A Practical Approach in Digitizing Analogue Audio Assets

Today, Broadcast companies are migrating from aTape-based workflow to that File-Based .This not only affectsgrowing number of channels and new ways of broadcasting, butalso it changes the way we store and retrieve our preciouscontents. Such historical essences are transferred to digital onlyonce and used numerous of times, so the method we use fortransferring these materials is so important. Technicalparameters of digitizing from Capturing and scanning to Storagemedia and formats are as important as non-technical conceptslike metadata and Cataloguing. In this paper, a practical methodof transferring Analog materials to digital formats and media ispresented. Suitable formats, backup, metadata and qualitycontrol methods are introduced. A very best practice of digitizingproject at IRIB huge archive will be introduced as a practicalexample

Analysis of statistical properties of chaos based image encryption by different mappings

Chaos mappings attracted a lot of research in recent years because of good properties of chaos maps in terms of continuous broad band power spectrums, sensitivity to initial conditions and similarity to random behavior. Many different scheme and algorithms have proposed in image encryption by chaos maps as well as different mappings. Not only can the structure of algorithm effect on statistical properties of image encryption, but also different chaos maps can, because of different dynamical properties. PWLCM has attracted a lot of research on recent years regarding good dynamical properties. In following sections, the statistical properties of Yoon algorithm [7] will analysis with PWLCM to conclude better statistical properties and better key space

Effects of embryo induction media and pretreatments in isolated microspore culture of hexaploid wheat (Triticum aestivum L. cv. Falat)

Isolated microspores of many plants can be induced in vitro to switch their developmental process from the gametophytic to a sporophytic pathway under appropriate conditions and produce haploid plants. This research reports the effects of cold pretreatment with or without either mannitol orchemical + heat and also the effects of 5 embryo induction media (NPB-99, C17, W14, CHB-2 and P2) on embryo production, percentage of total and green plant regeneration in isolated microspore culture of an Iranian spring bread wheat, cultivar ‘Falat’. The results showed that combination of 21 days cold (4°C) with mannitol (0.3 M) produced the highest number of embryos/spike while the combination of cold with chemical + heat produced the lowest number. In the case of total and green plant regeneration, "7 days cold + mannitol" was more superior than other pretreatments. NPB-99, W14 and C17 media produced the highest number of embryos/spike, while CHB-2 medium appeared to be a better medium for green plant regeneration

Sex Differences in the Effect of Inflammation on Subjective Social Status: A Randomized Controlled Trial of Endotoxin in Healthy Young Adults.

It has been established that inflammation leads to a variety of changes in social experience, but one area of social experience that has been overlooked is subjective social status. Furthermore, given sex differences in the relationship between inflammation and social status, males may be more sensitive to inflammation-induced changes in social status. However, no previous studies in humans have examined this possibility. In the present study, healthy young participants (n = 115) were randomly assigned to receive either endotoxin, an experimental inflammatory challenge, or placebo. Participants reported their subjective social status at baseline (prior to injection), and approximately 2 h later (time of peak inflammatory response for the endotoxin group). Results, using ANCOVA analyses, indicated that males exposed to endotoxin, but not females, reported lower levels of subjective social status at the peak of inflammatory response (vs. placebo). These results suggest that males may be more sensitive to the effects of inflammation in certain social domains, such as perceived social status.

In Sickness and in Health: The Co-Regulation of Inflammation and Social Behavior

Although it has commonly been assumed that the immune system and the processes that govern social behavior are separate, non-communicating entities, research over the past several decades suggests otherwise. Considerable evidence now shows that inflammatory processes and social behavior are actually powerful regulators of one another. This review first summarizes evidence that inflammatory processes regulate social behavior, leading to characteristic changes that may help an individual navigate the social environment during times of sickness. Specifically, this review shows that inflammation: (1) increases threat-related neural sensitivity to negative social experiences (eg, rejection, negative social feedback), presumably to enhance sensitivity to threats to well-being or safety in order to avoid them and (2) enhances reward-related neural sensitivity to positive social experiences (eg, viewing close others and receiving positive social feedback), presumably to increase approach-related motivation towards others who might provide support and care during sickness. Next, this review summarizes evidence showing that social behavior also regulates aspects of inflammatory activity, preparing the body for situations in which wounding and infection may be more likely (social isolation). Here, we review research showing: (1) that exposure to social stressors increases proinflammatory activity, (2) that individuals who are more socially isolated (ie, lonely) show increased proinflammatory activity, and (3) that individuals who are more socially isolated show increased proinflammatory activity in response to an inflammatory challenge or social stressor. The implications of the co-regulation of inflammation and social behavior are discussed

A pilot study examining physical and social warmth: Higher (non-febrile) oral temperature is associated with greater feelings of social connection

An emerging literature suggests that experiences of physical warmth contribute to social warmth - the experience of feeling connected to others. Thus, thermoregulatory systems, which help maintain our relatively warm internal body temperatures, may also support feelings of social connection. However, the association between internal body temperature and feelings of connection has not been examined. Furthermore, the origins of the link between physical and social warmth, via learning during early experiences with a caregiver or via innate, co-evolved mechanisms, remain unclear. The current study examined the relationship between oral temperature and feelings of social connection as well as whether early caregiver experiences moderated this relationship. Extending the existing literature, higher oral temperature readings were associated with greater feelings of social connection. Moreover, early caregiver experiences did not moderate this association, suggesting that the physical-social warmth overlap may not be altered by early social experience. Results provide additional support for the link between experiences of physical warmth and social warmth and add to existing theories that highlight social connection as a basic need on its own

Caring Burden and Quality of Life of Family Caregivers in Patients Undergoing Hemodialysis: A Descriptive-Analytic Study

Background: Caring role, especially in chronic diseases, has a negative impact on the health of family caregivers and can affect their quality of life. Therefore, this study aimed to investigate the care burden and quality of life in family caregivers of hemodialysis patients and their relationship with some characteristics of caregivers and patients. Methods: This study was conducted as a descriptive-analytic study in Isfahan from January to February 2017. Sampling was done using census. The number of participants was 254. The data gathering tools consisted of a three-part questionnaire including demographic characteristics, the Zarit questionnaire for caring burden, and SF-36 quality of life questionnaire. Data were analyzed using descriptive statistics, Pearson correlation coefficient test, Spearman’s coefficient, ANOVA, and univariate general linear regression. A significant level of 5% was considered. Results: The mean scores of the quality of life and caring burden were 30.54±9.89 and 44.98±6.82, respectively in caregivers. The age of the patient under care (P<0.001), cost of medications (P=0.008), and hours of care in 24 hours (P<0.001) had a significant relationship with care givers’ quality of life. Also, univariate general linear regression revealed that care burden had a significant relationship with the quality of life (P=0.003). Conclusion: Family caregivers who experienced more caring burden had a low quality of life. The researchers suggest that supportive and educational programs should be designed and implemented for this group of patients and their caregivers

The role of a new electromagnetic shielding in reducing the microwave radiation for the X-band frequencies

Background and aims: X-band microwave with 8-12.5 frequency range has various applications such as air control traffic, navy communication etc. Uncontrolled exposure with microwave can lead to adverse effect on workers. Application of the shielding is superior control for prevention of microwave exposure. The aim of this study is production a new electromagnetic shielding for exposure control of X-band frequency by nano nickel oxide and epoxy resin. Methods: Nanocomposites prepared by epoxy resin and nano nickel oxide (7 wt) with 2, 4 and 6 mm thicknesses. Nanoparticles characterized by XRD and FESEM. Shielding effectiveness measured with vector network analyzer. Results: The Average of shielding effectiveness for three thicknesses were 2.68, 5.09 and 5.35 dB respectively that were equivalent to 45.98, 69.01 and 70.87 attenuation percentage. Maximum attenuation (8.96 dB or 87.29 attenuation percentage) obtained by the nanocomposite with 6mm thickness at 8.51 GHz frequency. The Average of shielding effectiveness increased with increasing the thickness. Conclusion: these nanocomposites could be used as appropriate shielding for exposure control of X-band frequency in workplace.Both Epoxy and nanocomposite with 6mm thicknesses are useful in specific frequency such as 8.52 and 8.51 GHz. However, According to economical and technical issues, nanocomposite with 4mm thickness is appropriate shield in this study. In according to required attenuation and economical benefit, attenuation matrix can be used for selecting the appropriate electromagnetic shield
