Mathematical Models to Predict Staphylococcus aureus Growth on Processed Cheeses

This study developed predictive models for the kinetic behavior of Staphylococcus aureus on pro- cessed cheeses. Mozzarella slice cheese and cheddar slice cheese were inoculated with 0.1 ml of a S. aureus strain mixture (ATCC13565, ATCC14458, ATCC23235, ATCC27664, and NCCP10826). The inoculated samples were then stored at 4 o C (1440 h), 15 o C (288 h), 25 o C (72 h), and 30 o C (48 h), and the growth of all bacteria and of S. aureus were enumerated on tryptic soy agar and mannitol salt agar, respectively. The Baranyi model was fitted to the growth data of S. aureus to calculate growth rate (µmax; log CFU·g �1 ·h �1 ), lag phase duration (LPD; h), lower asymptote (log CFU/ g), and upper asymptote (log CFU/g). The growth parameters were further analyzed using the square root model as a function of temperature. The model performance was validated with observed data, and the root mean square error (RMSE) was calculated. At 4 o C, S. aureus cell growth was not observed on either processed cheese, but S. aureus growth on the mozzarella and cheddar cheeses was observed at 15 o C, 25 o C, and 30 o C. The µmax values increased, but LPD values decreased as storage temperature increased. In addition, the developed models showed acceptable perfor- mance (RMSE = 0.3500-0.5344). This result indicates that the developed kinetic model should be useful in describing the growth pattern of S. aureus in processed cheeses.
The Bilingual Parent as Model for the Bilingual Child (In Commemoration of Prof.Y.Tsuji)

A survey investigated how language management strategies used by bilingual families could create family communication problems. The study was inspired by experience with bilingual families in which rigid adherence to a language policy appeared to impede communication. Respondents were 83 members of a special interest group on bilingualism within a Japanese language teacher's association. The survey explored respondent familiarity with the "one person-one language" strategy in which each parent speaks his own language at home, and home/community language strategy in which parents speak the minority language in the home and children learn the majority language through interactions outside the family. Results suggest that families applying these two language management strategies often face a wide range of problems, especially after the children reach school age and when families have more than one child. An alternative approach is recommended, in which parents make a conscious effort to help their children bridge the gap between two divergent languages and cultures through systematic modeling and promotion of the development of both languages. Specific techniques for achieving this are offered, including modeling, recasting/expansion/filling in the blanks, debriefing, and temporary intensive training. (Contains 15 references.)

The importance of scholar and child travel in South African cities, and a review of improvement measures

In recent years a number of travel surveys have suggested, perhaps unexpectedly, that as many education trips are made in South Africa’s metropolitan cities as work trips. However, much past analysis of travel behaviour and many travel demand models exclude education trip-making. This paper argues that this practice is problematic, and investigates secondary and primary data sources to establish the nature, extent and importance of scholar and child travel. The primary data source takes the form of an activity-based household travel survey administered in 2000 and 2001 in Cape Town. The paper discusses the significance of the available data for understanding the urban passenger transport problem in South Africa in general, and for understanding morning peak congestion and pedestrian safety problems in particular. Considerable attention is being given at present to improving conditions of scholar or child travel in other parts of the world. The paper reviews international measures implemented to alleviate many of the problems associated with child and scholar trip-making, and identifies opportunities for improved practices in South African cities.
Biogeosciences A young afforestation area in Iceland was a moderate sink to CO 2 only a decade after scarification and establishment

This study reports on three years (2004–2006) of measurements of net ecosystem exchange (NEE) over a young Siberian larch plantation in Iceland established on previously grazed heathland pasture that had been scarified prior to planting. The study evaluated the variation of NEE and its component fluxes, gross primary production (GPP) and ecosystem respiration (R e), with the aim to clarify how climatic factors controlled the site’s carbon balance. The young plantation acted as a relatively strong sink for CO 2 during all of the three years, with an annual net sequestration of −102, −154, and−67 g C m−2 for 2004, 2005, and 2006, respectively. This variation was more related to variation in carbon efflux (Re) than carbon uptake (GPP). The abiotic factors that showed the strongest correlation to R e were air temperature during the growing season and soil water potential. The GPP mostly followed the seasonal pattern in irradiance, except in 2005, when the plantation experienced severe spring frost damage that set the GPP back to zero. It was not expected that the rather slow-growing Siberian larch plantation would be such a strong sink for atmospheric CO 2 only twelve years after site preparation and afforestation.
Performance improvement of small Unmanned Aerial Vehicles through gust energy harvesting

Fixed-wing miniature aerial vehicles usually fly at low altitudes that are often exposed to turbulent environments. Gust soaring is a flight technique of energy harvesting in such a complex and stochastic domain. The presented work shows the feasibility and benefits of exploiting a nonstationary environment for a small unmanned aerial vehicle. A longitudinal dynamics trajectory is derived, showing significant benefits in extended flight with a sinusoidal wind profile. An optimization strategy for active control is performed, with the aim of obtaining the most effective set of gains for energy retrieval. Moreover, a three-dimensional multipoint model confirms the feasibility of energy harvesting in a more complex spatial wind field. The influence of unsteady aerodynamics is determined on the overall energy gain along the flight path with active proportional control. The aerodynamic derivatives describing the contribution to lift by a change in angle of attack and elevator deflection are identified as the m.
Modeling population dynamics of solitary bees in relation to habitat quality

Abstract. To understand associations between habitat, individual behaviour, and population development of solitary bees we developed an individual-based model. This model is based on field observations of Osmia rufa (L) (Apoideae: Megachilidae) and describes population dynamics of solitary bees. Model rules are focused on maternal investment, in particular on the female’s individual decisions about sex and size of progeny. In the present paper, we address the effect of habitat quality on population size and sex ratio. We examine how food availability and the risk of parasitism influence long-term population development. It can be shown how population properties result from individual maternal investment which is described as a functional response to fluctuations of environmental conditions. We found that habitat quality can be expressed in terms of cell construction time. This interface factor influences the rate of open cell parasitism as the risk for a brood cell to be parasitized is positively correlated with the time of its construction. Under conditions of scarce food and under resulting long provision times even low parasitism rates lead to a high extinction risk of the population, whereas in rich habitats probabilities of extinction are low even for high rates of parasitism. For a given level of food and parasitism there is an optimum time for cell construction which minimizes the extinction risk of the population. Model results demonstrate that under fluctuating environmental conditions, decreasing habitat quality leads to a decrease in population size but also to rapid shifts in sex ratio.
Bioactive content and antioxidant characteristics of wild (Fragaria vesca L.) and cultivated strawberry (Fragaria × ananassa Duch.) fruits from Turkey

In this study, some biochemical (total soluble solid content, pH, acidity and vitamin C) and in vitro antioxidant activity, total phenolic content, total ellagic acid and concentration of anthocyanins of fifteen wild strawberry genotypes ( Fragaria vesca L.) and one commercial strawberry cultivar Camarosa ( Fragaria × ananassa Duch.) sampled in Northeastern Turkey were determined. Antioxidant activity of fruit samples was determined by DPPH (2,2-diphenyl-1-picrylhydrazyl) and FRAP (Ferric reducing antioxidant power) assays. Notable differences were found both among wild strawberries and also between wild strawberries and cv. Camarosa. Among the strawberry accessions tested, the total phenolics ranged from 138 mg to 228 mg gallic acid equivalent per 100 g fresh fruit. The total monomeric anthocyanin content was the highest in wild genotype FV-2 (53.51 mg/100 g) while the lowest in FV-6 as 25.11 mg per 100 g fresh weight basis. The total ellagic acid content was between 15.18 and 26.36 mg per 100 g. All wild strawberries had higher antioxidant activity than cv. Camarosa. Thus, it can be concluded that wild strawberry is a good source of polyphenols, ellagic acid and antioxidants.
The Recovery Theorem

We can only estimate the distribution of stock returns but we observe the distribution of risk neutral state prices. Risk neutral state prices are the product of risk aversion - the pricing kernel - and the natural probability distribution. The Recovery Theorem enables us to separate these and to determine the market's forecast of returns and the market's risk aversion from state prices alone. Among other things, this allows us to determine the pricing kernel, the market risk premium, the probability of a catastrophe, and to construct model free tests of the efficient market hypothesis.
The Competence Of Young Entrepreneur Candidate In University, Indonesia

Some of the most important issues in the global economy that affect the financial crisis in developing countries. Especially in Indonesia, the firstly is the problem of high unemployment rates, and secondly, the unevenness of opinions caused by education that is irrelevant to the world of work. Based on World Bank data in 2016, there are more than 620 million workers, especially non-working of school alumni, most of who are in Asia and Africa. Entrepreneurship is highly concentrated applied by the government to the entire community, not least in the university. The curriculum of entrepreneurship courses has been developed at public and private universities in Indonesia. The determining of the level of entrepreneurial competence of students in improving the quality of young entrepreneurial candidates in the university. This research is descriptive quantitative. The research subjects are students who have vision and mission based on entrepreneurship. The Questionnaire as a research tool filled by 160 respondents. Data analysis using comparative analysis of t-test method. The results showed that entrepreneurial competence of students explained of the competence to understand the production process and technology in the high category. While the result of t-test method analysis there are significant differences of entrepreneurship competence between a student in public and private university. The level of entrepreneurial competence is very influential on the environment of student learning. The findings of this research will be very important for universities and the Ministry of Education in the terms of strengthening the curriculum of the university education.
Overall Equipment Efficiency (OEE) Enhancement in Manufacture of Electronic Components & Boards Industry through Total Productive Maintenance Practices

In an environment of intense global competition, both creative and proven strategies need to be considered in order to bring about the effectiveness and efficiency in manufacturing operation. Total Productive Maintenance (TPM) is one of the effective maintenance strategy in enhancing the equipment effectiveness and to achieve a significant competitive advantage. This research paper addresses the impact of three TPM pillars namely planned maintenance (PM), autonomous maintenance (AM) and focused maintenance (FM) on overall equipment effectiveness (OEE) of die attach equipment in the production line of semiconductor industry. The effect of TPM on the OEE is also investigated depending on the equipment types, in where die attach process consist of two models-CANON and ESEC. The primary data was collected from an organization's database and was analysed by SPSS V23. The preliminary results of the analysis showed that the performance of OEE in ESEC is better than the CANON after the implementation of TPM. The analysis also showed that out of the three TPM practices deployed, planned maintenance of equipment by production and maintenance team played the biggest role in increasing the equipment effectiveness. In conclusion, this study provides insights the importance of implementing TPM in order to succeed in a highly demanding market arena.
Students’ Explanation: Wider Variety of Teaching Methods Increases Motivation and Give Higher Results in Biology

By planning and teaching a specific topic, in an Upper Secondary School biology course in a highly formative way the effect on student learning was studied. Within given frames, students planned working methods and examination form within the topic of Gene technology. For the examination students also phrased learning goals and assessment criteria. The design resulted in higher summative grades on the topic compared to traditionally taught topics within the same course. In this study, students were interviewed in focus groups, one year after graduation to investigate student view on the intervention. One important outcome is that students appreciate variation in teaching more than the content itself. There was also a positive reaction to students planning working methods, but students wanted the teacher to perform different kinds of controlling actions. Findings are discussed in the context of formative methods with intentions of improving practical teaching methods.
Error Prediction for SINS/GPS after GPS Outage Based on Hybrid KF-UKF

The performance of MEMS-SINS/GPS integrated system degrades evidently during GPS outage due to the poor error characteristics of low-cost IMU sensors. The normal EKF is unable to estimate SINS error accurately after GPS outage owing to the large nonlinear error caused by MEMS-IMU. Aiming to solve this problem, a hybrid KF-UKF algorithm for real-time SINS/GPS integration is presented in this paper. The linear and nonlinear SINS error models are discussed, respectively. When GPS works well, we fuse SINS and GPS with KF with linear SINS error model using normal EKF. In the case of GPS outage, we implement Unscented Transform to predict SINS error covariance with nonlinear SINS error model until GPS signal recovers. In the simulation test that we designed, an evident accuracy improvement in attitude and velocity could be noticed compared to the normal EKF method after the GPS signal recovered.
No Evidence for Significant Age Spreads in Young Massive LMC Clusters

Recent discoveries have put the picture of stellar clusters being simple stellar populations into question. In particular, the color-magnitude diagrams of intermediate age (1-2 Gyr) massive clusters in the Large Magellanic Cloud (LMC) show features that could be interpreted as age spreads of 100-500 Myr. If multiple generations of stars are present in these clusters then, as a consequence, young (<1 Gyr) clusters with similar properties should have age spreads of the same order. In this paper we use archival Hubble Space Telescope (HST) data of eight young massive LMC clusters (NGC 1831, NGC 1847, NGC 1850, NGC 2004, NGC 2100, NGC 2136, NGC 2157 and NGC 2249) to test this hypothesis. We analyzed the color-magnitude diagrams of these clusters and fitted their star formation history to derive upper limits of potential age spreads. We find that none of the clusters analyzed in this work shows evidence for an extended star formation history that would be consistent with the age spreads proposed for intermediate age LMC clusters. Tests with artificial single age clusters show that the fitted age dispersion of the youngest clusters is consistent with spreads that are purely induced by photometric errors. As an additional result we determined a new age of NGC 1850 of ~100 Myr, significantly higher than the commonly used value of about 30 Myr, although consistent with early HST estimates.
Somatic cell count and milk yield losses in goats.

HANUŠ OTO, ROUBAL PETR, KUČERA JOSEF, KLIMEŠOVÁ MARCELA, JEDELSKÁ RADOSLAVA, KOPECKÝ JAROSLAV. 2017. Somatic Cell Count and Milk Yield Losses in Goats. Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 65(4): 1149–1160. This work is aimed at prediction and quantification of goat milk yield (MY, kg) losses by the somatic cell count (SCC, 103.ml−1) in milk recording. The goal is to support the prevention of milk secretion disorders, milk yield and quality. During two years there were evaluated composition and properties of individual milk samples (n = 1 173). There were included animals of brown short‐haired (BSH) breed and BSH × white short‐haired in one flock. The linear and nonlinear regression, interpolation, extrapolation, approximation and qualified estimation were used for milk losses prediction along the SCC. The relevant values of the SCC arithmetic and geometric mean and median and MY arithmetic mean were: 1,400 103.ml−1 (with high variability of 128 %), 745 and 747 103.ml−1; 2.94 kg/ day. The relationship between fat and crude protein had a correlation coefficient of 0.395, P < 0.001. There were stated the correlations between SCC and: lactose −0.416, P < 0.001; solids non fat −0.25, P < 0.001; MY −0.135, P < 0.01. The relationship between SCC and MY was negative along months, 6 cases out of 7 and significant in March and May (P < 0.05 and P < 0.01). For instance predicted MY for SCC intervals 1–1.999, 2–2.999, 3–3.999, 4–4.999, 5–5.999, 6–6.999 and ≥ 7 thousands 103.ml−1 may be 3.99, 3.77, 3.6 , 3.46, 3.33, 3.23 and 3.13 kg in 3rd month etc. The corresponding MY losses by SCC are evident from this trend. The result use is focused on the original dairy goat farm and use elsewhere is possible in farms with similar SCC, goat milk yield and rearing system.
The Performance of Music and Speech with Different Frequency Lowering Devices

Objective: Previous research studies have documented the benefits of both frequency transposition (FT) and non-linear frequency compression (NLFC) for patients with different degrees of hearing loss, however, very few studies directly compare the effect of two different frequency lowering (FL) techniques on the same population to investigate if superior performance in terms of speech and music perception exists. Design and Sample: The aim of the study was to determine whether people with a moderate to severe hearing loss have improved music perception and speech intelligibility with the use of FL and if the benefits is dependent on a specific FL strategy. A parallel research design was implemented and a purposive sampling method was used. Participants (n=20) were experienced hearing aid users with bilateral, moderate to severe hearing losses and no FL experience. A music perception questionnaire were completed by participants to rate their perception of music and the Music Perception Test (MPT) were used to assess participants’ musical performance. The Phoneme Perception Test (PPT) and Hearing-in-Noise Test (HINT) were used to assess participants’ speech perception abilities. Two commercial hearing aid devices with different FL approaches (FT and NLFC) were used. Results and Conclusion: Results indicate that participants distinguish high frequency sounds better with both FL strategies than without it resulting in better speech intelligibility in quiet and in noise. Greater speech scores with NLFC compared to FT was evident. Participants that used FT showed more confusion regarding speech perception. In terms of music perception the study shows that NLFC improves participants’ pitch and melody perception whereas mostly no musical improvement was observed with FT. With the use of FT participants’ ability to identify melodies decreased. A strong preference to listen to classical music with NLFC compared to FT was noted. Therefore it is evident that FL can improve speech and music perception for people with moderate to severe hearing losses but the perceived benefit seems to be dependent on the specific FL strategy implemented.
Utilising the zebrafish model organism to study the effect of FLCN in early embryonic development and Genotyping and platelet phenotyping of cases of rare inherited platelet based bleeding disorders

Birt-Hogg-Dube syndrome (BHD) (OMIM: #135150) is a rare genodermatosis following a dominant pattern of inheritance. The heritable genetic cause of BHD has been determined as mutations within the gene Folliculin (FLCN). A variable phenotype has been observed in systems modelling loss of function of FLCN, this study therefore intends to take a novel approach to mutational studies by utilising the zebrafish model organism. We exploit the optical benefits of the zebrafish model using imaging analysis of a Fucci transgenic line and in situ hybridisation and are able to suggest a possible functional role of FLCN within cell cycle regulation and morphogenesis in the developing brain. Platelet based bleeding disorders are a rare subset of bleeding diathesis that can incorporate thrombocytopenias and platelet function defects. Both thrombocytopenias and platelet function defects present clinically with symptoms relating to hypocoagulability that often manifest as a variation of bleeding episodes. To date there is a large collection of inherited platelet based bleeding disorders incorporating a spectrum of genes with an elucidated role in platelet development or function. This study aims to progress work in this field by using a whole exome sequencing approach following the Genotyping and Platelet Phenotyping (GAPP) protocol. We focus our efforts on two patients families and determine novel candidate variations as potentially disease causing. These candidate variations offer a starting point for subsequent research which can help produce a novel diagnosis and determine new genes with an involvement in platelet functioning and development.
