Evaluation of short and ultra-short dental implants in challenging clinical situations of resorbed ridges: A narrative review
Authors: Goswami Roma , Trivedi Anshul , Kumar Ayush
Published: April 2024

Background:

Dental implant treatment has gained widespread acceptance as a reliable method for replacing lost teeth. Nevertheless, the favorable outcome of implant therapy hinges on having adequate bone quality and quantity. Individuals with restricted bone height or density pose a unique challenge for implant placement. Short and ultra-short dental implants offer an alternative solution for such patients, as they necessitate less vertical bone height and can mitigate the necessity for supplementary bone augmentation procedures.

Aim:

This narrative review was conducted to understand the different types of short and ultra-short implants, their indications and contraindications, and their prosthetic considerations, summarizing the current literature on the clinical outcomes, success rates, and potential complications.

Methods:

Research publications were searched on search engines such as EBSCO, EMBASE, PubMed, Web of Science, and Cochrane library databases, and the articles published from January 1988 to December 2022 with terms such as “short implants, ultra-short implants, atrophic ridge, and alveolar ridge augmentation” were collected.

Results:

A total of 10 articles were collected, and they were further used to formulate this review. Despite their constraints, short and ultra-short implants have demonstrated comparable clinical results to conventional implants in specific scenarios and provide several advantages, such as reduced surgical time, lower costs, and decreased risk of anatomical complications.

Discussion:

Short and ultra-short dental implants are used when regular ones are not feasible. They increase stability by enhancing bone contact. They work well for various dental prostheses, especially for those who cannot use removable options. While not recommended for everyone, they can be successful in many cases. Factors such as implant shape, surgical technique, and prosthetic considerations play a key role in their success. Studies show high survival rates for short implants, making them a reliable choice for specific situations. They offer a less invasive and cost-effective alternative in challenging cases.

Conclusion:

As technology and designs continue to advance, the adoption of short and ultra-short implants is expected to see a rise in implant dentistry. It is imperative to exercise careful patient selection, comprehensive treatment planning, and precise execution of both surgical and prosthetic techniques for the successful implementation of implant therapy with short and ultra-short implants.

Authors: Abbas Rezhat , Shah Zeenat , Dar Mohammad Shafi , Latoo Suhail Hamid
Published: April 2024

Background:

Teeth are an excellent source for genetic and forensic studies. Teeth exhibit minimum morphological change and are easy to inspect. Because of their resistance to fire and bacterial breakdown, they are useful for forensic identification. Tooth dimension can be employed to determine age and gender. “Sexual dimorphism” means distinctions in height, stature, and appearance between men and women that can be used in dental identification.

Aim:

With this background, a study was conducted to figure out canine tooth dimorphism as an aid in sex determination among the Kashmiri population.

Materials and Methods:

A hospital-based retrospective study was undertaken on the Kashmiri people. The casts were picked from the Government Dental College and Hospital Srinagar’s Postgraduate Department of Orthodontics. A total of 100 casts were chosen (50 each from men and women). The mesiodistal diameter of maxillary and mandibular canines was measured with a digital vernier caliper. The measurements were entered into an Excel spreadsheet and statistical analysis was performed to determine gender differences.

Results:

Males and females have considerably varied maxillary and mandibular canine mesiodistal proportions. However, data regarding sexual dimorphism in mandibular right canines were fairly stable.

Conclusion:

According to the findings of this study, males had greater mean mesiodistal dimensions than females.

It proposes a viable idea for tackling the practical wireless multimedia massive data transmission model problem by applying the method to the real-time processing process in other sectors with high importance and resilience.
Research on the Technical and Economic Development of Large Megawatt Wind Turbines Based on Medium-Voltage Electrical System
Authors: Liu Wei , Wang Rui , Chen Chen
Published: April 2024

INTRODUCTION: With the advent of the "bidding era" and "parity era" in the wind power market, the competition of the whole machine factory is becoming more and more fierce, and the capacity of the single fan is getting larger and larger, which becomes the key to the design of the fan electrical system of the large-capacity unit (5.XMW or more). At present, the low-voltage wind power system (690V,1140V) is the common solution for wind turbines. However, due to the limitation of the cable section of low-voltage electrical system and the increase of the rated current of the generator, the increase of the capacity of a single machine makes more cables from the generator side to the grid, and the cost also increases.
OBJECTIVES: Aiming at the future large megawatt wind power market, the medium voltage Doubly-Fed electrical system solution is proposed  to increase the higher generation and electricity income of wind farms and reduce the manufacturing cost of wind farms.
METHODS: The technology and economy of medium voltage and low voltage electrical system are compared.
RESULTS: With the gradual increase of single capacity, the economy of medium pressure wind power generation system is getting better and better, and the higher the height of the tower, the better the economy. At the same time, the reduction of the rated current of the generator brings about the reduction of line loss and the increase of power generation. The number of cables is greatly reduced, and the construction cost and difficulty of cable laying will be greatly reduced.
CONCLUSION: In response to the technical trend of large-capacity wind turbines in the future, the medium-voltage wind power generation system has a good application prospect, both from the economic and technical point of view.

Published: April 2024

The vigorous development of new energy has effectively reduced carbon emissions, but it has also brought fluctuating impacts on the carrying capacity of the power grid. In order to improve the voltage stability after integrating new energy sources and promote the scientific consumption of more new energy, this paper proposes the use of Distributed Static Synchronous Compensator (DSSC) devices for flexible and controllable voltage regulation in new energy integration. An improved particle swarm optimization algorithm is then developed to optimize the reactive power considering the regulation of DSSC. The paper conducts power flow calculations based on the DSSC power injection model and establishes a reactive power optimization mathematical model with objectives of minimizing active power loss, minimizing node voltage deviation, and maximizing voltage stability margin in the grid with new energy integration. The improved particle swarm optimization algorithm is utilized to achieve the reactive power optimization. Experimental simulations are conducted using the IEEE 33-node system to analyze the voltage improvement before and after adopting the improved particle swarm optimization algorithm considering the DSSC device in the grid with new energy integration. It is found that the proposed method effectively reduces active power loss and stabilizes voltage fluctuations, demonstrating its practical value.

Authors: Zhao Ning , Li Chengyu
Published: April 2024

INTRODUCTION: It is of great research significance to explore whether China can achieve the "two-carbon target" on time. The MLP model combines nonlinear modeling principles with other techniques, possessing powerful adaptive learning capabilities, and providing a viable solution for carbon emission prediction.
OBJECTIVES: This study models and forecasts carbon emissions in Jiangsu Province, one of China's largest industrial provinces, aiming to forecast whether Jiangsu province will achieve the two-carbon target on time plan and provide feasible pathways and theoretical foundations for achieving dual carbon goals.
METHODS: Based on the analysis of the contributions of relevant indicators using the Grey Relational Analysis method, a comprehensive approach integrating the STIRPAT model, Logistic model, and ARIMA model is adopted. Ultimately, an MLP prediction model for carbon emission variations is established. Using this model, simulations are conducted to analyze the carbon emission levels in Jiangsu Province under different scenarios from 2021 to 2060.
RESULTS: The time to reach carbon peak and the likelihood of achieving carbon neutrality vary under three scenarios. Under the natural scenario of no human intervention, achieving carbon neutrality is not feasible. While under human-made intervention scenarios including baseline and intervention scenarios, Jiangsu Province is projected to achieve the carbon neutrality target as scheduled, attaining the peak carbon goal, however, proves challenging to realize by the year 2030.
CONCLUSION: The MLP model exhibits high accuracy in predicting carbon emissions. To expedite the realization of dual carbon goals, proactive government intervention is necessary.

Published: April 2024

Solar Water Disinfection, known as SODIS, is a treatment method involving the exposure of water to solar radiation (UVA light and heat) to eliminate pathogenic microorganisms. Organic coagulants extracted from Moringa oleifera (T1) and Salvia hispanica (T2) were used in conjunction with the filtration process as auxiliaries. This process included sand filters with particle sizes ranging from 0.25 mm to 0.850 mm and a non-woven geotextile placed at its base. After undergoing the coagulation/flocculation/sedimentation/filtration process, the samples were exposed to sunlight in a solar concentrator using bottles painted on half of their surface (PR) and unpainted bottles (BR). The analyzed parameters included physicochemical properties such as pH, electrical conductivity, turbidity, and apparent color, as well as microbiological parameters, including E. coli and total coliforms. The results of physicochemical analyses demonstrated the superiority of T1 in terms of turbidity and apparent color. Regarding microbiological analyses, they showed the effective removal of E. coli and total coliforms, with 100% inactivation observed in the samples. It was observed that the applied treatment sequence significantly reduced the microbiological load of the samples; however, it cannot be stated with certainty whether the coagulants exerted any influence on this result.
Keywords: coagulants, coliforms, filtration, microorganisms.
Middle Cambrian (Miaolingian) acritarchs from the Flagg Cove Formation, Grand Manan Island, New Brunswick, Canada: stratigraphic implications and possible correlations
Authors: Johnson Susan C. , White Chris E. , Palacios Teodoro , Jensen Sören , Barr Sandra M.
Published: April 2024

The upper Ediacaran to lower Cambrian Castalia Group as originally defined comprises a basal sequence of clastic marine sedimentary rocks assigned to the Great Duck Island and Flagg Cove formations and an upper sequence of mainly mafic volcanic and volcaniclastic rocks of the Ross Island, North Head, Priest Cove, and Long Pond Bay formations. A few previously reported specimens of the long-ranging trace fossil Planolites in the Flagg Cove Formation were not inconsistent with the U–Pb age of 539.0 ± 3.3 Ma age for the Priest Cove Formation or the interpreted intrusive relationship between the Flagg Cove Formation and 535 ± 2 Ma Stanley Brook Granite.During a recent visit, abundant morphologically simple trace fossils, including Planolites, were recognized in strata south of Stanley Beach in Flagg Cove, together with vertically or obliquely oriented trace fossils more than 10 mm in diameter, and probable Teichichnus. The age of this association of trace fossils is post earliest Fortunian. More significantly, grey silty shale interbedded with the sandstone that contains the traces yielded organic-walled microfossils. The microfossils include the acritarch Micrhystridium spp of a type also found in the King Square Formation in the Saint John area. The microfossils suggest a Miaolingian (middle Cambrian) age for the Flagg Cove Formation, requiring that its relationship with the Stanley Brook Granite and Castalia Group needs to be re-examined. it also raises the possibility of correlation with middle Cambrian clastic sedimentary sequences exposed on mainland southern New Brunswick and elsewhere in the region.
A perturbed-Alexander invariant

Published: April 2024

In this note, we give concise formulas, which lead to a simple and fast computer program that computes a powerful knot invariant. This invariant

\rho_{1}

is not new; yet our formulas are by far the simplest and fastest. Given a knot, we write one of the standard matrices,

A

, whose determinant is its Alexander polynomial; yet instead of computing the determinant, we consider a certain quadratic expression in the entries of

A^{-1}

. The proximity of our formulas to the Alexander polynomial suggests that they should have a topological explanation, which we do not have yet.

(\mathcal{I}-\Delta)^{\log}

corresponding to the logarithmic symbol

\log(1 + |\xi|^{2})

, which is a singular integral operator given by

(\mathcal{I}-\Delta)^{\log}u(x) =c_{N}\mathrm{P.V.}\int_{\mathbb{R}^{N}}\frac{u(x)-u(y)}{|x-y|^{N}}\kappa(|x-y|)dy,

where

c_{N}=\pi^{-\frac{N}{2}}

\kappa(r)=2^{1-\frac{N}{2}}r^{\frac{N}{2}}\mathcal{K}_{\frac{N}{2}}(r)

and

\mathcal{K}_{\nu}

is the modified Bessel function of the second kind with index

\nu

. The proof hinges on a direct method of moving planes for the logarithmic Schrödinger operator.

Published: April 2024

In the current realities of business development, modern trends in the innovative development of technological products, and the impact of global intellectual-innovative and techno-technological standards on the activities of industrial enterprises, conducting effective business in our country becomes extremely challenging without the utilization of innovative technologies. These technologies can, to a large extent, ensure the sustainable development of enterprises at the modern level. Scientific-innovative production is an integral component of the production-commercial and intellectual-innovative activities of every industrial enterprise, as it facilitates the renewal of production processes, enhances the quality and consumer value of products, accelerates the speed of sales and product utilization, and increases the efficiency of customization processes based on the individual needs of each consumer. The implementation of scientific-innovative technologies in industrial enterprises objectively prompts transformative changes in their production activities, contributes to the development of the interaction algorithm between the structural units of the enterprise, changes its normative functionality, and advances methodological principles for enhancing the competence of production personnel [1]. An exceptionally important element of this study is the establishment of scientifically substantiated prices for scientific and technical products. In the conditions of the modern competitive environment of technological markets, the price appears as the most crucial tool and method for effective competitive struggle in the global and national markets. The pricing process is, to some extent, a structured system that, from scientific positions, ensures the alignment of commercial-production interests of all existing subjects of the technological market. A scientifically substantiated price level can sufficiently provide the necessary level of competitiveness for the results of production-commercial activities of industrial enterprises and, to some extent, guarantee the break-even nature of their production and market realization of products. Under such conditions, the development and improvement of existing approaches to methods of forming competitive pricing for scientific and technical products become an extremely important and relevant task. The goal is to enhance the efficiency of the production-commercial activities of Ukrainian enterprises, ensuring their production, financial, market stability, and economic security.

Decentralising Climate Governance in the Global South: Lessons from Itezhi-Tezhi and the Kafue Wetlands, Zambia
Authors: Ndambwa Biggie Joe , Moonga Given
Published: April 2024

This article discusses the challenges of decentralising climate governance in the Global South in the context of intensifying climate change. Using qualitative methods of data collection and analysis, we interviewed a total of 112 participants who participated in the study, including traditional leaders, ward councillors, subject-matter experts, government officials and members of the public who took part in focus group discussions. Our results show that devolution, delegation, deconcentration and privatisation have been used as strategies for decentralising climate action in the Itezhi-Tezhi District. However, these methods of decentralisation are affected by several factors, including unclear rules for elected and appointed leaders, which influence the devolution of decision-making responsibilities at the local government level. Regarding delegation, decentralising climate governance is affected by inadequate public participation, particularly in the design and execution of climate initiatives in the Kafue wetlands. Furthermore, this article shows that deconcentration is likely to affect climate governance because the national government has not deconcentrated the units for climate governance from the line ministry to the local authority. Privatisation, which has been an effective way of decentralising climate governance in the Kafue wetlands, has also been problematic due to inadequate community participation. These challenges and opportunities serve as lessons for building resilience in effective decentralised climate governance in the Kafue wetlands. This article adds to the ongoing discourse on the efficacy of decentralising climate governance in the Global South and offers valuable insights for future research in this genre of academic inquiry in Sub-Saharan Africa.

Published: April 2024

Field facilitators are assistants to community self-help groups in the Infrastructure Development program (SPALD-S). TFL plays an important role in the implementation process technically in the field and administratively. TFL provides supervision, assistance and guidance to KSM leaders and communities receiving MCK assistance. Therefore, field facilitators play a very important role in the implementation process of the SPALD-S Infrastructure development program for MCK construction. The Muna Regency PUPR Service, Southeast Sulawesi, still uses manual calculations to calculate data from participant selection results. This takes a long time, and even results in errors in determining TFL that do not meet the requirements, which results in the implementation of activities in the field technically and administratively. For this reason, a systemized process of calculating data from selection results that has been determined by several specified criteria is needed, with a decision support system to determine field facilitators for SPALD-S infrastructure development using the Weighted Product method. The results of calculating 10 data were ranked in order from highest to lowest, namely A1, A8, A4, A9, A6, A2, A5, A10, A7, and A3. The accuracy value obtained was 53.33%.

This paper presents the results of fabricating a model sample of a multilayer coating on a Al2O3 substrate, which consisted of 30 periods of alternately deposited 10.5-nm-thick layers of Ti41Zr41Ni18 and 2.5-nm-thick layers of W. The effect of annealing for 1 h at 500, 600, and 700 °C was studied. Characterization of the phase and structural state of the coating by X-ray diffractometry and small-angle X-ray reflectometry was carried out. It was found that during the annealing process, the tungsten layers in the multilayer composition did not undergo significant changes, and all alterations occur only in the Ti41Zr41Ni18 layers. Annealing affected the thickness of the layers, density, and interlayer roughness. It has been experimentally shown that the phase transformation ”quasicrystal → 2/1 crystalline approximant” is accompanied by an 8.3% volume increase compared to the volume of the quasicrystalline phase, but this does not lead to the destruction of the periodic composition. The multilayer structure proved to be resistant to high temperatures and, despite phase changes, did not lose its bond with the substrate. The used combination of materials and the high annealing temperature did not generate significant internal stresses or mechanical damage. The results obtained in this study allow for the further controlled formation of layered quasicrystal/tungsten microsystems of various designs with different layer thicknesses. The next perspective involves conducting practical tests with plasma to study the radiation-thermal impact.

The purpose of the present study was to find out and show that rapid solidification of the surface layer of AA1933 aluminum alloy melted by irradiation with a high-current pulsed electron beam leads to the development of deformation processes in this layer. This results from thermo-elastic internal stresses arising during irradiation of the
alloy with a pulsed electron beam. The value of residual internal stresses in the irradiation-remelted layer is 43 MPa. Since it is impossible to determine the deformation mechanisms during cooling of the remelted layer by direct methods, conclusions about the deformation mechanisms were made by studying the relief of the irradiated surface. This study shows that deformation processes during irradiation of AA1933 aluminum alloy can develop in different parts of the irradiated surface by different mechanisms. Deformation can be carried out by both dislocation slip and grain-boundary slipping mechanisms.

Published: April 2024

Ergonomics plays an important role in the design and use of agricultural machinery to protect the health and safety of workers. Lack of ergonomic design negatively affects worker discomfort and safety. Therefore, ergonomic design should ensure that workers can work comfortably, maintain correct posture, and minimize the risk of injury. Especially workers using backpack machines are exposed to physical fatigue, posture problems, risk of injury, and ergonomic effects due to vibration and noise. Considering all these, this study was conducted to determine the ergonomic factors (ergonomic analysis of the operator's working posture, operator's fatigue values, noise level, and dust concentration) that the operator is exposed to as a result of different body positions and moving the air diverter hose while using the backpack type blowers used to windrow the kernel+husked nuts falling on the orchard ground during the hazelnut harvest period. According to this, in all three ergonomic risk methods, the operator's body posture was found to be risky, and ergonomic adjustments were needed. Again, the operator's fatigue value, noise level, and dust concentration were obtained as 10.43 kcal min-1, 91.70 dB(A)-106.20 dB(A) (average 98.95 dB(A)), 19.241-21.390 mg m-3-air ( average 20.315 mg m-3-air), respectively. The identification of ergonomic factors is also very important to improve the user experience, prevent occupational accidents, and improve machine performance in general. With the identification of these factors, optimized solutions for the safety and comfort of users will be put forward by adopting a human-centered approach in machine design.

The article studies the amino acid composition of the developed biscuit semi-finished products. When developing the recipe for gluten-free products, special attention was paid to the protein composition of the raw materials and the calculation of the amino acid score, since the lack of a certain amino acid affects the ability of gluten formation during the kneading process. In addition, an unbalanced amino acid composition can cause an imbalance in the human body and negatively affect the functioning of muscles, heart, brain and other organs, leading to diseases. The objectives of the research included the following: determination of the amino acid composition of gluten-free biscuit semi-finished products; analysis of amino acid composition and calculation of the amino acid score of gluten-free biscuit products. The amino acid composition was calculated according to well-known methods, taking into account the chemical composition of food products. During the calculation, the biological value of proteins was assessed, the utility coefficient, the amino acid composition balance coefficient, and the amino acid score difference coefficient were determined. It was established that the developed gluten-free biscuit contained a significant amount of threonine, namely 11.38 g per 100 g of protein. As a result of calculations, it was determined that the first limiting amino acid was tryptophan, the second was the compound «phenylalanine + tyrosine», the shares of which in the amino acid score were 0.12 and 0.90, respectively. An assessment of the complex balance of a gluten-free biscuit semi-finished product showed an insufficient level of balance in human nutrition, but the indicators of individual amino acids compared to the control made from wheat flour were higher, for example, valine by 1.8 times, isoleucine, leucine and lysine by 1.1 times, metheonine + cysteine 2.7 times and threonine 2.8 times.

Published: April 2024

Alzheimer’s Disease (AD), accounting for 60%-70% of dementia cases, is poised to afflict India as the second-largest country by mid-century, as indicated by a recent World Health Organization (WHO) study. The socio-economic landscape in India presents unique challenges, with a population that may not be adequately educated on allocating resources for healthcare beyond the age of 60, especially for conditions like Alzheimer's, which currently lacks a definitive cure. Addressing this impending health crisis necessitates innovative, early diagnosis and cost-effective solutions. This comprehensive review paper explores the potential of utilizing speech data analysis for the early detection of Alzheimer’s Disease (AD), offering a pragmatic approach to mitigate the severity of cases. By harnessing speech data, the aim is to diagnose the condition in its early stages, minimizing costs and enabling timely interventions to impede its progression. Early diagnosis is paramount, as it opens doors to effective treatments and preventative measures. The paper systematically reviews various processes involved in developing a mathematical model for the early detection of Alzheimer’s Disease (AD). It delves into key aspects such as data collection methodologies, pre-processing techniques, feature extraction methods, and diverse classifiers. The intention is to provide a thorough understanding of the intricacies involved in creating an accurate and reliable model for early Alzheimer's detection. In light of Alzheimer’s Disease (AD) representing a substantial majority of dementia cases, this review paper serves as a valuable resource for researchers, healthcare professionals, and policymakers. It fosters a deeper comprehension of potential avenues for leveraging speech data specifically in the context of Alzheimer's. As we confront the impending surge in Alzheimer's cases in India, this comprehensive review work contributes to the foundation of knowledge needed to develop scalable and accessible solutions, making a substantial impact on public health.
PERFORMANCE, HAEMATOLOGY AND SERUM BIOCHEMISTRY OF RABBIT BUCKS FED SUPPLEMENTAL LEVELS OF Saccharomyces cerevisiae
Authors: Istifanus Emmanuel

This study was carried out to investigate the effect of Saccharomyces cerevisiae on growth performance, haematological and serum biochemical indices of rabbit bucks.  Eighteen bucks were used for the study. They were    assigned to three treatment groups with 6 bucks per treatment, replicated 3 times in a completely randomized design for twenty-eight (28) days. The bucks were allowed one week of acclimatization before the commencement of the study, during which they were fed commercial growers diets and forages. The bucks were fed a formulated ration supplemented with S. cerevisiae at 0.0, 0.3 and 0.6g respectively and were coded T1, T2 and T3 respectively. T1served as control. Growth parameters, haematological indices and serum chemistry were measured in the course of the study. The data collected were subjected to analysis of variance (ANOVA) using SPSS version 21, and means were separated using Duncan of same software. The results revealed that S. cerevisae did not have effect (p>0.05) on the growth parameters in the rabbit bucks. This study revealed that Saccharomyces cerevisiae did not have significant effect (p>0.05) in the PCV of bucks in the study as T1, T2 and T3 all had similar (p>0.05) PCV values of 39.00, 39.00 and 41.00% respectively. S. cerevisiae influenced (P<0.05) serum enzymes but did not have significant effect (p>0.05) on total protein, blood urea, ALT creatinine and glucose. In conclusion, dietary supplementation of S. cerevisiae at 0.60% did not have significant effect on growth parameters and most haematological and serum biochemical indices.
