How much should Hong Kong spend on its healthcare?
Authors: Yan Lam Angie Ho
Published: April 2018

Healthcare spending in Hong Kong has been the subject of much discussion in recent years. This article analyses the determinants of Hong Kong's optimal health spending, including the city's health status, its demographic and epidemiological profiles, the existing health input, and the allocation of government resources. Hong Kong's healthcare system suffers from underinvestment as reflected by insufficient manpower, inadequate medical resources, and technical and allocation inefficiency of the health input. An international comparison of healthcare spending also shows Hong Kong's total healthcare expenditure per capita is lower than the Organisation for Economic Co-operation and Development's average, leading to health inequities on the poor who have limited funds to pay for healthcare. Suggestions not only focused on the need to increase healthcare spending, but also promoted healthcare reform including health financing pooling, and the emphasis on disease prevention, primary care and a gatekeeping system.

Fitness-to-practise concerns and preventative strategies
Authors: Gallagher Ann , Zasada Magdalena , Jago Robert , Austin Zubin , Banks Sarah , Lucas Grace , Gaag Anna van der
Published: April 2018

Paramedicine is evolving into a graduate occupation underpinned by evidence-based practice and the development of professionalism. There is a disproportionate number of fitness-to-practise concerns against paramedics in the UK compared with other health professions, with the exception of medicine and dentistry. This article details findings from a Delphi process which invited expert responses to questions relating to concerns and preventative measures. The findings highlighted three levels of explanation: societal issues (public expectations and media attention); organisational issues (pressure on services and employer factors); and issues relating to individual paramedics. Preventative measures focused on input from employers, regulators, educators and registrants themselves and included: managing public expectations; more regulatory engagement; increasing organisational support; and changes to the selection and education of the workforce. A Delphi statement that reached 100% consensus pointed to the positive implications of reporting as it suggests increased awareness of avenues for raising concerns.
Comparison of the stability of three fixation techniques between porous metal acetabular components and augments
Authors: Beckmann N. A. , Bitsch R. G. , Gondan M. , Schonhoff M. , Jaeger S.
Published: April 2018

Objectives

In order to address acetabular defects, porous metal revision acetabular components and augments have been developed, which require fixation to each other. The fixation technique that results in the smallest relative movement between the components, as well as its influence on the primary stability with the host bone, have not previously been determined.

Methods

A total of 18 composite hemipelvises with a Paprosky IIB defect were implanted using a porous titanium 56 mm multihole acetabular component and 1 cm augment. Each acetabular component and augment was affixed to the bone using two screws, while the method of fixation between the acetabular component and augment varied for the three groups of six hemipelvises: group S, screw fixation only; group SC, screw plus cement fixation; group C, cement fixation only. The implanted hemipelvises were cyclically loaded to three different loading maxima (0.5 kN, 0.9 kN, and 1.8 kN).

Results

Screw fixation alone resulted in up to three times more movement (p = 0.006), especially when load was increased to 100% (p < 0.001), than with the other two fixation methods (C and SC). No significant difference was noted when a screw was added to the cement fixation. Increased load resulted in increased relative movement between the interfaces in all fixation methods (p < 0.001).

Conclusion

Cement fixation between a porous titanium acetabular component and augment is associated with less relative movement than screw fixation alone for all implant interfaces, particularly with increasing loads. Adding a screw to the cement fixation did not offer any significant advantage. These results also show that the stability of the tested acetabular component/augment interface affects the stability of the construct that is affixed to the bone. Cite this article: N. A.

High-fat/high-sucrose diet-induced obesity results in joint-specific development of osteoarthritis-like degeneration in a rat model
Authors: Collins K. H. , Hart D. A. , Seerattan R. A. , Reimer R. A. , Herzog W.
Published: April 2018

Objectives

Metabolic syndrome and low-grade systemic inflammation are associated with knee osteoarthritis (OA), but the relationships between these factors and OA in other synovial joints are unclear. The aim of this study was to determine if a high-fat/high-sucrose (HFS) diet results in OA-like joint damage in the shoulders, knees, and hips of rats after induction of obesity, and to identify potential joint-specific risks for OA-like changes.

Methods

A total of 16 male Sprague-Dawley rats were allocated to either the diet-induced obesity group (DIO, 40% fat, 45% sucrose, n = 9) or a chow control diet (n = 7) for 12 weeks. At sacrifice, histological assessments of the shoulder, hip, and knee joints were performed. Serum inflammatory mediators and body composition were also evaluated. The total Mankin score for each animal was assessed by adding together the individual Modified Mankin scores across all three joints. Linear regression modelling was conducted to evaluate predictive relationships between serum mediators and total joint damage.

Results

The HFS diet, in the absence of trauma, resulted in increased joint damage in the shoulder and knee joints of rats. Hip joint damage, however, was not significantly affected by DIO, consistent with findings in human studies. The total Mankin score was increased in DIO animals compared with the chow group, and was associated with percentage of body fat. Positive significant predictive relationships for total Mankin score were found between body fat and two serum mediators (interleukin 1 alpha (IL-1α) and vascular endothelial growth factor (VEGF)).

Conclusion

Systemic inflammatory alterations from DIO in this model system may result in a higher risk for development of knee, shoulder, and multi-joint damage with a HFS diet. Cite this article: K. H.

Residual heat during laser ablation of metals with bursts of ultra-short pulses
Authors: Jäggi Beat , Förster Daniel J. , Weber Rudolf , Neuenschwander Beat
Published: April 2018

The usage of pulse bursts allows increasing the throughput, which still represents a key factor for machining with ultra-short pulsed lasers. The influence of the number of pulses within a burst on the specific removal rate is investigated for copper and stainless steel. Furthermore, calorimetric measurements were performed to estimate the residual energy coefficient as well as the absorptance of machined surfaces for copper to explain the reduced specific removal rate for a 2-pulse burst and the similar or even higher rate for a 3-pulse burst compared to single pulse ablation. Based on the measurements, a description of the process using single pulses and pulse bursts with up to three pulses is presented.

Authors: Sahiti Arben , Ahmeti Skender , Ismajli Hysen
Published: April 2018

Unlike the other forms of investment strategies, foreign direct investment (FDI) involves the long-term commitment in the host country. FDI determinants are complex and multi-dimensional phenomena that result from both macro-economic and firm strategy considerations. The main objective of the present research is to review the empirical studies on FDI determinants in order to find out what motives international corporations are pursuing since the FDI policies and nation-specific business environment are directly affecting international corporations’ activity involvement. The literature and document review research method is adopted for this research, and the research is refined by including only papers that contained empirical studies on FDI determinants. Research has been carried out using secondary data drawn from a diverse pool of materials, including books, journals and other credible reports from international institutions. This research concludes the evidence of the mixed results on such a linkage.

Published: April 2018

Background:

The complete blood count (CBC) is used to evaluate health status in the contexts of various clinical situations such as anemia, infection, inflammation, trauma, malignancies, etc. To ensure safe clinical application of the CBC, reliable biological variation (BV) data are required. The study aim was to define the BVs of CBC parameters employing a strict protocol.

Methods:

Blood samples, drawn from 30 healthy subjects (17 females, 13 males) once weekly for 10 weeks, were analyzed using a Sysmex XN 3000 instrument. The data were assessed for normality, trends, outliers and variance homogeneity prior to coefficient of variation (CV)-analysis of variance (ANOVA). Sex-stratified within-subject (CVI) and between-subjects (CVG) BV estimates were determined for 21 CBC parameters.

Results:

For leukocyte parameters, with the exception of lymphocytes and basophils, significant differences were found between female/male CVIestimates. The mean values of all erythrocyte-, reticulocyte- and platelet parameters differed significantly between the sexes, except for mean corpuscular hemoglobin concentration, mean corpuscular volume and platelet numbers. Most CVIand CVGestimates appear to be lower than those previously published.

Conclusions:

Our study, based on a rigorous protocol, provides updated and more stringent BV estimates for CBC parameters. Sex stratification of data is necessary when exploring the significance of changes in consecutive results and when setting analytical performance specifications.
3D FDM production and mechanical behavior of polymeric sandwich specimens embedding classical and honeycomb cores
Authors: Brischetto Salvatore , Ferro Carlo Giovanni , Torre Roberto , Maggiore Paolo
Published: April 2018

Desktop 3D FDM (Fused Deposition Modelling) printers are usually employed for the production of nonstructural objects. In recent years, the present authors tried to use this technology also to produce structural elements employed in the construction of small UAVs (Unmanned Aerial Vehicles). Mechanical stresses are not excessive for small multirotor UAVs. Therefore, the FDM technique combined with polymers, such as the ABS (Acrylonitrile Butadiene Styrene) and the PLA(Poly Lactic Acid), can be successfully employed to produce structural components. The present new work is devoted to the production and preliminary structural analysis of sandwich configurations. These new lamination schemes could lead to an important weight reduction without significant decreases of mechanical properties. Therefore, it could be possible, for the designed application (e.g., a multifunctional small UAV produced via FDM), to have stiffener and lighter structures easy to be manufactured with a low-cost 3D printer. The new sandwich specimens here proposed are PLA sandwich specimens embedding a PLA honeycomb core produced by means of the same extruder, multilayered specimens with ABS external layers and an internal homogeneous PLA core using different extruders for the two materials, sandwich specimens with external ABS skins and an internal PLA honeycomb core using different extruders for the two materials, and sandwich specimens where two different extruders have been employed for PLA material used for skins and for the internal honeycomb core. For all the proposed configurations, a detailed description of the production activity is given.Moreover, several preliminary results about three-point bending tests, different mechanical behaviors and relative delamination problems for each sandwich configuration will be discussed in depth.
On Extended Quadratic Hazard Rate Distribution: Development, Properties, Characterizations and Applications
Authors: Bhatti Fiaz Ahmad , Hamedani G. G. , Sheng Wenhui , Ahmad Munir
Published: April 2018

In this paper, we propose a flexible extended quadratic hazard rate (EQHR) distribution with increasing, decreasing, bathtub and upside-down bathtub hazard rate function. The EQHR density is arc, right-skewed and symmetrical shaped. This distribution is also obtained from compounding mixture distributions. Stochastic orderings, descriptive measures on the basis of quantiles, order statistics and reliability measures are theoretically established. Characterizations of the EQHR distribution are studied via different techniques. Parameters of the EQHR distribution are estimated using the maximum likelihood method. Goodness of fit of this distribution through different methods is studied.
Discretization and Approximation of Surfaces Using Varifolds
Authors: Buet Blanche , Leonardi Gian Paolo , Masnou Simon
Published: April 2018

We present some recent results on the possibility of extending the theory of varifolds to the realm of discrete surfaces of any dimension and codimension, for which robust notions of approximate curvatures, also allowing for singularities, can be defined. This framework has applications to discrete and computational geometry, as well as to geometric variational problems in discrete settings. We finally show some numerical tests on point clouds that support and confirm our theoretical findings.

Published: April 2018

2010 年 5 月《全球華語詞典》 及 2015 年 4 月《全球華語大詞典》的相繼續出版，充分證明了當今世界性華語大家庭的真實存在。這兩本詞典的問世全面展示出當今全球華語詞彙集的總體共時面貌，同時也明白無誤顯示出各區域華語之間的詞語異同。

世界華語各大區域詞語的差異主要以中國大陸、中国台灣、中国港澳、新馬四大塊地域為其代表。其中中國大陸為當今華語的母體和主體，而中国台灣、中国港澳、新馬等地均為子體和異體。

世界華語區域詞語的差異成因主要源於下列三個方面：一是各區域存在著反映各自不同的社會制度、政經面貌、歷史地理、人文習俗，以及當地特有的事物和物產等；二是某些地區有著數目和地位不同的外國語言、漢語方言和方言文化的影響；三是某些地區的部分華語詞語的詞義和詞用產生了在地性變異或變化。

目前相應的對策應該是：（1）詳盡地細緻地描寫並記錄全球華語大家庭的的詞彙概貌及其異同；（2）深入地分析並剖析它們之間的相同、相似、相異的程度和成因；（3）通過交流、教學和研討，增進各區域相互之間的理解與溝通；（4）逐步通過專家篩選和社會使用（約定俗成），推動相互的流通、吸收、協調和融合，逐步達成最大程度的共同化和一體化。
Not Just for Money. Crowdfunding a New Tool of Open Innovation to Support the Agro-Food Sector. Evidences on the Italian Market
Authors: Pronti Andrea , Pagliarino Elena
Published: April 2018

The aim of this paper is to explore Crowdfunding as a new form of Open Innovation for SMEs and family business in the Agri-Food sector which usually do not have the same skills and tools to operate with conventional own Crowdsourcing methods. The study first has analyzed the principal literature and data available on Crowdfunding and the Food industry in order to describe the state of the art in this subject. Afterwards the focus of the paper goes to the analysis of the Italian case. The study used a deep qualitative approach because of an important lack of data and information on this subject. Nine depth interviews to key informants of the sector have been carried out investigating the market players, the normative regulations, the businesses models and the evolution of Crowdfunding for the Agri-Food industry in Italy. The research finds that Crowdfunding for Agri-Food industry can be important for both its profitability and the development of the sector, but that nowadays the Italian market is still in its primordial phase. Crowdfunding is very suitable for SMEs business which represents the vast majority of the Agri-Food Italian market and the use of this instrument could be beneficial for it.
Ergodicity, Maximum Entropy Production, and Steepest Entropy Ascent in the Proofs of Onsager’s Reciprocal Relations
Authors: Benfenati Francesco , Beretta Gian Paolo
Published: April 2018

We show that to prove the Onsager relations using the microscopic time reversibility one necessarily has to make an ergodic hypothesis, or a hypothesis closely linked to that. This is true in all the proofs of the Onsager relations in the literature: from the original proof by Onsager, to more advanced proofs in the context of linear response theory and the theory of Markov processes, to the proof in the context of the kinetic theory of gases. The only three proofs that do not require any kind of ergodic hypothesis are based on additional hypotheses on the macroscopic evolution: Ziegler’s maximum entropy production principle (MEPP), the principle of time reversal invariance of the entropy production, or the steepest entropy ascent principle (SEAP).
Cleft extensions for quasi-entwining structures
Authors: Alonso Álvarez J. N. , Fernández Vilaboa J. M. , González Rodríguez R.
Published: April 2018

In this paper we introduce the notions of quasi-entwining structure and cleft extension for a quasi-entwining structure. We prove that if (A, C, ψ) is a quasi-entwining structure and the associated extension to the submagma of coinvariants AC
is cleft, there exists an isomorphism ωA
between AC
⊗ C and A. Moreover, we define two unital but not necessarily associative products on AC
⊗ C. For these structures we obtain the necessary and sufficient conditions to assure that ωA
is a magma isomorphism, giving some examples fulfilling these conditions.
Certain results on q-starlike and q-convex error functions
Authors: Ramachandran C. , Vanitha L. , Kanas Stanisłava
Published: April 2018

The error function occurs widely in multiple areas of mathematics, mathematical physics and natural sciences. There has been no work in this area for the past four decades. In this article, we estimate the coefficient bounds with q-difference operator for certain classes of the spirallike starlike and convex error function associated with convolution product using subordination as well as quasi-subordination. Though this concept is an untrodden path in the field of complex function theory, it will prove to be an encouraging future study for researchers on error function.

Modeling of electric and heat processes in spot resistance welding of cross-wire steel bars
Authors: Iatcheva Ilona , Darzhanova Denitsa , Manilova Marina
Published: April 2018

The aim of this work is the modeling of coupled electric and heat processes in a system for spot resistance welding of cross-wire reinforced steel bars. The real system geometry, dependences of material properties on the temperature, and changes of contact resistance and released power during the welding process have been taken into account in the study.

The 3D analysis of the coupled AC electric and transient thermal field distributions is carried out using the finite element method. The novel feature is that the processes are modeled for several successive time stages, corresponding to the change of contact area, related contact resistance, and reduction of the released power, occurring simultaneously with the creation of contact between the workpieces. The values of contact resistance and power changes have been determined on the basis of preliminary experimental and theoretical investigations.

The obtained results present the electric and temperature field distributions in the system. Special attention has been paid to the temperature evolution at specified observation points and lines in the contact area. The obtained information could be useful for clarification of the complicated nature of interrelated electric, thermal, mechanical, and physicochemical welding processes. Adequate modeling is also an opportunity for proper control and improvement of the system.
Three-dimensional atom localization via probe absorption in a cascade four-level atomic system
Authors: Zeng Wei , Deng Li , Chen Aixi
Published: April 2018

For an atomic system with cascade four-level type, a useful scheme about three-dimensional (3D) atom localization is proposed. In our scheme the atomic system is coherently controlled by using a radio-frequency field to couple with two-folded levels under the condition of the existence of probe absorption. Our results show that detecting precision of 3D atom localization may be obviously improved by properly adjusting the frequency detuning and strength of the radio-frequency driving field. So our scheme could be helpful to realize 3D atom localization with high-efficiency and high-precision . In the field of laser cooling or the atom nano-lithography, our studies provide potential applications.

Published: April 2018

The level of electromagnetic radiation (EMR) exposure increases day by day as natural consequences of technological developments. In recent years, the increasing use of cellular systems has made it necessary to measure and evaluate EMR originating from base stations. In this study, broadband and band selective electric field strength (E) measurements were taken at four different times in order to evaluate the change of short term E in Atakum district of Samsun, Turkey. The measurements were collected from 46 different locations using a SRM 3006 and a PMM 8053 EMR meter in a band from 100 kHz to 3 GHz, and the maximum E (Emax) and the average E (Eavg) were recorded. The highest values have been noticed in these measurements at 9.45 V/m and 17.53 V/m for Eavg and Emax respectively. Apart from these measurements, 24 hour long term E measurements were taken at a location where the highest value was observed and analyzed, to observe the change of Es during a day. At the end of the study, a tentative mathematical model that helps in computing the total E of the medium with 95% accuracy, was obtained.
Chemical and petrochemical industry
Authors: Staszak Katarzyna
Published: April 2018

The potential sources of various metals in chemical and petrochemical processes are discussed. Special emphasis is put on the catalysts used in the industry. Their main applications, compositions, especially metal contents are presented both for fresh and spent ones. The focus is on the main types of metals used in catalysts: the platinum-group metals, the rare-earth elements, and the variety of transition metals. The analysis suggested that chemical and petrochemical sectors can be considered as the secondary source of metals. Because the utilization of spent refinery catalysts for metal recovery is potentially viable, different methods were applied. The conventional approaches used in metal reclamation as hydrometallurgy and pyrometallurgy, as well as new methods include bioleaching, were described. Some industrial solutions for metal recovery from spent solution were also presented.

Background

Vancomycin is increasingly administrated by continuous infusion. But the treatment of patient in intensive care need restricted volume to prevent fluid overload. The aim of the study was to evaluate the physical and chemical stability of solutions of a high concentration of vancomycin hydrochloride in 5 % glucose or 0.9 % NaCl.

Methods

Eight syringes of 50 mL, containing 41.66 mg/mL of vancomycin hydrochloride four syringes in 5 % glucose and four in 0.9 % NaCl were prepared and stored at ambient temperature during 48 h. Immediately after preparation and during 48 h, vancomycin hydrochloride concentrations were measured by a high-performance liquid chromatography (HPLC). Spectrophotometric absorbance at different wavelengths, pH measurement and microscopic observations were also performed.

Results

All solutions were physico-chemically stable during the whole period storage at ambient temperature: no color change, turbidity, precipitation or opacity, no significant pH variations or optic densities were observed in the solutions. Any crystals were seen by microscopic analysis. Solutions are considered chemically stable as the lower limit of the 95 % unilateral confidence interval on the mean remained above 90 % of the initial concentration for at least 48 h.

Conclusions

Solutions of vancomycin hydrochloride 41.66 mg/mL in syringe of 5 % glucose or 0.9 % NaCl are physically and chemically stable for at least 48 h when stored in syringes at ambient temperature.

Published: April 2018

The most common complication of the chronic venous leg are ulcers and their frequency increases with age. Taking into consideration time and cost of treatment the ulcers are a serious medical and socioeconomic problem. Causal treatment concerns vein surgery, however, the recurrence risk up to 50% is observed. In the case of contraindications the conservative treatment is practiced. Topical treatment of ulcers is one of the methods of the conservative therapy. Methods of conservative treatment include general and local pharmacotherapy and compression therapy. Shall apply surgical skin grafting. Nowadays the standard therapy is more often completed by physical methods. Physical methods are not only the complement of the conventional treatment, but also a relevant factor referring to the effective treatment, especially as far as the minimum of contraindications is concerned. Electrotherapy, magnetic therapy, sonotherapy, etc. belong to this kind of methods.

The purpose of the paper is to present some methods of physical therapy in the treatment of leg ulcers. Based on the presented in the literature regiments, summarizes efficiency of magnetic therapy, high-voltage electrical stimulation and sonotherapy in the treatment of ulcers. The paper is a review of the current knowledge on the effects of therapeutic action of the above-mentioned methods. The results of the review indicate that magnetic therapy, electrostimulation of high-voltage and sonotherapy have the influence on the process of accelerating the healing of leg ulcers. It has been proved that treatment with low-frequency magnetic field indicates analgesic and anti-inflammatory, purifies wounds, accelerates the skin formation and finally leads to a complete epithelialization. After applying high voltage electrostimulation, can be observed a reduction in the amount of purulend secretions. High voltage electrostimulation (HVS) accelerates the skin formation and granulation process. After applying sonotherapy the uclers surface decreased. Therapy accelerated the process of clearing the wound of pus and the formation of granulation tissue.

Authors: Michalak Edyta , Zygmańska Magdalena
Published: April 2018

Introduction: The aim of the study was to determine the impact of systematic individual Nordic Walking training on physical performance in older men.

Material and methods: The study included 18 men (aged 52 to 73), divided into two groups. Group I (the experimental group) underwent an 8-week Nordic Walking training, while group II (the control group) did not perform any physical activity during the analyzed period. The level of physical exercise tolerance was assessed twice: at the beginning and after eight weeks of the study period using the Finnish walking test and the 30-minute walking test. The results were analyzed with the use of Statistica 10. software.

Results: The results of the initial Finnish walking test show that the average values of the Fitness Index, time of a 2-kilometer distance coverage and HR were similar in both study groups. After 8 weeks, a statistically significant improvement in exercise tolerance was observed in the experimental group. Aerobic endurance evaluated on the basis of the Fitness Index increased (p <0.01). A reduction in time of 2 kilometer distance coverage (p <0.01) was accompanied by a reduction (p <0.05) in the level of HR. In the men qualified to the control group, all of the tested parameters remained unchanged. Within the study group, after 8. weeks of training, a significant improvement was also noted in the distance covered during the 30-minute walking test (p <0.01).

Conclusions: Regular aerobic physical activity improves exercise tolerance in older men and may contribute to improving the comfort of their living.

Introduction: Osteoarthritis constitutes one of the main reasons fora lower quality of life among theelderly. The aim of the work was to analyse factors affecting functional skills in the group ofpatients with coxarthrosis.

Material and methods: The study was conducted on 50 patients with diagnosed coxarthrosis (M16.0). Patients were selected in purposive samplingand underwent one examination. The quality of life was assessed with the use of EQ-5D-3L instrument and 36-Item Short FormHealth Survey (SF-36). Pain intensity was evaluated with the use of the Visual Analogue Scale (VAS), the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)and the authors’ own questionnaire. The research was carried out at the Rehabilitation Ward of the 3rdMunicipal Hospital in Lodz. The results were analysed in six age groups: 50-55, 55-60, 60-65, 65-70, 70-75 and 75-80.

Results: Coxarthrosis was prevalent in the group of patients aged 75-80 (13 participants). Patients aged 50-55 subjectively assessed their quality of life at the highest level. Body mass index (BMI) did not affect the quality of life or pain intensity.

Conclusions: The quality of life of patients with coxarthrosis is related to age but it does not correlate with body mass.

Select geotechnical properties of a lime stabilized expansive soil amended with bagasse ash and coconut shell powder
Authors: James Jijo , Pandian P. Kasinatha
Published: April 2018

Lime stabilization has been and still is one of the most preferred methods for stabilization of expansive soils. However, in the recent times, utilization of solid waste materials in soil stabilization has gained prominence as an effective means to manage wastes generated from various sources. In this work, an attempt has been made to utilize waste materials from two sources as auxiliary additives to lime in the stabilization of an expansive soil. Bagasse ash (BA), a waste by-product from the sugar industry and Coconut shell powder (CSP), a processed waste obtained from left over coconut shells of oil extraction industry were used as auxiliary additives. An expansive soil obtained from a local field was subjected to chemical, mineral, microstructural and geotechnical characterization in the laboratory and stabilized using 3% lime. The waste materials were subjected to chemical, mineral and microstructural characterization. The stabilization process was amended with four different contents viz. 0.25%, 0.5%, 1% and 2% of BA and CSP separately and the effect of the amendment was studied on the unconfined compressive strength (UCS), plasticity, swell-shrink and microstructural characteristics of the expansive soil. The results of the study indicated that BA amendment of lime stabilization performed better than CSP in improving the UCS, plasticity, swell-shrink and microstructure of the lime stabilized expansive soil.

To that goal, 4 types of pavement specimen including internal defects were fabricated to exploit the results obtained by heating the specimens by natural light. The results showed that defects located down to a depth of 3 cm could be detected by infrared thermography NDT using the improved image processing method.
The building blocks of speech: spontaneity, pre-packaging and the genre structuring of university lectures
Authors: Blackwell James W. , White Peter R. R.
Published: April 2018

This paper considers issues related to the textual organization of university lectures and the degree to which they are comprised of conventionalized text-organizational schema or genre stagings. It utilizes a dataset of video recordings and transcripts of four social science lectures which were delivered by two lecturers at a university in Japan in 2003, and offers findings which demonstrate that lecturers draw on a range of ready-made genres of the type which have been described in the so-called Sydney school genre literature and combine these conventionalized genres into genre complexes, which appear not to be conventionally or predictably ordered. The paper also offers some insights into at least one aspect of the distinction between online (spontaneous/spoken) versus offline (prepared/written) language. Specifically, it shows that lectures, as instances of spoken, apparently extemporaneous language do, to a significant degree, rely on pre-fabricated and culturally recurrent textual arrangements which the speakers draw on as they spontaneously produce the current communicative event.
Lernen und Lernversagen

Vorspann

Moderne Kriege werden nicht nur auf dem Schlachtfeld, sondern auch in Fabriken und Bergwerken gewonnen. Diese Erfahrung machte die politische und militärische Führung des Deutschen Reichs zwischen 1914 und 1918, als die Seeblockade der britischen Marine Rohstoffimporte aus Übersee weitgehend unterband. Jonas Scherner geht am Beispiel der Beschaffung kriegswichtiger Metalle wie Kupfer und Zinn der Frage nach, wie Politiker, Ökonomen und Militärs im NS-Staat zwischen 1939 und 1945 mit diesem Problem umgingen, welche Lehren sie aus der Rohstoffbewirtschaftung im Ersten Weltkrieg zogen und was die „Metallmobilisierung“ über Politik und Strategie im nationalsozialistischen Deutschland verrät.
