An indirect sensitive and selective spectrophotometric method has been developed for the determination of cephalexin monohydrate (CEM) ceftriaxone sodium (CFX) and cefotaxim sodium (CEF) in bulk and pharmaceutical formulation. The method is based on the oxidation of (CEM), (CFX) and (CEF) in hydrochloric acid medium with known excess on N-Bromosuccinimde and subsequent determination of unreacted oxidant by decolorization of Evans blue dye (EB) and measure the absorbance of residual dye at 608 nm. Calibration curves of evans blue dye in the presence of drugs were rectilinear over the ranges 1.0-9.0 , 1.0-8.0 and 1.09.0 μg/ml with molar absorptivity 2.75×10 , 9.28×10 and 7.81×10 l.mol.cm and average recoveries 98.97, 102.08 and 100.08% for CEM, CFX and CEF respectively with RSD of less than 3.29%. The method was free from interference of many excipients and additives commonly found in pharmaceutical formulations. The developed method was successfully applied for determination of the studied drugs in their pharmaceutical formulation resulted in a good agreement with certified value and standard addition procedure.
建立了间接灵敏选择性分光光度法测定原料药和制剂中头孢氨苄一水(CEM)、头孢曲松钠(CFX)和头孢噻辛钠(CEF)的含量。该方法是基于(CEM), (CFX)和(CEF)在已知n -溴琥珀酰亚胺过量的盐酸介质中氧化,然后通过对埃文斯蓝染料(EB)的脱色来测定未反应的氧化剂,并在608 nm处测量残留染料的吸光度。在药物存在下,埃文斯蓝染料在1.0 ~ 9.0、1.0 ~ 8.0、1.09.0 μg/ml范围内呈直线关系,摩尔吸光度分别为2.75×10、9.28×10和7.81×10 l.mol.cm, CEM、CFX和CEF的平均回收率分别为98.97、102.08和100.08%,RSD < 3.29%。该方法不受制剂中常见的辅料和添加剂的干扰。所建立的方法成功地应用于所研究药物制剂的测定,结果与认证值和标准添加程序吻合良好。

The drift-diffusion model is considered as one of the most important models which is used to describe the characteristics of semiconductor devices and can be applied to wide range of applications started from micro up to nano scale devices after applying the suitable correction on it. The Poisson, continuity, and current equations are considered as the basic equations for semiconductor devices, these equations are partial differential equations, used in the drift diffusion model. These equations described the semiclassical electron and hole transport in semiconductor in the presence of uniformly applied electric field. In this paper a numerical method (finite difference method) has been used to find the solution of these equations depending on Gummel method and Scharfetter-Gummel scheme, the drift diffusion model is applied after many approximation and suitable boundary condition which has been considered for the pn diode in both equilibrium and non-equilibrium cases at room temperature, from this simulation model a MATLAB program has been prepared to obtained diode parameters as a function of distance at the junction region, these parameters are (conduction band, carrier concentration, electric field and charge density) two diode model has been tested with different doping concentration the first with NA = ND and the second with NA > ND also the diode characteristic in the forward biased is obtained. Keyword: simulation of pn diode, drift diffusion model, Gummel method. فا رجنلاا جذومنل يددعلا لحلا ءاصقتسا يئانث يف راشتنلاا pn ذ ي نوكيلسلا يف دحاو دعب را رقتسلاا ةلاح تباث يرون انا زور 1 و نيسح حلاص دمحم زاتمم * 2 1 , 2 ءايزيفلا مسق , ةفرصلا مولعلل ةيبرتلا ةيلك , لصوملا ةعماج قا رعلا ,لصوملا , صخلملا دعي فا رجنا جذومن راشتنا كميو تلاصوملا هابشا طئابن صئاصخ فصول ةمدختسملا جذامنلا مها نم ن نم عساو ىدم ىلع هقيبطت تاقيبطتلا داعبلاا ىلا )ةيوركياملا( ةقيقدلا داعبلاا نم دتمت .اهل ةبسانملا تاحيحصتلا لاخدا دعب ةيونانلا نوساوب ةلداعم ربتعت ، جذومن يف مدختست ةيئزج ةيلضافت تلاداعم يهو تلاصوملا هابشا يف ةيساسلاا تلاداعملا نم رايتلا ةلداعمو ةيرا رمتسلاا ةلداعمو فا رجنلاا هذه فصت .راشتنلاا يجراخ يئابرهك لاجم دوجو لاح يف تاوجفلاو تانورتكللإل يكيسلاكلا ةبش لاقتنلاا تلاداعملا نم .مظت لموك ةقيرط ىلع دامتعلااب تلاداعملا هذهل لولح داجيلإ )ةدودحملا قورفلا ةقيرط( ةيددع ةقيرط قيبطت ثحبلا اذه يف مت Journal of Education and Science (ISSN 1812-125X), Vol: 30, No: 1, 2021 (46-57) Downloaded from https://edusj.mosuljournals.com/ 47 رتفريش ططخمو .لموك فا رجنلاا جذومن قيبطت مت – اشتنلاا ر ، ةبسانم ةيدودح طورش مادختسابو لحلل تابيرقت ةدع ءا رجا دعب يئانث ىلع pn وتلا ةلاح يف اوتلا مدعو نزا .ةفرغلا ةرا رح ةجرد دنع نز ح جمانرب دادعإب ةاكاحم ءا رجا مت ا س و ةغلب يب MATLAB نوكيلسلا يئانثل تاملعم ىلع لوصحلاو pn نم لك ىلع لوصحلا مت ذا .ةفاسملل ةلادك ليصوتلا ةمزح ، تلاماحلا زيكرت ، لاجملا لا ةلاح يف ةفاسملل ةلادك ةنحشلا ةفاثكو يئابرهكلا امدنع يا نزاوت NA = ND امدنع يا نزاوتلا مدع ةلاح يفو NA > ND .نيتلاحلا نيب ةنراقملا تمتو :ةلادلا تاملكلا يئانث ةاكاحم pn نا جذومن ، فارج نا .لموك ةقيرط
漂移-扩散模型被认为是描述半导体器件特性的最重要的模型之一,在对其进行适当的修正后,可以适用于从微到纳米级器件的广泛应用。泊松方程、连续性方程和电流方程被认为是半导体器件的基本方程,这些方程是偏微分方程,用于漂移扩散模型。这些方程描述了均匀电场作用下半导体中电子和空穴的半经典输运。本文采用数值方法(有限差分法)根据Gummel法和Scharfetter-Gummel格式求解了这些方程,并对pn二极管在室温下的平衡态和非平衡态进行了多次近似和适当的边界条件后,采用了漂移扩散模型。根据该仿真模型编制了MATLAB程序,得到了二极管参数与结区距离的函数关系,这些参数分别为:导带、载流子浓度、电场和电荷密度。分别对NA = ND和NA > ND两种不同掺杂浓度下的二极管模型进行了测试,得到了二极管在正向偏置中的特性。关键词:pn二极管仿真,漂移扩散模型,Gummel法。فارجنلااجذومنليددعلالحلاءاصقتسايئانثيفراشتنلااpnذينوكيلسلايفدحاودعبرارقتسلااةلاحتباثيرونانازور1ونيسححلاصدمحمزاتمم* 2 1 2ءايزيفلامسق,ةفرصلامولعللةيبرتلاةيلك,لصوملاةعماجقارعلا,لصوملا,صخلملادعيفارجناجذومنراشتناكميوتلاصوملاهابشاطئابنصئاصخفصولةمدختسملاجذامنلامهانمننمعساوىدمىلعهقيبطتتاقيبطتلاداعبلااىلا)ةيوركياملا(ةقيقدلاداعبلاانمدتمات。هلةبسانملاتاحيحصتلالاخدادعبةيونانلانوساوبةلداعمربتعت،جذومنيفمدختستةيئزجةيلضافتتلاداعميهوتلاصوملاهابشايفةيساسلااتلاداعملانمرايتلاةلداعموةيرارمتسلااةلداعموفارجنلااهذهفصت。راشتنلاايجراخيئابرهكلاجمدوجولاحيفتاوجفلاوتانورتكللإليكيسلاكلاةبشلاقتنلااتلاداعملانم。مظتلموكةقيرطىلعدامتعلاابتلاداعملاهذهللولحداجيلإ)ةدودحملاقورفلاةقيرط(ةيددعةقيرطقيبطتثحبلااذهيفمت教育和科学杂志》(ISSN 1812 - 125 x),卷:30日不:1,2021(46-57)从https://edusj.mosuljournals.com/下载47رتفريشططخمو。لموكفارجنلااجذومنقيبطتمت——اشتنلاار،ةبسانمةيدودحطورشمادختسابولحللتابيرقتةدعءارجادعبيئانثىلعpnوتلاةلاحيفاوتلامدعونزا。ةفرغلاةرارحةجرددنعنزحجمانربدادعإبةاكاحمءارجامتاسوةغلبيبMATLABنوكيلسلايئانثلتاملعمىلعلوصحلاوpnنملكىلعلوصحلامتذا。ةفاسمللةلادكليصوتلاةمزح،تلاماحلازيكرت،لاجملالاةلاحيفةفاسمللةلادكةنحشلاةفاثكويئابرهكلاامدنعيانزاوتNA = NDامدنعيانزاوتلامدعةلاحيفوNA > ND。نيتلاحلانيبةنراقملاتمتو:ةلادلاتاملكلايئانثةاكاحمpnناجذومن،فارجنا。لموكةقيرط،راشتةمدقملاةيساساةزيكرتلاصوملاهابشادعتلاةروثوةيجولنكتلاتاروطتلايف،تامولعمطئابنيفرمتسملاوريبكلاروطتللةجيتنو。تلااجملاعيمجيفتلاصوملاهابشا。ةيرظنلاتاساردلاترهظةيبيرجتلاتاساردلاةازاومبذاةجذمنلاوةيددعلاقرطلاوةاكاحملاتبعلاساردلايفةفلكلاودهجلاليلقتلكلذوتلاصوملاهابشاطئابنءاداريوطتيفمهملارودلاةيلمعلات[1 - 3]دمتعتو。يفةاكاحملاتلاصوملاهابشاتاساردساسلأابىلعةيكرحةعيبطوتلاصوملاهابشاءايزيفيفةيرظنلاسسلااةنحشلاتلاماحهابشايففريبكلاروطتلاعمودوقعةثلاثذنلم。صوملاهبشيفبئاوشلاةفاثكوعونولصوملاهبشلةمزحلالكشىلاةفاضاتلاصوملايهابشاطئابنلةيددعلاةاكاحملاتحبصاةيددعلاقئارطلاوتابساحلاتلااجمءاملعلاونيثحابللةيوقةيلمعةاداتلاصوملا[4]ذا。اممونانلادودحىلاطئابنلامجحصيلقتةيحاننمتاروطتتزربأةديدعتلايدعتتلخداثيحمكلاكيناكيملاجميفةاكاحملالخدلاتايرظنلاىلعةدئاسلاخدإبلاوةيكيسلاكلاهبشنامزتلوبةلداعمىلعةصاخيمكلاحيحصتلاجذومنلثمىرخلااجذامنكيمنيدورديهلاجذومنوفارجناراشتنامتذااهيلعةيمكلاتاحيحصتلالاخدا(5、6)。فصتيتلاةمهملاتلاداعملانمةيرارمتسلااتلاداعميهتلاصوملاهابشاطئابنتانورتكللإلةلداعموتاوجفلاونوساوب泊松方程وديلوتلاوداحتلااتلاداعميوحتيتلارايتلاتلاداعمتانورتكللإلتاوجفلاو[7]。تلاداعملاهذهويهةيلضافتتلاداعمةيطخريغةيئزجةلوهجميكيتاتسورهكلادهجلاوتاوجفلاوتانورتكللااةفاثكاهيفنوكت[3]،دعلاقئارطلاتروطتهذهلحلةيداعملاةقيرطيهقئارطلاهذهزربانموةيددعلابيلاسلااوقئارطلابريبكلاروطتلاوبوساحلاتاغليفمدقتللةجيتنةثلاثلاتلادGummelططخموScharfetter-Gummel(8 - 10)。 gitten向一个组织的负责人报告了一份报告,其中包括一名检察官拉杰纳·拉斯顿,他是纳兹劳·纳姆拉的兄弟,雷吉·纳兹博拉·纳兹博拉·纳兹博拉·纳兹博拉·纳兹博拉·拉特·拉特拉。在这方面,他还说:“我们必须采取一切

This research was included partially purification of lipoxygenase (LOX) from serum of patients with epilepsy using ammonium sulfate precipitation, dialysis and ion-exchange chromatography with specific activity (0.751 U / mg), (0.935 U/mg) and (2.60 U/mg) respectively. Optimum conditions for enzyme activity were determined. The best enzyme activity was showed at 7 minutes of incubation time, 3 minutes of reaction time, pH = 7, temperature 40Co and finally substrate concentration (linoleic acid) was (1.2 mmol/L). By applying Michaelis-Menten and Lineweaver-Burk Equations, Michaelis-Menten constant (km) and Vmax values were found 0.3 (mM) and (0.9 U/ml) respectively. Also this study included the effect of some antiepileptic drugs such as valproic acid, carbamazepine and acetozolamide. Acetazolamide showed the highest inhibition of lipooxygenase activity ( 96.2 )٪ , valproic acid(95.6) and Carbamazapine ( 95.1 )٪ . Inhibition type was studied and the result showed noncompetitive inhibition by using Lineweaver-Burke plot for all above drugs.

Optimum conditions for enzyme activity were determined. The best enzyme activity was showed at 7 minutes of incubation time, 3 minutes of reaction time, pH = 7, temperature 40Co and finally substrate concentration (linoleic acid) was (1.2 mmol/L). By applying Michaelis-Menten and Lineweaver-Burk Equations, Michaelis-Menten constant (km) and Vmax values were found 0.3 (mM) and (0.9 U/ml) respectively. Also this study included the effect of some antiepileptic drugs such as valproic acid, carbamazepine and acetozolamide. Acetazolamide showed the highest inhibition of lipooxygenase activity ( 96.2 )٪ , valproic acid(95.6) and Carbamazapine ( 95.1 )٪ .

A simple, accurate and sensitive indirect spectrophotometric method has been developed for the determination of salbutamol sulphate and mefenamic acid in pure forms and in pharmaceutical preparations (capsule, syrup, tablet). This method based on the bromination of the drug with Nbromosuccinimide in acidic medium and the unreacted oxidizing agent react with constant amount of Azur-A dye solution due to bleach their colour and measured the absorbance of the residual colour dye at 606.5 nm.The molar absorptivity for salbutamol sulphate and mefenamic acid are 2.3 × 10 L.mol .cm and 8.1× 10 L.mol.cm respectively. Beer's Law was obeyed over the concentration range of 1.6 -12.8 μg/ml for salbutamol sulphate and1.6 -13.6 μg/ml for mefenamic acid. The limit of detection (LOD) were 0.0367μg/ml and limit of quantitation (LOQ) were 0.1226 μg/ml for both drugs. In addition, the recovery levels of the drugs were in the range 100.56% and 100.74%. The method was created to be simple, cost-effective and rapid because it does not involve any solvent extraction. The developed method was successfully applied for the determination of the studied drugs.
建立了一种简单、准确、灵敏的间接分光光度法,用于测定纯制剂(胶囊、糖浆、片剂)中硫酸沙丁胺醇和甲非那酸的含量。本方法以溴代琥珀酰亚胺在酸性介质中和未反应的氧化剂与一定量的Azur-A染料溶液发生溴化反应为基础,因其漂白其颜色,在606.5 nm处测定了残留色染料的吸光度。对硫酸沙丁胺醇和甲胺酸的摩尔吸光度分别为2.3 × 10 L.mol.cm和8.1× 10 L.mol.cm。硫酸沙丁胺醇在1.6 ~ 12.8 μg/ml范围内、甲胺酸在1.6 ~ 13.6 μg/ml范围内符合比尔定律。两种药物的检出限和定量限分别为0.0367μg/ml和0.1226 μg/ml。回收率在100.56% ~ 100.74%范围内。该方法不涉及任何溶剂提取,具有简单、经济、快速的特点。该方法成功地应用于所研究药物的含量测定。

Enzymatic browning by tyrosinase and nonenzymatic browning (Maillard reaction) are responsible for producing new compounds which contributes considerably to the undesirable of aroma, taste and colour in food . In this study, tyrosinase activity and browning intensity in quince juice were inhibited by treating them with antioxidant compounds vanillin, glutathione and melatonin as compared to the control. The maximum inhibition percentage of Tyrosinase were 83, 68.8 and 90.3 % and the maximum inhibitory effect of browning intensity were 13.9, 9.7 and 29.8% respectively. For untreated quince juice which heated to 5 hours at 100 C, the results showed increasing in A294, Browning intensity (A420) and reducing power, as well as decreasing in reducing sugar, free amino group, phenolic compounds contents and inhibition percentage of lipid peroxidation. The decreasing of A294, browning intensity and increasing in reducing power were showed after treating with (10mM) vanillin and (8mM) glutathione compared to control. Conversely to glutathione, the addition of vanillin to quince juice revealed increasing in inhibition percentage of lipid peroxidation, reducing sugar and phenolic contents and decreasing in free amino acid content compared to control. Inhibition Mode of tyrosinase by melatonin was noncompetitive. The Km value remained constant (1.96mM), while Vmax reduced from 228.13 to 114.06 U.ml.min. Inhibition constant Ki value was 6.9 mM.
酪氨酸酶的酶促褐变和非酶促褐变(美拉德反应)是产生新的化合物的原因,这些化合物对食物的香气、味道和颜色有很大的影响。在本研究中,与对照相比,用抗氧化剂香草醛、谷胱甘肽和褪黑素处理木瓜汁可以抑制其酪氨酸酶活性和褐变强度。对酪氨酸酶的最大抑制率分别为83%、68.8和90.3%,对褐变强度的最大抑制率分别为13.9%、9.7和29.8%。结果表明,未经处理的榅桲汁在100℃下加热5 h后,其A294、褐变强度(A420)和还原力均有所增加,还原糖、游离氨基、酚类化合物含量和脂质过氧化抑制率均有所下降。与对照相比,(10mM)香兰素和(8mM)谷胱甘肽处理后A294的褐变强度降低,还原力增强。与谷胱甘肽相反,加入香兰素对柑汁的脂质过氧化、还原糖和酚类含量的抑制率均高于对照,而游离氨基酸含量则低于对照。褪黑素对酪氨酸酶的抑制模式是非竞争性的。Km值保持不变(1.96mM),而Vmax从228.13 μ m .min降低到114.06 μ m .min。抑制常数Ki值为6.9 mM。
