Book review: The future of capitalism: facing the new anxieties by Paul Collier

In The Future of Capitalism: Facing the New Anxieties, Paul Collier offers a forthright discussion of capitalism today that seeks to diagnosis and propose remedies for the anxieties shaping divisions between families, cities and nations. Staying away from clichés, ideology or populism, Collier calls our attention to pragmatism and the ‘hard centre’, and he is impressive in doing so in this notable book, writes Mehmet Emin Bayram

Baskı devre kartı dizgi atölyelerinde hat dengeleme

In assembling printed circuit boards (PCB), the use of numerically or computer controlled electronic component placement machines has become quite popular in the last decades. However, serious operations research problems arise through their use such as, allocation of component types to machines, board production schedule, feeder configuration and placement sequencing. In this study, the problem of allocation of component types to machines is taken up where two non-identical machines are deployed serially on a line to complete the assembly process of PCBs. For the solution of this problem three heuristic algorithms are suggested and their performances are investigated on experimental data.Son yıllarda baskı devre kartlarının (BDK) dizgisinde nümerik veya bilgisayar kontrollü elektronik dizgi makinalarının kullanımı yaygın hale gelmiştir. Ancak, bu beraberinde komponent tiplerinin makinalara atanması, kart üretim çizelgelemesi, besleyici düzeni ve dizgi sırası gibi karmaşık yöneylem araştırması problemlerini getirmiştir. Bu çalışmada, birbirinden farklı iki makinanın aynı hatta olması durumu için komponentlerin makinalara atanması problemi ele alınmıştır. Bu problemin çözümü için üç ayrı sezgisel algoritma geliştirilmiş ve performansları örnek veriler üzerinde incelenmiştir

Seismic Displacement Demand of a Mid-Rise RC Building Considering Soil Structure Interaction

This study aims to evaluate the effect of soil structure interaction and the differences in linear and nonlinear modelling of the structure on seismic response. For this purpose, SSI and fixed base models of 7-story building were used. Both linear and nonlinear behavior of the building are taken into account for comparison. The findings obviously indicate large variation in displacement demands depending on ground motion record, soil type, consideration of soil structure interaction and linear and nonlinear structure modelling. The displacement demands tend to increase for softer soils except few cases, especially for fixed base models. Significant differences are obvious for linear and nonlinear building models of fixed base case. The evaluation of obtained results and observations in the current study clearly indicate that the effects of SSI approach depend on dynamic characteristics of soil and structure. While soil deformations influence the seismic demands of structure in positive way for linear models, these effects are more complex for nonlinear models. It is difficult to mention about certain trend for nonlinear models. It should be also kept in mind that linear fixed base models are inappropriate for dynamic analysis due to high sensitivity of dynamic amplification and the use of fixed base linear models may cause inaccurate seismic demand estimates. The outcomes and observations emphasize that the demand estimates are independent from the fixed base or SSI approaches and linear or nonlinear models for stiffer soils. All combinations provide reasonable demand estimates. However, the modelling approach becomes extremely important for softer soils. The best approach seems to be SSI with nonlinear modelling. The fixed base with nonlinear modelling also provides acceptable estimates

Golden maps between Golden Riemannian manifolds and constancy of certain maps

We first introduce Golden maps between Golden Riemannian manifolds, give an example and show that such map is harmonic. Then we investigate the constancy of certain maps from Golden Riemannian manifolds to various manifolds by imposing the holomorphic-like map condition. Then we consider the reverse case and show that all such maps are constant

Investigation of the interaction between milk urea nitrogen (MUN) and some parameters in determining the level of nutrition in dairy cows

This study was carried out to determine the relationship between the amount of Milk Urea Nitrogen (MUN) and nutritional level in dairy cows. The research material was milk samples which were collected from 100 different commercial dairy farms. Three groups were assigned according to the milk analysis in the experiment. Group A, those having normal MUN values between 12-16 mg / dl in milk samples, group B, those having less MUN value and group C, those having high MUN value. Apart from this acetone, Beta hydroxy butyric acid (BHBA), total solid matter, fat, fat-free dry matter, crude protein (CP),true protein (TP), lactose, saturated fatty acids (SFA), total unsaturated fatty acids (TUFA), Polyunsaturated fatty acid (PUFA), Monounsaturated fatty acid (MUFA) and aflatoxin M1 values measured in milk and these were compared with low, normal and high MUN levels. In the study the MUN values of the groups were 14.46, 10.05 and 20.15 mg / dl respectively. At the end of the study, although the differences between the groups' acetone values were statistically significant (P <0.05), the values of all three groups were among the normal acetone values determined for dairy cows. Moreover, there were differences in milk regarding BHBA, fat, CP,TP, SFA, MUFA and AFM1 values (P<0.01) between the groups. As a concluded that some further detailed studies are required to get to know a deeper understanding of MUN levels in milk cows between acetone, BHBA and other parameters and metabolic diseases.Bu araştırma, süt ineklerinde süt üre azotu miktarı ile beslenme düzeyi arasındaki ilişkinin belirlenmesi amacıyla gerçekleştirilmiştir. Araştırmanın materyalini 100 farklı süt ineği işletmesinden toplanan süt numuneleri oluşturmuştur. Araştırmada sütte yapılan analizlere göre 3 grup oluşturulmuştur. Alınan süt numunelerinde MUN değerleri 12-16 mg/dl arasında olanlar normal (grup A) bu değerin altında olanlar düşük (grup B) üzerinde olanlar ise yüksek (grup C) olarak kabul edilmiştir. Ayrıca sütte ölçülen aseton ve beta hidroksi bütirik asit (BHBA) değerlerinin yanı sıra toplam katı madde, yağ, yağsız kuru madde, ham protein, gerçek protein, laktoz, doymuş yağ asidi, toplam doymamış yağ asitleri (TUS), çoklu doymamış yağ asitleri (PUFA), tekli doymamış yağ asitleri (MUFA) ve aflatoksin M1 seviyelerine göre düşük, normal ve yüksek üre azotu değerleri ile karşılaştırılmıştır. Araştırmada, grupların MUN değerleri sırasıyla: 14.46, 10.05 ve 20.15 mg/dl’dir. Araştırma sonunda grupların aseton değerleri arasındaki farklılıklar istatistik olarak anlamlı olmasına (P<0.05) rağmen her üç grubun değerleri de süt inekleri için belirlenen normal aseton değerleri arasındadır. Benzer şekilde sütte BHBA, yağ, ham protein, gerçek protein, doymuş yağ asitleri, MUFA ve AFM1 değerleri açısından gruplar arasında anlamlı farklılıklar bulunmaktadır (P<0.01). Sonuç olarak süt ineklerinde MUN değeri, aseton, BHBA ve diğer parametreler ile metabolik hastalıklar arasındaki ilişkileri anlamak için daha ayrıntılı çalışmalara ihtiyaç bulunmaktadır.Afyon Kocatepe Üniversitesi,Bilimsel Araştırma Projeleri Komisyonu, (AKÜ- BAPK-Proje No: 14.SAĞBİL.17

Objective: The aim of this retrospective study was to determinethe frequency rates of Giardia and E.histolytica/E.dispar and their distribution by years as well as agegroups and gender distribution during a four-year period.Materials and methods: A total of 9911 stool samplessent to our laboratory between January 2008 and December2011 were tested for parasites. Native-Lugol and formolethyl acetate sedimentation methods were utilized formicroscopic identification of Entamoeba sp. and Giardiatrophozoites and cysts in fresh stool samples. Additionally,trichrome staining was performed in stool sampleswhere the distinctive diagnosis could not be confirmed.Results: From a total of 9911 stool samples analyzedduring the study, 4.7% were positive for Giardia and 6.2%were positive for Entemoeba histolytica/ Entemoeba dispar.Of Giardia-positive patients 57% were male and 43%female. Similarly, 56% of Entemoeba histolytica/ Entemoebadispar positive patients were male and 44% werefemale. Both parasites’ higher frequency rates seen inmale groups were found statistically significant (p<0.01).Conclusion: It is seen that intestinal protozoon infectionsare still present as an important public health problemin our region. In order to prevent this problem, personalhygiene and sanitation rules education for community aswell as infrastructure improvements are necessary.Key words: Giardia, Entemoeba histolytica/ Entemoeba dispar, prevalenc
