significantly increased number of shoots and rapid multiplication. This could be useful for the in vitro production of cost effective healthy planting material of guav

Face Recognition in the Scrambled Domain Using MK-RDA

Facial look identity is a vital mission by means of human-interacting structures that goal to be aware of versions within the human’s emotional state. the principle challenge or the crucial part in surveillance society is the privacy-shielding era. because the rapid improvement in the internet international it turns into very essential to scramble the pics in the video or files for the duration of transmission. in this the biometric identity of photographs or faces from scrambled pictures plays a completely tough mission. Numbers of various technology are carried out to provide privateness for the duration of surveillance or during transmission of video however they're lack of essential traits, like reversibility or visible fine maintenance. in lots of scrambling methods the faces are covered by a few animation which may additionally or may not cover all faces or it receives hard to recover pics from this technique. Many guide method also are us used by which we will unscramble an photo but they are no longer powerful that a good deal. to overcome all this matters we proposed a novel approach- Many-Kernel Random Discriminate analysis (MK-RDA) to find out discriminative patterns from chaotic indicators. structures get better accuracy bring about best photos. To PIE and ORL datasets has getting above ninety% accuracy

ROLE OF NATURAL POLYMER IN SUSTAINED AND CONTROLLED RELEASE

Now a day there has been an important development in different dosage forms for existing and newly designed drugs and natural products, and synthetic as well as semi-synthetic excipients always need to be used for a variety of purposes. Gums and mucilages are widely used as natural materials for conventional and novel dosage forms. With the increasing interest in polymers of natural origin, the pharmaceutical world has compliance to use most of them in their formulations. Moreover, the tremendous orientation of Pharmaceutical world towards these naturally derived polymers has become a subject of increasing interest to discover, extract and purify such compounds from the reported origin. These polymers such as natural gums and mucilage are bio-compatible, cheap and easily available and are preferred to synthetic and semi synthetic excipients because of their lack of toxicity, low cost, availability, soothing action and non irritant nature. In the present review gums and mucilage’s, used as a excipients as well as carrier for sustained or controlled release

Loop-string-hadron formulation of an SU(3) gauge theory with dynamical quarks

Towards the goal of quantum computing for lattice quantum chromodynamics, we present a loop-string-hadron (LSH) framework in 1+1 dimensions for describing the dynamics of SU(3) gauge fields coupled to staggered fermions. This novel framework was previously developed for an SU(2) lattice gauge theory in $d\leq3$ spatial dimensions and its advantages for classical and quantum algorithms have thus far been demonstrated in $d=1$. The LSH approach uses gauge invariant degrees of freedoms such as loop segments, string ends, and on-site hadrons, it is free of all nonabelian gauge redundancy, and it is described by a Hamiltonian containing only local interactions. In this work, the SU(3) LSH framework is systematically derived from the reformulation of Hamiltonian lattice gauge theory in terms of irreducible Schwinger bosons, including the addition of staggered quarks. Furthermore, the superselection rules governing the LSH dynamics are identified directly from the form of the Hamiltonian. The SU(3) LSH Hamiltonian with open boundary conditions has been numerically confirmed to agree with the completely gauge-fixed Hamiltonian, which contains long-range interactions and does not generalize to either periodic boundary conditions or to $d>1$.Comment: 35 pages plus references, 5 figures. v2 includes typo corrections, trivial adjustments to text sectioning, and added reference
