A STUDY ON TRADITIONAL ARCHITECTURE IN ITANAGAR CAPITAL COMPLEX AND TO IMPROVE A MODIFIED TYPOLOGY FOR A CLIMATE RESPONSIVE CONTEMPORY HOUSE

The lifestyle of the Arunachal Pradesh rural population demonstrates the example of sustainable living where bamboo plays a major role. Bamboo has its home in this tropical climate region of India. In order to understand various aspects of traditional bamboo constructions, a field visit was made to Rono, Emchi, Lekhi villages and Karsingsa, Pachin, NEEPCO areas. The paper studies the patterns affecting the housing styles of these regions, the traditional method of construction including bamboo treatments. Various parameters which are required to be considered for constructing a house are also studied. It has been found in the field survey that the utilization of bamboo is mostly in wall panels, columns, floor, door and windows. The question posed here is whether tradition houses perform better than a typical contemporary house in creating comfortable internal conditions. And if they do how it is possible for the contemporary house to benefit from the advantages presented in the design of the traditional house in terms of thermal performance. The results indicate that improved performance might be achieved by combining selected lessons from the traditional design e.g. improved shading, regional variations in window size related to orientation and adoption of adjustable ventilation and window openings.

內皮素對稻田魚(Oryzias latipes)胚胎適應酸環境之調節

哺乳類的內皮素(endothelin-1 ; EDN1)與其受體endothelin receptor B己知可共同參與腎臟排酸功能之調節,在魚類的表現上,亦有研究指出EDN1會影響到斑馬魚的排酸。本研究中以廣鹽性魚種稻田魚(Oryzias latipes)仔魚為實驗對象,經6小時以上時間酸處理後其體表排酸量皆顯著增強,且經6小時酸處理後,仔魚rhcg1及內皮素受體EDNRA2的基因表現量也顯著增加,並發現當弱化(knockdown)仔魚的endothelin-1基因後,其體表排酸量顯著下降,證實endothelin-1對仔魚排酸作用有直接的影響。而當仔魚endothelin-1的基因表現被抑制後,其離子細胞密度以及離子通道蛋白基因表現不受影響,推測內皮素並非以增加離子細胞的方式影響排酸,而是藉由轉譯後調控途徑,使其排酸功能增強。另外本研究中再將6小時及7天酸處理實驗結果比對後,推測當稻田魚仔魚面臨短期或長期酸環境刺激時,內皮素調節機制亦略有不同。

The change in NaCl crystals from cubic to octahedral~Sodium polyacrylate stabilizes the {111} face of Miller indices~

When adding 2% or 4% sodium polyacrylate as habit modifier, standard milky-white octahedral NaCl crystals grew gradually in saturated NaCl solution on the bottom of the container. [1] [2] Sodium polyacrylate is well known as a highly water-absorbable polymer with many carboxylate anions. In the case of low concentration (0.01%, 0.02%, 0.05%, 0.1% and 0.5%) sodium polyacrylate many small or microscopic crystals whose shapes were nearly octahedrons and had {111} faces were observed with an optical microscope on the bottoms of the solution containers. In low concentration sodium polyacrylate, octahedral NaCl crystals made up of electrostatically unstable {111} faces grew similarly to crystals in high concentrations of 2% or 4% NaCl. Therefore, by adding sodium polyacrylate to saturated NaCl solution, cleaved rock salt crystals in this sol were observed to find out whether or not a change in crystal morphology from cuboids of {100} faces to octahedrons of {111} faces would occur. Regardless of the sodium polyacrylate concentrations of 0.01%, 0.02%, 0.05%, 0.1%, 0.5% and 2%, all cuboid crystals changed into a pyramidal shape in which four of the side surfaces formed an equilateral triangle. When one side of each equilateral triangle face was rotated so the square face of the crystal was soaked in the NaCl sol, all crystals grew into octahedrons of high transparency. Sodium polyacrylate, even under a low concentration, caused morphological change in the NaCl crystals. Many carboxylate anions in the sodium polyacrylate attracted sodium ions and the repulsive force between the carboxylate anions became weak, excluding the water in the internal space of the polymer. We considered that the stabilizing {111} faces of gathered sodium ions attached to carboxylate anions. Chloride and sodium ions coordinated continuously to minimize the NaCl surface area, growing into an octahedral and lowering the surface energy of the NaCl crystal. [3]

A deep learning-based home safety perception system for household service robot

In 2016, the population of people over the age of 65 in Macau was 11.2%. This means that Macau has already become an aging society. As such, more younger generations are needed to look after the elderly. According to statistics, falls are the primary cause of injury or death for the elderly over 65 years old. About 30% of the elderly over 65 years old fall every year. Along with the increase in the elderly population, it is urgent to find a fast and effective way to ensure the safety of the elderly. As there is a lot more danger besides falling in an elderly life, we aim to build a robot collocated with its danger detection system to ensure the safety of the elderly at home. The reason we decided to use robots is that we want to have larger flexibility and mobility, for example, we can give elderly rescue materials when they need help. Moreover, more home robots will be used in the future, they can just apply our system to theirs and ensure the safety of elderlies. In this research, we mainly used cameras with the Openpose model to detect dangers such as falling, potential human action danger, and environmental danger. Innovative ways are used to detect fall action, collocated with our home robot, it is a foreseeing project that could ensure the safety of the elderly in a home environment.

A 100% Solar Electric Vehicle: Applying high efficiency solar modules in sustainable transport

As our planet suffers the effects of climate change, it is only a matter of time before society will have to centre all aspects of development around sustainability. In the past, clean solutions for transportation have been dismissed due to the higher cost, and lower efficiency than fossil fuels. However, in the past few decades, there has been a steep decline in solar module cost, and and a steady climb towards higher efficiency. From my findings in this project, I have concluded that we are now at a point where we can embrace the clean, renewable potential which our sun offers. I have created and tested a proof-of concept electric vehicle (Solar EV), which can run indefinitely during daylight hours, provided sunny conditions. There are several mechanical features of my project which highlight the potential that renewable energy in transportation can have. Firstly the vehicle’s 500W motor is powered by 3 100W solar modules, and 3 50W modules, for a total of 450W or power generation. This means that when driving at anything less than 90% throttle, the Solar EV can run continuously without needing to stop to charge or refuel. Another design mechanism installed in the vehicle are three 12V lead acid batteries. These batteries allow the Solar EV to be powered for over 1.5 hours, which is useful during cloudy conditions, night, and most importantly, when driving through areas of shade. A unique efficiency component designed into my vehicle is the linear actuator I installed into the module racking system. This design element allows the tilt of the modules to be altered, to maximize the efficiency of the solar module array. At early or late hours of the day, it can be heavily tilted with the press toggle switch, or kept at a relatively flat level when the sun is the highest in the sky. I ran a series of trials to figure out whether or not the theoretical data matches up with the experimental results. After my series of trials, the bike was yet to run out of power. The solar vehicle reaches speeds up to 32 km/h, however comfortably glides at around 25 km/h. The linear actuator I installed allows the solar modules’ tilt to change . During different times of day or year, the sun is at different heights in the sky, however it is very important to maximize the solar potential. With the press of a switch, the module can be actuated to account for this. Lastly, regenerative braking captures the energy from braking. Using the reversible nature of a DC motor with a specialized motor controller responding to feedback from the brake actuators allows the vehicle to reuse energy that would otherwise be wasted as heat.

Absorption of Sr2+ at low concentrations using C.moniliferum-- With the aim of practical use of contaminated water processing of the Fukushima Daiichi Nuclear Power Station

We are conducting research for the purpose of treating contaminated water generated by the nuclear accident with C.moliniferum. In previous research, the school seniors examined whether there is a difference in absorption by changing the wavelength of the LED to establish efficient Sr2+ absorption conditions. As a result, the red wavelength was found to be effective for the efficient Sr2+ absorption of C. moniliferum. Therefore, in this study, in order to verify how much Sr is actually absorbed into the cell, the amount of Sr absorption using an atomic absorption photometer is quantified, and the previous research has shown that red is effective for the efficient Sr2+ absorption. The wavelength was considered to be effective because of photosynthesis, and was observed with a scanning electron microscope (SEM) using the photosynthesis inhibitor (DCMU). As a result, it was clarified that C. moniliferum absorbs Sr intracellularly, and photosynthesis was related to absorption.

上皮細胞黏著分子(EpCAM)促進大腸癌細胞中對於艾瑞莎(Gefitinib)之抗藥性研究 EpCAM enhances Gefitinib-induced drug resistance in colon cancer cells

上皮生長因子受體 (EGFR) 已被確認在人類上皮惡性腫瘤扮演重要角色,因此臨床上開發出許多針對EGFR之大腸癌、肺癌等的小分子標靶藥物,但治療期間所產生的抗藥性仍是一大瓶頸。 過去上皮細胞黏著分子(EpCAM)只被認為是胞間連接分子,現今則在癌幹細胞 (cancer stem cells,CSCs)等領域被研究。然而從文獻與先前實驗室的試驗,可以看見EpCAM促進癌症抗藥性的可能。 本研究發現在大腸癌中,艾瑞莎 (Gefitinib) 會透過轉錄因子FOXO3a促進細胞凋亡,而EpEX會經由抑制FOXO3a所促進的凋亡路徑,導致癌細胞產生Gefitinib抗藥性,且此抗藥性,也與EpICD下游之誘導性多能幹細胞相關基因 ( iPS-related genes )的表現有關,但其分子機制尚不清楚。 本研究以大腸癌與Gefitinib做為癌症與EGFR小分子藥物的模型,找出EpCAM可能造成的抗藥路徑,未來可應用在各類癌症之聯合治療 (Combination therapy) ,以克服癌症治療所產生的EGFR小分子藥物抗藥性。
