Enhancing Oil Recovery with Hydrophilic Polymer-Coated Silica Nanoparticles
Authors: Bila Alberto , Torsæter Ole
Published: September 2020

Nanoparticles have been proposed for enhanced oil recovery (EOR). The research has demonstrated marvelous effort to understand the mechanisms of nanoparticles-EOR. Nevertheless, gaps still exist in terms of understanding the improved fluids and fluid-rock interactions by nanoparticles, which are the key driving forces for oil mobilization. This paper investigates four types of polymer-coated silica nanoparticles as additives for water flooding oil recovery in water-wet reservoirs. A series of flooding experiments were performed with nanoparticles at 0.1 wt.% in seawater at ambient conditions. The dynamics of fluids, fluid-rock interface interactions and fluid flow behavior were characterized in order to understand oil recovery mechanisms of nanoparticles. Experimental results showed an increase in oil recovery up to 14.8%-point with nanofluid injection compared to an average of 40% of the original oil in place (OOIP) obtained from control water flood test. Moreover, the nanoparticles mobilized residual oil and incremented oil recovery up to 9.2% of the OOIP. Displacement studies show that no single mechanism could account for the EOR effect with the application of nanoparticles. Instead, the mobilization of oil seemed to occur through a combination of reduced oil/water IFT, change in the rock surface roughness and wettability to more water-wet, and microscopic flow diversion due to clogging of the pores.

Published: September 2020

Climate change plays a pivotal role in the hydrology of tributaries in the upper Blue Nile basin. This study was designed to reveal the extent to which climate change impacts on stream flow of the Gumara watershed under the Representative Concentration Pathway (RCP) climate change scenario. The study considered the RCP 2.6, RCP 4.5 and RCP 8.5 scenarios using the second generation Canadian Earth System Model (CanESM2). The Statistical Downscaling Model (SDSM) was used for calibration and projection of future climatic data of the study area. Soil and Water Assessment Tool (SWAT) model was used for simulation of the future stream flow of the watershed. Result showed that the average temperature will be increasing by 0.84oC, 2.6oC and 4.1oC in the end of this century under RCP 2.6, RCP 4.5 and RCP 8.5 scenarios respectively. The change in monthly rainfall amount showed a fluctuating trend in all scenarios but the overall annual rainfall amount is projected to increase by 8.6%, 5.2% and 7.3% in RCP 2.6, RCP 4.5, and RCP 8.5 respectively. Overall, this study revealed that, due to climate change, the stream flow of the watershed is found to be increasing by 4.06%, 3.26%, and 3.67% under RCP 2.6, RCP 4.5 and RCP 8.5 scenarios respectively.
GEO-GEO Stereo-Tracking of Atmospheric Motion Vectors (AMVs) from the Geostationary Ring
Authors: Carr James L. , Wu Dong L. , Daniels Jaime , Friberg Mariel D. , Bresky Wayne , Madani Houria
Published: September 2020

Height assignment is an important problem for satellite measurements of Atmospheric Motion Vectors (AMVs) that are interpreted as winds by forecast and assimilation systems. Stereo methods assign heights to AMVs from the parallax observed between observations from different vantage points in orbit while tracking cloud or moisture features. In this paper, we fully develop the stereo method to jointly retrieve wind vectors with their geometric heights from geostationary satellite pairs. Synchronization of observations between observing systems is not required. NASA and NOAA stereo-winds codes have implemented this method and we have processed large datasets from GOES-16, -17, and Himawari-8. Our retrievals are validated against rawinsonde observations and demonstrate the potential to improve forecast skill. Stereo winds also offer an important mitigation for the loop heat pipe anomaly on GOES-17 during times when warm focal plane temperatures cause infra-red channels that are needed for operational height assignments to fail. We also examine several application areas, including deep convection in tropical cyclones, planetary boundary layer dynamics, and fire smoke plumes, where stereo methods provide insights into atmospheric processes. The stereo method is broadly applicable across the geostationary ring where systems offering similar Image Navigation and Registration (INR) performance as GOES-R are deployed.
An Institutional Analysis of the Rise of Benefit Corporations Outside of the US: The Case of Italy
Authors: Arena Marika , Bengo Irene , Gerli Francesco , Colzani Paola
Published: September 2020

This paper contributes to the current debate about Benefit Corporations, presenting the development of this organisational model in Italy, the first country to introduce this hybrid form after the US. Grounded on an institutional logic perspective, it provides a picture of the institutional dynamics that have characterised the rise of this new entrepreneurial form outside the US. The analysis provides an in-depth foundational study of the Italian case and highlights the relevant influence of different institutional pressures in explaining the rise of and constraints in the diffusion of Benefit Corporations. Empirically, it combines secondary data, available from different public sources, and primary data collected through interviews with a series of knowledgeable informants. Based upon the analysis, two aspects appear peculiar for the development of Benefit Corporations in Italy: the interplay between the Benefit Corporation legal form and the certified B Corp model, and the rise of tensions between social entrepreneurship and the third sector ecosystem. This paper concludes that the peculiar institutional pressures leading to the birth of Benefit Corporations in Italy may be source of permanent tensions and of concern for the diffusion of the model.
Systemic Sustainable Development in the Transport Service Sector
Authors: Sztangret Izabela
Published: September 2020

The concept of sustainability and sustainable development, especially systemic sustainable development, still raises controversy in literature. The article makes an attempt to re-examine these concepts from a systems perspective, seeking foundations and applications in the selected sector. It is becoming increasingly clear that sustainability and sustainable development are aimed at integrated economic, social, cultural, political, and ecological factors [1[,[2] (pp.641-642). This causes that the constructive approach to the issue is required, taking into account all the actors, areas and dimensions involved in the pursuit of systemic sustainable development. As a result, both local and global dimensions and the way they interact must be explored in a multi-faceted manner in order to offer a perspective more useful than other analytical approaches, because the systems view is a way of thinking in terms of connectedness, relationships, and context [3]. The article aims to review selected publications and studies so as to form the general idea of systemic sustainable development and define the systemic development of sustainable transport, including in particular the perspective of the actors of the sector, transport providers (passenger, urban) and transport development program, implemented both by local governments and on the European scale. An attempt was made to identify elements of the systemic sustainable development model, setting it in the reality of the following subcategories: “Society”, “Economy” and “Environment” in sectoral terms. It is supposed that, systemic sustainable development is a conglomerate of public administration entities, companies operating in the sector, individual and corporate customers, acting in certain conditions for economic, social and environmental well-being, and a number of their initiatives of major or minor significance, grouped in six sub-areas, undertaken to achieve systemic value in the examined sector, with a positive or negative business/economic, social and environmental impact.
The Effect of Hysteroscopy on the Reproductive Outcomes of Infertile Women Without Intrauterine Pathologies: A Systematic Review and Meta-Analysis
Authors: Yang Soo Yeon , Lee Seon Heui , Chon Seung-Joo
Published: September 2020

(1) Background: The aim of this work was to systematically review existing studies on whether hysteroscopy improves the reproductive outcomes of women with infertility even in the absence of intrauterine pathologies when compared to women who did not receive a hysteroscopy. (2) Methods: We established the Participant-Intervention-Comparison-Outcome strategy and used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement to conduct a systematic review of 11 studies which were retrieved from 3 electronic databases: Ovid-Medline, Ovid-Embase, and the Cochrane Library. Two independent investigators extracted the data from the included studies and used the Cochrane risk-of-bias tool to assess their quality. (3) Results: The primary outcome measures were the clinical pregnancy rates (CPRs) and live birth rates (LBRs) in the in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) cycles. Hysteroscopy in infertile women without intrauterine pathologies showed higher CPRs and LBRs than those in the same population who did not receive hysteroscopy in cases of recurrent implantation failure and IVF (odds ratio: 1.79 and 1.46, 95% confidence interval: 1.46-2.30 and 1.08-1.97 for CPR and LBR, respectively); however, the degree of significance was not as high for LBR. (4) Conclusions: Hysteroscopy before IVF/ICSI in infertile women without intrauterine pathologies may potentially be effective in improving the CPRs and LBRs in patients with RIF. Robust and high-quality randomized trials are warranted to confirm this finding.

Published: September 2020

A new cocrystal salt of metformin, an antidiabetic drug, and N,N’-(1,4-phenylene)dioxalamic acid, was synthesized by mechanochemical synthesis, purified by crystallization from solution and characterized by single X-ray crystallography. The structure revealed a salt-type cocrystal composed of one dicationic metformin unit, two monoanionic units of the acid and four water molecules namely H2Mf(HpOXA)2∙4H2O. X-ray powder, IR, 13C-CPMAS, thermal and BET adsorption-desorption analyses were performed to elucidate the structure of the molecular and supramolecurar structure of the anhydrous microcrystalline mesoporous solid H2Mf(HpOXA)2. The results suggest that their structures, conformation and hydrogen bonding schemes are very similar between them. To the best of our knowledge, the selective formation of the monoanion HpOXA⁻, as well as its structure in the solid, is herein reported for the first time. Regular O(-)∙∙∙C(), O(-)∙∙∙N+ and bifacial O(-)∙∙∙C()∙∙∙O(-) of n→* charge-assisted interactions are herein described in H2MfA cocrystal salts which could be responsible of the interactions of metformin in biologic systems. The results, support the participation of n→* charge-assisted interactions independently, and not just as a short contact imposed by the geometric constraint due to the hydrogen bonding patterns.

Published: September 2020

We investigate, whereas the SU(4)/SU(2) model, is viable for describing strong interactions. The existing problems of confinement and asymptotic freedom, two phenomena that can not be described by the SU(3) model, might indicate that we need something "larger" than the SU(3) model. The considered coset SU(4)/SU(2) or the Stiefel manifold V^2(C_4) contains an su(3) algebra, plus additional degrees of freedom that resembes the Feddev-Poppov concept. The richer structure of this coset, give us enough room, to seek for new phenomena, as its dimensionality is 12. The consideration of the SU(4)/SU(2) model flavors firstly the unification of nuclear fields (strong and weak) in an SU(4) model.

Desejo por filhos entre mulheres de alta escolaridade: conflitos, mudanças e permanências
Authors: Simão Andrea Branco , Zanatta Coutinho Raquel , Ramalho Guedes Gilvan
Published: September 2020

Este trabalho analisa as percepções e os significados da maternidade para um grupo de mulheres de alta escolaridade, casadas ou em união consensual, com no máximo um filho, residentes em um município mineiro de porte médio. Os dados provêm de 16 entrevistas semiestruturadas, realizadas em 2018 no município de Governador Valadares, MG. Os resultados indicam que, embora a maternidade seja um acontecimento desejado e valorizado, a decisão dessas mulheres não é isenta de dúvidas em relação às dificuldades para conciliar um filho com o desejo de liberdade e crescimento profissional. Essas dúvidas decorrem do fato de a maternidade ainda ter um lugar de destaque na vida das mulheres, mesmo entre um grupo de vanguarda, e se tornar mãe permanece tendo um efeito expressivo em suas vidas. Os conflitos gerados pela concomitância entre a permanência do desejo relacionado à maternidade e a emergência de novos projetos individuais apresentados às mulheres desafiam a lógica tradicional que relaciona escolaridade e projetos reprodutivos.

Seed has an important role  to  increasing  the  productivity of  food crops and has has a lot of legislation issued by the government relating to seed. However, to date there are no known legislation from local government (PEMDA) on seed (specific location).  At the current stage, the existing local legislation on seed was based on the initial legislation from the central government especially Cultivation Act No. 12/1992 and Government Legislation No.44/1995. To date the most important institution based on  the  existing  legislation  on  seed  is  BPSBTPH  (Seed  Control  and  Certification Services  Agency  for  Food  Crops  and  Horticulture).  BPSBTPH  has  a  function  to control  and  be  responsible  in  seed  production,  from  procurement,  distribution  and trading  activities.  To  optimize  their  role  and  function  the  BPSBTPH  should:  (1) develop policy for agricultural enterprises or farmers who have been used un-labelled seed; (2) participate in supervising new seed products from other agencies; (3) more focus on supervising duties and less pressure on achieving target in production that was set by local government.

Abstract : Seed is one of th

e main elements in rice cultivation. Use of seed labeled and
quality will have a positive impact on productivity. This strategic role of seed which is
the reason the government helps farmers by conducting seed subsidies. Subsidization
of seed carried out throughout Indonesia and one of them is the province of South
Sumatra. The objective is to see the implementation of subsidized seeds with the main
focus of the implementation challenges and solutions such activities. By 2016 subsidy
survay seed at the time of implementation was not up to 10 percent. The main cause of
this low uptake by PSO is a delay DUPBB that the main basis of PSO prepares and
provides rice seeds. Despite the low uptake but seed subsidies still need to be passed
on, this is due to the use of seed labeled and quality in South Sumatra Province is still
low, and to overcome implementation seed subsidies in the future need to be increased
dissemination activities, the introduction of new varieties of R & D, the certainty of
the selection of varieties, increasing the number of seeds subsidized and incentives for
enumerators DUPBB.

Abstrak : Benih merupakan salah satu unsur utama dalam budidaya padi. Pemakaian
benih berlabel dan bermutu akan memberikan dampak positif pada produktivitas.
Peranan benih yang strategis ini merupakan alasan pemerintah membantu petani
dengan melaksanakan kegiatan subsidi benih. Pemberian subsidi benih dilakukan
diseluruh Indonesia dan salah satunya adalah Provinsi Sumatera Selatan. Tujuan
penulisan ini adalah melihat pelaksanaan subsidi benih dengan fokus utama kendala
dan solusi implementasi dari kegiatan tersebut. Pada tahun 2016 subsidi benih pada
saat dilakukan survay pelaksanaannya tidak sampai 10 persen. Penyebab utama
serapan rendah ini menurut PSO adalah keterlambatan DUPBB yang menjadi dasar
utama PSO menyiapkan dan memberikan benih padi. Meskipun rendah serapan tetapi
subsidi benih masih perlu diteruskan, hal ini disebabkan pemakaian benih berlabel dan
bermutu di Provinsi Sumatera Selatan masih rendah, Dan untuk mengatasi kendala
implementasi subsidi benih kedepannya perlu ditingkatkan sosialisasi kegiatan,
pengenalan varietas baru litbang, kepastian pemilihan varietas, penambahan jumlah
benih yang disubsidi dan pemberian insentif bagi petugas pendata DUPBB.
