Role of civil society institutions in promoting diversity and pluralism in Chitral District of Khyber Pakhtunkhwa, Pakistan

Pakistan is a country with a fast growing population of nearly 190 million people divided into a large number of ethnic, cultural, linguistic, political and religious groups. The basic ideology behind the creation of Pakistan was Islam and it was considered to be the unique force which could bind together the religiously, ethnically, linguistically, and culturally diverse society. An overwhelming majority of Pakistan’s population is Muslim with Sunni and Shia as the two major schools of thoughts but there are many other smaller sects within Muslim and non-Muslim population. Ethnically, Pakistani society is divided into major groups such as Punjabis, Sindhis, Pukhtuns, Balochis, Saraikis, Kashmiris, Hazaad, Shina and Baltis, and Chitralis etc. with numerous smaller ethnic groups

Effect of carboxymethyl cellulose-based coatings incorporated with Zataria multiflora Boiss. essential oil and grape seed extract on the shelf life of rainbow trout fillets

To prolong the shelf life of seafood products, lipid oxidation and growth of microorganisms should be retarded. The objective of the current study was evaluating the potential application of carboxymethyl cellulose (CMC) coatings incorporated with Zataria multiflora Boiss. essential oil (ZMEO) and grape seed extract (GSE) on chemical (thiobarbituric acid reactive substances (TBARS) and total volatile basic nitrogen (TVB-N)), microbial (total viable count, lactic acid bacteria and Pseudomonas spp.) and organoleptic attributes of rainbow trout fillets during refrigerated storage for twenty days. GCeMS analysis showed that ZMEO is rich in monoterpene phenols such as thymol and carvacrol. The following results were obtained after 20 days of storage: The minimum level of TVB-N was measured in the fillets coated with CMC + 2 v/v ZMEO + 0.5 v/v GSE. The minimum number of total viable bacteria, lactic acid bacteria and Pseudomonas spp. were determined in the fillets coated with CMC + 2 v/v ZMEO + 1 v/v GSE. The fillets coated with CMC + 1 v/v ZMEO + 1 v/v GSE showed the best organoleptic properties. Our results revealed that CMC-based coatings incorporated with ZMEO and GSE could improve chemical, microbial and sensorial characteristics of rainbow trout fillets during cold storage. © 2015 Elsevier Ltd

Dependence of chaotic behavior on optical properties and electrostatic effects in double beam torsional Casimir actuation

We investigate the influence of Casimir and electrostatic torques on double beam torsional microelectromechanical systems with materials covering a broad range of conductivities of more than three orders of magnitude. For the frictionless autonomous systems, bifurcation and phase space analysis shows that there is a significant difference between stable and unstable operating regimes for equal and unequal applied voltages on both sides of the double torsional system giving rise to heteroclinic and homoclinic orbits, respectively. For equal applied voltages, only the position of a symmetric unstable saddle equilibrium point is dependent on the material optical properties and electrostatic effects, while in any other case there are stable and unstable equilibrium points are dependent on both factors. For the periodically driven system, a Melnikov function approach is used to show the presence of chaotic motion rendering predictions of whether stiction or stable actuation will take place over long times impossible. Chaotic behavior introduces significant risk for stiction, and it is more prominent to occur for the more conductive systems that experience stronger Casimir forces and torques. Indeed, when unequal voltages are applied, the sensitive dependence of chaotic motion on electrostatics is more pronounced for the highest conductivity systems.Comment: 24 pages, 11 figure

Recurrences in an isolated quantum many-body system

Even though the evolution of an isolated quantum system is unitary, the complexity of interacting many-body systems prevents the observation of recurrences of quantum states for all but the smallest systems. For large systems one can not access the full complexity of the quantum states and the requirements to observe a recurrence in experiments reduces to being close to the initial state with respect to the employed observable. Selecting an observable connected to the collective excitations in one-dimensional superfluids, we demonstrate recurrences of coherence and long range order in an interacting quantum many-body system containing thousands of particles. This opens up a new window into the dynamics of large quantum systems even after they reached a transient thermal-like state.Comment: 5 pages, 4 figures + supplementary materials (9 pages, 6 figures

Change agents’ orientations to change

This study explores five field education officers’ (FEOs) understanding of their dual roles as educational reformers and community developers in the rural, mountainous district of Chitral, Pakistan. In particular, it examines their specific actions and methods (strategies) and their underlying assumptions and core values (orientations) of change. These FEOs work as change agents in schools and in the local communities where schools have been established by the Aga Khan Education Service, Pakistan (AKES,P). The study’s findings derive from empirical data collected through qualitative research methods, such as semi-structured interviews (individual and focus-group), non-participant observations, post-observation discussions, informal conversations and analysis of relevant documents. The findings capture three realms of the FEOs’ world: a) The FEOs’ role as external change agents; (b) their daily practices of change, and (c) their conceptual underpinnings of change. In the first realm, the study finds that the FEOs play a unique role, that of educational reformer and community developer, stimulating change in both schools and in local communities. These FEOs are authorized by AKESP’s district management; therefore, it is mandatory for AKESP schools and schools’ communities to accept their interventions. In the second realm, analysis of the FEOs’ specific actions and key methods for change reveals four distinct strategies the FEOs adopt for school change —Teacher-Centred, Moral Persuasion, Pragmatic, and Leadership— and three main strategies for community development —Participatory, Training, and Power-Laden. All seven strategies illuminate the FEOs’ understanding of change at the level of practice. In the third realm, this study explores the FEOs’ underlying assumptions, core values, and key concepts of change; it reconstructs three broad change orientations —Political, Technical, and Spiritual— into which each FEO’s theoretical understandings and conceptual frameworks of change are categorized. Examining the interrelatedness of the FEOs’ roles, strategies, and change orientations reveals that each FEO’s change orientation serves as a lens through which that FEO views and approaches change, defines his role, and shapes his strategies for change. Despite their distinct orientations, unique role, and particular strategies, all five FEOs operate within a common broader framework of socioeducational change or more, specifically, community-based school change

The effects of Lactobacilli from raw meat beef on E. coli O157: H7

Background and aims: Lactobacilli are widely distributed in the nature and are present almost everywhere. Because the bacteria are present in various food products, they are used for many years in foods. Studies show lactobacilli has antibacterial properties. The aim of this study was to isolate and identify the species of Lactobacillus from raw beef meat samples and evaluate their antibacterial properties. Methods: In this experimental study, 72 samples of raw beef meat were obtained from slaughterhouses of Sanandaj city. Isolates were evaluated using phenotypic methods (morphology, gram stain and catalase test). In order to identify more precisely, the fermentation of sugars test and molecular polymerase chain reaction (PCR) methods were used. Then, agar well diffusion and spot on plate methods were used to evaluate antibacterial properties of lactobacilli against E. coli O157: H7. Results: A total of 8 species Lactobacilli were isolated from raw beef meat and identified by chemical and molecular methods. The results showed that these 8 species of lactobacilli inhibited E. coli O157: H7 well. These results statistically was considered significant (P<0.05). Conclusion: The results of this study show that raw beef meat has different lactobacilli that can be used as a biological control in foods

Effect of Zataria multiflora Boiss Essential Oil and Grape Seed Extract on the Shelf Life of Raw Buffalo Patty and Fate of Inoculated Listeria monocytogenes

The present study was conducted to investigate the effect of Zataria multiflora Boiss essential oil (ZEO) and grape seed extract (GSE) on microbial and chemical changes in raw buffalo patty at a temperature of 8C. First, chemical composition and minimum inhibitory concentration of oil against Listeria monocytogenes were identified. Then, ZEO and GSE were added in raw buffalo patties and analyzed for spoilage microorganism count, lipid oxidation, pH, sensory attributes and inoculated L.monocytogenes survival at 8C for 9 days. Results revealed that samples containing 0.1 ZEO+0.2 GSE showed significant decrease in the growth of all tested microbial groups as well as the most decrease in the level of lipid oxidation at the end of storage period. Control and samples with 0.1 ZEO were the most preferred samples by sensory panelist, indicating that ZEO and GSE can be practically applied in food systems especially in meat in order to extend the shelf life. Practical Applications: Buffalo meat is highly prone to microbial and chemical spoilage as they are rich in essential nutrients and putrefying in nature. The adverse effects of various chemical preservatives caused to attract the consumer's attention to natural alternatives. Therefore, in order to increase the shelf life and quality characteristics of meat, new processing technologies and new ingredient systems that are associated with natural and organic foods are applied. These results demonstrate the potential combined use of grape seed extract and Zataria multiflora Boiss essential oil to the meat industry in the development of novel healthy meat products with improved shelf life and superior product quality. © 2015 Wiley Periodicals, Inc

Change agents’ orientations to change: Experience from Pakistan

In this article, I report on a qualitative study conducted in the rural, mountain district of Chitral, Pakistan. The study examined 5 Teacher Educators (TEs’) specific actions and methods (strategies) and their underlying assumptions and core values (orientations) of change in schools. These TEs work as change agents in the schools established by the Aga Khan Education Service, Pakistan (AKES,P) in partnership with local communities. The TEs’ mandate from AKES,P insists that educational change and community development must go hand-in-hand. They therefore play a unique role as both educational reformers and community developers, stimulating change in schools on the one hand and in local communities on the other. The study’s findings captured three realms of the TEs’ world: a) the TEs’ evolving role as external change agents, b) their preferred strategies for change, and c) their conceptual underpinnings of change in schools. However, in this article, I discuss only one realm of the TEs’ world, i.e., their change orientations. I, therefore, first provide a brief portrayal of the TEs, revealing how their role is defined in the organization. I also describe the research methods employed in this study highlighting the research paradigm, inquiry question and theoretical framework, and research participants. I then discuss and analyze the TEs’ conceptual orientations to change

Comparing the effects of alcoholic extract of ginseng with itraconazole against Candida albicans and Candida krusei

Background: Candidiasis is a prevalent disease which is caused by different species of Candida. Herbal drugs (e.g. ginseng) were traditionally administrated for the treatment of different diseases. This study was carried out to compare the effect of alcoholic extract of ginseng with Itraconazole against Candida albicans (C. albicans) and Candida krusei (C. krusei). Material and Methods: This cross-sectional study was crried out on 22 and 8 species of C.albicans and 8 C.krusei, respectively which were isolated from vagina, urine and sputum of the patients. Using the CLSI M27 and disk diffusion methods the susceptibility test was done by Itraconazole (10 &micro;g) and ginseng extract (1, 2, 4, 8, 16, 32, 64 and 128 mg.ml-1). The standard species of C. albicans (PTCC 5027) and C. Krusei (PTCC 5295) were used for the quality control purposes. Results: The lowest and highest minimum inhibitory concentration (MIC) for C. albicans and C. Kruzei was 0.0625 and 0.5 &mu;g.ml-1, respectively for Itraconazole using the microdilution method. However, the lowest MIC and minimum fungal concentration (MFC) for alcoholic extract was 64 mg.ml-1 .The highest inhibition zone for C. albicans was 14 and 14-32 mm for alcoholic extract and Foritraconazole, respectively. Using the two methods no significant difference was seen between the alcoholic extract of ginseng (64 and 128 mg.ml-1) and the drug. (P&lt;0.05) Conclusion: Considering the MICs and disk diffusion results, the ginseng extract (64,128 mg.ml-1) shows considerable antifungal effects compared to Itraconazole
