Control system for suppression of boom or arm oscillation

A control for a working apparatus having a boom arm. The apparatus includes a controller operable to receive signals from at least one pressure sensor. The at least one pressure sensor detects pressure of hydraulic fluid in at least one chamber of a control valve. The controller compares the signals from the at least one pressure sensor to parameters generated by testing the working apparatus. The controller predicts boom arm oscillations based on the comparison of the signals with the parameters, and generates a control signal in response to predicting the boom arm oscillations.https://digitalcommons.mtu.edu/patents/1035/thumbnail.jp

Resource Recycling and Mineral Processing in Korea

In the past few decades the major research activities in mineral processing has shifted from the traditional indust-rialized countries to various mineral producing countries such as India, South Africa, Australia, Chile, and China. The mineral processing research communities in Kbrea have faced a unique problem. The country is small (220,000 km2) and highly populated (70 million). For its sustained economic growth, the tenth world largest economy in the South Korea alone has imported virtually all of its requi-rements in mineral and energy resources. With the improv-ement of the living standard of the people, massive const-ruction of housing, roads, subways, and other social overhead capitals has helped the booming economic cycle. As one of the Tokyo Protocol countries, the reduction in CO2 production has become a big concern for the nation

An Advanced Glycation End Product (AGE)-Receptor for AGEs (RAGE) Axis Restores Adipogenic Potential of Senescent Preadipocytes through Modulation of p53 Protein Function

The impaired adipogenic potential of senescent preadipocytes is a hallmark of adipose aging and aging-related adipose dysfunction. Although advanced glycation end products (AGEs) derived from both foods and endogenous nonenzymatic glycation and AGE-associated signaling pathways are known to play a key role in aging and its related diseases, the role of AGEs in adipose aging remains elusive. We show a novel pro-adipogenic function of AGEs in replicative senescent preadipocytes and mouse embryonic fibroblasts, as well as primary preadipocytes isolated from aged mice. Using glycated bovine serum albumin (BSA) as a model protein of AGEs, we found that glycated BSA restores the impaired adipogenic potential of senescent preadipocytes in vitro and ex vivo. However, glycated BSA showed no effect on adipogenesis in nonsenescent preadipocytes. The AGE-induced receptor for AGE (RAGE) expression is required for the pro-adipogenic function of AGEs in senescent preadipocytes. RAGE is required for impairment of p53 expression and p53 function in regulating p21 expression in senescent preadipocytes. We also observed a direct binding between RAGE and p53 in senescent preadipocytes. Taken together, our findings reveal a novel pro-adipogenic function of the AGE-RAGE axis in p53-regulated adipogenesis of senescent preadipocytes, providing new insights into aging-dependent adiposity by diet-driven and/or endogenous glycated proteins

Luminance enhancement of electroluminescent devices using highly dielectric UV-curable polymer and oxide nanoparticle composite

A flexible hybrid structure electroluminescent (HSEL) device was fabricated from ZnS:Cu phosphor microparticles dispersed in a UVcurable polymer matrix. We observed a maximum luminance of 111 cd/m2 at 10 kHz and 170 V from a device wherein the mixing ratio between the phosphor particles and highly dielectric polymer binder was 70:30 wt%. Furthermore, by uniformly dispersing highly dielectric BaTiO3 nanoparticles within the polymer matrix, we were able to obtain a luminance of up to 211 cd/m2 in the HSEL device. Compared to the conventional thermal curing process, this UV process greatly simplifies the fabrication steps by combining phosphors and dielectric materials at room temperature. This process also demonstrates a promising pathway toward creating flexible and printed EL devices in the future. © 2014 Optical Society of America.1

Surgical Treatment of Inferior Vena Cava Invasion in Patients with Renal Pelvis Transitional Cell Carcinoma by Use of Human Cadaveric Aorta

We herein report a case of radical nephroureterectomy and replacement of the inferior vena cava (IVC) with ahuman cadaveric aortic graft for a patient with renal pelvis transitional cell carcinoma associated with IVC infiltration. In advanced disease, radical surgery is essential to achieve long-term survival. This case entails the use of another treatment option among the numerous options currently available for the management of patients with advanced renal cancer associated with IVC invasion

CT and MR Imaging of the Buccal Space: Normal Anatomy and Abnormalities

The buccal space is an anatomical compartment lying anterior to the masticator space and lateral to the buccinator muscle. Since the major purpose of imaging is to define the likely anatomic origin and also the extent of a given lesion, thorough knowledge of the normal anatomy of the buccal space is essential, and this knowledge can aid the physician in narrowing down the list of possible maladies on the differential diagnosis. We illustrate here in this paper the important anatomic landmarks and typical pathologic conditions of the buccal space such as the developmental lesions and the neoplastic lesions. Knowledge of the expected pathologic conditions is useful for the radiologist when interpreting facial CT and MR images

Development of Korean Academy of Medical Sciences Guideline on the Skin and Related System: Impairment Evaluation of Disfigurement in Skin and Appearance

The purpose of this study is to develop new standards for the disability evaluation with reference to existing laws and other study reports regarding disabilities for the rational evaluation of the diverse kinds of disfigurement in appearance and skin. Three plastic surgery specialists and 3 dermatology specialists developed a new standard for the disability evaluation which is appropriate for circumstances in Korea. Disability rate does not take into account the social occupation, gender or age of the patient, but instead, evaluate the Activity of Daily Living and the social adaptability of the appearance and skin disfigurement regardless of the balance between different disabilities. We tried to include most cutaneous disorders and categorized them into 3 types; congenital (Type 1), acquired (Type 2) as well as any permanent skin impairment sequelae of disease, trauma or treatment process (Type 3). For type 3 disorders, we tried to rate the score according to the size of involved skin lesion. The disability rate is determined by dividing the disability class into 8 steps based on the seriousness of each type of disability

A Case of Noncompaction of the Ventricular Myocardium Combined with Situs Ambiguous with Polysplenia

A 33-year-old man was admitted to our hospital with chest pain and exertional dyspnea. Two-dimensional echocardiography showed prominent trabeculations and deep intertrabecular recesses, findings consistent with noncompaction of the ventricular myocardium. Thoracoabdominal CT and cardiac magnetic resonance imaging (CMR) revealed situs ambiguous with polysplenia and noncompaction of the left ventricular myocardium. CMR also demonstrated delayed enhancement of the trabeculations located at the apical portion of the left ventricle. The coronary angiogram was normal. This is the first case of noncompaction of the ventricular myocardium associated with situs ambiguous with polysplenia
