Nursesâ Knowledge and Attitudes Regarding Pain in Emergency Departments: A Comparative Study
Background Effective pain management needs a strong base of pain-related knowledge and an optimal attitude toward pain, which could have a critical impact during treatment course. Aims To investigate emergency nursesâ knowledge and attitudes regarding pain and to compare pain-related knowledge and pain-related attitudes among emergency nurses working in the government and private hospitals. Design and Method A descriptive cross-sectional design was used. A total number of 175 nurses (84 from private hospitals, 91 from governmental hospitals) recruited through a convenient sampling method. Knowledge and Attitudes Survey Regarding Pain was used to collect data. The data were collected in 2017. Results It was found that the mean scores of Knowledge and Attitudes Survey Regarding Pain was 16.64 (SD= 4.94). Results revealed that nurses working in private hospitals have higher scores on Knowledge and Attitudes Survey Regarding Pain (M=17.59, SD= 5.6) than nurses working in governmental hospitals (M=15.75, SD= 4.08) (p-value <0.05). There was a significant difference among nursesâ scores on Knowledge and Attitudes Survey Regarding Pain which is attributed to nursesâ age and their educational level (p-value <0.05). Finding and Conclusion Nurses working in emergency departments have a knowledge and attitudes deficits regarding pain management. In-service educational programs about pain management are recommended for all nurses in every health care setting.

Microcredit, Technology Adoption and Economic Development of Rural Household
The main objective of this study is to investigate either Amanah Ikhtiar Malaysia (AIM) microcredit has led to the technology adoption and increase of rural household economy, particularly in household monthly income among its participants. This study was conducted in Melaka based on a sample of 200 participants. The findings of the study show that the AIM microcredit had a significant impact on technology adoption and increased the participant household monthly income in Melaka. The findings suggest that AIM microcredit is still relevant and plays an important role in increasing rural household monthly income, inculcate entrepreneurship among women and reduced poverty. Therefore, the Malaysian government should enact the relevant policies and give supports to enhance the effectiveness and outreach of microcredit
COMPARATIVE STUDY ON RING, ROTOR AND AIR-JET SPUN YARN
Although ring spinning is the universal spinning system but main limitation of this system is its limited spindle speed which causes lower production rate. Now-a-days spinners are trying to finding out various alternative spinning systems among which only rotor and air-jet has established market value. So it is very important for spinners to find out a suitable one according to end use and others economic aspects. Ring, Rotor and Air-jet spinning systems provide yarn with different structures and properties. Each system has its advantages and limitations in terms of technical feasibility and economic viability. We have produced 20's Ne, 100% cotton yarn from the above systems and their properties are tested by UT5 and lea strength tester. The main object of the project is to study the yarn properties (Um%, CVm%, Imperfection, Hairiness etc) of ring, rotor and air-jet spun yarn and compare among them. We observed how yarn properties are changed with the change of process. We analyzed the various yarn properties by the graphical representation

Non-Vacuum Bianchi Types I and V in f(R) Gravity
In a recent paper \cite{1}, we have studied the vacuum solutions of Bianchi
types I and V spacetimes in the framework of metric f(R) gravity. Here we
extend this work to perfect fluid solutions. For this purpose, we take stiff
matter to find energy density and pressure of the universe. In particular, we
find two exact solutions in each case which correspond to two models of the
universe. The first solution gives a singular model while the second solution
provides a non-singular model. The physical behavior of these models has been
discussed using some physical quantities. Also, the function of the Ricci
scalar is evaluated.Comment: 15 pages, accepted for publication in Gen. Realtiv. Gravi
MIP-based protein profiling: A method for interspecies discrimination
Due to recent public concern and interest in the authenticity and origin of meat, for example, the 2013 âhorsemeat scandalâ in the human food chain, novel sensor strategies for the discrimination between protein species are highly sought after. In this work, molecularly imprinted polymers (MIPs) are utilised for protein discrimination using electrochemical sensor and spectrophotometric techniques. MIP selectivity between two proteins of similar molecular weight (haemoglobin and serum albumin) were compared across three different species, namely pork, beef and human. Bulk MIPs resulted in Kd and Bmax values of 184±23 ”M, and 582 ”mol g-1 for BHb, 246.3±26 ”M, and 673 ”mol g-1 for HHb; 276±31 ”M, and 467 ”mol g-1 for PHb. With the aid of chemometrics, i.e. multivariate analysis and pattern recognition, distinctive protein profiles have been achieved for species discrimination in both spectrophotometric and electrochemical analysis experiments. MIP suitability and selectivity within complex matrices was also assessed using urine, human plasma and human serum. Pattern recognition MIP-based protein profiling demonstrated positive outputs yielding either a âbovineâ or ânot-bovineâ outcome (p = 0.0005) for biological samples spiked with/without bovine using respective bovine haemoglobin MIPs
Solvable K-essence Cosmologies and Modified Chaplygin Gas Unified Models of Dark Energy and Dark Matter
This paper is devoted to the investigation of modified Chaplygin gas model in
the context of solvable k-essence cosmologies. For this purpose, we construct
equations of state parameter of this model for some particular values of the
parameter . The graphical behavior of these equations are also discussed by
using power law form of potential. The relationship between k-essence and
modified Chaplygin gas model shows viable results in the dark energy scenario.
We conclude that the universe behaves as a cosmological constant, quintessence
phase or phantom phase depending upon .Comment: 14 pages, 6 figure
Newtonian and Post Newtonian Expansionfree Fluid Evolution in f(R) Gravity
We consider a collapsing sphere and discuss its evolution under the vanishing
expansion scalar in the framework of gravity. The fluid is assumed to be
locally anisotropic which evolves adiabatically. To study the dynamics of the
collapsing fluid, Newtonian and post Newtonian regimes are taken into account.
The field equations are investigated for a well-known model of the form
admitting Schwarzschild solution. The perturbation scheme is
used on the dynamical equations to explore the instability conditions of
expansionfree fluid evolution. We conclude that instability conditions depend
upon pressure anisotropy, energy density and some constraints arising from this
theory.Comment: 20 pages, accepted for publication in Astrophys. Space Sc
Non-vacuum Solutions of Bianchi Type VI_0 Universe in f(R) Gravity
In this paper, we solve the field equations in metric f(R) gravity for
Bianchi type VI_0 spacetime and discuss evolution of the expanding universe. We
find two types of non-vacuum solutions by taking isotropic and anisotropic
fluids as the source of matter and dark energy. The physical behavior of these
solutions is analyzed and compared in the future evolution with the help of
some physical and geometrical parameters. It is concluded that in the presence
of isotropic fluid, the model has singularity at and represents
continuously expanding shearing universe currently entering into phantom phase.
In anisotropic fluid, the model has no initial singularity and exhibits the
uniform accelerating expansion. However, the spacetime does not achieve
isotropy as in both of these solutions.Comment: 20 pages, 5 figures, accepted for publication in Astrophys. Space Sc
Highly selective BSA imprinted polyacrylamide hydrogels facilitated by a metal-coding MIP approach
We report the fabrication of metal-coded molecularly imprinted polymers (MIPs) using hydrogel-based protein imprinting techniques. A Co(II) complex was prepared using (E)-2-((2 hydrazide-(4-vinylbenzyl) hydrazono)methyl)phenol; along with iron(III) chloroprotoporphyrin (Hemin), vinylferrocene (VFc), zinc (II) protoporphyrin (ZnPP) and protoporphyrin (PP), these complexes were introduced into the MIPs as co-monomers for metal-coding of non-metalloprotein imprints. Results indicate a 66% enhancement for bovine serum albumin (BSA) protein binding capacities (Q, mg/g) via metal-ion/ligand exchange properties within the metal-coded MIPs. Specifically, Co(II)-complex-based MIPs exhibited 92 ± 1% specific binding with Q values of 5.7 ± 0.45 mg BSA/g polymer and imprinting factors (IF) of 14.8 ± 1.9 (MIP/non-imprinted (NIP) control). The selectivity of our Co(II)-coded BSA MIPs were also tested using bovine haemoglobin (BHb), lysozyme (Lyz), and trypsin (Tryp). By evaluating imprinting factors (K), each of the latter proteins was found to have lower affinities in comparison to cognate BSA template. The hydrogels were further characterised by thermal analysis and differential scanning calorimetry (DSC) to assess optimum polymer composition
