description: A new series of cationic surfactants, N–alkyl–N,N–dimethyl–N–(p–(hydroxymethyl) benzyl) ammonium chlorides (p-DHBA-m), were synthesized and the structures were characterized by 1HNMR, 13CNMR, FT–IR and ESI–MS. The surface activities, thermodynamic properties and aggregation behaviors of p-DHBA-m in aqueous solutions were respectively studied by means of surface tension, isothermal titration calorimetry and steady-state fluorescence methods. Thermodynamic parameters show that the micellization is an entropy-driven process. According to the fluorescence quenching method, the micelle aggregation numbers (Nagg) of p-DHBA-m were calculated and found that the increase of temperature or the elongation of alkyl chain length could lead to the reduction of the Nagg, respectively.

description: This work introduces, for the first time worldwide, molasses – a byproduct of the sugar industry – as a master retention aid and strength promoter in papermaking. The paper nanocomposites produced in the present work – involving molasses, natural cellulose fibers, and kaolin – retained larger amounts of kaolin while exhibiting greater strength, as compared to their molasses-free counterparts. Recently, the authors have shown, for the first time, that the nanoadditive sucrose can overcome the ultimate fate of deterioration in strength of paper, due to addition of inorganic fillers such as kaolin. This deterioration was counteracted by incorporating the nanoporous structure of cellulose fibers with sucrose, which leads to incorporation beating of the fibers, and thus increases the strength of the produced paper nanocomposites. In addition, the nanoadditive sucrose was proven – for the first time – to act as retention aid for inorganic fillers such as kaolin. We called this phenomenon incorporation retention to differentiate it from the conventional types of retention of inorganic fillers. On the other hand, it is well established in the literature that using gums (including starch) as additives in papermaking enhances the strength of paper. Molasses contains both the nanoadditive (sucrose), and gums (including starch). Molasses is a byproduct of sugar industry, which is cheaper than sucrose; and a major part of sucrose lost in sugar industry resides in molasses. Moreover, molasses is an environmentally safe additive. Therefore, the nanoadditive (molasses) was chosen, in the present work, to be manipulated as a master strength promoting retention aid for inorganic fillers used in papermaking, such as kaolin.

description: article explores the use of the Waterfall methodology in project management, focusing on its structure, advantages, disadvantages, and ongoing relevance in specific industries. As a linear, sequential process, Waterfall is widely applied in fields that require rigorous planning, documentation, and regulatory compliance, such as construction, aerospace, and government projects. Despite the rise of Agile, which offers greater flexibility and adaptability, Waterfall remains crucial where predictability and control are essential. The paper examines how Waterfall's strict phase-based approach benefits projects needing a clear, well-documented process, especially when deviations are costly. Additionally, the article discusses emerging hybrid models that combine Waterfall's predictability with Agile's flexibility to better handle dynamic project environments.

description: To adjust the properties of the macromolecular structure of cellulose, chemical modification can take place to find different applications. In the current study, cellulose was extracted from bagasse, where it was derivatized to carboxymethyl cellulose, and carbanilated cellulose. These two cellulose derivatives were further chemically modified in homogenous system by tosyl and trimethylsilylation to synthesize cellulose macromolecular derivatives, namely tosylcellulose derivatives and trimethylsilylcellulose derivatives. The compositional microstructure of the synthesized cellulose derivatives was investigated by 1 HNMR analysis, FT-IR and SEM. This study demonstrated that cellulose, cellulose derivatives and both tosyl and trimethylsilyl cellulose derivatives formed under homogeneous conditions can be evaluated as potential carriers for controlled release of anti-acid drugs. The release was investigated as a function of pH and time in various pH solutions, namely 2.0, 3.5 and 5.0. The results indicated that the release is controlled by the type of the modified cellulose and thus it was concluded that modification is important for the use in slow drug release.

description: This work introduces, for the first time worldwide, an advanced nanocomposite involving two additives – a nanoadditive and a conventional additive – within a matrix of natural cellulose fibers. The first additive (the nanoadditive) is sucrose, which incorporates the nanoporous structure of the cell walls of cellulose fibers. The second additive (the conventional additive) is kaolin, the famous paper filler. Kaolin is enmeshed between the adjacent cellulose fibers. This advanced paper nanocomposite was prepared by simple techniques. The present work shows, for the first time, that sucrose can overcome the ultimate fate of deterioration in strength of paper, due to addition of inorganic fillers such as kaolin. This deterioration was counteracted by incorporating cellulose fibers with sucrose, which leads to incorporation beating of the fibers, and thus increases the strength of the produced paper nanocomposites. In addition, sucrose was proven – for the first time – to act as retention aid for inorganic fillers such as kaolin. We called this phenomenon incorporation retention to differentiate it from the conventional types of retention of inorganic fillers. Recent studies, by the authors and others, have shown that incorporating cellulose fibers, with sucrose, leads to paper nanocomposites of enhanced strength (breaking length). Also, sucrose is privileged by its small size (0.8 nm), substantial hydrogen bonding capacity, low cost, and abundance. Therefore, sucrose was chosen as a nanoadditive in this work. The present study shows that the nanoadditive sucrose may find its use as a new retention aid and strength promoter in papermaking.

description: Available formulations of sumatriptan succinate (SS) have low bioavailability or are associated with site reactions. We developed various types of self-dissolving microneedle arrays (MNs) fabricated from sodium hyaluronate as a new delivery system for SS and evaluated their skin permeation and irritation in terms of clinical application. In vitro permeation studies with human skin, physicochemical properties (needle length, thickness and density), and penetration enhancers (glycerin, sodium dodecyl sulfate and lauric acid diethanolamide) were investigated. SS-loaded high-density MNs of 800 µm in length were the optimal formulation and met clinical therapeutic requirements. Penetration enhancers did not significantly affect permeation of SS from MNs. Optical coherence tomography images demonstrated that SS-loaded high-density MNs (800 µm) uniformly created drug permeation pathways for the delivery of SS into the skin. SS-loaded high-density MNs induced moderate primary skin irritations in rats, but the skin recovered within 72 h of removal of the MNs. These findings suggest that high-density MNs of 800 µm in length are an effective and promising formulation for transdermal delivery of SS. To our knowledge, this is the first report of SS permeation across human skin using self-dissolving MNs.

description: Short-cut nitrification (SCN) is shown to be an attractive technology due to its savings in aeration and external carbon source addition cost. However, the shortage of excluding nitrite nitrogen as a model state in an Activated Sludge Model limits the model predictive control of biological nitrogen removal via SCN. In this paper, a two-step kinetic model was developed based on the introduction of pH and temperature as process controller, and it was implemented in an SBR reactor. The simulation results for optimizing operating conditions showed that with increasing of dissolved oxygen (DO) the rate of ammonia oxidation and nitrite accumulation firstly increased in order to achieve a SCN process. By further increasing DO, the SCN process can be transformed into a complete nitrification process. In addition, within a certain range, increasing sludge retention time and aeration time are beneficial to the accumulation of nitrite. The implementation results in the SBR reactor showed that the data predicted by the kinetic model are in agreement with the data obtained, which indicate that the two-step kinetic model is appropriate to simulate the ammonia removal and nitrite production kinetics.

description: Finding new uses for recycled paper (a cellulose rich raw material), and increasing the rate of recycling is beneficial to the environmental efficiency of the whole paper industry. The present work introduces, for the first time, deinked recycled old newsprint as a new resource of electrical purposes paper. Impregnation of recycled deinked old newsprint paper, by linseed oil, enhances the breaking length of paper and remarkably improves its electrical properties i.e., the dielectric constant increases greatly and the a.c. conductivity decreases significantly due to impregnation. It was found that the electrical properties of deinked recycled old newsprint paper and its linseed oil impregnated counterpart, are close to the electrical properties of paper made from the more expensive virgin wood pulps and their linseed oil impregnated counterparts. In a series of research articles, the authors and others threw light for the first time on the electrical properties of paper made from agricultural residues pulps, and their linseed oil impregnated counterparts. Some, of the investigated agricultural residues papers, showed electrical properties close to wood papers, or even superior to it. This motivated the authors to expand the studies, on electrical properties of paper, to other cheap and abundant raw materials. Recycled old newsprint is an abundant raw material that is cheaper than virgin wood pulps. Therefore, recycled deinked old newsprint paper was chosen as a new raw material to study its electrical properties in this work. The effect of elevated temperatures on the electrical properties of paper is, also, studied. It is shown that improvement in electrical properties, due to impregnation, is sustained at elevated temperatures. Impregnated deinked recycled old newsprint paper produced in this work finds its use as specialty electrical purposes paper.

description: Self-bonding of air-dried undebarked cotton stalks during hot pressing in a closely fitting mold was studied. Advanced board-like green nanocomposites from ground undebarked cotton stalks were introduced for the first time in the present work. The dry forming process was adopted. Moderate molding pressure and temperature were selected and applied in a tight die, thus saving water and energy and avoiding the use of any binders to achieve an environment-friendly green product. Green nanocomposites having densities in the range of 1.27–1.29 g/cm3 and 1.03–1.06 g/cm3 were prepared. Particle size and cell wall morphological structure were found to play a major role in self-bonding. Properties of composites prepared from the fine fraction of cotton stalks were superior to those prepared from the cotton stalk coarse fraction at the same conditions. This is attributed—among other things—to the dominance of pith (parenchymal cells) in the fine fraction. Such cells possess a high lumen-to-cell wall ratio, which renders them more deformable under pressure, leading to more intercellular or interparticle bonding. Advanced binderless green nanocomposites having bending strength as high as 637 kg/cm2 and water absorption as low as 12.1 % were obtained from the ground undebarked cotton stalks. The results show clearly that the advanced green nanocomposite obtained by the dry forming process, without the addition of any binders, is superior to hardboard obtained from cotton stalks by the conventional wet web formation process. The mechanism of self-bonding is discussed.

description: This proposal is to assess how to make SB 1138 a success in California as it relates to provision of plant-based diets in licensed health care facilities.  It does not address prisons, which are also covered by SB 1138, or schools, where there are similar advocacy efforts and initiatives in process by groups such as Lean and Green Kids. However, this GAP project will be replicable in those areas.  It is not intended to be a statistical study, although it may identify a need for statistical studies on certain aspects of implementation of SB 1138. For example, the limited baseline of menus could be used to do a statistical analysis of the effectiveness of SB 1138 after it has been in effect for a period of time. Also, analytics of the increased use of plant-based meals will establish efficacy.

description: The present work introduces mild – room temperature – potassium permanganate treatment of cellulosic materials, namely already bleached pulps. Such treatment represents a new approach for upgrading pulp and paper quality, which is lacking in the literature. Potassium permanganate was investigated as a purifying and mild oxidizing agent for commercial already bleached softwood and bagasse pulps. It was found that treatment of the bleached beaten pulps, with 0.25–2% KMnO4 (based on pulp weight), led to significant improvement in paper properties. The strength (breaking length) increased greatly and the brightness increased significantly due to treatment. The improvements were related to the degree of polymerization, and to the alphacellulose content of pulps. Moreover, potassium permanganate serves as a disinfectant and deodorizer. Thus treatment of bleached pulps with KMnO4 is a promising remedy for the side effects which pulps suffer, during transportation and storage, before papermaking.

description: Two simple organic compounds, 5-nitroisophthalic acid (npa) and 4,4′-bipyridine (bpy), were used as building blocks for supramolecular self-assembly by hydrothermal synthesis. SEM, TEM, and XRD were used to analyse the multi-step assembly process in which npa and bpy assembled into nanotubes (or nanobelts) of about 30–100 nm in diameter and several millimetres in length and microtubes (or microbelts). The tubes then further assembled to form complex ordered structures, such as pom-pom-shaped and flower-like mesostructures. Hydrothermal-promoted, self-assembly of 5-nitroisophthalic acid and 4,4′-bipyridine generates nanotubes possessing a diameter of ~30–100 nm diameter and length of several millimeters as well as novel pom-pom- and flower-shaped mesostructures.

description: A combination of azo and acylamide ligands is used in the preparation of metal–organic frameworks. Light response research reveals that under UV–vis irradiation, the CO2 adsorption of 1 declines as much as 21.4%. 1 exhibits excellent CO2 adsorption selectivity over CH4, O2, CO, and N2 gasses with IAST selectivity of 21–580 at 293 K. This MOF also has promising potential in separation of xylene isomers in the liquid phase with the adsorption of p-xylene of 265.15, o-xylene of 101.25 and m-xylene of 0 mg g−1, respectively.

description: We reconstruct the unknown shape of a flow domain using partially available internal velocity measurements. This inverse problem is motivated by applications in cardiovascular imaging where motion-sensitive protocols, such as phase-contrast MRI, can be used to recover three-dimensional velocity fields inside blood vessels. In this context, the information about the domain shape serves to quantify the severity of pathological conditions, such as vessel obstructions. We consider a flow modeled by a linear Brinkman problem with a fictitious resistance accounting for the presence of additional boundaries. To reconstruct these boundaries, we employ a multi-step gradient-based variational method to compute a resistance that minimizes the difference between the computed flow velocity and the available data. Afterward, we apply different post-processing steps to reconstruct the shape of the internal boundaries. To limit the overall computational cost, we use a stabilized equal-order finite element method. We prove the stability and the well-posedness of the considered optimization problem. We validate our method on three-dimensional examples based on synthetic velocity data and using realistic geometries obtained from cardiovascular imaging.

description: This work introduces, for the first time worldwide, undeinked recycled old newsprint as a new resource of electrical purposes paper. Impregnation of undeinked recycled old newsprint paper with linseed oil enhances the breaking length of paper and remarkably improves its electrical properties, i.e., the dielectric constant increases greatly and the a.c. conductivity decreases significantly due to impregnation. It was found that the electrical properties of the undeinked old newsprint paper and its linseed oil impregnated counterpart are close to the electrical properties of paper made from the more expensive virgin wood pulps and their linseed oil impregnated counterparts. Using the undeinked pulp is more privileged than using the deinked pulp; because eliminating the deinking step saves money, time, and reagents. In addition, eliminating the deinking step improved the breaking length of paper. Electron dispersive X-ray elemental analysis (EDX) was used to investigate the undeinked and deinked pulps for residual elements originating from the printing materials. EDX was correlated to the slight differences in electrical properties of paper made from undeinked and deinked pulps. However, impregnation was able to overcome these slight differences. It was shown that improvement in electrical properties, due to impregnation, is sustained at elevated temperatures.

description: In normal thyroid glands, adipose tissue is distributed only under the capsule and along vessels.It is not usually present within the thyroid gland. Only a few adipose tissue -containing thyroid lesions have been reported to date. Lipomatosis of thyroid gland is very rare condition,characterized by infiltration of adipose tissue in the thyroid gland.The pathophysiology of adipose tissue infiltration in the thyroid gland remains unclear. We report a case of a 69-year-old female who presented in the Emergency Room of our hospital, complaining dysphaghia,dyspnea ,swelling of the neck and weight loss. Her thyroid panel tests were in the range,ultrasound showed the typical appearance of multinodular goiter.A computed tomography revealed a rightward tracheal deviation and compression narrowing the tracheal lumen more than 50%. The patient underwent total thyroidectomy. The histopathological examination revealed that adipose tissue was diffusely distributed throughout the thyroid gland.There is no evidence of atypia or mitotic activity. Capsular infiltration or amyloid deposition were not observed. Nuclear grooves or intranuclear cytoplasmic inclusions were not observed. Accordingly, diffuse lipomatosis of thyroid gland was diagnosed.

description: This work introduces, for the first time worldwide, the means to preserve and protect the natural nanoporous structure of the never-dried plant cell wall, against the irreversible collapse, which occurs due to drying. Simultaneously, these means, used for the above-mentioned aim, provide a gateway to novel nanocomposite materials, which retain the super reactive and super absorbent properties of the never-dried biological cellulose fibers. The present work showed, for the first time worldwide, that glucose can be vaccinated into the cell wall micropores or nanostructure of the never-dried biological cellulose fibers, by simple new techniques, to create a reactive novel nanocomposite material possessing surprising super absorbent properties. Inoculation of the never dried biological cellulose fibers, with glucose, prevented the collapse of the cell wall nanostructure, which normally occurs due to drying. The nanocomposite, produced after drying of the glucose inoculated biological cellulose, retained the super absorbent properties of the never dried biological cellulose fibers. It was found that glucose under certain circumstances grafts to the never dried biological cellulose fibers to form a novel natural nanocomposite material. About 3-8% (w/w) glucose remained grafted in the novel nanocomposite.

description: Surfactin, a natural lipopeptide produced by Bacillus, is gaining attention for potentially biomedical and pharmaceutical applications. Here, surfactin was assayed for oral delivery of insulin (INS) by its ability to bind to and promote protein to penetrate through the cell membrane. Analysis by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, surfactin was found to form co-precipitates with INS to protect it from acidic and enzymatic attack in the gastrointestinal tract. Further analysis by non-reductive electrophoresis showed surfactin could bind to INS forming heteropolymers. Analysis with circular dichroism, we found this binding significantly influenced the INS structure with decreased rigid α-helix and β-turn, but with increased flexible β-sheet and random coil. The change with more flexible structure was favorable for INS to penetrate through the cell membrane. Fluorescence spectra analysis also showed surfactin could lead Phe and Tyr in the inner of INS exposed outside, further promoting INS permeabilization by improving the hydrophobic-lipophilic interactions between INS and cell membrane. As a result, the effective permeability (Peff) of INS plus surfactin was 4.3 times of that of INS alone. In vivo assay showed oral INS with surfactin displayed excellent hypoglycemic effects with a relative bioavailability of 12.48% and 5.97% in diabetic mice and non-diabetic dogs, respectively. Summary, surfactin is potential for oral delivery of INS by its role as an effective protease inhibitor and permeability enhancer.

description: Objectives: Studies examining whether glutathione S-transferase M1 (GSTM1) polymorphisms are associated with Parkinson’s disease (PD) have reported inconsistent results. To clarify those inconsistencies, a meta-analysis was performed. Methods: The electronic databases were searched for all publications regarding the association. Studies were included if they met the eligibility criteria. The strength of the association between GSTM1 polymorphisms and PD risk was measured by odds ratios (ORs) and 95% confidence intervals (CIs) in the recessive genetic model (null genotype vs. present genotype). Subgroup analyses by ethnicity and OR type were performed. Results: A total of 22 publications (23 studies) were included. There were 14, 7 and 2 studies with Caucasians, Asians and Latinos, respectively. OR types were 15 and 8 studies with crude and adjusted ORs, respectively. The combined results of the overall analysis showed that the GSTM1 null genotype was not significantly associated with PD risk (ORrandom-effects = 1.06, 95% CI = 0.95–1.19). In subgroup analyses by ethnicity, no significant associations were found in Caucasians, Asians or Latinos individually. Similarly, there were no associations in the subgroup analyses by OR type. There were no obvious publication biases in any of the comparisons. Discussion: The results of this meta-analysis suggest that the GSTM1 null genotype is not significantly associated with PD risk.

description: This study introduced, for the first time worldwide, molasses as an additive in papermaking. The introduction of molasses as an additive in papermaking resulted in paper composites with greater breaking length and remarkably higher water retention value (WRV), compared with paper that does not have molasses as an additive. Previous studies have shown that incorporating the cell wall microstructure of cellulose fibers with sucrose greatly enhanced the breaking length and WRV. It is well established in the literature that using gums (including starch) as additives in papermaking enhances paper strength. Molasses, which contains sucrose and gums (including starch) is a byproduct of the sugar industry and is cheaper than sucrose. Mercerization of pulp fibers before loading them with molasses was shown to greatly enhance the positive effects produced by loading with molasses. Application: Paper composites produced using molasses as an additive are useful as specialty absorbent paper.
