AbstractBackgroundPortable energy dispersive X-ray fluorescence (pEDXRF) spectrometry analysis was applied for the characterisation of archaeological ceramic findings from three Neolithic sites in Serbia. Two dimension reduction techniques, principal component analysis (PCA) and scattering matrices-based dimension reduction were used to examine the possible classification of those findings, and to extract the most discriminant features.ResultsA decision-making procedure is proposed, whose goal is to classify unknown ceramic findings based on their elemental compositions derived by pEDXRF spectrometry. As a major part of decision-making procedure, the possibilities of two dimension reduction methods were tested. Scattering matrices-based dimension reduction was found to be the more efficient method for the purpose. Linear classifiers designed based on the desired output allowed for 7 of 8 unknown samples from the test set to be correctly classified.ConclusionsBased on the results, the conclusion is that despite the constraints typical of the applied analytical technique, the elemental composition can be considered as viable information in provenience studies. With a fully-developed procedure, ceramic artefacts can be classified based on their elemental composition and well-known provenance.

AbstractWith the recent addition of anti-angiogenic agents to cancer treatment, the angiogenesis regulators in platelets are gaining importance. Platelet factor 4 (PF-4/CXCL4) and Connective tissue activating peptide III (CTAP-III) are two platelet-associated chemokines that modulate tumor angiogenesis, inflammation within the tumor microenvironment, and in turn tumor growth. Here, we review the role of PF-4 and CTAP-III in the regulation of tumor angiogenesis; the results of clinical trial using recombinant PF-4 (rPF-4); and the use of PF-4 and CTAP-III as cancer biomarkers.

Abstract
We describe the preparation of [(100 − y)/4](SrO–BaO–2Nb2O5)–yP2O5 (SBNPy) glasses and glass-ceramics with the Sr0.5Ba0.5Nb2O6 (SBN50) phase, using a conventional process, and the analysis of the chemical stability of the materials in water. The SBNPy glasses and glass-ceramics consist of orthophosphate (Q0) and pyrophosphate (Q1) units with strongly delocalized P=O bonds. Because of the presence of these phosphate units, the glasses and glass-ceramics obtained in this study show no weight changes, even after exposure to water at 70 °C for 100 h. We hypothesize that the lack of phosphate chains within the glass network is responsible for the superior water stability.
City present in city past: Rafael Chirbes’ cartographic imaginary
Authors: Compitello Malcolm Alan 
Published: June 2013

Abstract
This article examines Rafael Chirbes’ 1994 novel Los disparos del cazador in relationship to important transformations of Madrid’s built environment from the 1940s to the middle of the 1990s. Using as a point of departure the groundbreaking work of the geographer David Harvey on the relationships between cultural production and urban process, this article offers a model for analysis that bridges the gap between the humanities and social sciences and in so doing offers a reading that demonstrates how Chirbes’ text weaves a message of resistance into the fabric of his novel about urban change.

Published: June 2013

This Policy Statement was retired July 2020.
With advances in antiretroviral therapy, most HIV-infected children survive into adulthood. Optimal health care for these youth includes a formal plan for the transition of care from primary and/or subspecialty pediatric/adolescent/family medicine health care providers (medical home) to adult health care provider(s). Successful transition involves the early engagement and participation of the youth and his or her family with the pediatric medical home and adult health care teams in developing a formal plan. Referring providers should have a written policy for the transfer of HIV-infected youth to adult care, which will guide in the development of an individualized plan for each youth. The plan should be introduced to the youth in early adolescence and modified as the youth approaches transition. Assessment of developmental milestones is important to define the readiness of the youth in assuming responsibility for his or her own care before initiating the transfer. Communication among all providers is essential and should include both personal contact and a written medical summary. Progress toward the transition should be tracked and, once completed, should be documented and assessed.

ABSTRACTWe conduct a comparative study mainly on two types of nc-Si based solar cell structures, a-Si/a-SiGe/nc-Si triple-junction and a-Si/nc-Si double-junction. We have attained comparable initial efficiency for the both solar cell structures, 10.8∼11.8% initial total area efficiency (85 - 95W over an area of 0.79 m2). For better compatibility to our installed manufacturing equipment, we deposit a-Si and a-SiGe component cells with the existing deposition machines. Only nc-Si bottom component cells are prepared in separate deposition machines tailored for nc-Si process. Material properties of nc-Si and TCO films are also studied by Raman spectra, SEM, and AFM.
Midwife-Led Units: A Place to Work, A Place to Give Birth
Authors: de Labrusse Claire , Kiger Alice 
Published: June 2013

BACKGROUND:With an estimated 120 midwife-led units (MLUs) and 15 years’ experience, the United Kingdom displays expertise in what ways women and professionals might benefit from MLUs. This study explored midwives’ satisfaction and skills for working in an MLU and a consultant unit (CU) and how these compared.METHODS:In this exploratory study, both quantitative and qualitative data were collected by anonymous questionnaire from 45 midwives in 2 Scottish maternity units (July 2007).RESULTS:Midwives working in the MLUs reported a higher level of job satisfaction than midwives working in the CU. Demographic characteristics of the 2 groups differed: MLU midwives were older, had been in practice longer, and had higher grade posts. Qualitative findings revealed some reasons midwives preferred working in the MLU with the emotional support they could give to women, and highlighted some negative predictors of midwives’ satisfaction. The questionnaire also explored the midwives’ practice: most agreed that the ability to avert and manage problems, work in a low-technology setting, and let labor be are necessary to work in these units.CONCLUSION:Our findings revealed midwives’ greater satisfaction from working in MLU compared to CU. We identified midwives’ opinions of specific skills to work in MLU, highlighting areas of importance for midwifery.

Published: June 2013

Focused Clinical Question: Periodontal disease is related to use of tobacco, particularly cigarettes. Cigarette smoking is the leading cause of preventable death in the United States, with 20% of annual deaths attributable to smoking‐related illness. How does motivating patients to quit smoking challenge periodontists and other providers to improve clinical management?Summary: Four patient cases from the author's (CED) clinical practice in behavioral medicine illustrate key points in management of two patients who were successful in quitting smoking and two who were unsuccessful quitting.Conclusion: These cases illustrate some of the characteristics of patients and factors that contribute to successful smoking cessation and provide examples and practical information for use in the dental office for helping patients with smoking cessation.
Is There Still a Place for Continuous Closed Irrigation in the Management of Periprosthetic Total Knee Infection?

Published: June 2013

In recent decades, many technical improvements have been achieved in the use of prosthetic joints, and the risk of infection has been greatly reduced, to current rates of 0.4-2.0% following primary knee replacement. However, the increasing rate of joint replacements being performed means that the absolute number of such infections remains significant and poses substantial costs to healthcare systems worldwide. Accordingly, further strategies to treat and prevent total joint infections should be investigated.Infections following knee replacements can compromise the function and durability of arthroplasty. When these infections occur during the immediate postoperative period, irrigation and debridement with component retention can be attempted to salvage the implant. This is an attractive, cheap, low-morbidity treatment for periprosthetic knee infection. However, the results published regarding this procedure are uneven; some studies report the eradication of prosthetic joint infection by debridement alone in 70-90% of cases but conversely, others have reported a high failure rate for this procedure, averaging 68% (61-82%). The difference could be attributed in part to the multiplicity of variables that may influence the success of the procedure. One such is that of treatment with a continuous irrigation system, which has the theoretical advantage of enabling the administration of antimicrobial agents, as well as the drainage of debris and blood clots.The objective of this study is to elucidate the overall efficacy of irrigation and debridement with prosthesis retention in infected total knee arthroplasty and to determine whether the addition of a continuous irrigation system influences this efficacy.
Management of Infection After Intramedullary Nailing of Long Bone Fractures: Treatment Protocols and Outcomes

Published: June 2013

Implant related sepsis is a relatively unusual complication of intra-medullary nail fixation of long bone fractures. Depending on the extent of infection, timing of diagnosis and progress of fracture union, different treatment strategies have been developed. The aim of this review article is to collect and analyze the existing evidence about the incidence and management of infection following IM nailing of long bone fractures and to recommend treatment algorithms that could be valuable in everyday clinical practice. After searching the P u b M e d /Medline databases, 1270 articles were found related to the topic during the last 20 years. The final review included 28 articles that fulfilled the inclusion criteria.
Only a few prospective studies exist to report on the management of infection following IM nailing of long-bone fractures. In general, stage I (early) infections only require antibiotic administration with/without debridement. Stage II (delayed) infections can be successfully treated with debridement, IM reaming, antibiotic nails, and administration of antibiotics. Infected non-unions are best treated with exchange nailing, antibiotic administration and when infection has been eradicated with graft implantation if it is needed. Debridement, exchange nailing and systemic administration of antibiotics is the best indication for stage III (late) infections, while stage III infected non-unions can successfully be treated with nail removal and Ilizarov frame, especially when large bone defects exist.
Evaluation of Selected Hydrogeological Parameters of Weathered Granite in the Strzegom Area (Lower Silesia)
Authors: Gorecka Joanna Maria , Marszałek Henryk 
Published: June 2013

Streszczenie
W artykule przedstawiono wykształcenie litologiczne, miąższości oraz charakterystykę parametrów hydroge­ologicznych zwietrzelin granitu strzegomskiego. Wyniki przeprowadzonych badań oprócz aspektu poznawczego mają również znaczenie utylitarne, m.in. przy pracach rozpoznawczych przed udostępnieniem kolejnych partii złóż granitów do eksploatacji. Badania parametrów filtracyjnych zwietrzelin przeprowadzono w rejonie kamie­niołomów zlokalizowanych w obszarze Wzgórz Strzegomskich.
W profilu zwietrzelin wydzielono dwie ich odmiany różniące się składem granulometrycznym, miąższością i właściwościami filtracyjnymi. W górnej części występują gliniaste pokrywy stokowe o stwierdzonej maksy­malnej miąższości 1,6 m, zawierające do 70% frakcji drobnej <0,063 mm. Poniżej występują zwietrzeliny ziarniste zawierające 30-60% frakcji żwirowej i kamienistej.
Określone w warunkach polowych wartości współczynnika przepuszczalności pionowej k utworów przypo­wierzchniowych, odpowiadających w większości górnej, gliniastej warstwie zwietrzelin, są niskie i zawierają się w przedziale od 0,23 do 6,19 m/d (średnio 1,6 m/d). Najniższe wartości k wystąpiły w kamieniołomach w Granicznej, Strzegomiu, Rogoźnicy i Goczałkowie (0,5-1,5 m/d), a najwyższe w rejonie Kostrzy i Zimnika (1,5-6 m/d).
Wartości współczynnika porowatości dla pokryw gliniastych mieszczą się w granicach od 0,17 do 0,35 (średnio 0,28).Wartości współczynnika porowatości dla zwietrzelin ziarnistych są znacznie wyższe. W górnej części profilu wynosząod 0,3 do 0,45 (średnio 0,38), a w dolnej wahają się od 0,38 do 0,46 (średnio 0,43).
Wartości współczynnika filtracji k od 0,7 do 71,5 m/d (średnio 13,02 m/d), określonego w warunkach laboratoryjnych dla gliniastych pokryw zwietrzelinowych, nie różnią się znacznie od wartości uzyskanych dla gliniastych pokryw stokowych granitu karkonoskiego.
Odsączalność grawitacyjna została wyznaczona jedynie dla zwietrzeliny ziarnistej. Wynosi ona od 0,17 do 0,24 (średnio 0,22). Najniższymi wartościami cechują się zwietrzeliny w rejonie Strzegomia i Kostrzy, a naj­wyższymi w rejonie Granicznej i Borowa.
Zwietrzeliny ziarniste stanowią strefę tranzytu wód infiltracyjnych do strefy saturacji. Przepływ odbywa się tu w nienasyconym ośrodku skalnym, wskutek czego powstaje nieciągła powierzchnia piezometryczna. Pokrywy zwietrzelin gliniastych mogą tworzyć warunki naporowe dla pierwszego od powierzchni terenu poziomu wód porowo-szczelinowych, które występują w strefie spękanego granitu i w zwietrzelinach ziarnistych. Mogą one stanowić także barierę ochronną przeciw zanieczyszczeniom z terenu.
Wartości parametrów hydrogeologicznych zwietrzelin granitów strzegomskich sąpodobne do wartości zmie­rzonych na obszarze granitu karkonoskiego. Można więc przypuszczać, że prędkość migracji zanieczyszczeń będzie podobna (około 2 m/rok).
Na podstawie średnich wartości miąższości i odsączalności zwietrzelin gliniastych i ziarnistych, oceniono pojemność wodną zwietrzelin na około 110 mm.

Streszczenie
Praca dotyczy możliwości wykorzystania olejów z pirolizy węgla brunatnego i zastosowania ich w sposób opisanyponiżej. Po pierwsze, próbki węglabrunatnego zostały pobrane z największego Regionu (Ceskoslovenska Armada Mine) i Regionu Sokolov (MineJiri) i odpowiednio przygotowane w celu uzyskania wymaganej wielkości ziarna. Próbki węgla były poddane pirolizie w zamkniętym reaktorze rurowym w temperaturze 900°C (5°C/min, przez okres 30 minut), a uzyskanym produktem była ciecz. Skład tych olejów pirolitycznych (alifatyczne i aro­matyczne węglowodory, alkohole i grupy funkcyjne) jest analogiczny jak w przypadku odczynników konwen­cjonalnych do flotacji węgla (w tym przypadku Montanol 800). Oleje użyto w procesie flotacji szlamów węgla kamiennego z Regionu Karwiny (z kopalni Lazy i osadnika z kopalni Darkov). Oleje pirolityczne stosowano w mieszaninie z Montanolem 800 w dawce 500 g/Mg i proporcje poszczególnych odczynników różniły od 1:4 do 5:0 (pirolityczny olej: Montanol 800). Ostateczne wartości, czyli uzysk koncentratu i zawartość popiołu, zostały porównane z wartościami uzyskanymi przy zastosowaniu czystego Montanolu 800. Zawartość popiołu w kon­centracie flotacyjnym została ustalona na poziomie 10%. Węgiel zawiera siarkę, której związki sąprzeniesione do płynnych produktów podczas pirolizy. Niektóre próbki węgla brunatnego poddano bakteryjnemu odsiarczaniu węgla stosując czyste kultury bakterii Ferrooxidans Acidithiobacillus w celu ustalenia, czy zawartość siarki ma wpływ na wyniki flotacji. Wyniki potwierdziły, że oleje pirolityczne mogą być stosowane do flotacji szlamów węgla, a otrzymane koncentraty będą zawierać poniżej 10% popiołu. Jednak może to być osiągnięte jedynie poprzez zmieszanie olejów z Montanolem 800; stosowanie samego oleju pirolitycznego nie dało zadowalających wyników. Pośrednim wynikiem eksperymentu było określenie ciepła spalania i wartości gazu pirolitycznego. Wyniki sugerują, że może on być stosowany jako paliwo alternatywne.

Chloroform extracts of the fruit shell, leaves, root bark, root wood, seeds, stem bark and stem wood of Derris indica Bennet. were tested against the brine shrimp, Artemia salina nauplii. All the test extracts of D. indica were found to be effective. The LC50 values of the extracts were 15312.37, 92.074 and 29.661 ppm for the fruit shell; 60922.83, 61.522 and 23.777 ppm for the leaf; 15312.37, 51.477 and 19.169 ppm for the root bark; 2598.584, 30.480 and 8.260 ppm for the root wood; 545.025,26.730 and 7.719 ppm for the seed; 60922.83, 114.549 and 29.572 ppm for the stem bark and 7734.618, 58.501 and 23.694 ppm for the stem wood at 30 minute, 24 hours and 48 hours post exposures respectively at doses 200, 100, 50, 25, 12.5, 6.25, 3.125 and 1.563 ppm against A. salina . The toxicity of the extracts could be arranged in the order: seed > root wood > root bark> stem wood > leaf > fruit shell > stem bark extract. However, the extracts did not significantly inhibit the germination of mustard oil seeds, and thus its application to crops or to the crop field may not cause any harm to crop plants.DOI: http://dx.doi.org/10.3329/ujzru.v31i0.15402Univ. j. zool.

Die fränkische Stadt Jaffa im Lichte jungster Ausgrabungen, von Martin Peilstöcker
Die in Jaffa durchgeführten Rettungsgrabungen ermöglichten es in den letzten Jahren, zahlreiche Reste der fränkischen Stadt zu Tage zu fördern, insbesondere Häuser, aber auch Elemente der Stadtmauern. Es war somit möglich, in bestimmten Zonen eine Chronologie der Befestigungen klarzumachen - insbesondere an der Seeseite, und nachzuweisen, dass die fränkische Stadt eine weitaus größere Ausdehnung besaß, als man bisher angenommen hat. Dieser Artikel bietet eine erste Synthese dieser bislang unpublizierten Ergebnisse an.
A Clinical, Laboratory and Microbiological Evaluation on Efficacy of Dental Air Force Home Dental Cleaning System on Type 2 Diabetic and Nondiabetic Adult Chronic Periodontitis Patients: A 6-Month Clinical Study
Authors: Mani Ameet Madan 
Published: June 2013

ABSTRACT

Aim
The study outlined to evaluate the clinical, laboratory and microbiological efficacy of Dental Air Force home dental cleaning system on type 2 diabetes and nondiabetic adult chronic periodontitis patients.

Materials and methods
A total of 100 adult chronic periodontitis subjects were recruited voluntary for this study. Clinical [plaque index (PI), gingival index (GI) and clinical attachment loss (CAL)], laboratory (C-reactive protein levels and glycated hemoglobin) and microbiological parameters were measured prior to phase 1 therapy; at 3rd and 6th month post phase 1 therapy. Comparative assessment was done among all the patients that were divided into four groups with Student paired t-test and analysis of variance (ANOVA).

Results
The results of this study showed that there was significant decrease in clinical, laboratory and microbiological parameters from baseline to 6 months in all the groups (i.e. p < 0.01). The subjects under groups using Dental Air Force home dental cleaning system showed highly significant reduction to all the parameters as compared to subjects under groups using toothbrush.

Conclusion
There was strong correlation between periodontal diseases and systemic parameters. Dental Air Force home dental cleaning system with the access to interdentally area helps in preventing the accumulation of dental plaque biofilm, thus able to maintain the clinical, laboratory and microbiological parameters at much lower levels as compared to traditional tooth brushing after phase I therapy.

Published: June 2013

ABSTRACT
The aim of the present article was to describe interdisciplinary orthodontic/prosthetic treatment performed in a patient with falciform anemia. The patient presented with the loss of several teeth and required prosthetic rehabilitation after tooth position correction with the use of an orthodontic appliance. After having orthodontic treatment performed with the application of forces as close as possible to the intensity of physiologic forces, rehabilitation was performed with removable partial dentures in the maxillary and mandibular arches. The results achieved were an improvement in tooth positioning, re-establishment of masticatory function and dental esthetics.
