Thermal Rehabilitation of External Walls – Case Study
Authors: Stanca Simona 
Published: January 2024

Abstract
Both at national and international level, the present-day trends relate to the development of high-performance enclosing and insulation systems that make use of modern thermo-energetic rehabilitation methods.
Thermal rehabilitation works for the envelope of a building or for the building elements forming the envelope concern the diminishing of the heat losses by increasing the thermal resistances of the enclosing elements and limiting air infiltrations through glazed elements and joints.
In most Western European countries, national programmes aiming at the thermal protection of the buildings have been developed. The projects ran in gradual stages, starting after the energy crisis in 1973 and 1979, the outcome being a reduction of the energy consumption.
According to the Energy Performance of Buildings Directive issued by the European Commission, at present, buildings are responsible for approximately 40% of EU energy consumption and 36% of the energy-related greenhouse gas emissions (https://energy.ec.europa.eu/topics/energy-efficiency/energy-efficient-buildings/energy-performance-buildings-directive_en).
In the paper, a case study is presented, analysed from the point of view of energy efficiency through a new software for computing developed by the author called REBUILD, which leads to the choice of appropriate solutions for the thermal rehabilitation of an element of the building envelope. The recommended solution after the study is intended to bring the structure back to its optimal energy performance and to abide by the current regulations.
Properties of Microconcrete Produced with Fly Ash and Ultrafine Silica
Authors: Scripcă Sabina , Barbută Marinela 
Published: January 2024

Abstract
Microconcrete is an important subclass of regular concrete that lacks the coarse aggregate commonly found in standard concrete. This makes it a good candidate for certain casting operations, such as densely reinforced elements. Microconcrete also tends to have better workability and smoother flow in formwork elements than regular concrete. However, one of humanity’s current problems is air pollution caused by chemical, physical, or biological agents with harmful effects on the environment. Carbon dioxide (CO2) resulting from cement production is a major atmospheric pollutant. To align with sustainable development standards, the construction industry must seek alternative materials that are more environmentally friendly. This article presents a comparison of the properties of regular microconcrete and microconcrete with additives such as fly ash and ultrafine silica. This topic is important because environmental issues are becoming more pressing. The results show that using waste products as additives in microconcrete can provide a sustainable solution for reducing carbon dioxide emissions and environmental impact. Although lower strengths were obtained compared to traditional concrete, microconcrete with waste products can be used in various applications, such as the production of prefabricated construction elements or the rehabilitation of existing structures. Additionally, it can be used in the construction of paving stones, sidewalks, or industrial floors, contributing to reducing pollution and environmental impact.

Authors: Nouri Malek , Hajlaoui Abdessalem 
Published: January 2024

Abstract
With the global energy crisis and the emergence of sustainable development issues, architectural design must be mastered, not only to ensure a comfortable indoor environment, but also to control energy consumption and its impact on the environment. Comfortable buildings, energy efficiency, and positive energy buildings are all current issues that require knowledge of the basic principles of sustainable development in buildings. Moreover, understanding the values that characterize materials is essential today to choose products wisely from a technical and economic point of view. This work proposes to articulate them by focusing on Functionally graded material (FGM) as a design tool. Thus, it seeks to contribute to convert the concept of gradient into reality with accuracy and precision thanks to the manufacturing processes based on the new technology.

Published: January 2024

Abstract
The aim of the study in this paper is to examine the effects of investment in research and development activities of the manufacturing industry on the innovativeness in economy of the Republic of Serbia, and to draw conclusions in which direction further investments should be managed, bearing in mind that the importance of the processing industry for the overall economy has been growing from year to year. The comparative analysis shows the movement of the basic indicators of the manufacturing industry sector, as well as the movement of three basic indicators of the innovativeness in economy of the Republic of Serbia: GII (Global Innovation Index), GCI (Global Competitiveness Index) and SII (Summary Innovation Index). Based on the application of regression and correlation analysis, a weak contribution of gross domestic expenditures for research and development in the manufacturing industry to the improvement of the innovativeness in economy of the Republic of Serbia can be seen. On the other hand, a strong connection was established between the total gross domestic expenditures for research and development (at the level of the economy) and indicators of economic innovation, which indicates the need to restructure research and development expenditures in the direction of the manufacturing industry, with the aim of its greater contribution to the innovation of the overall economy. The progress of the economy of the Republic of Serbia viewed through the ranking and points of the used indicators of innovation can be attributed to investments in research and development activities in the area of other sectors of the economy, which can be the subject of some future research.

Abstract
Blue spruce (Picea pungens) has been planted in urban greenery as an ornamental tree in central Europe for more than 150 years. We investigated whether this nonnative spruce is a convenient habitat for ladybirds (Coleoptera, Coccinellidae). In 2021 and 2022, adults and larvae were sampled in four towns in Slovakia at monthly intervals throughout the growing season, from April to October. We recorded adults of 27 species and larvae of 11 ladybird species. Conifer specialist ladybird species predominated both in adult and larval communities (adults – 9 species, 85.2% of all individuals; larvae – 7 species, 92.1% of all individuals). Exochomus quadripustulatus and Aphidecta obliterata were the most common in adult (31.8% and 33.5% of all individuals, respectively) and larval (57.5% and 25.1% of all individuals, respectively) communities. The most abundant generalist species was nonnative invasive Harmonia axyridis (adults – 5.6%, larvae – 6.8% of all individuals). Adults and larvae of ladybirds were more abundant on solitary trees than on trees growing in groups. Our results confirmed that blue spruce hosts rich ladybird communities and provides them shelter and food resources.

Abstract

Falcataria moluccana (Miq.) Barnaby & Grimes is an important species for forest plantation programmes in Malaysia and is widely used in the wood industry. However, its root interactions have not been widely investigated due to the limited methodologies and information about the root distribution of trees and crops in forest plantation and agroforestry systems. This study was conducted to determine the rhizotron-scale root interactions of F. moluccana at different tillage and nitrogen concentrations under four different treatments: control, tillage, fertiliser, and tillage with fertiliser. The rhizotron-scale experiment was conducted at a greenhouse where F. moluccana (Batai) seedlings were transplanted in transparent rhizotron tubes (onemetre-high transparent polycarbonate solid sheet) using topsoil and river sand to simulate natural growing conditions. Root Intensity (RI), Root Length Density (RLD), Specific Root Length (SRL), dried shoot bio-mass and root biomass were recorded. Root biomass and SRL were notably higher (25–50 cm depth) at 6 WAT (Weeks After Transplanting), and the shoot biomass (tillage + fertiliser) was significantly higher at 14 WAT. However, plants treated with different tillage and nitrogen concentrations showed no significant impact on the RI and RLD. Fertiliser treatment only, and tillage with fertiliser treatment, showed greater root distribution at the rhizotron scale. These findings contribute to forest plantation and natural forest rehabilitation efforts by helping optimise the soil resources within ecosystems for sustainable forest management.

Abstract
The village weaver (Ploceus cucullatus) is a common colonial nesting bird widespread throughout Sub-Saharan Africa. It is known to weave its nests from leaf strips from a variety of tree species (mainly coconuts trees, oil palm trees) associated with human settlement areas, grasses, and other available plants. In this regard, this bird was considered a pest for its impact on different economic activities. Although extensive literature is already available on the parasitic role of village weavers, there is still a lack of analytical data that outlines which tree species are used for nesting and in what proportion, as well as the related implications in terms of economic impacts. Here, we carried out the first comprehensive arrangement of trees used by this species for nesting in Southern Nigeria (West Africa), checking for possible different impacts on stakeholders. In April 2021, we searched for village weaver nesting in 95 sites in 77 communities from 24 local government areas in Southern Nigeria, during 14 field surveys. Within each site, we collected GPS coordinates and counted the number of active nests, nesting birds and occupied trees. We recorded a total of 5,776 nests and 2,140 birds in 94 plants belonging to 23 tree species selected for nesting. Oil palm (Elaeis guineensis; n = 45) was the most used tree species, as 2,990 (51.77%) nests and 873 (40.79%) birds were recorded. Our results indicate the preference for nesting on trees used by stakeholders belonging to agricultural (palm farmers), touristic (operators) and energy (gas flare stations) sectors with economic implications about the conflict with this pest species.

Going concern assessment: a literature review
Authors: Proho Mahir 
Published: January 2024

Abstract
This paper addresses a underlying assumption of financial statements: going concern assumption. The going concern assumption constitutes a foundational premise presuming that the entity will conduct its operations in the forthcoming period (at least 12 months) without significant risk of business interruption. The primary objective of financial reporting is to provide information regarding the entity's financial position and performance to diverse users. Management is obligated to apprise users, and auditors are tasked with scrutinizing the assertion that the entity will continue its operations for a period exceeding 12 months. This paper meticulously examines the regulatory framework grounded in International Financial Reporting Standards and International Standards on Auditing. It particularly scrutinizes the role and significance of auditors in assessing the going concern assumption, encompassing an analysis of factors influencing the auditor's opinion on the going concern assumption and addressing criticisms directed at auditors. Furthermore, the paper explores past experiences in developing models for evaluating going concern assumptions, potentially aiding forensic accountants in uncovering irregularities in financial statements, given the correlation between a heightened bankruptcy risk and fraudulent activities.
Do Local Political Elections Affect Daily Stock Returns? Evidence from the Republic of North Macedonia's MBI10 Index
Authors: Deari Fitim , Koku Paul Sergius 
Published: January 2024

Abstract
Even though “all politics” are supposedly “local”, as reportedly said Tip O’Neil, the majority of studies on the link between politics and finance focused on presidential elections. This argues that overlooking local elections could result in a gap in the literature, thus it focused on the effect of the 2021 local elections on the stock market in the Republic of North Macedonia. The results could not reject the null hypothesis that local elections did not have any statistically significant effect on the stock prices as only 10% of the stocks traded experienced significant abnormal returns during the election period.

This study is entitled Commissive Illocutionary Acts in the American Comedy Movie Entitled: Home Alone. It focuses on a branch of speech act namely illocutionary acts, in particular to commissive and its types. The aims of this study are to identify the types of commissive illocutionary acts used by the characters in the movie and analyze the context of situation that supports the utterances which contain commissive illocutionary acts in the movie entitled Home Alone. The data of this study is taken from the American comedy movie entitled Home Alone (1990). The method used to collect the data in this study is the documentation method. The movie was watched repeatedly and the utterances was noted using note-taking technique. The descriptive-qualitative method was applied in analysing the data. In presenting the data, this study used the informal method which presented the data in the form of sentences. This study used the theory of Commissive Illocutionary Acts proposed by Searle (1969) and the theory of Context of Situation proposed by Holmes (2013); both theories were used in an attempt to answer the problems of this study. The findings of this study shows that there were forty-two utterances which are categorized under the types of commissive illocutionary acts, namely; promise, threat, refusal, intend and promise to do something, and offer to do something. Refusal type of commissive illocutionary acts is the most frequent one found in the analysis. Meanwhile, the context of situations are indeed beneficial to support the use of commissive illocutionary acts in Home Alone movie.

Authors: Utami Christa Dyah , Wardana Rudi , Fiqih Slamet Yohanas 
Published: January 2024

Tanaman talas merupakan tanaman umbi - umbian yang dapat dijadikan sebagai bahan pangan alternative selain beras. Adapun yang menjadi penyebab produksi rendah ialah keterbatasan lahan, kelangkaan bibit dan pertumbuhan yang relatif lama. Oleh karena itu dapat dilakukan penelitian dari anakan talas untuk melakukan perbanyakan vegetative dengan penambahan hormon auksin dan lama perendaman. Tujuan dari penelitian ini ialah untuk mengetahui respon pertumbuhan dan perkembangan bibit tanaman talas (Colocasia esculenta) dengan perendaman bibit menggunakan hormon auksin. Penelitian ini menggunakan metode RAK (Rancangan Acak Kelompok) dengan 6 taraf dan 4 kali ulangan. Pada konsentrasi 350mg/liter air yaitu: P0 kontrol, P1 1 jam, P2 1,5 jam, P3 2 jam, P4 22,5 jam, P5 3 jam. Jika pada perlakuan menyatakan berbeda nyata maka dilanjutkan dengan uji lanjut BNT 5%. Hasil penelitian menunjukkan Variabel perendaman bibit tanaman talas berpengaruh nyata pada pengamatan tinggi tunas, diameter batang, jumlah daun dan waktu munculnya tunas, akan tetapi pada variabel jumlah akar dan panjang akar berbeda tidak nyata. Hal tersebut karena beberapa faktor seperti variabel yang bebeda nyata diakibatkan karena adanya penambahan hormon auksin indole-3-acid (IAA) dan lama perendaman serta variabel yang berbeda tidak nyata terjadi Karena faktor eksternal yaitu media tanam dan proses pencabutan tanaman dari media tanam.

Published: January 2024

Kelompok tani Argopure Walida mengolah kopi dari cherry bean (CB) menjadi green bean (GB) dengan kategori spesialti, premium, dan komersil. Produk ini diolah dengan cara Natural, Hidrohoney, Anaerobic/Lactic, dan Carbonic Maceration (CM). Penelitian ini bertujuan untuk menghitung kelayakan usahanya dari produk masing – masing dari segi kelayakan bisnis. Metode penelitian ini menggunakan Net Presents Value (NPV), Break Event Point (BEP), Pay Back Period (PBP), dan Internal Rate Return (IRR). Observasi langsung, pencatatam jumlah bahan masuk dan keluar melalui pengumpulan data primer dan sekunder. Kemudian, telah didapatkan bahwa nilai NPV tidak menghasilkan angka negatif, NPV paling rendah > Rp 9jt; pada produk jenis komersil pengolahan hidrohoney, sedangkan angka NPV tertinggi pada pengolahan Anerobic dan CM > Rp 8M. Saat ini kelompok tani menggunakan energi listrik, bahan bakar bersumber dari energi fossil. Belum tersedia unit digester untuk menghasilkan energi alternatif (biogas), atau dengan solar panel. Disimpulkan meskipun nilai NPV masuk kategori layak secara bisnis, namun jika diasumsikan nilai IRR 15% masih ada produk Natural dan Hidrohoney pada kategori premium dan komersil masing – masing IRR 14% dan 13%. Maka asumsi 15% dianggap kurang, tetapi bila dilihat produk spesialti, premium, dan komersil dengan olahan tertentu mendapatkan estimasi IRR antara 17%-20%.
