Dublin's Gresham Hotel, where Gabriel and Gretta Conroy end their evening in Joyce's most famous short story, has a fascinating history. It was founded in 1817 by Thomas Gresham, who began life as a foundling rescued from the steps of London's Royal Exchange and was thereby given the name of the Renaissance statesman who built that exchange. This sixteenth-century Thomas Gresham was even better known, however, for his eponymous ‘Gresham's Law’. Both Gresham's Law and the hotel setting and history enter into and help to shape ‘The Dead’. Questions of value and valuing suggested by Gresham's Law are shown to be more complicated than they initially appear, as they intersect with the various forms of hospitality traced in the story. The ‘secondary’ quality of the famous Dublin hotel (built by the second, unknown Thomas Gresham) underscores – and ultimately redeems – the theme of secondariness that runs through ‘The Dead’.

The present investigation was carried out to study the refrigeration preservation of the cauda epididymal retrieved spermatozoa of buck in Tris egg yolk citrate (TEYC) dilutor containing pomegranate juice as antioxidant additive. The retrieved cauda epididymal spermatozoa extended in TEYC dilutor were studied in five groups by adding different concentration of pomegranate juice as additive (0% as control T1 group and 5%, 10%, 15% and 20% as treatment T2, T3, T4 and T5 groups, respectively) and storing at refrigerated temperature up to 48 hr. The results showed that the control extender had the least dead, abnormal and HOS non-reacted sperm percent among all treatments tested and that with increasing the pomegranate juice concentration in dilutor, the percentage of the dead, abnormal and HOST non-reacted spermatozoa increased significantly. The same trend was observed at all 12 hourly storage intervals indicating its detrimental effect on epididymal sperms of bucks at refrigeration temperature. The dead, abnormal, and HOST non-reacted sperm were significantly and positively interrelated with each other (r = 0.53-0.83). It was concluded that the inclusion of pomegranate juice in TEYC dilutor did not show any beneficial/antioxidant effect on epididymal sperms of buck in fresh or refrigerated semen and in fact all the levels of pomegranate juice (5% to 20%) were detrimental to cauda epididymal spermatozoa of a buck.

Trailing oil is the tail section of contamination in oil pipelines. It is generated in batch transportation, for which one fluid, such as diesel oil follows another fluid, such as gasoline, and it has an effect on the quality of oil. This paper describes our analysis of the formation mechanism of trailing oil in pipelines and our study of the influence of dead-legs on the formation of trailing oil. We found that the oil replacement rate in a dead-leg is exponentially related to the flow speed, and the length of the dead-leg is exponentially related to the replacement time of the oil. To reduce the amount of mixed oil, the main flow speed should be kept at about 1.6 m/s, and the length of the dead-leg should be less than five times the diameter of the main pipe. In our work, the Reynolds time-averaged method is used to simulate turbulence. To obtain contamination-related experimental data, computational fluid dynamics (CFD) software is used to simulate different flow rates and bypass lengths. MATLAB software was used to perform multi-nonlinear regression for the oil substitution time, the length of the bypass, and the flow speed. We determined an equation for calculating the length of the trailing oil contamination produced by the dead-leg. A modified equation for calculating the length of the contamination was obtained by combining the existing equation for calculating the length of the contamination with new factors based on our work. The amounts of contamination predicted by the new equation is closer to the actual contamination amounts than predicted values from other methods suggested by previous scholars.

Quality of the indoor environment is determined by physical and psychophysical factors. People spend in the interiors most of the time during the day. Therefore indoor visual, thermal and acoustic effects are important for their health and work productivity. Visual environment can be evaluated in term of daylight availability, spatial luminance distribution and access to sunlight. Unless availability of sky/diffuse light can be considered for window design because of low intensities, the direct sun radiation with its original wavelength composition and high intensity is important for health and stimulation of human body organs in moderate climatic zones. To evaluate access to sunlight, there is necessary to determine the sun position on the sky, dimensions of envelops and windows as well as orientation of significant apertures and potential impact of external obstructions. Sun rays reaching the window surface can or cannot penetrate into the interior. This depends on the angle of sun beam incidence, orientation and dimensions of the aperture, thickness and structure of the envelope. Angle in which incident rays penetrate in the interior is so called acceptance angle. Angle in which incident rays are not causing insolation of interiors or cannot penetrate through the window glazing is so called dead angle. This paper analyses and discusses the meaning and dimensions of the dead angle.

In assessing the characteristics of Cicero's oratory we are in the unfortunate position of being unable to compare him with his contemporaries and predecessors. The speeches of Hortensius and of the other famous orators of Cicero's day are lost, as are those of Crassus and Antonius, the much admired figures of his boyhood, with whom, according to the Brutus, Roman oratory first equalled Greek. Yet though we know little of the other orators of the Roman Republic, it is possible by a study of Cicero's speeches and of his oratorical writings to get a fairly good idea of his special characteristics.A passage in the Brutus will serve as a useful introduction to a brief study of Ciceronian oratory.[‘Before the time of Hortensius] there was no orator’, says Cicero, ‘who appeared to have studied literature more deeply than the common run of men—literature which is the fountain-head of perfect eloquence; no one who had embraced philosophy—the mother of all good deeds and good words; no one who had learnt civil law—a thing most necessary for private cases, and essential to the orator's good judgement; no one who had at his command the traditions of Rome, from which if occasion demanded he could call up most trustworthy witnesses from the dead; no one who by rapid and neat mockery of his opponent could unbend the minds of the jurymen and turn them for a while from solemnity to smiling and laughter; no one who could widen an issue and bring his speech from a limited dispute referring to a particular person or time to a general question of universal application; no one who could delight by a temporary digression from the issue, or could move the judge to anger or to tears, or in fact—which is the special quality of the orator—could turn his feelings whithersoever the occasion demanded.’

This study is based on the analysis of water samples collected on a seasonal basis from the wells and springs of the southern basins of the Mountain Aquifer. The Herodion-Beit Fajjar well field is located near the main recharge area between Bethlehem and Hebron. The springs discharge from perched aquifers, or discharge directly into the Dead Sea. The analyses of the samples collected indicate three major water types: calcium carbonate water, calcium-sodium bicarbonate water, sodium chloride water; attributed to the geochemical dissolution and ion exchange processes and to mixing with wastewater. A large number of the samples are contaminated with fecal coliform and therefore unsuitable for drinking without proper disinfection. Most samples range between hard and very hard water indicating high concentrations of calcium and bicarbonte. Some of the samples exceed the nitrates limits of the WHO (1995) and a few exceed the potassium limits, indicating pollution and mixing with wastewater. Chemical treatment is required in order to bring such water up to acceptable drinking water standards. The samples registered a low sodicity and a high salinity hazard. This type of water should be limited and controlled in order to mitigate the possible negative effects on both the soil and the cultivation of plants.

Abstract: Disasters in our country have become very important issues. It is said that our country is a disaster supermarket due to the quantity and quality of disasters in Indonesia from 2000-2010. Disasters claimed both material and human lives. Disasters such as earthquakes and tsunamis often resulted in the findings of unidentified bodies (the disaster victims). Identification of a dead body is very important in a disaster. The method used to identify the dead body must be standarized - according to forensic identification methods and standard DVI procedures (Disaster Victim Identification) in reference to Interpol. Additionally, the methods can also assist the police in the personal identification of cases whose identities are still questionable. Victim identifications in turn will help to determine the perpetrators. Keywords: disaster, identification, identification methods, DVI     Abstrak: Isu bencana di negara kita Indonesia ini sudah sangat sering didengar karena cuku banyak bencana yang telah terjadi di negara kita. Negara kita bahkan disebut ‘supermarket bencana’ akibat banyaknya bencana yang terjadi di Indonesia dalam kurun waktu 2000-2010. Bencana tidak hanya memakan korban material saja tetapi juga korban jiwa. Pada bencana- bencana seperti gempa bumi dan tsunami sering didapati jenazah-jenazah yang identitasnya tidak diketahui. Penentuan identitas jenazah disini sangat penting; untuk itu dapat digunakan metode-metode identifikasi menurut forensik dan juga prosedur-prosedur standard DVI (Disaster Victim Identification) yang mengacu pada Interpol. Selain itu, metode-metode tersebut bisa membantu pihak kepolisian dalam penyidikan kasus-kasus dimana identitas korban masih diragukan; dan juga untuk menentukan pelaku kejahatan pada kasus-kasus  pembunuhan, pemerkosaan, dan lainnya yang berhubungan dengan masalah identifikasi. Kata kunci: bencana, identifikasi, metode identifikasi, DVI
