1 In December 1970, the World Bank asked National Hurricane Center, Miami, Fla., for services of a hurricane expert to evaluate deficiencies in Pakistan Cyclone Warning Service. This paper summarizes results two fact-finding trips East by Dr. Frank.

Communication induced checkpointing (CIC) allows processes in a distributed computation to take independent checkpoints and avoid the domino effect. This paper presents an analysis of CIC protocols based on prototype implementation validated simulations. Our result indicate that there is sufficient evidence suspect much conventional wisdom about these questionable.

Experimental studies on heat transfer and fluid flow of water in a vertical annulus, circulating through cold leg forming closed loop thermo-siphon, have been carried out this article. The annulus has radius ratio (outer to inner radius) 1.184 aspect (length annular gap) equal 352. experiments were conducted for constant fluxes 1, 2.5, 5, 7.5, 10, 12.5, 15 kW/m2. Transient behavior during the heat-up period system until steady-state condition is attained discussed. Variation coefficient...

The present study focuses on the advancement of a chloride ion potentiometric sensor that exhibits high selectivity. This employs novel molecule, namely N, N-Ethylene-bis-(Salicylideneaminato) zinc (II), in order to achieve accurate measurements pursuit maintaining clean environment. N′-Ethylenebis( salicylideneaminato) nickel (II) ionophore has been generated as well evaluated using analysis NMR, IR and C, H, N. Subsequently, membranes incorporating (I) were developed utilizing poly(vinyl...

In this research, we conduct a computational investigation into the mixed convection flow of copper/water nanofluids (NFs) within rectangular cavity, utilizing Lattice Boltzmann Method (LBM). The cavity is uniquely configured with five high-temperature obstructions (HOBs), and vary their dimensions positions to evaluate Nusselt numbers (Nu) across range Richardson (Ri). three walls excluding moveable top wall, are thermally insulated, while latter maintained at lower temperature. A constant...

Traditional agricultural techniques struggle to meet the requisite sustainability and resource efficiency requirements with growing demand for global food supply. High water usage, degradation of soil excessive energy usage are becoming pressing. This study seeks binary solutions these challenges potential improvement production methods aquaponics, or an integration aquaculture hydroponics. What is causing problem desire come up a more eco friendly technique accommodate increase in...

In the present work, twelve machine learning (ML) models are developed for assessment of monthly average diffuse solar radiation (DSR) with solitary input forecaster as clearness index. Two categories ML were demarcated (i.e. diffusion coefficient and fraction) six each group. The correctness was examined a function some frequently used statistical pointers. A comparision also done between well-recognised available from previous works. results show that perform very well in to literature....

N-Acylsydnone imines, anhydro-4-N-benzoylimino-2,3-diphenylthiazolium hydroxide, and anhydro-4-N-benzoylimino-2,3-diphenyl-1-methylimidazolium hydroxide undergo 1,3-dipolar cycloaddition with dimethyl acetylenedicarboxylate the formation of substituted pyrazoles, thiophen pyrrole, respectively.

Numerical and experimental analysis of natural convection subcooled boiling flow in a high aspect ratio narrow vertical annulus operating at atmospheric pressure is carried out. The computational model developed using RPI wall model. annular gap 3.5 mm 352. A new empirical relation for nucleation site density the present geometrical configuration implemented Fluent code with help user-defined function (UDF). results from numerical are then compared which show excellent agreement. superheat...

Experimental and numerical analyses have been carried out for single-phase natural convection thermally induced flow in an internally heated vertical annulus. The experiments are performed on in-house setup having annulus of aspect ratio 352 with the heat flux ranging from 2.5 kW/m2 to 15 kW/m2. Water is used as working fluid. simulations by a computational fluid dynamics (CFD) model developed using commercial software package Ansys Fluent. results present analysis then compared experimental...

Abstract A numerical inspection on natural convection inside a vertical annulus interior of which water based (Al 2 O 3 + MWCNT) (7:3) hybrid nanofluid has presently been carried out using CFD solver Ansys Fluent. Finite volume method (FVM) is used to perform the simulations at constant heat flux 3kW/m and various fraction (0-0.04) nanoparticle. The thermal conductivity viscosity computed by modified Maxwell model Batchelor respectively. paper explicit analysis effect nanoparticle...

Abstract The seed oil of Abutilon indicum (Malvaceae) contains three HBr‐reactive fatty acids. These are shown to be cis‐12,13‐epoxyoleic (vernolic) acid, 1.6% 9,10‐methylene‐octadec‐9‐enoic (sterculic) 0.9%; as well 8,9‐methylene‐heptadec‐8‐enoic (malvalic) 2.3%. Quantitative results obtained by combining informations about the HBr‐titration, preparative thin layer separation oxygenated and non‐oxygenated acids, gas liquid chromatographic analysis.
