胰島素是一種蛋白質激素，由胰腺中的胰島細胞分泌。 糖尿病患者由於各種因素，血糖異常升高，其病因主要是由於其胰島素活性相對較弱，胰高血糖素活性相對較強，即激素功能障礙。

1型糖尿病的胰島素分泌細胞受到嚴重破壞或完全失活。內源性胰島素分泌極低，需要外源性胰島素和長期注射治療。然而，很多人只知道胰島素注射可以控制糖尿病，卻不知道長期注射胰島素也有很多危害。

i. 長期注射胰島素有什麼危害?

糖尿病患者如需要注射胰島素針，也有可能會受胰島素副作用影響，包括體重上升。

1、長期進行注射胰島素，最常引起的情況分析就是發展導致發生低血糖，症狀較輕的話我們可以直接影響到中國植物通過神經網絡系統，表現為眩暈、饑餓、臉色蒼白、疲勞和出汗等，也有少部分患者可能出現震顫、心前區不適和四肢麻木、頭痛的症狀。當情況不斷加重時，中樞神經信息系統會出現問題障礙，表現出不同發音功能障礙、肌肉震顫、複視、共濟失調，繼而能夠引起驚厥甚至是昏迷，這就是提高胰島素休克。若搶救不及時，可引起死忙。

2，胰島素可以控制血糖，但不能改善身體胰島功能，雖然本身不??是胰島素依賴性，但長時間使用會造成惰性自體胰島功能。

3、長期注射胰島素或經常在我們一個重要位置注射，會造成影響這些不同位置皮下脂肪營養不良。

長期注射胰島素也可能引起過敏，有全身性過敏和局部過敏。全身性過敏可導致尋找麻疹，紫癜，甚至過敏反應，而局部過敏只表現在注射部位和周圍斑丘疹瘙癢等。

Beating the heat in electronics

A nanocomposite continues to be invented by scientists of Rice University’s Brown University of Engineering. The nanocomposite combines one-dimensional polymer nanofibers and two-dimensional boron nitride nanosheets. The nanofibers boost the self-assembling substance though the “white graphene” nanosheets provide a thermally conductive network which allows it to face up to the heat that breaks down widespread dielectrics, the polarized insulators in batteries and other products that independent optimistic and unfavorable electrodes.

The 12-to-15-micron-thick materials functions being an successful heat sink as much as 250 degrees Celsius (482 degrees Fahrenheit), in accordance with the researchers. Tests showed the polymer nanofibers-boron nitride mixture dispersed heat four moments superior in comparison to the polymer by yourself.

In its simplest sort, one layer of polyaramid nanofibers binds by means of van der Waals forces to a sprinkling of boron nitride flakes, 10% by fat with the remaining product or service. The flakes are only dense ample to type a heat-dissipating network that still makes it possible for the composite to retain its versatility, and even foldability, though keeping its robustness. Layering polyaramid and boron nitride might make the fabric thicker when nevertheless retaining overall flexibility, in keeping with the scientists.

Rising Thermal Administration Solutions

So that you can deal with the escalating need to have for much better thermal management, researchers in laboratories all over the world are researching promising new elements and ways to assist in paving how for scaled-down, additional impressive computing and interaction systems.

A heat-absorbing semiconductor

As people demand from customers lesser, more rapidly plus much more powerful electronic gadgets that attract a lot more current and produce additional heat, the problem of warmth administration is reaching a bottleneck. With existing technological innovation, there’s a limit into the sum of heat that can be dissipated from the inside out.

Back in July 2018, UCLA engineers had formulated a semiconductor substance, a defect-free boron arsenide, that’s extra productive at drawing and dissipating squander heat than every other acknowledged semiconductor or metallic materials. In keeping with the researchers, defect-free boron arsenide offers record-high thermal conductivity and is particularly in excess of three-times faster at conducting heat than at this time used materials, these kinds of as silicon carbide and copper. What this means is that heat that may normally focus in hotspots is swiftly swept away.

In 2013, scientists at Boston College and the U.S. Naval Study Laboratory described that boron arsenide could most likely carry out as well as diamonds when applied like a warmth spreader. Diamonds possess the greatest regarded thermal conductivity, all around 2,200 watts for every meter-kelvin, as opposed to about one hundred fifty watts for each meter-kelvin for silicon.

Following up on that discovery, in July 2018, scientists with the University of Texas at Dallas, the University of Illinois at Urbana-Champaign, and also the University of Houston declared they had produced a possible warmth conduction choice that, though not as productive as diamonds, marks a substantial enhancement about silicon.

Polymer thermal conduction

In March 2018, MIT engineers introduced the development of the new plastic materials - a polymer thermal conductor - that capabilities as a warmth conductor, dissipating warmth somewhat than insulating it. The researchers claimed that the new content, which happens to be light-weight and versatile, can perform ten occasions just as much heat as most commercially utilised typical polymers.

On typical, check samples with the new polymer were equipped to carry out warmth at about two W/m/K, somewhere around ten moments a lot quicker than what typical polymers can reach. In checks done for the Argonne Nationwide Laboratory, Xu and co-researcher Zhang Jiang, an Argonne physicist, identified the polymer samples appeared practically isotropic, or uniform. Following this reasoning, the staff predicted the materials should really be able to perform heat similarly perfectly in all instructions, increasing its heat-dissipating probable.

Merging electronics and antennas

By integrating the design of antenna and electronics, Georgia Institute of Technological innovation scientists claim to get found a means to boost the power and spectrum efficiency of the new class of millimeter wave transmitters, allowing improved modulation and minimized waste heat. The end result promises to lead to lengthier chat time and higher facts fees in millimeter wave wireless interaction units designed for upcoming 5G mobile purposes.

Elementary for the new style and design may be the means to maintain a high-energy efficiency irrespective if the product is working at its peak or common output electrical power. The scientists mentioned which the effectiveness of most conventional transmitters is significant only within the peak power but drops significantly at reduced electric power ranges, resulting in minimal performance when amplifying complicated spectrally effective modulations. Moreover, conventional transmitters often add the outputs from many electronics employing lossy energy combiner circuits, exacerbating the efficiency degradation.
