Generalized and modified orders of growth for Dirichlet series absolutely convergent in a half-plane
Authors: Filevych P. V. , Hrybel O. B. 
Published: June 2024

Let $\lambda=(\lambda_n)_{n\in\mathbb{N}_0}$ be a non-negative sequence increasing to $+\infty$, $\tau(\lambda)=\varlimsup_{n\to\infty}(\ln n/\lambda_n)$, and $\mathcal{D}_0(\lambda) $ be the class of all Dirichlet series of the form $F(s)=\sum_{n=0}^\infty a_n(F)e^{s\lambda_n}$ absolutely convergent in the half-plane $\operatorname{Re}s<0$ with $a_n(F)\not=0$ for at least one integer $n\ge0$. Also, let $\alpha$ be a continuous function on $[x_0,+\infty)$ increasing to $+\infty$, $\beta$ be a continuous function on $[a,0)$ such that $\beta(\sigma)\to+\infty$ as $\sigma\uparrow0$, and $\gamma$ be a continuous positive function on $[b,0)$. In the article, we investigate the growth of a Dirichlet series $F\in\mathcal{D}_0(\lambda)$ depending on the behavior of the sequence $(|a_n(F)|)$ in terms of its $\alpha,\beta,\gamma$-orders determined by the equalities$$R^*_{\alpha,\beta,\gamma}(F)=\varlimsup_{\sigma\uparrow0}\frac{\alpha(\max\{x_0,\gamma(\sigma)\ln\mu(\sigma)\})}{\beta(\sigma)},$$$$R_{\alpha,\beta,\gamma}(F)=\varlimsup_{\sigma\uparrow0}\frac{\alpha(\max\{x_0,\gamma(\sigma)\ln M(\sigma)\})}{\beta(\sigma)},$$where $\mu(\sigma)=\max\{|a_n(F)|e^{\sigma\lambda_n}\colon n\ge0\}$ and $M(\sigma)=\sup\{|F(s )|\colon \operatorname{Re}s=\sigma\}$ are the maximal term and the supremum modulus of the series $F$, respectively. In particular, if for every fixed $t>0$ we have $\alpha(tx)\sim \alpha(x)$ as $x\to+\infty$, $\beta(t\sigma)\sim t^{-\rho}\beta(\sigma)$ as $\sigma\uparrow0$ for some fixed $\rho>0$, $0<\varliminf_{\sigma\uparrow0}\gamma(t\sigma)/\gamma(\sigma) \le\varlimsup_{\sigma\uparrow0}\gamma(t\sigma)/\gamma(\sigma)<+\infty$,$\Phi(\sigma)=\alpha^{-1}(\beta(\sigma))/\gamma(\sigma)$ for all $\sigma\in[\sigma_0,0)$,$\widetilde{\Phi}(x)=\max\{x\sigma-\Phi(\sigma)\colon \sigma\in[\sigma_0,0)\}$ for all $x\in\mathbb{R}$, and $\Delta_\Phi(\lambda)=\varlimsup_{n\to\infty}( -\ln n/\widetilde{\Phi}(\lambda_n))$, then:
(a) for each Dirichlet series $F\in\mathcal{D}_0(\lambda)$ we have$$R^*_{\alpha,\beta,\gamma}(F)=\varlimsup_{n\to +\infty}\left(\frac{\ln^+|a_n(F)|}{-\widetilde{\Phi }(\lambda_n)}\right)^\rho;$$
(b) if $\tau(\lambda)>0$, then for each $p_0\in[0,+\infty]$ and any positive function $\Psi$ on $[c,0)$ there exists a Dirichlet series $F\in\mathcal{D}_0(\lambda)$ such that $R^*_{\alpha,\beta,\gamma}(F)=p_0$ and $M(\sigma,F)\ge \Psi(\sigma)$ for all $\sigma\in[\sigma_0,0)$;
(c) if $\tau(\lambda)=0$, then $(R_{\alpha,\beta,\gamma} (F))^{1/\rho}\le (R^*_{\alpha,\beta,\gamma}(F))^{1/\rho}+\Delta_\Phi(\lambda)$ for every Dirichlet series\linebreak $F\in\mathcal{D}_0(\lambda)$;
(d) if $\tau(\lambda)=0$, then for each $p_0\in[0,+\infty]$ there exists a Dirichlet series $F\in\mathcal{D}_0(\lambda)$ such that $R^*_{\alpha,\beta,\gamma}(F)=p_0$ and $(R_{\alpha,\beta,\gamma}(F))^{1/\rho}=(R ^*_{\alpha,\beta,\gamma}(F))^{1/\rho}+\Delta_\Phi(\lambda)$.

A Discursive Concern on Pollution in Kathmandu Valley and Its Consequences
Authors: Gurung Raj Kumar 
Published: June 2024

I find this dialogue meaningful here.
A gentleman: Hello sir, what are the three remarkable things you find in Nepal?
Tourist: Oh! I find that every man is a doctor; every man is a politician; and Kathmandu is a big toilet. (Source: Personal talk)
“Kathmandu is a big toilet”. What a joke! What a satire! Is Kathmandu so? Interesting! This paper explores the discursive concern about pollution in Kathmandu, the study area, and its consequences. The previous mayors of Kathmandu Metropolitan City (KMC) solved this problem partially. The city dwellers could not have breathed fresh air for about two decades despite several attempts by environmentalists and awareness articles written by national and international writers. The findings of the study show that Kathmandu is one of the dirtiest cities in the world and there is a possibility of lung cancer, respiratory problems, and many more. These adverse impacts of pollution are beyond prediction. This metropolitan city now has a new young energetic Mayor, Balendra Shah. The Kathmanduites have woven a big dream over him. I think he will come up with good new plans to address the discursive concern on the pollution problem. There are limited scholarly research papers published on this issue. The study sheds light on, “When will the day of crystal clean Kathmandu come?” and attempts to make the KMC people commit to strictly monitoring waste management. Pollution means the natural environment deterioration: air pollution, water pollution, land pollution, light pollution and noise pollution. This paper focuses on the strict implementation of strict rules to curb the pollution crisis. This provision mitigates the pollution problem so that people breathe fresh air and enhance the environmental literature. The mixed methods of cause and effect, document analysis and qualitative research were used in the study.

Authors: Dharma  Canti Distca Putri , Lestari Vidyahayati Indah , Natania Renata Purnomo Brigitta 
Published: June 2024

Background: The main bacteria involved in the formation of dental caries is Streptococcus mutans (S. mutans). One approach to reduce the growth of S. mutans bacterial colonies is by brushing teeth with toothpaste containing antibacterial agent. The commonly used antibacterial agent is chlorhexidine, which is the gold standard chemical in reducing the colonization of S. mutans bacteria and other oral biofilms. However, over time, it causes various side effects, thus necessitating the search for alternative natural ingredients. One of potential ingredient with antibacterial agent is the Spirulina platensis, which contains secondary metabolites known to inhibit the growth of pathogenic bacteria. Thus, Spirulina platensis can be added to toothpaste as an antibacterial agent. Method: This study employed an experimental laboratory design with a post-test-only control group design. The study consisted of 7 treatments with 5 replications. Antibacterial activity was tested using the agar diffusion method by observing the average diameter of the inhibition zone formed. Data were analyzed using parametric one-way ANOVA. Discussion and Results: In this study, toothpaste with Spirulina platensis extract at concentrations of 0.25%, 0.5%, 1%, 2%, and 3% can inhibited the growth of S. mutans with average inhibition zone diameters of 20.4 mm, 20.8 mm, 21.8 mm, 22.3 mm, and 22.7 mm. The one-way ANOVA parametric test results showed a value of p0.05, indicating a significant difference in the antibacterial activity of S. mutans in all treatment groups. Conclusion: Toothpaste formulations with Spirulina platensis extract have antibacterial activity against S. mutans bacteria.
Anatoly Vasiliev’s Theatre. Semiology of Continuity and the Way to a New Type of Theatrical System
Authors: Perevalov A. I. 
Published: June 2024

Introduction. The article provides a general description of Anatoly Vasiliev’s theatrical method, discussing the essence of methodological and philosophical breakthroughs in the future of Russian and world theaters, and, in this context, the continuity of the main tenets of Stanislavsky’s system.Methodology and sources. The article compares two theatrical concepts, two methodological, philosophical, and historical approaches of Russian and World Theatres: Stanislavski’s system and Vasiliev’s method. It determines the semiology of continuity and features of a new approach to the development of dramatic art.Results and discussion. The article highlights the elements of the Stanislavsky system present in Anatoly Vasiliev’s method, aiming to derive an algorithm for utilizing new opportunities based on established systems and techniques for training modern actors. The article's conclusions are drawn from five years of experience (since 1988) with the Vasiliev method, gained through direct contact with the master while collaborating on texts by Plato, Oscar Wilde, Fyodor Dostoevsky, William Faulkner, Thomas Mann, Erasmus of Rotterdam, and Alexander Pushkin. As the article relies on introspective research followed by epistemological analysis, it maintains a subjective nature. It is the outcome of the author’s experience working within the Anatoly Vasiliev’ s School of Dramatic Art at the GITIS acting and directing course (1988–1993), and years of observation of the method’s evolution in working with Vasiliev's students, students of theater universities, and professional actors both in Russia and abroad.Conclusion. The article does not claim to precisely represent Vasiliev’s ideas and thoughts but rather reflects the author’s journey through the rehearsal process in Vasiliev’s theater, acknowledging the internal changes experienced by the author as an actor, director, and individual within the method. It abstains from making value judgments regarding the Stanislavsky system and Vasiliev’s method, instead highlighting the most distinctive features of the theatrical method, elucidating its philosophy, and emphasizing the unity between the Stanislavsky and Vasiliev systems.

Background: High blood sugar levels that exceed normal limits or commonly refered to as hyperglycemia, is an early symptom of diabetes mellitus.
Objectives: This study explored the effect of lemon (Citrus limon) extract on blood sugar levels and pancreatic b cell regeneration in alloxan-induced hyperglycemic mice (Mus musculus).
Method: This research is an experimental study using a post-test group. The sampling was carried out using a randomization method. By administering 125 mg/kg BW of alloxan, the sample was conditioned for hyperglycemia. The samples were divided into five groups: normal control, alloxan-induced control, and three treatment groups that received lemon extract with dosages of 100 mg/kg BW, 300 mg/kg BW and 500 mg/kg BW, respectively. Semiquantitative analysis was used to evaluate pancreatic damage.
Results: The results showed that lemon extract can decrease blood sugar levels. Histopathological imaging revealed a significant improvement in b cell distribution and decreased vacuolization in the Langerhans islets of mice administered lemon extract. No significant differences were observed among different dosages of lemon extract (p>0.05).
Conclusion: Our findings underscore the potential therapeutic benefits of lemon extract in managing blood sugar levels and promoting pancreatic b cell regeneration in alloxan-induced mice.

Embung adalah suatu bangunan konservasi air yang berbentuk kolam yang digunakan untuk menampung air hujan dan air limpasan sekitar untuk keperluan cadangan air pada saat musim kemarau. Tetapi embung dapat juga dikembangkan sebagai sarana kolam retensi untuk pengendalian banjir dalam skala kecil, diharapkan air hujan yang jatuh dikawasan pemukiman tersebut dapat ditampung di embung ini, sehingga kawasan ini dapat disebut sebagai kawasan zero runoff, dimana tidak terdapat limpasan air yang keluar ke hilir dari kawasan ini. DAS Cipamokolan bagian hulu tergolong tidak sering banjir, tetapi kejadian luar biasa terjadi pada bulan Maret 2018, dimana pada saat itu terjadi banjir bandang beserta lumpur yang menerjang pemukiman. DAS Cipamokolan sampai dengan titik tinjau ini luas DASnya sebesar 6,705 km2, berdasarkan analisa frekuensi curah hujan rencana adalah 10 tahunan sebesar 129,7 mm dengan debit puncak banjir sebesar 32,084 m3/det, Rencana pengendalian banjir Cipamokolan ini adalah dengan membuat embung di hulu sehingga limpasan air ke arah hilir dapat dikurangi. Dan analisa reduksi banjir dihitung dengan menggunakan penelusuran banjir melalui embung/waduk dengan menggunakan software HECHMS 3.5. dan dapat mereduksi puncak debit banjir sebesar 7,60% sampai 34,76% dari debit puncak kondisi eksisting. Kapasitas alur sungai Cipamokolan di ruas ini adalah sebesar 28,681 m3/det. Dengan kapasitas sebesar ini, maka kondisi dengan adanya embung ini akan dapat menampung debit dengan kala ulang 10 tahun, dimana dengan adanya embung maka debit puncak banjir dari sebesar 32,084 m3/det dapat menjadi sebesar 24,441 m3/det. Sehingga dapat dikatakan bahwa dengan adanya embung ini kondisi zero run off masih belum bisa dicapai, tetapi debit puncak banjir dapat tereduksi, sehingga diharapkan dapat mengurangi dampak banjir yang mungkin terjadi.
