The Physics of Bodily Tides in Terrestrial Planets, and the Appropriate Scales of Dynamical Evolution

Any model of tides is based on a specific hypothesis of how lagging depends on the tidal-flexure frequency. For example, Gerstenkorn (1955), MacDonald (1964), and Kaula (1964) assumed constancy of the geometric lag angle, while Singer (1968) and Mignard (1979, 1980) asserted constancy of the time lag. Thus, each of these two models was based on a certain law of scaling of the geometric lag. The actual dependence of the geometric lag on the frequency is more complicated and is determined by the rheology of the planet. Besides, each particular functional form of this dependence will unambiguously fix the appropriate form of the frequency dependence of the tidal quality factor, Q. Since at present we know the shape of the dependence of Q upon the frequency, we can reverse our line of reasoning and single out the appropriate actual frequency-dependence of the angular lag. This dependence turns out to be different from those employed hitherto, and it entails considerable alterations in the time scales of the tide-generated dynamical evolution. Phobos' fall on Mars is an example we consider.Comment: arXiv admin note: substantial text overlap with arXiv:astro-ph/060552

Theoretical Debates on the Cultural Consequences of Globalization and Its Implication in the Light of the Ethiopian Culture

This paper examined the cultural consequences of globalization in line with different perspectives. The study relied on qualitative research approach along with secondary sources of data so as to analyze the relationship between culture and globalization. Even though people of the world have made closer relations for elongated and continuous periods of time, the pace of interactions, exemplified by the global flows of people, capital, information, commodities, culture etc, has shown significant improvement recently owing to the force of globalization. Thus, globalization, as a multifaceted process, is portrayed by the existence of continuous and multiple linkages on a global scale. One of the interactions by which globalization has been manifested; one is the cultural ties amongst nations. In these processes of cultural connectivity, there exist contact and exchange of elements among the world’s cultural rainbow having an array of end results, namely, homogenization, heterogenization, hybridization and polarization thesis. Keywords: Culture, globalization, homogenization, heteroginazation, hybridization, polarization, cultural imperialism DOI: 10.7176/IAGS/77-02 Publication date: November 30th 201

Successful resolution of a hemorrhagic pancreatic pseudocyst ruptured into the stomach complicating obstructive pancreatitis due to pancreatic cancer: a case report

BACKGROUND: Hematemesis is uncommon as an initial presenting symptom in pancreatic cancer. We present herein a case of a pseudoaneurysm that ruptured and fistulized into the stomach. The pseudoaneurysm was secondary to a pancreatic pseudocyst complicating obstructive pancreatitis due to pancreatic cancer. The patient was successfully treated using trans-arterial embolization followed by curative surgery. CASE PRESENTATION: A 61-year-old man presented to the emergency room with hematemesis. Laboratory examinations revealed a low level of hemoglobin (5.0 g/dl). The patient had presented to another hospital due to hematemesis 1 month before presenting to our hospital. A low-density mass in the pancreatic body with dilatation of the distal main pancreatic duct and a pseudocyst in the pancreatic tail had been observed by radiology at the previous hospital. Further investigation had been planned. Abdominal computed tomography on admission to our hospital demonstrated a pseudoaneurysm in close contact with the wall of the pseudocyst of the pancreatic tail, compressing the stomach. The pseudoaneurysm had not been detected by abdominal computed tomography at the previous hospital. Emergency selective angiography revealed that the pseudoaneurysm arose from the left gastroepiploic artery branching from the splenic artery. Trans-arterial embolization of the left gastroepiploic artery through the splenic artery was successfully performed. Elective distal pancreatectomy and splenectomy with regional lymph node dissection combined with partial resection of the stomach was performed 3 weeks after coil embolization. Pathological examination revealed a moderately differentiated tubular adenocarcinoma in the pancreatic body with regional lymph node metastasis and revealed the pseudoaneurysm rupturing into the pancreatic pseudocyst. The patient has experienced no tumor recurrence or metastasis during 1 year of follow-up. CONCLUSIONS: Spontaneous rupture of a pseudoaneurysm is a rare and potentially lethal complication of a pancreatic pseudocyst. Most affected patients have a history of alcoholism and suffer from acute or chronic pancreatitis. To our knowledge, this is the first reported case of a hemorrhagic pancreatic pseudocyst complicating obstructive pancreatitis due to pancreatic cancer

Adenosquamous carcinoma of the ampulla of Vater: a case report and literature review

BACKGROUND: Adenosquamous carcinoma of the ampulla of Vater is extremely rare, and its clinicopathological features are limited and described in few previous case reports. Here, we report curative resection of adenosquamous carcinoma of the ampulla of Vater at an early stage. CASE PRESENTATION: An 81-year-old woman was referred to our hospital for investigation of the frequent elevation of hepatic and biliary enzymes and dilatation of the intrahepatic bile ducts. Preoperative examinations revealed an exposed reddish tumor in the ampulla of Vater, which was diagnosed on biopsy to be adenocarcinoma with squamous cell carcinoma component. Pylorus-preserving pancreaticoduodenectomy with regional lymph node dissection was performed. Pathological examinations revealed the presence of two malignant components in the lesion, including poorly differentiated tubular adenocarcinoma and squamous cell carcinoma, without invasion beyond the sphincter of Oddi or into the duodenal submucosa. These squamous cell carcinoma and adenocarcinoma components in the tumor comprised approximately 30 and 70 % of the lesion, respectively. No metastasis into regional lymph nodes was observed, and the patient experienced no tumor recurrence or metastasis until 20 months after surgery. CONCLUSION: We identified only six reported cases of adenosquamous carcinoma of the ampulla of Vater in the English literature, and all of these patients died of recurrence within 14 months after surgery. To the best of our knowledge, this is the first report of adenosquamous carcinoma of the ampulla of Vater that was curatively resected at an early stage. Although more number of studies on clinicopathological findings are required to determine the appropriate surgical indication, we suggest that surgery remains the mainstay therapy for adenosquamous carcinoma of the ampulla of Vater detected at an early stage

MYOCARDITIS DIAGNOSTIC CARDIAC MAGNETIC RESONANCE IMAGING: LITERATURE REVIEW

Define-se miocardite como um processo inflamatório do miocárdio, associado à disfunção cardí­aca, podendo ser mediante exposição a agentes infecciosos e quí­micos, processos inflamatórios e autoimunes ou drogas, pode acometer outras estruturas cardí­acas, sendo mais comum o pericárdio. A grande variedade de apresentação clí­nica da miocardite estende-se desde casos assintomáticos a episódios de morte súbita. Quando sintomáticos sabe-se que a insuficiência cardí­aca é a apresentação clí­nica mais frequente. O acometimento por miocardite ocasiona alterações eletrocardiográficas tí­picas, significativas e importantes, podendo eventualmente ser semelhantes a achados do quadro de sí­ndrome coronariana. O método diagnóstico de miocardite por RM, está adquirindo importância singular e imprescindí­vel na investigação e elucidação nos casos considerados clinicamente suspeitos, principalmente quando o diagnóstico anteriormente dependia exclusivamente de biópsia miocárdica. O objetivo desta revisão literária é apresentar a importância do método de diagnóstico por Ressonância Magnética nos estudos de miocardite e patologias associadas.Define-se miocardite como um processo inflamatório do miocárdio, associado à disfunção cardí­aca, podendo ser mediante exposição a agentes infecciosos e quí­micos, processos inflamatórios e autoimunes ou drogas, pode acometer outras estruturas cardí­acas, sendo mais comum o pericárdio.

Seismicity controlled by resistivity structure : the 2016 Kumamoto earthquakes, Kyushu Island, Japan

The M JMA 7.3 Kumamoto earthquake that occurred at 1:25 JST on April 16, 2016, not only triggered aftershocks in the vicinity of the epicenter, but also triggered earthquakes that were 50–100 km away from the epicenter of the main shock. The active seismicity can be divided into three regions: (1) the vicinity of the main faults, (2) the northern region of Aso volcano (50 km northeast of the mainshock epicenter), and (3) the regions around three volcanoes, Yufu, Tsurumi, and Garan (100 km northeast of the mainshock epicenter). Notably, the zones between these regions are distinctively seismically inactive. The electric resistivity structure estimated from one-dimensional analysis of the 247 broadband (0.005–3000 s) magnetotelluric and telluric observation sites clearly shows that the earthquakes occurred in resistive regions adjacent to conductive zones or resistive-conductive transition zones. In contrast, seismicity is quite low in electrically conductive zones, which are interpreted as regions of connected fluids. We suggest that the series of the earthquakes was induced by a local accumulated stress and/or fluid supply from conductive zones. Because the relationship between the earthquakes and the resistivity structure is consistent with previous studies, seismic hazard assessment generally can be improved by taking into account the resistivity structure. Following on from the 2016 Kumamoto earthquake series, we suggest that there are two zones that have a relatively high potential of earthquake generation along the western extension of the MTL
