Quantification of uncertainty in 3-D seismic interpretation: implications for deterministic and stochastic geomodeling and machine learning
Authors: Schaaf Alexander , Bond Clare E.
Published: July 2019

Abstract. In recent years, uncertainty has been widely recognized in geosciences, leading
to an increased need for its quantification. Predicting the subsurface is an
especially uncertain effort, as our information either comes from spatially
highly limited direct (1-D boreholes) or indirect 2-D and 3-D sources (e.g.,
seismic). And while uncertainty in seismic interpretation has been explored in
2-D, we currently lack both qualitative and quantitative understanding of how
interpretational uncertainties of 3-D datasets are distributed. In this work, we
analyze 78 seismic interpretations done by final-year undergraduate (BSc)
students of a 3-D seismic dataset from the Gullfaks field located in the
northern North Sea. The students used Petrel to interpret multiple (interlinked)
faults and to pick the Base Cretaceous Unconformity and Top Ness horizon (part
of the Middle Jurassic Brent Group). We have developed open-source Python tools to
explore and visualize the spatial uncertainty of the students' fault stick
interpretations, the subsequent variation in fault plane orientation and the
uncertainty in fault network topology. The Top Ness horizon picks were used to
analyze fault offset variations across the dataset and interpretations, with
implications for fault throw. We investigate how this interpretational
uncertainty interlinks with seismic data quality and the possible use of seismic
data quality attributes as a proxy for interpretational uncertainty. Our work
provides a first quantification of fault and horizon uncertainties in 3-D
seismic interpretation, providing valuable insights into the influence of
seismic image quality on 3-D interpretation, with implications for deterministic
and stochastic geomodeling and machine learning.
La amistad en las películas de Pixar. Análisis en la construcción de la masculinidad y la feminidad
Authors: Cuenca Orellana Nerea
Published: July 2019

En la sociedad occidental se considera que el trabajo y el deporte son espacios masculinos y es a través de ellos donde los varones forjan sus amistades (Wasylkiv y Clairo, 2018: 1). En el lado de la feminidad, las amigas comparten emociones y confidencias (Migliaccio, 2014: 5). La amistad, por tanto, es una herramienta más para la división de género. Este tipo de relación es muy común en los contenidos audiovisuales destinados al público infantil porque cualquier individuo desarrolla amistades desde muy temprana edad. En el presente estudio de género nos adentramos en el análisis de las amistades de los protagonistas de los largometrajes Pixar estrenados entre 1995 y 2015 con el objetivo de definir en la masculinidad y la feminidad a través de la amistad.
Invisibilización de la mujer deportista en el twitter de los medios deportivos
Authors: Adá Lameiras Alba
Published: July 2019

El deporte femenino ha experimentado un gran crecimiento en los últimos años, pero la visibilidad en los medios sigue siendo escasa y estereotipada. Este estudio analiza la presencia de las deportistas y qué se dice de ellas en el Twitter de los Medios de Comunicación deportivos en España, analizando los medios generalistas (@ElPais_Deportes y @ABC_Deportes) y los específicos (@Marca y @MundoDeportivo) durante el mes de marzo de 2016. De los 964 tweets analizados, un 3.84% (N=37) trata sobre mujeres, de los cuales, un 54.05% (N=20) sobre mujeres deportistas y un 45.95% (N=17) sobre mujeres no deportistas. Además, el contenido de los tweets refuerza los estereotipos de género. Por lo tanto, los resultados evidencian que sí existe discriminación de género en el Twitter de los medios deportivos, dejando claro que, para las mujeres existen casi las mismas posibilidades de ser noticia tanto por méritos deportivos como por cuestiones personales.
"La Sépulture" di Gabriel Marie Legouvé da una prospettiva traduttologica: analisi e riflessioni. Proposta di una traduzione italiana ad opera di Giorgia Marangon
Authors: Marangon Giorgia
Published: July 2019

In questo articolo affrontiamo la difficile sfida di analizzare filologicamente La Sépulture di Gabriel Marie Legouvé per proporre ai lettori una traduzione italiana della sua elegia.

È importante sottolineare che la prima ed unica traduzione del poemetto francese in italiano è datata 1802, quattro anni appena dopo la pubblicazione dell’originale. Firma questa traduzione Luigi Balo­chi e la inserisce in una raccolta intitolata: Il merto delle donne, Le rimembranze, La malinconia e Le pompe funebri. La nostra, in sostituzione della traduzione – reinvenzione del Balochi, è una traduzione inedita del poemetto che pretende di restituire la lunghezza originale, quei 160 versi dimenticati da Balochi, rispettando, laddove possibile, la rima e il ritmo del verso francese.
Cenozoic Strike-Slip Tectonics and Structural Controls of Porphyry Cu-Mo and Epithermal Deposits During Geodynamic Evolution of the Southernmost Lesser Caucasus, Tethyan Metallogenic Belt
Authors: Hovakimyan Samvel , Moritz Robert , Tayan Rodrik , Melkonyan Rafael , Harutyunyan Marianna
Published: July 2019

The Zangezur-Ordubad mining district of the southernmost Lesser Caucasus is located in the central segment of the Tethyan metallogenic belt and consists of porphyry Cu-Mo and epithermal Au and base metal systems hosted by the composite Cenozoic Meghri-Ordubad pluton. Ore-hosting structures and magmatic intrusions are predominantly confined to a central N-S–oriented corridor 40 km long and 10 to 12 km wide, located between two regional NNW-oriented right-lateral faults, the Khustup-Giratagh and Salvard-Ordubad faults. The anatomy and kinematics of the main fault network are consistent with dextral strike-slip tectonics controlled by the NNW-oriented Khustup-Giratagh and Salvard-Ordubad faults.

Dextral strike-slip tectonics was initiated during the Eocene, concomitantly with final subduction of the Neotethys, and controlled the emplacement of the Agarak, Hanqasar, Aygedzor, and Dastakert porphyry Cu-Mo and Tey-Lichkvaz and Terterasar epithermal Au and base metal deposits. The Eocene structures were repeatedly reactivated during subsequent Neogene evolution in transition to a postsubduction geodynamic setting. Ore-bearing structures at the Oligocene world-class Kadjaran porphyry Cu-Mo deposit were also controlled by dextral strike-slip tectonics, as well as porphyry mineralization and its epithermal overprint hosted by an early Miocene intrusion at Lichk.

Eocene to early Miocene dextral strike-slip tectonics took place during NE- to NNE-oriented compression related to Paleogene Eurasia-Arabia convergence and subsequent Neogene postcollision evolution. Paleostress reconstruction indicates major reorganization of tectonic plate kinematics since the early Miocene, resulting in N-S– to NW-oriented compression. Early Miocene epithermal overprint at the Kadjaran porphyry deposit and left-lateral reactivation of faults and mineralized structures are linked to this late Neogene tectonic plate reorganization.

Published: July 2019

Climate change has brought about unprecedented new weather patterns, one of which is changes in extreme rainfall. In Kenya, heavy rains and severe flash floods have left people dead and displaced hundreds from their settlements. In order to build a resilient society and achieve sustainable development, it is paramount that adequate inference about extreme rainfall be made. To this end, this research modelled and predicted extreme rainfall events in Kenya using Extreme Value Theory for rainfall data from 1901-2016. Maximum Likelihood Estimation was used to estimate the model parameters and block maxima approach was used to fit the Generalized Extreme Value Distribution (GEVD) while the Peak Over Threshold method was used to fit the Generalized Pareto Distribution (GPD). The Gumbel distribution was found to be the optimal model from the GEVD while the Exponential distribution gave the optimal model over the threshold value. Furthermore, prediction for the return periods of 10, 20, 50 and 100 years were made using the return level estimates and their corresponding confidence intervals were presented. It was found that increase in return periods leads to a corresponding increase in return levels. However, the GPD gave higher return levels for 10 and 20 years compared to GEVD. While, for higher return periods 50 and 100 years, the GEVD gave higher return levels compared to the GPD. Model diagnostics using probability, density, quantile and return level plots indicated that the models provided were a good fit for the data.

The objective of this work was to accomplish the micromorphological characterization of the causal agent of the algal spot in ‘Amrapali’ mango trees. Therefore, ‘Amrapali’ mango leaves exhibiting symptoms of algal spots were used for making microscope slides, on which the pathogen somatic and reproductive structures were measured. The dimensions obtained for sporangiophores and sporangia were 245.5-545.6 × 10.5-19.1 μm and 21.4-34.2 × 16.3-24.7 μm, respectively. Descriptions based on symptoms and micromorphology indicated that the algae are Cephaleuros virescens, since this morphological data corroborates with literature descriptions. Besides, the algae had already identified by DNA sequencing as C. virescens.

Published: July 2019

The objectives in the present work were to identify maize double haploids one generation after chromosome duplication through the evaluation of phenotypic characteristics in thr field, flow cytometry and molecular markers SSR. The seeds used in the present study were obtained from a cross between four simple hybrids (DKB393, GNS 3225, GNS 3264, GNS 3032) and the KEMS inducer of gymnogenetic haploidy, used as a male parent. Seeds from this crossing were selected according to the R-Navajo marker and those considered haploid, were submitted to two different chromosome duplication protocols. Plants that survived to the chromosome duplication protocols were acclimatized in greenhouse and later transplanted to the field. After self-fertilization of the DH0 plants, the DH1 seeds obtained were seeded in the field, divided into treatments according to the parental and duplication protocols. At the vegetative stage V4 of the DH1 seedlings, leaf tissue samples were collected to identify ploidy via flow cytometry and DNA analyzes using microsatellite markers. These results were confronted with the morphological characteristics of the future DH1 plants developed in the field, evaluated with the use of descriptive tools. Statistical analyzes were performed using the generalized linear modeling approach and the exploratory and inferential analyzes of datas, by the use of graphical resources, barplot and boxplot. For the analysis of variance, were used the Student-Newman-Keuls test, and the Pearson's correlations. It was not observed uniformity of phenotypic characteristics of plants subjected to duplication protocols in the field and the use of descriptive tools in the morphological analysis of adult maize plants must be done carefully to avoid the wrong classification of determined genotypes related to the ployd. Flow cytometry must be used as screening in the identification of possible DH´s and the molecular markers SSR can be used to prove the genetically inherited KEMS lineage and also to identify the double-haploid corn plants.

Authors: Pedersen Holly F. , Beste-Guldborg Ann
Published: July 2019

Educating students who are deaf and hard of hearing (D/HH) is complex; compounding this complexity is the situation in rural areas, where the incidence levels are lower, students are more spread out, and the availability of specialty staff is more limited. The purpose of this mixed-methods action research study was to examine the impact of a collaborative consultation (CC) service delivery model on the knowledge and self-efficacy of school professionals who serve students who are D/HH in rural areas. A case study research design was used on a team of 3 school professionals from a rural school in the Upper Midwest. Findings indicated that CC increased the knowledge and self-efficacy of school professionals serving rural D/HH students. Implications for social change pertain to education administrators, inservice educators, and D/HH students.
Het incorporatiebeding: verleden, heden en toekomst
Authors: Beltzer Ronald
Published: July 2019

Since in the Netherlands only about a quarter of the employees is a member of a trade union, collective labour agreements are, in the majority of cases, legally binding not by law (i.e.: trade union members are automatically bound), but only by way of incorporation clauses in the labour contracts of employees. In this way, about 85% of employees is bound by the provisions of a collective labour agreement. The interpretation and application of such clauses have, in legal practise, at least partially a non-contractual character in order to accommodate other interests than the employee's freedom of contract. The author analyses legal practise regarding this matter and concludes that the non-contractual approach of incorporation clauses is under pressure, which threatens the system of collective labour law.
CAN IMMERSIVE VIRTUAL REALITY TRAVEL EXPERIENCE REPLACE REAL TRAVEL?
Authors: Polechoński Jacek , Tomik Rajmund
Published: July 2019

Purpose. The study attempts to define virtual reality in tourism as well as to characterise and present chosen applications created for the purposes of virtual sightseeing. Based on the survey conducted among tourism and recreation students of the Jerzy Kukuczka Academy of Physical Education in Katowice, the study attempts to answer the provocative question: “can virtual tourism replace real-world travel?”, and to analyse participants’ opinions on the topic of virtual trips. Methods. Analysis of scientific studies as well as information and data on the possibility of using immersive virtual reality in human life with particular consideration given to tourism. An overview of applications enabling taking trips through immersive exploration of virtual environments. The survey was conducted among AWF students. Participants expressed their opinions about virtual sightseeing. Findings. Virtual reality is increasingly used in various fields of human life. It is entering the world of tourism, in which it is used to create presentations of hotels and resorts, and to promote towns and tourist facilities. Appropriate software and IT equipment allow to take deliberate, planned and very realistic virtual trips. The authors of the work defined such tourism as all activities carried out by persons who immerse themselves in virtual reality for learning and entertainment purposes in order to experience the illusion of change of their everyday, real surroundings in time and space. Tourism understood in such a way allows us not only to go to almost any place without the necessity of leaving home. It also allows for visiting areas and objects which cannot be explored in real life. It enables a visitor, among others, to travel in space and visit historical sites which no longer exist in their original form, but have been recreated in computer applications. Virtual tourism also allows for exploring fictional locations created by designers of photorealistic graphics as well as valuable and sensitive monuments, and taking trips to places which are dangerous or prohibited. In the conducted survey, it has been concluded that even though tourism and recreation students found experience with virtual reality to be positive, the majority is not convinced that this form of tourism can replace real-world travel. Research and conclusions limitations. There are only a few publications concerning immersive virtual reality travel experience. Access to the software was quite early. Practical implications. Understanding and reorganisation of issues related to immersive virtual reality travel experience. The study may constitute an original introduction and encouragement to carry out qualitative and quantitative research on newly created virtual tourism. Originality. An original concept of understanding virtual tourism was presented. Type of paper. Empirical research and review.

Authors: Nalazek Mirosław
Published: July 2019

Purpose. Identification of changes taking place in passenger air transport within a geographical context, analysis of factors affecting changes, assessment of their impact. Methods. Desk research. Analysis of foreign and domestic literature. Findings. The research revealed very significant changes in the spatial distribution of passenger air transport in 2005-2017. The Asian-Pacific region has become the largest region in terms of the number of transported passengers. The North American region has lost its position as the leader. The position of the Asian-Pacific region results from the rapid growth of passenger transport in countries such as China, India and Indonesia. The most important factors affecting changes in spatial distribution are: changes in the level of economic development, demographic changes, deregulation of air transport and its result, the development of low-cost airlines. Research and conclusions limitations. The availability and validity of statistical data in many important markets of air transport services is limited, a great impediment being the lack of data on the number of flights among residents carried out in some of the analysed countries. Practical implications. The research and conclusions formulated are the basis for determining development trends in tourism, especially international tourism. Originality. There is no review in the Polish literature analysing changes in world air transport. In synthetic form, the work presents the most important trends in this area regarding geographical layout. Type of work. Scientific review article.
UNDERTAKING MOUNTAIN TOURISM BY RESIDENTS OF THE WEST POMERANIAN VOIVODESHIP
Authors: Umiastowska Danuta , Kisiel Marta
Published: July 2019

Puropse. Participation in mountain tourism can be undertaken in various ways. A wide range of possibilities offered by mountain areas results in preferred forms of movement having changed over the years. Mountain tourism also depends on the season of the year, because weather conditions are conducive to skiing or cycling, climbing or hiking, strong stream currents associated with large rivers, allows for participation in canoeing or rafting. The geographical location of the West Pomeranian Voivodship is not a factor conducive to short-term trips to mountain towns, hence the attempt understand the interest in mountain tourism for those living there. The presented work attempts to find an answer to the question as to how the participation of the inhabitants of the West Pomeranian Voivodeship, in various forms of mountain tourism, has changed over the years? Two research hypotheses regarding the factors differentiating the decision to rest in the mountains were formulated. The research carried out among students of West Pomeranian schools, students of universities in Szczecin and adults, allowed for the comparison and analysis of preferences regarding the choice of forms of physical activity undertaken in mountain areas. Methods. In empirical research using a questionnaire, opinions were collected among 3,224 people of different ages living in large and small towns and in the villages of the West Pomeranian Voivodeship. Based on the analysis of documents, information on organising trips in advance was obtained. Findings. Research has shown that students are the most numerous group taking part in mountain tourism. A small percentage of respondents take family trips to the mountains. There was also a decreasing interest of West Pomeranian educational institutions in mountain areas as a place for organised travel. Research and conclusions limitations. Empirical research covered the residents of only one province. Practical implications. Diagnostic tests. Paying attention to the insignificant role of mountain tourism in the school educational process as preparation for lifelong physical activity Originality. Studies on similar subjects in the West Pomeranian Voivodeship have not been conducted. Type of paper. Empirical research.

Published: July 2019

Purpose. The aim of this work is to accurately diagnose risk factors, determine and evaluate existing legal regulations for tourist foot-orienteering competitions set in mountain areas , and to develop procedures for organisers of these events. Methods. Analysis of documents was used as the main method in the work. In addition, the design method was used. Results. The most important factors determining the safety of participants and organisers of competitions in foot tourist forms of orienteering competitions in mountain areas have been diagnosed. In light of the analysed documents, it seems that the activities undertaken by the organizers of this type of events in our country so far, question the existence of certain standards as to how to proceed in the field of safety management. Therefore, a matrix was developed to minimise risk factors for participants and the organisers of these events. Research and conclusions limitations. The limitation of the research results from the lack of verification of the proposed tools in practice. It would be advisable in the future to supplement the material with questionnaire surveys carried out among participants and organisers of such events, as well as expert observations during competitions. Practical implications. Both participants and organisers of the competition can use this material to reduce the risk of undesirable phenomena or to minimise their effects. In addition, this text can be used as a source for tourist foot-orienteering event organisers. Originality. No papers of similar content in Polish or English were found. Type of paper. The work contains conceptual elements related to the creation of tools useful in risk prevention for participants and organisers regarding tourist foot-orienteering competitions held in mountain areas.

Published: July 2019

In this study we describe a new species of the click-beetle genus Lacon Laporte, 1838 from the relict Hyrcanian forest in northern Iran. Lacon mertliki sp. nov. is morphologically similar to L. lepidopterus (Panzer, 1801) but differs from the latter in the body coloration and pubescence, the shape of pronotum and scutellar shield, and male and female genitalia. We provide brief data on its ecology as well as an identification key to all Lacon species in Iran. Additionally, we synonymize Lacon nadaii Platia & Németh, 2011 with Lacon unicolor (Candèze, 1874).

Published: July 2019

O presente trabalho teve como objetivo analisar o comportamento do milho híbrido em termos de crescimento e produtividade quando fertilizado com urina humana. O delineamento experimental utilizado foi o de blocos ao acaso com cinco tratamentos. Os tratamentos aplicados foram: T1 - água bruta e adubação orgânica; T2 - água bruta e adubação química e orgânica, T3 - água bruta e urina na dose recomendada; T4 - água bruta e metade da dose de urina recomendada; T5 - água bruta e 1,5 da dose de urina recomendada. O volume de urina aplicado foi calculado a partir da demanda nutricional da cultura do milho e da concentração de nitrogênio na urina humana resultando no valor 1,0 litro por metro linear para o tratamento - T3. A área cultivada com milho foi irrigada por gotejamento, sistema selecionado por ser um dos mais utilizados pelos agricultores rurais. ­ Com relação às variáveis, altura da planta e índice de espiga não houve diferença significativa (p>0, 05) quando se comparou os tratamentos estudados. Por outro lado, os resultados da pesquisa indicaram que o peso das espigas variou conforme o tipo de adubação (química ou urina) e quanto ao volume de urina aplicado, ocorrendo efeito entre aplicar urina na taxa de 1,5 ou 1 e aplicar urina na taxa de 0,5 ou adubo químico (p<0,05). A urina se mostrou como um potencial praguicida à lagarta-do-cartucho (Spodoptera frugiperda), pois nenhuma das plantas que recebeu este tratamento foi acometida por tal praga, a qual prejudicou a produtividade do tratamento com NPKS. Do ponto de vista experimental, o presente estudo evidenciou resultados promissores acerca da utilização de urina humana na fertilização de Zea mays.

Moisture contents ranged from 5.33 ± 0.06% - 8.33 ± 0.06%, ash (23.07 ± 0.06% - 61.27 ± 0.06%), fat (1.13 ± 0.06% - 3.37 ± 0.06%), crude fibre (2.43 ± 0.12% - 22.03 ± 0.06%), and crude protein (18.50 ± 0.10% - 55.23 ± 0.06%). The functional properties of vegetables were close in term of high protein level indicating that they are more nutritious. Also, the level of their ash content showed that the vegetables are very rich in essential minerals for healthy life when compared with one another and recommended dietary allowance (RDA). Thus, there is a need for farmers in the area to engage in dry season vegetable production so as to ensure availability of leafy vegetables throughout the year.

The HIV-1 reverse transcriptase (RT) is a major target for drug development. Inhibition of this enzyme has been one of the primary therapeutic strategies in suppressing the replication of HIV-1. A series of 2-amino-6-arylsulfonylbenzonitrile derivatives were subjected to quantitative structure-activity relationship (QSAR) analysis. Very recently, we proposed the use of substituent electronic descriptors (SED) instead of the electronic descriptors of whole molecules as new and expedite source of electronic descriptors. In this study, we used SED parameters in QSAR modeling of anti HIV-1 activity of 6-arylsulfonylbenzonitrile derivatives. In SED methodology produces a vector of electronic descriptors for each substituent and thus a matrix of SED is generated for each molecule. Consequently, a three-dimensional array is obtained by staking the data matrices of different molecules beside each other. As a novel multiway data analysis method, molecular maps of atom-level properties (MOLMAP) approach was also used to transfer a three-dimensional array of SED descriptors into new two-dimensional parameters using Kohonen network, following by genetic algorithm-based partial least square(GA-PLS) to connect a quantitative relationship between the Kohonen scores and biological activity.In unfolding data, HOMO1, HOMOB1, SOFB1 and EPHA4 represent the most important indices on QSAR equation derived by PLS analysis. Accurate QSAR models were obtained by both approaches. The resulted GA-PLS model of MOLMAP approach possessed high statistical quality r2= 0.83 and q2=0.70. It could explain and predict about 70% of variances in the anti-HIV1 inhibitory activity of the studied molecules. However, the superiority of three-way analysis of SED parameters based on MOLMAP approach with respect to simple unfolding was obtained.

Leachates from dumpsite basically contain a wide range of heavy metals and selenium. However, heavy metals have negative public health and environmental impacts once the leachates are allowed to infiltrate into groundwater. This is one of the oldest, growing problems threatening the surrounding globally. Therefore, it is imperative to quantify the information on the environmental impact of heavy metal and selenium levels, and suggesting various techniques that could be used to clean-up their concentrations from the environment to the minimum to ameliorate the plight of the people. The aim of this study was to determine the concentration of heavy metal and selenium levels in leachate of Central Bank of Nigeria dumpsite along University of Agriculture Road-Makurdi and also to investigate their levels in soil around the dumpsite platform. The concentrations of some heavy metals such as Chromium (Cr), Lead (Pb), Cadmium (Cd), Mercury (Hg) and non metal Selenium (Se) levels in leachate from Central Bank of Nigeria Dumpsite platform and surrounding soil along University of Agriculture road, Makurdi, were determined using Atomic absorption spectrophotometry (Flame AAS) for Cr, Pb and Cd while cold vapour and hydride generation were used for Hg and Se respectively. The soil samples were collected at different depths (cm) 0 – 20, 20 – 40, 40 – 60 and 60 – 80. The levels of all heavy metals and non metal selenium in this study area were found to be higher than those of the control samples. The total mean concentration of the soil samples analysed for each metal and selenium levels at different depths range from Cr (74.7 – 2.6 mg/kg), Cd (7.41 – 0.6 mg/kg), Hg (4.45 – 1.4 mg/kg), Se (2.04 – 1.2 mg/kg) and Pb (8.53 – 1.7 mg/kg). The concentrations in leachates were Cr (0.079 mg/L), Cd (0.010 mg/L), but Pb, Hg and Se were not detected. The concentrations of Cr and Cd determined in leachate were below the WHO standard limits. Similarly, the concentrations of Pb, Hg and Se in soil analyzed in this study were within the permissible limits. However, the concentration of Cr and Cd were found to be higher than the permissible limits due to the increasing anthropogenic activities in the area. Awareness of the level of soil and leachate pollution around the dumpsite needs to be created urgently especially among people living in the environment. Proper and effective waste management plan should be developed and implemented.

In this work the formation of vinylphosphines was studied through the hydrophosphination reaction. The study aims to rationalize the stereoselectivity of these compounds using quantum DFT methods. This theoretical study of chemical reactivity was conducted at B3LYP/6-311 + G (d, p) level. Global chemical reactivity descriptors, stationary point energies and activation barriers were examined to foretell the relative stability of the stereoisomers formed. The various results obtained have revealed that the addition of arylphosphine to dihalogenoacetylene is stereospecific. The Trans form of vinylphosphines is more stable than the Cis form, when the substituent on phosphorus generates less or no π-conjugations. On the other hand, the Cis isomer is predominant when the aryl radical favors more π-conjugations. The theoretical results obtained are in agreement with the experimental results.

The use of vegetable oils as a renewable source for the production of ecofriendly biolubricant is gaining the attention of the renewable energy researchers and lubricating oil producers. This study evaluates the quality assessment parameters of ecofriendly biolubricant from waste cooking palm oil (WCPO). The crude WCPO was filtered, centrifuged at 500 rpm, and dried over Na2SO4 crystals overnight. The quality assessment parameters of the pretreated WCPO (PWCPO) were determined to authenticate its potential for the production of multigrade lubricating oils. Kinematic viscosities at 100°C (8.26±0.03 cSt) and 40°C (36.98±0.01 cSt) were determined according to ASTMD-446 method, while the viscosity index (208±0.11) was determined according to ASTMD-2270 method. A design of experiment (Mixture Design Method using Minitab 17) was used to determine the proportion of PWCPO (68.75%), SN 500 (23.75%), and additives (7.50%) that gave the mixture with the optimum quality parameters of the produced biolubricant. The produced biolubricant had kinematic viscosities at 100oC (10.72±0.13 cSt) and 40°C (59.32±0.20 cSt) respectively, a viscosity index of 173±0.10, flash point of 234±1.13°C, pour point of -31±0.10°C, acid value of 21.04±1.21 mg KOH g-1, and iodine value of 1.28±1.40 mg I2 g-1. The produced biolubricant has quality parameters that are comparable to available ecofriendly lubricating oil and was also found within standards for engine oils.
