Ecological cybernetics of technological processes, both as a scientific and educational subject, along with the improvement of theoretica1l knowledge in the application of technological processes improved by nanotechnologies, where the design technologies are intensively updated with new hardware and software of design technologies, will allow providing professional approach to the project development, ecological expertise as an environmental engineer. It is known that the performance of technological processes optimally reduces its impact on the environment. However, this does not answer the question of how much. In my view, studying ecological cybernetics of technological processes will provide the evaluation of ecological level in technological processes performed under complex technological, constructive design conditions. In other words, each optimum oil processing and petrochemical processes must be investigated as a research object, and technological and constructive parameters of the equipment, efficiency of the catalysts in the process, the composition of the raw material, processing depth must be studied, improved and brought to more advanced stages. It is known that re-refining of oil and petrochemical processes are performed in the combination of more complex conversions and more complex structural design of equipment and one of the useful ways of improving ecological condition is to determine a new level by increasing cybernetic bases of the process.

This paper investigated the physical properties of particleboard produced using Biodegradeable wastes (Rice husk , Sawdust, Breadfruit seed coating, Oil palm fruit fiber) and plastics. Five samples were examined. The moisture content, ash content, thickness swelling percent, water absorption percent, density, surface appearance, of these produced samples, were all examined and compared with the control sample (medium dense fireboard, (MDF)). The mean density of the board ranges from 240kg/m³ to 648kg/m³. The moisture content ranges from 21.81% to 69.39%. water absorption percent and thickness swelling percent ranges from 19.24% to 119.94% and 5.88% to 38.46% respectively at two hours soaking, 70.99% to 219.6% and 5.88% to 66.67% respectively at 24 hours soaking. The control sample (purchased medium dense fireboard, (MDF)) recorded the highest density (643kg/m³), highest ash content (9.55%), lowest moisture content (16.08%), lowest thickness swelling and water absorption percent (19.24%,5.88%) at 2 hours soaking in water, lowest thickness swelling and water absorption percent (70.99%,5.88%) at 24 hours soaking in water . Sample A (particleboard produced with Rice husk) gave the best performance among other produced samples for physical properties. Generally, the results of the physical properties of the samples were comparable to the control sample (MDF) which is available in the local Market.

As part of the inventory of endogenous soil knowledge in Cote d'Ivoire, research was carried out on plinthitic soils (cuirassed soils) in Seguela, in the north-west of the country. The study combined surveys of farmers, laboratory analysis of the physico-chemical characteristics of the soils and statistical analysis of the data obtained. The results show that the vast majority of farmers own leathery land, but only some manage to cultivate it, often out of necessity due to dwindling arable land, while others give it up because of the difficulty of the work. Farmers recognise these armoured areas by the presence of hills and typical plant species. These plant species play an important role in the decision to cultivate these soils. Plants such as Isoberlinia doka (Caesalpiniaceae), Uapaca togoensis (Euphorbiaceae), Combretum micrantum and Manotes kerstingii (Dipterocarpaceae) are indicative of the fertility of cuirasse soils. On the other hand, the presence of Pericopsis laxiflora (fabaceae), Combretum molle (Combretaceae), Gardenia ternifolia (Rubiaceae) and Combretum lecardi on hardpan soils indicates the poverty of these soils. Compared with non cuirassed soils, cuirassed soils can be less acidic, with a higher capcity of exchangeable bases. These results attest to some local knowledge in terms of plant species indicative of soil fertility. However, the presence of slabs of armour would constitute obstacles to their agricultural development.

Top cross can be defined as the hybridization or a cross performed between an open pollinated variety (OPV) and either a single cross hybrid or an inbred line. This study assessed the performance of 21 yellow hybrid maize evaluated at Kishi and Ibadan during the 2020 and 2021 farming seasons. A Randomized Complete Block Design (RCBD) with three replications was used to set up the experiment on each site. The ANOVA result showed significant differences among the genotypes for all the traits except for plant and ear aspect. Hybrid TZEI 8 X DMR-LSR-Y (4.57 t ha^-1) had the highest yield. TZEI 8 X DMR-LSR-Y was the earliest to remove tassel (51 days) and hybrid TZEI 12 X ART98-SW1-Y was the earliest to exhibit silk (55 days). TZEI 12 X DMR-ESR-Y was noted for its significantly tall plants and ear placement. Positive non-significant correlation was observed between grain yield and plant height and also for grain yield and ear height. Ibadan 2020 had the best performance for grain yield (5.25 t ha^-1) followed by Kishi 2020 and Ibadan 2021 had the lowest yield per location. TZEI 12 and TZEI 8 were observed to be the best female parents while DMR-ESR-Y, PROVIT-A and BR9928-DMR-SR-Y are similarly observed as the best male parent in the hybrid combinations. This study can be repeated at the locations used and at other locations to confirm the yield and pattern of response of the maize hybrids across locations and years.

This study analyzes the perceptions of local communities regarding the dynamics of plant and animal species in the Tiogo Classified Forest (TCF). Based on field surveys and direct observations, the research reveals a significant decline in forest cover, perceived by 83.49% of respondents as advanced degradation. Paradoxically, some plant species are reported to be expanding particularly Guiera senegalensis, Lannea microcarpa, and Acacia macrostachya suggesting an adaptive response to environmental and anthropogenic pressures. From a faunal perspective, species perceived as increasing include the hare, partridge, and monkey, while large mammals such as the lion, buffalo, and elephant are widely reported as disappearing. The degradation of the TCF is attributed primarily to human activities, including bushfires, gold panning, agricultural clearing, uncontrolled fires, and demographic pressure. Natural factors are rarely mentioned. Furthermore, the perceived utility of species influences local assessments of their abundance, potentially biasing the evaluation of their actual status. These findings highlight the urgency of implementing conservation and sustainable management strategies that integrate local knowledge with scientific approaches to preserve biodiversity and enhance the ecological resilience of the TCF.

Objectives: To comprehend the etiopathogenesis, clinical presentation and abnormalities associated with this rare congenital defect along with diagnostic modalities and effective management techniques for the treatment of TTE in children by conducting a retrospective analysis using clinical information from 14 cases over a period of 10 years.

Methods: Children with TTE were enrolled in this study that underwent treatment between January 2014 to January 2024 at the Institute of Mother & Child Health (IM&CH) PUMHSW, Shaheed Benazirabad, Nawabshah, Pakistan. Clinical data including age, clinical manifestations, TTE-associated anomalies, ultrasonographic findings, and surgical procedures was collected from medical records of all patients. Follow up was conducted up to a period of 6 months.

Results: All 14 cases were treated successfully using laparoscopic surgery. Most of the cases presented with Inguinal Hernia along with TTE and the diagnosis was made intraoperatively except for four cases out of which one was diagnosed during clinical examination of abdominally palpable testes, while ultrasonography was conducted as a baseline modality for investigating TTE. Follow up of all the cases was achieved for not more than 6 months.

Conclusion: TTE must be suspected in patients presenting with nonpalpable undescended testis and contralateral inguinal hernia. The contralateral processus vaginalis sac is found in all instances of TTE. Ultrasonography is necessary for a prompt diagnosis of TTE. Laparoscopic surgery is a secure, efficient, and minimally invasive treatment modality for successful correction of TTE.

Compression garments are being used in applications such as socks, tights, and sleeves, and have been intended to apply pressure to muscles and tissues, so as to enhance circulation, decrease swelling, and potentially improve recovery after exercise. Despite their wide range of uses in sports, their effectiveness and benefits need to be explored further and research is on to explore their potential.

This study compares the land surface temperature (LST) of green roofs and cool roofs in Seoul to assess their effectiveness in mitigating urban heat islands and enhancing resilience to cold waves. Using Sentinel-2 imagery for rooftop classification and Landsat-8 thermal data for LST estimation, we analyzed 169 green roofs and 338 cool roofs, matched by area and location. Results show that green roofs consistently maintain lower LSTs during summer (mean 39.83°C, SD 3.52) compared to cool roofs (mean 40.88°C, SD 2.19), with a statistically significant difference (t = -22.04, p < 0.001, Cohen's d = -0.39). In winter, the difference is smaller but still significant (green roofs: mean 3.13°C, SD 1.63; cool roofs: mean 3.33°C, SD 1.40; t = -8.49, p < 0.001, Cohen's d = -0.14). These findings are consistent with previous studies showing that both green and cool roofs can reduce rooftop and ambient temperatures and provide important energy savings, though the degree of effectiveness varies by climate and building characteristics [1-5]. Green roofs are particularly effective in providing stable thermal performance and reducing summer heat in humid climates, while cool roofs can offer substantial cooling and energy benefits, especially in hot, dry regions [2-4, 6, 7].

This paper focuses on different standpoints regarding the thermal stability of a horizontal porous layer under the action of vertical vibration. Different time scales are distinguished (i.e. vibrational, viscous, conductive and buoyancy). For the case in which the vibrational time-scale is much smaller than other time scales and the amplitude of vibration is smaller than the height of the layer, the so-called time-averaged method is adopted. The linear stability analysis reveals that the response of the system in this case is harmonic and vibration has a stabilizing effect. Weakly non- linear stability analysis reveals that bifurcation is of the supercritical pitchfork type and an expression for the Nusselt number has been obtained. Although the time-averaged method has the advantage of simplifying the governing equations and providing closed form expression for the optimum choice of control parameters, it fails to describe sub-harmonic modes. In the follow up, it is shown that the stability analysis under arbitrary time-scale relations, called the direct method, leads to the study of a second order parametric oscillator (Mathieu equation). The harmonic and sub-harmonic responses are distinguished. We have put forward a set of conditions from which the stability results obtained by the direct method may be compared with those of the time-averaged method. The validity of the time- averaged method for thermos-vibrational problem has been proved for the first time in porous media. The criterion for the onset of convection has been obtained and this result has been generalized. The behavior of sub-harmonic solution is emphasized. It is shown that at very high frequency, the onset of convection corresponding to this mode does not depend on frequency and is independent of gravity. The response of the solution will be in sub-harmonic mode.

Green energy recovery technologies facilitate the transformation of green energy into electricity, thereby reducing reliance on fossil fuels and optimizing the energy efficiency of transportation facilities. This publication analyses the advanced principles of ambient energy recovery technologies in the transport sector, focusing mainly on road and rail networks. The use of thermal energy from heat losses generated by engines and braking devices, the incorporation of solar energy into vehicles and facilities, and innovative wind power solutions that exploit air movement in tunnels or around rail networks are highlighted. Hydraulic energy, magnetic energy and piezoelectric vibration recovery devices are also being explored for their ability to power sensors, vehicles and installations. Despite encouraging results, obstacles remain in the way of improved performance, cost-effectiveness and adaptation to practical circumstances. Intensified cooperation between researchers, industry and policy-makers is crucial to accelerate the uptake of these technologies, while fostering a more environmentally- friendly and resilient transport ecosystem.

Unchecked Growth, Land-Use Changes, and Flood Risks in the City of Lakes:
Hyderabad, once celebrated as 'the City of Lakes,' is grappling with the aftermath of rapid urbanization, leading to significant alterations in its land-use pattern. The impact of this transformation has not only altered the city's landscape but has also increased the risk of urban flooding, a phenomenon exacerbated by the surge in population and climate change.

Postoperative fever is a common clinical challenge, and its etiology varies with the timing of onset. While infectious causes dominate the differential diagnosis, non-infectious etiologies such as drug- induced fever must not be overlooked, especially when clinical findings are inconclusive.

We report the case of a 43-year-old male with a prior diagnosis of appendiceal adenocarcinoma, who underwent a completion right hemicolectomy following an open appendicectomy. The early postoperative period was uneventful until postoperative day (POD) 5, when the patient developed intermittent fever spikes. Extensive workup—including laboratory investigations, imaging, and clinical examination—failed to identify any infective focus. A temporal correlation was noted between the administration of intravenous cefuroxime and the onset of fever. Discontinuation of the antibiotic on POD-7 led to complete resolution of symptoms, confirming the diagnosis of cefuroxime-induced drug fever.

Drug-induced fever, particularly due to β-lactam antibiotics like cefuroxime, remains an underrecognized yet significant postoperative complication. Characterized by a lack of systemic toxicity and resolution upon drug cessation, it should be considered when infectious causes have been ruled out. Awareness of this phenomenon is crucial to avoid unnecessary investigations and prolonged antibiotic use.

Contemporary periodontology is grounded in a detailed understanding of the anatomy and physiology of the tissues that support and surround the teeth. The periodontium, composed of the gingiva, periodontal ligament, cementum, and alveolar bone, forms a dynamic functional unit designed to absorb and distribute occlusal forces, facilitate nutrient exchange, allow controlled tooth mobility, and preserve the integrity of the gingival environment.

Historically, periodontal diseases, particularly periodontitis, were viewed primarily as infectious conditions. However, recent advances in molecular biology and genetics have clarified their multifactorial etiology, where disease progression is influenced by the interplay between genetic predisposition, host immune-inflammatory responses, and environmental factors. Periodontitis is now widely recognized as a probabilistic genetic disorder, in which the mere presence of a susceptible genotype does not ensure disease manifestation—additional external and internal risk factors are required.

This review aims to provide a comprehensive overview of the anatomical structures comprising the tooth attachment apparatus, describe their physiological roles, and contextualize the current understanding of periodontal disease etiology, with emphasis on the biological interactions that drive its initiation and progression.

Achieving optimal control over plaque is crucial for the effectiveness of both nonsurgical and surgical periodontal therapy. Brushing alone is insufficient to achieve this; additional interdental cleaning tools are necessary. There are many different types of interdental aids, including water jets, oral irrigators, rubber tips, wooden toothpicks, interdental brushes, and dental floss. Each of these has unique benefits and drawbacks. The size of the interproximal space, along with the individual's acceptance, dexterity, and motivation, all influence the selection of the appropriate interproximal cleaning aid. Consequently, the dentist can offer guidance tailored to the specific characteristics of each patient.

Objectives: Immediately loaded implants have evolved due to the constant need to achieve more efficient and satisfactory prosthetic restorations for patients.

The main aim of this study was the radiographical assessment of peri-implant marginal bone loss when immediate load was applied to rehabilitate patients with partially edentulous (when the extraction of all remaining teeth was indicated) or edentulous mandible or maxilla, using full-arch fixed metal or peek prosthesis.

Methods: Prospective, single-blind clinical study with a control group (metal) used to be compared to the experimental material (peek). An initial descriptive analysis and a bivariate analysis were carried comprising all the statistical contrasts needed for the evaluation of the relationship to bone loss.

Results: In the radiographic study performed after 4 months in the maxilla and after 3 months in the mandible, a vertical bone loss of 0.07 mm and a horizontal bone loss of 0.02 mm were observed. It is noticeable that smokers and patients with parafunctions showed a greater bone loss, compared with those patients who did not have these habits. These results were also observed in cases with immediate post-extraction implants, where immediate loading with full-arch prosthesis was performed. On the other hand, the insertion torque and the materials used are factors that result in lower bone loss.

Conclusions: The material peek, as well as the insertion torque applied to the implants, are factors that protect against peri-implant bone loss, both the risk of suffering bone loss and the amount of bone loss.

India is suffering from the worst water crisis in its history with some 6000 million facing acute water shortage. This crisis will worsen as the demand is projected to be twice the available supply in 2030. The extent to which surface water and ground water is becoming polluted by anthropogenic activities including untreated sewage discharge, is adding to the complexities. Thus building understanding about the basic fundamentals of water, waterbodies as a bioreactor and role of microbial community are pertinent for the revival of lakes or riverine system. Prioritizing the nature based strategies this paper attempts to identify the characteristics, diversity and distribution of microbes in waterbodies to work on it, for an appropriate treatment mechanism to ensure its use as an alternative water resource. Metagenomics tool was first time used to study sewage dynamics in contaminated Varal devi lake and Kamvari river in Bhiwandi city, Thane dist. MS, as Varal devi lake supply 5 MLD potable water and may have adverse consequences. Findings of soil and water samples revealed potential environmental and health risk as the lake and river water showed presence of novel or less-characterized Leptospira and Turneriella species dominant in the system localized in Varal devi lake pumping and inlet discharge site. Hydrogenotrophic Methanogens were detected in soil samples, where as it was absent in water. A detailed microbiome taxonomic breakdown, abundance across samples, and insights into its ecological and health significance is comprehended with the recommendations to take appropriate measures of nature based strategies for ecological restoration of the lake and riverine ecosystem. Decentralized sewage treatment by septic tanks interception and constructed wetlands is suggested, simultaneously with Kamvari river rehabilitation from zero order stream onwards. Restoration of flood plains and buffer zones are also necessary by action on the encroachments, for self-regulation mechanism of the nature to prevail. This paper is an attempt to create awareness among the stakeholders about the waterbodies with river basin approach and strengthen scientific communication for good water governance. Engineering infrastructures like conventional STPs lack understanding and design of biological concepts and operationalization, this has led to the deterioration of almost all waterbodies. Hence it is imperative to work with integrated approach for future demand and water resources management by handholding between the community and government agencies. Disseminating the idea of decentralized community driven water conservation, river rejuvenation initiatives and to encourage use of advanced genomic technology to understand sewage degradation science for wastewater treatment, was the main goal of this research work.
