Direct Tensile Strength of Steel Fiber Reinforced Concrete by Using Clamping Grips

This report presents the tensile strength behavior of steel fiber reinforced concrete (SFRC). In this experimental work, direct tensile test by using clamping grips is carried out for the prismatic mortar and concrete specimens reinforced with steel fibers. The volume content of steel fibers varies from 1.0 percent to 2.0 percent of the concrete volume. Test results for different fiber content, fiber length, and specimen size are presented. The results are compared with the results of indirect tensile strength by splitting cylinder method

Temperature Distribution Analysis of Concrete in Fill Dam Gallery

In this paper, the thermal behaviour in concrete of an inspection gallery during construction is analyzed using the finite element method. The temperature changes due to hydration heat of cement and the effects of pipe cooling on the temperature distribution in the concrete are discussed from the analytical results

Endogenous reference RNAs for microRNA quantitation in formalin-fixed, paraffin-embedded lymph node tissue

Lymph node metastasis is one of the most important factors for tumor dissemination. Quantifying microRNA (miRNA) expression using real-time PCR in formalin-fixed, paraffin-embedded (FFPE) lymph node can provide valuable information regarding the biological research for cancer metastasis. However, a universal endogenous reference gene has not been identified in FFPE lymph node. This study aimed to identify suitable endogenous reference genes for miRNA expression analysis in FFPE lymph node. FFPE lymph nodes were obtained from 41 metastatic cancer and from 16 non-cancerous tissues. We selected 10 miRNAs as endogenous reference gene candidates using the global mean method. The stability of candidate genes was assessed by the following four statistical tools: BestKeeper, geNorm, NormFinder, and the comparative ΔCt method. miR-103a was the most stable gene among candidate genes. However, the use of a single miR-103a was not recommended because its stability value exceeded the reference value. Thus, we combined stable genes and investigated the stability and the effect of gene normalization. The combination of miR-24, miR-103a, and let-7a was identified as one of the most stable sets of endogenous reference genes for normalization in FFPE lymph node. This study may provide a basis for miRNA expression analysis in FFPE lymph node tissue

Lymphoplasmacytic Lymphoma Presenting with Diarrhea and Joint Pain Which was Successfully Diagnosed by an MYD88 Mutation Analysis

A 55-year-old man presented to our department with diarrhea, weight loss, fatigability, and polyarthralgia. Blood tests revealed elevated soluble interleukin-2 receptor levels and IgG-type M protein positivity, without any findings that were suggestive of collagen disease. After computed tomography (CT) detected enlarged lymph nodes in the abdominal para-aortic region, lymphoma was suspected. CT-guided needle biopsy of the lymph node did not help to achieve a definitive diagnosis; however, a bone marrow test showed the pathological features of B-cell lymphoma. A genetic examination detected a MYD88 L265P mutation; the mutation analysis was valuable in diagnosing lymphoplasmacytic lymphoma in a IgM-type M protein-negative patient

More than the “Wife Corps”: Female Tenant Farmer Struggle in 1920s Japan

AbstractStruggles over social reproduction intensified and took on new forms in Japan during the interwar period, as the state found it increasingly difficult to secure the foundations for the continued accumulation of capital. Landlord-tenant disputes that erupted nationwide in the midst of Japan's post-World War I agricultural recession was one concrete manifestation of these struggles. While the significance of tenant disputes has been analyzed in great detail by scholars, there has been a surprising lack of historical scholarship on the role that female tenant farmers played within them. This absence is a manifestation of two tendencies: First, gendered assumptions surrounding the figure of the tenant farmer have led scholars of agrarian social movements to work from a relatively limited understanding of what constitutes struggle and by extension, who its protagonists have been. Second, the conflation of waged work as productive work and by extension, non-waged work as unproductive has unwittingly relegated many forms of struggle that working women participated in to the realm of the pre-political. This paper contends that far from being mere supporters – the wife corps – of what was ultimately a male-driven movement, female participants in tenant disputes produced their own powerful critiques of the way that the Japanese state and capital undervalued their lives and labor. As such, they should be understood as one link in a rich history of proletarian feminist struggle both within and outside of the Japanese empire

RADIOGRAPHIC OBSERVATION OF RAPID EXPANSION OF HUMAN MAXILLA

An attempt was made to study the process of the separation of the human mid palatal suture by rapid expansion and the subsequent restorative changes. Fixed type orthodontic plates with expansion screws were inserted into eight orthodontic cases with the lateral compression of the maxilla. The amount of the expansion was measured on the occlusal x-ray pictures and the restorative process was observed. The conclusions are summarized as follows: 1. The mid-palatal suture could be separated to some extent in the palatal bone area. 2. The restorative process started by the spicule formation and the ossification were completed two months later. 3. The intra-alveolar changes of the anchor teeth did not exceed the amount of the separation a t the mid-palatal suture. 4. The increase of SNA and the decrease of SNB were dominantly observed, resulting in the significant increase of ANB. 5. No distinct information on the effective age for the application of the rapid expansion could be obtained. 6. The rapid expansion should be an effective method of practical orthodontics to reduce the skeletal deficiency such as the lateral compression of the maxilla as well as the functional interference resulting from the skeletal deficiency
