Word Association and Its Function at the Constituent Understanding on the Language Learning
Authors: Prihatini Arti
Published: February 2020

This paper aimed at describing word association and its function at the constituent understanding on the language learning. Word association is a relation between a word with other words because of the semantic relationship. A word association test appears when there is a stimulus word and someone mentions a response word that comes to mind firstly based on the stimulus word. The response words show someone’s mental lexicon as a result of language acquisition and language learning. Word associations can be used in the process of understanding constituents (linguistic units) with word association tests, they are (1) words, (2) phrases, and (3) sentence patterns. In word constituent learning, word association tests are carried out by asking questions so that the result can show the semantic networks of words that are classified by word type. Phrase constituent learning is also held by asking questions, but response words are included before or after the stimulus word so that these words form a phrase. Meanwhile, sentence constituent learning is held by presenting words that are located as predicate and then asking questions that bring up the subject, object, complement, or additional information that accompany the predicate. With this method, students do not only learn constituents as units that have levels from small (words) to large ones (sentences), but also understand that constituents have a patterned and interconnected system.

A Perception of Javanese Philosophy based on Serat Wedhatama toward Virgil's Symbol of Human Wisdom and Role in Dante Alighieri's Inferno
Authors: Mahisa Akhtabi Petrik , Fariha Inayatul
Published: February 2020

Virgil in Inferno is claimed to be a perfect example of human being concerning to his mastery of maturity and rationality viewed from the perspective of western philosophy as phrased in ‘Love of Wisdom’. As we know, the wisdom taught by western philosophy is the most important thing in someone who philosophies because western sees efforts as an absolute thing in human philosophizing process rather than its result or the truth itself. As believed by western, wisdom can be acquired by practicing and thinking which then the result is human with high intellectual and ethical attitude as depicted by Virgil in Inferno. On the contrary, a different concept stated by Javanese philosophy which truth is the absolute one whereas effort is only a means as stated by the phrase ‘Love of Perfection’. Relying on the belief in God, Javanese philosophy states that perfect human is person who understand the existence of God, the unity of man and God as termed by manunggaling kawula gusti. Human ethics and wisdom have only been destined along with the maturity of one’s age and spiritual attitude. Therefore, Javanese philosophy based on Serat Wedhatama used as the perspective of reading and interpretation to expand the exploration toward Virgil’s role and symbol, also structuralism which is used as a method of extracting pieces of evidence based to Virgil’s action and speech in relation with that two philosophical concept. Not merely to expand exploration, the use of that two philosophy concept is to compare those different values in discussing Virgil in Inferno.

Wayang Golek Reog Ponorogo: The Acculturation of Indonesian Culture As Patriotism Character Education Learning Medium to Early Age Children
Authors: . Sulton , Yulia Wulansari Betty , Sinta Utami Prihma
Published: February 2020

Indonesian society deals with a decline of patriotism. Foreign culture comes in with Access 4.0 influencing young generation rapidly. People start leaving traditional arts as an eastern cultural heritage. One of the examples is that many people do not know the legendary story of the origin of Reog Ponorogo but the dance. Early childhood education is one of the important agents to preserve Indonesia’s cultural heritage. One of them is done through Wayang Golek Reog Ponorogo. Wayang golek is an acculturation of West Java and East Java cultures. It comes from Priangan arts in West Java, whereas here, wayang golek is created with the legend of the origin of Reog Ponorogo. Containing authentic Indonesian arts, Wayang Golek Reog Ponorogo provides an advantage as a Learning Medium of Patriotism Character Education. This medium has two functions of character education, namely (1) the introduction of Indonesian cultural arts, namely Wayang Golek Reog Ponorogo as one of Indonesia’s wealth and (2) the developed manuscript story contains many character values that can be interpreted by the audience. This medium is expected to be one of the learning media innovations for early childhood in increasing patriotism of Indonesian people.

Online Marketplace Characteristics for Freelance Designers
Authors: . Yon Ade Lose Hermanto
Published: February 2020

Marketplace is one of the choice places for designers to market the products they create. Online Marketplace is a networking site or application on a gadget that provides online trading facilities from various sources. In the marketplace, application owners or website networks only provide facilities for users to display products sold. In addition, the marketplace owner also provides facilities in the form of bridging online transactions between sellers (designers) and buyers. In utilizing the marketplace, designers must know the needs and desires and design market trends. Because with accurate data related to needs, trend design will greatly help designers to create design products that are suitable for the market. Not only the idealism of designers in making works, but also still relies on dynamically changing demands.
This study intends to determine the design trends that are in accordance with the desires and needs of the graphic design market so that they can help designers determine the making of works sold in the marketplace. This study uses a qualitative research approach to explore all phenomena that occur in the world of online design marketplace. Through this qualitative approach, researchers will understand social reality, see what conditions exist in the sale and purchase of design products and design trends that are popular in society. This qualitative approach is sought to be directed at identifying the trend design and style design that designers need for the basis of making designs that can be sold in the marketplace.

Authors: Zimdars Eduardo Rafael , Munhoz Regina Helena
Published: February 2020

Este artigo teve como objetivo analisar as possíveis influências da Pedagogia da Assimilação Solidária (AS) no processo de ensino e aprendizagem de Limites em uma turma de Cálculo I. A AS é uma proposta alternativa de ensino, contrapondo o ensino tradicional de matemática, proporcionando que os estudantes recebam bônus, em notas, pelo trabalho de aprendizagem realizado em grupo, sem relação com a nota da avaliação. O trabalho de aprendizagem se dá pelo tempo que o grupo permaneceu discutindo e resolvendo situações-problema, sem considerar quantos problemas resolveu corretamente. Para determinar as formas de promoção e avaliação é necessário um contrato de trabalho, discutido e aprovado pela maioria dos estudantes de forma democrática. O trabalho de aprendizagem de cada aula é baseado em uma ficha de trabalho, composta por problemas sobre o tema abordado. Neste artigo, analisamos as atividades sobre limites, aplicada com 37 estudantes de uma turma de Cálculo I de uma universidade pública de Santa Catarina. Os dados foram compostos pela ficha de trabalho e pelas intervenções do professor-pesquisador durante a aplicação da proposta. Com os resultados percebemos que a intervenção foi satisfatória para a compreensão dos conceitos abordados e para autonomia de aprendizagem dos estudantes.

Racism as a Workload and Bargaining Issue
Authors: Dhamoon Rita Kaur
Published: February 2020

My main contention is that racism should be read beyond the registers of discrimination, human rights, or harassment – rather, I approach racism as a workload issue that labour organizations and employers need to address at the level of collective bargaining. To illustrate this argument, I focus on racism and workload as it relates to Black faculty, faculty of colour, and Indigenous faculty in universities and colleges in Canada, although the argument can be applied to other job types and other places. While many unions have policies and statements in support of local, national and international anti-racist struggles, the idea of racism as a workload issue has not been seriously taken up by unions/associations, or for that matter by anti-racist activists on university/college campuses. I offer reasons why racism is a workload issue, and consider the potential role of unions in addressing racism.

Authors: Mróz Franciszek
Published: February 2020

This study presents changes in religious tourism in Poland at the beginning of the 21st century. These include the development of a network of pilgrimage centers, the renaissance of medieval pilgrim routes, the unflagging popularity of pilgrimages on foot as well as new forms using bicycles, canoes, skis, scooters, rollerblades and trailskates; along with riding, Nordic walking, running and so on. Related to pilgrimages, there is a growing interest in so-called ‘holidays’ in monasteries, hermitages and retreat homes, as well as a steady increase in weekend religious tourism. Religious tourists and pilgrims are attracted to shrines by mysteries, church fairs and religious festivals, in addition to regular religious services and ceremonies.
Family doctors and residents' knowledge of transsexualism
Authors: Balwiński Michał
Published: February 2020

Problem transseksualizmu jest często traktowany marginalnie zarówno w praktyce lekarskiej, jak i psychologicznej. Skutki takiego postępowania prowadzą do samookaleczeń psychicznych i fizycznych, a także prób i samobójstw pacjentów. Postawione odpowiednio wcześnie rozpoznanie oraz pomoc lekarska mogą w dużej mierze zapobiec tym zjawiskom. Aby jednak było to możliwe, kadra medyczna powinna posiadać odpowiednią wiedzę odnośnie do diagnostyki, leczenia i prowadzenia pacjentów dotkniętych tym schorzeniem. Celem pracy jest próba weryfikacji wiedzy na temat transseksualizmu lekarzy rodzinnych i lekarzy rezydentów. W tym celu poddano analizie 90 prawidłowo wypełnionych ankiet przez tych lekarzy. Pytania w ankiecie zostały skonstruowane pod kątem wiedzy na temat diagnostyki i leczenia transseksualizmu. Otrzymane wyniki pozwoliły na sformułowanie następujących wniosków:
1. Wszyscy ankietowani potwierdzili brak wystarczającej wiedzy na temat transseksualizmu i potrzebę jej pogłębienia.
2. Pojęcia transseksualizmu, transwestytyzmu, transgenderyzmu, crossdressingu były często mylone przez osoby wypełniające ankietę i traktowane błędnie jako synonimy.
3. Istnieje konieczność wczesnej identyfikacji problemu i objęcie tych pacjentów opieką interdyscyplinarnych zespołów.
Distal tarsal joints osteoarthritis: Evidence behind bisphosphonates and NSAIDs to improve lameness
Authors: Dubuc Julia
Published: February 2020

PICO question
In lame horses affected by osteoarthritis of the distal tarsal joints (bone spavin), are bisphosphonates more effective than NSAIDs in long-term alleviation of lameness?
 
Clinical bottom line
Category of research question
Treatment
The number and type of study designs reviewed
Two papers were critically reviewed. There was one field study and a multicentric randomised double-blind placebo control study
Strength of evidence
Weak
Outcomes reported
Each study looked at the effect of either Tiludronate or Firocoxib on alleviation of tarsal lameness. Both Tiludronate and Firocoxib, while administered independently, provided some degree of relief (for up to 120 days) and improved the lameness related to tarsal osteoarthritis.
Conclusion
Since no study was found to directly compare the use of non-steroidal anti-inflammatory drugs and bisphosphonates and that none evaluate the long-term effects of these treatment options on lameness, it is not possible to recommend one treatment option over the other to alleviate lameness caused by tarsal osteoarthritis in horses.
 
How to apply this evidence in practice
The application of evidence into practice should take into account multiple factors, not limited to: individual clinical expertise, patient’s circumstances and owners’ values, country, location or clinic where you work, the individual case in front of you, the availability of therapies and resources.
Knowledge Summaries are a resource to help reinforce or inform decision making. They do not override the responsibility or judgement of the practitioner to do what is best for the animal in their care.
Improving firefly-based multi-objective optimization based on attraction law and crowding distance
Authors: Shayesteh Farid , Kardehi Moghaddam Reihaneh
Published: February 2020

Multi-objective optimization problems are so designed that they simultaneously minimize several objectives functions (which are sometimes contradictory). In most cases, the objectives are in conflict with each other such that optimization of one objective does not lead to the optimization of another ones. Therefore, we should achieve a certain balance of goals to solve these problems, which usually requires the application of an intelligent method. In this regard, use of meta-heuristic algorithms will be associated with resolved problems. In this paper, we propose a new multi-objective firefly optimization method which is designed based on the law of attraction and crowding distance. The proposed methods efficiency has been evaluated by three valid test functions containing convex, nonconvex and multi discontinuous convex Pareto fronts. Simulation results confirm the significant accuracy of proposed method in defining the Pareto front for all three test functions. In addition, the simulation results indicates that proposed algorithm has higher accuracy and greater convergence speed, compared to other well known multi-objective algorithms such as non-dominated sorting genetic algorithm, Bees algorithm, Differential Evolution algorithm and Strong Pareto Evolutionary Algorithm.

Published: February 2020

The exponential distribution is widely used in reliability and life testing analysis. In this paper, two tests of fit for the exponential distribution based on Informational Energy and entropy are constructed. Consistency and other properties of the tests are proved. Using a simulation study, critical values of the proposed tests are obtained and then power values of tests are computed and compared with each other against various alternatives. Finally, we apply the tests for time between failures of secondary reactor pumps and waiting times for fatal plane accidents in the USA from 1983 to 1998.

Weighted Cumulative Residual (Past) Inaccuracy For Minimum (Maximum) of Order Statistics
Authors: Daneshi Safeih , Nezakati Ahmad , Tahmasebi Saeid
Published: February 2020

In this paper, we propose a measure of weighted cumulative residual inaccuracy between survival function of the first-order statistic and parent survival function $\bar{F}$. We also consider weighted cumulative inaccuracy measure between distribution of the last- order statistic and parent distribution $F$. For these concepts, we obtain some reliability properties and characterization results  such as relationships with other functions, bounds, stochastic ordering and effect of linear transformation. Dynamic versions of these weighted measures are considered.
Optimal control of a rectilinear motion of a rocket
Authors: Aliane Mohamed , Moussouni Nacima , Bentobache Mohand
Published: February 2020

In this work, we have modelled the problem of maximizing the velocity of a rocket moving with a rectilinear motion by a linear optimal control problem, where the control represents the action of the pilot on the rocket. In order to solve the obtained model, we applied both analytical and numerical methods. The analytical solution is calculated using the Pontryagin maximum principle while the approximate solution of the problem is found using the shooting method as well as two techniques of discretization: the technique using the Cauchy formula and the one using the Euler formula. In order to compare the different methods, we developed an implementation with MATLAB and presented some simulation results.

Published: February 2020

The 2019 novel coronavirus (2019-nCoV) causes novel coronavirus pneumonia (NCP). Given that approved drug repurposing becomes a common strategy to quickly find antiviral treatments, a collection of FDA-approved drugs can be powerful resources for new anti-NCP indication discoveries. In addition to synthetic compounds, Chinese Patent Drugs (CPD), also play a key role in the treatment of virus related infections diseases in China. Here we compiled major components from 38 CPDs that are commonly used in the respiratory diseases and docked them against two drug targets, ACE2 receptor and viral main protease. According to our docking screening, 10 antiviral components, including hesperidin, saikosaponin A, rutin, corosolic acid, verbascoside, baicalin, glycyrrhizin, mulberroside A, cynaroside, and bilirubin, can directly bind to both host cell target ACE2 receptor and viral target main protease. In combination of the docking results, the natural abundance of the substances, and botanical knowledge, we proposed that artemisinin, rutin, glycyrrhizin, cholic acid, hyodeoxycholic acid, puerarin, oleanic acid, andrographolide, matrine, codeine, morphine, chlorogenic acid, and baicalin (or Yinhuang Injection containing chlorogenic acid and baicalin) might be of value for clinical trials during a 2019-nCov outbreak.

Published: February 2020

Rough volatility models are popularized by \cite{gatheral2018volatility}, where they have shown that the empirical volatility in the financial market is extremely consistent with rough volatility. Fractional Riccati equation as a part of computation for the characteristic function of rough Heston model is not known in explicit form as of now and therefore, we must rely on numerical methods to obtain a solution. In this paper, we give a short introduction to option pricing theory and an overview of the current advancements on the rough Heston model.
Optimal Phase Load Balancing in Low Voltage Distribution Networks Using a Smart Meter Data-Based Algorithm
Authors: Grigoras Gheorghe , Neagu Bogdan-Constantin , Gavrilas Mihai , Tristiu Ion , Bulac Constantin
Published: February 2020

In the electric distribution systems, the “Smart Grid” concept is implemented to encourage energy savings and integration of the innovative technologies, helping the Distribution Network Operators (DNOs) in choosing the investment plans which to lead the optimal operation of the networks and increasing the energy efficiency. In this context, a new phase load balancing algorithm was proposed to be implemented in the low voltage distribution networks with hybrid structures of the consumption points (switchable and non-switchable consumers). It can work in both operation modes (on-line and off-line), uploading information from different databases of the DNO which contain: the consumers’ characteristics, the real loads of the consumers integrated into the Smart Metering System (SMS), and the typical load profiles for the consumers non-integrated in the SMS. The algorithm was tested in a real network, having a hybrid structure of the consumption points, on a time interval by 24 hours. The obtained results were analyzed and compared with other algorithms from the heuristic (Minimum Count of Loads Adjustment algorithm) and the metaheuristic (Particle Swarm Optimization and Genetic Algorithms) categories. The best performances were provided by the proposed algorithm, such that the unbalance coefficient resulted in the smallest value (1.0017). The phase load balancing led to the following technical effects: decreasing the average current in the neutral conductor with 94% and for the energy losses with 61.75 %, and increasing the minimum value of the phase voltage at the farthest pillar with the 7.14 %, compared to the unbalanced case.
Unilateral Cleavage Furrows in Multinucleate Cells
Authors: Bindl Julia , Molnar Eszter Sarolta , Ecke Mary , Prassler Jana , Müller-Taubenberger Annette , Gerisch Günther
Published: February 2020

Multinucleate cells can be produced in Dictyostelium by electric-pulse induced fusion. In these cells unilateral cleavage furrows are formed at spaces between areas that are controlled by aster microtubules. A peculiarity of unilateral cleavage furrows is their propensity to join laterally with other furrows into rings to form constrictions. This means, cytokinesis is biphasic in multinucleate cells, the final abscission of daughter cells being independent of the initial direction of furrow progression. Myosin-II and the actin-filament cross-linking protein cortexillin accumulate in the unilateral furrows, as they do in the normal cleavage furrows of mononucleate cells. Myosin-II is not essential for cytokinesis, but stabilizes and confines the position of the cleavage furrows.
Serverless GEO Labels for the Semantic Sensor Web
Authors: Graupner Anika , Nüst Daniel
Published: February 2020

As the amount of sensor data made available online increases, it becomes more difficult for users to identify useful datasets. Semantic web technologies improve discovery with meaningful ontologies, but the decision of suitability remains with the users. The GEO label provides a visual summary of the standardised metadata to aid users in this process. This work presents novel rules for deriving the information for the GEO label's multiple facets, such as user feedback or quality information, based on the Semantic Sensor Network Ontology and related ontologies. It enhances an existing implementation of the GEO label API to generate labels for resources of the Semantic Sensor Web. The prototype is deployed to serverless cloud infrastructures. We find that serverless GEO label generation is capable of handling two evaluation scenarios for concurrent users and burst generation. More real-world semantic sensor descriptions and an integration into large scale discovery platforms are needed to develop the presented solutions further.
Instability of Nucleic Acids in Airborne Microorganisms under Far Infrared Radiation
Authors: Huang Wei-Hong , Li En-Jing
Published: February 2020

Emergence of zoonotic-human pathogens is proven to be a lethal threat to public health, and RNA virus including influenza viruses, severe acute respiratory syndrome coronavirus, middle east respiratory syndrome coronavirus, Wuhan coronavirus (COVID-19), plays a pivotal role. As those viruses as airborne microorganisms spread mainly by tiny airborne particles, it is important to de-active those airborne particles before their entry into human bodies. In this study, we investigated the effect of far infrared (FIR) radiation on inhibition of airborne microorganisms. The result confirmed that double stand DNA from airborne microorganisms were stable under mild FIR radiation. However, single strand RNA from them was found to be sensitive to FIR radiation, indicating that RNA virus in airborne particles is instable under FIR radiation. Based on this observation, two models on usage of FIR radiation to prevent RNA virus transmission and cure RNA virus infection were proposed, implying that FIR radiation might be a cheap, convenient, and efficient method in clinic to treat RNA virus.

Published: February 2020

Interest in drone solutions in forestry applications is growing. Using drones, datasets can be captured flexibly and at high spatial and temporal resolutions when needed. In forestry applications, fundamental tasks include the detection of individual trees, tree species classification, bio-mass estimation, etc. Deep Neural Networks (DNN) have shown superior results when comparing with conventional machine learning methods such as Multi-Layer Perceptron (MLP) in cases of huge input data. The objective of this research was to investigate 3D convolutional neural networks (3D-CNN) to classify three major tree species in a boreal forest: pine, spruce, and birch. The proposed 3D-CNN models were employed to classify tree species in a test site in Finland. The classifiers were trained with a dataset of 3039 manually labelled trees. Then the accuracies were assessed by employing independent datasets of 803 records. To find the most efficient set of feature combination, we compare the performances of 3D-CNN models trained with hyperspectral (HS) channels, RGB channels, and canopy height model (CHM), separately and combined. It is demonstrated that the proposed 3D-CNN model with RGB and HS layers produces the highest classification accuracy. The producer accuracy of the best 3D-CNN classifier on the test dataset were 99.6%, 94.8%, and 97.4% for pines, spruces, and birches, respectively. The best 3D-CNN classifier produced ~5% better classification accuracy than the MLP with all layers. Our results suggest that the proposed method provides excellent classification results with acceptable performance metrics for HS datasets. Our results show that pine class was detectable in most layers. Spruce was most detectable in RGB data, while birch was most detectable in the HS layers. Furthermore, the RGB datasets provide acceptable results for many low-accuracy applications.
Suppress Numerical Oscillations in Transient Mixed Flow Simulations with a Modified HLL Solver
Authors: Mao Zhonghao , Guan Guanghua , Yang Zhonghua
Published: February 2020

Transition between free-surface and pressurized flows is an crucial phenomenon in many hydraulic systems, including water distribution systems, urban drainage systems, etc. During the transition, the force exerted on the structures changes drastically, thus it is meaningful to simulate this process. However, severe numerical oscillations are widely observed behind filling-bores, causing unphysical pressure variations and even computation failure. In this paper, some oscillation-suppressing approaches are reviewed and evaluated on a benchmark model. Then a new oscillation-suppressing approach is proposed to admit numerical viscosity when the water surface is at proximity of conduct roof which has first order accuracy. This approach adds numerical viscosity when water surface is at the proximity of conduct roof. It can sufficiently suppress numerical oscillations under an acoustic wave speed of 1000m/s and is simple to apply. In comparison with two experiments, the simulation results of this method show good agreement and little numerical oscillations. The results in this paper can help readers to choose an appropriate oscillation-suppressing method to improve the robustness and accuracy of flow regime transition simulations.

Salmonella, especially invasive non-typhoidal Salmonella (iNTS) are responsible for developing various invasive diseases, and possess higher mortality rate, due to their higher antibiotic resistance profile than the other bacteria. Therefore, the present study was concerned to develop epitope based peptide vaccine against iNTS species as a successive and substitute protective measures. The study considered comprehensive Immunoinformatic approaches, followed by molecular docking and molecular dynamics simulation to predict the efficient vaccine candidate T cell and B cell epitopes, based on the outer membrane proteins. The study identified two best epitopes YGIFAITAL and KVLYGIFAI from total iNTS outer membrane proteins, which showed higher immunity, non-allergenicity, non-toxicity and also showed higher conservancy and population coverage values. Both epitopes showed higher binding affinity and stability towards HLA-C* 03:03. The MM-PBSA binding free energy showed the YGIFAITAL epitope binds more tightly with both MHC-I and MHC-II molecules. The total contact, H-bond analysis and RMSF results also validate the efficiency of these epitopes as vaccine candidate. The projected B cell epitopes AAPVQVGEAAGS, TGGGDGSNT and TGGGDGSNTGTTTT showed higher antigenicity. Overall, the study concluded that these epitopes can be considered as the potential vaccine candidate to make a successive vaccine against iNTS species. However, this result further needs to be validate by wet lab research to make successive vaccine with these projected epitopes.

Bu çalışma kapsamında dışsal motivasyon, içsel motivasyon ve performans arasındaki ilişkiler ele alınmıştır. Çalışmada öncelikle dışsal motivasyon ve içsel motivasyon kavramları ele alınmıştır. Dışsal ve içsel motivasyon faktörlerine yer verilmiştir. Motivasyon kuramları ile dışsal ve içsel motivasyon kuramlarla anlatılmaya çalışılmıştır. Performans kavramı ve performans boyutlarından (görev performansı ve bağlamsal performans) bahsedilmiştir. Performans artışında dışsal ve içsel motivasyon faktörlerinin önemli olduğu görülmektedir. Konu ile ilgili önceki çalışmalar da bunu göstermektedir. Ancak bu çalışmada dışsal ve içsel motivasyon ile performans etkileşimi kuramlarla ele alınmıştır. Dışsal motivasyonun, içsel motivasyonu ve performansı pozitif yönde etkilediği kuramsal bakış açısıyla incelenmiştir.Yine benzer bakış açısıyla içsel motivasyonun da performansı pozitif yönde etkilediği belirlenmiştir. Ayrıca dışsal motivasyonun performansı hem doğrudan artıracağı hem de içsel motivasyon aracılığıyla artıracağı ortaya konulmuştur. Literatürde benzer çalışma sayısının az olması araştırmayı değerli hale getirmektedir.
Striking Differences in Physical and Mental/Behavioral Health Status Between Homeless Bisexual and Gay Young Men in New York City, United States
Authors: Gunness Harlem J.

Although many studies have been conducted on Human Immunodeficiency Virus (HIV) infection and treatment among homeless bisexual and gay young men, few have focussed on their overall health status. This study was conducted as a comparative assessment of self-reported physical and mental health status between homeless bisexual and gay young adult men in New York City, United States. Face-to-face interviews were conducted with a purposive sample of 30 subjects in a homeless drop-in program. Bisexual men reported more physical and mental/behavioral health concerns than gay men. More large-scale research is needed to understand how bisexual men accessed healthcare as compared to gay men.
Effect of Dip on Five-Spot Sweep Pattern

Distortions caused by dip on five-spot sweep pattern were determined by visual experiments on a model composed of parallel plates of glass with holes drilled at the well positions. This model was designed to simulate a reservoir depleted of its primary oil and containing a gas phase. Prior to interference, it was found that the injected fluid took a nearly circular shape about the injection well for the cases studied. However, these circles moved downdip considerably under the influence of gravity. It was concluded that pattern flooding should be practical for many dipping reservoirs. A quantitative measure is given of how much the well position should be altered to allow for dip. Experimental determinations of injectivity showed this to be about the same in a dipping reservoir as in a horizontal one.

Introduction

This investigation was undertaken at the suggestion of the Pacific Coast area, Shell Oil Co., where a pilot water flood in a dipping reservoir was being carried out at the time this paper was in preparation. Prior to the undertaking of this flood there had been considerable speculation as to how gravity would distort a flood pattern in a dipping reservoir. The thought was expressed in some quarters that a five-spot flood would not be applicable to a dipping reservoir because the flood pattern would elongate in the direction of dip and would never form a "seal" around each five-spot. If the flood pattern elongated sufficiently, both the oil and the water might flow largely downdip rather than into the pattern producers. In view of the importance of the California water floods, it was deemed important to determine the effects of gravity on a five-spot pattern in a dipping reservoir.

Previous work had also been carried out in this laboratory, but only for the single-fluid case. The present investigation extends these results to multifluid cases. Several sets of pictures of flood fronts are presented so that the process can be visualized. From these pictures, curves are obtained which show the correct drilling position for achieving equal times of oil-bank breakthrough. Several injectivity curves are also presented which may aid in prediction of injection rate.

The production history of a gas-cap-drive reservoir was reproduced by calculations, and predictions were made for operations under primary depletion, pressure maintenance by gas injection, and pressure maintenance by water injection. Although the general equations used in this analysis have been available to the industry for a number of years, the procedure has not had extensive use because of the unusually large time requirements for developing numerical results. The use of digital computing equipment for processing the calculation work generally reduced the time usually required for an extensive analysis of this type. Calculation techniques were developed that were equally applicable for solving the gas-cap-drive problem, whether digital computing equipment or desk calculators are used. These techniques are outlined and the procedures are illustrated by the field problem.

Introduction

The analysis of a gas-cap-drive reservoir requires the simultaneous solution of the volumetric balance and displacement equations. Equations for the analysis of combination drive reservoirs were presented by Wooddy and Moscrip in a previous paper: These equations permit the evaluation of possible operating processes in order that the optimum method of producing the reservoir may be determined. Although these equations represent the basic technique known for the detailed analysis of gas-cap-drive reservoirs, the calculation processes are quite complex and time consuming; hence, the procedure has not had extensive use.

Recently, these equations were satisfactorily applied with the aid of a digital computer to investigate the completion history of a gas-cap-drive reservoir under the following operating methods: primary depletion, depletion under full pressure maintenance by gas injection, and depletion under full pressure maintenance by water injection. The use of digital computing equipment substantially reduced the time necessary for making the computations and permitted a more concise investigation of the reservoir's depletion history than was possible when the desk calculator was used. This more rigorous investigation also permitted a detailed analysis of the calculation procedures necessary in the solution of the gas-cap-drive problem. This paper outlines the procedure of analyzing a gas-cap-drive reservoir and illustrates the process with an actual field problem.
Factors Affecting Well Productivity - II. Drilling Fluid Particle Invasion into Porous Media

The phenomenon of drilling mud particle invasion into consolidated porous media is discussed. The data and results are presented in two parts:a study of the ability of a mud containing sized particles to bridge and initiate filter cake formation on or in consolidated porous media, anda study of the degree and extent of reduction of the effective oil permeability of porous media by mud invasion.

This study has shown thatbridging of pores by particles is required to initiate filter cake formation,a filter cake may be formed inside the pores of the invaded zone of the porous sample, andmud particles invade porous media of the type studied to a depth of at least 1 to 3 cm and cause substantial "permanent" reduction in effective oil permeability.

Introduction

The first paper in this series described filtration characteristics of drilling muds and presented data on the surge phenomenon. It was shown that a reduction in permeability of the samples used resulted from exposure to the mud. The most plausible reason for a loss in permeability was the invasion of solid particles into the pores of the porous medium resulting in plugging of these pores.

Several authors have pointed out that a loss of permeability of a sample occurs after exposure to muds. The particle invasion phenomenon was usually deduced, as in the first of this series of papers, from a loss in permeability of the sample after such exposure. Nowak and Krueger observed a cloudy filtrate coming from the Alundum samples used in their experiments. Electron micrographs of the solids contained in these filtrates provided good evidence of particle invasion into and through a porous medium, and certainly indicated that other mud particles probably invaded and remained in the pores.

It has been suggested that mud particle bridging of pore entries (either internal or external, or both) occurred during the surge period of an experiment wherein a consolidated porous medium was exposed to a mud under a pressure differential.
