The emerging field of soundscape ecology views ecosystems in terms of biophony, geophony and anthrophony. Soundscape ecology considers the effects of sound on fauna, and this research focuses on anuran breeding lek soundscapes. The sensitivity of anuran breeding leks to acoustic disturbances makes breeding leks an important venue for a comparative soundscape study. We made long-term（〉 24 h） sound recordings in three representative wetlands and short-term（〈 30 min） recordings in ten sites in the Pannonian Biogeographical Region of Hungary and around the Hungary and Slovakia border. Long-term soundscapes of the floodplain stretch, where there is relatively minor anthrophonical disturbance, showed an obvious circadian change in sound intensities. The site with moderate sound contamination exhibited a disturbed pattern of circadian sound variation, while the site with heavy traffic noise displayed an apparently random temporal soundscape. At different amphibian breeding sites during mating season, our short-term recordings were dominated by anuran calls, bird songs and wind noises, while insect calls and rain were present to a lesser degree. Our study indicates that vehicle traffic noise is a severe imposition to the natural soundscape, and suggests that soundscape monitoring can provide a reliable and sensitive index of environmental change for both short-term and long-term periods.

Distal triceps injuries(including snapping triceps):A systematic review of the literature

AIM To review current literature on types of distal triceps injuryand determine diagnosis and appropriate *** We performed a systematic review in PubM ed, Cochrane and EMBASE using the terms distal triceps tears and snapping triceps on the 10 th January 2017. We excluded all animal, review, foreign language and repeat papers. We reviewed all papers for relevance and of the papers left we were able to establish the types of distal triceps injury, how these injuries are diagnosed and investigated and the types of management of these injuries including surgical. The results are then presented in a review paper *** Three hundred and seventy-nine papers were identified of which 65 were relevant to distal triceps injuries. After exclusion we had 47 appropriate papers. The papers highlighted 2 main distal triceps injuries: Distal triceps tears and snapping triceps. Triceps tear are more common in males than females occurring in the 4th-5th decade of life and often due to a direct trauma but are also strongly associated with weightlifting and American football. The tears are diagnosed by history and clinically with a palpable gap. Diagnosis can be confirmed with the use of ultrasound(US) and magnetic resonance imaging. Treatment depends on type of tear. Partial tears can be treated conservatively with bracing and physio whereas acute tears need repair either open or arthroscopic using suture anchor or bone tunnel techniques with similar success. Chronic tears often need augmenting with tendon allograft or autograft. Snapping triceps are also seen more in men than women but at a mean age of 32 years. They are characterized by a snapping sensation mostly medially and can be associated with ulna nerve subluxation and ulna nerve symptoms. US is the diagnostic modality of choice due to its dynamic nature and to differentiate between snapping triceps tendon or ulna nerve. Treatment is conservative initially with activity avoidance and if that fails surgi

Hidden Secrets of the New England IPA

引用

中外酒业 2019年第19期 71-77页

作者： John Paul Maye Robert smith S.S. Steiner Inc. New York NY 10065

New England India Pale Ale (NEIPA), also known as hazy IPA or juicy IPA, is a relatively new beer style being brewed by craft breweries across the Un让ed States. These beers typically have massive hop aroma and flavor yet are not perceived as being very bitter. They can be incredibly hazy, and many impart fruity and juicy flavors. Twelve NEIPAs were analyzed by high-performance liquid chromatography for various hop compounds, and several tests were conducted on the haze itself to determine what it is and is not. Experiments conducted on these beers exposed the hidden secrets of NEIPA. The results indicated that the vast majority of the haze is polyphenol—protein haze and that the haze can act as a carrier to more of the nonpolar hop compounds than are typically found in West Coast style IPA.

Effect of sedative agent selection on morbidity, mortality and length of stay in patients with increase in intracranial pressure

引用

World Journal of Emergency Medicine 2018年第4期9卷 256-261页

作者： Brian G.Cornelius Elizabeth Webb Angela Cornelius Kenneth W.G.smith Srdan Ristic Jay Jain Urska Cvek Marjan Trutschl Department of Anesthesia University Health-Shreveport Department of Emergency Medicine Louisiana State University Health Sciences Center Laboratory for Advanced Biomedical Informatics Department of Computer Science Louisiana State University Shreveport

BACKGROUND: To identify the effects of sedative agent selection on morbidity, mortality, and length of stay in patients with suspected increase in intracranial pressure. Recent trends and developments have resulted in changes to medications that were previously utilized as pharmacological adjuncts in the sedation and intubation of patients with suspected increases in intracranial pressure. Medications that were previously considered contraindicated are now being used with increasing regularity without demonstrated safety and effectiveness. The primary objective of this study is to evaluate and compare the use of Ketamine as an induction agent for patients with increased intracranial pressure. The secondary objective was to evaluate and compare the use of Etomidate, Midazolam, and Ketamine in patients with increased intracranial pressure. METHODS: We conducted a retrospective chart review of patients transported to our facility with evidence of intracranial hypertension that were intubated before trauma center arrival. Patients were identifi ed during a 22-month period from January 2014 to October 2015. Goals were to evaluate the impact of sedative agent selection on morbidity, mortality, and length of ***: During the review 148 patients were identifi ed as meeting inclusion criteria, 52 were excluded due to incomplete data. Of those the patients primarily received; Etomidate, Ketamine, and Midazolam. Patients in the Ketamine group were found to have a lower mortality rate after injury stratifi cation. CONCLUSION: Patients with intracranial hypertension should not be excluded from receiving Ketamine during intubation out of concern for worsening outcomes.

α-甲基苯乙烯在三相浆化反应器中加氢的动态研究表明,催化剂还原温度对吸附平衡常数、吸附和表面反应速率系数有明显的影响。实验在全混浆化反应器中进行,温度为22℃,38℃和50℃,当还原温度从250℃增加到510℃时,PdCl2还原为 Pd 的 Pd 分散度减小,从而使平衡吸附,吸附和表面反应速率系数均减小。吸附热和表面反应活化能分别为15.9和41.8KJ/mol,且不随还原温度而变。对于三个不同还原温度,其金属分散度的相对大小可从平衡吸附系数计算,发现其结果与 Boitiaux 等的实验结果一致。

目的通过观察小儿不同剂量顺式阿曲库铵的肌松作用，评价是否存在封顶效应，探讨小儿合适的麻醉诱导剂量。方法 45例择期手术的患儿，年龄15～50月，ASAⅠ或Ⅱ级，随机分为3组（n=15）：顺式阿曲库铵0．1mg／kg组（A组）、顺式阿曲库铵0．15mg／kg组（B组）、顺式阿曲库铵0．2mg／kg（C组）。采用TOF-Guard肌松监测仪对尺神经行连续四个成串（TOF）刺激，监测拇内收肌肌颤搐变化；静脉注射异丙酚2mg／kg、芬太尼2μg／kg及相应剂量顺式阿曲库铵麻醉诱导，吸入O2-N2O和静脉持续输注异丙酚维持麻醉；评价气管插管条件评估分级，监测诱导期间血液动力学变化，记录起效时间（肌松药注毕至T1达最大抑制的时间）、临床肌松维持时间（肌松药注毕至T1恢复5％的时间）、临床肌松有效作用时间（T1从最大抑制至恢复25％的时间）、恢复指数（rrl恢复从25％至75％的时间）、体内肌松作用时间（肌松药注毕至T1恢复95％的时间）。结果 3组气管插管条件评估分级比较差异无统计学意义；三组T1达最大抑制时心率、平均动脉压组间和组内比较差异均无统计学意义。与A组相比，B组、C组起效时间较短，临床肌松维持时间、临床肌松有效作用时间、体内肌松作用时间较长（P〈0．01）；三组恢复指数差异无统计学意义。与B组相比，C组起效时间差异无统计学意义，但临床肌松维持时间、临床肌松有效作用时间、体内肌松作用时间较长（P〈0．05或0．01）。结论小儿芬太尼复合异丙酚时，顺式阿曲库铵0．15mg／kg（3倍ed95）是麻醉诱导的适宜剂量。
