Authors: Lee Eun-Ji , Kim Seong-Cheon
Published: June 2024

This study utilized the IPA technique to compare and analyze public and private distance education platforms, aiming to identify the requirements for public distance education platforms. The research involved surveying 314 teachers who had experience using both public and private distance education platforms, assessing their perceptions of importance and satisfaction regarding these platforms. IPA analysis was conducted based on average scores of importance and satisfaction, using Borich's Needs Assessment and the Locus for Focus model to prioritize requirements. The results are as follows:
Firstly, the top three prioritized factors in distance education platforms were identified as follows: 1) stable system operation, 2) data privacy protection features, and 3) real-time video lecture capabilities.
Secondly, the satisfaction level with public distance education platforms was generally lower than that with private platforms across most aspects. Particularly, various elements of learning experiences such as collaborative document editing, real-time video lectures, and learning data storage and analysis were found to be lacking in public platforms compared to private ones.
Thirdly, the priority requirements for public distance education platforms were identified as follows: real-time video lecture environment, collaborative document editing and learning together by multiple users, stable system operation, learning data storage and analysis, individual learner feedback, user opinion collection and incorporation, continuous feature updates, device compatibility, and individual assignment functions.

Published: June 2024

Permasalahan utama yang dialami oleh mitra kami yakni usaha ternak kambing milik Bapak Burhanuddin meliputi permasalahan di bidang produksi pakan fermentasi, manajemen usaha serta budidaya ternak.Â  Permasalahan bidang produksi pakan fermentasi basah meliputi jumlah atau kuantitas pakan fermentasi yang terbatas dan lamanya proses produksi pakan dikarenakan produksi pakan ternak dilakukan sendiri oleh mitra secara manual. Cara produksi pakan fermentasi yang dilakukan secara manual menyebabkan kuantitas pakan yang dihasilkan menjadi tidak maksimal, selain itu akan lebih banyak waktu yang tersita untuk menghancurkan bahan pakan berupa batang pisang karena ukuran batang pisang yang besarÂ  sedangkan alat yang digunakan masih sangat sederhana. Solusi yang ditawarkan adalah : 1. Alat dan mesin produksi pakan ternak agar dapat meningkatkan efektifitas dan efisiensi proses produksi pakan ternak; 2. Pelatihan cara beternak/budidaya (komposisi pakan berkualitas, pemberian vitamin dan vaksin, sanitasi kandang) agar proses penggemukan domba pedaging bisa lebih efektif dan efisien dikarenakan bila nutrisi dan kesehatan domba senantiasa terjaga maka capaian bobot domba standart dapat segera tercapai dalam kurun waktu pemeliharaan ternak yang lebih singkat (sesuai target); 3. Pelatihan manajemen usaha (analisa usaha) dan manajemen pemasaran (strategi pemasaran ternak domba) agar mitra dapat mengelola usaha ternaknya lebih baik, mitra juga dapat melakukan analisa kelayakan usaha ternaknya, dapat menghitung keuntungan bersih yang dapat diperoleh besar BEP (titik impas) serta dapat memperluas daerah pemasaran ternaknya bila kelak jumlah ternak kambing mitra semakin meningkat, 4. Perbaikan kendang. Adapun target luaran yang diharapkan akan dihasilkan oleh kegiatan PKM ini adalah: 1. alat dan mesin produksi pakan fermentasiÂ  berupa mesin pencacah batang/bonggol pisang, 2. komposisi pakan berkualitas, pemberian vitamin dan vaksin, sanitasi kandang; 3. manajemen usaha yang baik dan strategi pemasaran ternak domba dengan menggunakan media online.Â Â  Selanjutnya publikasi artikel dalam prosiding, publikasi media cetak dan video kegiatan PKM.

Kejadian kanker serviks masih tinggi, ironisnya kesadaran untuk melakukan deteksi dini masih rendah. Padahal, salah satu metode deteksi dini kanker serviks yaitu inspeksi visual melalui asam asetat (IVA) dapat dijangkau di layanan kesehatan dasar seperti puskesmas. Demi meningkatkan kesadaran deteksi dini, hadirlah SINARA sebagai instrumen untuk mendeteksi risiko kanker serviks yang dapat dilakukan sendiri oleh wanita usia subur. Kegiatan Pengabdian Kepada Masyarakat ini dilaksanakan di Desa Amahusu, Kecamatan Nusaniwe, Kota Ambon dengan sasaran mitra Pemerintah Desa Amahusu. Permasalahan yang dihadapi mitra Pemerintah Desa Amahusu, yaitu: 1) rendahnya pengetahuan kader kesehatan tentang program deteksi dini kanker serviks; 2) kurangnya keterlibatan kader kesehatan dalam program deteksi dini kanker serviks. Kegiatan yang dilakukan untuk mengatasi permasalahan mitra, yaitu: 1) penyuluhan tentang program deteksi dini kanker serviks; 2) pelatihan pengisian instrumen SINARA kepada kader. Penyuluhan dan pelatihan telah dilakukan kepada mitra. Penyuluhan dilakukan oleh narasumber yang mumpuni di bidangnya, juga merupakan tim, untuk meningkatkan pemahaman tentang deteksi dini kanker serviks. Pelatihan dilakukan oleh tim untuk pengenalan dan keterampilan penggunaan instrumen. Sebelum dan sesudah proses penyuluhan dan pelatihan, dilakukan tes untuk mengukur pemahaman kader selama kegiatan.

SEMINAR TENTANG METODE RESPONSI FISIK TOTAL (RFT) / TOTAL PHYSICAL RESPONSE (TPR) DALAM PEMBELAJARAN & PENGAJARAN BHS INGGRIS DI SMP NEGRI 19 AMBON
Authors: Harsono Debora
Published: June 2024

Fakta menunjukkan, bahwa permasalahan pembelajaran dan pengajaran Bahasa Inggris sangatlah kompleks. Pertama, Materi Pelajaran Bahasa Inggris cukup sulit untuk sebagian siswa. Seperti kita ketahui, Bahasa Inggris bukanlah bahasa yang kita ucapkan sejak balita. Secara pribadi, kita belajar Bahasa Inggris sebagai bahasa ketiga dalam kehidupan ini. Ketika batita kita memperoleh bahasa pertama dari ibu, kemudian kita mempelajari Bahasa Indonesia secara formal di bangku TK. Selanjutnya, kita mulai belajar bahasa Inggris di bangku SD atau SMP. Kedua, pengajaran Bahasa Inggris sangatlah membosankan bagi para siswa. Artinya meliputi pengajaran tata bahasa yang sangat rumit, hal ini diperburuk oleh guru Bahasa Inggris yang mengajar para siswa dengan menerapkan metode mengajar yang lama. Mengajar Tata Bahasa dengan banyak mengerjakan latihan tanpa penjelasan materi yang ringkas dan jelas. Banyak guru Bahasa Inggris berpendapat bahwa murid dapat memahami tata bahasa dengan mengerjakan sebanyak mungkin latihan. Belajar dengan menganalisa kesalahan dalam pengerjaan latihan soal tata bahasa. Ketiga, pengejaan dan pengucapan bahasa Inggris sangatlah berbeda dengan kata kata yang tertulis. Karena Bahasa Inggris tidaklah diucapkan sesuai dengan huruf yang tertulis (seperti Bahasa Jerman). Tentunya, hal ini menimbulkan beberapa kesulitan dalam pengejaan dan pengucapan Bahasa Inggris bagi kebanyakan siswa. Tetapi kebanyakan guru TK dan SD di Ambon cenderung menerapkan metode yang lama daripada yang baru. Karena menerapkan metode yang terbaik, berarti kita harus meluangkan lebih banyak waktu, perhatian dan energi untuk mempersiapkan segala sesuatunya dengan baik. Berdasarkan hal itu, maka penulis menyampaikan Seminar tentang Metode RFT dlm Pembelajaran dan Pengajaran Bahasa Inggris untuk para guru tetap mata pelajaran yang mengajar Bahasa Inggris di SMP Negri l9 Ambon pada hari Sabtu tertanggal 5 November 2022. Akhirnya, penulis menyimpulkan bahwa penerapan Metode Responsi Fisik Total (RFT) bagi Pembelajaran dan Pengajaran Bahasa Inggris bukanlah suatu hal yang mudah karena membutuhkan lebih banyak keseriusan, kesungguhan dan pengobanan waktu di dalam mempersiapkan semua materi pengajaran sekaligus menerapkannya dalam proses Pembelajaran dan Pengajaran Bahasa Inggris bagi anak didik kita

Published: June 2024

The appropriate U-turn area management is one of the methods of leveling safe roads. The objective of this research is to study and assess the consistency of physical characteristics of the U-turns with the current traffic flow. The research team has studied 14 U-turn points in Nakhon Ratchasima Province from the survey of physical characteristics, traffic volume, and traffic flow speed. When assessing the effectiveness of U-turns compared to the standard of the length of the awaiting section, in terms of the speed, traffic volume of the conflicting point of the traffic flow, and the standard width of the road medians, it was found that the U-turn point with the length of the awaiting section is sufficient for the current traffic volume, accounting for 35.71%. The road median width is wide enough to allow cars to safely make a U-turn in the innermost lane accounting for 28.57%. Thus, the current data of this study potentially reflect the suitability of U-turns and reality, such as the traffic lane length to reduce speed, areas for waiting queues, U-turn types, etc., by designing a prototype for managing a safe U-turn to propose as a guideline for further development to reduce future accidents all over the place of that U-turn.
Interculturalidade nas escolas indígenas do Brasil: as pedagogias ancestrais e a utilização das línguas maternas nas práticas educacionais no ano de 2022
Authors: Wenczenovicz Thaís Janaina , Monteiro Jade de Oliveira
Published: June 2024

A educação escolar indígena intercultural e bilíngue é um direito social fundamental reconhecido aos Povos Indígenas pela Constituição Federal do Brasil em 1988. As escolas indígenas foram criadas em 1999 para atender essa demanda constitucional, contudo, ainda existem defasagens no respeito aos processos próprios de aprendizagem e na utilização das línguas maternas. Essas dificuldades na implementação de práticas interculturais podem ser observadas por meio da análise de dados provenientes do Censo Escolar coletados pelo INEP/MEC no ano de 2022. A partir das informações apresentadas, é possível identificar alguns poucos avanços e as muitas contradições presentes nas escolas indígenas brasileiras. No entanto, florescem iniciativas dedicadas em contribuir com a superação deste cenário, voltadas para a formação intercultural de docentes indígenas e na construção de novas perspectivas epistêmicas. Utiliza-se do procedimento metodológico bibliográfico-investigativo.

Unveiling the Prospects of General Teacher While Teaching Students with Visual Impairment
Authors: Baraily Khagendra
Published: June 2024

It is a common practice around the world to teach disabled students in regular classes using transformative pedagogy. One of Nepal's inclusive education strategies for implementing the Basic and Primary Education Master Plan (1997) is to teach visually impaired students in regular courses using an integrated approach. Students with a range of needs, interests, and learning capacities make up the general class. Students with different needs attain learning at different rates. The teachers in integrated school use traditional methods to teach, which results in low achievement among the visually impaired children. This study aimed to explore the lived experience of a general teacher while teaching in an integrated classroom and the challenges faced by teacher in serving students with visual impairment in the mainstream classroom. The research design employed for this study is qualitative with interpretative phenomenology which depicts the perception and challenges experienced by teachers while teaching in the general classroom. Four general teachers who teach Nepali and mathematics were purposively selected from the integrated school located in the Bhaktapur district with voluntary participation. The participants were interviewed to share experiences via semi-structured guidelines. The interviews were transcribed verbatim and analyzed by the thematic process. The transcription was read and reread more times and categorized to generate a basic theme. The themes are further reorganized by searching commonalities to extract a global theme which was described by linking with theoretical insight. The challenges explored from the perception were problems of class control, content modification, excessive workload, inclusion problems, problems of classroom discourse, assignment and assessment, lack of professional development opportunities, difficulty to engage learners, inflexibility in time and resource lack of knowledge for instructional planning. The finding contributes to adopting instructional strategies and creating an inclusive environment in classroom instruction. This also becomes a milestone for implementing diversity management for addressing the diverse needs of learners.

Active components in medicinal plants possess therapeutic indications in disease states.
Aim: The present investigation evaluated the activity of fraction from Dryopteris dilatata leaves modulating diabetogenic and oxidative stress activity in alloxan-induced diabetic Rats.
Methods: Seventy-two male (135-140)g wistar rats divided into two groups of thirty-six rats each for oral glucose tolerance test and diabetic study. Diabetic induction and oral glucose test (OGTT) was done using standard methods. Each group was divided into six sub-groups (n-6). Group A was normal control, group B diabetic control, group C received metformin 50 mg/kg, group D reducing sugar fraction 800 mg/kg, group E alkaloid fraction 800 mg/kg and group F tannin fraction 800 mg/kg once for OGTT and daily throughout the treatment period (15 days) for diabetic study. Their glucose level was taken at interval of hours for OGTT and five days interval for diabetic group. We assessed the levels of lipid profile (TC, TG, LDL and HDL), lipid peroxidation, endogenous antioxidants in the brain and testis.
Results: Fractions of Dryopteris dilatata caused significant reduction in body weight and blood glucose levels in experimental rats, decreased the levels of TC, TG, LDL, increased HDL, reduced  levels of MDA, elevated CAT, GSH and SOD in the brain and testis.
Conclusion: The observed results in this study connotes that fractions of Dd could be used in amelioration of diabetes and its associated complications by reducing bad cholesterol (TC, TG and LDL), increasing good cholesterol (HDL), attenuating the activity of antioxidants in diabetic condition.
Correlates of Ghanaian Teachers' Understanding of Mathematics Strands and Cognitive Domains in Basic Education Certificate Examination
Authors: Eunice Osei-Asibey
Published: June 2024

In the field of mathematics education, it is essential to grasp teachers' competence in recognizing cognitive domains, as it plays a pivotal role in elevating teaching methods, evaluation techniques, and ultimately enhancing student academic achievements. This study examines the proficiency of basic school teachers in Ghana in identifying the cognitive domains of mathematics questions using Bloom's Taxonomy. A sample of 338 teachers from across the regions of Ghana participated, selected through random sampling. Teachers were assessed using a set of 50 Basic Education Certificate Examination (BECE) past questions spanning a decade (2010-2022), covering Algebra, Geometry and Measurement, Data, and Number strands. Participants categorized each question according to Bloom's Taxonomy. Poisson regression analysis and Confirmatory Factor Analysis were employed to evaluate teachers' proficiency. Results indicated a statistically significant intercept term, suggesting a baseline performance level among teachers. Significant interaction effects between demographic and professional characteristics (Class:category, Class:SchTyp, TeachEx:SchTyp, TeachEx:Domain, and the main effect of Domain) influenced teachers' ability to identify mathematics domains. Teaching experience positively influenced scores, while school type had a negative impact. The model demonstrated high discriminatory power and strong predictive performance with an AUC of 0.996. Dependency analysis revealed that understanding Bloom's taxonomy domains influenced the identification of mathematics strands. Primary level teachers’ consistently demonstrated higher proficiency compared to Junior High School (JHS) level teachers. Additionally, experienced and qualified professionals performed better than pupil teachers. These findings highlight the importance of targeted interventions and professional development programs to enhance teachers' competency in identifying mathematics domains, thus improving mathematics education in Ghana.

Published: June 2024

The present investigation was carried out with forty Niger genotypes at multi-environments for assessment of genotype x environment interaction and identification of high yielding and stable genotypes of Niger crop. Forty Niger genotypes were tested across five multi-environments in a randomized block design with replication thrice during Kharif, 2018 and Kharif, 2019. Combined analysis of variance and AMMI analysis of pooled data showed that genotype, environment and GEI effect were highly significant (p < 0.01) for seed yield. As per AMMI GGE biplots, two different mega-environments (METs) were identified, the first MET consists E1, E3 and E4 which are potential and excellent sites for discrimination of superior genotypes and second MET includes E2 and E5 were stable places. The genotypes, G28, G33, G8, G17, and G3 (seed yield plant-1), and G6, G33, G8, G17 and G3 (seed yield plot-1) were suitable for favorable environments while G4 and G7 (seed yield plant-1), and G27, G20, G1, G37 and G25 (seed yield plot-1) were suitable for unfavorable environments. Considering all the stability parameters and AMMI GGE biplots, genotypes, G36, G32, G24 and G10 had high mean seed yield and stable across the environments. These superior genotypes about grain yield and GEI impact, and can be recommended for future investigations.
An Evaluation of Environmental Contamination on Public Health: A Review of Air Pollution in Nigeria
Authors: Ucheje Okoroafor, Okechukwu , Ikebude Chiedozie, Francis
Published: June 2024

Numerous researchers have recognized environmental contamination as a potential danger to both the ecosystem and the general population's health. However, studies have shown that air pollution is a substantial contributor to a variety of respiratory conditions, including chronic obstructive pulmonary disease (COPD), shortness of breath, respiratory infections, and other similar conditions. To counteract this, however, the formulation and execution of public health policies might be of assistance in the fight against environmental pollution. In this study, the researchers investigated the ways in which air pollution, being a kind of environmental contamination, leads to problems in public health. In light of this, we reviewed the assessment of surveillance and monitoring, the consequences of human exposure to air pollution on public health, the influence of environmental pollution on social behaviors, as well as the ethical and legal implications of environmental contaminations. The study came to the conclusion that it is imperative to initiate possible action, since reducing the amount of air pollutants and chemicals in the environment may assist in avoiding further consequences of environmental degradation as well as limit the amount of harm done to human health. As a result, it is necessary to include monitoring of ambient PM2.5 and other air pollutants over a long length of time at a number of places that are typical of important metropolitan activities. These areas include trash dumps, transportation, and manufacturing facilities.
Interventional approaches to deep vein thrombosis
Authors: Vedantham Suresh
Published: February 2012

The last decade has seen increased use of aggressive, catheter‐based methods of treating deep vein thrombosis (DVT). In this article, we outline the risks, benefits, and uncertainties surrounding endovascular DVT therapies, describe clinical situations in which endovascular treatment options should reasonably be considered, and update the reader on new outcome data that pertains to catheter‐based DVT interventions. Endovascular thrombolytic therapy is reasonable to perform for selected patients with DVT causing acute limb‐threatening circulatory compromise, acute inferior vena cava occlusion, or acute iliofemoral DVT for the purposes of limb salvage and relief of presenting DVT symptoms, and appears likely to prevent post‐thrombotic syndrome (PTS) in patients with proximal DVT. A multicenter randomized trial, the ATTRACT Study, is currently underway in the United States to determine whether pharmacomechanical catheter‐directed thrombolysis (PCDT) is sufficiently safe and effective to be recommended for routine use in proximal DVT patients. Selected patients with established moderate‐to‐severe PTS in association with an occluded iliac vein or a refluxing saphenous vein may also be amenable to endovascular intervention to reduce venous hypertension, alleviate symptoms, and improve limb function and quality of life. Pending the results of further studies, an individualized approach to patient selection for interventional DVT therapies is recommended. Am. J. Hematol. 2012. © 2012 Wiley Periodicals, Inc.

After maternal exposure to mycophenolate in pregnancy a high number of fetal losses and a specific pattern of birth defects consisting of microtia, cleft lip, and other anomalies have been reported. However, so far, prospective data on pregnancy outcome allowing quantitative risk assessment are missing. We report on 57 prospectively ascertained pregnancies after maternal therapy with mycophenolate (mycophenolate mofetil or mycophenolate sodium) identified by European Teratology Information Services (ETIS) through their risk consultation process. The outcome of these prospective pregnancies was as follows: 16 spontaneous abortions, 12 elective terminations of pregnancy (ETOP) (including two late terminations for multiple malformations consistent with mycophenolate embryopathy), and 29 liveborn infants. The probability of spontaneous abortion was about 45% (95% CI 29 to 66%) estimated using survival analysis technique. Six out of 29 live born infants had major congenital defects: Two with external auditory canal atresia (EACA) (with and without microtia), one with tracheo‐esophageal atresia, one with severe hydronephrosis, one with an atrial septal defect (ASD) and one with a myelomeningocele. Thus, at least four fetuses/infants of our prospective case series had a clinical phenotype consistent with mycophenolate embryopathy. Our results confirm a high incidence of major malformations (26%) after first trimester exposure to mycophenolate. Apart from exposure to mycophenololate, the underlying maternal disease and concomitant medication may also have contributed to the other poor pregnancy outcomes such as a high rate of spontaneous abortions, prematurity (62%), and low birth weight (31%). © 2012 Wiley Periodicals, Inc.
Hormonal and Experiential Predictors of Infant Survivorship and Maternal Behavior in a Monogamous Primate (Callicebus cupreus)
Authors: JARCHO MICHAEL R. , MENDOZA SALLY P. , BALES KAREN L.
Published: February 2012

To better understand the roles that hormones and experience play in infant survival and maternal behavior in a biparental primate species, we analyzed urinary estrone (E1C) and pregnanediol glucuronide (PdG) from 24 socially housed titi monkey (Callicebus cupreus)females over 54 pregnancies (N = 1,430 samples). Pregnancies were categorized according to whether the infant survived (N = 35) or not (N = 19), and by maternal parity (primiparous:N = 9; multiparous:N = 45). Mothers of infants that survived had a significantly greater drop inPdGfrom the third trimester to the first week postpartum than mothers of infants that did not survive. Multiparous mothers had a greater increase inPdGfrom the first to the third trimester as well as greater increases in theE1C:PdGratio from the first to the third trimester and from the third trimester to the first week postpartum. There were positive relationships between third trimesterPdGand maternal carrying and nursing during the first week postpartum, and between maternal age and carrying during the infant's first month of life. There was a negative correlation between maternal age andPdGduring the third trimester. These results suggest that elevated progesterone during late pregnancy followed by progesterone withdrawal immediately following parturition is associated with greater probability of infant survivorship and maternal behavior in this species, and that older females engage in more postpartum maternal care.

Juggling Priorities: Female Mating Tactics in Phayre's Leaf Monkeys
Authors: LU AMY , BEEHNER JACINTA C. , CZEKALA NANCY M. , BORRIES CAROLA
Published: February 2012

Extended sexual receptivity in primates is thought to facilitate paternity confusion, thus decreasing the risk of infanticide. However, females might also provide some indication of ovulation to attract preferred males during fertile periods. We examined female mate preferences across defined receptive periods (N = 59) in a group of wild Phayre's leaf monkeys (Trachypithecus phayrei crepusculus) at Phu Khieo Wildlife Sanctuary (February–September 2006; 2,603 contact hours). The group contained seven cycling adult females and three reproductively active males (one adult and two adolescents). We predicted that females would prefer the adult male during periovulatory (POP) receptive periods, but the adolescent males during nonperiovulatory (NPOP) and postconceptive (PC) periods. We collected focal and ad libitum data on sexual and agonistic behaviors to determine female preferences and male awareness of female fertility. We also determined the degree of mating overlap to assess if males were capable of monopolizing females. Our results indicate that females were more frequently proceptive and receptive toward the adult male during POP. By contrast, females were more proceptive and receptive toward one of the adolescent males during PC periods, but rarely interacted with the other adolescent. Patterns of attractivity and agonism across receptive periods suggested that the adult male could detect fertility, while the preferred adolescent could not. Finally, we found a high degree of overlap in total receptive period days, but a low degree of overlap in POP receptive days, suggesting that the adult male might have monopolized females, especially since he seemed to be aware of female fertility. Although these results suggest that females provide some information on ovulation, they also suggest that females attempt to confuse paternity, perhaps capitalizing on male differences in the ability to detect fertility.

Hybrid compounds of molybdovanadophoric heteropolyacids and a Schiff base transition metal complex, M‐saldmp or M‐fpdmp (M = Fe(II), Co(II), Cu(II)), were successfully prepared and found to be effective catalysts for direct hydroxylation of benzene with H2O2. The synergistic effect between Schiff base metal complex and heteropolyacid plays an important role in the promotion of catalytic activity. Copyright © 2012 John Wiley & Sons, Ltd.

Technical possibilities for load tests of concrete and masonry bridges.

The experimental safety evaluation of existing concrete and masonry bridges is discussed. There are different technical methods for generating test loads in situ: the utilization of hydraulic actuators and reaction frames, the application of the loading vehicle BELFA, and the measurement of the structural response during vehicle crossing. For each of the three methods, an application example is presented. The technical characteristics and the limitations of the methods are compared.
Aktive Schwingungskontrolle einer Spannbandbrücke mit pneumatischen Aktuatoren
Authors: Bleicher Achim
Published: February 2012

Neue Materialien und Technologien erlauben nicht nur Entwurf und Konstruktion ultraleichter und schlanker, sondern auch nachhaltiger Brücken. Mit dem höchstfesten Material kohlenstofffaserverstärkter Kunststoff wurde eine Spannbandbrücke entworfen und gebaut, die mit nur 1 mm Konstruktionshöhe 13 m weit spannt. Um ihre außergewöhnlich hohe Schwingungs anfälligkeit unter Fußgängerverkehr zu reduzieren, wurde eine aktive Schwingungskontrolle entwickelt und an einem Prototypen getestet. Das Konzept zur aktiven Schwingungskontrolle basiert auf dem geregelten Eintrag von Kräften in die Geländerkonstruktion. Zum Einsatz kommen Sensoren, Regelungskonzepte und biologisch inspirierte Aktuatoren, die als aktives System die ersten drei vertikalen Eigenschwingungen der Brücke kontrollieren. Ein wesentliches Element im Entwicklungsprozess des aktiven Systems ist die analytische Modellbildung der Spannbandbrücke, welche dem Entwurf modellbasierter Regelungen zur Kontrolle der Brückenschwingungen dient. Die Effektivität der aktiven Schwingungskontrolle zeigt sich dann durch eine deutliche Reduktion fußgängerinduzierter Beschleunigungen um bis zu 90 % und bestätigt damit auch das Potenzial aktiver Systeme.

Multimodal active vibration control of a stress ribbon bridge using pneumatic muscle actuators.

New materials and technologies not only allow building ultralight and slender bridges, they also enable the construction of sustainable bridges. By using high‐strength carbon fibre reinforced plastic, a very light and flexible stress ribbon footbridge with a span of 13 m and a structural height of only 1 mm was designed and built in the lab of the Chair of Conceptual and Structural Design at TU Berlin. In order to counteract the high level of pedestrian‐induced vibrations, an active vibration control concept was developed and applied to the prototype. This concept consists of sensors, closed loop controls and biologically inspired actuators. The actuators are embedded into the handrail to control the first three vertical modes of the bridge. One basic element for the development of the active system is the modelling of the bridge to design model‐based controller. The efficiency of the multimodal active vibration control and the potential of active systems are shown by an enormous reduction of pedestrian‐induced accelerations up to 90 %.

Published: February 2012

A new magnetic resonance imaging (MRI) contrast bearing RGD peptide is reported. In this study, ultrasmall superparamagnetic iron oxide (USPIO) nanoparticles with various sizes were prepared. Particles sizes between 6 and 13 nm were tuned by varying the stirring rate. Remarkable negative contrast was observed because USPIO nanoparticles (13.1 ± 2.1 nm) generated high transversal relaxivity r2 (188 ± 3 m m−1 s−1) and saturation magnetization (94 emu g−1 Fe). The USPIO nanoparticles were coated with PDA [2‐(pyridyldithio)‐ethylamine; PDA nanoparticles] containing functional polymer, which can be readily synthesized by Michael addition. The PDA nanoparticles were conjugated with RGD peptide (RGD nanoparticles) for targeting the specific site. The target specificity and high relaxivity allowed RGD nanoparticles to differentiate the expression level of integrin receptor on several cell lines and tumors (MCF‐7, A‐549, HT‐29 and HT‐1080) by in vitro and in vivo MR imaging. Importantly, a remarkable negative contrast (−51.3 ± 6.7%) was observed for in vivo MR imaging of MCF‐7 tumor. This result implies that the RGD nanoparticles that greatly enhance the MR imaging are highly sensitive for early stage tumor detection. Copyright © 2012 John Wiley & Sons, Ltd.
Molecular imaging: challenges of bringing imaging of intracellular targets into common clinical use
Authors: Skotland Tore
Published: February 2012

Molecular imaging (MI) takes advantage of several new techniques to detect biomarkers or biochemical and cellular processes, with the goal of obtaining high sensitivity, specificity and signal‐to‐noise ratio imaging of disease. The imaging modalities bearing the most promise for MI are positron emission tomography (PET), single photon emission computer tomography (SPECT) and different optical imaging techniques with high sensitivity. Also magnetic resonance imaging (MRI) with contrast agents like ultra‐small superparamagnetic iron oxide particles (USPIO), magnetic resonance spectroscopy and ultrasound imaging with contrast agents may be useful approaches. MI techniques have been used in the clinic for many years, i.e. PET imaging using 18 F‐labeled fluorodeoxyglucose. Animal studies have during the last years revealed great potential for MI also with several other agents. The focus of the present article is the challenges of clinical imaging of intracellular targets following intravenous injection of the agents. Thus, the great challenge of getting enough contrast agent into the cytosol and at the same time obtaining a low signal from tissue just outside the diseased area is discussed.

Nanoparticle‐based PARACEST agents: the quenching effect of silica nanoparticles on the CEST signal from surface‐conjugated chelates
Authors: Evbuomwan Osasere M. , Merritt Matthew E. , Kiefer Garry E. , Dean Sherry A.
Published: February 2012

Silica nanoparticles of average diameter 53 ± 3 nm were prepared using standard water‐in‐oil microemulsion methods. After conversion of the surface Si–OH groups to amino groups for further conjugation, the PARACEST agent, EuDOTA–(gly)4− was coupled to the amines via one or more side‐chain carboxyl groups in an attempt to trap water molecules in the inner‐sphere of the complex. Fluorescence and ICP analyses showed that ~1200 Eu3+ complexes were attached to each silica nanoparticle, leaving behind excess protonated amino groups. CEST spectra of the modified silica nanoparticles showed that attachment of the EuDOTA–(gly)4− to the surface of the nanoparticles did not result in a decrease in water exchange kinetics as anticipated, but rather resulted in a complete elimination of the normal Eu3+‐bound water exchange peak and broadening of the bulk water signal. This observation was traced to catalysis of proton exchange from the Eu3+‐bound water molecule by excess positively charged amino groups on the surface of the nanoparticles.
