Opis:
Background: Security has become more of a concern with the wide deployment of Internet-of-things (IoT) devices. The importance of addressing security risks early in the development lifecycle before pushing to market cannot be over emphasized. Aim: To this end, we propose a conceptual framework to help with identifying security concerns early in the product development lifecycle for Internet-of-things, that we refer to as SIoT (Security for Internet-of-Things). Method: The framework adopts well known security engineering approaches and best practices, and systematically builds on existing research work on IoT architecture. Results: Practitioners at a Norwegian start-up company evaluated the framework and found it useful as a foundation for addressing critical security concerns for IoT applications early in the development lifecycle. The output from using the framework can be a checklist that can be used as input during security requirements engineering activities for IoT applications. Conclusions: However, security is a multi-faced concept; therefore, users of the SIoT framework should not view the framework as a panacea to all security threats. The framework may need to be refined in the future, particularly to improve its completeness to cover various IoT contexts.

Opis:
In order to survive periods of adverse cold climatic conditions, plant requirements are satisfi ed by means of physiological adaptations to prevent cells from freezing. Thus, the growth of woody plants in temperate regions slows down and they enter into a physiological state called dormancy. In order to identify the chilling and heat requirements to overcome the dormancy period of Cupressaceae pollen type in the south of Europe, we have carried out our study with aerobiological data from a 10-year (1996- 2005) period in Ponferrada, León (Spain). For the chilling requirements the best result was with a threshold temperature of 7.1ºC and an average of 927 CH. Calculation of heat requirements was carried out with maximum temperature, with 490 growth degree days (GDD) needed, with a threshold temperature of 0ºC. We have used the 2002-2003, 2003- 2004 and 2004-2005 periods in order to determine the real validity of the model. We have not used these years in developing the models. The dates predicted differ in only a few days from those observed: in 2002-2003 there was a difference of 11 days, in 2003-2004 predicted and observed dates were the same, but in 2004-2005 the difference obtained was of 43 days.

Jerusalem artichoke
Opis:
The Jerusalem artichoke is a plant which has great potential as a crop food and forage, or as a raw material in alcohol industry. Energy requirement to produce ethanol from this crop is prepared for farm-size operation. It is one of the most efficient crops for ethanol production from a net energy viewpoint.
Produkcja etanolu przez fermentację odnawialnych, bogatych w węglowodany surowców roślinnych jest ciągle przedmiotem badań na całym świecie. Etanol jest bowiem nie tylko alternatywnym zamiennikiem ropy naftowej w sensie energetycznym, ale również substratem do wielu syntez chemicznych. Powszechne stosowanie etanolu jest jednak ciągle kontrowersyjne, gdyż część badaczy twierdzi, iż jego produkcja jest energetycznie nieefektywna. W niniejszej pracy wykazano, że użycie wysokoplennego surowca roślinnego do produkcji etanolu w gorzelniach rolniczych i wykorzystanie przy przerobie tego surowca wszystkich uzyskiwanych produktów zapewnia energetyczną opłacalność procesu. Takim właśnie surowcem roślinnym jest bulwa, ze względu na jej wysoką plenność (tab. 1), jak i korzystny skład chemiczny (tab. 2). Dzięki uprawie bulwy z powierzchni uprawnej można uzyskać odpowiednio 1,7, 2,0 i 3,7 raza więcej etanolu niż z uprawy buraka cukrowego, kukurydzy bądź zbóż. Bulwa cechuje się relatywnie małymi wymaganiami w stosunku do siedliska, jest odporna na większość szkodników i zaraz, jak również na niską temperaturę. Do analizy energetycznej procesu zastosowano zintegrowany model produkcji etanolu w skali gorzelni rolniczej (rys. 1). Model uwzględnia ilości energii wydatkowane w trakcie uprawy bulwy (tab. 3) i w trakcie jej przerobu na etanol (rys. 2 i tab. 4). Z przeprowadzonego bilansu energetycznego wynika (tab. 5), że uzyskuje się znaczny zysk energetyczny, gdyż stosunek ilości energii uzyskiwanej do ilości energii włożonej wynosi ok. 3, 7.

Introduction and aim. Vitamin-A-deficiency is a public health problem among preschool children of Nigeria. Study determined the contribution of bread and biscuits to vitamin A-daily-requirement of preschool children in Lagos-State, Nigeria. Material and methods. A community-based-study using a cross-sectional-design with analytical component was carried out from 2013-2015. Multi-stage-sampling-technique was used to select mothers of preschool-children (n=1599) in 5 Local-Government-Areas of Lagos. Respondents’ socio-demographic information and samples consumption-pattern were collected using validated, food-frequency-questionnaire/dietary recall. Retinyl palmitate content of randomly selected commonly-consumed brands of oven-fresh-bread stored for 5-days and biscuits (30- to 60-days) at prevailing outdoor-market-temperatures were analysed using High-Performance-Liquid-Chromatography. Contribution to preschool children’s vitamin A-daily-requirements were determined. Data were analysed using Student’s t-test and ANOVA at p<0.05. Results. Mean age of preschool children was 31.44±5.28 months. Mean intakes of samples were bread (117.6 ±15.9 g/d) and biscuits (59.8±27.9 g/d). Range of contribution to vitamin-A-daily-requirement of preschool-children was 0-178.4 %. Samples contribution to vitamin A-daily-requirement of pre-school-children were oven-fresh bread (68.3 %); 5 days bread (20.7%); 30-days biscuits (25.0%) and 60-days biscuits (6.8%). Overall contribution to vitamin A-daily-requirement were bread (51.4%) and biscuits (22.4%). Statistically significant difference existed between samples contribution and vitamin-A-daily-requirement of preschool children. Conclusion. Bread and biscuits samples contributed significantly to the vitamin-A-daily-requirement of preschool children.

Opis:
There exists an inadequate research on the propagation and nutrient needs of most tropical tree species. Hence, this work involves the developmental impact of soil amendments on the early growth of Streculia setigera Del. in the nursery. Different soil amendments; poultry waste (F1), goat manure (F2), cow manure (F3) and the control, normal soil (F4) were applied to several viable seeds of Streculia setigera in the nursery. The seeds were subjected to the same routine nursery practices. The experiment was laid in a Completely Randomized Design (CRD) and lasted for ninety (90) days. Descriptive statistics and ANOVA were used in the data analysis. The findings revealed that the entire growth response of Streculia setigera seedlings were only sparely affected by the soil amendments (P<0.05). F3 was found to be the most preferred soil amendment for this species, followed by F2 and F4 consecutively. The result obtained from F1 was very poor and thus it is not ideal for this species.

The present work addresses the topic of die clamping at the forging hammer in the context of the definition of a current requirement profile as well as the evaluation of individual influencing variables on the clamping process. In addition to the presentation of survey results for the requirements profile, the first part focus on the sensible minimization of influencing variables to be investigated and on the verification of a possible evaluation method. Based on this, in the second part exemplary influencing variables on the clamping condition are investigated by means of FEM. Thereby it can be shown by way of example, that the heat flow of the forging process and the friction conditions between the clamping elements have a noteworthy influence on the clamping condition of the dies and that deviations in the clamping force can lead to significant damage.

Opis:
Brucella canis infection is one of the most important causes of infertility in dogs and is a zoonosis for which no effective treatment or vaccines exist. It is not a mandatory notifiable disease. Following an increase of cases in Europe and worldwide, an investigation was performed to evaluate how much Italian and Polish veterinarians and breeders know about canine brucellosis and understand their perceptions of this infection. For this reason, two questionnaires were prepared, in Italian and Polish. Eighteen Italian and Polish veterinarians, specialists in canine reproduction, responded to the first survey and 44.4% of them affirmed having diagnosed canine brucellosis at least once in their clinical practice, and different perceptions emerged regarding the infection in the two countries. The second survey was completed by 145 Italian and Polish breeders; the disease was completely unknown to 22.8% of them, whereas 2.1% had diagnosed infection by B. canis in their kennels. In conclusion, knowledge of B. canis infection differs between these countries, with extremes ranging from diagnosed cases to complete underestimation of the presence of the problem. However, based on international data and reporting of a recent large outbreak in Italy, awareness of this contagious infectious disease and its management must be increased.

Opis:
A reading of many recent publications shows that theoretical concerns in the field of linguistics have declined, even though the founders of the discipline all emphasised the central importance of its role. This article aims to show how linguistic description has progressed thanks to the different theoretical tools that have been developed in the course of research. From this point of view, this article illustrates the following facts: lexicon, semantics and syntax are not separate instances but together form the units that are sentences. The elements of sentences must be described in terms of the set of properties that characterise them. This is the case for regular sequences. Finally, one of the promising objectives consists in finding a reasoned classification of fixed sequences. Linguistics, like any science, cannot do without theoretical tools.

Individual total energy expenditure may be calculated as a sum of basal energy requirement and energy expenditure associated with physical activity. Measurement of basal energy requirement is not often conducted in dietetic practice, but may be applied using indirect calorimetry. The aim of the analysis was to present the possibilities of using the Fitmate PRO monitor in the assessment of resting metabolic rate and basal energy expenditure with a method of indirect calorimetry in a group of 91 overweight and obese women in various age. The mean results of the resting metabolic rate measured with method of indirect calorimetry using the Fitmate PRO monitor did not differ in the age groups of overweight and obese women. The results of the resting metabolic rate measured with method of indirect calorimetry using the Fitmate PRO monitor were correlated with body mass, height, fat mass, muscle mass and waist circumference. The Fitmate PRO monitor may be a valuable tool in everyday dietetic practice to assess the basal energy expenditure with method of indirect calorimetry in a group of overweight and obese women.

Opis:
Greenhouses are artificial growing environments that can provide the growth factors required for the production of crop plants out of season. In these structures, the low temperature values that occur during the year cause losses in yield and quality because they are not suitable for plant cultivation. In order to be able to grow out of season in these periods, the amount of heat required by the plants should be provided with additional heating. In the study carried out to determine the amount of heat needed in greenhouses throughout the year for the provinces of Kırşehir and Kahramanmaraş, which are located in two different regions of Turkey, the heat requirements that will arise in the presence or absence of a thermal screen in greenhouses with the same characteristics were calculated. In the calculations, the most common tomato plant grown in both provinces has been considered. Accordingly, if the greenhouse temperature is kept at a constant temperature of 18°C throughout the year, the heat energy requirements that emerge during the year are 469.90 kWh m.-2 for Kırşehir and 254.71 kWh m.-2 for Kahramanmaraş. In the case of using a thermal screen, these values were calculated as 401.53 kWh m.-2 for Kırşehir province and 218.91 kWh m.-2 for Kahramanmaraş province. As a result of the study, the amount of heat energy needed in greenhouses in provinces decreased with the use of thermal screens. It has been determined that this situation is extremely important in terms of reducing the share of heating in production costs and the amount of carbon dioxide released into the atmosphere by fossil energy sources used for heating purposes.

Opis:
Background: The comprehensive representation of functional requirements is a crucial activity in the analysis phase of the software development life cycle. Representation of a complete set of functional requirements helps in tracing business goals effectively throughout the development life cycle. Use case modelling is one of the most widely-used methods to represent and document functional requirements of the system. Practitioners exploit use case modelling to represent interactive functional requirements of the system while overlooking some of the non-interactive functional requirements. The non-interactive functional requirements are the ones which are performed by the system without an initiation by the user, for instance, notifying something to the user or creating an internal backup. Aim: This paper addresses the representation of non-interactive requirements along with interactive ones (use cases) in one model. This paper calls such requirements 'operation cases' and proposes a new set of graphical and textual notations to represent them. Method: The proposed notations have been applied on a case study and have also been empirically evaluated to demonstrate the effectiveness of the new notations in capturing non-interactive functional requirements. Results and Conclusion: The results of the evaluation indicate that the representation of operation cases helps in documenting a complete set of functional requirements, which ultimately results in a comprehensive translation of requirements into design.

A multi-criteria model for determining the order size for materials used in production has been presented. It was assumed that the consumption rate of each material is a random variable with a known probability distribution. Using such a model, in which the purchase cost of materials ordered is limited, three criteria were considered: order size, probability of a lack of materials in the production process, and deviations in the order size from the consumption rate in past periods. Based on an example, it has been shown how to use the model to determine the order sizes for polyurethane adhesive and wood in a hard-coal mine.
