This paper represents IOT Based Automatic Water Temperature Adjustor. IoT (Internet of Things) refers to the network of physical objects that are embedded with sensors, software, and other technologies for the purpose of connecting and exchanging data with other devices and systems over the internet. This system is for adjusting water temperature according to the possible surroundings such as home temperature, atmosphere temperature, etc. To solve problems like high water temperature while using, time-consuming waiting for water to heat and cool, high power consumption, and not satisfying water temperature this system offers the feature for automatically adjusting the temperature. Arduino, DHT11 (Temperature-Humidity Sensor), Bread Board, DS18B20 (Water Temperature Sensor), Jumper Wires, Resistor, I2C OLED, Water Heating Coil, Relay and LED are used for operating this system. The application of this system is very vast as it can be implemented in power plants, hospitals, mountain regions, local homes, and lodges. This system is time-saving, cost-efficient, easy to implement, provide automatic features, less power consumption, safety, and many more. Compared to other water geyser systems it has the feature of automatically detecting the environmental temperature and adjusting the temperature of the water accordingly. This system is still in its developing phase.

This work is devoted to solving the problem of orientation in the space of visually impaired people. Working on the project, a new way of transmitting visual information through an acoustic channel was invented. In addition, was developed the device, which uses distance sensors to analyze the situation around a user. Thanks to the invented algorithm of transformation of the information about the position of the obstacle into the sound of a certain tone and intensity, this device allows the user to transmit subject-spatial information in real time. Currently, the device should use a facette locator made of 36 ultrasonic locators grouped in 12 sectors by the azimuth and 3 spatial cones by the angle. Data obtained in such a way is converted into its own note according to the following pattern : the angle of the place corresponds to octave, the azimuth corresponds to the note and the distance corresponds to the volume. The choice of the notes is not unambiguous. However, we used them for the reason that over the centuries, notes have had a felicitous way of layout on the frequency range and on the logarithmic scale. Therefore, the appearance of a new note in the total signal will not be muffled by a combination of other notes. Consequently, a blind person, moving around the room with the help of the tone and volume of the sound signals, will be able to assess the presence and location of all dangerous obstacles. After theoretical substantiation of the hypothesis and analysis of the available information, we started the production of prototypes of the devices that would implement the idea of transmitting information via the acoustic channel.

The lack of drinking water in human settlements triggers a series of problems that are linked and affect the development of humanity: health problems, lack of water security for companies, lack of jobs, insecurity, among others. We observe this problem in the communities of the municipality of Las Vigas de Ramírez, Veracruz, where there is a great problem with the water supply, although there is a high presence of mist. Faced with this situation, we undertook the task of investigating a water harvesting method that is easy to implement, operate and maintain. We investigated and analyzed the methods of mist condensation through physical barriers, finding that the polyethylene shadow mesh was the means to achieve this, because it allows the passage of the wind, it is very light, easy to manipulate and above all that it presents the phenomenon of percolation that allows water droplets of various diameters to be accommodated therein. We designed a device that allows to present a mist catchment area through a prismatic structure enabled with meshes and condensed water receivers, portable, easy to use and maintenance and very economical with a performance of 20 liters per day. To achieve our project, factors such as air humidity, dew point, wind speed and direction, height, temperatures and available spaces must be considered.

In this project, we evaluate the effectiveness of Random Shuffling in the Cross Lingual Information Retrieval (CLIR) process. We extended the monolingual Word2Vec model to a multilingual one via the random shuffling process. We then evaluate the cross-lingual word embeddings (CLE) in terms of retrieving parallel sentences, whereby the query sentence is in a source language and the parallel sentence is in some targeted language. Our experiments on three language pairs showed that models trained on a randomly shuffled dataset outperforms randomly initialized word embeddings substantially despite its simplicity. We also explored Smart Shuffling, a more sophisticated CLIR technique which makes use of word alignment and bilingual dictionaries to guide the shuffling process, making preliminary comparisons between the two. Due to the complexity of the implementation and unavailability of open source codes, we defer experimental comparisons to future work.

溫熱化學治療(Hyperthermic Intraperitoneal Chemotherapy, 簡稱HIPEC)，為將化療藥物加熱後灌注到腹腔內殺死癌細胞，但溫熱化學治療只能在開刀時使用，治療次數有限。為達到多次的熱化療效果，本研究開發奈米氧化鐵藥物磁性複合微粒(Nano iron oxide magnetic drug complex particles, NIOMP)，可利用開刀時包覆複合微粒於腹腔，術後用磁場加熱，加上微粒化療藥物釋放，達到多次溫熱化學治療。NIOMP以鐵氧化物奈米粒子為核心，海藻酸鈉為外殼體，利用電紡法將前其與氯化鈣交聯產生凝聚性微粒。數據顯示最佳製作條件為16 kv高電壓、距離4 cm、噴速5μm/s，可得直徑大小約為200~450 μm穩定性高微粒。藥物釋放實驗顯示，NIOMP於2~7小時藥物釋放速率較穩定。利用可變磁場之電磁效應加熱NIOMP中氧化鐵磁顆粒，可於30分鐘內快速升溫至43℃。細胞相容性測試結果得知，NIOMP對細胞無毒性。本研究改善HIPEC的治療限制，可多次針對腫瘤患部局部熱化學治療，未來將可改善病人存活率。

缺氧（Hypoxia）在癌症中，影響腫瘤微環境（Tumor microenvironment，TME）的重塑扮演重要的角色。原位癌細胞與欲轉移之遠端器官的微環境間，會透過細胞外囊泡（extracellular vesicles，EVs）進行細胞間相互作用，對於轉移前腫瘤微環境（Pre-metastatic niche，PMN）的形成和轉移過程至關重要。 本研究目的在闡明缺氧條件下，肺腺癌如何透過產生的外囊泡重塑肝臟轉移前微環境。結果顯示缺氧刺激肺癌產生的細胞外泌體（Exosome）增加了肝臟星狀細胞（hepatic stellate cell，HSC）活化和血管生成。由於缺氧肺癌所分泌的EVs含有CD151蛋白，促進HSC的活化和血管新生。缺氧肺癌所產生的Exosome增 加了HSC和內皮細胞中FAK（focal adhesion kinase）、Src（SRC proto-oncogene, non-receptor tyrosine kinase）和AKT（AKT serine/threonine kinase）通路的激活。 總結此實驗證實了缺氧腫瘤衍生的Exosomes，探討其中富含的CD151機制，活化了HSC與特別的訊息傳遞於細胞中，調節肝臟PMN的形成。因此CD151可作為肺腺癌轉移至肝臟的新治療靶點。

Introduction: Using advanced technologies such as nanotechnology in the food and fishery industry, as one of the most important industrial sectors of countries, has received too much attention. Traditionally, fishing and hunting have been considered important sources of supplying food. The subject and methodology: The study aims to investigate nanotechnology for detecting fish hatching time. This is a review article that collects the information from databases such as Sid, civilica, and Google Scholar. In the end, 22 papers were studied for extracting and collecting the required information from the abovementioned scientific database. Finding: After examining the food, drug, and agricultural-related papers published from 2009 to 2020, it was concluded that small Nano-sensors, controlling & monitoring systems made from nanotechnology can be installed on fishing nets, fishing rods, and other fishing equipment. These devices (Nano-sensors and controlling & monitoring systems) will help fishes so that they don’t get caught. In this way, as a fish gets close to the fishing equipment, it will receive sound, smell, or heat-based alarm. Therefore, the fish will stay away from the fishing equipment. The result: according to the finding of this study, it can be concluded that excessive fishing in the hatching time will be avoided by the application of nanotechnology in the fishing equipment. As a result, the following advantages will be secured: 1- There are lots of opportunists who misuse fish during the hatching time. With the application of nanotechnology, they will be stopped. 2- Opportunists are ambushing in different time points to misuse fish. Also, the guards might be ignorant. With the application of nanotechnology, guards are no longer required. 3- This plant is cost-effective too.

Microplastics are tiny invisible plastic pieces that are piling up in the marine environment emerging as one of the many environmental issues which our planet is facing today. Researches for the removal of these particles are important because studies that have been made so far haven't come up with an effective solution. This project aimed to detect microplastics and remove them from aqueous environments with an effective and practical method then it was aimed to determine the removal amount of microplastics by optical measurements with the developed system. Firstly, the magnetic carbonanotubes (m-CNT) which is intended to hold onto the surfaces of microplastics was synthesized and added to the mixture of microplastics. Then the magnet within a glass tube was passed through the mixture and the sample was cleared of microplastics. A spectrometer was made to monitor this process and after its calibration, it was used to measure coffees with different concentrations. It has been shown that their concentrations can be determined by calculating the transmission values and Rayleigh scattering. In the end, it has shown that there are no micro or nano-sized plastic particles when removed with M-CNT, within the accountable range of the spectrometer that had been made. Hence the removal of the microplastics: an invisible threat for the environment has been studied by combining nanomaterials with unique surface properties in the removal process and an optical principle such as Rayleigh scattering, a new technique has been developed that can measure quickly, economically,

在歐氏幾何和射影幾何中，相異五點可決定一圓錐曲線。若給定任意四邊形，是由四邊形的四個頂點及異於此四頂點的第五點來決定圓錐曲線，則稱此四邊形為圓錐曲線内接四邊形。 圓冪定理是一個圓內接四邊形的幾何定理，包含相交弦定理、割線定理、切割線定理等三個定理，我們將圓冪定理推廣至圓錐曲線內接四邊形。首先由圓錐截痕推廣圓內兩交弦定理，是考慮兩垂直交弦，進而推導出圓冪定理推廣一式及區分圓錐曲線種類。接著利用圓錐曲線的方向直徑、邊或對角線斜率及平行邊的切線長推導出圓冪定理推廣二式、三式及四式，推廣式是採統一與歸納方式呈現。 其次，由解析幾何推導另一種圓冪定理推廣式(推廣五式)，加上圓錐曲線直徑性質，論證出二種圓錐曲線及其内接四邊形的作圖及其判定條件。最後也證明圓錐曲線內接四邊形判定定理及有趣的錐線中心軌跡圖形。
