Abstract
The keyword searching algorithm plays a vital role in cloud computing Architecture. Here, the searching technique is applied as a tool to encrypted data set which is outsourced. This technique works well, by either directed on multi keyword findings with exact match or one keyword search with fuzzy logic with a result of true or false. Though the existing techniques come across sensible difficultyin execution upon the encrypted data set, in the execution of multiple keyword based searching, keyword correction is difficult to achieve. To overcome with this problem, we construct a highly efficient, multiple corrections in keyword searching algorithm using ranking scheme. Multiple corrections like spell checks and errors. In the existing system of Author Wang and others scheme, they were unable to address the aforementioned problems, But in our method of multiple keyword searching technique, the Fuzzy Gramm algorithm helps to detect and handle the spelling errors by making a function call. Additionally the keywords with similar ancestry can be found by making use of stemming procedure. Alongside with thatrank keyword is used to achieve accurate checking with matched text file content. Thus the proposed approach enhances security and reliability to the maximum extent compared to the existing system.

Abstract
In the present scenario, the demand for agriculture is increasing abruptly due to the population in the world. In agriculture, irrigation plays a major role. As it requires electricity supply to irrigate the field, farmers find it an additional expense towards the electricity cost and also it is challenging to provide the uninterrupted supply to farmers. Though our government provides subsidies, the demand for electricity throughout the world is increasing. Especially as we tend to rely on agriculture for our daily life and considering the hardship faced by the farmers, nowadays people tend to move towards solar power but the existing grid connected system may lead to high cost, need of more space, and needs proper maintenance. The use of DC pumps overthrows the struggles of farmers and to pave a way to increases agricultural practices. This system consist of array of 3 panels connected to the DC motor of 0.75 kW. The use of DC motor assists in storing the power generated by the system and can be used during night time or in case of emergency situation, providing uninterrupted power supply. This system serves the important advantage to the environment that it reduces CO2 emission as it eliminates the use of fuel for pumps to operate. As the system is designed autonomous, it also reduces space occupancy. The panel setup is placed in an appropriate location so that it could receive more radiation, as a result generates maximum power. The parameters like power, power quality and pumping rate has also been analyzed under varying atmospheric conditions under specific period of time. Thus this system provides the more efficient way to utilize the solar power and to generate maximum energy for use.

Abstract
Most of the urban areas in India depend on Government water supply for their daily usage. The amount of water supply will be limited and provided in a short period of time by the Government. According to the climate and environmental changes the amount of water will be varied. Now many private companies have emerged in the field of water supply to sell water to gain huge profit. But still Government water supply is the main source for common people in urban areas of India. Most of the water connections are given to the individual home by plastic or steel pipes through underground or overground. It is very easy for a person to steal the water from the pipeline illegally. Others cannot identify the theft easily and they will be cheated. Consequently, water availability/supply for the homes in that area will be reduced. A system has been proposed in the paper to find and stop the water theft in an area using the sensors and IoT technology. This system can also identify the leakage of pipes anywhere in the line.
Estimation of the buried pipeline displacement using distributed fibre optic sensing: An experimental study
Authors: Alarifi Hamzh , Mohamad Hisham 
Published: March 2021

Abstract
Pipe displacement (bending) is one of the most prominent risks caused by the soil movements in the landslide areas. The lateral soil movement causes damages to the buried pipelines, which might explode due to leakage of flammable materials. Employing fibre optic sensors to monitor the buried pipes can maintain the integrity of piping systems and the surrounding environment. The fibre optic sensor has already demonstrated its capabilities to provide a continuous monitoring system for the structures. This paper aims to evaluate the buried pipeline displacement caused by the lateral soil movement. Brillouin Optical Time Domain Analysis (BOTDA) is used to measure the strain values from the fibre optic cable. A small physical model is used to demonstrate the bending of High-density polyethylene (HDPE) pipe under the ground movement. This paper concludes that the fibre optic sensor could be employed to evaluate the horizontal and vertical displacements of the buried pipeline.

Abstract
This paper focuses on the experimental study to determine the relationship of slope length on runoff depth and runoff coefficient. Based on the thorough review of different plot sizes (lengths) for soil loss estimation, the slope of the current experimental plots was designed with an angle of 22.78° from horizontal. The plots were grouped into Plot A (1 m wide x 1 m slope long), Plot B (1 m wide x 2 m slope long) and Plot C (1 m wide x 3 m slope long). Homogenous soil samples were used for all the 3 experimental plots and a tipping bucket rain gauge with automatic data logger was installed at the experimental plot for rainfall intensities collection for the individual rainfall events. Runoff volumes were recorded for the individual rainfall events for determination of runoff coefficients. The rainfall intensities are grouped into ⩽30 mm/h, 30-60 mm/h and ⩾60 mm/h. It was found that the shorter plot (Plot A) has the highest runoff coefficients of 96.34%, 69.89% and 96.26% for 3 different precipitation groups ⩽30 mm/h, 30-60 mm/h and ⩾60 mm/h, respectively. Based on results, the longest plot (Plot C) shows that an increase in mean values of 33.59%, 38.30% and 49.45% as the intensity increased from ⩽30 mm/h to ⩾60 mm/h. From this study, it can be concluded that comparatively longer slope length tends to result in lower runoff depth.

Abstract
Lately, it has been observed that buildings are becoming daring in their design, with forms and structures that appears to defy the law of gravity. The architecture discipline has been deployed to create eye-catching, even startling forms isolated in space that serves multiple purposes from authoritarian state-building to symbols of development, to “must-see” objects driving tourist to a particular place. These dramatic, monumental assemblies are not always well-received, however, with public outrage frequently directed toward their undesirable impacts on or lack of consideration toward the built context of a place. The building is not only a functional structure in any urban area but rather an intervention in the public space that remain there for many years or became an iconic landmark for someone to remember. The design of these buildings is not entirely based on the skill of the architect. Possibly influenced by the desires and tastes of the clients somewhat influenced by the practical constraints of the budget. Likewise, within those parameters, the creativity and even personality of the architect often shines through. The paper employed an exploratory techniques coupled with a descriptive analysis from printed materials as the framework to gather the written criticism of the projects that has been built. Through the pictorial and repertory grid applied in the investigation, this examines the essence of architecture design from the modern era until the present day. The findings from pictorial analysis showed that resemblance of the façade of the building symbolize the common objects and simple form found in daily life.

Abstract
River pollution, which is mainly due to excessive drainage of untreated domestic greywater, has becoming a serious concern in both poor and developing areas like Sarawak in the current years. Realizing the vital role of Sarawak rivers, the need to improve the level of pollution, demand for clean freshwater resources, as well as to save cost on household water supply, the greywater generated daily from every household needs to be pretreated for reuse, otherwise, discharged. This further demands for cost-effective pretreatment technology for domestic and residential use. This research, therefore, analyzes the efficiency of a low-cost bio-filtration system which utilizes agricultural wastes, namely rice husk and coconut coir, as bio-filter media to improve the quality of greywater effluent samples in terms of total suspended solids (TSS) and turbidity removals. This paper presents the extended results obtained from the previous research work using the same fabricated pre-treatment system, which consists of six main units i.e. wastewater storage tank, water feed tank, pre-sedimentation tank, bio-filter, post-sedimentation tank and treated water storage tank. The system is operated for six hours to complete several cycles of treatment. At every one-hour interval, both TSS and turbidity levels of the wastewater samples are recorded and the removal performances are evaluated and analyzed. Positive outcomes are attained from this research study such that the rice husk system is able to reduce the TSS and turbidity levels by 49.06% i.e. from 53.00 mg/L to 27.00 mg/L with an average rate of 4.33 mg/L.hr, as well as 57.79% i.e. from 41.70 FNU to about 17.60 FNU, at a rate of 4.02 FNU/hr respectively. Besides, the coconut coir bio-filtration system achieves TSS removal efficiency of 49.70% i.e. from 65.60 mg/L to 33.00 mg/L at mean rate of 5.43 mg/L.hr, and 63.10% turbidity removal i.e. from 48.40 FNU to 17.86 FNU, at 5.09 FNU/hr respectively.

Abstract
In this work, we show the route to obtain thermoplastic based composites with an enhanced thermal conductivity that was achieved by using exfoliated hexagonal boron nitride (hBN) particles as a filler material. Reports on composites with bulk or nano hBN showed, that while increasing the filler load improves thermal properties it could aggravate the composite melt rheology and mechanical properties. On the other hand, exfoliated hBN particles compared to bulk or nanopowder hBN could provide even better thermal properties with no degradation in composite mechanics, which was shown for epoxy. Taking into account the above, we obtained exfoliated hBN particles by ultrasound treatment in isopropyl alcohol and then used them as a filler in polypropylene based composites to increase the thermal conductivity. The composites with 29% wt. of exfoliated hBN showed a thermal conductivity of 0.721 W m−1 K−1 which is 4 times higher than for pristine polypropylene.

Published: March 2021

Abstract
The amounts of nuclear materials in the LiCl-KCl salt in pyroprocessing have to be analyzed to prevent the diversion of the nuclear material. An alternative method to the chemical analysis has been pursued, and laser-induced breakdown spectroscopy (LIBS) is one candidate. In the present work, an in situ and quantitative analysis method of electro-recovery (ER) salt was proposed and demonstrated by using LIBS combined with dipstick sampling. Two types of simulated salt samples were prepared: ER salt sample and salt obtained from the dipstick sampling, and pulsed neodymium-doped yttrium aluminum garnet (Nd:YAG) laser with a wavelength of 532 nm was focused on the salt to generate plasma. The plasma emission was measured by using an Echelle spectrometer with a resolution of 0.01 nm in conjunction with an Intensified Charge-Coupled Detector camera. The U and other rare earth peaks in the spectra were identified. The best Limit of Detection and Root Mean Square Error of Calibration of U were 38 ppm and 0.0203 wt%, respectively. Our work shows that the U in the pyroprocessing ER salt can be monitored with LIBS.

Interventions to Improve Post-Detoxification Treatment Engagement and Alcohol Recovery: Systematic Review of Intervention Types and Effectiveness
Authors: Livingston Nicholas , Ameral Victoria , Hocking Elise , Leviyah Xenia , Timko Christine 
Published: March 2021

AbstractAimsMost inpatient alcohol detoxification patients do not seek treatment post-discharge, which increases the risk of relapse and re-hospitalization. To date, there have been no efforts to synthesize the evidence supporting the broad range of available interventions for this critical transition. The current study is a systematic review and evaluation of interventions designed to promote treatment engagement and recovery following alcohol detoxification.MethodsThe initial literature search yielded 6419 articles, published since 1999, from PubMed, CINAHL, PsycINFO, Psychology & Behavioral Sciences Collection and PsycARTICLES databases, 49 of which were eligible for full review. Data extraction included in-depth evaluation of intervention types, study and research design features, reported outcomes and study quality/bias indicators. All articles were coded by independent raters and final results were obtained through consensus.ResultsInterventions included medical/medication, psychological/psychosocial, technological, mutual-help and combined approaches. On average, medical/medication interventions were less, and psychological/psychosocial and technological interventions were more likely to demonstrate efficacy with respect to treatment engagement and recovery. There was significant variability in study quality/bias but no significant differences across intervention types. Studies differed considerably across measured outcomes, internal and external validity, in/exclusion criteria and documentation of co-occurring psychiatric disorders.ConclusionOver half of studies reviewed reported empirical support for the intervention(s) evaluated. Although findings slightly favor non-medical interventions, the variability in study design and quality/bias requires more rigorous follow-up research. Recommendations from this review may guide future implementation and intervention development, which are critically needed to improve post-detoxification care and outcomes for patients with alcohol use disorder.
Does Having Deep Personal Relationships Constitute an Element of Well-Being?
Authors: Hooker Brad 
Published: March 2021

Abstract
Deep personal relationships involve deep mutual understanding and strong mutual affection. This paper focuses on whether having deep personal relationships is one of the elements of well-being. Roger Crisp put forward thought experiments which might be taken to suggest that having deep personal relationships has only instrumental value as a means to other elements of well-being. The different conclusion this paper draws is that having deep personal relationships is an element of well-being if, but only if, the other people involved have qualities that merit affection for these people.

Abstract

Background
Lipofilling has become popular as a treatment to improve aging-related skin characteristics (eg, wrinkles, pigmentation spots, pores, or rosacea). Different additives such as platelet-rich plasma (PRP) or stromal vascular fraction (SVF) have been combined with lipofilling to increase the therapeutic effect of adipose-derived stromal cells (ASCs).

Objectives
The aim of this study was to examine the hypothesis that mechanically isolated SVF augments the therapeutic effect of PRP-supplemented lipofilling to improve facial skin quality.

Methods
This prospective, double-blind, placebo-controlled, randomized trial was conducted between 2016 and 2019. In total, 28 female subjects were enrolled; 25 completed the follow-up. All patients received PRP-supplemented lipofilling with either mechanically isolated SVF or saline. SVF was isolated by fractionation of adipose tissue (tSVF). Results were evaluated by changes in skin elasticity and transepidermal water loss, changes in skin-aging-related features, ie, superficial spots, wrinkles, skin texture, pores, vascularity, and pigmentation, as well as patient satisfaction (FACE-Q), recovery, and number of complications up to 1 year postoperative.

Results
The addition of tSVF to PRP-supplemented lipofilling did not improve skin elasticity, transepidermal water loss, or skin-aging-related features. No improvement in patient satisfaction with overall facial appearance or facial skin quality was seen when tSVF was added to PRP-supplemented lipofilling.

Conclusions
In comparison to PRP-supplemented lipofilling, PRP-supplemented lipofilling combined with tSVF does not improve facial skin quality or patient satisfaction in a healthy population. PRP-supplemented lipofilling combined with tSVF can be considered a safe procedure.
