Decoupling as a Measurement of the Environmental Impact of Economic Growth
Authors: YAREMOVA MARYNA , MYTROFANOVA ANNA
Published: November 2022

Accelerated population growth on the planet leads to an increase in production, which causes the need to increase the production of raw materials, expand the construction of industrial structures, increase social infrastructure facilities, and so on. Consequently, the creation of appropriate conditions for the existence of modern civilisation leads to an exhaustible use of natural resource potential and an aggravation of global environmental problems that have a destructive impact on the environment. Considering the above, the issue of monitoring environmental consequences from economic activities acquires significant theoretical and practical significance, which determines the relevance of the subject matter. The purpose of this study is to substantiate the theoretical and methodological foundations and applied aspects of measuring the decoupling effect under the condition of an environmentally oriented course of social development. The methodological basis of the study is the methods of empirical research and theoretical cognition, in particular the method of formalisation, abstract and logical, observation, measurement, and comparison. The study used general scientific methods and techniques, in particular, analysis and synthesis, analogy and economic modelling, induction and deduction. The paper systematises the opinions of leading researchers on understanding the concept of decoupling based on the resource approach and environmental impact. The analysis provided the basis for investigating the impact of production on the environment in the context of regions in 2016-2020 and visualising an integral indicator of the regional decoupling effect. Generalisation of the value of factors in Ukraine as a whole allowed projecting the environmental consequences of economic activities for the future. The practical significance of the study is to substantiate practical recommendations for strengthening environmental policy and minimising the destructive impact on the environment, considering the challenges associated with military operations on the territory of Ukraine. Further research is aimed at considering the achieved effect of decoupling within certain branches of the national economy

The biological environment is crucial for the bioactivity of modern calcium-silicate cements. Most of the studies of the materials were performed under ideal conditions, which are difficult to achieve in clinical practice. The aim of this study was to evaluate the surface characteristics of MTA+ (PPH Cerkamed, Medical company, Polish) and Biodentine in PBS and blood environments with a non-contact 3D optical profilometer Materials and methods: Retrograde cavities were prepared on the root surfaces of freshly extracted teeth. The cavities were filled with MTA+ or Biodentine, and the samples were immersed in PBS or Blood and placed in an incubator for 28 days. The surface of each specimen was scanned using a 3D optical profilometer at three different time points (1, 3, and 28 days). Statistical calculations were carried out using IBM SPSS Statistics (v.25), and significance was fixed at p <0.05. Results: Both materials showed that blood contamination affects the roughness of their surface. Both materials placed in blood contaminated conditions show reduced and constant roughness during the reported time periods (p> 0.05). This study showed that the surface roughness of MTA+ and Biodentine was adversely affected by blood pollution.

Authors: Ismoyo Muhammad Bayu , Pratama Yudha , Irianto Ahmad
Published: November 2022

Special autonomy is a political consensus on the desire of the Papuans to live in prosperity by considering their indigenous rights. Two decades of the implementation of Special Autonomy for Papua, it is still considered ineffective to answer the crucial demands, such as political rights, material welfare, and indigenous participation in the development. Political participation of Papuan indigenous (OAP) is expected as the main issue of which has crucially affected the mandatory aspects, such as political conductivity, development objectivity, social welfare, and security. This research aims to figure out the importance of political participation to the OAP and how it can affect the special autonomy enforcement in Papua. The results show that political participation of Papua considerably contributes to the local institutional involvement, addressing political conductivity, directing the development target, and realizing the deliberative policy. In other findings, political supervision is highly required to be evaluated in ensuring the optimizing of political participation for OAP.
More Things in Heaven and Earth: Some Musings on History and Hope
Authors: Eklund Rebekah
Published: November 2022

While Allison’s book demonstrates that apologists and skeptics can neither prove nor disprove the resurrection on historical grounds, he also suggests that the evidence tips in favor of historicity. His anti-materialist and anti-reductive approach leads him to a fascinating exploration of other phenomena, including the rainbow body, which raise the question of the uniqueness of Jesus’s resurrection.
The Resurrection as Category Error: A Response to The Resurrection of Jesus
Authors: Joseph Simon J.
Published: November 2022

The Resurrection of Jesus provides an explanatorily powerful hypothesis accounting for the emergence of “resurrection” belief within the framework of the comparative study of religion. This review article focuses on a central question that illuminates the methodological and theoretical implications attending this project, namely, “What does it mean to say that Jesus ‘rose from the dead?’” Challenging the idea that this explanatory model allows for Christian theological claims to be inferred, this article explores how the category of “resurrection” can be problematized in historical discourse—not only because “resurrection” implies an eschatological narrative that was never fulfilled—but also to avoid the theologically freighted implications of the category in the historical study of Christian origins.
Why Do Christians Believe in the Resurrection of Jesus?
Authors: Jipp Joshua W.
Published: November 2022

In conversation with Dale Allison’s The Resurrection of Jesus, this short article argues that, while critical historiography cannot establish with complete certainty the veracity of Jesus’s resurrection, this is not a problem for contemporary believers who confess that God has raised Jesus from the dead. The NT writings indicate that the church’s experience of the risen Christ and the Spirit of Christ validates its belief in the historical reality of Jesus’s resurrection.
URBAN DECLINE AND CHALLENGES OF REVITALIZATION PROJECT: A STUDY OF MARTIN QUARTERS KARACHI
Authors: Nazir Humaira
Published: November 2022

With the emergence of the housing problems in Karachi, new housing schemes are being launched on the city’s outskirts. Instead of launching new housing in the suburbs, this research aims to study one of the existing dilapidated areas within the city and considering redevelopment as an alternate to eviction. This research revolves around the qualitative approach that involved surveys of Martin Quarters, focused gathering discussions and on-site meetings with involved stakeholders. A total of 50 respondents were picked using the multistage random sample method. The analysis is based upon the perception of householders about the revitalization of the area and examining the actual planning of government quarters that aimed to house federal employees in Karachi in the first phase of development of Karachi in 1947-1957 and current planning techniques used by people guided by traditional ways of living. The paper finds that the land on which Martin Quarters are situated is an expensive land of State that is being wasted due to the low-density settlement and also occupied illegally by many residents. Furthermore, it is improperly planned and growing haphazardly due to the increase in the population of the city and is at risk of decay and chaos. The paper concludes that the revitalization of Martin Quarters by the government is only a solution to stop the decaying of this area and it will benefit the general masses by enhancing accommodation capacity.

Published: November 2022

Background: The placenta plays a crucial role in sustaining pregnancy and supporting healthy foetal growth and function. Placental morphology predicts illness patterns in adults and foetal development. Birth weight is a significant predictor of a child's survival, healthy development, and growth. The connection between birth weight and perinatal outcome has long been understood in obstetrics. As is generally known, low birth weight is a known risk factor for the child's long-term health. The aim of the study was to find any association between birth weight, gender and placental morphology. Methods: An analytical cross sectional study was conducted in the anatomy department of  Anatomy, Bhaarath Medical college and  Hospital, Chennai. Placentae of 200  were collected. Morphological analysis including placental weight, number of cotyledons, site of umbilical cord insertion and fetal and maternal surface area, were measured in normal and low birth weight babies. Results: Birth weight showed a positive connection with gestational age. Birth weight and greater values in men were positively and significantly correlated with placental parameters (p 0.001). Regression models employing the newborn's sex and placental morphometry were used to estimate the birth weight; weight (R2=0.461), surface area (R2=0.411), and volume (R2=0.456) were calculated.
Efecto de tres arreglos de siembra sobre variables agronómicas, productivas y pato métricas en el cultivo de chiltoma (Capsicum annuum) en camas biointensivas
Authors: Somarriba-Toruño Ridder Alberto , L. M.
Published: November 2022

El chile dulce (Capsicum annuum L.), conocido en Nicaragua como chiltoma, es cultivada principalmente en pequeñas áreas de producción, en sistema de monocultivo, destinadas para los mercados local, sin embargo la producción ha ido creciendo debido a la alta demanda de los mercados, sin embargo este cultivo demanda bastante atención y tecnología productiva ya que la presión de las plagas de insectos y enfermedades ha ido aumentando gradualmente debido a las condiciones climáticas ocasionadas por el calentamiento global y la intervención del hombre sobre el medio ambiente. El presente estudio tuvo como objetivo evaluar características agronómicas, productivas y patométricas del cultivo de chiltoma bajo tres arreglos de siembra como fueron: tresbolillo, cuadrado y arreglo lineal en cambas biointensivas. En cada tratamiento se tomó variables de altura, grosor de tallo, número y peso de frutos, además de evaluar la incidencia y severidad de enfermedades en el cultivo. Obteniendo como resultado que existe diferencia significativa entre la variación de arreglos de siembra en las variables de altura y grosor del tallo siendo el arreglo de siembra tres bolillos el que presento los mayores valores. Desde el punto de vista productivo se recomienda el arreglo lineal ya que con este se obtuvo una mayor cantidad de frutos. En cuanto a patometria, durante el cultivo se presentó la enfermedad cercosporiosis del pimiento causada por el hongo Cercospora capsici, la cual incidió en el 100% del cultivo por lo que podemos decir que los arreglos de siembra no influyeron en la incidencia de la misma.

Authors: Misbahuzzaman Khaled , Ingleby Kevin
Published: November 2022

Effects of arbuscular mycorrhizal (AM) and ectomycorrhizal (EM) inoculation on mycorrhiza formation and development in E. camaldulensis seedlings were assessed in this study. Two experiments, the first with AM fungi and the second with EM fungi, were set up successively using vermiculite-peat (VP) as growth medium, and 2.5 mg l-1, 5.0 mg l-1, 10 mg l-1 and 20 mg l-1 phosphorus (P) Ingestad's nutrient solution in each experiment. The AM experiment using three AM inocula (including Glomus clarum Nicolson and Schenck. (isolate BR148-1) and Gigaspora rosea Nicolson and Schenck. (isolate FL105-5) and one from a trap culture of Bangladeshi soil) resulted in 30-50% colonisation; most colonisation was by G. clarum BR148-1 and was the highest at 10 mg l-1 P (>50%). In a similar experiment using five isolates of Pisolithus tinctorius (Pers.) Coker and Couch., only isolate K55 resulted in colonisation >15% most of which occurred at 2.5 mg l-1 P (>25%) while the other isolates resulted in <1% colonisation. This study showed that E. camaldulensis tended to be colonised more readily by arbuscular- than ecto-mycorrhizal fungi in the initial period of seedling growth. There were indications that the species could become ectomycorrhizal after 16 weeks of growth in glasshouse, but that proper care should be taken to select appropriate and compatible EM inoculants.

Labeo gonius is a threatened species. It was successfully bred by PG (pituitaiy gland) injections at the Arabpur Fish Farm, Jessore. Three pairs of fish were collected from Brahmanbaria district and were transported to Jessore. After rearing for one month only one pair was induced to breed. The female (700g) was first injected with a dose of 2.5 mg PG/kg body weight. The second dose of 6 mg PG/kg body weight was administered 6 hours after the first dose. The male was administered a single dose of 2 mg PG/kg body weight 3 hours after the first dose was given to the female. Eggs and milt were stripped for fertilization 4 hours after the second dose of female. Hatching occurred after 18 to 19 hours at 27”C-28°C in a cemented conical bottom incubation jar with water flow of 0.3 1/sec. Fertilization and hatching rate of 87% and 81%, respectively were obtained. Yolk sac absorption occurred after 56-60 hours of hatching. A total of 500g (approx. 0.1 mil'ion) spawn of average length 7 mm was collected. Nursing of the spawn was done in a small pond measuring 0.065 ha. After 14 days of nursing they attained an average length of 34 mm and weight of 450 mg with 37% survival. Fry were thinned out by transferring two-third of the fry to another pond measuring 0.117 ha and were reared for 14 days. The survival of the fry in the first and second ponds was 74% and 78% , respectively and the length ranged from 44 mm to 46 mm after two weeks. The weight varied between 830 mg and 880 mg.

Fusion splicer is used to re-splice these points at different humid conditions to analyze the splicing loss dependency. From this study it has been found that different humid conditions affect the splicing losses to a large extent.
LEGACY OF COLONIAL ARCHITECTURE IN KHULNA CITY
Authors: Mridha A. M. M. H. , Khan M. A.
Published: November 2022

Khulna city was established during the British colonial period as a sub divisional center in 1842. The city is characterized by a number of colonial buildings along K.D. Gosh Road forming civil line of the government. On the other hand, artifacts of private nature are scattered within the city. These colonial artifacts have distinct aesthetic value but may not be categorised according to definite tenets of style. A City can be judged from two approaches; one is being the historical approach, other being the structural analysis. These judgments are in fact value judgments and the basis of urban aesthetics. For that reason aesthetics emerges as a tool for the investigation of the study. However the study is confined only with the visual qualities for judgment of buildings as artifacts in Khulna city in historic time frame of British Colonialism. Typological significance of urban artifacts that also determine the character of the aesthetics and have been taken care. As a case study, city aesthetics of Khulna was assessed by identifying the nature and the type ofinvolvement in their development process. From the findings, types and the quality they produce as building block of urban image divided the whole artifacts into components of urban aesthetics. The outcome of the study will help city dwellers to receive, synthesize, assimilate and classify the colonial artifacts as components of perceiving the colonial image of Khulna city. Again a significant practical value of such studies would be drawn from an area of concern to those architects, planners and policy makers whose primary problem is the design of housing for the rapidly expanding urban areas of the so called developing world. Here as elsewhere design solution must be congruent with the value system and culture of the community being housed.

The influence of light intensity on growth and biochemical constituents of two species of Spirulina; Spirulina platensis and Spirulina fusiformis was studied. Various light intensities of 1000, 1500, 2000 and 2500 lux were investigated. The best growth for both S. platensis and S. fusiformis were found at the intensity of 2500 lux and at 1000 lux both species showed slower growth. The results indicated that at highest light intensity the protein content increased while the carbohydrate and lipid content decreased. Maximum protein content of 59.2 % and 60.6% were found at 2500 lux for 5. platensis and S.fusiformis respectively. Maximum biomass productions were also achieved at 2500 lux for both the species and they were 2.1 and 2.2 g/1 for S. platensis and S. fusiformis respectively. Carbohydrate and lipid content was high at 1000 lux for both the species. Phycocyanin and carotenoid content was found higher at optimal light intensity of 2500 lux.

The involution of education refers to the phenomenon that education stagnates or cannot be transformed into another advanced mode after the social or cultural mode reaches a certain form at a certain stage of development. The main source of internal volume is negative sum game, where resources are limited, it is difficult to open source, and competition rules are exclusive. Faced with this kind of competition, people's investment increases but the total amount of society does not increase, so it is impossible to achieve a win-win situation of personal income and total amount growth. The root of the current education involution lies in the fact that the current education system can't meet people's demand for educational resources under the dual contradiction between employment and class. This phenomenon is particularly evident in the zero-sum exam competition represented by the college entrance examination. This paper puts forward that to solve the problem of education involution, we should handle the relationship between class contradiction, education equity, employment situation and education involution as a whole, and the concrete measures can be taken from the aspects of increasing rising channels, reforming the education system and alleviating employment pressure.

Since 2010, Chinese companies listed overseas have been frequently shorted. By issuing short-selling reports, short-selling agencies investigate and question the operations, information disclosure, and internal governance of these companies. These short-selling reports have accelerated the exposure of corporate problems and caught investors' attention. However, not all of the Chinese stock companies which have been short-sold have their share prices plummeting and never recovered since then. In the long run, there are still Chinese stock companies that are hardly influenced. For this study, two Chinese stock companies, Focus Media and Anta Sports, are selected, which have been shorted by muddy water institutions while have different market reactions. For comparison, the event research method is used to analyze the impact of short-selling events on their stock price changes, and reasons for which their reactions are different are discussed. Faced with opportunities and challenges, China Concept Stock companies should be prepared well, strictly abide by local laws and regulations, and conduct self-examination in a timely manner. Once a short-selling agency investigates and issues a targeted report, companies should respond quickly and be vigilant about the threatening parts in the report, so as to strive for stable development in the financing market.
