Design of cold storage as a storage space for animal vaccines at PT. XYZ

A refrigeration system is a system used to cool a room or an industrial product in the food, pharmaceutical, beverage, vegetable, fruit, and other industries to maintain product quality. One of its uses is as storage for various kinds of pharmaceutical needs, including vaccines for both animals and humans. The problem with cold storage is that existing vaccine storage has been in operation for a long time so it is necessary to study whether it is still able to maintain the vaccine storage temperature, namely -80C. The aim of designing cold storage is to maintain a stable vaccine storage temperature. Because vaccines consist of various kinds of microorganisms that are easy to activate. To maintain the quality of the vaccine, cold storage is needed. The research methodology for writing this thesis is to collect design data from one of the vaccine storage industry companies, and literature studies, then analysis of cooling load planning studies, vaccine storage capacity in cold storage measuring 10 x 10 x m 3 meters and determine the power of the cooling machine using a system. standard vapor compression cooler. The results of the analysis of the refrigeration system planning study showed that the indoor vaccine capacity was 30,600 bottles or 2056,701 lbs (822,680 kg), storage temperature -80C, cooling load 308,133 Btu/hr, or 90,283 W, this system uses R 134 A refrigeration. Using refrigerant, power compressor 23.32 kW, or 32 HP, COP 3.9.

Synthesis and Characterization of an Alkali-Activated Binder from Blast Furnace Slag and Marble Waste

This study reports an alkali-activated binder including blast furnace slag (BFS) together with marble waste (MW). Cement is an industrial product that emits a significant amount of CO2 during its production and incurs high energy costs. MW is generated during the extraction, cutting, and processing of marble in production facilities, where dust mixes with water to form a settling sludge. This sludge is an environmentally harmful waste that must be disposed of in accordance with legal regulations. In this study, a substantial amount of MW, a by-product with considerable environmental and economic impacts worldwide, was utilized in the production of a binder through the alkaline activation of BFS. In doing this, different experimental parameters were tested to obtain the best binder samples according to workability and mechanical properties. Then, some experiments such as drying shrinkage determination, strength testing, and microstructure analyses were fulfilled through samples with the best values. The findings supported the improvement of the rapid-setting property of BFS by means of the addition of MW. MW reduced the time-dependent drying shrinkage values of BFS by 55%, especially in slag alkaline activation systems with a low or moderate alkali activator content. The substitution of MW (≤50%) in BFS increased flexural and compressive strengths (4.5 and 61.7 MPa), while a reference sample contained BFS only. Although the use of MW did not create a new phase, it contributed to a C-S-H bonding structure during the alkali activation of BFS in a microstructure analysis.

BackgroundGhee, known as “roghane heiwâni,” or “Kermanshahi oil” is a traditional fermented butter-like product highly esteemed for its nutritional value. Ghee is prepared using traditional methods and has substantial potential as a reservoir of probiotic microorganisms. Previous research delved into isolating and identifying lactic acid bacteria (LAB) in Kermanshahi through culture and PCR sequencing. This study seeks to elucidate the microbial profiles and diversity within Kermanshahi using culture, Denaturing Gradient Gel Electrophoresis (DGGE), and sequencing methodologies.MethodsTwenty samples of Kermanshahi oil were meticulously gathered from diverse locales across Kermanshah province. These samples were cultivated under specialized conditions in MRS and M17 environments spanning 24 to 72 h. Following DNA extraction, amplification of the 16SrRNA gene sequences was performed, culminating in sequencing for conclusive identification of the isolates. Furthermore, the DGGE technique was directly employed to separate and identify various species present in the oil samples utilizing bioinformatics software.ResultsSequencing outcomes revealed a diverse array of microorganisms among the isolates, with Lactobacillus constituting 43%, Streptococcus comprising 27.6%, Enterococcus at 4.61%, and yeasts at 7.6%. Other species exhibited lower frequencies, encompassing Rhizobium, Bacillus coagulans, and Staphylococcus hominis.ConclusionsThe isolation of a diverse spectrum of probiotic microorganisms underscores their potential utility in the realm of industrial dairy product production. These findings allude to the possibility of integrating these valuable microorganisms, which have historically been associated with traditional products, into the contemporary dairy industry. As consumer interest in probiotic-enriched products surges, the insights gained from this study pave the way for harnessing the benefits of Kermanshahi-derived probiotics.

Exposure to food additive mixtures and type 2 diabetes risk in the NutriNet-Santé cohort

Abstract Background So far, the safety evaluation of food additives has been performed substance by substance, while in real life, millions of individuals are exposed to mixtures of food additives daily. According to preliminary experimental data, some of these chemicals, alone and/or in synergy are suspected to impact metabolic health. The objective of this study was to investigate for the first time the associations between exposure to mixtures of food additives and type 2 diabetes (T2D) risk in a large prospective cohort of French adults. Methods Participants (n = 108,783, 79.2% women, mean age=42.4 years, SD = 14.6) from the NutriNet-Santé cohort (2009-2024) completed repeated 24h-dietary records, detailing industrial product brands. Additive exposure was assessed using composition databases and laboratory assays. Five mixtures of additives were identified through non-negative matrix factorisation (NMF). Associations between these mixtures and the risk of T2D were characterised using multivariable proportional hazards Cox models adjusted for known risk factors.

Abstract Background Experimental studies suggested potential detrimental effects of some food additive preservatives and antioxidants (PA) on metabolic health, but epidemiological data is lacking. This study aimed to investigate for the first time the associations between exposures to a wide range of PA and type 2 diabetes (T2D) risk in a large population-based cohort. Methods Participants (n = 108,723, 79.2% women, mean age=42.5y, SD = 14.6) from the French NutriNet-Santé prospective cohort (2009-2023) completed repeated 24h-dietary records including specific brands of industrial products. PA exposure was assessed using composition databases and laboratory assays. We characterised associations between time-dependent exposures to PA and risk of T2D using multivariable Cox models adjusted for known confounders. Results 1131 T2D cases were identified during follow-up. Exposures to the following PA were associated with a higher risk of T2D: potassium sorbate E202 (HR per a 25 mg/d increment=1.12, 1.08-1.17, p < 0.001), sodium nitrite E250 (HR 0.25 mg/d = 1.06, 1.00-1.12, p = 0.04), calcium propionate E282 (HR 25 mg/d =1.07, 1.02-1.12, p = 0.008), lecithins E322 (HR 100 mg/d =1.02, 1.01-1.04, p = 0.008), citric acid E330 (HR 500 mg/d=1.08, 1.04-1.12, p < 0.001), and phosphoric acid E338 (HR 50 mg/d=1.11, 1.05-1.18, p < 0.001). Conclusions This large prospective cohort revealed positive associations between T2D risk and exposures to several PA widely used in industrial foods. Key messages • This large prospective cohort revealed positive associations between T2D risk and exposures to several PA widely used in industrial foods. • If these results are confirmed, regulations governing PA’s use by the food industry could be re-evaluated for better short- and long-term consumer protection.

Nanoporous Structure Fabrication on Glass Surfaces for Enhanced Glass Adhesion Using Hydrogen Fluoride Gas.

The bonding between glass and other materials plays a crucial role when glass is used in industrial products. In this study, we propose a new approach to enhance the bonding strength of glass with other materials by fabricating nanoscale porous structures on glass surfaces via a chemical reaction with hydrogen fluoride gas. Herein, we present a methodology for controlling the thickness of the porous structure, clarify the relationship between the thickness and adhesion strength, investigate the shape of the formed porous structure, and propose a method to control its shape. Our findings reveal that the fabricated porous structure greatly improves the adhesion strength of the adhesive owing to the microscopic anchoring effect induced by the penetration of the adhesive into the porous structure. This approach is expected to be applied to architectural and automobile window glasses, solar panels, sensor cover glasses of autonomous vehicles, display devices (including smartphones), and wearable devices.

Selection of Conditions for the Synthesis of Methacrylate Monomers Based on Adamantane

AbstractAdamantane-based methacrylates are important monomers for the design of polymers used for the development of chemically amplified photoresists. Herein, we present the selection of reaction conditions for obtaining of 2-ethyladamantan-2-yl methacrylate, 2-methyladamantan-2-yl methacrylate, adamantan-1-yl methacrylate, and 3-hydroxyadamantan-1-yl methacrylate from adamantane derivatives and methacryloyl chloride. It is shown that the combination of pyridine as a solvent and base with 1,4-diazabicyclo[2.2.2]octane (DABCO) as a base allows reproducible preparation of the desired products with good yields. The results obtained provide valuable information for upscaling the synthesis of important products for the microelectronics industry.

Low-salt diets and salt-free cooking help reduce exposure to Per- and polyfluoroalkyl substances (PFAS)

BackgroundThe ubiquity of Per- and polyfluoroalkyl substances (PFAS) in various consumer and industrial products poses a significant public health challenge, but effective strategies to reduce human exposure to PFAS are limited. ObjectivesThis study aims to evaluate the association between dietary patterns, specifically low-salt diets and salt-free cooking, and serum PFAS levels in the general population. MethodsThe study analyzed data from 11,137 participants from the National Health and Nutrition Examination Survey (NHANES) using weighted linear regression. We assessed associations between low-salt or low-sodium dietary patterns and the way salt was used during cooking or food preparation and serum levels of five highly detectable PFAS compounds: perfluorooctanoic acid (PFOA), perfluorooctanesulfonic acid (PFOS), perfluorohexanesulfonic acid (PFHxS), perfluorodecanoic acid (PFDA), and perfluorononanoic acid (PFNA). Since consuming fish and shellfish is a major source of PFAS exposure in humans, the intake status of these foods was adjusted for in the sensitivity analysis. Additionally, other sensitivity analyses, including propensity score matching, were conducted. ResultsThe analyses showed a significant negative association between low-salt or low-sodium diet and serum levels of the five PFAS compounds. In contrast, regular use of salt in cooking or food preparation was significantly and positively associated with higher serum levels of PFAS. These findings were consistent across all models. Also consistent were the results of sensitivity analyses based on participants' consumption of fish and shellfish and propensity score matching. ConclusionsLow-salt or low-sodium dietary patterns, and salt-free cooking may be are associated with a reduced risk of PFAS exposure in the general population. While this study offers new insights into mitigating PFAS exposure, further validation in additional datasets is necessary, along with confirmation through intervention studies designed based on this hypothesis.

The Effects of Ubiquinone on the Antioxidant System in Male Rats Exposed to Saccharin-Induced the Hepatic Toxicity

Saccharin (Sac) is a widely used artificial sweetener with significant applications in the food industry, pharmaceutical formulations, and tobacco products. Despite its popularity, saccharin has drawn attention due to its potential carcinogenic effects and associations with various health risks, including renal impairment, hepatic dysfunction, obesity, and diabetes. This study aimed to investigate the protective effects of Ubiquinone, or coenzyme Q10 (COQ10), on liver toxicity induced by saccharin, focusing on oxidative stress and antioxidant markers. In this experiment, rats were divided into six groups of ten. The control group received no treatment, while the second group was administered COQ10 at a dosage of 20 mg per kilogram of body weight. The third and fourth groups were given saccharin at 1/10 and 1/20 of the lethal dose 50 (LD50), respectively. The fifth and sixth groups received saccharin at the same dosages as the third and fourth groups, but with additional COQ10 supplementation. All treatments were administered orally for 30 days, after which liver tissues were collected to assess oxidative stress and antioxidant markers. The results revealed that saccharin significantly increased oxidative stress in the liver, as evidenced by elevated levels of malondialdehyde (MDA) and oxidized glutathione (GSSG). Additionally, saccharin-treated groups exhibited a marked decrease in antioxidant markers, including reduced glutathione (GSH) and superoxide dismutase (SOD). However, the groups that received COQ10 alongside saccharin showed significant improvement, with oxidative stress and antioxidant levels nearly returning to those observed in the control group. These findings suggest that saccharin consumption promotes the generation of reactive oxygen species and contributes to liver damage, characterized by necrotic hepatocytes, sinusoidal dilatation, and inflammatory infiltration. The protective effects of COQ10 in mitigating saccharin-induced oxidative stress highlight its potential as a therapeutic agent for preventing liver damage associated with saccharin intake.

Cu/N-doped carbon spheres derived from soybean flour as an active green nanocomposite for the synthesis of 1,4-disubstituted 1H-1,2,3-triazole derivatives

Cu immobilized onto N-doped carbon spheres (Cu/N-doped CS) derived from soybean flour was synthesized via the hydrothermal method and certified as a green high-efficiency catalyst for the regioselective synthesis of 1,4-disubstituted 1H-1,2,3-triazoles. The obtained N-doped carbon spheres from a combination of glucose and soy flour have a larger size and suitable affinity for load copper species. The morphology and structure of the as-prepared catalyst have been confirmed based on FT-IR, XRD, FE-SEM, EDX, BET, and ICP-OES characterizations. The catalytic performance of the Cu/N-doped carbon spheroids was investigated experimentally. It was found that the Cu/N-doped CS nanocomposite has a high efficiency and recyclability for 5 cycles without any appreciable loss in its catalytic activity in the synthesis of 1,4-disubstituted 1H-1,2,3-triazoles via the three-component condensation reaction of various epoxide/alkyl or aryl halides, sodium azide, and phenylacetylene in a water medium. Furthermore, significant advantages such as stability, ease of preparation, low cost of the carbon resource, high regioselectivity, and good product yield have been achieved in the heterogeneous catalyst system attractive for large-scale in many industrial products.

Processes of Metal Oxides Catalyst on Conversion of Spent Coffee Grounds into Rich-Synthesis Gas by Gasification

Spent coffee grounds (SCGs), a waste product of the coffee industry, present a significant untapped resource for fuel production. This study aims to optimize the gasification of SCG using various metal catalysts (NiO, MnO2, Al2O3, and Fe2O3) to maximize syngas yield. SCG samples were gasified at different temperatures (800 °C, 900 °C, 1000 °C) and analyzed using Scanning Electron Microscopy (SEM), Thermogravimetric Analysis (TG-DTA), and Fourier Transform Infrared (FTIR) spectroscopy to evaluate catalyst performance and reaction mechanisms. The findings indicated that utilizing mixing techniques for physical contact to introduce catalysts led to a uniform distribution of catalyst particles throughout the sample. The decomposition rate of the gasification experiment after adding the catalyst was 24% faster than that of the pure SCGs. In the gasification experiment, the MnO2 catalyst showed the highest CO production, which was 71% higher than that of NiO under the same conditions. At this temperature, MnO2 generated around 171% more CO than at 800 °C, surpassing the yields observed with other catalysts. The study concludes that Mn emerged as the most promising catalyst, significantly improving both CO and CH4 yields. Selecting the appropriate metal catalyst and optimizing operational temperatures are crucial for enhancing the efficiency of SCG gasification.

Echoes of Speculation Underway in Relations Between the Occident and China

In a previous article I talked about speculative waves in sequence that have hit the global economy since the 2000s in a world struggling with deflation. Well, this wave of speculation has not stopped but today it seems to concern the transfer of industrial plants from the West to China. A process that was born with the good intentions of transferring industrial activities to developing countries with the dual objective. Give a boost to the economy in developing areas and at the same time reduce the management costs of large multinationals' plants. A process therefore that was born with a positive sign in the intent to help a coordinated development of the territories and a reduction in the costs of industrial products. Meanwhile, the objective of coordinating the development of the territories and continents has not been achieved and on the contrary the process has led to an almost exclusive delocalization of industrial production from the West to China. The excess of industrial localization has exacerbated the concentration of unassimilable waste with a worsening of the disease of the planet struggling with atmospheric overheating. The process, therefore, has been slowed down but not stopped for natural reasons. On the other hand, the acceleration of the development of the Chinese economy has also marked a halt coinciding with the spread of the global epidemic. After about fifty years of accelerated economic growth, the Chinese community has sensed the change in the country's economic prospects and has pulled the brakes on both consumption and investments, marking the end of the accelerated race on the road to development. The picture of the speculative evolution of industrial delocalization processes sees together the interest of mega companies in reducing management costs which is congenial to the increase in the financial values of companies that increase on the Western stock exchanges. In other words, delocalization helps reduce management costs and at the same time seems to support ultra increasing financial values. In short, it plays into the hands of speculation which is certainly not the interest of global social and economic development which instead requires coordination of the territories on the road to development. With the further dilemma that the fate of the global economy may be in the hands of the Boards of Directors of mega companies and not of states and communities.​

Cross-Linked Polyolefins: Opportunities for Fostering Circularity Throughout the Materials Lifecycle.

Cross-linked polyolefins (XLPOs) constitute a significant portion of the plastics commercial market, with a market size of a similar order of magnitude to those of polystyrene and polyethylene terephthalate. However, few aspects of XLPO materials circularity have been examined relative to thermoplastic polyolefins. The cross-linking of polyolefins imparts superior performance properties, such as impact strength, chemical and electrical resistance, and thermal stability vs thermoplastic analogues, but it also makes the reprocessing of XLPOs to valuable products more challenging, as XLPOs cannot be molten. Thus, most XLPOs are incinerated or landfilled at the end of the first lifecycle, even though XLPO products are commonly collected as a relatively clean waste stream-providing a unique opportunity for valorization. In this review, we discuss approaches to improve XLPO circularity throughout the entire materials lifecycle by examining biobased feedstocks as alternative olefinic monomer sources and by assessing both traditional mechanical and advanced XLPO recycling methods based on industrial feasibility and potential product value. We also consider how advancing materials longevity can reduce environmental impacts and lifecycle costs and how recyclable-by-design strategies can enable better end-of-life opportunities for future generations of XLPO materials. Throughout this review, we highlight XLPO circularity routes that have the potential to balance the performance, circularity, and scalability necessary to impart economic and environmental viability at an industrial scale.

Stimulating Acidimicrobium sp. Strain A6 in iron-rich, acidic sediments from AFFF-impacted sites for PFAS defluorination

Per- and polyfluoroalkyl substances (PFAS) are persistent and bioaccumulative contaminants that are widely used in industrial applications and consumer products and pose significant risks to ecosystems and human health. Acidimicrobium sp. Strain A6 (A6), which is common in acidic, and iron rich soils and sediments is capable of both anaerobic ammonium (NH4+) oxidation under iron reduction (Feammox) and defluorination of perfluorinated alkyl substances, such as perfluoroalkyl acids (PFAAs). This study investigates the potential for biostimulating A6 via the supply of NH4+ and ferric iron (Fe(III)) with the goal of defluorinating PFAAs. Sediment samples from acidic, iron-rich, AFFF (aqueous film forming foam) impacted sites were collected and incubated with added Fe(III) and NH4+. Quantitative PCR was used to track A6 numbers as well as dehalogenase and F− ion transporter genes during these incubations; changes in the microbial community structure were tracked through 16S rRNA gene sequencing. The findings reveal that the addition of Fe(III) and NH4+ stimulated the Feammox reaction and A6 growth and enhanced the degradation of perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS). Results also show a significant presence and activity of the above-mentioned genes in these incubations. The insights gained from this study could inform bioremediation strategies for PFAS-contaminated environments, especially in geochemical settings that favor the presence of A6.

Characterization, generative design, and fabrication of a carbon fiber-reinforced industrial robot gripper via additive manufacturing

Robot grippers are crucial components across various industrial applications, requiring special design and production for obtaining the optimal performance. Conventional plastic injection moulding techniques fall short in achieving the specificity needed for these grippers. To address this challenge, current paper focuses on developing a robot gripper using carbon fiber-reinforced polyamide with a next-generation composite filament and employing the innovative Generative Design technique. In the work, we began by characterizing and optimizing the composite material specifications. Then, the tensile strength and fracture mechanics of standard samples based on printing parameters, applying Taguchi experimental design for optimization were evaluated. Analysis of Variance (ANOVA) was used for factor analysis to fine-tune the process. Using the Generative Design technique, we determined optimal geometries, which were then fabricated through Fused Deposition Modeling (FDM). As a result, the optimization efforts led to significant improvements i.e., tensile strength increased from 103.2 to 116 MPa, and the elasticity modulus from 8386 to 8990 MPa. In practical industrial applications, we achieved a reduction in material weight from 14 to 4 g, lowered production costs from $5.16 to $1.50, and cut production time from 58 to 28 min. This study presents a validated method for developing industrial products with reduced material usage and costs, promoting sustainable production practices.
