A critical review on optimization parameters and techniques for gas pipeline operation profitability
Authors: Arya Adarsh Kumar 
Published: April 2022

AbstractPipelines have traditionally been recognized as the most cost-effective and safe mode for transporting natural gas. However, since a tremendous amount of gas is transported through pipelines, a massive investment is required to construct and operate pipeline networks. The oil-and-gas sector has embraced pipeline optimization because of its potential to cut down pipeline costs significantly. However, the inclusion of several variables, single or multiple goals, and intricate linear–nonlinear equality and inequality constraints make pipeline optimization a significant challenge.In recent years, the natural gas industry has experienced a surge in pipeline optimization parameters and techniques to lower the pipeline cost. Numerous researchers have previously focused on developing effective algorithmic modifications to enhance certain search capabilities. However, very few review papers have been published, despite being critical for engineering solution providers. The paper tries to fill this gap by detailing the many gas pipeline optimization parameters, fourteen in our case, tuned to obtain the most outstanding pipeline operating advantages. In addition, the six most widely accepted pipeline optimization techniques, viz. Ant colony, Genetic algorithm, Differential evolution, Particle swarm, Simulated annealing, and Whale optimization algorithms, are also detailed. Furthermore, the potential solution approach for pipeline optimization problems is addressed to supplement the application. The findings of this study intend to enhance the understanding of the methodology, techniques, and advantages of implementing optimization to the pipeline industry, allowing for maximum operational benefits in a period of diminishing fossil fuel supplies.

AbstractPorosity and facies are two main properties of rock which control the reservoir quality and have significant role in petroleum exploration and production. Well and seismic data are the most prevalent information for reservoir characterization. Well information such as logs prepare adequate vertical resolution but leave a large distance between the wells. In comparison, three-dimensional seismic data can prepare more detailed reservoir characterization in the inter-well space. Generally, seismic data are an efficient tool for identification of reservoir structure; however, such data usable in reservoir characterization. Therefore, these two types of information were incorporated in order to obtain reservoir properties including porosity and facies in the study area. Using Multimin algorithm, petrophysical analysis was carried out for estimation of reservoir porosity. Then, an accurate post-stack inversion was accomplished to obtain the acoustic impedance volume. The results showed that the Ghar sandstone is characterized by a lower acoustic impedance compared to the high acoustic impedance Asmari Formation. Because of a relationship between acoustic impedance and reservoir properties (i.e., porosity), porosity cube calculation was performed by artificial neural network method which is a popular approach for parameter estimation in petroleum exploration. The consequences showed a good agreement between log based and seismic inversion-derived porosity. The inversion results and well logs cross-plots analyses illustrated that the Ghar member considered as a high quality zone with porosity 22 to 32 percent and the Asmari dolomite shows a low quality interval characters with porosity 1 to 6 percent. The findings of this study can help for better understanding of reservoir quality (especially porous Ghar member delineation) by lithology discrimination in the analysis of identification reservoirs and finding productive well location in Hendijan field.
Micromechanical Force Measurement of Clotted Blood Particle Cohesion: Understanding Thromboembolic Aggregation Mechanisms
Authors: McKenzie Angus J. , Doyle Barry J. , Aman Zachary M. 
Published: April 2022

Abstract
Purpose
Arterial shear forces may promote the embolization of clotted blood from the surface of thrombi, displacing particles that may occlude vasculature, with increased risk of physiological complications and mortality. Thromboemboli may also collide in vivo to form metastable aggregates that increase vessel occlusion likelihood.

Methods
A micromechanical force (MMF) apparatus was modified for aqueous applications to study clot-liquid interfacial phenomena between clotted porcine blood particles suspended in modified continuous phases. The MMF measurement is based on visual observation of particle-particle separation, where Hooke’s Law is applied to calculate separation force. This technique has previously been deployed to study solid–fluid interfacial phenomena in oil and gas pipelines, providing fundamental insight to cohesive and adhesive properties between solids in multiphase flow systems.

Results
This manuscript introduces distributed inter-particle separation force properties as a function of governing physio-chemical parameters; pre-load (contact) force, contact time, and bulk phase chemical modification. In each experimental campaign, the hysteresis and distributed force properties were analysed, to derive insight as to the governing mechanism of cohesion between particles. Porcine serum, porcine albumin and pharmaceutical agents (alteplase, tranexamic acid and hydrolysed aspirin) reduced the measurement by an order of magnitude from the baseline measurement—the apparatus provides a platform to study how surface-active chemistries impact the solid–fluid interface.

Conclusion
These results provide new insight to potential mechanisms of macroscopic thromboembolic aggregation via particles cohering in the vascular system—data that can be directly applied to computational simulations to predict particle fate, better informing the mechanistic developments of embolic occlusion.

AbstractThe complexity of handheld steerable laparoscopic instruments (SLI) may impair the learning curve compared to conventional instruments when first utilized. This study aimed to provide the current state of interest in the use of SLI, the current use of these in daily practice and the type of training which is conducted before using SLI in the operating room (OR) on real patients. An online survey was distributed by European Association of Endoscopic Surgery (EAES) Executive Office to all active members, between January 4th and February 3rd, 2020. The survey consisted of 14 questions regarding the usage and training of steerable laparoscopic instruments. A total of 83 members responded, coming from 33 different countries. Twenty three percent of the respondents using SLI, were using the instruments routinely and of these 21% had not received any formal training in advance of using the instruments in real patients. Of all responding EAES members, 41% considered the instruments to potentially compromise patient safety due to their complexity, learning curve and the inexperience of the surgeons. The respondents reported the three most important aspects of a possible steerable laparoscopic instruments training curriculum to be: hands-on training, safe tissue handling and suturing practice. Finally, a major part of the respondents consider force/pressure feedback data to be of significant importance for implementation of training and assessment of safe laparoscopic and robotic surgery. Training and assessment of skills regarding safe implementation of steerable laparoscopic instruments is lacking. The respondents stressed the need for specific hands-on training during which feedback and assessment of skills should be guaranteed before operating on real patients.

Published: April 2022

AbstractTo decrease the eutrophication caused by nitrogen (N) and phosphorus (P) in water, magnesium-modified corn stalk biochar (MgB) was prepared under the synergistic impact of the multi-pyrolysis temperatures and Mg2+ contents for the co-adsorption of ammonium (NH4+-N) and phosphate (PO43−). The co-adsorption mechanism, slow-release performance and plant application of MgB were systematically studied. The results showed that pyrolysis temperatures (350–650 °C) and Mg2+(0–3.6 g/L) contents not only altered the physicochemical properties of biochar, but also significantly affected the adsorption efficacy of MgB. The adsorption of NH4+-N and PO43− was in accordance with Langmuir–Freundlich and pseudo-second-order kinetic models (Qmax = 37.72 and 73.29 mg/g, respectively). Based on the characteristics, adsorption kinetics and isotherms results, the adsorption mechanism was determined and found to mainly involve struvite precipitation, ion exchange, and surface precipitation or electrostatic attraction. Compared with the leaching performance of chemical fertilizers (CF), after adsorption of NH4+-N and PO43− (MgB-A), MgB had a more stable pH and lower conductivity. Leaching of NH4+-N and PO43− by MgB-A was controlled by both the diffusion mechanism and the dissolution rate of struvite and Mg-P. The excellent long-term slow-release performance and abundant Mg2+ of MgB-A promoted the growth of Zea mays L. and Lolium perenne L. Overall, this study suggested that MgB could realize a win–win outcome of struvite biochar-based fertiliser production and wastewater treatment.

Published: April 2022

AbstractHeterogeneous photocatalysis is one of the most studied and promising techniques for degradation of contaminants of emerging concern, especially pharmaceuticals, and it represents a potential application in wastewater treatment of recalcitrant pollutants, such as fluoroquinolones, which are almost not abated by standard WWTPs. Although photodegradation partially contributes to alleviate their accumulation into the aquatic systems, heterogeneous photocatalysis assures complete sequestration and mineralization of FQs and their photoproducts and offers many advantages with respect to the other advanced oxidation processes (AOPs). The present brief review summarizes the most recent studies regarding the development and application of novel photocatalytic materials to the removal of FQs from contaminated waters. The collected data are arranged relating the mechanistic aspects to specific catalysts’ properties, such as adsorption capacity, easy recovery, and reusability, especially under actual conditions.

Les études médiévales après le tournant global
Authors: Ertl Thomas , Oschema Klaus 
Published: April 2022

Les études médiévales après le tournant globalCette contribution cherche à évaluer l’influence du « tournant global » sur les études médiévales, et notamment sur le Moyen Âge européen. Développer des perspectives globales pour la période prémoderne constitue un véritable défi. Tout d’abord, la notion même de « Moyen Âge » est un concept eurocentrique dont application à des contextes non européens peut être critiquée. Ensuite, si l’observation de contacts et de réseaux d’échanges de grande envergure a ouvert de considérables voies de recherche en histoire prémoderne, l’importance quantitative de ces contacts reste difficile à évaluer. Enfin, il existe une tension permanente entre différentes visions de la fonction de l’histoire (médiévale) dans la société. Malgré ces problèmes, les récentes contributions au « Moyen Âge global » ont ouvert de nouvelles approches à des phénomènes qui sont tout aussi pertinents pour les études médiévales européennes. Si le tournant global ne remodèle pas entièrement l’histoire de l’Europe médiévale, il ajoute certainement des nuances importantes et de nouvelles perspectives à de nombreux sujets qui non seulement résonnent avec les intérêts actuels, mais ont longtemps été une préoccupation de l’histoire médiévale européenne, comme la migration, le commerce et la religion. En dépit des difficultés et des défis (méthodologiques, linguistiques, etc.) qu’il pose, le tournant global a le potentiel de contribuer au développement de nouvelles approches thématiques ainsi que de nouvelles formes de coopération dans le domaine des études médiévales.
Migrations et tournant global de l’histoire européenne
Authors: Buettner Elizabeth 
Published: April 2022

Migrations et tournant global de l’histoire européenneLe tournant global est au cœur de l’étude des nombreuses histoires migratoires de l’Europe – qu’il s’agisse de migrations extra-, intra- ou infra-européennes – et inclut les espaces transatlantiques, impériaux et post-impériaux ainsi que d’autres arènes mondiales. Bénéficiant d’un grand nombre de travaux novateurs souvent centrés sur des histoires au niveau macro, cet article prône un cadrage plus serré portant sur les interprétations et les expériences individuelles. Ce faisant, il soutient que les historiens peuvent ouvrir des perspectives nuancées, qui risquent cependant d’être submergées au sein d’études où, paradoxalement, les migrants réels se trouvent supplantés en raison de l’accent mis sur les phénomènes migratoires globaux. Focalisé sur la fin de l’ère contemporaine, l’article retrace les dimensions globales de deux vies s’étendant sur près de deux siècles afin de soulever des questions plus larges, notamment sur la race et l’ethnicité. Jacob A. Riis (1849-1914) et Gérald Bloncourt (1926-2018) étaient d’éminents photographes documentaires qui partageaient un profond engagement pour la réforme sociale et l’amélioration des conditions de vie de la classe ouvrière. Ils ont tous deux enregistré des histoires de migration via leurs appareils photographiques et leurs écrits, permettant ainsi une analyse des représentations multimédias issues d’une même source. Le fait qu’ils soient eux-mêmes issus de la migration (Riis a quitté le Danemark pour les États-Unis, et Bloncourt Haïti pour la France métropolitaine) donne une résonance particulière aux images et aux textes qu’ils ont produits. Leurs propres origines et leurs vies mobiles se sont avérées cruciales pour leurs interprétations des flux de personnes plus larges qui ont relié l’Europe à différents contextes mondiaux – et qui continuent de le faire aujourd’hui.

Abstract
Understanding the meteorological drivers of extreme impacts in social or environmental systems is important to better quantify current and project future climate risks. Impacts are typically an aggregated response to many different interacting drivers at various temporal scales, rendering such driver identification a challenging task. Machine learning–based approaches, such as deep neural networks, may be able to address this task but require large training datasets. Here, we explore the ability of Convolutional Neural Networks (CNNs) to predict years with extremely low gross primary production (GPP) from daily weather data in three different vegetation types. To circumvent data limitations in observations, we simulate 100,000 years of daily weather with a weather generator for three different geographical sites and subsequently simulate vegetation dynamics with a complex vegetation model. For each resulting vegetation distribution, we then train two different CNNs to classify daily weather data (temperature, precipitation, and radiation) into years with extremely low GPP and normal years. Overall, prediction accuracy is very good if the monthly or yearly GPP values are used as an intermediate training target (area under the precision-recall curve AUC

$ \ge $

0.9). The best prediction accuracy is found in tropical forests, with temperate grasslands and boreal forests leading to comparable results. Prediction accuracy is strongly reduced when binary classification is used directly. Furthermore, using daily GPP during training does not improve the predictive power. We conclude that CNNs are able to predict extreme impacts from complex meteorological drivers if sufficient data are available.
Enhanced-efficiency nitrogen fertilizer boosts cauliflower productivity and farmers’ income: Multi-location and multi-year field trials across Nepal

Published: April 2022

SummaryEnhanced-efficiency nitrogen (N) fertilizers (EENFs) such as slow-release polymer-coated urea (PCU) and deep placement of urea briquettes (UBs) improve nitrogen use efficiency (NUE) by reducing N losses and increasing nitrogen uptake by plants. Multilocation field trials (81) with cauliflower were conducted across two agroecological regions covering seven districts during two crop-growing seasons between 2018 and 2020 to assess the potential of three EENFs, i.e., PCU, sulphur-coated urea (SCU) and UB for increasing curd yields, agronomic NUE (AEN) and economic benefits over conventional urea (CU). Results were compared with farmers’ current nutrient management practice (FP): applying CU at 58.5 kg N ha−1(ranging from 33 to 88 kg N ha−1). The N rates in three EENF treatments were 33% lower (100 kg N ha−1), considering their higher N use efficiency, than for CU (150 kg N ha−1). We hypothesize that EENFs produce similar or even higher yields compared with CU. For both years, all three EENFs resulted in significantly (p < 0.05) higher curd yields than CU (36.7 ± 1.1 t ha−1). PCU, SCU and UB increased yields by 21, 21 and 24% over those for CU. The yield increment was much higher (PCU, 44%; SCU, 43%; UB, 46%) than for FP. Similarly, PCU, SCU and UB increased the partial factor productivity of N (PFPN) by 91, 90 and 94% and the AENby 133, 129 and 138%, respectively, compared with CU. The gross margins of all three EENFs were similar: an average 25% more than with CU and 51% more than with FP. These results suggest that EENFs could help increase productivity and farmer income while considerably reducing N input, compared to use of CU. The government of Nepal should promote these EENFs by removing barriers to access for the associated fertilizers and foster their use through extension.

Summary
Low and slow adoption of innovative technologies among smallholder farmers in Tunisia is a key agricultural development problem partly related to the existing technology transfer approach used in the country. The objective of this study is to analyse how to design innovative technology transfer strategies more effective in terms of increasing female and male farmers’ adoption of an improved barley variety, ‘Kounouz’, for small ruminant nutrition. A randomised controlled trial method was used with farmers in Tunisia to implement four extension treatments and to evaluate their effects on adoption of Kounouz. Difference-in-difference estimates showed that intensive agricultural trainings can significantly improve adoption of Kounouz. Technical trainings combined with economic and organisational training and female empowerment courses resulted in a higher adoption rate. This finding has important policy implications, because it suggests that ensuring more widespread and equitable adoption of improved technologies may not require changes in the research system, but rather introduction measures that ensure better access for women to gender-sensitive extension programmes given their positive impacts on technology adoption of the household.
Accumulations and Cascades: Burmese Elephants and the Ecological Impact of British Imperialism
Authors: Saha Jonathan 
Published: April 2022

AbstractWhat effect did British imperialism in Myanmar have on frogs? And, given that the lives of these small amphibian creatures were rarely ever recorded or preserved in archival collections, how might we find out? Sceptical readers may also wish to take a step back and ask, why should historians even care about their lives? These are unusual questions for a historian to confront, but they are occasioned by the deepening conversation between ecology and history. This paper delves into the ecological impact of colonial rule in Myanmar through the lives of Burmese elephants and the creatures that they lived alongside. In it I argue that the concepts of ‘accumulation’ and ‘cascade’ are useful for enabling historians to apprehend the full extent of the impact of imperialism on the lives of animals.
