he sound development of human societyThe widespread use of pesticides, veterinary drugs, and other agricultural chemicals have contributed to widespread contamination in agricultural productsThe long-term consumption of food with high residues of pesticides and veterinary drugs will cause both acute

and chronic toxicity in humans and induce resistant strains, thus resulting in allergies, cancer, mutation, and teratogenicityIn order to ensure human health and food safety,countries all over the world have issued strict food safety and hygiene standardsThe People’s Republic of China (PRC) has imp

lemented strict monitoring of pesticide and veterinary drug residues, such as maximum residue limits for veterinary drugs in food of animal origin (Announcement No235 of the Ministry of Agriculture of the People’s Republic of China) and national food safety standards: Maximum residue limits for pest

icides in food (GB 2763- 2016)   The commonly used pesticides and veterinary drugs approved in China and the main agricultural products of urban residents’ daily consumption are almost all covered The book is a systematic summary of the high-throughput chromatographymass spectrometry technique for

the analysis of multipesticides, veterinary drugs, and other agricultural chemical residues in agriculture products of plant and animal originIts technical characteristics are mainly embodied in the simultaneous determination of hundreds of compounds, as well as low cost and high efficiency This bo

ok is divided into two volumesIn Volume 1, pesticides and related chemicals are selected as the main research object, while gas chromatographymass spectrometry (GC-MS), gas chromatography-tandem mass spectrometry (GC-MS-MS), and liquid chromatography-tandem mass spectrometry (LC-MSMS) are concernedT

uded in this volume: ①chromatography-mass spectrometry characteristic parameters include retention time, quantitative and qualitative ions, fragment voltage and collision energy, etc.;②performance parameters of the methods include linear equation, linear range and correlation coefficient, etc.; and③

gel permeation chromatography (GPC) purification analysis parameters In Volume 2, the methods for the analysis of 20 species (nearly 200 kinds) of veterinary drug residues in edible animal tissues (muscle, liver, kidney, and fat), dairies (milk and milk powder), bee products (honey, royal jelly, an

d its lyophilized powder), aquatic products (globefish, eel, and roasted eel) and animal urine are selected as main subjects of studyThe 65 analytical methods for the analysis of multiveterinary drug residues are described in different chapters by category (sulfonamides, β-adrenergic agonists, amino

glycosides, chloramphenicols,β-lactams, macrolides, nitrofurans, anabolic steroids, nonsteroidal anabolic steroids, glucocorticoids, fluoroquinolones, tetracyclines, sedatives, pyrazolones, quinoxalines, nitromidazoles, benzimidazoles, levamisole, thiourea pyrimidines, and polyethers), and 90% of th

e methods are LC-MS-MSMeanwhile the physical and chemical properties, efficacy, side effects, and maximum allowable residual limit of all the compounds are also provided In short, this book is the summary of the work of the author team who, for more than 20 years, engaged in the research and practi

ce of detection technology of pesticides and veterinary drug residuesThese methods for the analysis of pesticides and veterinary drugs are innovative research results based on the international frontier of pesticides and veterinary drug residue analysis, and the analytical techniques adopted are new

technologies widely concerned in the field of residue analysis in the world todayThe performance indexes of the methods can meet the requirements of the Codex Alimentarius Commission and the world’s major developed countries; meanwhile the methods are in conformity with the developing trend of inte

rnational residue analysis and they are advanced in the worldIn addition, the methods established in this book have become the current effective national standard methods in China and they can be used as the detection basis of relevant testing institutions and the law basis of the relevant governmen

基於曲電與介電效應之三穩態切換負型膽固醇液晶元件的光電響應

為了解決LC500的問題，作者陳冠然 這樣論述：

本研究於負型液晶DV10001中添加右旋手性分子R5011形成負型膽固醇液晶，接著經由摻雜不同配比濃度之彎曲型液晶分子CB7CB使配製完成之液晶材料具有不同程度的曲電特性，筆者藉此探討負型膽固醇液晶在摻雜彎曲型液晶分子後於不同電場條件下的紋理形成種類以及其光電響應。實驗結果分析中，對於形成紋理之介電頻譜進行首要之探討，透過均勻橫向螺紋態（ULH）紋理於介電實部之曲電鬆弛訊號判斷此材料之曲電特性，接著將其鬆弛強度90%與10%所對應於介電頻譜上之頻率點進行紋理切換頻率區間的劃分，並作為此研究之三穩態紋理切換中操作頻率區間的依據。當操作頻率f < fL，液晶分子因強烈的電流體效應及曲電強度而得以

形成ULH態；在頻率fL < f < fH區間中，曲電特性隨著頻率的增加逐漸變小，漸漸的由介電效應主導，此時液晶分子於電場驅動下形成焦錐態（FC）；當頻率f > fH，此時曲電效應幾乎完全消失，液晶分子受介電效應主導而形成平面態（P）。筆者藉由本研究提供了讀者一套於負型膽固醇液晶達成三穩態紋理切換的分析方法，並透過介電頻譜與光電特性量測詳細地說明其紋理背後的形成機制與應用。

建築產業碳足跡：建築、景觀、室內裝修的碳管理策略(三版)

為了解決LC500的問題，作者林憲德 這樣論述：

　　如今，全球一片碳揭露、碳盤查、碳經濟之聲，全球500大企業已組成「供應鏈領導聯盟」要求旗下供應商公布碳足跡資料，許多廠商擔心產品無碳標籤賣不出去。 　　這隻「碳足跡怪獸」已逃出「潘朵拉的盒子」，建築產業陷入一片「碳恐慌」中，假如我們不勇敢抵禦這「碳足跡怪獸」，也會被這怪獸吞食而亡。本書建築、景觀、室內裝修三產業的碳足跡評估法，是預防「碳足跡怪獸」來襲的防波堤，盼能將衝擊誘導至優質永續產業之方向，希望能以「最誠實的碳足跡認證」之「法器」將這些鬼魅怪獸降服為「坐騎」，讓此「坐騎」做出真正拯救地址的事務。  

L-半胱胺酸在體內和體外實驗對順鉑引起男性生殖之損傷影響

為了解決LC500的問題，作者陳儀滋 這樣論述：

臨床常見治療癌症之化療藥物Cisplatin (CIS)造成睪丸功能障礙之副作用會影響男性生殖功能。睪丸內細胞因氧化壓力增加會促使發炎反應，細胞走向凋亡損傷，亦會發生精子生成異常，最終造成睪丸功能性受損。而L-半胱胺酸 (L-cysteine, CYS)因具有強大抗氧化、抗發炎等功效，但至今對男性生殖影響之相關機制研究尚未明確證實，故本研究目的為考慮臨床輔助治療之應用，以體內及體外模式探討CYS對CIS造成男性生殖損傷之相關改善效應。體外實驗利用TM3及TM4小鼠睪丸細胞株，以MTS試驗及結晶紫染色測定細胞存活率，以Western blot測定血睪障壁、發炎及細胞凋亡相關蛋白表現。結果顯示，

CYS可顯著恢復CIS誘導TM3及TM4細胞存活率，並減少Caspase3、PARP、Bax凋亡相關蛋白表現，同時降低TM3細胞NLRP3及COX2發炎相關蛋白表現，且增加TM4細胞ZO-1結構蛋白表現。亦以CIS建立誘導睪丸損傷之動物模式，實驗期21天後，發現CYS可顯著降低睪丸組織及精子結構損傷，維持血清睪固酮濃度，恢復精子存活狀態，並且減少睪丸PARP蛋白表現。因此，本研究表明L-cysteine可改善Cisplatin對男性生殖之不利影響，顯示L-cysteine具有輔助臨床Cisplatin藥物治療下對男性生殖功能損傷之保護潛力。
