A rare case report of extra medullary plasmacytoma involving the posterior mediastinum coexistent with multiple myeloma
Authors: Dhulipalla Lohitha , Karki Monika , Huq Ammar , Rana Anshuma
Published: July 2021

Introduction: Plasma cell neoplasms are characterized by the clonal proliferation of plasma cells. They include monoclonal gammopathy of undetermined significance, multiple myeloma, and solitary osseous or non-osseous plasmacytoma. Multiple myeloma is characterized by the proliferation of plasma cells in the bone marrow and can result in extensive skeletal destruction, whereas plasmacytoma is characterized by the proliferation of plasma cells restricted to one area of the body.

Case Report: A 65-year-old female presented for workup of incidental mass noted on computed tomography (CT) of the chest. She was noted to have posterior mediastinal plasmacytoma with elevated IgA and free lambda light chains on serum electrophoresis. She subsequently underwent the bone marrow biopsy which revealed multiple myeloma. The patient was diagnosed with IgA lambda multiple myeloma with a posterior mediastinal plasmacytoma with multiple bony lesions. She underwent radiotherapy with interval resolution of posterior mediastinal mass and currently on chemotherapy for multiple myeloma.

Conclusion: Once plasmacytoma is diagnosed, a further workup for multiple myeloma is needed as treatment is entirely different for both types of plasma cell neoplasms.

Virus komputer  sifatnya dapat merusak misalnya dengan merusak data pada dokumen, membuat pengguna komputer merasa terganggu dengan keberadaannya dalam sebuah sistem komputer, maupun tidak menimbulkan efek merusak sama sekali. Antivirus  adalah sebuah jenis  perangkat lunak  yang digunakan untuk mendeteksi dan menghapus virus komputer  dari sistem komputer.Metode CRC32 sebagai metode pada proses scanning salah satunya adalah metode CRC32. Sesuai dengan fungsi utama dari fungsi hashing, CRC32 berfungsi untuk mengambil penanda dari sebuah file yang nantinya akan dipakai sebagai acuan untuk memeriksa apakah suatu file adalah file virus atau bukan. Kecil  sekali kemungkinan bahwa dua buah file mempunyai nilai CRC32 yang sama. Hal ini disebabkan perbedaan 1 bit saja pada file akan mengubah nilai CRC32 file tersebut.Perhitungan indeks akan dikonversi kedalam bentuk decimal agar diketahui jelas nilai indeksnya dan dilakukan perhitungan terhadap file yang akan dikoreksi dengan menggunakann bahasa pemrograman visual basic studio 2010

Authors: Ratnawati
Published: July 2021

Mass concrete is a concrete casting with a large enough volume, usually used for foundations, bridges,dams and so on. The heat of hydration in the mass concrete causes a temperature difference between the inside and the outside of the concrete surface. This can cause cracks in the concrete,where the temperature inside the concrete has a higher temperature rise than the outer surface yhat is in contact with the environment. One way to control the temperature of the concrete is to use a post cooling system.Post cooling system design requires knowledge of temperatur distribution in concrete. The research was conducted by varying the cooling pipe materials used,namely steel,PVC,and PEX where the cooling water discharge and temperatur were constant.The result of the research that have been carried out show that with the same cooling water discharge and temperature,concrete with PVC cooling has a higher temperature than PEX cooling pipe or steel.

The quality and quantity of mother and child attachment have often been discussing. Nevertheless, how the quality and quantity of the relationship between father and son, especially in shaping the child's personality is still rarely found. In the life of a child, sometimes role, the father is not felt because his figure is busy outside the home. Also provides an assumption that the father does not influence raising and educating children. The context of Islamic education in the family, the figure of the father, is the spiritual basis that underlies the role of parents in educating their children. A person's character formed early on. In this case, the role of the family is indeed very influential. The education of the father in the family is critical and is a fundamental pillar of character building for a child. From a child's father learns, hardened, brave, responsible, and easy to get along with the outside world. This study aims to present the role of fathers in shaping the character of children in terms of the study of texts and contexts through the field of psychology in Islamic education. The contextual study presents the latest research that proves the influence of the father in many ways for children and terms of the text of this study will present the primary sources of guidance for Muslim life, namely the Qur'an and the Hadith. So the implications given are not only normative but grounded to be able to broaden understanding and add new constructs for the implementation of the father and son relationship.
The Inferred Determinants of Employees’ Turnover Intention: A Comparison between Japanese and Foreign-Owned Firms in Japan
Authors: Hasegawa Rei , Hasegawa Shinji , Akiyama Takashi
Published: July 2021

This study compares the factors that are inferred to directly and indirectly influence the process of determining employees’ turnover intention in Japan. This study focuses on the differences made by firm type, that is, Japanese firms vs. foreign-owned or foreign-affiliated firms. Multiple-group structural equation modeling was attempted by applying factors such as perceived organizational support, the positiveness of a worker, firm-specific skills, organizational commitment, perception of career opportunities within the current firm and in other firms, and turnover intention. It was found that the inferred determinants of turnover intention differed by firm type; specifically, career prospects, either internal or external, do not directly affect turnover intention in Japanese firms. For workers in foreign firms, positivity is significantly higher than that of Japanese firms. Positivity plays a crucial role in both firms; moreover, our study provides supporting evidence of the existence of sub-markets in Japan and shows that the transition of workers from foreign-owned to Japanese firms might be rare.
Impact of Climate Change on Budget Balance: Implications for Fiscal Policy in the ECOWAS Region
Authors: Yahaya Binta , Nkwatoh Louis Sevitenyi , Jajere Babagana Adamu
Published: July 2021

The budget deficits of the Economic Community of West African States (ECOWAS) have been widening over the years. This study investigated the impact of climate change on budget balance and projected its implication for fiscal policy in ECOWAS countries. The two-step dynamic GMM method was applied for a balanced panel data of 14 countries from 2008 to 2018. The study found that rainfall is the only climate variable that increases budget deficits. Other macroeconomic variables: debt to GDP ratio and inflation were also responsible for the widening budget deficits. A major policy implication of this finding is that extreme and unpredictable rainfalls will distort the fiscal balance of ECOWAS countries by either reducing the revenue generation outlets or by raising expenditures. This will lead to more borrowing that will further widen the existing budget deficits through debt servicing, hence, making the respective governments to pay less attention on other sectors of the economy. Thus, ECOWAS countries need to expand their revenue generation sources either by creating an enabling environment for more businesses and investments to strive or by engaging in more foreign direct investment (FDI).

A contribution to the study of Milan Zloković's architecture in Belgrade from the interwar period
Authors: Banković Angelina
Published: July 2021

Numerous published papers have covered the life and work of architect Milan Zloković. He has been presented as a pioneer of the modern movement in Serbian architecture and one of its most prominent representatives, as well as one of the most eminent Serbian architects from the first half of the 20th century. His extensive opus, which officially contains just over 170 designs, has been analyzed in detail. However, during the musealization of his legacy, in the process of forming the Bequest of Milan Zloković, and in cooperation with Belgrade City Museum and the Milan Zloković Foundation, over 50 previously unknown designs were identified. This was the result of the extensive research of vast amounts of project documentation, preserved in his family house and previously unavailable to researchers. This paper presents one part of that research, specifically the designs for several structures in Belgrade, originating from the interwar period. The first section presents a short biography of Zloković, especially with regard to the period from 1925 to 1937. The second section is dedicated to his designs, each of which is presented separately. The section is further divided into two segments, the first of which is built structures, and the second, unrealized projects. Included in the built structures are also a few alterations and extensions. The paper is mostly based on a study of primary sources, designs from the Milan Zloković legacy and documentation from the Historical Archive of Belgrade, as well as previously published research.
Who speaks for Hume: Hume's presence in the 'Dialogues concerning Natural religion'
Authors: Davidović Aleksandra
Published: July 2021

One of the reasons for many different and even opposing interpretations of Hume's Dialogues Concerning Natural Religion is the absence of consensus concerning the question of which character in the Dialogues represents Hume. In this paper I argue that taking Philo to be his primary spokesperson provides us with the most consistent reading of the whole work and helps us better understand Hume's religious viewpoint. I first stress the specific dialogue form of Hume's work, which requires us to take into account literary tools such as irony and double-talk when interpreting it. From there I proceed to show why I believe that my hypothesis is better supported than the other two main hypotheses concerning Hume's presence in the Dialogues, the first one being that Cleanthes represents Hume and the other one that none of the characters consistently speaks for Hume but rather that the whole structure of the work does that. Although there is both textual and historical evidence which suggests that Hume favoured Cleanthes, I show that his opinions deviate from Hume's well-known views on important subjects such as scepticism, morality and Christianity, while Philo's opinions on these subjects agree with Hume's almost verbatim. The second hypothesis is proven to be wrong by the fact that Philo actually consistently defends Hume's opinions. Finally, I argue that Philo's understanding of true religion as a philosophical position devoid of any religious import agrees with Hume's religious scepticism.
Joint criminal enterprise in the practice of international criminal tribunal for the former Yugoslavia
Authors: Čučilović Irena
Published: July 2021

Joint criminal enterprise (JCE) is the institute first applied by the International criminal tribunal for the former Yugoslavia (ICTY) in the Tadić case, and thereafter further shaped through the practice of the ICTY despite the fact that JCE as a form of individual responsibility is not mentioned anywhere in the Statute of ICTY, neither implicitly nor explicitly. Although today there is no doubt that the Joint criminal enterprise is an institute of international criminal law, which was very often applied in the practice by both ICTY and other international ad hoc tribunals, the serious remarks to this institute do not abate. It's pointed out that this is an institute that "was created" to ensure the conviction of the defendants, which procedurally affects the prosecution, which is relieved of the burden of proving criminal responsibilities and the specific roles of each of the participants in the JCE. Besides that, at the time when this doctrine was formulated, it was not entirely clear whether it was a form of commission or a form of complicity. Only a couple of years later, in the Milutinović et al. case, the ICTY stands out that the liability based on the JCE doctrine, in fact, is a responsibility for the commission, which further compromised this doctrine. Questionless, the application of the Joint criminal enterprise doctrine in practice leads to serious violation of the fundamental principles of contemporary criminal law. With general review of the Joint criminal enterprise doctrine, in this piece of work, the author considers one case of conviction under the third (often referred to as "extended") form of JCE, in order to point out the key problems which this doctrine produces in practice.

The most effective way to preserve agricultural product is drying. However, vegetable drying is an energy-consuming procedure. Convective drying is the mode considered in this work. The study intends to explore a new way of pumpkin drying, which reduces drying time and minimizes heat consumption. The study considers pumpkin thin slices and pumpkin samples with cubic shape. The samples were subjected to free convection airflow at different temperatures (40 °C, 46 °C, 52 °C, and 60 °C) for each run. A varying airflow temperature was also considered. Airflow velocity was generated by buoyancy forces for each temperature. Drying curves were plotted and fitted to the widely used thin-layer drying models. The modified Page model came out as the best-fitted model. The effective diffusivity coefficient was determined for each case using the slope moisture curve. It appeared that diffusivity was high and drying time was short, for high temperature. Drying processes for slice configuration and cube configuration showed that the latter was more efficient. When applying the regime of increasing temperatures to the cubic samples, data analysis showed that effective diffusivity was higher during the third step in comparison to all the other drying temperatures and the total drying time was similar to that obtained at drying regime on high temperature. With this procedure, the final consumed energy was much less and the time was shorter.
Istine i zablude o kreativnom učenju

Creativity in a tangible and intangible product is an attempt at overcoming the current situation in the field of creation and the life of the person who creates the product. The main feature of creativity is an effective novelty in relation to something familiar, which means that it offers an appropriate solution to the problem to which it refers. The paper criticizes the thesis on the innateness of creativity, according to which a person is creative on the basis of heritage, which would practically mean that education does not have any special significance for the creation of creative works. The criticism is based on the current theories of creativity that indicate the developmental nature of creativity and emphasize the role of learning in the development of creative potentials. The new is built on the existing knowledge through learning, which implies creative processing of information, becoming familiar with it, understanding, acceptance and placement of that information in one's own knowledge-base of what has been learned. The more creative the learning process is, the greater the chances that it will encourage the creativity of the learner in relation to the existing knowledge and the aspiration for its re-examination and change. The developmental approach to creativity, which begins with creative learning, has been linked to the theory of growth and fixed mindsets about human nature, which addresses our capacity to adapt, change, and grow. In the continuation of the paper, the conditions are considered that would support to a greater extent the creative learning in school. In the final part of the paper, the limitations of this approach are discussed and questions proposed for future research.

Benzoic acid has a wide use primarily in food but it is also used in cosmetic, pharmaceutical and other products. Because of noted carcinogenic and toxic characteristics under certain concentration it is considered a pollutant that becomes an important environmental problem. In this study, commercial activated charcoal was tested for the removal of benzoic acid from aqueous solutions. Removal of benzoic acid was investigated in a batch and column system under various values of pH, temperature, activated charcoal granulation and mass. The analysis of all samples was performed by visible absorption spectrometry. The optimum conditions for benzoic acid removal in a batch system were found to be pH 3, contact time of 60 min, the temperature of 273.65 K and adsorbent dose of 10 g L-1. The benzoic acid removal can be performed in a column system as well in which the highest quantity of benzoic acid is removed during the first 20 min (70%) and saturation occurs after 70 min. The used benzoic acid removing methods can be characterized as simple, economical and fast and requiring no chemical treatment.

In this study, the modified stability-indicating RP-HPLC method was validated for quantitative analysis of amlodipine besylate in the presence of its impurity D (3-ethyl 5-methyl 2-[(2-aminoethoxy)methyl]-4-(2-chlorophenyl)-6-methylpyridine-3,5-dicarboxylate). The method was applied for the determination of an analyte in the tablets and irradiated samples packed in the primary packaging (Alu/PVC/PVDC blister packaging). The efficient chromatographic separation was achieved using a ZORBAX Eclipse XDB-C18 column (4.6×250 mm, 5 mm) with isocratic elution of mobile phase which consisted of acetonitrile:methanol:triethylamine solution (15:35:50, v/v/v) (pH 3.0). The flow rate of the mobile phase was 1 mL min-1, while the detection of amlodipine besylate was carried out at 273 nm. Amlodipine besylate and its impurity D were identified at the retention times of 16.529 min and 2.575 min, respectively. The linearity of the method with the coefficient of determination of 0.999 was confirmed in the concentration range of 10 - 75 µg mL-1 for amlodipine besylate. The limit of detection was 0.2 µg mL-1, while the limit of quantification was 0.66 µg mL-1. After UV and Vis radiation of the tablets packed in the primary packaging, the content of amlodipine besylate was reduced by 22.38% and 19.89%, respectively. The presence of new degradation products was not detected under the given chromatographic conditions. The photodegradation of amlodipine besylate followed pseudo-first-order kinetics. Based on the half-life of amlodipine besylate (38.4 days for UV radiation and 43.3 days for Vis radiation), it was concluded that amlodipine besylate in the tablets has satisfactory photostability after its packing in the Alu/PVC/PVDC blister packaging.
Model in problem space of a legacy system for the support of design and production of rubber compounds
Authors: Spasić Aleksandar
Published: July 2021

The fourth generation legacy system used for designing rubber compounds contains valuable information related to rules of business, knowledge, methods and results in compounding. In order to leverage the accumulated knowledge or design new applications related to compounding it is important to define a domain model based on the existing system used with remarkable success in the past twenty years. Due to the lack of both source and binary code, standard software reverse engineering methods could not be applied in this situation. In the process of manufacturing rubber products, the greatest attention is focused on a further understanding and improvement of the development of new rubber compound formulations, design technology and improvement of the existing ones. A basic problem that needs to be resolved is what kind of information is needed about a particular rubber compound. The problem of building an elastomer formulation from the ground up is complex and can easily entail thousands of choices by the compounder. This problem is not a trivial one, and it can only be resolved on the basis of available science-based elastomer technology as well as software engineering methods and models. Modelling in problem space is used as a research method in this paper. Model of problem space (MOPS) deals with creating and understanding of the problem, primarily the problem that a potential user of the system faces. The modelling output transcends both data and code and results in a suite of visual models or diagrams created with use of Unified Modelling Language (UML).
