Authors: Сеничев В.Ю. , Макарова М.А.
Published: January 2024

Not every scientist is able to create a new direction in science. Vasily Vasilyevich Tereshatov was one of those indefatigable laborers who did it. Being ahead of Russian and foreign researchers, he made a major breakthrough in theory and practice of molecular design of block structure polymers in the late 90s – mid 2010s. That made it possible to obtain innovative materials at the world level for the use in defense industry, aviation, oil refining and gas industries.

This article, as well as our previous ones («Vestnik of the Perm Federal Research Center» № 3,      2021, and № 3, 2022), is devoted to the 300th anniversary of the city of Perm (1723–2023), and continues our investigation on the identification of historical personalities who took the active part in the reception of Grand Duchess Elizabeth Feodorovna and her sister – Princess Victoria von Battenberg in Perm in July 1914. As a reminder, in the book, published by the Demidov Institute (Yekaterinburg, 2007), «I.F. Koshko, Memories of the Governor, 1911–1914» there were some mistakes revealed in the representation of personalities in the group photo taken in the garden of the governor's house in Perm. As it turned out, not only V.I. Europeus and A.P. Kornilov, but also many other persons were incorrectly indicated. Since there is no information concerning this photo found in Perm archives and in «Permskie vedomosti» of 1914, we hope our investigation will be interesting not only to local historians, but also to everyone who is interested in history. In the article, we give brief information about each person presented in the photo and, most importantly, provide additional photos confirming the identity of those persons.

Published: January 2024

Cranial nerve palsies can be presenting signs of intracranial aneurysms. There is a classic pairing between an aneurysmal vessel and adjacent nerves leading to cranial neuropathy. Isolated abducens nerve palsy can be a localizing sign of an unruptured vertebrobasilar circulation aneurysm. Aneurysms involving Anterior Inferior Cerebellar Artery (AICA) and Posterior Inferior Cerebellar Artery (PICA) have been reported to be associated with abducens nerve palsy. The symptoms in unruptured aneurysms are due to the mass effect on adjacent neurovascular structures. Most of the abducens nerve palsy resolves following microsurgical clipping. Here, we present a rare case of an unruptured Posterior Cerebral Artery (PCA) aneurysm presenting with abducens nerve palsy and diplopia associated with contralateral hemianopsia which markedly improved following endovascular coil embolization.

Authors: Kumar Bhupendera , Kumar Rajeev
Published: January 2024

In this paper, we attempt to generalize the ability to achieve quality inferences of survey data for a larger population through data augmentation and unification. Data augmentation techniques have proven effective in enhancing models' performance by expanding the dataset's size. We employ ML data augmentation, unification, and clustering techniques. First, we augment the \textit{limited} survey data size using data augmentation technique(s). Next, we carry out data unification, followed by clustering for inferencing. We took two benchmark survey datasets to demonstrate the effectiveness of augmentation and unification. One is on features of students to be entrepreneurs, and the second is breast cancer survey data. We compare the results of the inference obtained from the raw survey data and the newly converted data. The results of this study indicate that the machine learning approach, data augmentation with the unification of data followed by clustering, can be beneficial for generalizing the inferences drawn from the survey data.
Ferredoxin 1 is essential for embryonic development and lipid homeostasis

Published: January 2024

Mammalian ferredoxin 1 and 2 (FDX1/2) belong to an evolutionary conserved family of iron-sulfur cluster containing proteins and act as electron shutters between ferredoxin reductase (FDXR) and numerous proteins involved in critical biological pathways. FDX1 is involved in biogenesis of steroids and bile acids, Vitamin A/D metabolism, and lipoylation of tricarboxylic acid (TCA) cycle enzymes. FDX1 has been extensively characterized biochemically but its role in physiology and lipid metabolism has not been explored. In this study, we generated Fdx1-deficient mice and showed that knockout of both alleles of the Fdx1 gene led to embryonic lethality. We also showed that like Fdxr+/-+/-, Fdx1+/-+/- had a shorter life span and were prone to steatohepatitis. However, unlike Fdxr+/-+/-, Fdx1+/-+/- were not prone to spontaneous tumors. Additionally, we showed that FDX1 deficiency led to lipid droplet accumulation possibly via the ABCA1-SREBP1/2 pathway. Specifically, untargeted lipidomic analysis showed that FDX1 deficiency led to alterations in several classes of lipids, including cholesterol, triacylglycerides, acylcarnitines, ceramides, phospholipids and lysophospholipids. Taken together, our data indicate that FDX1 is essential for mammalian embryonic development and lipid homeostasis at both cellular and organismal levels.

Objectives

To understand the sleep quality and its influencing factors in patients with type 2 diabetes mellitus (T2DM) who suffered diabetic peripheral neuropathy (DPN), and provide evidence for clinicians to carry out comprehensive intervention measures to improve the sleep quality of patients.

Methods

Patients who were admitted to the Endocrinology Department of Affiliated Hospital of Zunyi Medical University were recruited from May to December 2022, and the investigation were conducted by face-to-face interview. The questionnaires included PSQI questionnaire and influencing factors, such as lifestyle and health status.

Results

Among the 193 patients, 40.4% of the patients never took physical examination, 56.5% of the patients had duration of illness greater than 5 years, 61.7% of the patients had had an operation, 10.4% of the patients had bad dietary status, and 55.4% of the patients had physical pain. In addition, the PSQI general score was 8.34 ± 3.98, the occurrence rate of poor sleep quality (PSQI ≥ 8) was 54.4%, and the results showed that sleep quality of the physical pain group was worse than the no pain group. Moreover, the results of multivariate analysis revealed that the factors affecting sleep quality were lower frequency of exercise, bad dietary status, lower frequency of physical examination, longer duration of illness, and smoking, and the OR and 95% CI were [1.40, 1.04∼1.89], [3.42, 1.86∼6.29], [1.49, 1.01∼2.20], [1.78, 1.09∼2.92], [2.38, 1.17∼4.88], respectively.

Conclusion

Patients with DPN have higher risk of poor sleep quality. Moreover, there were many risk factors associated with poor sleep quality, clinicians and health policymakers should timely detect and effectively intervene in these factors to improve the sleep quality, which is important to enhance the quality of life of T2DM patients complicated with DPN.

Published: January 2024

Introduction: There is rising concern about vitamin D deficiency around the globe due to its increasing association with multiple medical disorders. Diabetes Mellitus (DM) is an established risk factor for atherosclerotic disorders, and Carotid Artery IntimaMedia Thickness (CIMT) is considered a radiological marker of subclinical atherosclerosis. Aim: To find a correlation between serum 25-hydroxy vitamin D (25-(OH)-D) levels and CIMT among patients with DM. Materials and Methods: A hospital-based cross-sectional study was conducted, including 100 adult patients with Type 2 DM who were admitted to the Department of Medicine at SCB Medical College and Hospital in Cuttack, Odisha, India from October 2020 to September 2021. Vitamin D deficiency was defined as serum 25-(OH)-D levels <20 ng/mL, and insufficiency as <30 ng/mL. The demographic profile of patients, family history of Type 2 DM, smoking history, blood pressure, haemogram, blood sugar, serum electrolytes, and lipid profile were studied. CIMT of the bilateral Common Carotid Artery (CCA) was measured by B-mode ultrasonography. CIMT values ≥ 0.8 mm were considered abnormal. Data were analysed using appropriate statistical tests in Statistical Packages for Social Sciences (SPSS) version 26.0. Results: The present study included 55% males (n=55) and 45% females (n=45). The average age of the patients was 60 ±10 years, ranging from 26-75 years. Vitamin D deficiency was highly prevalent among patients with Type 2 DM (73% deficient, 12.5 ng/mL; 21% insufficient, 24.7 ng/mL). Vitamin D deficiency/ insufficiency was higher among male participants (57.5%, 62%) compared to females (42.4%, 38%). Vitamin D levels were significantly associated with dyslipidemia. Mean CIMT among the vitamin D deficiency versus insufficiency versus normal group were 0.87 versus 0.87 versus 0.7 mm on the right Common Carotid Artery (CCA), and 0.95 versus 0.86 versus 0.75 mm on the left CCA, respectively. Significant negative correlations were observed for HbA1c (r=-0.025), Triglycerides (r=-0.274), right CIMT (r=-0.284), and left CIMT (r=-0.264) with serum 25-(OH)-D levels. Conclusion: The majority of patients with Type 2 DM have concurrent vitamin D deficiency. A significant inverse linear association between serum vitamin D levels and CIMT was observed, indicating the association of vitamin D deficiency with subclinical atherosclerosis. Although unproven in the present study, the role of vitamin D supplementation in the improvement of atherosclerosis remains unclear.

Published: January 2024

Introduction: Laparoscopic cholecystectomy is now preferred over the open procedure due to advantages such as reduced blood loss and shorter hospital stays. However, concerns have been raised regarding the potential for increased Intra-abdominal Pressure (IAP) during laparoscopic procedures, which may impact haemodynamic stability and respiratory parameters. However, there is a lack of comprehensive analysis directly comparing both surgical approaches from both haemodynamic and capnographic perspectives. Aim: To compare the haemodynamic and capnographic changes between laparoscopic and open cholecystectomy. Materials and Methods: This randomised clinical study was conducted at Department of Anaesthesiology, Assam Medical College and Hospital, Dibrugarh, Assam, India from May 2021 to June 2022. The study included 300 patients scheduled for cholecystectomy, divided into two groups: Laparoscopic Cholecystectomy (LC) Group I (n=150) and Open Cholecystectomy (OC) Group II (n=150). Haemodynamic parameters, including Pulse Rate (PR), Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP), Mean Arterial Pressure (MAP), and Oxygen Saturation (SpO2 ), were recorded. Capnographic parameters, such as End-Tidal Carbon Dioxide (EtCO2 ) levels, were also measured at regular intervals. Data analysis was performed using the student’s t-test and Chi-square test with Statistical Package for Social Sciences (SPSS) version 21.0 software and Microsoft excel. Results: There were no significant differences in age, body weight, and sex distribution between Group I and Group II. However, significant differences were observed in PR and SBP at 15 minutes (PR: 101.46 and 95.86; SBP: 148.57 and 140.97), 30 minutes (PR: 104.52 and 99.82; SBP: 141.28 and 136.07), and 45 minutes (PR: 102.52 and 97.70; SBP: 140.59 and 133.95) (p-value <0.01). Highly significant differences were observed in MAP and EtCO2 postinsufflation at 15 minutes (MAP: 118.38 and 108.61; EtCO2: 36.48 and 33.89), 30 minutes (MAP: 111.11 and 106.01; EtCO2: 41.02 and 36.15), 45 minutes (MAP: 110.73 and 103.48; EtCO2: 42.65 and 38.36), and 60 minutes (MAP: 106.08 and 101.45; EtCO2: 41.10 and 38.21) (p-value <0.01). DBP showed high significance at 15 minutes (103.21 and 93.23), 30 minutes (96.74 and 92.57), and 60 minutes (93.14 and 86.92) (p-value <0.01), and significant (p-value=0.01) at 45 minutes (95.53 and 87.59). Oxygen saturation showed significance (p-value <0.05) at 15 minutes (99.93 and 100). Conclusion: The present study demonstrated a significant increase in both haemodynamic and capnographic parameters, even in American Society of Anaesthesiologists (ASA) Grade-I and Grade-II patients undergoing laparoscopic cholecystectomy compared to the open surgical technique. These findings emphasise the need for careful monitoring during laparoscopic procedures.

Published: January 2024

Vinegars are the product of scalar fermentations carried out by several groups of microorganisms acting at different moments in time. Apple vinegar is made with apple juice or concentrated Apple juice (CAJ) through a double fermentation: alcoholic and acetic. Vinegar was successfully produced from the juice extracted from pear using yeast and acetic acid bacteria. This study presents a summary of research concerning the quality of vinegar made from pear and apples by using double distillation method. Juice is extracted from both the apple and pear and was analysed for several parameters like pH, brix, specific gravity, Total Reducing Sugars (TRS), Reducing Sugars (RS), titratable acidity, alcohol percentage and Total Dissolved Solids (TDS). pH of pear and apple juice was found to be 4.82 and 4.35 respectively. pear and apple juice had the Brix of 8.5° and 12° respectively. The TRS of pear and apple juice was found to be 10.2%and 11.87 % respectively. Quality characteristics between pear vinegar and apple vinegar were investigated which includes pH, titratable acidity and alcohol percentage. The alcohol percentage of pear vinegar is slightly less than apple vinegar but the titratable acidity of pear vinegar was slightly more as compared to apple vinegar. Also pH of pear vinegar and apple vinegar are found to be 3.60 was 3.58 respectively. Acetic acid bacteria were isolated from Pear and apple vinegar prepared, using Frateur medium and Glucose Yeast Peptone (GYP) agar medium. Aceto Acetic Bacteria (AAB) isolated was confirmed to be Gram negative rods through Grams staining. The study reveals that pears being a seasonal fruit and cheaper compared to apples can be used to prepare healthy vinegar of best quality by a simple double fermentation method.

Published: January 2024

Background: Cardiovascular disease (CVD) is the primary cause of all disease loads and accounts for almost half of all fatalities. The early detection of coronary artery disease (CAD) has drawn a lot of attention because it is anticipated that the global burden of cardiovascular disease will rise by almost 75% by 2020. They are easily oxidized, which causes an increase in affinity for arterial proteoglycans and a decrease in affinity for LDL receptors. It demonstrates significant CAD importance.

Objective: The measurement of plasma lipid profiles and apolipoproteins (ApoA-1, ApoB, and Apo B/A-1 ratio) in healthy individuals and patients suffering from coronary artery disease.

Methods: In this cross-sectional comparative study, 90 Yemeni subjects aged 45 to 70 years were divided into three groups: Group I: 30 cases as CAD positive (CAD+). Group II: 30 cases CAD negative (CAD -). Group III: 30 healthy person was as control. A standardized questionnaire was administered to collect demographic and clinical data from participants. Venous blood (10 ml) was collected from each individual and divided into two portions. The first portion was 5 ml in plain tubes, ApoA-1 and Apo B vacuum tubes for freezing at -20°C until analysis. 5ml in a plain tube for measuring fasting blood glucose, and lipid profile.

Results: ApoB and Apo B/A ratios were significantly higher in CAD+ and CAD− subjects compared to controls. In addition, ApoB and Apo B/A ratios were significantly higher in CAD+ subjects compared to CAD- subjects. (P. value =0.002). In contrast, Apo A-1 was significant in CAD+ compared to CAD- and controls, and not significantly different between CAD and controls P. value = (0.001, 0.032). Furthermore, FBS and LDL-c were significantly higher in CAD+ compared to CAD subjects (P value = 0.05). In contrast, HDL-c was significantly lower in CAD+ compared to CAD and controls, with no significant difference between CAD and controls (P value=0.038, 0.004, 0.70). However, TG was not substantially different between CAD- and controls, but it was significantly greater in CAD+ compared to controls (P. value =0.002, 0.09, 0.31). Nevertheless, there was no difference in TC between study groups (P. value = 0.08, 0.12, 0.98).

Conclusions: The degree of CAD is significantly positively correlated with WHR. More important than overall obesity, abdominal obesity is a risk factor for coronary heart disease (CHD). A significant positive connection has been observed between the Apo B/Apo A ratio and CAD. One thing to think about as a CAD risk factor is Apo B.

Published: January 2024

Rice root-knot nematode, Meloidogyne graminicola is one of the most serious nematode pest associated with rice throughout the world. With other species of root-knot nematode, M. graminicola can also infect wide range of weed flora which is commonly grown in or near the rice field. To study the alternate weed hosts of M. graminicola a survey was conducted in the major rice growing blocks of Fatehabad and Sirsa districts of Haryana during Kharif season 2022. A total of 726 samples were collected from rice fields, both from transplanted (TR) and direct seeded rice (DSR) from Phoolan, Bharpur, Ratta Khera, and Jandwala Sotter villages of Fatehabad and Bahauddin and Sikanderpur, Dhottar, Ding and Chopta villages of Sirsa. Out of which 353 samples were found free from nematode infestation while 373 samples (209 from DSR and 164 from TR)were found infested. The juveniles and galls were recorded ranging from 4-190 on the roots of different weed plants. Hence, it is concluded from the present investigation, that nematodes favor more DSR and its weed flora than TR for infection and survival.

Authors: Motta Raíssa Coelho , Hanna Samira Abdallah
Published: January 2024

O desperdício de alimentos é exacerbado por questões logísticas que resultam na perda entre colheita e varejo, afetando a sustentabilidade dos sistemas alimentares com impactos socioeconômicos e ambientais. A pesquisa e o desenvolvimento de matérias-primas, insumos e tecnologias na embalagem e transporte de alimentos podem reduzir perdas. Embalagens ativas podem ser estratégicas, pois além de conter os produtos, incorporam agentes que melhoram características sensoriais prolongando a vida útil dos alimentos. Este estudo apresenta uma visão das embalagens ativas para alimentos com eugenol, composto natural com atividade antioxidante e antimicrobiana, em informações de artigos científicos (plataforma SciELO®) e patentes (plataforma Espacenet®). Indústrias americanas (setores de biotecnologia, estética, farmacêutica e instrumentos analíticos) são as principais detentoras das patentes. A maioria delas concentra-se em C11D3/505 (substâncias aromáticas encapsuladas). O desenvolvimento de embalagens ativas com eugenol tem potencial inovador e está alinhado aos Objetivos de Desenvolvimento Sustentável (ODS) propostos pela Organização das Nações Unidas (ONU).

Published: January 2024

Os produtos e as embalagens poliméricas estão no centro da discussão sobre o que é denominado “poluição plástica” em razão das evidências dos impactos ambientais causados nos ecossistemas. Não obstante, as unidades de triagem de resíduos recicláveis (UTRR) nas cidades têm recebido cada vez mais embalagens poliméricas de difícil reciclabilidade dificultando a sua comercialização e encaminhamento desses materiais para reciclagem. O referido estudo buscou identificar quais são os tipos de resíduos sólidos urbanos (produtos e suas embalagens poliméricas), que estão resultando em rejeito em três unidades de triagem de resíduos recicláveis (UTRR) e em uma Central de Transbordo e Triagem (CTT) localizadas em 3 municípios do Rio Grande do Sul, Porto Alegre, Novo Hamburgo e Santiago, bem como conhecer o tipo do produto dessas embalagens, o tipo do material e a classificação dessas resinas. Os principais resultados apontaram que a grande maioria das embalagens que estão resultando em rejeitos nessas unidades são de origem de produtos alimentares, com 84 % (341 embalagens de um total de 405). Quanto aos tipos de materiais, destaca-se o tipo sem identificação (SI) representando 42 % da amostragem (169 embalagens de 405), seguido do Polipropileno (PP) com 24 % (99 embalagens de 405) e Outros (O) com 22 % (90 embalagens de 405). Tais resultados também à tona que muitas embalagens poliméricas não estão seguindo a identificação e simbologia conforme a NBR 13.230, e portanto, não estão sendo classificadas, dificultando o seu encaminhamento para a reciclagem.

EDUCAÇÃO SEXUAL À LUZ DO PRINCÍPIO DA DIGNIDADE DA PESSOA HUMANA
Authors: Simas Magno Thiago Logan , Tavares de Albuquerque Ricardo
Published: January 2024

A violação de direitos individuais de homossexuais e transexuais está vinculada a um processo histórico e cultural que incita a hostilidade contra os sujeitos que não cumpram os padrões estabelecidos de sexualidade e gênero. A escola pode ser ferramenta de transformação desse cenário, a partir da formação de estudantes que respeitem à diferença, por meio da educação sexual. À vista disso, sob a perspectiva jurídica, cumpre investigar se essa pedagogia relaciona-se com a dignidade da pessoa humana, protegendo-a ou promovendo-a, razão pela qual deve ser implementada em virtude da importância conferida à dignidade pelo ordenamento jurídico. Com base no método dedutivo, chegou-se à conclusão que existe uma conexão entre a dignidade da pessoa humana e a educação sexual, o que fundamenta sua incorporação ao ordenamento jurídico pátrio, a ser elucidada no decorrer do presente artigo.
The incidence of gains and taxes associated with R&D and promotion in the Australian beef industry
Authors: Zhao Xueyan , Mullen John , Griffith Garry , Piggott Roley , Griffiths William
Published: June 2003

This article reports the incidence on cattle producers, feedlotters, processors, marketers, and domestic and overseas consumers of benefits and levies associated with 12 alternative research and promotion options using a partial equilibrium displacement model (EDM) of the Australian beef industry. The results showed that, in terms of their share of total industry benefits, cattle producers would prefer farm research to off‐farm research; export marketing research and promotion to domestic marketing and promotion; and farm research to domestic (but not export) promotion. The article has also explored some of the methodological issues associated with the detailed modeling of a multifaceted industry. Despite the high level of disaggregation, we found EDM to be a useful methodology. [EconLit citations: Q13, Q16, Q18]. © 2003 Wiley Periodicals, Inc. Agribusiness 19: 333–344, 2003.
Who bears the burden and who receives the gain?—The case of GWRDC R&D investments in the Australian grape and wine industry
Authors: Zhao Xueyan
Published: June 2003

It is only when R&D levies are invested in the sectors in which they are raised that the distribution of the benefits among industry sectors is exactly the same as the incidence of the levies. This article examines the distributions of both costs and returns from the Australian grape and wine R&D investments and the divergence between the two distributions. The real shares of R&D costs are estimated through the incidence of the levies and compared with the nominal shares. Grape‐growers, winemakers and overseas consumers are shown to receive bigger proportions of gains than their proportions of costs, while the Australian government and other domestic parties as a group bear a much higher proportion of costs than returns. This article discusses implications of results for the equity issue between premium and nonpremium producers, the free‐rider issue for overseas consumers, and the justification of government funding of grape and wine R&D.

Measures of precision for estimated welfare effects for producers from generic advertising
Authors: Piggott Nicholas E.
Published: June 2003

Using a multi‐market equilibrium displacement model (EDM) framework, the precision of market parameters (elasticities) measured using econometric methods, can be combined with prior beliefs from economic theory, to calculate how precisely changes in producer welfare from generic advertising are estimated. This EDM approach enables the benefits and costs of simulated small changes in the checkoffs and advertising on producer welfare to be measured. To calculate the associated precision for changes in producer welfare measures, Monte Carlo integration is used, in a Bayesian approach, imposing inequality restrictions from theory, to generate empirical posterior distributions of the changes in producer welfare measures. These empirical distributions can be used to place confidence intervals around the posterior means and to test whether estimates are statistically significantly different from zero. Alternatively, the probability that a welfare measure change is greater than zero can be calculated, which may serve to even be more informative.

Adhesion and permeability of polyimide–clay nanocomposite films for protective coatings
Authors: Khayankarn Orasa , Magaraphan Rathanawan , Schwank Johannes W.
Published: June 2003

A polyimide (PI)–clay nanocomposite was prepared from a solution of poly(amic acid), a precursor of 2,2‐bis[4‐(3,4‐dicarboxyphenoxy)phenyl]propane dianhydride and p‐phenylenediamine, and dodecylamine–montmorillonite. Fourier transform infrared spectroscopy, thermogravimetric analysis, X‐ray diffraction, and atomic absorption spectroscopy were used to verify the incorporation of the modifying agents into the clay structure and the intercalation of the modified clay into the PI matrix. Both PI and PI–clay films were subsequently prepared by solution casting. The gas permeability, resistivity, and adhesion properties were determined. In the case of gas permeability, only a 3 wt % addition of clay reduced oxygen permeability to less than half that of unfilled PI. Furthermore, this hybrid showed an improvement in electrical resistivity because of the prevention of electrical tree growth by clay particles. More importantly, adhesion between the films and silicon increased with increasing clay content. © 2003 Wiley Periodicals, Inc. J Appl Polym Sci 89: 2875–2881, 2003
Polyglycolide‐based blends for drug delivery: A differential scanning calorimetry study of the melting behavior
Authors: Dickers Kirsten J. , Huatan Hiep , Cameron Ruth E.
Published: June 2003

The melting behavior of polyglycolide (PGA) with eight other biodegradable polymers was investigated to determine whether forming a blend could be used as a method of lowering the melting point of PGA. Blends were prepared by melt processing in differential scanning calorimetry (DSC) pans and were then analyzed by DSC. In every case, a comparison of the blend DSC plot with those of the two individual components showed that the melting behavior of PGA remained unchanged by blending. © 2003 Wiley Periodicals, Inc.

Polyelectrolytes from NS‐novolak production waste
Authors: Bajdur Wioletta M. , Sułkowski Wiesław W.
Published: June 2003

The chemical modification of polymer plastic wastes into useful products, such as polyelectrolytes, could be a step toward their management. For these products to be obtained, the synthesis of amino derivatives of phenol‐formaldehyde resin (NS‐novolak) production waste by means of known methods was performed. Products that contained different contents of amino groups in the polymer chains and that were soluble in dilute KOH and NaOH solutions were obtained. The flocculation properties of these products were tested. Studies were conducted of mine water from the Kleofas coal mine and for water from the Częstochowa metallurgical plant blast‐furnace circulation system. The amino derivatives of the phenol‐formaldehyde resin waste were found to have good flocculation properties. The application of these products caused a decrease in the turbidity and concentration of the dissolved contamination and improved the quality parameters of the purified sewage. These polyelectrolytes could also be used in industrial water treatment. © 2003 Wiley Periodicals, Inc. J Appl Polym Sci 89: 3000–3005, 2003
Application of chemiluminescence to probe miscibility in metallocene‐catalyzed polyethylene blends
Authors: Cran Marlene J. , Fearon Peter K. , Billingham Norman C. , Bigger Stephen W.
Published: June 2003

Chemiluminescence (CL) monitoring has successfully been applied to the study of the oxidative degradation of two‐component polyethylene blends made with commercially available low‐density polyethylene, linear low‐density polyethylene, high‐density polyethylene, and metallocene‐catalyzed linear low‐density polyethylene (mLLDPE) formulations. The emphasis in the analysis of the results is placed on blends containing mLLDPE to address the lack of CL information on these blends. The CL data are consistent with the thermal and physicomechanical properties of the blends, with a decreased blend miscibility being reflected in the CL data as a departure from the idealized behavior observed for more miscible blends. Furthermore, the results suggest that immiscibility in the solid state is reflected to some extent in the behavior of the melt. Preliminary experiments conducted to determine the level of consistency of CL results with respect to both variability between instruments and variability between techniques indicate a high degree of correlation in each case. © 2003 Wiley Periodicals, Inc.

Synthesis and properties of amphiphilic copolymers of butyl acrylate and methyl methacrylate with uniform polyoxyethylene grafts
Authors: Xie Hong‐Quan , Liu Xin‐Hua , Guo Jun‐Shi
Published: June 2003

Amphiphilic copolymers of butyl acrylate (BA) and methyl methacrylate (MMA) with uniform polyoxyethylene (PEO) grafts were synthesized by the copolymerization of BA and MMA with a methacrylate‐terminated PEO macromer in benzene with azobisisobutyronitrile as an initiator. The effects of various copolymerization conditions on the grafting efficiency and molecular weight of the copolymers, as well as the effect of the copolymerization time on the conversions of the macromer and the monomers, were reported. The copolymers, with uniform PEO grafts, were purified by successive extractions with water and ether/acetone (3/7) to remove unreacted macromer and ungrafted copolymers of MMA and BA, respectively. The purified graft copolymers were characterized with IR, 1H‐NMR, membrane osmometry, gel permeation chromatography, and differential scanning calorimetry. The highest grafting efficiency was about 90%, and molecular weight of the copolymers varied around 105. The average grafting number of the copolymer was about 10. A study of the crystalline properties, emulsifying properties, phase‐transfer catalytic ability, and mechanical properties of the graft copolymers showed that the emulsifying volume decreased with the increasing molecular weight of the PEO grafts but increased with the PEO content. The conversion of potassium phenolate in the Williamson solid–liquid reaction obviously increased with an increasing PEO content of the graft copolymers. The crystallinity of the graft copolymers increased with the PEO content of the graft copolymers or the molecular weight of the macromer used. The copolymers, prepared under certain conditions, behaved as thermoplastic elastomers. © 2003 Wiley Periodicals, Inc. J Appl Polym Sci 89: 2982–2988, 2003
Enantioselective permeation of α‐amino acid optical isomers through crosslinked sodium alginate membranes
Authors: Hoon Kim Jang , Jegal Jonggeon , Hye Kim Jee , Lee Kew‐Ho , Lee Yongtaek
Published: June 2003

A pressure‐driven separation process, using self‐supporting crosslinked sodium alginate (SA) membranes with different swelling indices, enabled the optical resolution of α‐amino acids, including the optical isomers of tryptophan and tyrosine. The SA membranes were prepared by the casting and drying of SA solutions on an acryl plate, followed by crosslinking with glutaraldehyde. They were characterized with analytical methods, such as Fourier transform infrared and swelling index measurements. During optical resolution with the SA membranes, the effects of experimental factors were studied, such as the concentration of the feed solutions, the operating pressure, and the degree of crosslinking of the membranes. When an SA membrane with a swelling index of 80% was used, a good optical resolution of tryptophan isomers was obtained: an enantiomeric excess of 54.0% and a flux of 24.8 mg/m2 h. © 2003 Wiley Periodicals, Inc.

Published: June 2003

Syndiotactic polystyrene (sPS) membranes containing different mole fractions of p‐xylene were prepared by a solution‐casting procedure. Complex formation between sPS and xylene was studied by thermogravimetric analysis and Fourier transform infrared spectroscopy. The stability and desorption behavior of the sPS–guest solvent and phase transitions were studied by differential scanning calorimetry. The formation of the δ‐form complex in the presence of different mole fractions of xylene isomers was analyzed and confirmed. The mole fraction of p‐xylene in the dried membrane was found to be higher than that of the corresponding mole fraction in the isomer solvent solution used for casting. This was attributed to the preferential complexing ability of p‐xylene with sPS. © 2003 Wiley Periodicals, Inc. J Appl Polym Sci 89: 2882–2887, 2003

Published: June 2003

A new copolymer, referred to as poly(phenylene‐vinylene) (PPV)‐ether, built as PPV a polymer with some (CHCH) links changed into (CH2 OCH2) ethylic‐ether links, is insoluble in common solvents. PPV‐ether films are deposited by the thermal evaporation technique. X‐ray photoelectron spectroscopy for chemical analysis measurements indicate that the surface contamination decrease in the case of vacuum‐evaporated PPV‐ether. The scanning electron micrographs indicate that the surface of these vacuum‐deposited PPV‐ether are uniform. By comparison to the reference powder, the modification of the properties of the evaporated PPV‐ether are related to the decrease of the chain length and surface contamination. The results of the photoluminescence measurements reveal a shifting of the luminescence to blue in the vacuum‐evaporated PPV‐ether. © 2003 Wiley Periodicals, Inc. J Appl Polym Sci 89: 3091–3099, 2003
