Description:

Since the 1970s oil crisis, Pinch Analysis (PA) has been employed as a heat recovery guidance tool to address the need for energy conservation. With the continuous improvement of the theoretical system and the ongoing innovation of the methodology, PA has not only been deepened and developed within the energy domain but has also been extended to other important problem domains, enabling optimal resource utilisation and becoming an indispensable analytical methodology for the integration of process industries. This review builds upon a critical review published in 2018 and summarises the recent advancements (2018 to the present) of PA in the domains of process modelling and energy optimisation, energy system process integration, resource network optimisation, freshwater integration, carbon emissions integration, plastics management networks, and energy-water-carbon nexus. It also summarises the tools used by PA methods and looks at the future development of PA in various fields. The main findings of this review are: 1) PA has evolved in recent years towards multi-methodology, multi-dimensionality and multi-objectives, as well as a greater focus on dynamic adaptability when dealing with complex application scenarios; and 2) according to the reported data of works reviewed in this paper, a diversified and effective tool chain and specialised tool (e.g. Aspen, Water Pinch, CEPA) can achieve up to 75% savings in energy consumption and resources in specific industrial cases.

Measuring and control the hysteresis loop by using analog and digital integrators

Miklós Kuczmann Zoltán Pólik

Publication Name: Journal of Optoelectronics and Advanced Materials

Publication Date: 2008-01-01

Volume: 10

Issue: 7

Page Range: 1861-1865

Description:

We have managed to build up a computer controlled measurement system applying National Instruments Data Acquisiton card and National lnsturments LabVIEW software package. First, in a previous study, the specimen under test has been simulated by the Jiles-Atherton model of hysteresis, but simulated measurements have been performed using LabVIEW functions. Our main goal now is to control the magnetic flux density measured by using a toroidal shape core with a feedback controller. In this paper, we show the developed procedure which is able to measure the hysteresis characteristics applying analog and digital integrators, and to control the waveform of magnetic flux density determined from the induced voltage of the secondary coil wound on the toroidal shape core. Our experience is that the developed controller is robust. This work is an initial step of the vector hysteresis measurement system.

Shelf life of bottled water – field conditions in Hungary

Rajmund Kuti Judit Molnár Bendegúz Papp Rita Molnár Dóra Beke

Publication Name: Journal of Food and Nutrition Research

Publication Date: 2020-01-01

Volume: 59

Issue: 4

Page Range: 361-366

Description:

Professional soldiers and firefighters are deployed to deal with the consequences of various disasters, where their supply is carried out under field conditions. This study investigated whether improperly stored bottled drinking water can change its quality and pose a biological hazard. Microbiological quality of 20 samples of bottled mineral water produced in Hungary, including 10 uncarbonated, 5 carbonated and 5 flavoured mineral water samples, was investigated under field conditions. Culturable microorganisms were enumerated by ISO 6222:1999; coliforms and Escherichia coli by ISO 9308-1:2000; Pseudomonas aeruginosa by ISO 16266:2006; Enterococcus spp. by ISO 7899-2:2000; and Clostridium perfringens by ISO 14189:2013. In six cases among uncarbonated water samples, the aerobic colony counts exceeded the standard value. Furthermore, coliforms and P. aeruginosa were detected in three cases. However, in carbonated and flavoured mineral water, no samples of unacceptable bacteriological quality were observed, as their pH value was significantly lower and that probably did not favour proliferation of bacteria. Due to their acidic condition, carbonated and flavoured mineral water appears to be less vulnerable to microbiological contamination under field conditions. During flood damage remediation, it is advisable to perform the supply of intervention units with carbonated and flavoured mineral water to avoid infection.

The Potential for Analyzing the Correlation Between the Compressive Stress Resistance of Red Clover Seeds and the Environmental Conditions during Seed Maturation Using FT-IR Spectroscopy

Eszter Kókai Gergely Zoltán Macher Dalma Bódizs Anett Bedő M. Lócsi Szilveszter Gergely

Publication Name: Chemical Engineering Transactions

Publication Date: 2024-01-01

Volume: 114

Issue: Unknown

Page Range: 715-720

Description:

The paper aims to examine the connection between environmental conditions during seed maturation and the ability of seeds to compressive stress, supported by statistically significant findings. The study involves using Fourier transform infrared (FT-IR) spectroscopic analysis on red clover seeds under varying pressure levels, specific tensions, and selected quality parameters. The methodology relies on a general FT-IR spectroscopic approach, with spectral comparisons made against results from pressure-induced rupture. Through this research, new methods for seed testing are intended to be informed by differential and correlation results across technical parameters and different measurement settings. The analyses indicated a noticeable difference of several 10 N in visible features between seed maturation stages and compressive tolerance. Given the novelty of the aspects being explored, one primary influencing factor is identified as the scarcity of available literature, which also serves as a limitation of this research. The obtained results have potential applications for analysts, agricultural specialists, consultants, and experts involved in seed management and distribution.

Direct Terpene extraction from aromatic herbs: Comparative evaluation of ultrasound-assisted stir bar sorptive extraction and ultrasound-assisted extraction by HPLC-PDA with AGREE/AGREEprep greenness assessment

Áron Béni Tarek Alshaal Arjun Muthu Gréta Törős Safa Labidi Attila Kiss Reina Atieh Tammem Hamda

Publication Name: Journal of Food Composition and Analysis

Publication Date: 2026-07-01

Volume: 155

Issue: Unknown

Page Range: Unknown

Description:

This study presents the development and comparison of two extraction methods: ultrasound- assisted stir bar sorptive extraction with liquid desorption (UA-SBSE-LD) and ultrasound-assisted extraction (UAE) for the isolation and quantification of six major terpenes and terpenoids (thymol, carvacrol, eugenol, p-cymene, γ-terpinene, and α-pinene) from culinary aromatic herbs. The analytes were analyzed by high-performance liquid chromatography with photodiode array detection (HPLC-PDA). For UA-SBSE-LD, the effects of key extraction parameters, including adsorption time, ionic strength, pH, desorption solvent composition, desorption time, and solid:liquid ratio, were investigated, while UAE was evaluated using a water–ethanol system without pH adjustment. Both techniques demonstrated excellent linearity (R² ≥ 0.9805), acceptable detection limits (0.21–17 µg/mL), and satisfactory recoveries (82–120%), meeting validation requirements. Applied to thyme, oregano, rosemary, and basil, UA-SBSE-LD outperformed UAE for volatile hydrophobic compounds like γ-terpinene and α-pinene, yielding higher extraction efficiencies without organic solvent pretreatment. UA-SBSE-LD achieved up to 6.89 mg/g of α-pinene from rosemary and 4.04 mg/g of eugenol from basil. The sustainability of the methods was evaluated using AGREE and AGREEprep tools, indicating a greener profile for UAE. The direct application of UA-SBSE-LD to solid plant matrices, coupled with HPLC-PDA, represents a sensitive alternative to gas chromatography-based methods for determining terpenes in food matrices.

Study of the antifungal effect of a copper-containing foliar fertilizer

Balázs Ásványi Renato Kalocsai E. Lakatos Viktoria Vona Tamás Szakál Zsolt Giczi

Publication Name: Cereal Research Communications

Publication Date: 2021-06-01

Volume: 49

Issue: 2

Page Range: 337-341

Description:

Winter wheat (Triticum aestivum L.) is one of the most important arable crops. Copper-containing fertilizers are used in crop production to treat or reduce the negative effects of copper deficiency. Various copper compounds are also widely used as effective fungicide agents. The influence of a copper-containing foliar fertilizer prepared from a copper solution and sucrose had been tested on the yield and raw protein content of winter wheat in previous field experiments. In this work, we studied the antifungal effect of this particular foliar fertilizer in an in vitro trial, wherein the fungicide effect on growth and reproduction of specific plant pathogens, i.e., Fusarium graminearum and Drechslera sorokiniana, was evaluated with the agar well diffusion method. The results showed that doses of the foliar fertilizer corresponding to field applications of at least 1 kg ha−1 had antifungal effects, which were significant (P < 0.01) above the concentration level of 3337 mg L−1, corresponding to 2 kg ha−1 application, against both fungal pathogens. A linear correlation (r2 > 0.95) was found between copper concentration and fungicide efficiency in the concentration range studied. The fungicide efficiency of the foliar fertilizer was lower than that of the commercially available copper-oxychloride fungicide. The sole use of the foliar nutrient tested probably cannot replace fungicide treatments. However, in addition to its plant nutrition effect, its antifungal properties should also be taken into consideration.

Computational thinking and self-leadership as predictor of innovative work behavior among employees in green product firms : An explanatory sequential mixed method

Hamid Waqas Md Billal Hossain Saad Saif Bin Li

Publication Name: Acta Psychologica

Publication Date: 2026-07-01

Volume: 267

Issue: Unknown

Page Range: Unknown

Description:

This study employed an explanatory sequential mixed-method design to investigate the factors influencing innovative work behavior in green product firms in Pakistan. Guided by social cognitive theory, data from 278 employees were analyzed using structural equation modeling in AMOS, followed by qualitative interviews to further explain and contextualize the quantitative findings. The findings showed that computational thinking (β = 0.62, p < 0.001) and self‑leadership (β = 0.56, p < 0.001) have a significant positive association with creative self-efficacy. Additionally, creative self-efficacy has a significant direct positive influence on innovative work behavior (β = 0.76, p < 0.001). The mediation analysis confirmed that creative self-efficacy significantly mediated the relationship between computational thinking and innovative work behavior (indirect β = 0.29) and between self‑leadership and innovative work behavior (indirect β = 0.26). Notably, knowledge sharing significantly moderated the relationship between creative self-efficacy and innovative work behavior (β = 0.32, p < 0.001) strengthening the effect of creative self-belief on innovative. Eighteen (n = 18) interviews were conducted to gain insight into how these mechanisms worked. During the thematic analysis, results revealed that knowledge sharing weakens negative effect of hierarchical constraints, enabling employees to act on their creative self-efficacy. Computational thinking is associated with a language of credibility for innovative ideas, while self‑leadership is associated with a necessary internal motivation against bureaucratic fatigue. These findings are relevant for green product firms operating in high power distance, resource-constrained contexts such as Pakistan.

Understanding the psychology of knowledge sharing and experience in digital service ecosystems

Ankit Mehrotra Attila Kurucz Rsha Alghafes Nidhi Sahore Jaskirat Singh Rai

Publication Name: Acta Psychologica

Publication Date: 2026-07-01

Volume: 267

Issue: Unknown

Page Range: Unknown

Description:

Drawing on service-dominant (SD) logic, which conceptualizes value as emerging through resource integration and use rather than direct technological outputs, the study examines how technology-mediated knowledge-sharing platforms (TMKSP) influence employee and employee-perceived customer experience using the DART (dialogue, access, risk assessment, transparency) framework of value co-creation. Employing a mixed-method approach, a pre-hoc qualitative study (Study A) identified key TMKSP features relevant to value co-creation, which informed the development of a DART-based survey for the quantitative phase (Study B). Data from retail employees were analyzed using PLS-SEM with two-tailed bias-correct bootstrapping. The findings show that TMKSP significantly improves employee experience via platform access and reduced perceived risk, while enhancing employee-perceived customer experience through employee-customer dialogue and platform transparency. Mediation analysis confirms the explanatory role of DART-based constructs in linking TMKSP with experience outcomes, although the mediating role of perceived platform risk was not supported. The study contributes theoretically by operationalizing SD logic within an internal service ecosystem and demonstrating how value-in-use is shared through employee-perceived co-creation conditions rather than through direct technological effects. It offers practical guidance for managers aiming to design employee and customer-centric knowledge-sharing ecosystems.
