The Influence of Microbiological Quality of Water Resources in Dairy Goat Farms
Authors: Iancu Ramona Maria 
Published: August 2015

Abstract
Water pollution is an essential component for the farmers in managing their agriculture fams. In almost all cases, without the chemical and microbiological analysis of water samples, the effect is damaging the animals and also the consumers. The study was carried out in Sibiu region of Romania, along Hârtibaciu River, and includes four farms, averaging 250 goats with different production system. Difficulties in ensuring quality milk, derived from various sources of contamination, the quality of water is directly depended on the maintenance of water suply. The foreign substances or microorganisms sometimes don’t affect the appearance or taste of the water, but can influence the health of animals and of course the quality of dairy products. This study was made to analyse the microbiological quality of water resources of the farmers, knowing that this is a major factor which influence the guality of the milk. The bacteriological tests were made onto Agar medium culture in petri dishes and were incubated at 37°C for 48h. Based on the microbiologicaly tests of the Hârtibaciu River resource, we could analyse the quality of the milk, too. The results of this study was presented and discused with the farmers and it was the starting point for them in changing their breeding technology, looking forward to improve their dairy production. A better quality of goat milk will be the main purpose of this study knowing that the farmers successed in their business
The Influence of Storage Time on the Yield of Alcohol Extraction from Marc
Authors: Balteş Mihaela 
Published: August 2015

Abstract
The influence of time on the yield of alcohol extraction from marc stored monitored and interpreted for 10, respectively 20, 40, 60 and 80 days was investigated. The distillation of diffusion juice obtained through two fermentation variants led to the conclusion that a longer storage time leads to a drastic decrease of the alcohol level in marc. Thus, this valuable sub product evaporates, i.e. is lost. It was clear that the results were strongly connected, although the procedure differs from the point of view of the order of the technological succession.

Authors: Baino Francesco , Vitale-Brovarone Chiara 
Published: August 2015

AbstractIn the last few years, optimal fixation of orthopaedic implants evolved to preserve host bone and enhance tissue integration by surface modifications, including the use of coatings with bioactive ceramics. In this work, we fabricated a novel bone-like porous bioactive glass-ceramic coating on curved alumina substrates; good joining between the two components was possible due to the interposition of a glass-derived dense interlayer. The mechanical properties of the porous glass-ceramic, which mimics the 3-D pore architecture of cancellous bone, are adequate for load-bearing applications (compressive strength of 19 MPa and fracture energy around 6.5×10

Published: August 2015

AbstractPhosphate glasses are novel amorphous biomaterials due to their fully resorbable characteristics, with controllable degradation profiles. In this study, phosphate glasses containing titanium and/or iron were identified to exhibit sufficiently matched thermal properties (glass transition temperature, thermal expansion coefficient and viscosity) which enabled successful co-extrusion of glass billets to form a core/clad preform. The cladding composition for the core/clad preforms were also reversed. Fe clad and Ti clad fibres were successfully drawn with an average diameter of between 30~50 μm. The average cladding annular thickness was estimated to be less than 2 μm. Annealed core/clad fibres were degraded in PBS for a period of 27 days. The strength of the Fe clad fibres appeared to increase from 303 ± 73 MPa to 386 ± 45 MPa after nearly 2 weeks in the dissolution medium (phosphate buffered solution) before decreasing by day 27. The strength of the Ti clad fibres revealed an increase from 236 ± 53 MPa to 295 ± 61 MPa when compared at week 3. The tensile modulus measured for both core/clad fibres ranged between 51 GPa to 60 GPa. During the dissolution study, Fe clad fibres showed a peeling mechanism compared to the Ti clad fibres.
An investigation into a contactless photoplethysmographic mobile application to record heart rate post-exercise: Implications for field testing
Authors: Peart Daniel J. , Shaw Matthew P. , Rowley Chris G. 
Published: August 2015

Summary
Study aim: the aim of this study was to compare the accuracy of a contactless photoplethysmographic mobile application (CPA) to record post-exercise heart rate and estimate maximal aerobic capacity after the Queen’s College Step Test. It was hypothesised that the CPA may present a cost effective heart rate measurement tool for educators and practitioners with limited access to specialised laboratory equipment.

Materials and Methods: seventeen participants (eleven males and six females, 28 ± 9 years, 75.5 ± 15.5 kg, 173.6 ± 9.8 cm) had their heart rate measured immediately after the 3-min test simultaneously using the CPA, a wireless heart rate monitor (HRM) and manually via palpation of the radial artery (MAN).

Results: both the CPA and MAN measurements had high variance compared to the HRM (CV = 31 and 11% respectively, ES = 1.79 and 0.65 respectively), and there were no significant correlations between the methods. Maximal oxygen consumption was estimated 17% higher in CPA compared to HRM (p < 0.001).

Conclusions: in conclusion it is recommended that field practitioners should exercise caution and assess the accuracy of new freely available technologies if they are to be used in practice.
A Genealogy of State Sovereignty
Authors: Zucca Lorenzo 
Published: August 2015

AbstractA genealogical account of state sovereignty explores the ways in which the concept has emerged, evolved, and is in decline today. Sovereignty has a theological foundation, and is deeply bound up with the idea of God, in particular a voluntarist God, presented as being capable of intervening directly in the world. Religious conflicts in the sixteenth and seventeenth centuries forced the separation between religion and politics, and opened the space for the emergence of a national state endowed with sovereignty which has dominated the world until now. Today’s rise of international and transnational obligations challenges the conventional understanding of state sovereignty, which cannot account for the normative density of the global order and the corresponding decline of state-based political authority. In order to explain that, I contrast two competing understandings of state sovereignty: a static one and a dynamic one. The static understanding regards sovereignty as absolute within the state territory. The dynamic understanding regards sovereignty as evolutionary: according to this account, the state is just one possible form that sovereignty can take. I conclude by suggesting that the dynamic understanding of state sovereignty is better suited to explaining the decline of state sovereignty.
Establishment of Agrobacterium tumefaciensmediated transformation system for Phomopsis asparagi, the pathogen of asparagus stem blight / Asparagus (Kuşkonmaz) pas hastalığına neden olan Phomopsis asparagi için Agrobacterium tumefaciens’e dayalı transformasyon sistemi geliştirilmesi

Abstract
Objective: The transformation system for the asparagus stem blight pathogen Phomopsis asparagi (Sacc.) Bubak has not yet been reported. In the present study, we intend to achieve and optimize the genetic transformation of P. asparagi. This study aims at establishing the foundation for understanding the pathogenic mechanism of P. asparagi, which will be of great theoretical and practical significance.
Methods: The Agrobacterium tumefaciens-mediated transformation (ATMT) system for P. asparagi was constructed at three aspects, i.e. condition optimization, insertion verification and transformant stability.
Results: The optimal conditions for this ATMT system were as follows: 8 h of pre-induction, 48 h of co-culture, 200 μmol/L AS in ISM, co-culture at 25-28°C and pH 5.6-5.8 of ISM at the co-culture phase. The PCR result of the hph gene revealed that an expected band of about 500 bp was amplified from all the 10 transformants selected at random, and the PCR result of the Vir gene revealed that an expected band of about 730 bp was amplified from the four strains of A. tumefacien as positive controls, whereas no corresponding DNA band could be amplified from the 10 transformants. The results of the two PCR amplifications clearly showed that T-DNA was indeed inserted into the genome of target isolate FJ2. The stability result revealed that transformants still displayed high resistance to hygromycin B and could grow normally after subculture for five generations.
Conclusion: A stable and efficient ATMT transformation system for P. asparagus was constructed systematically, in which a high transformation rate was achieved. For improving this system, the trasformation conditions were optimized through gradient experiments, T-DNA insertion was verified through dual PCR and the insertion segment containing hph gene in the transformant was proved hereditary stable through subculture. This system layed a foundation for the research on pathogenic mechanism and pathogenicity-related genes of P. asparagi.
Sudden Death in Hemodialysis Patients
Authors: Cohle SD , Graham MA 
Published: August 2015

Abstract
Hemodialysis patients may die suddenly and unexpectedly from a number of causes. These may be divided into those deaths due directly to and occurring during hemodialysis, those deaths occurring while the patient is not undergoing dialysis, and those deaths that may occur at any time. The first group includes brain herniation, air embolism, acute hemorrhage as a result of machine malfunction or fistula rupture, electrocution, cardiac arrhythmia caused by hypokalemia, complications of subclavian intravenous catheter insertion, third-degree heart block as a result of triglyceride emulsion, and disseminated intravascular coagulation (DIC) or hyperkalemia caused by overheated dialysate. The second group includes deaths due to pericardial tamponade because of effusion and suicidal causes of death (exsanguination, electrolyte imbalance as a result of excessive intake of salt, fluid, or potassium) as well as more conventional methods of suicide. The last category includes people dying of arteriosclerotic cardiovascular disease, hypertensive cardiovascular disease, and internal hemorrhage. Investigation of these deaths, including pertinent historical, laboratory, and autopsy data and investigation of dialysis equipment, is discussed.
Blood Alcohol Concentration Determined from Urine Samples as a Practical Equivalent or Alternative to Blood and Breath Alcohol Tests
Authors: Biasotti AA , Valentine TE 
Published: August 2015

Abstract
The value of urine tests for determining an equivalent blood alcohol concentration in driving under the influence (DUI) enforcement cases is reviewed from a historical, theoretical, and practical perspective. The limits of precision and accuracy that can be ascribed to urine alcohol results are demonstrated through an evaluation of actual case results wherein both a first void and a subsequent urine sample were analyzed and converted to an equivalent blood alcohol concentration (BAC) using a urine to blood conversion factor of 1.3:1.
Stab Wounds and Personal Identity Determined from Skeletal Remains: A Case from Kansas
Authors: Frayer DW , Bridgens JG 
Published: August 2015

Abstract
Evidence for cause of death in skeletonized remains is uncommonly found and cases that involve stabbings are particularly rare. In the following report, evidence is presented for a fatal stabbing, determined from analysis of a recent homicide. Because multiple stab wounds were present and several different bones were involved, estimates of the dimensions of the murder weapon were also possible. We also review some distinct vertebral anomalies used for personal identification.

Published: August 2015

Abstract
This book contains comprehensive information for analysis and evaluation of metals in human toxicology. After a short general discussion on absorption, metabolism, excretion, and dose-effect relationships, a more detailed chapter deals with biological effects and monitoring exposure to toxic metals. Firstly, principles of biological monitoring are discussed in the context of biochemical effects on animal systems. Then, indices for exposure are discussed in considerable detail for each of the nine most important toxic metals. Each is dealt with in the context of interpretation and the significance of monitoring in blood, urine, hair, or other specimens.
An In Vitro Study of the Accuracy and Precision of Breathalyzer® Models 900, 900A, and 1000
Authors: Caplan YH , Yohman DT , Schaefer JA 
Published: August 2015

Abstract
Ninety Breathalyzer® instruments (Model 1000) and twenty instruments (Models 900, 900A) were studied using a protocol described by the Department of Transportation's “Standard for Devices to Measure Breath Alcohol.” Although the mean of each of three concentrations tested (0.05, 0.10, and 0.15 g/210 L) compared favorably in both series, the standard deviation was consistently higher for the Model 1000 instruments. The Model 1000 instruments also produced a significant number of test results which exceeded the normally expected scientific deviation.
Osteometric Analysis of Sexual Dimorphism in the Sternal End of the Rib
Authors: İşcan YM 
Published: August 2015

AbstractAlthough there have been a number of radiological studies of the entire anterior thorax, no attempt has been made to establish a method of sex determination based on direct metrical analysis of an isolated rib. The present study attempts to determine sex from the sternal end of the fourth rib. The sample (144 males, 86 females) was obtained from individuals of known age, sex, and race autopsied at a medical examiner's office. Three measurements (height, width, and sternal articular pit depth) were taken from each bone. The sample was divided into three groups: young, old, and the combined total and analyzed by means of stepwise discriminant function statistics. It was found that the accuracy of sex determination varied from 82% in the young and 89% in the old groups to 83% for the combined group. However, when a discriminant function formula developed for a different age group was used the accuracy of correct assessment diminished considerably. It was, therefore, concluded that sexual dimorphism can be detected by metrical analysis from the teens to the 70s and this dimorphism increases with age.
In Vivo Measurements of Facial Tissue Thicknesses in American Caucasoid Children
Authors: Hodson G , Lieberman LS , Wright P 
Published: August 2015

Abstract
Ultrasonic determinations were made of facial tissue thicknesses in 50 healthy American caucasoid children, ranging in age from 4 to 15. Twenty measurements were taken at sites along the median, right sagittal, and right lateral planes. A static scanner was used in the B-mode. Three measurements significantly increased with age, the mid-philtrum (rs = 0.43, p &lt; 0.01) in females, the mental sulcus (rs = 0.30, p &lt; 0.05) in males, and the frontal eminence (rs = 0.32, p &lt; 0.05) in both sexes. Moreover, 25% of the measurements, while not statistically significant, decreased with increasing age. These data provide a basis for facial reproductions in caucasoid children.
Secreted Blood Group Substances: Distributions in Semen and Stabilities in Dried Semen Stains
Authors: Baechtel FS 
Published: August 2015

Abstract
A sensitive microplate hemagglutination-inhibition technique has been used to ascertain the distributions of secreted blood group substances (BGS) in a population of 176 semen specimens and to characterize the stability of these substances in dried semen stains. The BGS concentrations in semen were found to vary throughout a wide range of titer. Despite this latitude of variation, the titers for the component BGS within the blood groups could be described by a lognormal distribution function. Studies of a number of sequential semen specimens obtained from the same donors revealed that the intraindividual variation in BGS titers was much more limited than the interindividual BGS titers. Attempts to correlate variations in titers between A and H in Group A semen or B and H in Group B semen indicated that the levels of these component substances vary independently.
Studies of the stability of BGS in Groups A and O semen suggested that these substances were stable when the semen stains were stored at −20°C, 4°C, or at ambient laboratory temperature in a dry state. In contrast, stains stored at 37°C under hunmid conditions suffered a dramatic loss in BGS titer, with the half-life of the BGS being on the order of 30 days.
Strut Fracture in a Bjork-Shiley Aortic Valve Prosthesis
Authors: Lifschultz BD , Donoghue ER 
Published: August 2015

Abstract
Strut fracture can be a life-threatening adverse effect of mechanical prosthetic heart valves. This complication has occurred in the DeBakey, the Beall, the Cooley-Cutter and, most recently, the Bjork-Shiley valves. We report the case of a 35-year-old man who died suddenly 16 months after a 60° Bjork-Shiley Convexo-Concave heart valve prosthesis was inserted in the aortic position. At autopsy, the two welded attachments of the valve's outlet strut had fractured. The valve's tilting disc was found in his abdominal aorta.
A Rare Suicidal Case of a Ten-Year-Old Child Stabbing Himself in the Throat
Authors: Hasekura H , Fukushima H , Yonemura I , Ota M 
Published: August 2015

Abstract
A rare case is reported of a ten-year-old boy who committed suicide by stabbing himself in the throat with a pointed knife. Possibility of an accidental injury was excluded by the autopsy findings; suspicion of a homicide by his father was cleared through the deposition of his sister. The reason of suicide was attributed directly to his father's severe scolding and indirectly to his mother's death two years before.

Abstract
The stated purpose of this book is to provide a “new approach to forensic handwriting identification theory” for the novice and experienced document analyst, trial counsel, and investigators. The “new” approach espoused by the author involves the use of set theory, calculus of probability, and the psychology of learning to provide the logical foundation for the three-part “house of truth” referred to in the text as the “tridium of handwriting identification.”
A Rapid Isolation Technique for Drugs from Tissues and Fluids: Use of the Du Pont Prep 1 System
Authors: Balkon J , Donnelly B , Prendes D 
Published: August 2015

AbstractA microprocessor-controlled, automated extraction/concentration device, the Prep 1 (Du Pont Clinical Systems), was evaluated for application to the isolation of drug substances from postmortem fluids and tissue homogenates. Two classes of materials were investigated: barbiturates and the benzodiazepine, diazepam. With as little as 200 mg of tissue, barbiturate derivatives were successfully isolated and measured by gas chromatography using nitrogen-phosphorus detection with a coefficient of variation of 2 to 5%. Diazepam was measured in a similar fashion with a coefficient of variation of 4.4%. Preliminary investigation indicates that this system is applicable to a wide range of drug substances of toxicological interest.
