A comparative Study on the Utilization of corn Pericarp and Peanut Hull in the Production of Ethanol and the Impact on Food Economics

引用

Food and Nutrition Sciences 2016年第11期7卷 1010-1020页

作者： j. L. Herring V. c. Narayanan Department of Food & Animal Sciences Alabama A&M University Normal AL USA

corn pericarp and peanut hull (lignocellulosic materials) which are food industry by-products were used as substrates in this study. Alkaline hydrogen peroxide (H2O2) pretreatments at 0%, 2.5% and 5% were used for the removal of lignin. Simultaneous Saccharification and Fermentation (SSF) and Separate Hydrolysis and Fermentation (SHF) were conducted using Aspergillus niger (strain 201201) and Saccharomyces cerevisiae (strain 26603). Aspergillus niger was added on day 1 to all samples with inoculation treatments of S. cerevisiae at one-day intervals (A = Day 1, B = Day 2, c = Day 3 and D = Day 4). Pretreatment with 2.5% H2O2 was more beneficial in the removal of lignin for both substrates. corn pericarp yielded an ethanol concentration of 22.2 g/L in c and 21.78 g/L in D of 2.5% H2O2 pretreatment. Peanut hull with 2.5% H2O2 pretreatment in D yielded a higher concentration at 10.38 g/L compared to other inoculation treatments. The highest ethanol yielded on a percentage basis for corn pericarp was 45.04% in c of 2.5% H2O2 pretreatment and 24.6% in D of 2.5% H2O2 pretreatment for peanut hull.

Ultrasound-Guided Dorsal Scapular Nerve Blockade in the Diagnosis and Management of Neck Pain

引用

Pain Studies and Treatment 2023年第2期11卷 9-14页

作者： Alena Boros Paul j. Ryan Dominic c. Harmon School of Medicine Faculty of Education & Health Services University of Limerick Limerick Ireland Department of Anaesthesia and Pain Medicine University Hospital Limerick Limerick Ireland

Neck pain is common and has multiple sources, but correct diagnosis and matched treatment provide the best outcomes. The first description of ultrasound-guided dorsal scapular nerve blockade using a single-shot local anesthetic technique for the diagnosis and treatment of neck pain is reported. A 38-year-old female patient presented with neck pain, and the history and clinical examination strongly suggested myofascial pain affecting the middle scalene muscle. The pain had been unresponsive to pharmacological therapy or physiotherapy. After identifying the dorsal scapular nerve (DSN) in the body of the middle scalene muscle, an ultrasound-guided nerve block was performed using a single injection of local anesthetic to alleviate the patient’s pain. It has been demonstrated that the dorsal scapular nerve can be identified in the neck and effectively blocked using ultrasound guidance. This technique has the potential to assist in the diagnosis and treatment of neck pain originating from the middle scalene muscle.

Biologically inspired shell-hollow particles for designing efficient passive all-sky radiative cooling

引用

Progress in Natural Science:Materials International 2024年第5期34卷 1093-1099页

作者： Shangsheng Zhang Zengzhi Zhang Kai chen Shuman Xu Xunkai Luo yang Liu jian Wang Shijie Han Yulian Li Hongmei Du School of Mechanical and Electrical Engineering China University of Mining and Technology (Beijing) School of chemical and Environmental Engineering China University of Mining and Technology (Beijing)

Passive radiation cooling（PRc）, as the most promising technology to meet future cooling needs, has attracted great interest. However, there are still huge challenges in manufacturing high-efficiency and low-cost radiant coolers suitable for all-day use. Here, we report a secondary micro-nano shell-hollow structure based on blending method, inspired by the African white beetle Goliathus goliatus. Due to the difference in reflectance between the shell and the internal air, compared with the homogeneous particles, the scattered light has a changed optical path at the interface of the core（air） and the shell（SiO2）, and most of the light escapes from the particles, showing strong total internal reflection. The design ingeniously deposits the nano-sized shell-hollow structure on the surface of the micron-sized shell-hollow structure, achieving high solar reflectance（95 %）and excellent long-wave infrared emissivity（94 %）. Sub-ambient cooling of 7.8 and 4.7°c can be achieved at night and daytime,respectively. Silica microspheres with shell and hollow structure can be prepared by soft template method, which is mature, reliable, simple and *** work provides new ideas for the design and manufacture of highperformance Passive all-day radiative cooling（PARc）.
