Safety Tracking is the process of tracing a person’s ware bouts and their vitals and health in case of an emergency or accident. A device which sends or saves this data is considered as a safety tracking device. This device may help multiple sensors attached to the device itself or attached to the person there by reading and sending their ware boats and data within the parameter of the workspace in a company to a live supervisor or data storage so that it can be reviewed in case an accident occurs. This data can be used to study any accidents involving that person and device preventive measures of that accident again. The novel system can acquire the real-time working condition information of faculties such as pipe flow, pressure, temperature, humidity of the environment, current & voltage of the electrical equipment, valve switch, relay action, alarming message it can upload the collected data to the monitoring center to the client/server architecture. Based on these data, an electrical early warning model depending on the change in surroundings based on neural work is proposed. A personal safety evaluation model based on ontology with the usage of protege is established, which facilitate the on-line monitoring and control of building fire protection information, the prediction of accidents and improve building safety level evaluation.

Authors: Rajendran Poornima , Namburi Rajesh
Published: August 2023

Background: Both the practitioner and the patient frequently deal with gingival recession. In Miller’s Classes I and II mandibular gingival recession, the goal of this study was to evaluate the predictability of the free gingival graft (FGG), as a single-step operation in terms of root coverage and esthetics. Materials and Methods: 10 patients between the ages of 25 and 50 who were sent to the Department of Periodontics (3 men and 7 women) made up the study group. There were a total of 14 mandibular recession sites that were chosen. Recession depth (RD), recession width, probing depth (PD), clinical attachment level (CAL), width of attached gingiva (WAG), and visual analog scale (VAS) were assessed at baseline, 3 months, and 6 months post-operatively. Results: The mean RD was 3.13±2.0 mm at the baseline and decreased to 0.80±0.78 mm after 6 months. At baseline, the VAS was 3.52±0.81, and at 6 months after surgery, it had improved to a mean of 6±2.14. From a baseline WAG of 0.35±0.38 to 2.83±0.68 mm, there wasa significant increase with p<0.0001. Six months after surgery, there was an increase in CAL, from 5.63±1.12 to 1.28±0.76 mm. In addition, PD improved from 1.98±0.54 to 0.97±0.36 mm. Conclusion: FGG showed statistically significant gain in recession coverage and had good esthetic score. The technique produced a reliable single-step gain in WAG as well as root coverage in cases of Miller’s Classes I and II gingival recession.
Methods for detection of biofilms in bacteria and fungi
Authors: Bhattacharya Sayan
Published: August 2023

Biofilms are layer-like structures formed by microorganisms and extracellular matrix produced by them on indwelling devices. Biofilms can also readily form over catheters and devices like prosthetic valves. They help in conferring drug resistance to the biofilm-associated cells and help the microbes escape from antimicrobials as well as the immune defense of the host. There are also many methods of detecting microbial biofilms in vitro, which will be reviewed in this article.

Authors: Ghadge Tejal , Deshpande Snehal
Published: August 2023

Self-gratification behavior is a normal behavior in infants or children and is usually misdiagnosed with dystonic development delays, repeated movement disorders, or even epilepsy. This case report aims to share our clinical experience in managing a child with self-gratification disorder through physical therapy techniques. An 8-month-old female infant presents with concerns related to poor social interaction, reduced play, irritable behavior, frequent crossing, and stiffness in the legs which she started showing at 3 months of age. She was earlier diagnosed with dystonic developmental delay and referred for a thorough development and sensory assessment. Rehabilitation with sensory integration and neurodevelopmental techniques was delivered to the child. Ages and Stages Questionnaire, Denver’s score, and Sensory profile were assessed at 8–9 months, 9–10 months, and 10–11 months to monitor prognosis. There was a significant improvement in self-gratification habits and improved attention in the child. Self-gratification behavior is a normal behavior in infants or children and is usually misdiagnosed. Treatment mainly constitutes neurodevelopment, sensory integration techniques, and parent education.

Authors: IYER SHRUTI
Published: August 2023

Non-Hodgkin’s lymphoma is a heterogeneous group of malignancies characterized by an abnormal clonal proliferation of T-cells, B-cells, or both. Sometimes, tuberculosis and lymphoma presentation can share common symptoms and features. In this case report, we present the case of a 28-year-old female patient who came with a chief complaint of swelling on the right side of the face for the past 6 months. Initially, it was not associated with pain but gradually developed severe pain over the region and reduced salivary flow. The patient was planned for surgery with a differential diagnosis of salivary gland pathology. Post-operatively, the histopathological report showed atypical cells which were diffusely positive for cluster of differentiation (CD)20. Focally positive for CD45 and CD3 which was positive in reactive T lymphocytes. Immunohistochemistry pattern favors the diagnosis of B-cell type NHL. Through this case report, we want to share our experience in treating an aggressive tumor that mimics salivary gland pathology.

Authors: Peng He , Jiang Xianquan , Bai Xuefei , LI Dongyang , Chen Daolun
Published: August 2023

Lightweight structural applications of magnesium and aluminum alloys inevitably necessitate welding and joining, especially dissimilar welding between these alloys. The objective of this study was to examine the feasibility of joining ZEK100 Mg alloy to Al6022 alloy via ultrasonic spot welding, focusing on effects of welding energy. An interface diffusion layer consisting of α-Mg and Al12Mg17 eutectic structure was observed to form, with its thickness increased from ~0.5 µm to ~30 µm with increasing welding energy from 500 J to 2000 J. The tensile lap shear peak load or strength and critical stress intensity of the welded joints first increased and then decreased with increasing welding energy, with their peak values achieved at 750 J. Fatigue life of the joints made at 750 J and 2000 J was equivalent at the lower cyclic loading levels, while it was longer for the joints made at 750 J at the higher cyclic loading levels. Fatigue fracture mode changed from interfacial failure to mainly transverse-through-thickness crack growth with decreasing cyclic loading level, which corresponded well to the bi-linear characteristic of S-N curves. Crack initiation basically occurred at the weld nugget border and at the interface between the two sheets, which can be understood via a theoretical stress analysis.

Published: August 2023

The stretch formability behavior of an AZ61 magnesium alloy plate produced by multi-pass friction stir processing (M-FSP) was investigated, with the applied load vs. displacement curves recorded during Erichsen cupping tests at different punching speeds at room temperature. The stretch formability of M-FSP AZ61 magnesium alloy was significantly enhanced, compared with that of its cast counterpart. The highest Erichsen index of 3.7 mm was obtained at a punching speed of 0.1 mm/min. The improved stretch formability was mainly attributed to the grain refinement stemming from the M-FSP and the presence of extension twinning to accommodate deformation during Erichsen cupping testing.

Published: August 2023

The aim of this study was to identify and analyze the fatigue fracture characteristics of dissimilar Al 6061 to Cu (UNS C11000) lap joints made with ultrafast electromagnetic pulse welding (EMPW) via fractography, stress analysis and finite element simulation. It was observed that EMPW generated an annular (or ring-shaped) bonding area, with weld zones and a central non-weld zone when viewed from the cross section. Two types of failure modes occurred in relation to the cyclic loading levels: base metal fracture or transverse through-thickness (TTT) crack growth at a higher loading level, and joint interfacial failure at a lower loading level. In the interfacial failure, fatigue crack initiated from the outer edge of annular welding area, and propagated to form an approximate elliptical boundary. Fatigue crack propagation was characterized by fatigue striations existing in discrete areas on the fracture surface. This was attributed to a coupled role of shear and normal stresses present in a tensile lap shear sample due to the bending moment caused by the inherent misalignment. The final rapid fracture started from elliptical boundary with elongated shear dimples. Both theoretical stress analysis and finite element model revealed the maximum stress and stress concentration along the outer edge, where fatigue crack initiation occurred.

Published: August 2023

The aim of this study was to characterize detailed microstructural changes and bonding characteristics and identify the formation mechanism of collision surface of Al6061–Q355 steel dissimilar welded joints via electromagnetic pulse welding (EMPW). The collision surface was observed to consist of five zones from the center to the outside. The central non-weld zone exhibited a concave and convex morphology. The welding-affected zone mainly included melting features and porous structures, representing a porous joining. The secondary weld zone presented an obvious mechanical joining characterized by shear plateaus with stripes. The primary weld zone characterized by dimples with cavity features suggested the formation of diffusion or metallurgical bonding. The impact-affected zone denoted an invalid interfacial bonding due to discontinuous spot impact. During EMPW, the impact energy and pressure affected the changes of normal velocity and tangential velocity, and in turn, influenced the interfacial deformation behavior and bonding characteristics, including the formation of micropores which continued to grow into homogeneous or uneven porous structures via cavitation, surface tension, and depressurization, along with the effect of trapped air.

Published: August 2023

Designing and developing the Mg alloys with low cost and high performance is of the great significance. Novel Mg-1Bi-xMn (x = 0, 1 and 2 wt.%) extruded alloys, in this work, were fabricated at different extrusion temperatures (220, 250 and 300 °C). The effects of extrusion temperature and Mn addition on the microstructures and mechanical properties of extruded alloys at room temperature were investigated. The results showed that decreasing the extrusion temperature could refine the average grain size, weaken the basal fiber texture intensity and improve the microstructural homogeneity of extruded alloys. When the Mn element was added to the Mg-1Bi alloy, the average grain size further reduced. Simultaneously, the number fraction of low angle grain boundaries (LAGBs) increased, along with the occurrence of regions without dynamic recrystallization (unDRX). The combined effects of grain refinement and coarse unDRXed structure made the textures of the extruded Mg-1Bi-xMn alloys never obviously change. Besides few large size un-dissolved second phases, fine Mg3Bi2 and α-Mn phases were precipitated in the extruded Mg-1Bi-xMn alloys and partial nano-scale α-Mn particles pined at grain boundaries (GBs) to effectively impede the migration of GBs for grain refinement. Microstructural variations determined the extruded Mg-1Bi-2Mn alloy to exhibit the highest yield strength of ∼ 319.2 MPa with the appropriate elongation-to-failure of ∼ 13% at the extrusion temperature of 220 °C, and they enabled the extruded Mg-1Bi-1Mn alloy to show the highest elongation-to-failure of ∼ 26% without the obvious loss of yield strength of ∼ 252.1 MPa.
Prediction of probable backorder scenarios in the supply chain using Distributed Random Forest and Gradient Boosting Machine learning techniques
Authors: Islam Samiul , Hassanzadeh Amin Saman
Published: August 2023

Prediction using machine learning algorithms is not well adapted in many parts of the business decision processes due to the lack of clarity and flexibility. The erroneous data as inputs in the prediction process may produce inaccurate predictions. We aim to use machine learning models in the area of the business decision process by predicting products’ backorder while providing flexibility to the decision authority, better clarity of the process, and maintaining higher accuracy. A ranged method is used for specifying different levels of predicting features to cope with the diverse characteristics of real-time data which may happen by machine or human errors. The range is tunable that gives flexibility to the decision managers. The tree-based machine learning is chosen for better explainability of the model. The backorders of products are predicted in this study using Distributed Random Forest (DRF) and Gradient Boosting Machine (GBM). We have observed that the performances of the machine learning models have been improved by 20% using this ranged approach when the dataset is highly biased with random error. We have utilized a five-level metric to indicate the inventory level, sales level, forecasted sales level, and a four-level metric for the lead time. A decision tree from one of the constructed models is analyzed to understand the effects of the ranged approach. As a part of this analysis, we list major probable backorder scenarios to facilitate business decisions. We show how this model can be used to predict the probable backorder products before actual sales take place. The mentioned methods in this research can be utilized in other supply chain cases to forecast backorders.

Published: August 2023

Practically no studies on drip irrigation of raspberries in the conditions of the Moscow region have been carried out, in particular, the patterns of the production process of plants under drip irrigation have not been identified. In this regard, the purpose of the research was to study the effect of drip irrigation regimes on the formation of raspberry seedlings in the conditions of soddy-podzolic soils in the Central region of the Non-Chernozem zone of Russia. The studies were carried out on the lands of the educational and experimental farm of the laboratory of fruit growing "Michurinskiy Sad" of the Russian State Agrarian University - Moscow Timiryazev Agricultural Academy in 2020-2022. The two-factor field experience included regimes as the first factor, and varietal characteristics as the second. As a result of the research, it was revealed that drip irrigation contributes to the saving of irrigation water and the creation of an optimal water-air regime of the soil during the entire growing season. In the variant of drip irrigation with maintaining moisture in the root layer in the range of 80-100% of the lowest moisture capacity, the saving of irrigation water compared to furrow irrigation averaged 65%, and in the variant of 60-80% of the lowest moisture capacity - 78%. Drip irrigation contributes to the formation of seedlings with the highest values of biometric indicators (stem diameter, plant height, leaf surface area and volume, length, mass of the root system) and increase productivity. An analysis of the experimental data on the biometric indicators of raspberries and its yield allows us to recommend irrigation regimes with maintaining the moisture content of the root layer of the soil in the range of 70-90% of the lowest moisture capacity and 80-100% of the lowest moisture capacity as optimal.
A Study on English Equivalents of Cantonese Sentence-Final Particles: Zaa3 and Ze1 as an Example
Authors: Zhang Xiaoshuai
Published: August 2023

This study explores English equivalents of the Cantonese sentence-final particles (SFPs) zaa3 and ze1 by utilizing Natural Semantic Metalanguage (NSM) explications to analyze their semantic components and roles and conducting a phonetic experiment to find the English intonational equivalents. While zaa3 and ze1 both convey the meaning of “only” or “just” in Cantonese, this research reveals that they differ in connotations, are contextually specific, and their implied meanings cannot be adequately captured through direct translation into English. To address this, the study employs NSM explications as the analytical framework and a phonetic experiment involving research participants of two Cantonese native speakers and one English native speaker is conducted to identify the English intonational equivalents of these Cantonese SFPs. The study aims to answer two research questions: (i) What are the NSM explications of the Cantonese sentence-final particles zaa3 and ze1? (ii) Do either of the two Cantonese SFPs possess English intonational equivalents, and if so, what are they? Zaa3 often conveys a sense of complaint or dissatisfaction, suggesting insufficient quantity, while ze1 typically conveys modesty or humility, implying an unremarkable or ordinary quantity. An NSM explication for zaa3 involves the Cantonese semantic primes M4 DO1, SEONG2 DO1 DI1, which translate to “NOT MORE, WANT MORE” in English equivalents. On the other hand, an NSM explication for ze1 comprises M4 DO1, M4 SEONG2 JAN4 GOK3 DAK1 DO1 in Cantonese semantic primes, corresponding to “NOT MORE, DON’T WANT SOMEONE FEEL MUCH~MANY” in English equivalents. These nuanced implied meanings cannot be effectively conveyed through direct translation alone, requiring consideration of intonation patterns in English. The phonetic experiment conducted using Praat software clearly demonstrates distinct pitch contours when participants read English sentences translated from Cantonese sentences containing zaa3 and ze1, respectively. The findings indicate that the English equivalents of the Cantonese SFP zaa3 encompass the meanings of “only” or “just”, accompanied by a falling pitch contour when speakers read the corresponding English translation. Conversely, the English equivalents of the Cantonese SFP ze1 entail the meanings of “only” or “just”, along with the highest pitch point occurring at the end of the sentence in the English translation. In conclusion, this research sheds light on the English equivalents of the Cantonese SFPs zaa3 and ze1, highlighting their divergent connotations and nuanced implied meanings. The study emphasizes the importance of considering intonation patterns to accurately convey these nuances in English translations.

Authors: Kharbanda Prem Raj
Published: August 2023

Genres are integral to and critically important for any ESP writing course. As part of the needs analysis to design an ESP writing course, classroom teaching frequency and professional usefulness of writing genres for engineering students were matched and correlated. The four groups comprising students, teachers, operational and managerial engineers were compared in terms of their responses to the teaching and usefulness of genres. Accordingly, post hoc analysis was carried out, and means were compared wherever the differences were found to be significant. It has been established through this research that needs analysis of all the important stakeholders- students, professional engineers, teachers – should be done because there are gaps in their respective perceptions regarding the use of genres in an ESP course and through such a triangulated assessment, the gaps can be minimized.

The article deals with the role of semantic research for the creation of intelligent systems for automated processing of language information. An approach to the development of linguistic and informational tools for automated extraction of semantic and cognitive information from the text is outlined. The issue of increasing the efficiency of high-quality and fast processing of digital information, the creation of highly intelligent, fast-acting information systems was raised. The theoretical basis of the research is the lexicographic theory of symbolic semantic systems developed by academician V. A. Shyrokov and the theory of semantic states of natural language units built within it, which is based on the principles of lexical semantics and is oriented towards the use of computer technologies in semantic research. An integrated lexicographic system created in the Ukrainian Language and Information Fund of the National Academy of Sciences of Ukraine was selected as the source base of the study, the core component of which is the computer version of the «Dictionary of the Ukrainian Language» in 20 volumes, which is the most representative source of semantic information that provides a description of the lexical meaning of a word according to many parameters with the involvement of pragmatic, connotative, syntagmatic and linguistic contexts. In the study, the formalism of the theory of semantic states is used to build a linguistic and informational toolkit for automatic recognition of semantic and cognitive information in texts written in natural languages. The proposed semantic classifier provides an explicit presentation of the information extracted from the text, which enables its further software processing thanks to the unified interpretation of the operators of the semantic state formula and the results of the semantic indexing of the text. The expediency of using the developed language and information toolkit for solving such important tasks of computer linguistics as determining formal criteria for distinguishing lexical homonyms and LSV of a polysemous word, correct establishment of structural contrasts «meaning — shades», «lexeme — lexical-semantic variants» in interpreting the meaning of the latter, the task of unifying the description of the lexical meaning of words of one semantic field.

Published: August 2023

Wood ash is a residue from the artisanal brick burning process that is produced in the poorest areas of Peru. It is a major problem because there is no management of this type of solid waste and it contaminates large sectors of the population. In this sense, it is important to use sustainable natural elements such as wood ashes that can contribute to the performance of concrete. For this reason, the objective of this research was to evaluate the influence of the incorporation of wood ash on the mechanical properties of concrete, with incorporations of 8%, 12% and 16%, as a function of the weight of cement, for which cylindrical specimens and beams were prepared. The results with respect to slump and unit weight were considerably reduced below their standard samples, unlike the temperature, which had increases that ranged between 3°C. On the other hand, the combined mixture of 8% wood ash resulted in the highest compressive strength, reaching 308,73 kg/cm2 which represents an increase of 9,04% with respect to the standard sample, while the flexural strength was 45,32 kg/cm2 representing an increase of 5,96% with reference to the standard sample. It is concluded that the addition of wood ash significantly improves the mechanical properties of concrete with an optimum dosage of 8%, the result contributes to make it technically feasible as an addition in the elaboration of sustainable concrete in civil construction.

Published: August 2023

The use of multicellular Glass Fiber Reinforced Polymer (GFRP) deck panels in the rehabilitation and construction of bridges has increased over the last 30 years due to several benefits, such as: low maintenance cost, fast installation, corrosion resistance, and high strength-to-weight ratio. Due to the orthotropic nature of GFRP decks and their complex cross-section geometry, expensive computational problems may be obtained when bridges that include these elements are analyzed under traffic loads. Therefore, this paper studies the dynamic response of a GFRP-steel road bridge modelling the multicellular GFRP deck as an orthotropic plate. For this purpose, a finite element model of the hybrid structure is developed, and a sensitivity analysis is carried out to investigate the influence of the mechanical properties of the orthotropic element on the bridge behavior. The roughness of the pavement, the degree of composite action between the deck and the stringers, the multibody dynamic model of a truck, and the vehicle-bridge interaction phenomenon are included in the analyses. Results indicate that the most relevant properties of the orthotropic plate on the response of the structure are the modulus of elasticity in the longitudinal direction, the modulus of elasticity in the transverse direction, and the shear modulus. Also, achieving a full composite action and avoiding deterioration of road are identified as key aspects to reduce the vibration levels on the hybrid bridge.

Published: August 2023

A reiterada lembrança da mídia acerca do ato delituoso cometido por egresso do sistema prisional evidencia a tensão estabelecida entre o direito à liberdade de expressão, o papel da imprensa e a proteção da privacidade e da dignidade da pessoa humana. Neste contexto, o presente artigo tem o objetivo de refletir sobre o direito ao esquecimento no processo penal. Desde a perspectiva da metodologia científica, classifica-se o trabalho como um ensaio de cunho qualitativo e exploratório com abordagem indutiva. O referencial teórico se articula em torno de temas como crimes de repercussão midiática, ressocialização de egressos do sistema prisional e concretização do direito ao esquecimento. A reflexão conclui que a lacuna verificada no âmbito penal representa um desafio à reinserção social de indivíduos condenados por crimes que no passado geraram comoção popular, uma vez que a sua imagem pode ficar permanentemente associada a tais delitos.

ABSTRACT
The repeated remembrance by the media of the criminal act committed by an inmate of the prison system highlights the tension established between the right to freedom of expression, the role of the press and the protection of privacy and human dignity. In this context, this article aims to reflect on the right to forgetfulness in criminal proceedings. From the perspective of scientific methodology, the paper is classified as a qualitative and exploratory essay with an inductive approach. The theoretical framework is articulated around themes such as crimes with media repercussion, resocialization of former inmates of the prison system, and the realization of the right to be forgotten. The reflection concludes that the gap in the criminal justice system represents a challenge to the social reintegration of individuals convicted of crimes that in the past generated a popular commotion, since their image may become permanently associated with such crimes.
Keywords: Right to forgetfulness. Resocialization of former inmates of the prison system. Crimes with media repercussion. Right to freedom of expression. Right to information.

Nyeri paska operasi didefinisikan sebagai nyeri yang dialami setelah intervensi bedah. Jika nyeri tidak dikendalikan, hal tersebut memperpanjang proses penyembuhan dengan menyebabkan komplikasi pernafasan, ekskresi, peredaran darah, dan sistemik lainnya. Sebagai akibatnya, beberapa pasien meninggal, kualitas hidup dan kepuasan pasien menurun, lamanya tinggal di rumah sakit meningkat dan biaya perawatan juga meningkat. Tujuan penelitian ini untuk mengetahui pengaruh mobilisasi dini pada ibu postpartum dengan sectio caesarea terhadap penurunan intensitas nyeri luka operasi di RSIA Nuraida Bogor. Penelitian ini merupakan jenis penelitian pre-eksperimental dengan pendekatan one group pretest – posttest design. Teknik pengambilan sampel dengan menggunakan total sampling. Responden penelitian ini 20 orang ibu postpartum dengan sectio caesarea. Intensitas nyeri diukur dengan menggunakan pengukuran skala nyeri Numeric Rating Scale (NRS). Analisis data menggunakan uji statistic Wilcoxon. Intervensi mobilisasi dini dilakukan mulai dari menekuk kaki, miring ke kanan dan ke kiri, duduk dan kemudian belajar jalan. Mobilisasi dini mulai dilakukan pada 6 jam post operasi. Mobilisasi dibantu oleh petugas kesehatan Hasil uji Wilcoxon menunjukkan nilai p value pada 6 jam, 10 jam, dan 24 jam post operasi adalah 0,000 < α (0,05) yang artinya ada pengaruh mobilisasi dini terhadap penurunan intensitas nyeri luka operasi. Mobilisasi dini berpengaruh terhadap penurunan intensitas nyeri luka operasi
Making Peace with the Devil: The Problem of Ending Just Wars
Authors: Forster Elisabeth , Taylor Isaac
Published: August 2023

In this paper, we draw attention to an unintended but severe side effect of just war thinking: the fact that it can impose barriers to making peace. Investigating historical material concerning a series of conflicts in China during the early twentieth century, we suggest that operating in a just war framework might change actors' identities and interests in a way that makes peacemaking an unavailable action. But since just war theory places significant normative constraints on how long wars can be continued, it might thus be self-defeating, in the sense that those who adopt it may undermine the very goals which it is supposed to serve. Whether this finding calls for a revision of existing ethical frameworks governing warfare will depend on whether there are possible alternatives to just war theory that perform better at reining in unjust violence.
Left Libertarianism for the Twenty-First Century
Authors: Reiff Mark R.
Published: August 2023

There are many different kinds of libertarianism. The first is right libertarianism, which received its most powerful expression in Robert Nozick’s Anarchy, State and Utopia (1974), a book that still sets the baseline for discussions of libertarianism today. The second, I will call faux libertarianism. For reasons I will explain in this paper, most ‘man-on-the-street’ libertarians and most politicians who claim to be libertarians are actually this kind of libertarian. And third, there is left libertarianism, which is what I shall spend most of this paper explicating. But I will not simply be surveying the views of those who identify as left libertarians and put this forth as if I were engaged in an exegetical exercise. Instead, what I shall set forth is a kind of manifesto, a statement of why I consider myself a left libertarian, one that takes this approach to political morality well beyond where it was left around the end of the last century by the previous generation of left libertarians. My hope is to provide those who find certain left libertarian ideas attractive a guide by which they can explain and harmonise their own views, recognise left libertarianism as a distinct comprehensive political doctrine, and feel more open to identify themselves as left libertarian too.
Optimisation of recombinant TNFα production in Escherichia coli using GFP fusions and flow cytometry

Escherichia coli is commonly used industrially to manufacture recombinant proteins for biopharmaceutical applications, as well as in academic and industrial settings for R&D purposes. Optimisation of recombinant protein production remains problematic as many proteins are difficult to make, and process conditions must be optimised for each individual protein. An approach to accelerate process development is the use of a green fluorescent protein (GFP) fusions, which can be used to rapidly and simply measure the quantity and folding state of the protein of interest. In this study, we used GFP fusions to optimise production of recombinant human protein tumour necrosis factor (rhTNFα) using a T7 expression system. Flow cytometry was used to measure fluorescence and cell viability on a single cell level to determine culture heterogeneity. Fluorescence measurements were found to be comparable to data generated by subcellular fractionation and SDS-PAGE, a far more time-intensive technique. We compared production of rhTNFα-GFP with that of GFP alone to determine the impact of rhTNFα on expression levels. Optimised shakeflask conditions were then transferred to fed-batch high cell density bioreactor cultures. Finally, the expression of GFP from a paraBAD expression vector was compared to the T7 system. We highlight the utility of GFP fusions and flow cytometry for rapid process development.

Regeneration of bone defects is often limited due to compromised bone tissue physiology. Previous studies suggest that engineered extracellular matrices enhance the regenerative capacity of mesenchymal stromal cells. In this study, we used human-induced pluripotent stem cells, a scalable source of young mesenchymal progenitors (hiPSC-MPs), to generate extracellular matrix (iECM) and test its effects on the osteogenic capacity of human bone-marrow mesenchymal stromal cells (BMSCs). iECM was deposited as a layer on cell culture dishes and into three-dimensional (3D) silk-based spongy scaffolds. After decellularization, iECM maintained inherent structural proteins including collagens, fibronectin and laminin, and contained minimal residual DNA. Young adult and aged BMSCs cultured on the iECM layer in osteogenic medium exhibited a significant increase in proliferation, osteogenic marker expression, and mineralization as compared to tissue culture plastic. With BMSCs from aged donors, matrix mineralization was only detected when cultured on iECM, but not on tissue culture plastic. When cultured in 3D iECM/silk scaffolds, BMSCs exhibited significantly increased osteogenic gene expression levels and bone matrix deposition. iECM layer showed a similar enhancement of aged BMSC proliferation, osteogenic gene expression, and mineralization compared with extracellular matrix layers derived from young adult or aged BMSCs. However, iECM increased osteogenic differentiation and decreased adipocyte formation compared with single protein substrates including collagen and fibronectin. Together, our data suggest that the microenvironment comprised of iECM can enhance the osteogenic activity of BMSCs, providing a bioactive and scalable biomaterial strategy for enhancing bone regeneration in patients with delayed or failed bone healing.
