High-resolution optical analyses of inositol 1,4,5-trisphosphate receptors and the Ca²⁺ puffs they evoke
… ([Ca²⁺]<sub>c</sub>), known as Ca²⁺ puffs, which arise from the coordinated opening of a few IP₃Rs within a cluster. IP₃R clusters that are immobilised near to the plasma membrane are preferentially licensed to respond to IP₃ with Ca²⁺ puffs. Ca²⁺ puffs can regulate local Ca²⁺ sensors …

An Experimental Study of Momentum-Driven Unsteady Jets
… focused on single ejection events (single puffs) where an instantaneous supply of momentum drives the source fluid downstream of a nozzle. This work focuses on dual puffs in which two volumes of fluid (dual puffs), separated by a time ∆p are ejected from a jet orifice into ambient. An …

High-resolution optical analyses of IP3-evoked Ca2+ signals
… report the opening of single IP3Rs, Ca2+ ‘puffs’ report the almost simultaneous opening of a few clustered IP3Rs, and as stimulus intensities increase further Ca2+ signals propagate regeneratively as Ca2+ waves. The aim of this study was to establish whether all three IP3R subtypes can …

ΜΕΛΕΤΗ ΤΩΝ ΠΟΛΥΤΑΙΝΙΚΩΝ ΧΡΩΜΟΣΩΜΑΤΩΝ ΤΩΝ ΚΥΤΤΑΡΩΝ ΤΩΝ ΣΙΑΛΟΓΟΝΩΝ ΑΔΕΝΩΝ ΤΗΣ DROSOPHILA AURARIA
… INFORMATION ON THE DEVELOPMENTAL PROFILES OF ITS PUFFS AND BRS. AUTORADIOGRAPHY HAS BEEN PERFORMED IN ORDER TO CONFIRM THE RNA SYNTHESIS OF THE BRS DURING DEVELOPMENT. INFORMATION IS PRESENTED ON THE EXISTENCE OF TANDEM INVERTED DUPLICATIONS INVOLVING THE BRS REGIONS AND OTHERS OF THE CHROMOSOMES, …

Flame Structure and Emissions of Strongly-Pulsed Turbulent Diffusion Flames with Swirl
… structure to range from isolated fully-modulated puffs to interacting puffs to steady flames. The swirl level is controlled by varying the ratio of the volumetric flow rate of the tangential air to that of the axial air. For strongly-pulsed flames, both with and without swirl, the flame geometry …

Sensory and Hypothalamic Control of Lordosis Behavior in Female Rodents
… of penile thrusts to the vaginal opening. Puffs of air directed to the lateral flank surface triggered lordosis in some estrogen-progesterone treated, ovariectomized female hamsters. This stimulation covered only a small area of the flank, and exerted very little pressure on deep …

Histone modification during the induction of tyrosine transaminase
… shortly after hormone administration. Since puffs are local and reversible alterations of the chromosome, formed at sites which are active in the synthesis of informational RNA, their formation shows a change in activity of particular gene loci in response to ecdysone.

Measurement and Analysis of Cigarette Smoke Exposure and Smoking Behavior Using Wearable Sensors
… the number of cigarettes, the number of puffs, duration of puff, or duration of cigarette smoking. None of the methods available to date can identify the post-puff information such as depth of inhalation, smoke holding duration, etc. This information is vital in understanding the detailed …

Dual regulation of inositol 1,4,5-trisphosphate receptors by inositol 1,4,5-trisphosphate and phosphatidylinositol 4,5-bisphosphate
… starting from brief, localised Ca<sup>2+</sup> puffs, and progressing to cell-wide global Ca<sup>2+</sup> waves. Tight control of the transition from local to global Ca<sup>2+</sup> signals is central to the downstream consequences of receptor activation. PI(4,5)P<sub>2</sub>, with its essential …

Fast photodiode diagnostic on Alcator C-Mod tokamak to study the plasma edge/SOL structure
… at a rate of 1 MHz. Two plasma-directed gas puffs are employed at the inboard and outboard plasma edges to enhance the emission at the desired toroidal locations. The absolutely calibrated views yield the required data for building radial and poloidal profiles of the intrinsic D, plasma …

Tomographic Reconstruction of 2-D Atmospheric Trace Gas Distributions from Active DOAS Measurements
… an indoor experiment simulating narrow emission puffs and 2-D model distributions above a street canyon, respectively. For the latter case it is demonstrated how model evaluation can be possible even with a relatively small number of light paths. Contrary to the reconstruction of peak …

Theoretical Studies of L-shell X-ray Line Polarization and M-shell X-ray Spectroscopic Emission from Highly Ionized Xenon Ions
… studied for lithography applications and Xe gas-puffs have proven to be efficient radiation sources. Consequently, a new M-shell Xe non-LTE model was constructed using atomic database calculations with the Flexible Atomic Code (FAC) and is presented in this dissertation. From this new model, …

Design and development of an automated metered dose inhaler (MDI) for asthmatic patient
… its percentage value. The display of available puffs of MDI canister and the battery indicator for the system are also included in the device. The automated actuation MDI was required a push button to press the MDI canister where this project utilised Arduino Nano as the microcontroller to …

The rise and dilution of buoyant jets and their behaviour in an internal wave field
… line or axisymmetric sources or of spherical puffs into a flowing, stratified ambient environment are uniquely specified using three parameters. These are: the non-dimensional size of the outlet port, the relative importance of the initial fluxes of momentum and buoyancy, and the number of …

Investigating casein-polymer interactions as a platform technology for cheese for Asian consumers
… and/or product development perspective. Cheese puffs (manufactured using microwave vacuum drying: MVD) produced from Cheddar curds with or without polysaccharide addition at dry salting were characterised. MVD was shown to be a promising technology to produce dried cheese snacks with minimal …

Phase transitions in fluids and biological systems
… lifetime and the splitting of turbulent puffs, and the growth rate of turbulent slugs, can all be explained by a coarse-grained, phenomenological model in the directed percolation universality class. To relate this critical phenomena approach closer to the fluid dynamics, I consider the …
