Published: September 2024

The current study explores the feasibility of using rice husk ash(RHA) as an additive in PPC (Portland Pozzolana Cement) concrete for rigid road pavement. The research investigates the impact of RHA on concrete’s strength parameters, specifically tensile, split tensile and compressive strengths. The conventional mix design method is applied for the controlled concrete, serving as baseline for designing mixes with varying percentage of RHA as a replacement for cement. The study examines five replacement levels: 5%, 7.5%, 10%, 12.5%, and 15%. Various curing durations are tested, including 3 days, 7 days, 28 days, and 56 days. The primary focus is to determine the optimal quantity of RHA as a cement replacement through experimental analysis. Key findings reveal that for compressive strength, the optimal replacement level is 10% RHA, while for flexural strength, the optimal replacement level is 5% RHA. These results underscore the potential of RHA to enhance concrete performance in road pavement applications when used judiciously as a partial substitute for cement.

Authors: C. Jayajothi  , Senthamilselvi M.M.
Published: September 2024

This study aims to explore the mechanism of Cr6+reduction (removal) in aqueous solutions using an adsorbent, specifically activated carbon (adsorbent) derived from Avervalanata stems. Through treatment with H3 PO4 , activated carbon, known as PAALC, was obtained. Batch experiments were conducted to assess the influence of various factors such as pH, dosage, contact time, initial ion concentration, and temperature. The findings indicated that the initial adsorption of Cr6+ions onto PAALC conforms well to the Langmuir isotherm model. Kinetic analysis revealed that the pseudo-second-order model best describes the equilibrium data, suggesting a rapid rate of Cr6+ion adsorption. Moreover, the study underscores the substantial potential of PAALC in effectively removing Cr6+ from water.

Authors: Pegu Bhaba Kumar , Bora Limpon , Engty Jyoti Prava , Kardong Devid
Published: September 2024

The study aims at screening, isolation, and characterization of naringinase enzyme producing bacterial strains from soil samples. In this study, 45 bacterial isolates were screened for naringinase activity, and among them, 20 bacterial isolates are found to be capable of naringinase production in liquid mineral medium. Bacterial isolate D1 exhibited the highest naringinase activity in liquid mineral medium. Based on the morphological, biochemical, fatty acid profile, and molecular characterization, bacterial isolate D1 was identified as Bacillus amyloliquefaciens. Impact of different submerged culture parameters were evaluated in different experimental conditions. The study revealed that 48 hrs of incubation periods, pH 6.0 and temperature 350 C is optimal for naringinase activity when the culture medium is supplemented with starch and yeast extract as carbon and nitrogen sources. Thus, it can be concluded that due to the potential naringinase activity of the strain Bacillus amyloliquefaciens D1, further the identifying strain may be used in citrus processing and bioprocess industries upon large scale field applications.

Is the Fama French model robust in the Chinese stock market?
Authors: Chen Hongxi
Published: September 2024

Many previous studies have analyzed the different stock return models in various segments of the Chinese stock market. This essay analyzes the Fama-French five factors and three factors model in the main board, the second board, and STAR market. It finds that the three-factor models are efficient in all three markets expect for the STAR market, while the five-factor model is inefficient in testing the second board market alone and overall efficient in testing the mixed market and the STAR market. Furthermore, it is also found that the MKT factors are the most significant contributors to the portfolio excess return in all six situations. The HML and SML factors also exhibit constant relations with the portfolio return. Besides, it is found that HML and SMB factors are not significantly correlated with the stock’s performance on the STAR market. Overall, the relative efficiency of Fama French's three and five-factor model in explaining these markets is proved. Investors can use these two models to analyze the stock return and earn profit in the next period, and policymakers can also employ this model to understand the market and decide suitable fiscal and monetary policies.

Authors: Zheng Zhenyu
Published: September 2024

This study sets out to unravel the complexities of digital transformation challenges faced by traditional enterprises in China, focusing on identifying the multifaceted barriers that impede their progress towards digitalization. Employing a comprehensive review of existing literature coupled with empirical evidence from typical enterprises, the research adopts a qualitative approach to explore the core barriers to digital transformation. The findings reveal that traditional enterprises face significant hurdles in their digital transformation journey, including high transformation costs, prolonged investment durations with uncertain outcomes, and a lack of necessary capabilities for effective digital adoption. However, by strategically combining core factors such as innovation ecosystems, technological infrastructure, and digital components, and placing substantial emphasis on cultivating an internal learning-oriented mindset, enterprises can navigate these challenges effectively. The study illustrates that fostering a learning orientation not only accelerates the application and dissemination of digital technologies but also encourages critical assessment of existing management practices, thereby facilitating the transformation of operations and expansion into new markets. The impact of this research lies in its contribution to both academic discourse and practical implementation, offering valuable insights and recommendations for business leaders and policymakers. By highlighting the critical components of digital transformation and identifying strategies to overcome prevalent obstacles, the study provides a roadmap for traditional enterprises striving to innovate and thrive in the digital age.
Study of College Counselor Team Building to Enhance College Students' Career Planning Education
Authors: Wen Huan
Published: September 2024

College students are under more pressure to find work as a result of the employment market's imbalance between supply and demand due to the economic structure's adjustment. This has resulted in a phenomenon known as "examination and editing fever" and "slow employment." Providing career planning instruction to college students is crucial in directing their professional growth. Nonetheless, domestic colleges and universities typically overlook issues such as the absence of research on localized education models, the paucity of professors, the reliance on counselors primarily for educational purposes, and other issues related to career planning education for college students. Additionally, there aren't enough counselors with professional experience to carry out vocational education; power is dispersed rather than concentrated, and the teaching effect isn't ideal. The impact of college students' vocational career planning education can be enhanced "from top to bottom," "from general to separate," "from inside to outside," and "from general to precise" by assembling a team of counselors and creating a team.

The results show that there is a high correlation between ESG rating scores and corporate performance. Companies that score higher on ESG indicators tend to perform better financially, indicating that a focus on sustainability and responsible business practices can drive value creation. In addition, detailed and in-depth disclosure of ESG information helps to enhance corporate value. These findings deepen the understanding of how ESG disclosure affects corporate performance and provide theoretical support for companies and investors who seek valuable guidance.
Le forme felici di Kafka (distorcere l’umano)
Authors: Salzani Carlo
Published: September 2024

L’articolo analizza e commenta una celebre frase che segna il saggio che Walter Benjamin dedicò a Kafka nel 1934 per il decimo anniversario della sua morte: notando come la distorsione sia il segno distintivo della scrittura kafkiana, Benjamin ne sceglie a emblema l’«omino gobbo» di una celebre filastrocca tedesca, concludendo però che esso «svanirà quando verrà il Messia, di cui un gran rabbino ha detto che non intende mutare il mondo con la violenza, ma solo aggiustarlo di pochissimo». Nella forma di questa scomparsa e di questo «aggiustamento» sta il senso della proposta messianica di Kafka: consiste esso in un raddrizzamento della gobba? O se no, che forma prenderà la redenzione?
Nietzsche’s Homo Natura and Biopolitics
Authors: Caldara Patrizio
Published: September 2024

The controversial figure of homo natura has recently been a central issue in Nietzsche’s studies. The debate regarding Nietzsche’s biopolitical character has taken homo natura to be a fundamental concept in order to assess his stand in political philosophy. In the following article several readings of homo natura will be presented and evaluated. The main thesis of this contribution is that this Nietzschean figure is best interpreted primarily in an “ethical” sense, namely, as a way of being and behaving. The political dimension is a consequence of this “ethical” posture and defies any easy biopolitical labeling. It is claimed that Nietzsche’s homo natura broadens the biopolitical discourse rather than taking place as one of its figures (as, e.g., Michel Foucault’s homo oeconomicus or Giorgio Agamben’s homo sacer) by explicitly addressing and overcoming the anthropocentric challenge that resides at the core of biopolitics. If we are right, then, depending on which homo natura’s interpretation we favour, we are left with a different categorization of Nietzsche’s political philosophy. Therefore, homo natura presents a cluster of questions that need to be addressed if we want to be able to fully grasp Nietzsche’s practical philosophy.
Il Kafka di Fellini
Authors: Bellini Manuele
Published: September 2024

In this essay, we focus mainly on Intervista (1987), a film set on the set of a film based on Kafka’s Amerika. Here Fellini seems to identify himself with Kafka, not for the purpose of portraying the Prague writer’s novel, deemed already «too visual», but on the contrary to talk about himself, about his own sentimental upbringing during his adolescence and his own way of filmmaking. The game of mirroring is complex and does not stop at the autobiographical level: it allows us to grasp the meaning of Fellini’s cinema, which is to grasp reality through the imagination, as Milan Kundera wrote. If we focus on the late Fellini, we can say that cinema is image and words are superfluous. Words tell, while the image shows. Words are tied to ideologies, to grand narratives, while the image is as free as the language of dreams, which Fellini is inspired by referring to Jung. Therefore, the Fellini film image is by no means a verisimilar representation; rather, it is a meta-image that uses kafkaesque poetics to speaks, with ironic levity, about the fate of cinema in the modern world, in which nightmare blends with reality, as the unfinished project Il viaggio di G. Mastorna shows.
Franz Kafka
Authors: Porro Mario
Published: September 2024

A recurring aspect of Kafka’s “anti-heroes” is hesitation, remaining stuck on the threshold, waiting in vain to be able to gain access. This is highlighted in an exemplary way by the parable that contains the meaning of the Trial, Before the Law: the countryman waits his whole life to be able to cross the door guarded by the guardian. The other parable of Hasidic inspiration, A Message from the Emperor, also presents a similar situation, albeit inverted: the message sent by the dying emperor cannot reach the “individual”, who nevertheless awaits it confidently, the continuity of the path does not allow the messenger to reach the goal.
In this impossibility of having access – to the Law, to the Truth, to existence, to birth or death, as in the case of the hunter Gracchus – we can read the condition of the foreigner of the Jew Kafka, the sense of exclusion from life developed by the authoritarian paternal upbringing, his refusal of a “normal” life – that of a public official and a husband. Many Kafkaesque characters thus live in a liminal situation, prisoners of the transition: the protagonist of The Castle waits in vain for his request to be accepted, he exhausts himself in an incessant questioning, in an interpretative effort which is a replica, in language and thought, of the inability to move and overcome obstacles.
De la convenientia latine à la convenance française du XVIIe siècle
Authors: Muceni Elena
Published: September 2024

The idea of convenientia was already conceptualised and exploited as a key notion in aesthetic reflection in classical Latin culture. But the term also belongs to other lexical domains, notably that of ethics, in which it has been originally adopted to indicate the form of a duty in relation to an order that transcends the subject. In this article, we explore the vicissitudes of this notion in French philosophy at a crucial linguistic and cultural turning point, the seventeenth century, when Latin was dethroned by the vernacular languages. Against this background of instability in the philosophical lexicon, we will focus on two authors who recovered and “adapted” the Latin concept of convenientia, contributing to redefine its meaning and value as convenance in French-language philosophy: Pierre-Sylvain Régis (1632-1707) and Nicolas Malebranche (1638-1715). The adoption of a comparative approach between these two authors, who were almost perfect contemporaries and whose works stand in the same Cartesian tradition, has a double advantage: it allows to grasp the particularity of the interpretations of the two authors while offering a “sample” that testifies to the echo and the role assigned to the notion of convenance in French philosophy at the end of the seventeenth century. The result of the reworking of this concept, particularly by Régis, leads to a rapprochement between the “ethical” and “aesthetic” meanings of convenance.

The intertwining of commercialization and culture is a complex process that shapes how society functions and evolves. Culture, with its multifaceted elements such as language, customs, values, and art, is a dynamic force that constantly interacts with the economic forces of commercialization. This paper deals with the study of " Impact of Commercialization on Our Culture: With Special Reference to Popular Indian Festivals," as commercialization has reshaped how we celebrate our festivals. One of the most noticeable impacts of commercialization is the commodification of festivals. Many festivals have become lucrative business opportunities to promote and sell their products. This is evident in the extensive marketing campaigns, sponsored events, and influx of consumer goods during festive seasons. While this has injected economic vitality into local markets and industries, it has also led to concerns about diluting the festivals' original cultural and spiritual essence.

Ada beberapa faktor yang menyebabkan peralatan lashing muatan di atas kapal sering menemui kendala, misalnya pengawasan yang kurang baik dalam proses pemuatan,komunikasi yang kurang baik antara pihak darat dan pihak kapal,mengenai pertukaran muatan,sehingga jumlah lashing material yang terbatas, dan mewajibkan semua pihak yang menangani peralatan lashing harus memahami prosedur bagaimana caranya pengikatan peti kemas yang baik dan benar, agar  mengurangi tingkat resiko kerusakan muatan di dalam peti kemas. Optimalisasi  menurut Kamus Besar Bahasa Indonesia ialah tertinggi, paling baik, sempurna, terbaik, paling menguntungkan, mengoptimalkan  berarti menjadikan sempurna, menjadikan paling tinggi,menjadikan maksimal optimalisasi bearti pengoptimalan. Tujuan penelitian yang dilakukan penulis  dimaksudkan  untuk :a.menganalisa penyebab deck rating belum melaksanakan perawatan lashing muatan sesuai prosedur dan alternatif pemecahannya.b. Untuk menganalisis penyebab peralatan lashing yang dibutuhkan tidak tersedia di kapal dan alternatif pemecahannya. Berdasarkan hasil penelitian secara langsung bahwa kurang optimalnya proses bongkar muat yang dilaksanakan di pelabuhan dikarenakan 1.Deck rating belum familiar dengan prosedur perawatan peralatan lashing muatan sehingga tidak melaksanakan perawatan lashing muatan sesuai prosedur dan Deck rating kurang disiplin dalam pelaksanaan perawatan peralatan lashing muatan sehingga perawatan belum dilaksanakan secara maksimal. 2.Terlambatnya penyediaan peralatan lashing di atas kapal sehingga peralatan lashing di atas kapal kurang mencukupi dan rusaknya sebagian peralatan lashing di atas kapal menyebabkan peralatan lashing di atas kapal tidak mencukupi.

Baja dengan berbagai kegunaannya memiliki peranan penting dalam proses permesinan dan kontruksi. Dalam pengunaanya, baja dipilih karena kekuatan keuletan dan kekerasan yang dimilikinya salah satu jenis baja yang bisa dipakai pada proses permesinan adalah baja S50C namun dalam pengunaannya sebagai bahan pisau pengurai sabut kelapa. Tujuan dari penelitian adalah sebagai berikut yaitu mengetahui hasil kekerasan material dari hasil quenching dan hardening dengan variasi waktu penahanan (holding time) lalu mengetahui nilai kekerasan spesimen raw material dengan spesimen setelah hardening dan mengetahui pengaruh struktur mikro pada baja S50C dengan menggunakan air sebagai media pendingin dengan proses hardening. Metode penelitian yang penulis gunakan adalah experimental dimana baja S50C diberi pre-hardening pada temperatur 650°C dengan holding time 10 menit lalu di hardening pada temperatur 900°C melewati temperatur austenite 727°C dengan variasi holding time 60 menit, 90 menit dan 120 menit, kemudian didinginkan secara cepat dengan air sumur dengan waktu 3 menit. Hasil penelitian menunjukan bahwa nilai kekerasan tinggi terdapat pada variasi waktu 120 menit dengan nilai kekerasan sebesar 723,53 HV (meningkat 68,30 dari raw material) dan nilai kekerasan terendah pada variasi waktu 60 menit sebesar 560,71 HV. Dari pengujian struktur mikro pada baja S50C dengan pembesaran 500x menunjukan variasi waktu 120 menit memiliki struktur mikro martensite paling banyak.

Flipping the script: Assessing clinical judgement in student-led clinical evaluation
Authors: Kokan Michelle House , Jetha Farah
Published: September 2024

Introduction and background: Strong clinical judgement and reflective thinking and practice are imperative to make safe, ethical clinical decisions, particularly in today’s complex healthcare environment. Yet clinical judgement and underlying thinking are challenging to assess in post-licensure specialty nursing clinical education due to their complexity and invisibility.Methods: Problem: Clinical evaluation can be subjective, based on observed behaviours rather than on assessment of thinking processes and clinical judgement underlying students’ clinical decisions and actions. Approach: The BCIT Clinical Evaluation Tool (CET) and Evaluation Process (CET-EP) were developed using a shared accountability approach that shifts responsibility for demonstration of learning from instructor/preceptor to student, and facilitates the reflective thinking and practice necessary to develop clinical judgment.Conclusions: Use of this CET-EP in post-licensure specialty certificate programs has assisted instructors, preceptors, and students to reach insights into learners’ thinking, tailor learning interventions, and promote reflective practice, as well as provided greater objectivity in clinical evaluation.
