usos de processos materiais acadêmicos em artigos científicos
Authors: Miranda Monique Vieira
Published: March 2022

Esta pesquisa teve como objetivo analisar os processos materiais acadêmicos mais frequentes em um corpus de artigos científicos, com base na Linguística Sistêmico-Funcional (LSF), principalmente Halliday e Matthiessen (2014). Para tanto, foi utilizado o Corpus Acadêmico do Português Brasileiro (CAPB), representativo do gênero em questão, com aproximadamente 12,3 milhões de palavras, a fim de observar possíveis diferenças e semelhanças no uso dos processos materiais em diferentes áreas do conhecimento. Para a análise, foram selecionadas amostras dos processos materiais mais frequentes do corpus. Segundo pesquisa realizada por Miranda (2021), dentre os dez verbos acadêmicos mais frequentes, seis realizaram orações materiais, sendo eles: apresentar, utilizar, realizar, encontrar, analisar e determinar. Nesta pesquisa, esses verbos foram estudados em suas realizações enquanto orações materiais, levando em consideração a área de conhecimento em que ocorreram, assim como seus usos e implicações dentro do texto. Observou-se que os processos materiais foram empregados similarmente ao longo das diferentes áreas do conhecimento com a finalidade de descrever e relatar experimentos, análises, recomendações e contribuições dos autores. Entretanto, por meio do estudo contrastivo entre as áreas de conhecimento, notou-se que a diferença entre elas estava na forma como optaram empregar os processos materiais e, desse modo, nas implicações textuais ocasionadas por tal escolha. Por fim, conclui-se que a análise dos resultados encontrados contribui para uma compreensão mais aprofundada sobre a escrita acadêmica, avançando os estudos teóricos em língua portuguesa baseados na LSF.

Objective: This research was carried out to determine the university students’ views and attitudes on sexual myths/rape myths.
Methods: The sample consisted of 140 students studying at the faculty of engineering-architecture, the faculty of science and literature, and the school of health sciences. Data collection tools consist of two parts. In the first part, there are questions about sociodemographic characteristics and sexuality. In the second part, there are 15 myths about sexual myths and sexual assault myths created by researchers with the aid of literature.
Results: 32,1% (n=45) of them are in the nursing department of SBYO, 25,7% (n=36) in the departments of the engineering-architecture faculty, 42,1% (n=59) in the departments of the faculty of science and literature. It was observed that the students received the most information about sexuality from communication tools (44,2%), and 48,6% (n=68) had negative thoughts about sexual intercourse before marriage. It was concluded that men, nursing and engineering-architecture faculty students and those who had a negative opinion about sexual intercourse before marriage were significantly more likely to agree with some sexual myths/sexual assault myths.
Conclusion: There are those who accept these myths as true, albeit at a low rate, among university students. This may be due to gender roles, restrictive cultural norms, and the inadequacy of education and information on sexual assault and sexuality in the education system. Shaping the education system will provide university students’ awareness about sexual myths and sexual assault myths, and will help students acquire and internalize correct information.
La función estatutaria de delimitación del territorio autonómico y la integración de comunidades autónomas
Authors: González García Ignacio
Published: March 2022

Ante la falta de regulación constitucional expresa sobre el régimen de las posibles alteraciones territoriales del mapa autonómico, la doctrina mayoritaria, apoyada fundamentalmente en la STC 99/1986, ha venido defendiendo una interpretación muy amplia de la remisión que el art. 147.2.b de la Constitución hace a los estatutos de autonomía para realizar la delimitación del territorio autonómico. En este trabajo se justifica por qué esa habilitación a los estatutos no es suficiente para que, a través de la reforma de los mismos, se lleve a cabo la creación de una nueva comunidad autónoma a partir de la integración de otras preexistentes.
El general Franco, ante los reporteros extranjeros. La Oficina de Información Diplomática y las entrevistas al dictador (1958-1968)
Authors: Diego González Álvaro de
Published: March 2022

Adolfo Martín-Gamero, director de la Oficina de Información Diplomática, tramitó las entrevistas que Franco celebró con periodistas de la prensa internacional entre 1958 y 1968. Basándose en documentación inédita de la Real Academia de la Historia, este estudio analiza el contexto y contenido de aquellos encuentros periodísticos insertos en la estrategia propagandística de la dictadura y en los que, además, el diplomático actuó como intérprete. El examen revela la importancia que el franquismo atribuía a las grandes cabeceras estadounidenses (The New York Times, en especial), debido a su influencia en la opinión pública de su principal aliado internacional, y a Le Figaro para estrechar relaciones comerciales con Francia y facilitar el acceso de España al Mercado Común.

La Operación Propaganda Exterior (OPE, 1958-‍1961) fue una operación de propaganda secreta del franquismo intermedio orientada a mejorar la imagen del régimen en el exterior, principalmente en EE. UU., ante el contexto previo de bloqueo internacional de España como antiguo aliado fascista y como dictadura. También se orientó a vigilar y moldear la opinión pública española recurriendo a los modernos métodos de propaganda política. Este artículo analiza el contexto histórico-ideológico previo de la OPE, así como su naturaleza, protagonistas y desarrollo en sus ámbitos principales: información, cultura y cine. Su principal logro fueron los largometrajes proespañoles de Bronston.
Structural-parametric synthesis of the model of multi-criteria optimization of the solution of training problems with an aviation multifunctional simulator
Authors: Mistrov L.Е. , Shepovalov E.М.
Published: March 2022

The basis for the training of aircraft crews is the solution of a finite set of training tasks modeled using aviation multifunction simulators (AMT). To develop a model of multi-criteria choice of solutions for an individual and the entire set of educational tasks, its structural and parametric synthesis is carried out on the basis of the optimal distribution of AMT hardware and software resource for modeling various factors and conditions of information processes during educational tasks. Their solution is based on the search for optimal options on the set of branching and / or repeating information flows in the form of a set of elementary operations on the set of performance criteria, taking into account the principles and preferences of instructors - decision makers. The choice of a solution is carried out by summarizing single-criteria schemes for solving a particular educational problem using the Bellman principle and building on their basis a model of multi-criteria selection (MVR). The basis of the generalized MVR is the representation of AMT in the form of a directed graph in which the vertices characterize the learning tasks, and the arcs determine the possible solutions to them in the form of a certain set of elementary operations with optimal weight vectors connecting the initial and final vertices. The essence of the model is the sequential combination of the paths of elementary operations taking into account the integrity of the presentation of the educational task and the narrowing of their number through the selection function implemented using the dominance and blocking algorithms in the binary relation, which has the property of transitivity and asymmetry. The choice of a generalized solution is carried out on the basis of Pareto optimal solutions, constructed by extrapolation of expert estimates of decision-makers on a cone of preferences for various situations related to computer computing capabilities. The generalized solution of the MVR substantiation problem is based on the selection of optimal routing routes for elementary operations on the set of multidisciplinary training tasks solved by AMT.

Published: March 2022

Proper finishing and polishing have become the indispensable step in clinical restorative dentistry due to increased aesthetic demands. There are several polishing systems containing fine particle size abrasives. The adhesion of bacterial plaque to restoration depends on the surface properties and composition of materials. In literature, surface roughness after polishing is well documented, but the timing, i.e., immediate or delayed polishing affecting the bacterial adherence and microhardness on the composite needs research. As the Streptococcus mutans has a major role in primary and secondary caries, so in this light, this study is conducted to investigate the best timing of polishing affecting the bacterial adhesion and microhardness of composite resin.

: To evaluate the Streptococcal mutans adhesion and microhardness of composite resin after polishing them, immediately and after 24 hours of curing.

: Sixty specimens were made from composite resin Filtek Z 350 XT (3M ESPE) of 6mm diameter and 4mm height, was cured by placing a Mylar strip and divided into 3 groups- Group 1 the control group with only MYLAR-STRIP, Group 2- Polishing system SOF-LEX (3M ESPE Dental products St. Paul, MN,USA.) Group 3- Polishing with SUPER-SNAP (Shofu Inc., Kyoto, Japan). Group 2 and 3 were further divided into two subgroups according to the polishing time- immediate and delayed. The Streptococcal mutans adhesion for each group was measured by colony forming units and compared. The mean log of CFU/mL present in the biofilm was also calculated.

The results of bacterial adherence was analysed by three-way ANOVA (analysis of variance) (p<0.01) and the ANOVA two-way of variance was used for checking microhardness (p<0.01). A p value <0.01 was considered to indicate a statistically significant for both bacterial adhesion and hardness.

Polishing after 24 hours of curing showed less bacterial adherence on the composite surface, regardless of the polishing treatment performed(p<0.01). Polishing with SOF-LEX(Group-2) had the lower bacterial adherence than SUPER-SNAP (Group-3), Control group (Mylar matrix strip) promoted the lowest bacterial adhesion on the surface composites. Micro hardness of composite was lowest in Mylar matrix group. Immediate polishing procedure showed lower microhardness values as compared to polishing that was delayed for 24hours for both polishing groups.

SOF-LEX system can be used for chairside polishing of composite restorations in clinic and delayed finishing and polishing of composite shows better surface microhardness values.

Published: March 2022

Mandibular ridge resorption is a biomechanical and a complex disease that brings about chronic, progressive, cumulative and irreversible changes in bone structure resulting in severe impairment in fit and function of prosthesis. Some common hormonal, neurological, metabolic disorders can affect the adaptability of denture which can be diagnosed by a trained prosthodontist with proper history taking and clinical examination. If a denture stays inside or outside of the neutral zone, it will be unstable during functional & physiological activities such as talking, swallowing and mastication. Neutral zone technique is a long being used for the management of severely resorbed mandibular ridge. Various materials can used in recording neutral zone which have their own advantages and disadvantages. This technique serves as an alternative approach for the construction of mandibular complete denture. This technique is most effective for denture where there is a highly atrophic ridge, neuromuscular incoordination and history of denture instability. This clinical report describes in detail the fabrication of a complete denture in a patient with poorly formed mandibular ridge using neutral zone technique with addition of cast metal in mandibular denture for extra stability.

Authors: Prakash Poonam , Gupta Richa
Published: March 2022

: To evaluate and compare the effect of two approaches of cryotherapy for improving the success rate of Inferior alveolar nerve block and reduction of pain during access opening in mandibular molars with symptomatic irreversible pulpitis.

: Thirty patients diagnosed with symptomatic irreversible pulpitis were selected based on inclusion and exclusion criteria to participate in the study. 3 groups were designed; Group 1(Control group) - inferior alveolar nerve block(IANB) with lignocaine (2%) adrenaline (1:80000), Group 2(IANB+ small ice pack)-inferior alveolar nerve block with lignocaine (2%) adrenaline (1:80000) + small ice packs (wrapped in sterile gauze); Group 3 (IANB+Endo Ice) -inferior alveolar nerve block with lignocaine (2%) adrenaline (1:80000) + Endo Ice application. Patients were randomly allocated to any one of the groups: The level of preoperative pain was recorded using the Numeric visual analogue scale (VAS). Endodontic therapy was done 15 minutes after the IANB injection. The level of intra operative pain during access opening was recorded again using the same scale. If the patients reported moderate or severe pain during the procedure, the IANB was defined as “unsuccessful,” and a supplementary injection was administered.

: There was statistically significant difference found in pain reduction among 3 groups (p=0.01). Post hoc analysis revealed significant difference between Group 1(Control) and Group 2(IANB+ small ice pack) with (p=0.003). Overall success rate of IANB was found to be 66.66 %.

: Both the techniques of intraoral cryotherapy exhibited improved pain reduction as well as increased the success rate of IANBs in mandibular molar teeth with SIP. Hence based on the results obtained, it is suggested that cryotherapy can serve as a useful adjunct to anaesthesia during endodontic procedures.

Published: March 2022

Glaucoma is a chronic multifactorial degenerative optic neuropathy and is the second leading cause of irreversible blindness worldwide. Aim of this study was to study trabeculectomy with collagen implant versus trabeculectomy with mitomycin C in patients requiring glaucoma surgery

50 eyes of 44 patients were assigned randomly to undergo trabeculectomy either with collagen implant (study group) or with MMC (mitomycin C)(control group). Preoperative data included age, gender, IOP (intraocular pressure) and number of preoperative medications. Postoperatively IOP, number of glaucoma medications and postoperative complications if any were recorded on follow up at seven days, one month and three months. Proportion was compared using chi square test while mean using student t test.

Baseline characteristics were matched. The intervention arm had lower IOP post operatively at 3 months (11.84±4.21 vs 17.72±5.93, p = 0.002) but not at day 7 (17.14±9.88 vs 21.37±11.07, p=0.12), 1 month (16.77±11.54 vs 22.91±9.62 p = 0.05); lesser need of anti-glaucoma medication (0.48±0.77 vs 1.95±1.26 p = 0.0001); more complete treatment success (15 vs 7), lower treatment failure (1 vs 4), less Postoperative complications were seen in cases than controls, flat AC(12%vs16%), Hyphema (4% vs 8%); However hypotony were comparable(12%).

This study supports superiority of collagen implant with trabeculectomy as opposed to trabeculectomy with mitomycin C in terms of better clinical outcome and reduced post operative antiglaucoma medications.

Published: March 2022

This study aimed to determine the effectiveness of treatment by laser or Intravitreal anti VEGF- Bevacizumab (IVB) or combined therapy (both laser and anti-VEGF) in diabetic macular edema (DME).

A prospective observational study in which 90 eyes with diabetic macular edema (DME) were enrolled. According to patient compliance, they were divided in to 3 groups where there was 30 eyes in each group. Patients with DME who were treated with laser were observed (group A). Patients with DME who were treated with Intravitreal Bevacizuamb (IVB) were observed (group B).Patients with DME who were treated with both IVB and Laser were observed (group C). All patients underwent complete ophthalmic examination at baseline and at one and three months after treatment. The outcome measures were changes in Central macular thickness(CMT) and best corrected visual acuity(BCVA). A P value less than 0.05 considered statistically significant.

One month after treatment, Group B showed more statistically significant reduction in CMT and improvement in BCVA than group A and group C(P<0.05). Three months after treatment, group C showed more statistically significant reduction in CMT and improvement in BCVA when compared to other two groups(P<0.05).

Combined therapy with IVB and laser appeared to be superior to Laser alone or IVB alone in reducing macular thickness and improving visual acuity. Thus combined therapy can be considered as most effective treatment in DME.

Authors: Mohammed Rizana V , Sujithra H  , Pillai Gopal S , Greeshma C R
Published: March 2022

: The concept of retrograde axonal degeneration is well studied for visual pathway lesions upto lateral geniculate body. Since clinically evident optic nerve head changes and papillary changes are usually absent in post geniculate lesions, very few studies have been reported to look for the presence of retrograde axonal degeneration in these lesions.

To analyse RNFL and GCC thickness in patients with retrogeniculate lesions using Spectral Domain OCT and to determine any characteristic thinning pattern corresponding to the visual field defect.

: Patients attending Ophthalmology OPD as diagnosed cases of unilateral retrochiasmal lesions were included in the study. Those who showed homonymous hemianopia corresponding to the retrochiasmal lesions were subjected to OCT RNFL and GCC. Spectral domain OCT was performed on all patients using ZEISS Cirrus HD-OCT Model 400.

: Mean age of the study population was 55.5±14.02 years. 21(70%) patients were males, 9(30%) were females. Ipsilateral eyes have superior RNFL thinning, contralateral eyes have inferior, nasal and temporal quadrants thinning. Average RNFL thickness and GCC thickness was reduced in the contralateral eyes. In ipsilateral eyes, temporal GCC was thinner compared to nasal, whereas in contralateral eyes, nasal GCC was thinner compared to temporal.

: The pattern of RNFL and GCC thinning corresponds with pattern of visual field loss. The thinning of RNFL and GCC is in accordance to the known trajectories of the crossed and uncrossed projections arising in the nasal and temporal hemiretinae respectively. Our study substantiates that retrograde axonal degeneration occurs in post geniculate lesions also.

Published: March 2022

Diabetes mellitus is a leading cause of blindness worldwide. The disease affects the generalized micro and macro vasculature of various structures. Retina, kidney and peripheral nerves are the major sites of micro vasculature involvement. Our study aims to find the correlation between diabetic retinopathy (DR) and diabetic nephropathy.

This non-randomized, prospective study was conducted at a tertiary care hospital in South India between November 2014 and May 2016. Study included 100 patients with diabetic nephropathy referred for fundoscopy from the nephrourology department, excluding those with hazy media enough to interfere with a detailed fundus examination and management. All subjects underwent complete ocular examination and systemic evaluation after obtaining informed consent. Visual acuity, fundoscopy by direct and indirect ophthalmoscope, fundus photography and optical coherence tomography were done as and when required. Blood investigations like fasting blood sugar, post prandial blood sugar, glycosylated haemoglobin, haemoglobin levels, serum creatinine and blood urea nitrogen, lipid profile, urine routine and 24-Hour urine albumin were recorded. DR was classified according to ETDRS classification and different grades were compared with grades of nephropathy and association was analysed statistically.

: There was significant association between fundal changes and albumin excretion in urine. Among subjects with massive albuminuria, 64.7% of them had proliferative DR (PDR). Among subjects with moderate albuminuria, majority had Moderate NPDR and subjects with microalbuminuria majority had normal fundus. There was a positive correlation between DR and total cholesterol.

The severity of DR correlates with severity of diabetic nephropathy.

Published: March 2022

Aesthetics is an integral part of orthodontics, and color is an important aspect of aesthetics. Hue, value, and chroma are the three objective variables used to describe color. The tooth color exhibits a large variation influenced by the structure of enamel and dentin. Enamel colour alterations may derive from the irreversible penetration of resin tags into the enamel structure at depths reaching 50 µm.

Natural Teeth: A total of 80 extracted premolar teeth were collected and then washed thoroughly with plain water and stored in normal saline to prevent them from drying up.Eighty human premolar teeth that had been previously extracted from orthodontic patients.All the teeth selected were cleansed by using a rubber cup and pumice slurry for 20 seconds on a slow speed contra angle hand piece (10,000 rpm), rinsed thoroughly with saline for 10 seconds and air-dried with gentle jets of oil-free compressed air.

In this study shows the frequency distributions of color difference ΔE at various time points in Transbond XT group. The mean difference before treatment and debonding and finishing (ΔE1) was 0.91± 0.43, mean difference before treatment and photogeing (ΔE2) was 1.49±0.85 and mean difference after debonding and finishing and photoageing (ΔE3) was 0.81±0.51. The frequency distributions of ΔE at various time points in Ormco group. The mean difference before treatment and debonding and finishing (ΔE1) was 0.72±0.24, mean difference before treatment and photogeing (ΔE2) was 1.88±0.83 and mean difference after debonding and finishing and photoageing (ΔE3) was 0.97±0.55.

Ormco Enlight showed highest enamel color change of ΔE2 value 2.92 after debonding & finishing. Rely A bond showed least enamel color change of ΔE2 value 2.80. Of all the groups studied there is a significant color change in the enamel but less than the minimum threshold value of ΔE 3.7 units.

Authors: Manasawala Taher , Batni Sushmita , Mujumdar Devashree
Published: March 2022

Treatment of a malocclusion characterized by open bite can be a difficult task for the orthodontist because such a malocclusion develops as a result of the interplay of many different etiologic factors. This article presents a case series of patients showing varying degrees of anterior open bite having a tongue thrusting habit. All patients were given a tongue crib appliance along with 0.022MBT preadjusted edgewise brackets treated with different modalities. Extraction of all 1st premolars was initiated in one case and retraction of anterior teeth was done using skeletal anchorage to improve the overjet and overbite. In other cases, non-extraction therapy was advocated with a modification of MEAW technique by incorporating reverse arch wire mechanics and correcting the anterior open bite.

Published: March 2022

Due to the fact that osseointegration is contingent on bone metabolism, low vitamin D levels in the blood may have an unfavourable impact on bone development around dental implants. Only a few researches have looked into the probable link between vitamin D levels in the blood and early dental implant failure (EDIF), which happens within three months of placement well before the prosthetic abutment is engaged. The goal of this study was to see if there is a association between low vitamin D levels in the blood and EDIF.

This prospective study was conducted among the total of 100 patients within the age group 18-55 years who fulfilled the inclusion & exclusion criteria of the study. These subjects were selected from the patients who visited the outpatient department of Himachal Dental College, Sundernagar. Clinical parameters were assessed at 3 month post-operatively and implant failures were assessed and correlated with the levels of serum vitamin D.

In our study, 6, 71 and 23 subjects were <10 ng/ml, 10-30 ng/ml and >30 ng/ml vitamin D serum levels respectively. One (1) incidence of failure was reported in patients with high serum levels of vitamin D (>30 ng/mL) (4.3%). Failed implants were revealed maximum among subjects with vitamin D level <10 ng/ml (16.67%), followed by 10-30 ng/ml (7.04%).

The relation between serum Vitamin D levels and early dental implant failure is statistically insignificant. More clinical trials with a prospective design and appropriate statistical analysis are needed, to confirm whether or not a relation between low serum levels of vitamin D and an increased rate of early dental implant failure exists.

Published: March 2022

Compromised teeth are challenging to the dentist which complicate the treatment plan and affects the long-term prognosis. Advances in dentistry, as well as the increased desire of patients to maintain their natural dentition, have led to treatment and preservation of teeth that once would have been removed. The most commonly extracted teeth due to dental caries and periodontal disease are mandibular molars. These teeth are the major standpoint for occlusion, and also have a wide pericemental area. Root resection is the treatment option for preserving molars with furcation involvement. It is the process by which one or more of the roots of teeth are removed at the level of furcation while leaving the crown and remaining roots in function. The procedure of root amputation was first introduced by Farrar in 1884. It is a suitable treatment option when the resorption, perforation, or periodontal damage is restricted to one root while the other root is relatively healthy. This case report describes, root amputation as a successful treatment method to save a mandibular first molar which would have been extracted.

Thermal Environment Simulation and Safety Prewarning of Hot Mines Based on Big Data
Authors: Su Peihua
Published: March 2022

In deep mines, thermal disasters pose a serious threat to the health and production efficiency of underground workers. It is of certain safety and economic significance to numerically simulate the thermal environment of hot mines. The existing studies are limited in that they only consider a single air flow velocity field or thermal field, or a single heat source. To overcome the limitation, this paper collects the big data on the temperature and humidity of smart coalmines, and numerically simulates the thermal environment in hot mines. Firstly, the authors analyzed the heat sources, including relative heat sources like the hot surrounding rock and hot water, and absolute heat sources like electromechanical equipment, chemical reactions, and the self-compression of the airflow. Next, the thermal environment of the hot mine was simulated by the Lattice Boltzmann method, and the flow state of the hot fluid in the roadways was analyzed in details. The proposed numerical simulation approach was proved effective through experiments, providing a reference for the safety prewarning of hot mines.
Thermal Stress Analysis and Structural Optimization of High-Rise Buildings under Stack Effect
Authors: Huang Cheng , Chen Juan
Published: March 2022

Thermal stress and thermal strain are the major causes of wall cracking of high-rise buildings. The key to wall cracking control lies in regulating thermal stress, and reducing the uncoordinated deformation probability of structural members. However, the existing studies have not considered the common stack effect of high-rise buildings. To fill up the gap, this paper analyzes the thermal stress and optimizes the structure of high-rise buildings under stack effect. Firstly, the cracking mechanism of structural members in high-rise buildings was expounded under stack effect, and the thermal stress of these buildings was analyzed in the light of that effect. Next, finite-element calculation was performed on the instantaneous stress field of high-rise buildings. After that, the thermal stress of high-rise buildings was fully analyzed. Several suggestions were provided for the structural design and optimization of high-rise buildings.
Effect of Surface Motion on Heat Transfer and Pressure Force from Multiple Impinging Jets– A Numerical Study
Authors: Chitsazan Ali , Klepp Georg , Glasmacher Birgit
Published: March 2022

The effect of jet arrangement, jet Re number, jet exit angle (θ), the nozzle-to-surface distance (H/d), jet-to-jet spacing (S/d) on the heat transfer, and pressure force performance from multiple impinging round jets on a moving flat surface have been numerically evaluated. There is a minor difference between in-line and staggered arrangements on a moving flat surface. The averaged Nusselt number on a moving flat surface reduces with an increase in the relative velocity (VR). The surface motion effects become more pronounced on the local Nu distribution at low Re, small S/d, large H/d, and angled jets for a moving flat surface. The pressure force coefficient on a moving flat surface is highly dependent on the H/d and θ but relatively insensitive to the VR, Re, and S/d within the range examined. Two correlations are developed and validated for the average Nu and force coefficient and the agreement between the CFD and correlation is found to be reasonable.

Published: March 2022

Auxiliary boilers onboard motor ships are the subject of ongoing research. Steam is produced by an auxiliary boiler for fuel heating and cargo oil pumping turbines. This marine boiler is a pressure jet burner water tube auxiliary boiler with a 70-80% efficiency rating. The goal of determining the process and components of irreversibility loss in a system is to identify the process and components of exergy losses. The second law of thermodynamics and the concept of irreversible entropy production are the foundations of this study's exergy technique of analysis. This concept of considering entropy at a given steady-state condition rather than as a change in a process is also one of the features of this exergy analysis of the marine oil-fired boiler. The exergy loss in the combustion chamber was calculated and determined to be 35024 kJ, which is the maximum irreversibility in this maritime auxiliary boiler. A numerical analysis of the current nozzle jet burner is undertaken to evaluate the enhancement of the combustion process. The temperature and velocity contour of the fuel stream passing through the nozzle of this auxiliary boiler's burner depicts atomization.
Some Musings about William Hasker’s Philosophy of Mind
Authors: Goetz Stewart
Published: March 2022

While William Hasker and I for the most part broadly agree in our opposition to much of the contemporary philosophical community concerning issues in the philosophy of mind that he discusses in his book, there are nevertheless seemingly some domestic disputes between him and me about certain matters concerning the nature of events involving the self. In this paper, I will focus on two of these disagreements. The first disagreement concerns Hasker’s treatment of what is widely known today as the argument from reason and whether the events involved in our reasoning are essentially causal or teleological in nature. The second disagreement is about Hasker’s account of libertarian freedom, and whether agent causation is required to explain our free choices.
Some Puzzles about Molinist Conditionals
Authors: Koons Robert C.
Published: March 2022

William Hasker has been one of the most trenchant and insightful critics of the revival of Molinism. He has focused on the “freedom problem”, a set of challenges designed to show that Molinism does not secure a place for genuinely free human action (Hasker 1986, 1995, 1999, 2000a, 2000b, 2011). These challenges focus on a key element in the Molinist story: the counterfactual (or subjunctive) conditionals of creaturely freedom. According to Molinism, these conditionals have contingent truth-values that are knowable to God prior to His decision of what world to actualize. This divine “middle knowledge” is supposed to enable God to execute a detailed plan for world history without any loss of creaturely freedom. Hasker has argued that this middle knowledge nonetheless deprives us of the power to do otherwise than we do, a crucial element in human freedom and responsibility.

I hope to accomplish three things in this paper. First, I want to step back a bit and explore the nature of the conditionals of creaturely free decision-making (the CCFs), bringing out some of the difficulties in delimiting their scope and nature. Second, I will explore the implications of different answers to an important question that has not been addressed in the literature: whether we have counterfactual power over the conditionals of divine freedom. And, third, I would like to recommend to Molinists a revision that offers a solution to the freedom problem.

Kamu Borcunun Uzun Dönem Faiz Oranları Üzerindeki Etkisi: OECD Ülkeleri Üzerine Ampirik Bir Uygulama
Authors: Konya Sevilay , Duran Mahmut Sami
Published: March 2022

Kamu borçlarında meydana gelen artışlar, büyüme, bütçe açığı, enflasyon gibi pek çok ekonomik değişken üzerinde olumsuz etkilere yol açabilmektedir. Özellikle ortaya çıkan belirsizliklerle birlikte borçlanmanın ortaya çıkaracağı artan maliyet, faiz oranlarının yükselmesine yol açmaktadır. Öte yandan artan faiz oranları yatırım oranlarını azaltarak ekonomik büyüme oranlarının azalmasına yol açmaktadır. Bu nedenle kamu borcu, uzun dönem faiz oranları kanalıyla ülkelerin makroekonomik değişkenlerini de doğrudan etkileyen önemli faktörlerden biri olmaktadır. Uzun dönem faiz oranlarının kamu borcu üzerindeki etkisi bu çalışmanın amacını oluşturmaktadır. Bu amaçla çalışmamızda 15 OECD ülkesinde uzun dönem faiz oranı, kamu borcu, enflasyon ve ekonomik büyüme arasındaki ilişkiyi belirlemek için 1995-2020 dönemine ait yıllık verileri panel veri analizi yöntemleri ile test edilmiştir. Çalışmada uzun dönem faiz oranı ile kamu borcu arasında bir ilişki bulunamamıştır. Ancak nedensellik analizi sonucunda uzun dönem faiz oranı ile kamu borcu arasında karşılıklı nedensellik ilişkisi belirlenmiştir.

Zanim doprowadzisz do pogromu: między doświadczeniem etnograficznym z badań terenowych w społecznościach romskich a antropologicznym tekstem naukowym
Authors: Witkowski Maciej
Published: March 2022

Autor prezentuje materiały empiryczne pozyskane w trakcie terenowych badań etnograficznych w latach 2011–2016 wśród Bergitka Roma w jednej z karpackich wiosek. Badaniami objęto także przedstawicieli organizacji non profit oferujących usługi w zakresie integracji Romów i miejscowych górali. Znane są obserwowane w całej Europie trudności związane z wprowadzaniem polityki integracji Romów. W ostatnich latach znaczna liczba publikacji naukowych koncentruje się na „pragmatycznych” aspektach nowych sposobów rozwoju kulturalnego odbywających się w ramach tak zwanej „demokratycznej” zmiany w obrębie społeczności romskich. Miała ona zaowocować poprawą jakości więzi między Romami i nie-Romami. Ocena przedsięwzięć określanych jako „integrowanie Romów” jest różna dla poszczególnych podmiotów, posiadających różne intencje, doświadczenia i przekonania na temat racjonalności tego typu działalności. Autor argumentuje, że antropolodzy w pewnych sytuacjach powinni być gotowi na zakwestionowanie ogólnego sensu działań integracyjnych, co jednocześnie wydaje się trudne z moralnego punktu widzenia. W tekście autor posługuje się rozróżnieniem między pojęciami „gęstych” i „rozrzedzonych” przekonań moralnych, które zostało zaproponowane przez Kwame’a A. Appiaha w jego koncepcji „kosmopolitycznej etyki”.
The Fourth Act in Socio-Legal Scholarship: Playing With Law on the Sociological Stage
Authors: McKnight Janet
Published: March 2022

The emerging narrative of law as a social phenomenon—as opposed to a legal phenomenon— presents pressing questions about what it means to take a sociological approach to law, why the discipline needs retelling from a sociological vantage point, and how this relatively new narrative can be told. I consider these “baseline” questions of socio-legal studies through a careful dissection of Roger Cotterrell’s assertion that a sociological understanding of legal ideas “consistently and permanently addresses the need to reinterpret law systematically and empirically as a social phenomenon.” By deconstructing Cotterrell’s statement, I will explain how a sociological approach provides a vital analytical lens through which to appreciate not only how law works (succeeds or fails) in different social contexts but also how law acts as a social phenomenon. Drawing upon historical and contemporary research examples, I argue that law must be studied as if on a sociological “stage” upon which different actors perform and experience social “acts” within the “theater” of the legal discipline. I will explain why a sociological approach to law is vital for understanding how each “act”—each social phenomenon of law—plays out in the context of other phenomena, including globalization, transitional justice, and the evolution of socio-legal scholarship itself.
Resinicization and Digital Citizenship in Hong Kong: Youth, Cyberspace, and Claims-Making
Authors: Adorjan Michael , Yau Ho Lun
Published: March 2022

Under the “one country, two systems” model fashioned after its handover to China in 1997, Hong Kong, a Special Administrative Region of China, is to retain its rule of law, capitalist system, and accompanying political and ideological independence. However, tensions remain centered on concerns held by many Hong Kong citizens over the “resinicization” of Hong Kong, related to anxieties regarding the putative erosion of political and ideological freedoms. This paper examines the claims-making of the student activist group Scholarism, who effectively used Facebook to raise awareness of and successfully resist a government proposal to introduce a national education curriculum into Hong Kong schools. Scholarism’s resistance and ability to mobilize mass demonstrations against the government is significant considering the lack of democratic channels in Hong Kong. Implications are explored for the examination of how claims-making in cyberspace impacts the social problems process, especially in non-democratic and post-colonial contexts.
