Two phenoxyherbicide nanocomposites, namely cloprop-layered double hydroxide and cloprop-zinc- layered hydroxide nanocomposites, have been synthesized by using co-precipitation and direct reaction method. PXRD pattern showed an expansion of interlayer spacing with the value of 21.0 Åand 22.7 Åfor cloprop-layered double hydroxide and cloprop-zinc-layered hydroxide nanocomposite, respectively. It is evident from FTIR and elemental analyses that both nanocomposites were successfully intercalated between the interlayers of layered metal hydroxide. Controlled release of cloprop anion from interlayer of nanocomposites for both cloprop-layered double hydroxide and cloprop-zinc-layered hydroxide nanocomposite into phosphate solution was rapid initially and slow thereafter. The percentage of accumulated release of cloprop anion from cloprop-zinc-layered hydroxide nanocomposite was slightly higher than that from cloprop-layered double hydroxide nanocomposite. Kinetic behavior of cloprop release was governed by pseudo-second-order for cloprop-layered double hydroxide nanocomposite while parabolic diffusion for cloprop-zinc-layered hydroxide nanocomposite. Results from this study highlight the potential of both nanocomposites as capsulated material for controlled release of cloprop phenoxyherbicides anion.

Introduction: Common bile duct stone (CBDS) is a common clinical problem that can cause serious complications, such as acute cholangitis and pancreatitis. It is important to have an accurate, safe, and reliable method for the definitive diagnosis of CBDS before proceeding to therapeutic endoscopic retrograde cholangiopancrea-tography (ERCP). Objective: To compare the accuracy of trans-abdominal ultra-sound (TAUS) as a diagnostic tool at our institution—Kurdistan Centre for Gastroen-terology & Hepatology (KCGH)—with invasive tool like ERCP in the diagnosis of bile duct stones, using specificity, sensitivity, and positive and negative predictive values. Patient and Method: After obtaining ethical committee approval & informed consent from every patient. This was a prospective study conducted on 71 patients (24 male patients and 47 females patients) where suspected to have CBDS depending on history, clinical suspicion and blood tests. Their ages range between (2 - 88 years). Both TAUS and ERCP were performed. Final diagnosis was confirmed de-pending on ERCP as it served as a diagnostic standard in diagnosing CBDS. Result: In 71 patients suspected to have CBDS by TAUS, only 46 patients had stone (65%), and 55 patients had stone by ERCP (77%). In our result, sensitivity, specificity, pos-itive predictive value and negative predictive value for TAUS were 80%, 87.5%, 65.5% and 56%, respectively. Conclusion: TAUS can play an important role as an initial screening procedure for CBDS detection because of the various advantages like easy availability, cost effectiveness, no requirement of contrast material and lack of ionizing radiation but should done with other imaging modality to avoid se-rious complication of ERCP.

以牛卵巢卵母细胞体外受精获取囊胚期胚胎，比较体外受精牛胚胎不同获取内细胞团的方法和不同培养液对体外培养胚胎干细胞能力的影响。结果表明，囊胚期胚胎不除去透明带而直接培养产生胚胎干细胞，初次克隆率为55％；胰酶法去透明带分离的内细胞团（ICM）培养产生胚胎干细胞，初次克隆率为90％。免疫外科法去透明带分离的ICM在4种不同的培养液中，初次克隆率分别为16．4％、11．5％、21．8％、18．2％，但是其分离的ICM经传代后形成的衍生细胞不易发生分化，经过4～6代的传代，仍然保持其完整的形态，说明免疫外科法是一种理想的牛ICM分离法，培养液为D20＋LIF（40ng／mL）可用于牛胚胎干细胞培养。

Open Journal of Energy Efficiency 2022年第3期11卷 122-141页

This project strived to develop a prototype road piezoelectric energy harvester RPEH system using five Lead Zirconate Titanate (PZT) PZT 5H modules (stacks) that are embedded in the road by means of a housing unit to harvest energy from vehicles stressing the modules. The work is an extension of our previous published work in the same journal. The design considered many factors to optimize the harvested energy. The proposed system first captures mechanical energy using a designed module that transfers the energy to the piezoelectric stacks. Then the captured energy will be converted into electrical energy by the piezoelectric phenomenon. The harvested energy is stored in a storage device, then analyzed by an oscilloscope through the acquisition of the harvested voltage, current, power, and energy. When testing the RPEH with the wheel tracking machine, varying resistor loads where connected to the output of the RPEH to address the optimum power delivered to the load. The optimum load was found to be 950 kΩ, and the optimal harvested energy was recorded as 45 uJ.
