Opis:
W artykule opisano historię działalności, program i twórców audycji w języku polskim emitowanych przez radiofonię włoską od lat czterdziestych XX wieku po pierwsze dziesięciolecie obecnego stulecia. Programy te kierowane były do Polaków mieszkających na Półwyspie Apenińskim, w ojczyźnie i innych krajach, a obecnie wiedza na ich temat jest niewielka, dostępna z zachowanych częściowych zasobów archiwalnych, zapisów w polonikach włoskich i wywiadów z niektórymi ich autorami. Audycje polskojęzyczne w Radiu RAI stanowią istotny fragment historii mediów polonijnych i polskojęzycznych na świecie.
The article describes the history of the activity, the program and authors of programs in Polish broadcasted by Italian radio from the 1940s to the first decade of this century. These programs were directed to Poles living in the Apennine Peninsula, in their own homeland and in other countries, and at present a little knowledge about them is available from the preserved partial archival resources, the records in Italian Polonica and the interviews with some of their authors. Polish-language broadcasts on Radio RAI constitute an important part of Polonia and Polish-language media around the world.

Opis:
A recently developed successful approach to achieve the balance of properties involves the copolymerization of film forming monomers like acrylates and methacrylates. The copolymerization of acrylate based monomer having different alkyl group offers the opportunity to study the effect of the alkyl substituents on the polymer properties. The objective is to study their copolymerization behavior with acrylate or combination of acrylates of varying chemical nature using free radical initiator and to correlate the composition of the copolymers with their physical properties suitable for its use as coating on hard surfaces.

Opis:
Singular surface theory is applied to study the growth and decay properties of weak magnetogasdynamic discontinuities under the influences of thermal conduction and the time-dependent radiation field interacting with magnetogasdynamic field with finite electrical conductivity. It is shown that the time-dependent radiation field gives rise to a radiation induced weak wave which is always damped and the magnetogasdynamic waves which break at the wave front if the initial discontinuity is sufficiently strong. The wave front curvature effects on the weak magnetogasdynamic waves are also discussed.

Opis:
The Weibull distribution is used to describe various observed failures of phenomena and widely used in survival analysis and reliability theory. Sometimes it is very difficult to compute moments of such distributions due to various reasons for e.g. analytical issues, multi parameter cases etc. This study presents the computation of the moments and the expected value of the product of order statistics in the sample from the one-parameter Weibull distribution. An alternative approach in connection to survival function is used to obtain these moments and expected values. In addition the characteristic function of the above distribution is also obtained in the form of gamma functions. Further an illustration is shown to find the first two moments and expected value of the product of order statistics by using this approach.

Opis:
In this work, a real-time label-free microwave sensing mechanism for glucose concentration monitoring using a planar biosensor configured with an inset fed microstrip patch antenna has been demonstrated. A microstrip patch antenna with the resonating frequency of 1.45 GHz has been designed and is fabricated on the Flame Retardant (FR-4) substrate. Due to the intense electromagnetic field at the edges of the patch antenna, edge length has been used as the detecting area where the sample under test (SUT) interacts with the electromagnetic field. The Poly-Dimethyl-Siloxane (PDMS) with the trench in the centre has been employed as the sample holder. Here, the SUT is the glucose dissolved in DI (de-ionized) water with the concentration range of 0.2 to 0.6 g/mL. The dielectric constant dependency on the glucose concentration has been used as the distinguishing factor which results in a shift in the S-parameter. The experimentally measured RF parameters were observed closely which showed the shift in S11 magnitude from -40 to -15 dB and resonant frequency from 1.27 to 1.3 GHz w.r.t the SUT solution of 0.2 to 0.6 g/mL with linear regression coefficient of 0.881, and 0.983 respectively.

Opis:
Monitoring of surgical outcome is increasingly important part of governance of surgical activity. The aim of the study. POSSUM scoring system was applied prospectively to determine how it performed in predicting morbidity and mortality in patients undergoing emergency laparotomy in our hospital, a group known to be at high risk of complications and death. Material and methods. A total of 100 cases of emergency laparotomies were studied in patients admitted in general surgery department during the period of May 2008 to August 2010. The study group consisted of the following cases. Duodenal perforation (37 cases), intestinal obstruction (27 cases), gastric perforation (8 cases), ileal perforation (8 cases), appendicular perforation (7 cases), blunt trauma (4 cases) and others (9 cases). They were scored using POSSUM scoring system. Physiological scoring was done at the time of admission and operative scoring was done intraoperatively. They were followed up for the first 30 day post operative period for any complications and the outcome was noted. The observed morbidity and mortality rates were compared with the POSSUM predicted morbidity and mortality rates. Results. 15 patients died (mortality rate of 15%). The POSSUM predicted mortality was 20 deaths. O:E ratio of 0.71 was obtained. There was no statistically significant difference between the observed and predicted mortality rates (χ2=1.72, p=0.974). 71 patients experienced complications. The POSSUM predicted morbidity was 61 patients. O:E ratio of 1.19 was obtained. There was no statistically significant difference between the observed and predicted morbidity rates (χ2=1.594, p=0.991). Conclusions. POSSUM scoring is an accurate predictor of mortality and morbidity following emergency laparotomy and is a valid means of assessing adequacy of care provided to the patient. POSSUM can be used for surgical audit to assess and improve the quality of surgical care and helps in better outcome to the patient

Opis:
The broad biocontrol properties of myxobacteria (mainly members of the genera Corallococcus and Myxococcus) isolated from forest soils against main fungal pathogens of pine seedlings were estimated. Among the myxobacterial strains studied (in vivo tests), the strongest antagonism towards fungi was noticed for the strains of the species Myxococcus virescens Thaxter and Corallococcus exiguus Reichenbach. They inhibited the fungal growth within the range 38–63%. The strongest inhibitory reaction towards Cylindrocarpon destructans (Zinssm.) Scholten was observed. A predominating part of myxobacteria (22 from among 30) inhibited the growth of Rhizoctonia solani Kühn. Myxobacteria suppressed any pathogenic action of Rhizoctonia solani (strain 411) towards Scots pine seedlings (in vitro tests). They produced extracellular (but not intracellular) acidic and neutral proteinases. None of the myxobacterial strain under examination produced chitinases. The 57% of the myxobacterial strains studied produced siderophores. The numbers of myxobacterial strains, obtained from under forest trees were in the following order: Betula pendula Roth. > Pinus sylvestris L. > Alnus glutinosa Gaertn. = Quercus robur L. The results gained in present work have proved potential use of myxobacteria as biocontrol agents against Rhizoctonia solani, common fungal pathogen of pine seedlings.

The tongue plays a vital role in deglutition, taste and speech. An abnormality or unhealthy tongue would make food intake troublesome, thereby depriving the individual of adequate essential nutrients. A fissured tongue is a malformation characterized by furrows or grooves on the dorsum of the tongue. On the other hand, geographic tongue is a benign recurrent condition of uncertain aetiology affecting the tongue characterized by loss of epithelium especially filiform papillae giving a characteristic appearance. These conditions may be asymptomatic or cause of discomfort to the patient. There are seldom case reports in literature of having seen these two conditions concurrently.

Opis:
Designing a finite impulse response (FIR) filter with minimal group delay has proven to be a difficult task. Many research studies have focused on reducing pass band and stop band ripples in FIR filter design, often overlooking the optimization of group delay. While some works have considered group delay reduction, their approaches were not optimal. Consequently, the achievement of an optimal design for a filter with a low group delay value still remains a challenge. In this work, a modified differential search optimization algorithm has been used for the purpose of designing a minimal group delay FIR filter. The results obtained have been compared with the classical techniques and they turned out to be promising.

Opis:
The study aims to examine the role of Self-Forgiveness in shaping the Human Flourishing of the adults. Two hundred fourteen participants (18 to 30 years) comprising 100 males (Mean Age = 22.15(1.61)) and 114 females (Mean Age = 22.00(1.95)) were chosen for the study. Self-forgiveness (Mudgal & Tiwari, 2017a) and Mental Health Continuum-Short Form (Keyes, 2005) were used as the tools. Self-forgiveness comprises Realization & Reparation, Guilt, Attribution and overall self-forgiveness (sum of the first three) while Human Flourishing consists of Hedonic and Eudaimonic (Social plus Psychological) Well-Being. The aggregate of Hedonic and Eudaimonic is overall Human Flourishing. The findings suggested no gender differences in Self-Forgiveness of the participants. Conversely, gender differences were observed in all the dimensions of Human Flourishing in favour of males. Irrespective of gender, Realization & Reparation was positively correlated with Hedonic, Social, Psychological and Eudaimonic Well-Being as well as Human Flourishing except for Guilt and Attribution that showed small positive or negative correlations. Irrespective of gender, Overall Self-Forgiveness correlated positively with all the dimensions of Flourishing. Gender and Realization & Reparation emerged as the significant predictors accounting for significant variance in all the dimensions of Flourishing while Guilt and Attribution did not. The findings suggested that remorse, easy acceptance of wrongdoing, repairing the relationship with self and others, ability to minimize negative emotions towards self, monitoring others’ positive behaviours and acknowledgements of valued and close relationships were the psychological mechanisms that may underlie the predictive strengths of self-forgiveness in regulating flourishing.

This will soothe the needs of urban commuters and thereby saving unnecessary spillage of money on the construction projects. In this research project, we present an artificial intelligence framework for transport video analytic; which autonomously models behavioural patterns of commuters and flow of traffic, wherein it taxonomically classifies essential patterns based on geometrical feature points of interest to facilitate reality mining. This behavioural pattern of commuter and traffic flow can later be queried and fetched through the newly mathematically programmed ontological data warehousing module, where such reality mined contextual data could be used for sharing essential data.

Opis:
1,3,6,8-tetranitro carbazole (TNC) as a secondary explosive is used in composite explosive formulations in order to reduce the sensitivity and increase the stability of the explosive composites. In this work, the thermal stabilities of pure TNC and its nanocomposites prepared via three different nanoparticles were studied by thermal analysis, i.e. differential scanning calorimetery (DSC) and thermogravimetry (TG) techniques. Thermal analysis data revealed that the thermal behavior of pure TNC is significantly different from the nanocomposites studied. Pure TNC decomposed completely during a single step in the temperature range 385-425 °C. However, the addition of nanoparticles to the TNC powder leads to higher thermal stability in comparison with the pure TNC. The decomposition kinetics of TNC and its nanocomposites were studied by non-isothermal DSC at several heating rates. Thermokinetic and thermodynamic parameters corresponding to the thermal decomposition of pure TNC and nanocomposites were computed and compared. The results showed that the addition of nanoparticles to the TNC powder has a considerable effect on the thermal stability of the explosive.

Opis:
arious methods of constructing nested ternary and quaternary efficiency balanced and variance balanced designs are proposed by applying some repetitions of treatments in all possible pairs of treatments. In these designs sub-blocks and super-blocks may form different p-ary designs, where sub-blocks have higher efficiency as compared to super-blocks, i.e., any two elementary treatment contrasts in the sub-blocks can be measured with higher efficiency than any two elementary contrasts in the super-block structure. A comparison is shown in Table 1.

Opis:
The study examined the relationships among some demographic factors, self-compassion and interdependent happiness of the married Hindu couples. Using a correlational research design, 600 participants (300 couples) were chosen by a snowball sampling. Self-compassion Scale (Neff, 2003b), Socioeconomic Status Scale (Aggarwal et al., 2005) and Interdependent Happiness Scale (Hitokoto & Uchida, 2015) were used to collect data. Findings revealed that some demographic factors such as age, years of marriage and number of family members were positively correlated with self-compassion while the number of children and socioeconomic status were negatively correlated with it. Age, years of marriage and the number of children had a positive relationship with interdependent happiness. Self-compassion evinced a significant positive correlation with the interdependent happiness of the couples. The nature of family and self-compassion accounted for significant variance in the scores of interdependent happiness of the couples. The study constitutes one of the limited studies which assessed the relationships among a set of demographic factors, self-compassion and interdependent happiness on a sample drawn from a collectivistic society. The results have been discussed in the light of extant theoretical and empirical findings of self-compassion and interdependent happiness. The findings may have significant implications for understanding positive life outcomes of people with self-compassion belonging to a collectivistic culture. The theory, practise and policy implications of the findings have been discussed. Directions for future research have also been provided along with some limitations of the study.

Opis:
Estimation techniques for a domain parameter play a very significant role in the theory of sample surveys. In the recent years many advanced methodologies have been developed for domain estimation. In particular, direct and synthetic estimators are applied for the estimation of domain mean in the government and private sectors under certain assumptions as to the size of the samples relating to particular domains. The findings demonstrate that the direct estimator fails to perform more efficiently as compared to the synthetic estimator when reliable units are not directly accessible in the studied domains. Moreover, due to the fact that small units belong to the sample of the studied domain, the direct estimator produces an unacceptably large standard error. In contrast, if a sufficient number of units are available in the studied domain, the direct estimator produces effective results. This paper presents the theoretical aspects of the proposed class of direct estimators for domain mean with the use of a single auxiliary character, compared with an existing direct ratio estimator for domain mean (given in section 3.2). In addition, an empirical study has been provided to support the validity of the proposed estimators. The findings prove that the proposed estimators outperform the direct ratio estimator for domain mean using a single auxiliary character in the case of two studied populations and their analysed domains considered from Sarndal et al. (1992).

Opis:
An integrated study based on calcareous nannofossils, organic-walled dinoflagellate cysts, and ammonites from the Washtawa and Kanthkot formations of the Wagad Uplift have allowed a detailed documentation of the stratigraphic position of these formations within the Oxfordian and Kimmeridgian sediments of the Kachchh Basin, western India. The nannofossil assemblages from the lower part of the Nara Shale Member exposed in the Nara and Washtawa domes, the Kanthkot Ammonite Beds along the Trambau River section, and the Patasar Shale Member exposed along the Trambau River section and the Patasar Tank section in the eastern part of the Wagad Uplift belong to the NJ 14 Cyclagelosphaera margerelli Zone of the Early Oxfordian, the NJ 15a Lotharingius sigillatus Zone of the Middle Oxfordian, and the NJ 15b Cretarhabdus conicus of Early Kimmeridgian age, respectively. Zonation schemes, based on calcareous nannofossils, dinoflagellate cysts, and ammonites were calibrated highlighting their biostratigraphic potential. These studies may represent a reference biochronology for Oxfordian–Kimmeridgian age strata applicable to the Tethyan realm of which India was a part during Late Jurassic times.
