作者： stanley I. sandler

ISBN: (纸本)9780471661740

A modern, accessible, and applied approach to chemical thermodynamics Thermodynamics is central to the practice of chemical engineering, yet students sometimes feel that the discipline is too abstract while they are studying the subject. By providing an applied and modern approach, stanley sandler's Chemical, Biochemical, and Engineering Thermodynamics, Fourth Edition helps students see the value and relevance of studying thermodynamics to all areas of chemical engineering, and gives them the depth of coverage they need to develop a solid understanding of the key principles in the field. Key Features Highlights applications of thermodynamics to subjects that chemical engineering students will see in later courses. Realistic problems introduce students to the types of challenges they will encounter in industry and graduate research. The Fourth Edition has been reorganized into 15 chapters, providing shorter chapters that introduce students to the subject in more bite-sized pieces. Presents biochemical examples, particularly in Chapters 11 and 12, and in all of Chapter 15 entitled "Biochemical Applications of Thermodynamics." Coverage of environmental and safety applications of thermodynamics provides course material useful for ABET accreditation. Includes a brief introduction to the new field of product engineering in Chapter 12. Instructional objectives and nomenclature lists at the beginning of each chapter provide useful study tools. students can solve problems using MATHCAD(r), MATLAB(r) and Visual Basic programs that accompany this textbook. An accompanying CD features a 120-day trial version of MATHCAD, as well as MATHCAD worksheets, an extensive properties database, and Windows-friendly Visual Basic and MATLAB programs for equation of state and UNIFAC calculations. (These worksheets and programs are also available online at the book website.) Also included on the CD are PDF files of important data figures that students can download and print for use

Background: The nutritional status of women while in pregnancy influences foetus growth, infant development, and the mother’s health. The objective of this study was to assess diet quality and associated factors among women of childbearing age in the Comè community, Benin. Methods: The cross-sectional and analytical study involved 215 participants randomly selected by multi-stage sampling technique. Two non-consecutive dietary recall data were collected as well as sociodemographic information. The International Food Quality Index (IQD-I) was used to assess diet quality. Factors associated with the nutritional quality of the diet were identified by using linear regression. Results: Among 212 women, a diet quality of 175 (82.55%) was fair while 14.62% had good diet quality. Factors associated with the diet quality were the level of household possession, health issues, and nutritional advice at the health care facilities. Conclusion: Nutritional education interventions and income-generating activities may improve the diet quality among women of childbearing age in the Comè in Benin.

Prevention of Maternal Low-Grade Chronic Inflammation: The Diet’s Inflammatory Potential in Pregnant Women in southern Benin

引用

Open Journal of Preventive Medicine 2023年第9期13卷 257-270页

作者： Charles sossa Jerome Lamidhi salami Farida seydou Clemence Metonnou colette Azandjeme Moussiliou N. Paraiso Department of Health Promotion Regional Institute of Public Health University of Abomey-Calavi Ouidah Benin Department of Health Policy and systems Regional Institute of Public Health University of Abomey-Calavi Ouidah Benin

Background: Pathogenic mechanisms link maternal systemic low-grade chronic inflammation to intrauterine development. A pro-inflammatory diet during pregnancy is associated with chronic maternal systemic inflammation. The objective of the study was to determine the diet inflammatory index and identify associated foods and nutrients in pregnant women of Ouidah city, Benin. Methods: The cross-sectional study conducted among pregnant women randomly selected by cluster sampling. Nutrient intakes and food consumed were estimated based on data of two 24-hour non-consecutive recalls. The inflammatory weightings of each nutrient were used to calculate the diet inflammatory index for each pregnant woman. Results: The average age of the 310 pregnant women surveyed was 27.20 ± 5.99 years. The median diet inflammatory index was -3.026 (-16.59;1.86). The pregnant women with inflammatory diet accounted for 11.30%. Vitamin A and zinc were negatively correlated with the diet inflammatory index. Fruits, roots, tubers and sweetened drinks consumed were positively correlated with the diet inflammatory index. On the contrary, the quantities of cereals, vegetables, legums and fish consumed were negatively correlated with the diet inflammatory index. Conclusion: More than one pregnant woman out of ten in the Ouidah city had a pro-inflammatory diet. Reducing maternal systemic low-grade chronic inflammation may include increasing the consumption of identified anti-inflammatory foods.

American Journal of Plant sciences 2019年第12期10卷 2335-2353页

salinity is one of the major environmental constraints limiting agricultural productivity in the world. The effects of salt stress on growth, ions and organic solutes accumulation were investigated in two amaranth (Amaranthus cruentus) cultivars: Rouge (salt-resistant) and Locale (salt-sensitive). Young plants of these cultivars were exposed, in hydroponic system, to three concentrations of NaCl: 0, 30 and 90 mM. Growth parameters, ions, free proline and soluble sugars concentrations were determined after 2 weeks of stress. NaCl effect resulted in plant growth reduction in both cultivars but plants of cultivar Rouge were less affected compared to that of cv. Locale. Na+, proline and soluble sugars concentrations increased significantly in leaves and roots under salinity while K+, Ca2+ and Mg2+ concentrations decreased in both cultivars. Proline and soluble sugars increased significantly in leaves and roots of cultivar Locale whereas in cultivar Rouge, proline increase was significant only in roots and soluble sugars increase was significant only in leaves. The highest increase of Na+ concentration occurred in leaves of cv. Rouge coupled with the lowest reduction in K+ concentration. The highest increase of proline occurred in leaves of cultivar Locale whereas the highest increase of soluble sugars was observed in leaves of cultivar Rouge. The reduction of the Ca2+ concentration under salt stress was more accentuated in both leaves and roots of cultivar Rouge than cultivar Locale while cv. Rouge maintained higher content in Mg2+ either in leaves or in roots in the presence of NaCl than cultivar Locale. These results suggest an implication of Na+, K+ and Mg2+ in salt resistance in these cultivars and that soluble sugars may play an important role in salt-resistance in Amaranthus cruentus. However, proline appears as a symptom of injury in stressed plants rather than an indicator of resistance.

Introduction: Gastroesophageal Reflux Disease (GERD) is a common benign condition with a worldwide prevalence of between 5% and 45% in the adult population. Its prevalence in the general population is little known in Africa. The aim of this work was to study the prevalence of typical GERD in the general adult population of a large city and the associated socio-demographic factors. Patients and Methods: This was a prospectively collected, descriptive and analytical cross-sectional study that was conducted over a one-month period (June 2018). We included any person residing in the city of Cotonou for at least 6 months, aged 15 years or older, who had given consent for the study. The two-stage cluster sampling technique was used. The dependent variable was the typical gastroesophageal reflux defined by the heatburn-regurgitation association. Results: We had included 728 suspan>bjects. Of these, 255 had a typical GERD, i.e. a prevalence of 35%. The mean age of the respondents was 31.9 ± 13.2 years with extremes of 15 and 88 years. There were 379 men (52.1%) with a sex ratio of 1.08. The study population was represented respectively by artisans (29.3%), students (26.6%) and traders/dealers (20.3%). In terms of marital status, there were as many married and single subjects (48.2%). In addition, 47% of the study population had a body mass index of less than 25 kg/msup>span style="font-family

Forecasting Foreign Direct Investment to Zambia: A Time series Analysis

引用

Open Journal of statistics 2017年第1期7卷 122-131页

作者： stanley Jere Bornwell Kasense Obvious Chilyabanyama Department of Mathematics and statistics Mulungushi University Kabwe Zambia

Three methods are considered in this paper: simple exponential smoothing (sEs), Holt-Winters exponential smoothing (HWEs) and autoregressive integrated moving average (ARIMA). The best fit model was then used to forecast Zambia’s annual net foreign direct investment (FDI) inflows from 1970 to 2014. Foreign direct investment is foreign capital investment to Zambia. Throughout the paper the methods are illustrated using Zambia’s annual Net FDI inflows. A comparison of the three methods shows that the ARIMA (1, 1, 5) is the best fit model because it has the minimum error. Forecasting results give a gradual increase in annual net FDI inflows of about 44.36% by 2024. Forecasting results plays a vital role to policy makers. Decision making, coming up with good policies and suitable strategic plans, depends on accurate forecasts. Zambian FDI policy makers can use the results obtained in this study and create suitable strategic plans to promote FDI.

In-situ gelation of aqueous sulfomethylated resorcinol formaldehyde (sMRF) system inBerea core has been investigated. Two sets of displacement experiments were conducted with thissystem (containing 5% NaCl, 0. 036% CaCl_2. 2H_2O). The brine permeabilities of the coreswere reduced significantly from about 600 to 0.1 md. The in-situ gelation in Berea core occurreda little bit earlier than gelation anticipated from bulk test in the experiments. The gel time waseasier to control at initial pH between 6 and 8. During injection of sMRF system, the apparentviscosity was less than 1 mPa·s at 41℃.

A NOVEL EOR POLYMER (Ⅰ)—sTUDY ON GELATION OF REsORCINOL-FORMALDEHYDE sYsTEMs

引用

Chinese Journal of Polymer science 1995年第1期13卷 59-65页

作者：庄银凤 stanley McCool G.Paul Willhite Don W.Green Department of Material Engineering Zhengzhou UniversityZhengzhou 450052China The Tertiary Oil Recovery Project The University of Kansas Lawrence KS 66045U. S. A.

Factors affecting the gelation of resorcinol-formaldehyde systems have been examined overvariable ranges applicable to oilfield use. Gelation of resorcinol-formaldehyde (RF) system wassensitive to pH,salinity and hardness. Generally,this gel system could be used in fresh water orlow salinity brine at pH higher than about 9. The application would require careful monitoring ofinjection fluids to avoid premature gelation or prolonged shut-in times,especially under conditionsof low salinity and high pH. salinity and hardness compatibilities of the system were improved bysulfomethylation of resorcinol. Aqueous sulfomethylated resorcinol formaldehyde (sMRF)system could be used in brine with higher salinity and hardness and at a wider pH range of 5--10.

Hate springs Eternal

引用

国际经济合作 2007年第10期 1-1页

作者： stanley Bing

some years ago I worked on a merger between my company and another-although, in my opinion, there is no such thing as a merger. There is only a process by which one company gobbles up a competitor. sometimes it's a big fish downing a little one. On other occasions, a tiny fish with big leverage swallows an entity ten times its size, like a snake eating a boar.
