Published: September 2020

OBJECTIVEResidency work-hour restrictions necessitate efficient, reproducible training. Simulation training for spinal instrumentation placement shows significant benefit to learners’ subjective and objective proficiency. Cadaveric laboratories are most effective but have high cost and low availability. The authors’ goal was to create a low-cost, efficient, reproducible spinal instrumentation placement simulation curriculum for neurosurgery and orthopedic surgery residents using synthetic models and 3D computer-assisted navigation, assessing subjective and objective proficiency with placement of thoracolumbar pedicle screws.METHODSFifteen neurosurgery and orthopedic surgery residents participated in a standardized curriculum with lecture followed by two separate sessions of thoracolumbar pedicle screw placement in a synthetic spine model utilizing 3D computer-assisted navigation. Data were collected on premodule experience, time and accuracy of screw placement, and both subjective and objective ratings of proficiency.RESULTSFifteen of 15 residents demonstrated improvement in subjective (Physician Performance Diagnostic Inventory Scale [PPDIS]) and 14 in objective (Objective Structured Assessment of Technical Skills [OSATS]) measures of proficiency in navigated screw placement with utilization of this curriculum (p < 0.001 for both), regardless of the number of cases of previous experience using thoracolumbar spinal instrumentation. Fourteen of 15 residents demonstrated decreased time per screw placement from session 1 to session 2 (p = 0.006). There was no significant difference in pedicle screw accuracy between session 1 and session 2.CONCLUSIONSA standardized curriculum using synthetic simulation training for navigated thoracolumbar pedicle screw placement results in significantly improved resident subjective and objective proficiency. Development of a nationwide competency curriculum using simulation training for spinal instrumentation placement should be considered for safe, efficient resident training.

Früher Laubfall der Buche während der Sommertrockenheit 2018: Resistenz oder Schwächesymptom?
Die Sommertrockenheit 2018 führte in verschiedenen Regionen der Schweiz zum vorzeitigen Laubfall bei Bu-chen (Fagus sylvatica L.). Es stellte sich die Frage, ob dieser Laubfall als Resistenzreaktion aufgefasst werden soll, die den Buchen einen physiologischen Vorteil verschafft, oder als ausgeprägtes Schwächesymptom. Zur Beantwortung dieser Frage führten wir im Spätsommer 2018 Zustandserhebungen bei 781 ausgewachsenen Buchen mit frühem und 138 mit normalem Laubfall (insgesamt 919 Bäume) in den Regionen Aargau/Zürich (AG/ZH), Baselland (BL) und Schaffhausen (SH) durch. Erneute Begutachtungen und Probenahmen verschiedener Parameter im Frühling und Sommer 2019 zeigten, dass von den Buchen mit frühem Laubfall regional zwischen 1.4% und 4.7% abstarben. Die mittlere Kronenmortalität im Sommer 2019 betrug für Bäume mit frühem Laubfall in BL 35.6%, in SH 30.0% und in AG/ZH 17.4%. Bei Bäumen mit normalem Laubfall in der Nachbarschaft lagen die Werte nur bei 13.0% (BL) und 5.3% (AG/ZH). Die mittleren Mortalitätsraten stiegen 2019 vom Frühling bis zum Sommer an. Bäume mit frühem Laubfall trugen generell mehr Früchte (Mast-Effekt). In BL traten bei Bäumen mit frühem Laubfall signifikant mehr Rindenschäden und Nekrosen auf als bei Bäumen mit normalem Laub-fall. Bäume mit frühem Laubfall wurden dort häufiger von Buchenwollschildläusen befallen, und deren Blätter im Kronendach wurden stärker durch Insekten und Pilze beeinträchtigt. In AG/ZH wiesen die Bäume mit frühem Laubfall deutlich häufiger Schleimfluss auf, und sie standen öfter am Waldrand. Aufgrund unserer Resultate stellt der verfrühte Laubfall bei Buchen, wie er sich während der ausgeprägten Sommertrockenheit 2018 ereignete, ein Schwächesymptom dar, das durch die Beobachtung gestützt wird, dass viele Zweige und Äste im Jahr nach der Trockenheit nicht mehr ausgetrieben haben bzw. abstarben.

Published: September 2020

BACKGROUND: To ensure quality and stability, monitoring systems are recommended to analyze pharmaceutical manufacturing processes. OBJECTIVE: This study was performed to predict powder X-ray diffraction (PXRD) patterns of formulation powders through attenuated total reflectance (ATR)-infrared (IR) spectroscopy in a nondestructive manner along with chemometrics. RESULTS: Caffeine anhydrate, acetaminophen, and lactose monohydrate were grinded at six weight ratios. The six sample groups were evaluated using ATR-IR spectroscopy and PXRD analysis. Partial least squares models were constructed to predict the PXRD intensities of the samples from the ATR-IR spectra. The prediction accuracy on the prepared PLS regression models was as high as R2 = 0.993. CONCLUSIONS: Linear relationships were obtained between the prediction data set and reference PXRD intensity at each degree. 2D PLS regression coefficient analysis enabled the analysis of the correlation between PXRD patterns and IR spectra.
Investigation of a shape memory alloy releasable mechanism applied in space environment

Published: September 2020

Though the conventional pyrotechnic fastener mechanisms are widely used in spacecraft for their reliable releasable-fastening function, they still have several unavoidable problems: physical shock, high maintenance cost, to name a few. This paper introduces a new type of smart releasable mechanism based on a Shape Memory Alloy (SMA) spring and its corresponding heating apparatus. To obtain the high heating efficiency and increase the response speed, the SMA spring is transitionally fit with the heating apparatus shell instead of directly heating by electric current. As soon as the heating apparatus begins to work, the SMA spring will provide an un-locking force to release the fastening device within the standard time, which also realizes the similar releasable-fastening function comparing with the conventional pyrotechnic fastener mechanisms. In order to ensure the reliability of space products, the heating apparatus is composed of two identical ceramic heating elements which can be controlled independently or synchronously. Finally, the experimental results clearly show that, under the satellite power supply at the constant value of 28 V, the SMA spring can reach the desired 30 N unlocking force within 93 s and 51 s by single or dual heating elements, respectively. The maximal output force can even be increased as large as 40 N under the limited volume of the releasable mechanism.

Authors: Kurishima Yusuke , Hashimoto Hirokazu , Okuyama Takeshi , Tanaka Mami 
Published: September 2020

In this paper, a measurement system of swallowing motion is developed. A piezoelectric film is used as sensitive material of the sensor to measure the body surface deformation due to swallowing. We focused on laryngeal prominence and digastric muscle which are active during swallowing and developed sensors to attach to skin above laryngeal prominence and digastric muscle. As a result of experiments, it was confirmed that output fluctuation occurred at the swallowing. Next, by comparing the frequency spectral density distribution of sensor outputs during swallowing and resting, it was found that the output waveform during swallowing is mainly composed of larger frequency components below 20 [Hz] than that during resting. From the results, it was suggested that the developed measurement system is available to detect the swallowing from skin deformation without obstructing the motion.

Published: September 2020

In this paper, a kind of electromagnetic actuator is developed which can solve the problem of in time controlling inter-electrode gap in traditional EDM. An incoming current in the coil of an electromagnetic actuator generates Lorentz forces that cause the electrode to move axially. When the electromagnetic actuator is working, electrode is actuated positioned quickly, and electrode is produced a displacement of plus or minus 1 mm by control. The experiment shows that the response time of the electromagnetic actuator can meet the machining requirements. The discharge probability is increased and the machining efficiency is improved.
Analysis of nonlinear vibration energy harvesters using a complex dynamic frequency method
Authors: Wang Zhixia , Wang Wei , Zhang Qichang , Gu Fengshou , David Ball Andrew 
Published: September 2020

To understand the complicated dynamic behavior of a Nonlinear Piezoelectric Energy Harvester (NPEH), this paper develops an improved Complex Dynamic Frequency (CDF) method based on complex normal form. CDF introduces a dynamic frequency factor and establishes a set of algebraic equations in handling the effect of higher-order nonlinear terms in a wide frequency band to obtain periodic responses of NPEH. Numerical and experimental studies verify that the proposed CDF gives consistent and accurate predictions of the systems with both weak and strong nonlinearity. Furthermore, through an implicit relationship between magnet arrangement and output performance, one may effectively control the sweep frequency with softening and hardening characteristics. That is a major breakthrough toward the further nonlinear design for broad bandwidth harvesters. As the application, the experimental results reveal the high response profiles can be in a wide frequency range from 10.8 Hz to 24.5 Hz for the NPEH developed that allows an output power of 9 times higher than the conventional linear structure.

Authors: Aratani Shin’ichi , Egawa Hiroyuki , Ohmi Toshihito , Yokobori A. Toshimitsu 
Published: September 2020

Glass fracture and changes in bending load were investigated by the quasi-static loading method which is characterized by holding a fixed time at each displacement level and incrementally applying displacement. Holding time at each step was 60 s and the incremental displacement was 0.02 mm as the load condition. Ordinary soda-lime-silicate float glass of 50 × 10 × 4 mm was used as the specimen. The glass fracture occurred as the bending load decreased with time, which might be explained using the occurrence of time-dependent fracture and function as a viscoelastic property even at room temperature. Fracture properties of alumina ceramics have the possibility to be closer to float glass than silicon carbide which is called general ceramics.

Tuberkulosis (TB) paru sampai saat ini masih menjadi perhatian dunia dan menjadi salah satu indikator keberhasilan dalam Suistainable Development Goal (SDG’s). Laporan WHO menyatakan bahwa Indonesia termasuk 30 negara yang memiliki beban kasus TB yang besar. Di Indonesia, provinsi Jawa Tengah juga termasuk dalam provinsi yang memiliki beban kasus TB terbanyak. Penelitian ini bertujuan untuk mengetahui gambaran secara spasial hubungan kasus baru TB paru BTA (+ ) dengan kepadatan penduduk tahun 2016-2018. Populasi dalam penelitian ini yaitu penduduk Jawa Tengah di 29 kabupaten dan 6 kota yang tercatat di profil kesehatan Provinsi Jawa Tengah Tahun 2016-2018. Sampel adalah seluruh populasi. Variabel dalam penelitian ini yaitu kasus baru TB BTA (+) dan kepadatan penduduk yang tercatat di lampiran profil kesehatan Provinsi Jawa Tengah Tahun 2016-2018. Analisis data dilakukan dengan perangkat lunak Geoda. Hasil analisis spasial kasus baru TB BTA (+) dan kepadatan penduduk pada tahun 2016-2018 menunjukkan pola yang mengelompok namun setelah dilakukan uji signifikansi menunjukkan tidak adanya autokorelasi spasial. Hal ini menunjukkan bahwa kasus baru TB BTA (+) dengan kepadatan penduduk antar kabupaten/kota satu dengan yang lainnya tidak memiliki hubungan secara spasial, sehingga wilayah yang memiliki kasus baru TB BTA (+) dengan kepadatan penduduk tinggi tidak mempengaruhi wilayah lainnya menjadi tinggi pula.
Pengaruh Penyimpanan terhadap Kualitas Mikrobiologis Sambel Tumpang Pada Pedagang Nasi Pecel Tumpang
Authors: Pujianto Tutut , Budiman Frenky Arif 
Published: September 2020

Nasi pecel tumpang merupakan makanan asli Kediri yang tersebar merata di seluruh wilayah Kediri. Makanan tradisional ini selayaknya perlu mendapatkan perhatian bagi para penjual dan pembeli, terutama dari sisi kesehatan. Karena sambel tumpang tidak selalu habis disajikan dan harus dihangatkan berkali-kali. Keberadaan mikroorganisme dalam sambel tumpang bisa menjadi penyebab timbulnya keracunan makanan (food poisoning). Masuknya mikroba ke dalam makanan dapat terjadi pada tahap pemilihan bahan makanan, pengolahan dan penyajian makanan yang kurang tepat. Penelitian dilaksanakan di Kampung Inggris Pare, terhadap 15 penjual nasi pecel tumpang dengan desain crossectional. Tujuan penelitian adalah untuk menganalisis pengaruh penyimpanan terhadap kualitas mikrobiologis sambel tumpang, dengan empat parameter, yaitu APN Coiform, APM Eschericia coli, Salmonella sp., dan kapang. Pembuktian hypotesis dilakukan dengan menghubungkan skor inspeksi sanitasi dengan kualitas mikrobiologis sambel tumpang dengan menggunakan dengan uji coefisien contingensi (α:5%), menggunakan bantuan software statistik. Kesimpulan hasil penelitian adalah peralatan dan perlakuan penyimpanan tidak berpengaruh terhadap kualitas sambel tumpang, namun lingkungan penyimpanan berpengaruh secara nyata terhadap kualitas sambel tumpang (p value : 0,050). Dari empat parameter mikrobiologis, APM coliform adalah parameter yang dipengaruhi oleh lingkungan penyimpanan. Dari kesimpulan tersebut maka disarankan kepada pedagang untuk selalu membersihkan lingkunganya dari sampah dan menutup rapat wadah sambel tumpangnya.
