Introduction:

Aerosols and droplets contaminated with bacteria and blood are produced during ultrasonic scaling. Measures to control aerosol contamination in dental clinics are recommended by the Centers for Disease Control and Prevention. This study aimed to evaluate the efficacy of preprocedural boric acid (BA) mouthrinse in reducing bacterial contamination in dental aerosols generated during ultrasonic scaling.

Materials and Methods:

This was a randomised clinical trial in 90 systemically healthy subjects (25-55 yrs) diagnosed with chronic periodontitis who were allocated into three groups of 30 subjects each to receive, Group A - 0.12% chlorhexidine (CHX), Group B - 0.75% BA and Group C-water, as a preprocedural rinse for 1 min. The aerosol generated while performing ultrasonic scaling for 30 min was collected at three locations on blood agar plates. Incubation of the blood agar plates at 37°C for next 48 h for aerobic culture was performed and subsequently colony-forming units (CFUs) were counted.

Results:

CFUs in Group A were significantly reduced compared with Group B (P < 0.001). When we compare CFUs in all the three groups, CFUs in Groups A and B were statistically significantly reduced compared with Group C (P < 0.001). Furthermore, it was also observed that the assistant's chest area had lowest CFUs whereas patient's chest area had highest.

Conclusion:

This study recommends routine use of preprocedural mouthrinse as a measure to reduce bacterial aerosols generated during ultrasonic scaling and that 0.12% CHX gluconate is more effective than 0.75% BA mouthwash in reducing CFUs count.

Published: September 2021

Background:

Biomechanical preparation of root canal can damage root dentin leading to the formation of dentinal cracks which can eventually lead to fracture and failure of the treatment.

Aim:

The aim was to investigate the incidence of dentinal defects in root canals prepared with ProTaper Universal, ProTaper Gold, and Hyflex electric discharge machining (EDM) rotary file systems using handheld USB digital microscope.

Materials and Methods:

One hundred and fifty extracted mandibular premolar teeth with single canal were randomly divided into five groups (n = 30). Group 1: unprepared (negative control). Group 2: canal preparation done with nickel–titanium hand files (positive control), Group 3: canals prepared with ProTaper Universal rotary system, Group 4: canal preparation done with ProTaper Gold rotary system, and Group 5: canals prepared with Hyflex EDM rotary system. The specimens were sliced at 3 mm, 6 mm, and 9 mm from the apex with a slow-speed saw under water cooling. Digital images of each section were captured at ×40 magnification with the aid of a microscope. Two independent evaluators assessed the images for the presence of dentinal defects. The number of dentinal defects was recorded and Chi-square test was used for statistical analysis (P < 0.05).

Results:

The number of specimens presenting dentinal defects was as follows: Group 3; ProTaper Universal – 9/30 (30.0%), Group 4; ProTaper Gold – 2/30 (6.7%), and Group 5; Hyflex EDM – 1/30 (3.3%). No defects were detected in the negative and positive control groups (Group 1 and Group 2).

Conclusion:

ProTaper Universal showed the highest percentage of defects in comparison to ProTaper Gold and Hyflex EDM.

Published: September 2021

Power pad designing, misalignment reduction, safety, automation, living object
detection (LOD), and foreign object debris (FOD) detection are the key
challenges in the commercialization of the high voltage wireless charging of
Electric Vehicles (EV). The interruption from unwanted and sensitive foreign
objects such as metal objects and living objects over the charging pads is an
immense challenge for the static wireless charging of EV. In this manuscript,
the problem of interference due to foreign objects and living objects has been
analyzed, and an innovative laser- and sensor-based FOD detection method is
proposed and verified by developing a prototype setup. Modeling and analysis of
the effects of foreign objects have been performed using Finite Element Analysis
(FEA) in Ansys Maxwell® environment. The analysis compares the consequence of
the presence of foreign objects on the wireless charging power pad. The proposed
method utilizes laser light and sensor for the detection and two-dimensional
signal processing for the elimination of FOD. The proposed method is compatible
with all types of static wireless charging systems without interrupting the
power transfer and power circuit. The proposed system has been analyzed and
compared with the various available FOD detection techniques. The feasibility of
the proposed system has been assessed with the help of an on the bench hardware
prototype implementation in the lab environment.
Influence of the Sleeve Teeth Shape Parameters on the Shifting Process of Automated Manual Transmission for Electric Vehicles
Authors:   Beijing University of Technology, China, Wu Bin , Chen Cunxi ,   Beijing University of Technology, China
Published: September 2021

Electric vehicles equipped with automated manual transmission (AMT) provide the potential for improving the power and economic performance. However, due to the direct connection between the driving motor and the input shaft of the transmission, the higher moment of inertia at the input of AMT would lead to a poor shift quality. Based on the dynamic analysis of the engagement process of AMT without synchronizer, the dynamic model of the engagement process was established by using AMESim software. Through the analysis of the engagement process, it was concluded that the higher contact force and longer meshing duration under reverse contacting engagement condition is the main reason for the shift difficulty. In order to improve the shift quality, the influences of the sleeve teeth shape parameters of reverse contacting chamfer on the engagement process were analyzed and the simulation validation was performed. The simulation results showed that reducing the width and increasing the angle of the reverse contacting chamfer can effectively reduce the engagement duration and the contact force impulse, although the vehicle jerk was increased slightly, which did not exceed the most stringent criterion value of 10 m·s-3. Optimization of teeth shape parameters of reverse contacting chamfer can be considered to improve the shift quality of the electric vehicle equipped with an AMT.

Earthquake is one of the most frightening and destructive phenomena of nature. The northeast India region, as well as its adjoining South-Asian neighbours including Myanmar and Bangladesh, is tectonically and seismically most active. The region categorized under the highest level of seismic hazard potential: Zone V, of the seismic zonation map of India, has experienced nearly 22 large (M ≥7.0) and two great earthquakes (M S ∼ 8.7) in the past 130 years. All these earthquakes caused wide-spread damage over the region. In the recent past, with rapid urbanization combined with a significant population rise as compared to those times when these great/large earthquakes occurred, the seismic vulnerability index has increased manifold. The situation demands widespread dissemination of seismic hazard and preparedness information via community engagement and highlighting on potentially tragic consequences of earthquakes by conducting extensive mock drill exercises & earthquake awareness programmes. In this paper, the role and efforts of the statuary bodies in the region, such as National Disaster Management Authority (NDMA) and CSIR – Northeast Institute of Science and Technology (NEIST) and societal program of Academy of Scientific and Innovative research, to mitigate and minimize seismic hazard by extensive dissemination of earthquake information, via scientific scenario and impact assessment, is holistically compiled.
Analysis of the Spanish real estate market as investment opportunity
Authors: Astudillo Cobos Diego Gonzalo
Published: September 2021

After the bubble burst, the real estate sector has become a very attractive market for funds or large investors. Financial entities were going through a very difficult situation and these opportunistic funds found the best time to invest in real estate. One of the most important funds in this market is Blanckstone, it has a large portfolio of assets and is considered the largest landlord in Spain. At the end of 2013, several indicators were favorable for the real state sector. However, since the last quarter of 2019, this recovery already showed signs of exhaustion and the contraction was greater this year since productive activity in most sectors was paralyzed. However, several authors agree that a market collapse will not occur, since they are since current conditions are better compared to those that occurred during the bursting of the bubble, for example the private sector presents a better financial position and there is no excessive building.
1, 2, 3, Fork: Counter Mode Variants based on a Generalized Forkcipher
Authors: Andreeva Elena , Bhati Amit Singh , Preneel Bart , Vizár Damian
Published: September 2021

A multi-forkcipher (MFC) is a generalization of the forkcipher (FC) primitive introduced by Andreeva et al. at ASIACRYPT’19. An MFC is a tweakable cipher that computes s output blocks for a single input block, with s arbitrary but fixed. We define the MFC security in the ind-prtmfp notion as indistinguishability from s tweaked permutations. Generalizing tweakable block ciphers (TBCs, s = 1), as well as forkciphers (s = 2), MFC lends itself well to building simple-to-analyze modes of operation that support any number of cipher output blocks.Our main contribution is the generic CTR encryption mode GCTR that makes parallel calls to an MFC to encrypt a message M. We analyze the set of all 36 “simple and natural” GCTR variants under the nivE security notion by Peyrin and Seurin rom CRYPTO’16. Our proof method makes use of an intermediate abstraction called tweakable CTR (TCTR) that captures the core security properties of GCTR common to all variants, making their analyses easier. Our results show that many of the schemes achieve from well beyond birthday bound (BBB) to full n-bit security under nonce respecting adversaries and some even BBB and close to full n-bit security in the face of realistic nonce misuse conditions.We finally present an efficiency comparison of GCTR using ForkSkinny (an MFC with s = 2) with the traditional CTR and the more recent CTRT modes, both are instantiated with the SKINNY TBC. Our estimations show that any GCTR variant with ForkSkinny can achieve an efficiency advantage of over 20% for moderately long messages, illustrating that the use of an efficient MFC with s ≥ 2 brings a clear speed-up.
Exploring Differential-Based Distinguishers and Forgeries for ASCON
Authors: Gerault David , Peyrin Thomas , Tan Quan Quan
Published: September 2021

Automated methods have become crucial components when searching for distinguishers against symmetric-key cryptographic primitives. While MILP and SAT solvers are among the most popular tools to model ciphers and perform cryptanalysis, other methods with different performance profiles are appearing. In this article, we explore the use of Constraint Programming (CP) for differential cryptanalysis on the Ascon authenticated encryption family (first choice of the CAESAR lightweight applications portfolio and current finalist of the NIST LWC competition) and its internal permutation. We first present a search methodology for finding differential characteristics for Ascon with CP, which can easily find the best differential characteristics already reported by the Ascon designers. This shows the capability of CP in generating easily good differential results compared to dedicated search heuristics. Based on our tool, we also parametrize the search strategies in CP to generate other differential characteristics with the goal of forming limited-birthday distinguishers for 4, 5, 6 and 7 rounds and rectangle attacks for 4 and 5 rounds of the Ascon internal permutation. We propose a categorization of the distinguishers into black-box and non-black-box to better differentiate them as they are often useful in different contexts. We also obtained limited-birthday distinguishers which represent currently the best known distinguishers for 4, 5 and 6 rounds under the category of non-black-box distinguishers. Leveraging again our tool, we have generated forgery attacks against both reduced-rounds Ascon-128 and Ascon-128a, improving over the best reported results at the time of writing. Finally, using the best differential characteristic we have found for 2 rounds, we could also improve a recent attack on round-reduced Ascon-Hash.
Boomeyong: Embedding Yoyo within Boomerang and its Applications to Key Recovery Attacks on AES and Pholkos
Authors: Rahman Mostafizar , Saha Dhiman , Paul Goutam
Published: September 2021

This work investigates a generic way of combining two very effective and well-studied cryptanalytic tools, proposed almost 18 years apart, namely the boomerang attack introduced by Wagner in FSE 1999 and the yoyo attack by Ronjom et al. in Asiacrypt 2017. In doing so, the s-box switch and ladder switch techniques are leveraged to embed a yoyo trail inside a boomerang trail. As an immediate application, a 6-round key recovery attack on AES-128 is mounted with time complexity of 278. A 10-round key recovery attack on recently introduced AES-based tweakable block cipher Pholkos is also furnished to demonstrate the applicability of the new technique on AES-like constructions. The results on AES are experimentally verified by applying and implementing them on a small scale variant of AES. We provide arguments that draw a relation between the proposed strategy with the retracing boomerang attack devised in Eurocrypt 2020. To the best of our knowledge, this is the first attempt to merge the yoyo and boomerang techniques to analyze SPN ciphers and warrants further attention as it has the potential of becoming an important cryptanalysis tool.
PLCrypto: A Symmetric Cryptographic Library for Programmable Logic Controllers
Authors: Yang Zheng , Bao Zhiting , Jin Chenglu , Liu Zhe , Zhou Jianying
Published: September 2021

Programmable Logic Controllers (PLCs) are control devices widely used in industrial automation. They can be found in critical infrastructures like power grids, water systems, nuclear plants, manufacturing systems, etc. This paper introduces PLCrypto, a software cryptographic library that implements lightweight symmetric cryptographic algorithms for PLCs using a standard PLC programming language called structured text (ST). To the best of our knowledge, PLCrypto is the first ST-based cryptographic library that is executable on commercial off-the-shelf PLCs. PLCrypto includes a wide range of commonly used algorithms, totaling ten algorithms, including one-way functions, message authentication codes, hash functions, block ciphers, and pseudo-random functions/generators. PLCrypto can be used to protect the confidentiality and integrity of data on PLCs without additional hardware or firmware modification. This paper also presents general optimization methodologies and techniques used in PLCrypto for implementing primitive operations like bit-shifting/rotation, substitution, and permutation. The optimization tricks we distilled from our practice can also guide future implementation of other computationheavy programs on PLCs. To demonstrate a use case of PLCrypto in practice, we further realize a cryptographic protocol called proof of aliveness as a case study. We benchmarked the algorithms and protocols in PLCrypto on a commercial PLC, Allen Bradley ControlLogix 5571, which is widely used in the real world. Also, we make our source codes publicly available, so plant operators can freely deploy our library in practice.

The prefrontal cortex (PFC), mediating executive brain functions is impaired in epilepsy. Allium sativum (AS) anti-seizure potential on the PFC of experimentally-induced epilepsy was investigated. Forty-eight male Wistar rats (200-250g) were randomized into six groups. Control (2mL/kg distilled water); AS only (100mg/kg); LiCl+PC (lithium chloride, 127mg/kg, and pilocarpine, 30mg/kg); LiCl+PC+AS100mg/kg and LiCl+PC+AS300mg/kg received LiCl+PC and 100mg/kg AS and 300mg/kg AS respectively; LiCl+PC+SV received LiCl+PC and sodium valproate (10mg/kg). Treatments lasted for 21 days, behavioural tests then preceded sacrifice. Brain tissues were excised, fixed in 10% neutral buffered formalin for demonstration of PFC cytoarchitecture and glial fibrillary acidic protein (GFAP) expression. Neurotransmitters were also assayed. Walling and rearing frequencies reduced significantly (p<0.05) in the LiCl+PC group compared to control. Glutamate and acetylcholine levels increased in all groups except AS only, while gamma-aminobutyric acid, dopamine, serotonin and norepinephrine levels increased in the LiCl+PC+AS100mg/kg, LiCl+PC+AS300mg/kg and LiCl+PC+SV groups compared to the control. Cytochrome C oxidase and glucose-6-phosphate dehydrogenase activities significantly increased (p<0.05) in all groups, while nitric oxide levels increased in the LiCl+PC+AS300mg/kg and LiCl+PC+SV groups compared to the control. Cytoarchitecturally, the LiCl+PC PFC showed neurodegenerative features, increased GFAP expression, while the treated groups showed preserved neurons and mild astrogliosis. Conclusively, AS showed neuroprotective potentials against LiCl+PC-induced neuronal degeneration, mitigated reactive PFC astrogliosis. However, AS did not lower glutamate and other neurotransmitter levels.
God help us: Spirituality and religiosity amid corona pandemic in Pakistan
Authors: Ali Kausar , Minxing Huang
Published: September 2021

This research discusses the response of the religious people to the corona pandemic in Pakistan. The study aims to answer why the Islamists refused to cooperate with the state authorities in its struggle against the pandemic? This study is based on the theory of existential security which states that natural calamities and disasters always increase religiosity in the people. This study is based on analysing all the existing primary and secondary sources in the form of books, research articles and government reports. The discussion in this paper is based on the qualitative analysis of all the existing sources. This study has argued that the Islamists refused to support the state policymakers because they firmly believed that the virus emerged because of Allah’s wrath. The study has also found that the response of the Tablighi Jamaat (henceforth TJ), other religious organisations, and clerics amid the coronavirus in the country was indeed a religious coping strategy. This strategy is commonly used by people whenever they face a life-threatening situation. The study suggests that Pakistan could not resist the Islamists because resisting them could cause severe problems in the country.

TSH-secreting pituitary adenoma: a rare cause of hyperthyroidism Central hyperthyroidism is noted in a 35-year-old man with recurrent panic attacks. Thyroid-stimulating hormone-secreting pituitary adenoma (TSH-secreting adenoma) is found to be the underlying etiology. A pituitary adenomectomy is carried out, with regression of the symptoms and hyperthyroidism. TSH-secreting adenomas are rare and cause hyperthyroidism due to autonomous TSH secretion. In addition to hyperthyroidism, dysfunction of other pituitary axes and neurological problems due to local compression may also be present. Biochemically, TSH adenoma is characterized by elevated levels of thyroid hormones without suppression of the TSH concentration. After analytical interference has been ruled out, additional biochemical and radiological investigations are necessary in the differential diagnosis and to establish diagnostic certainty. Neurosurgical resection is the cornerstone of the treatment, although radiotherapy and somatostatin analogs may also be considered.

An investigation was conducted to assess the effect of fertilizers, Azospirillum and compost (kitchen waste manure) on chilli (Capsicum annum var. frutescence) cv. Pusa Jwala at Babasaheb Bhimrao Ambedkar University, Lucknow (U.P.) during winter season of 2016-17. The twelve treatments were evaluated in a randomized block design with three replications. Results showed that the highest fresh weight of fruits per plant (575.73g), highest fruit yield (9212 g plot-1 and 4.26 t ha-1) was recorded with 50% RDF + kitchen waste manure (25 and 50 days after transplanting)] followed by RDF 50% + Azospirillum (soil application at transplanting). However, the quality characters in terms of total soluble solids (7.4 %), ascorbic acid (116.67mg/ 100 g fruit), total sugars (2.5 %), reducing sugars (1.7 %) and non-reducing sugars (0.8 %) of fruits were observed better with Azospirillum treatment along with RDF i.e. RDF 50% + Azospirillum (soil application at transplanting)]. It was also seen that combined effect of RDF and organic manures proved superior to RDF (100%) sole application in respect of yield and quality of fruits. The lowest values of yield and quality parameters were recorded in control treatment.

A field experiment was conducted at Agricultural Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, Uttar Pradesh during Kharif season of 2018. The experiment consisted of six combinations of different tillage methods and crop establishment practices with four-time replicated under randomized block design. Zero tillage [direct seeded rice - wheat (Full CA; anchored residue of rice and wheat + mungbean residue retention)]showed significantly higher plant height, number of tillers m-2and chlorophyll content as compared to the other treatments, while the lowest values of these parameters were observed under conventional tillage (rice-wheat without residue). There was a steady rise in plant height and number of tillers with age of plant under all the treatments. The yield and its attributes were significantly higher under zero tillage [direct seeded rice - wheat (full CA; anchored residue of rice and wheat + mungbean residue retention)] followed by treatments zero tillage [direct seeded rice - wheat (full CA; anchored residue of rice and wheat)]. While, the poor yield was reported in conventional tillage (rice-wheat without residue). Zero tillage [direct seeded rice - wheat (full CA; anchored residue of rice and wheat + mungbean residue retention)] increased nutrient use efficiency in term of partial factor productivity of applied NPK in rice crop.

In the present study, wrapping and packaging materials were evaluated for their capacity to decrease the decay losses of guava fruits during storage under ambient conditions (18-22OC and 75-80% RH) at Tej Narayan Banaili College, T.M. Bhagalpur University, Bhagalpur during the year 2014-2016. Results revealed that post-harvest decay loss can be minimized significantly through proper wrapping or packaging of fruits for storage. Fruits wrapped with heat-shrinkable low density polyethylene film (LDPE, 25 µm thick), or packed up to 30 days of storage in corrugated fibre board (CFB) boxes exhibited low decay losses of 11.9 and 22.8 per cent, respectively. In general, the fruit loss due to fungal attack increased with increasing duration of storage. Altogether 7 fungal species were found associated with rotten fruits during the storge. Botryodiplodia theobromae, was the most prominent post-harvest rotting agent causing 37.5% fruit loss. Colletotrichum gloeosporioides, Pestalotia psidii and Alternaria alternata showed 30.8, 25.5 and 16.8% fruit decay losses, respectively. Aspergillus niger (10.6%) Penicillium expansum (7.0%) and Rhizopus stolonifer (4.5%) caused least per cent decay losses of guava fruits.

A field experiment was conducted at instructional cum research farm, SASRD, Nagaland University during 2017-19 to study the effect of integrated nutrient management on leaf nutrient status, growth, flowering and yield of tissues culture banana (Musa sp.) cv. Grand Naine under foot hill condition of Nagaland. The experiment was laid out in randomized block design with eight treatments and three replications. Among the various treatments, application of 100% NPK + 15kg FYM + biofertilizer showed the best result for vegetative growth like pseudostem height (177.7 cm), pseudostem girth (65.4 cm), number of functional leaves (14.8), phyllochron (7.0 days) and leaf nutrient status (2.66% N, 0.23% P and 2.89% K) at shooting stage. Nitrogen content in index leaf increased gradually at 5 MAP (2.33 to 3.10%) and there after declined at shooting stage (2.14 to 2.72%) in all treatments. Similarly, higher phosphorus content (0.18 to 0.25%) in index leaf was noted at 3 MAP while, higher potassium content at 5 MAP (2.76 to 3.44%) and at shooting stage (2.28 to 3.10%). The reproductive growth, such as days for emergence of inflorescence (239.0 days), days from planting to harvesting (360.6 days), number of hands (10.8), bunch weight (27.6 kg) and yield (85.17t ha-1) were highest with application of 75% NPK + 15kg FYM + 1kg V.C + 1kg P.M + biofertilizers. Integrated nutrient management in improving the growth and yield was found to be effective as compared to use of organic manure or inorganic fertilizers alone.

Impact of the climate variables was studied in terms of selected plant attributes, viz., leaf area, RGR etc. Study showed that elevated temperature as well as elevated CO2 individually and in combination had significant positive effect on growth and development, rate of photosynthesis, and water use efficiency of the Chenopodium album. Rate of transpiration and stomatal conductance increased marginally in plants grown at elevated temperature, but a marked decrease was evident at elevated CO2 individually and in combination with elevated temperature as compared that in plants grown in ambient conditions in the Chenopodium album. No significant changes were observed in relative water content and relative stress injury under any of the Chenopodium album. Treatments changes were evident with respect to the activity of antioxidant enzymes and nitrate reductase and peptide banding pattern using SDS-PAGE. This research was conducted to examine the joint effects of increased temperature and elevated CO2 level onChenopodium album (C3 weed). Results from this experiment suggested that rising (CO2) could alter physiochemical response for growth and development of Chenopodium album and it is well defined competitors with different crops in current changing climate conditions.

In order to examine the current status of soil acidity in Meghalaya, representative soil samples (n= 497) were collected (during 2015-2016) from across the state and analyzed for soil acidity and associated parameters. Averaged across the samples, pH of the soils was found to be very strongly acidic (4.94). Nearly 20 % of the soils had pH below 4.50, 59% below pH 5.0 and 80% below pH 5.50. Only 3.4% of the samples recorded pH more than 6.0. East Khasi Hills District had the maximum percentage (95.1%) of strongly acidic soils (pH ≤ 5.50) while Garo Hills had the least (50.2%). All other districts recorded more than 85% of the strongly acidic soils. Average exchangeable acidity, exchangeable Al and effective CEC were found to be 1.60, 1.27 and 3.86 meq/100g soil, respectively. Mean base saturation was recorded below 60%. Aluminium saturation (percentage of effective CEC being occupied by exch. Al) ranged from 1.5 to 79.7% with its mean value being as high as 33%. Principal component analysis provided three PCs with Eigen values >1 and together they explained 83.2 % of the variance in total dataset. The soil acidity in Meghalaya is on rise, with 80.2% of its soils being strongly acidic (pH ≤ 5.50) in contrast to the previous reports of 53% soils being strongly acidic. This calls for widespread adoption of soil acidity ameliorative measures in agriculture of Meghalaya, Northeast India.
