The Meaning Function of the Case Particle ʃi in the Tsuken Island Dialect of Japanese Considered from the Perspective of Collocative Relations

This paper describes the case particle ʃi in the Tsuken Island dialectČlanek predstavlja členek ʃi v narečju otoka Tsuken (Okinawa, Japonska), ki ima podobno funkcijo kot predlog to v angleščini. Domnevno gre za ustreznik členkov ni ali e v knjižni japonščini, vendar njegov izvor ni povsem jasen. ʃi nima le funkcije ni ali e, temveč tudi eno izmed funkcij made knjižne japonščine. Zdi se, da se je ʃi razvil v narečju otoka Tsuken. of Okinawa, Japan. This particle has a similar function to the preposition to in the English language. It is thought that ʃi is equivalent to case particles ni or e in the Japanese standard language, but its origin is not clear. ʃi has not only the function of ni or e, but also one of the functions of Standard Japanese made. It seems that ʃi developed in the Tsuken Island dialect

Development of the Micro Pixel Chamber with resistive electrodes

We developed a novel design of a Micro Pixel Chamber ($\mu$-PIC) with resistive electrodes for a charged-particle-tracking detector in high-rate applications. Diamond-Like Carbon (DLC) thin film is used for the cathodes. The resistivity can be controlled flexibly ($\mathrm{10^{5-7}k\Omega/sq.}$) at high uniformity. The fabrication-process was greatly improved and the resistive $\mu$-PIC could be operated at 10$\times$10 $\mathrm{cm^2}$. Resistors for the HV bias and capacitors for the AC coupling were completely removed by applying PCB and carbon-sputtering techniques, and the resistive $\mu$-PIC became a very compact detector. The performances of our new resistive $\mu$-PIC were measured in various ways. Consequently, it was possible to attain high gas gains ($\mathrm{> 10^{4}}$), high detection efficiency, and position resolution exceeding 100 $\mu$m. The spark current was suppressed, and the new resistive $\mu$-PIC was operated stably under fast-neutrons irradiation. These features offer solutions for a charged-particle-tracking detector in future high-rate applications.Comment: 37pages, 40figures, To be submitted to Nucl. Instrum. Methods Phys. Res.

Validation of CFD Codes for the Helicopter Wake in Ground Effect

When a helicopter takes off, lands, or makes hovering or taxiing flights in ground effect, its downwash interferes with the ground. Encounters with such highly turbulent helicopter wakes have been blamed for two fixed-wing aircraft crashes in the United Kingdom. Additional incidents including tents blown away are reported in Japan. Due to these accidents, the Japan Aerospace Exploration Agency (JAXA) and the University of Glasgow (UoG) are investigating the helicopter wake structure in ground effect, especially during taxiing, by means of computational fluid dynamics (CFD). In this study, CFD codes of UoG and JAXA are validated through comparing numerical results of each party and flight experiment data. As a result, it is found that the CFD codes show qualitatively the same results each other and they are also close to the experiment

Parasitoids and Predators of Insect Pests on Chrysanthemums in Hawaii

Trials were conducted at a commercial cut-chrysanthemum nursery in Mountain View, Hawaii to evaluate biological control of chrysanthemum insect pests. No chemical pesticides were applied throughout the growing season. Numerous parasitoids and predators of the agromyzid leafminer, Liriomyza trifolii (Burgess), the green peach aphid (GPA), Myzus persicae (Sulzer), and the variegated cutworm (VC), Peridroma saucia (Hubner), were recovered. The two dominant parasitoid species of L. trifolii, Diglyphus intermedius (Girault), and Ganaspidium utilis Beardsley, provided biological control during the first 7 to 9 weeks after planting when the unmarketed portion of the chrysanthemum foliage was growing. Additional biorational or chemical control methods are necessary for GPA. VC, and L. trifolii when their damage affects the marketable portion of the crop

Primary Mucinous Adenocarcinoma of the Testis

Ovarian-type surface epithelial neoplasms of the testis and paratestis are uncommon, and the mucinous subtype is particularly rare. These tumors represent a counterpart to ovarian cancer. Malignant tumors have the potential for metastatic spread and are often fatal. The case of a 59-year-old man with testicular mucinous adenocarcinoma is presented. Computed tomography indicated involvement of the paraaortic and pelvic lymph nodes, so chemotherapy was initiated. To the best of our knowledge, this is the second paper regarding responsiveness to chemotherapies used in ovarian cancer

Case study: Lead contamination in soil and plants of a Metro Atlanta home

INTRODUCTION: Lead contamination in housing developments of the Metro Atlanta Area has prompted the US Environmental Protection Agency (EPA) to establish the Westside Lead Superfund Site for soil and plant remediation efforts. As a result, affected residents have to review their own health and wellness in a different perspective due to the possibility of having lead contamination. No quantity of lead is considered safe in the human body, especially since it is known to compete with the functionality of calcium in many vital biological processes. Manufacturing and disposal procedures in lead-based industries have contributed to lead contamination of soil and water. This especially occurs along railroads where historic operations involved the transport of industrial products containing heavy metals. These transportation routes are found to have elevated levels of heavy metals due to normal train operations, but in some cases the practice of dumping waste into a railroad’s easement has created areas of significant lead contamination. It is possible for these past railroad easements to transition into residential areas, which is the case for one Metro Atlanta home north of the Westside Atlanta Superfund site. Testing of this residence found significant levels of lead contamination, especially where they grew their own produce. Due to the elevated concentration of lead, the EPA has reported to this resident that removal of the soil is recommended. OBJECTIVES: The goal of this study is to conduct soil and plant sample analysis for lead contamination in a Metro Atlanta residence to observe for possible lead propagation into plants in partnership with the Saikawa Lab of Emory University. METHODS: Soil and plant samples are collected and prepared for evaluation of lead contamination through inductively coupled plasma mass spectrometry (ICP-MS). Lead naturally occurs in soil with an average geologic concentration of 10-30 ppm. If levels exceed the average geologic concentration, caution should be considered because it indicates that lead was added by exogenous sources. The lead soil screening level (SSL) of 400 ppm represents the conservative estimate by the EPA as a level of contamination considered a public health issue. The EPA recommends the removal of the lead contaminated soil if levels exceed the lead SSL. RESULTS: The results obtained in this study will be utilized to understand lead’s propagation into plants from lead contaminated soil. Sample processing is still under way. Data will be compared to preliminary lead contamination testing performed by the EPA, which showed a range of soil lead levels from 348 to 654 ppm in the areas where the resident planted their produce. CONCLUSION: Food scarcity relative to the COVID-19 pandemic and the following inflation on produce has led many to start home or community gardens. Increasing awareness on the risks of planting in areas without heavy metal evaluation is paramount for the future of those wishing to grow produce safely in their own backyard
