Pros And Cons

Abstract As part of my ongoing work with speakers that use uncommon technologies to project sound, this time I turned to the vibration speaker, a kind of transducer that, in order to radiate sound, coaxes a surface to vibrate by direct contact. Therefore, in this article, pros and cons of vibration speakers will be highlighted and, at the same time, I will proceed to illustrate a piano suite I assembled that uses an expressly built-for Android application as an interface between whatever sound is produced in, on or with the piano and the vibration speaker: the sound is captured by the microphone of the Android device, then it is processed by the application and eventually is sent via Bluetooth to the speaker sitting on the piano soundboard, through which it gets amplified. This relatively simple system allows for a large array of timbral possibilities and unconventional ways of playing the piano.

AbstractWe present a review of the field of formaldehyde (H2CO) 6cm masers in the Galaxy. Previous to our ongoing work, H2CO 6cm masers had been detected in the Galaxy only toward three regions: NGC7538 IRS1, Sgr B2, and G29.96–0.02. Current efforts by our group using the Very Large Array, Arecibo, and the Green Bank Telescope have resulted in the detection of four new H2CO 6cm maser regions. We discuss the characteristics of the known H2CO masers and the association of H2CO 6cm masers with very young regions of massive star formation. We also review the current ideas on the pumping mechanism for H2CO 6cm masers.

Protease Degradation

Asparaginase (ASNase) is a widely applied chemotherapeutic drug that is used to treat Acute Lymphoblastic Leukemia (ALL); however, immune responses and silent inactivation of the drug often limit its bioavailability. Many strategies have been proposed to overcome these drawbacks, including the development of improved formulations (biobetters), but only two of them are currently on the market. Nano- and micro-encapsulation are some of the most promising and novel approaches to enhance in vivo performance of ASNase, preventing the direct contact of the enzyme with the environment, protecting it from protease degradation, increasing the enzymes catalytic half-life, and in some cases, reducing immunogenicity. This review summarizes the strategies, particularly for ASNase nano- and micro-encapsulation, and their main findings, constraints, and current gaps in the state-of-the-art knowledge. The pros and cons of the use of different nanocarriers are discussed with the idea to ultimately provide safer and more effective treatments for patients with ALL.

Chemical Propulsion

It is not the intention of this Theme Issue to include any discussion of the pros and cons of hypersonic flight; the existence of a large array of man-made satellites, which seems likely to increase rather than decrease, is a clear indication th at hypersonic flight is already with us and likely to stay with us. Since hypersonic speeds are in practice achieved by some form of chemical propulsion, which uses a good deal of fuel, it is im portant to strive for high efficiency. This in turn suggests that airbreathing engines have an important part to play, by avoiding the weight of the oxidant in comparison with rockets, and furthermore that good lift—drag ratios are im portant even for hypersonic vehicles by offering a wide choice of trajectory. It is these considerations that have led to the choice of hypersonic aerodynamics as the theme of this volume

Pros And Cons

Mobile technologies are more and more present in students’ lives. Therefore, it is interesting to see how these technologies enable students to learn beyond their courses. In this paper, the authors describe some ongoing work funded by their institution. The authors are developing a prototype of a project-based learning ubiquitous platform which aims at helping students learn some skills and knowledge about project management. In accordance with project-based learning theories, their platform also teaches students how to collect knowledge and introduces them to lifelong learning skills. The software is designed to be reused and adapted to various situations of ubiquitous and collaborative learning, for universal clients (smartphones, tablets, laptops, PCs, etc.). They have designed the technical architecture of the authors’ platform so as to make it easily extendable and maintainable. The technical and pedagogical evaluation of the authors’ platform has been done with students in real life conditions, during a period dedicated to a project to create innovative business. At the end of the paper, the authors describe this experimentation and discuss the pros and cons of such a platform.

Affected Country

The corona virus are sweeping the world. Transmission that is so fast from human to human causes heavy casualties. Based on research, this virus commonly spread through droplets and direct contact with sufferers. Nowadays, vaccines and drugs are still being developed by experts. Therefore, almost all country take on policies to prevent the spread of the virus. As an affected country, Indonesia also issued a policy of Pembatasan Sosial Sekala Besar (PSBB) (Large-Scale Social Restrictions). This rule regulate various aspects such as restrictions on educational, employment and worship activities. In the rules of worship, this regulation requires temporary abolition of worship in worship place. This instruction raises the pros and cons in society. Some people consider the omission of observance in the worship place is inappropriate due to the fact that other public places such as markets are still open. Using kaidah fikih and ushul fikih approach, this paper analyzes the policy. The results of this study indicate that the policy of eliminating the worship in the worship places during a pandemic is not inapposite with Islamic law. Moreover, to issue other policies in dealing with this pandemic, based on Islamic law, safeguarding lives (hifzh al-nafs) is prioritized more than protecting assets (hifzh al-mâl).

F Ring

ABSTRACTSaturn's broad E ring, the narrow G ring and the structured and apparently time variable F ring(s), contain many micron and sub-micron sized particles, which make up the “visible” component. These rings (or ring systems) are in direct contact with magnetospheric plasma. Fluctuations in the plasma density and/or mean energy, due to magnetospheric and solar wind processes, may induce stochastic charge variations on the dust particles, which in turn lead to an orbit perturbation and spatial diffusion. It is suggested that the extent of the E ring and the braided, kinky structure of certain portions of the F rings as well as possible time variations are a result of plasma induced electromagnetic perturbations and drag forces. The G ring, in this scenario, requires some form of shepherding and should be akin to the F ring in structure. Sputtering of micron-sized dust particles in the E ring by magnetospheric ions yields lifetimes of 102to 104years. This effect as well as the plasma induced transport processes require an active source for the E ring, probably Enceladus.

Vinblastine Sulfate

Earle's L-929 fibroblasts treated with mitosis-arresting but sub-lethal doses of vinblastine sulfate (VLB) show hypertrophy of the granular endoplasmic reticulum and annulate lamellae. Exposure of the cells to heavier doses of vincristine sulfate (VCR), a VLB-related drug, leads to the accumulation of large amounts of helical polyribosomes, Golgi membranes and crystals in the cytoplasm. In many of these cells a large number of helical polyribosomes are arranged in prominent linear rows, some of which may be up to 5 micrometers in length. Figure 1 shows a large array of helical polyribosomes near a crystalline mass (CRS) in an Earle's L-929 fibroblast exposed to VCR (5ϒ/ml.) for 3 hours At a higher magnification, as seen in figure 2, the helical polyribosomes are seen arranged in parallel rows. In favorably cut sections, a prominent backbone like "stalk" of finely granular material, measuring approximately 300Å in width is seen in close association with the linear rows of helical polyribosomes.
