Mechanical Properties of Polypropylene: Additive Manufacturing by Multi Jet Fusion Technology

Multi jet fusion (MJF) technology has proven its significance in recent years as this technology has continually increased its market share. Recently, polypropylene (PP) was introduced by Hewlett-Packard for the given technology. To our knowledge, little is known about the mechanical properties of polypropylene processed by MJF technology. During this study, standardised specimens were printed under all of the major orientations of the machine’s build space. Each of these orientations were represented by five samples. The specimens then underwent tensile, bending and Charpy impact tests to analyse their mechanical properties. The structural analysis was conducted to determine whether PP powder may be reused within the MJF process. The mechanical tests showed that the orientation of the samples significantly influences their mechanical response and must be carefully chosen to obtain the optimal mechanical properties of PP samples. We further showed that PP powder may be reused as the MJF process does not significantly alter its thermal and structural properties.

Мета дослідження – можливості профілактики ускладнень гестаційного процесу. Матеріали і методи. Першу групу спостереження склали 25 жінок, у яких при 28–30-тижневому терміні вагітності виникли початкові ознаки порушення життєдіяльності плода. Другу групу склали 25 жінок, яким з метою профілактики передчасних пологів із 22–24-тижневого терміну вагітності призначали вагінально мікронізований прогестерон прогінорм геста 200 мг на добу. Третю групу склали 25 вагітних групи ризику функціонального диференціювання плаценти, які з 22 тижня вагітності приймали прогестерон 200 мг на добу вагінально. Оцінку розвитку плода проводили за допомогою ультразвукової системи SA-8000 EX. Мінімальний об’єм фетометрії включав визначення біпарієтального розміру головки (БПР), довжини стегнової кістки (ДС) і середнього діаметра живота (ДЖ), визначали також кількість генералізованих (ГР) і тривалість епізодів постійних дихальних (ДР) рухів плода, використовували індекс ГР та індекс ДР. Реєстрацію кардіотахограми проводили монітором типу 8030 А фірми «Hewlett-Packard». Результати дослідження та їх обговорення. Проведені дослідження показали, що середній показник біофізичного профілю плода (БПП) у вагітних першої групи дорівнював (5,6±0,3) бала. При цьому базальна частота серцевих скорочень (БЧСС) у плода складала (171,3±4,3) уд./хв, спостерігався ундулюючий тип варіабельності. Амплітуда миттєвих осциляцій – (3,4±0,5) уд./хв, частота – (3,0±0,4) уд./хв, реєструвалися поодинокі (2,2±0,3) акцелерації помірної амплітуди ((16,5±0,8) уд./хв) і тривалості ((17,8±1,6) с). У 24 % випадків відмічені окремі (1,5±0,4) децелерації. Амплітуда останніх складала (18,5±1,7) уд./хв, тривалість (20,4±1,9) с. Було виявлено лише (2,3±0,5) ГР, поодиноких короткочасних ((25,5±3,4) с) епізодів постійних ДР. Індекс ГР складав (2,3±0,4) %, індекс ДР – (2,6±0,4) % (р˂0,05). У першій групі при наявності у 48 % випадків плацента відрізнялась високою ехогенністю. У вагітних другої групи виявили фетальний дистрес у 12 % випадків.

SPICE Behaviors of Double Memristor Circuits Using Cosine Window Function

In this paper, a Hewlett-Packard (HP) memristor model with a new window function and its versatile characteristics are presented. SPICE behaviors of the linear and nonlinear memristor model are studied through PSpice simulation. High flexibility is demonstrated for emulating the behaviors of the practical HP memristors. Furthermore, the characteristics of the composite SPICE behaviors are both investigated when two memristors are connected in series and in parallel. The polarity of each memristor is also taken into consideration. The relationships among flux, charge, voltage, current, and memristance of the double memristor circuits are simulated and analyzed.

History Erase Effect of Real Memristors

Different from the static (power-off) nonvolatile property of a memristor, the history erase effect of a memristor is a dynamic characteristic, which means that under the excitation of switching or different signals, the memristor can forget its initial value and reach a unique stable state. The stable state is determined only by the excitation signal and has nothing to do with its initial state. The history erase effect is a desired effect in memristor applications such as memory. It can simplify the complexity of the writing circuit and improve the storage speed. If the memristor’s response depends on the initial state, a state reset operation is required before each writing operation. Therefore, it is of great theoretical and practical significance to judge whether the memristor has a history erase effect. Based on the study of the history erase effect of real memristors, this paper focuses on the history erase effect of a Hewlett-Packard (HP) TiO2 memristor and the Self-Directed Channel (SDC) memristor of Knowm Company. The DC and AC responses of the HP TiO2 memristor are given, and it is pointed out that there is no AC history erase effect. However, considering the parasitic memcapacitance effect, it is found that it has the effect. Based on the theoretical model of the SDC memristor, its history erase properties with and without considering parasitic effects are studied. It should be noted that this study method can be useful for other materials such as Al2O3 and MoS2.

Assessing the in vitro impact of ceftazidime on aztreonam/avibactam susceptibility testing for highly resistant MBL-producing Enterobacterales

Background Aztreonam/avibactam is a combination agent that shows promise in treating infections caused by highly antibiotic-resistant MBL-producing Enterobacterales. This combination can be achieved by combining two FDA-approved drugs: ceftazidime/avibactam and aztreonam. It is unknown whether ceftazidime in the combination ceftazidime/aztreonam/avibactam has a synergistic or antagonistic effect on the in vitro activity of aztreonam/avibactam by significantly increasing or decreasing the MIC. Objectives To determine whether increasing ceftazidime concentrations affect the MICs of aztreonam/avibactam alone. Methods A custom 8 × 8 chequerboard broth microdilution (BMD) panel was made using a digital dispenser (Hewlett-Packard, Corvallis, OR, USA). The panel included orthogonal 2-fold dilution series of aztreonam and ceftazidime ranging from 0.5 to 64 mg/L. Avibactam concentration was kept constant at 4 mg/L throughout the chequerboard. Thirty-seven Enterobacterales isolates from the CDC & FDA Antibiotic Resistance Isolate Bank or CDC’s internal collection with intermediate or resistant interpretations to aztreonam and ceftazidime/avibactam were included for testing. All isolates harboured at least one of the following MBL genes: blaIMP, blaNDM or blaVIM. Results Regardless of the concentration of ceftazidime, aztreonam/avibactam with ceftazidime MICs for all 37 isolates were within one 2-fold doubling dilution of the aztreonam/avibactam MIC. Conclusions Ceftazidime, in the combination ceftazidime/avibactam/aztreonam, did not affect the in vitro activity of aztreonam/avibactam in this sample of isolates. These findings can help assure clinical and public health laboratories that testing of aztreonam/avibactam by BMD can act as a reliable surrogate test when the combination of ceftazidime/avibactam and aztreonam is being considered for treatment of highly antibiotic-resistant MBL-producing Enterobacterales.
