daily calorific intake for countries across the globe. Wheat crops are attacked by a diverse range of herbivorous invertebrates (pests) that cause significant yield loss. It is anticipated that yield loss caused by pests will increase in response to a changing climate. Currently, these pests are primarily controlled using pesticides, however there is an increased need for more sustainable pest management solutions. Economic thresholds represent one avenue that can support the sustainable management of pests. Briefly, thresholds are the number of pests above which there is sufficient risk of yield loss. Here we review the economic thresholds and prediction methods available for sustainable pest management in wheat. We focus on five economically damaging pests affecting wheat crops in the UK and Europe. For each we highlight the key period of crop risk to pest attack, identify economic thresholds, and provide an overview of current decision support models that can help estimate crop risk and advise sustainable pest management; we end by proposing areas for future improvement for each pest. Furthermore, we take a novel approach by discussing economic thresholds and their applications to sustainable pest management within the context of crop physiology and the capacity for crops to tolerate pest damage, a consideration that is often overlooked when developing pest management strategies. We use the stem-boring pest, the gout fly, as a case-study and use the economic injury level equation to conduct a theoretical assessment of the appropriateness of the current gout fly threshold. This theoretical assessment indicates that wheat crops can tolerate greater gout fly damage than currently considered, and shows that by incorporating crop physiology into sustainable pest tolerance schemes we can work towards developing more appropriate physiological-based pest thresholds.

Most unprotected biodiversity is found outside state-owned protected areas, so developing effective conservation initiatives on privately and communally-owned land is critical. Conservationists have a long history of working with these landowners and their actions can be divided into two broad categories. The first is where they agree to take over responsibility for management, either by buying the land or agreeing on long-term leases. The second is where they “rent” the land for conservation and pay people to manage their land appropriately, often through agri-environment schemes. However, we still know relatively little about the effectiveness of these two approaches. Here we use an agent-based modelling approach to investigate the biodiversity outcomes over time of different land acquisition scenarios, based on varying buying and renting budgets and different levels of landowner willingness to engage with the conservation authority. We found that buying land always led to better conservation outcomes, with biodiversity scores being 23.4 times higher when 100% of the budget was for buying compared to when 100% of the budget was for renting. This was mostly because buying land ensured it was managed in perpetuity, allowing the biodiversity value of each land parcel to increase over time. We also found that land-owner willingness to sell or rent their land had a large impact on results, with biodiversity scores varying by 28 times depending on the level of support. Our modelling system will next be used to incorporate more sophisticated measures of biodiversity value and investigate other scenarios for developing ecological networks on privately-owned land, such as longer-term rental agreements and conservation stewardship agreements. In this way we hope to guide future conservation policy to develop large-scale conservation areas in England and inform global strategies that account for biodiversity and stakeholder preferences when designing ecological networks.
Exploring Scrotal Leiomyomas, Unraveling the Mysteries of a Rare Tumor: A Case Report
Authors: Sana Ahuja Sana , Verma Pooja , Aziz Khan Adil , Zaheer Sufian
Published: January 2024

Leiomyomas, originating from smooth muscle cells, are common in the uterus but rare in the scrotum, presenting a clinical challenge. Scrotal leiomyomas, first described in the 19th century, are characterized by benign pathology from the subcutaneous dartos muscle. We present two cases of middle-aged males with scrotal leiomyomas, detailing clinical presentations, histopathological findings, and immunohistochemistry results. The first involved a 48-year-old with a painless scrotal lump, excised to reveal well-circumscribed smooth muscle bundles. Immunohistochemistry confirmed vimentin, desmin, and smooth muscle actin (SMA) positivity, consistent with scrotal leiomyoma. The second case featured a 25-year-old with a painless scrotal swelling, histologically matching the features of scrotal leiomyoma. Accurate diagnosis is crucial for guiding appropriate management strategies. Clinicians often employ a combination of clinical evaluation, imaging studies, and histopathological examination to confirm the presence of scrotal leiomyomas. Ultrasound remains a valuable tool for assessing the size, location, and vascularity of the tumor, aiding in the formulation of a differential diagnosis. Definitive diagnosis, however, relies on histological examination, which typically reveals spindle-shaped smooth muscle cells arranged in interlacing bundles.

Authors: Baris David Jefferson , Heruwasto Ignatius
Published: January 2024

TikTok represents a new form of marketing communication technology due to its features and attributes. However, despite its ability to share brands’ viral content, scant research has examined TikTok as an advertising vehicle and its implications for viral advertising campaigns. Drawing on the Elaboration Likelihood Model and the concept of self-relevance, the present study explores the impact of perceived personalization and auhenticity of TikTok content on perceived convenience, viral behavioral intentions and purchase intention. The results show that the personalization of TikTok content is negatively related to perceived convenience and authenticity of TikTok content is positively related to perceived convenience. Overall, the results of this study provide new insights and practical implications for both content creator and advertiser sides.

Unlocking the Path to International Expansion: Investigating the Impact of Managerial International Experience on SME Internationalization
Authors: Fernando, Ph.D. Agus
Published: January 2024

This study explores the influence of a manager's international experience on small and medium-sized enterprises' (SMEs) internationalization. Contrary to common beliefs, we challenge the notion that international experience is the primary driver of firm internationalization. Using a research model and empirical data from SME managers, we find that a manager's aggressiveness in international markets plays a pivotal role in determining the degree of internationalization achieved by their SME. Aggressiveness in seeking opportunities emerged as a crucial factor for successful internationalization. Additionally, the manager's perception of risk associated with international expansion significantly impacts their level of aggressiveness. Managers with lower risk perceptions are more inclined to pursue international opportunities assertively. On the other hand, a manager's international experience directly affects their ability to recognize opportunities and develop confidence in international markets, driving aggressive behaviors. These findings challenge conventional assumptions and emphasize the importance of a proactive approach to international expansion. The study contributes to a deeper understanding of the complex relationship between a manager's international experience, aggressiveness, and SME internationalization. We encourage future research to further investigate the multifaceted process of international entrepreneurship, offering new perspectives to enhance SME success in global markets.

The Gebethner & Wolff company relations with Łódź at the turn of the 19th and 20th centuries
Authors: Konieczna Jadwiga
Published: January 2024

The purpose of the study is to describe relations connecting the Gebethner & Wolff editing bookshop with Łódź at the turn of the 19th and 20th centuries. The company established in 1857 in Warsaw opened in Łódź, in 1890, the warehouse of grand pianos, pianos and harmoniums, as well as a storehouse of notes. In further years, agencies selling periodicals – “Kurier Codzienny” (1893) and “Tygodnik Ilustrowany” (1896) published by Gebethner & Wolff also commenced their activities. Both the shop and the agencies played a significant role in the integration of the music and the journalistic environment in Łódź. In 1898 a bookshop was opened; however, it was sold to Rychliński & Wegner company in 1901. The next Gebethner & Wolff bookshop, established in 1912, conducted its activity until the beginning of the World War II. It offered mainly literature from a native publishing house, as well as quality foreign-language publications. During World War I, the bookshop organised special exhibits, the purpose of which was to promote Polish educational books.
The Gebethner & Wolff company has also undertaken activities that contributed to the popularisation of Łódź. It was the special number of “Tygodnik Ilustrowany” devoted to Łódź (1911 no. 19), as well as the information diary for 1914 called “Rocznik Łódźki Gebethnera & Wolffa” [Łódź Yearbook of the Gebethner & Wolff]. However, it was W. Reymont’s “Ziemia Obiecana” [The Promised Land], which had the greatest impact on shaping the image of the city upon the Łódka river. The initiative of appearance and publishing of the book was the effect of activity of Gebethner & Wolff.
The achievement of the above-mentioned, as well as other activities, became possible thanks to the participation of numerous persons connected with Łódź. They were, among others, booksellers: Robert Schwartzchultz, Juliusz Goźlinski, Stanislaw Miszewski, journalists: Wladyslaw Rowiński and Zenon Pietkiewicz, as well as the son of the company’s co-owner, Gustaw Wojciech Gebethner.

The overall aim of this study was to evaluate the reproductive performance of Oreochromis niloticus reared in ponds fed with periphyton and rice bran. It was carried out using a database resulting from an experiment carried out in the Gemena town hall, South Ubangi province in the Democratic Republic of Congo with Oreochromis niloticus fry fed on periphyton and rice bran. The methodological approach consisted of sampling the physico-chemical parameters of the pond water and the reproductive parameters, in particular the gonado-somatic ratio (GSR), the condition factor (K), fecundity and oocyte size. After analysis by pond category, it was found that the two treatments differed in terms of gonado-somatic ratio and condition factor. Treatment T1 is characterised by a relatively better value (RGS varying from 0.35 to 5.03 and K varying from 0.47 to 6.75) than treatment T0 (RGS varying from 0.34 to 3.91 and K varying from 0.20 to 3.26). The absolute fecundity of Oreochromis niloticus in the ponds with rice bran and those with periphyton varied respectively from 216-1504 and 279-1570. In contrast, the relative fecundity was 3.17-15.7 for the ponds with rice bran and 5.49-17.2 for the ponds with periphyton. These values correspond to total lengths of 11.6-18.1 Cm and 14.6-22.2 Cm, respectively. Oocyte diameter ranged from 0.95-2.00 mm, with an average of 1.63±0.05 mm, and from 0.89-2.15 mm, with an average of 1.59±0.05 mm, for females from ponds with rice bran and those with periphyton, respectively. At the end of this study, the results obtained showed that the females fed with periphyton showed a higher relative fecundity than those fed with rice bran. The data collected on the reproductive parameters indicate better reproductive performance in ponds fed with periphyton than in ponds fed with rice bran.

Authors: Rashid Gazi Mamunar , Hossain M M Touhid , Akhter Md Abdullah Elias , Mallik M A K
Published: January 2024

When temperature exceed 36 degrees with a large area and linger for minimum three or more days can be considered as heat wave (HW). In the Pre-monsoon, the sun ray drops down on the ‘Thar’ desert (India) and the foothill of the Himalayas vertically, the area makes a hot-tempered zone. That is why, these regions produce a trough of low and there is a possibility to advect temperature towards Bangladesh. The south/south westerly wind carries a high amount of moisture over Bangladesh. The heat capacity of moisture is higher than that of dry air. Solar insulation, temperature advection and moisture incursion are three main phenomena that are responsible for HW condition. Veering is also responsible for especially severe and very severe HW conditions. The present study is accompanying with all category’s frequency of heat wave days (HWD) and HW for the Pre-monsoon (March to May) over most of the stations (34) of Bangladesh for the period 1990-2019. Microsoft excel, Surfer and Arc GIS software have been used for data calculation, however, linear trend analysis and Mann-Kendall test have been used to draw the trend of HW frequency. The highest numbers of HWD are found in Jashore (30.9 days) of all types of events whereas the highest frequencies of HW are found in Rajshahi (4.2333) during pre-monsoon season. The lowest numbers of frequency of HWD and HW, both are found at Chattogram. April is the hottest month in Bangladesh. On the basis of frequency of HWD, the obtained highest hot places are Jashore, Chuadanga, Rajshahi, Ishurdi and Satkhira. while in Kutubdia and Teknaf, no HW is found at all. Among 30 years, 2014 is found the hottest year and 2018 is the recorded lowest hot year. By Mann-Kendall test, the HW trend of M. Court, Mongla, Patuakhali and Chandpur have indicated positive significant value, and Mymensing station has given only negative significant value. From spatial distribution, it shows the hottest areas which are south western and middle-western parts of Bangladesh.

Effects of Heat Generation and Chemical Reaction on Time-Dependent MHD Natural Convective Transport Past in a Vertical Perforated Sheet
Authors: Pk Md Abu Bkar
Published: January 2024

This investigation focused on the impacts of heat production and chemical reaction on time-dependent MHD-free convective transport via a vertical permeable sheet. The ODEs are obtained by transforming the governing PDEs using similarity transformations. With the assistance of MATLAB software, the shooting technique is utilized to numerically resolve the non-dimensional governing equations with boundary conditions. The role of emerging non-dimensional parameters or numbers like the Schmidt number , heat generation parameter (Q), Prandtl number , and chemical reaction parameter (Kr) on fluid temperature, velocity, and concentration were discussed within the boundary layer. The results show that temperature and fluid motion are improved by raising the heat generating parameters. On the contrary, as the chemical reaction value goes up, the fluid velocity and concentration do as well.

The bryoflora of the Zacharovana Dolyna Reserve (the Ukrainian Carpathians): species diversity and taxonomic structure
Authors: Sadygov Rostyslav , Felbaba-Klushyna Lyubov
Published: January 2024

Zacharovana Dolyna is a Ukrainian national geological reserve that was established in 1978. In 2009, it formed the basis for establishing the National Nature Park Zacharovany Krai, and now it is the most interesting part of the park regarding its environmental diversity. Investigations of the biodiversity of this park remain at the initial stage, and data on bryophytes are not available so far. We identified 114 bryophyte species, including 45 species that were proven new to the Volcanic Carpathians. We performed a taxonomic analysis of the bryoflora and clarified that Mniaceae (10 species), Polytrichaceae (8 species), and Brachytheciaceae (8 species) were the species richest families; the last one mentioned belongs to the three species richest families of the Ukrainian Carpathians. Most species of the families Mniaceae, Polytrichaceae and Brachyteciaceae prefer overmoistened ecotopes prevailing in the studied area, including wet rocks and stones along streams. A special feature of the Reserve is that a significant percentage of the species were found on stony substrates. The bryophyte flora documented here also includes the species of conservation concern. Pseudohygrohypnum fertile is considered vulnerable, endangered, or rare in many European countries, while Dicranum viride is the Bern Convention species. Neckera pennata is especially rare for Zakarpattia and is a vulnerable species listed in the Ukrainian Red List of Bryophytes. We registered a high species diversity of bryophytes in a relatively small area of the Zacharovana Dolyna Reserve due to the high diversity of potential bryophyte substrates and microhabitats.

Tuberculosis (TB) is a deadly infectious disease that threatens the world. Indonesia currently ranks second highest in the world with TB caseload. TB poses a very complex problem both in terms of medical, as well as social, economic, and cultural aspects. Drug-resistant tuberculosis (DR-TB) cases in Sumenep district have been increasing over the past five years. Risk factors for DR-TB cases in Sumenep District are mostly treatment dropouts. The recorded number of DR-TB until October 2023 was 39 people and there were 2 non-compliant patients / dropouts. This will certainly be a public health threat, considering that TB is a contagious disease. An effective strategy in strengthening the response to DR-TB in Sumenep District is community empowerment through the involvement and role of DR-TB survivors. The involvement of survivors of DR-TB is very important in improving treatment adherence through sharing good experiences, education and motivation. This activity is carried out through advocacy methods (audiences), commitment formation meetings and organization and capacity building. This program was carried out for 2 months from planning, implementation and reporting. The results of the activities: a) the hearing was addressed to the P2KB Sumenep Health Office and the Bhanu Yasa Sejahtera Foundation (YABHYSA) Sumenep Branch and RSUD dr. H. Moh Anwar Sumenep. b) SAKERA formation meeting through socialization, discussion, testimony and commitment formation.  93.33% of participants agreed to form a survivor organization called SAKERA; c) SAKERA institutional capacity building activities. The method used was socialization, discussion and assistance in document preparation. This objective resulted in the main organizational documents, namely by-laws, organizational structure and standard operating procedures (SOP) for SAKERA activities

Al-Qur'an and Al-Hadith have stipulated the obligation to consume halal and good food. Traditionally, food is produced from raw materials involving relatively simple processes. However, in the modern era, food products are made through complex processes involving food additives and processing aids that can change their halalnes. The Law number 33 of 2014 about Halal Product Assurance has stipulated that product distributed and traded in Indonesia must be halal certified. SMKN 1 Menggala Lampung has been able to produce various food products processed from fish, vegetables, and fruits. However, these products have not been certified halal. One of the obstacles faced is the lack of understanding of the process and regulations of halal certification such as the use of a new halal logo, self-declare, and Free Halal Certification Program facilitated by BPJPH (Halal Product Guarantee Organizing Agency). The solution offered is training in the production of halal and thoyyib food products to prepare for halal certification. Training activities begin with coordination activities and pre-test. The training materials consists of two parts: Halal Food Production (The importance of Halal Certification, Halal Certification Procedures, and Introduction to Halal Materials) and Thoyyib Food Production (Good Manufacturing Process). Participants taking part were 30 participants consisting of the principal, 19 subject teachers, and 10 students. After both trainings, all participants take post-test to measure the effectiveness of the training. The results show that 86% participants achieved higher scores. In general, the participants' understanding has improved. It may be concluded that the training was conducted successfully and achieved targets according to plan.

Street food, also known as "street food", is food and drink prepared and sold by street vendors in streets and other public gathering places. These foods are directly eaten and consumed without any additional processing or preparation. Street vendors are essential for providing food in cities, but they often face hygiene and sanitation issues. The objective of this study was to educate the impact on hygiene and sanitation awareness and practices in street vendors around Jalan Sutorejo, Surabaya. The results showed that after this activity, street vendors have a better understanding of food sanitation and hygiene. This study shows that improving street vendors' food hygiene and sanitation awareness and practices is very important. The findings can be the basis for building a broader program to help street vendors around Jalan Sutorejo, Surabaya, maintain the hygiene and safety of their food products.

Red dragon fruit is one of the fruits that is often consumed by the Indonesian people because it is rich in properties and benefits. In addition to the fruit, red dragon fruit skin can also be used as a natural colorant in food and cosmetics. One of the beneficial compounds contained in the skin and flesh of red dragon fruit is antioxidant. This study aims to determine the differences in antioxidant activity and non-specific parameters of red dragon fruit skin and flesh extracts. The samples used are skin and flesh of red dragon fruit, in addition to comparing fresh samples and dried simplisia of each skin and flesh, dried simplisia samples from each skin and flesh. Method extraction method used in this study is reflux method with 70% ethanol solvent. Antioxidant activity was determined by IC50 value. From the IC50 calculation, it was found that red dragon fruit peel extract with fresh samples and dry simplisia included strong antioxidants while antioxidants in red dragon fruit flesh were lower with weak antioxidant activity. The difference in the use of simplisia also affects the antioxidant activity of the extract, extracts using dry simplisia have higher antioxidant activity than extracts using fresh samples. While in the test of non-specific parameters of the extract there is no significant effect.
Preserving Absolute Simultaneity with the Lorentz Transformation
Authors: Colombo Attilio
Published: January 2024

In this work it is shown how absolute simultaneity of spatially distinct events can be established by means of a general criterion based on isotropically propagating signals and how it can be consistently preserved also when operating with Lorentz-like coordinate transformations between moving frames. The specific invariance properties of these transformations of coordinates are discussed, leading to a different interpretation of the physical meaning of the transformed variables with respect to their prevailing interpretation when associated with the Lorentz transformation. On these basis, the emission hypothesis of W. Ritz is then applied to justify the outcomes of the Fizeau experiment, thanks to the introduction of an additional hypothesis regarding the influence of turbulence on the refractive index of the moving fluid. Finally, a test case to investigate the validity of either the Galilean or the Relativistic velocity composition rule is presented. Such test relies on the aberration of the light coming from celestial objects due to the motion of the observer, and on the analysis of the results obtained by applying the two different formulas to process the data of the observed positions, as measured in the moving frame, in order to determine the actual un-aberrated location of the source.
Note for the P versus NP Problem
Authors: Vega Frank
Published: January 2024

$P$ versus $NP$ is considered as one of the most important open problems in computer science. This consists in knowing the answer of the following question: Is $P$ equal to $NP$? It was essentially mentioned in 1955 from a letter written by John Nash to the United States National Security Agency. However, a precise statement of the $P$ versus $NP$ problem was introduced independently by Stephen Cook and Leonid Levin. Since that date, all efforts to find a proof for this problem have failed. Another major complexity class is $NP$-complete. It is well-known that $P$ is equal to $NP$ under the assumption of the existence of a polynomial time algorithm for some $NP$-complete. We show that the Monotone Weighted 2-satisfiability problem (MW2SAT) is $NP$-complete and $P$ at the same time.
