This paper aims to examine the constraints of value management (VM) adoption and implementation in Nigeria’s construction industry with a view to proffering possible measures that could tackle and minimise these constraints and eventually facilitate VM usage in the industry. The study adopts a survey approach. Data collection was based on a structured questionnaire from 300 registered construction professionals across the three most prominent states of northern Nigeria vis: Abuja, Kano and Kaduna States. The data collected were analysed using frequency, percentage, mean score and average index. The study revealed the most-rated constraints as Inadequate knowledge of the benefits of VM; Lack of knowledge and practice of VM; Lack of understanding; and Lack of involvement of specialists from the onset. On the other hand, 39 measures were identified that could tackle the constraints and eventually speed up the adoption of VM practice in the Nigerian construction Industry. The measures were categorised into five groups as related to professionals and professional bodies; government; clients and the community; materials and resources; and construction methodology. The study reveals the three most robust measures capable of tackling the constraints of value management implementation as enforcement of VM techniques by the government on construction projects; anti-corruption campaign; and clients’ emphasis on the inclusion of VM methodologies in their construction projects. This research highlights the constraints of VM adoption in Nigerian construction industry and proffers possible measures that can be taken to facilitate the successful use of VM in the industry. It further categorised the measures as they relate to different stakeholders for easier implementation of actions.

Published: April 2022

This work aimed to examine the ability for phytoaccumulation of Pb in roots and shoots parts of three plant species Taraxacum officinale (TO), Arabidopsis thaliana (AT), and Helianthus annuus (HA) grown in pots containing agricultural soil (AS) contaminated with lead and a combination of AS + organic amendment (kitchen compost). In addition, the bioaccumulation and translocation factors were also evaluated. The high contamination with heavy metals in the soils of the Mantaro Valley, Peru, and the few reported studies using organic amendments with three species led to evaluating the ability of three plant species: Taraxacum officinale (TO – the dandelion), Arabidopsis thaliana (AT – the thale cress), and Helianthus annuus (HA – the sunflower) for phytoaccumulation of Pb in their roots and shoots. Plants seeds were grown in pots containing agricultural soil (substrate A) with lead (764 mg kg-1) and agricultural soil + organic amendment (substrate B – 681 mg kg-1). The treatments were arranged in a randomized design 3 x 2 factorial, with three replicates. Pb contents in plants were increased after Pb exposure. TO (69.28 ± 2.58 mg kg-1; 59.21 ± 1.23 mg kg-1) and AT (47.81 ± 2.18 mg kg-1; 17.29 ± 0.84 mg kg-1) were the species with the highest Pb content in the roots, and HA (53.17 ± 1.15 mg kg-1; 37.72 ± 2.76 mg kg-1) in the shoots for both substrates (A; B). The highest bioaccumulation factor (BF) was registered rather in root than shoot, with values smaller than one for both substrates. The AT species obtained a higher translocation factor (TF) of 2.91, followed by TO (1.65) for substrate A. For substrate B, TO showed a value of 1.57, followed by AT (0.76). The three species showed their ability for remediation of Pb from contaminated soils.

Published: April 2022

Injectable ibuprofen has been formulated as nanoemulsion, prodrug microemulsion, and freeze-dried. However, its application is limited because of solubility, high dosing, and complex formulation. Microemulsion ibuprofen injection is an alternative dosage form that increases solubility and bioavailability. The study aimed to formulate an ibuprofen microemulsion injection that can fulfill the prerequisites for injection preparations with a simple method and simple reconstitution before use. All combinations of the oil and aqueous phases were formed using the self-emulsification technique. The optimum stability was estimated on particle size, polydispersity index (PDI), and zeta potential at 5°C, 25°C, and 40°C for 120 days. Based on the minimum amount of Tween 80, drug loading, and the highest transmittance value, the optimal microemulsion formula was obtained at a concentration of 2.8% (1:1 combination of olive oil and medium-chain triglyceride oil), 11.2% Tween 80, 2.8% propylene glycol, and 83.2% water for injection. The optimal formula has a droplet size of 16.7 ± 11.2 nm, a zeta potential of 0.8 mV, and a PDI of 0.196. The formula was stable at 45°C storage for up to 14 days, at 25°C, and at 5°C, steady at 120 days based on droplet size diameter of 21.27 ± 0.00 nm, zeta potential -1.3 ± 0.10 mV, and PDI 0.38 ± 0.02. The optimum formula by simple reconstitution without additional isotonization has fulfilled the requirements for injection preparation. It was concluded that the ibuprofen microemulsion with a combination of medium-chain triglyceride oil and olive oil could form a stable microemulsion and has the potential to be developed as a pharmaceutical preparation in the form of injectable ibuprofen.

This study aims to analyze and describe corruption forms, causes, and prevention. This study uses a qualitative approach through a case study of the Riau Provincial Government. This study shows the findings that there have been many cases of corruption committed by state civil servants and state officials, based on a comparison of data sources from the Corruption Eradication Commission (Indonesia KPK), police, and courts from 2017 to 2020. Based on the results and the identification of corruption cases, there were various findings according to the types, modes, and causes of corruption. Therefore, they can be used as empirical data to formulate strategies to prevent corruption. The researchers conclude that the Riau Provincial Government has demonstrated skills and success in preventing corruption, and the level of corruption can be suppressed and reduced significantly every year. In increasing efforts to prevent corruption, the researcher suggests five stakeholders collaborate (Pentahelix) and strengthen e-government governance. With the role and dimensions of Penta helix cooperation and the presence of IT-based governance, it will strengthen efforts to prevent corruption sustainably. This research creates a novelty in the paradigm that corruption will be prevented optimally if understood in depth, including its form, typology, and causes so that prevention can be carried out comprehensively, with an approach not limited to legal provisions, administration, and technology. However, the most critical task is forming a mentality of honesty and loyalty as state apparatus in providing services to the community and the state.

Extra to water, tea is the broadly consumable hot beverage in the biosphere. People drink more tea than coffee, cold drinks, dairy products, and alcohol combined. Availability does not effectively order the dried plant pieces, which are utilized to make tea. Numerous cases of food adulteration have been recorded in many countries, including India. This has taken to the creation of a new discipline of science, known as ‘green criminology’, to compensate violations of food law. Over the years, new techniques for identifying food adulteration have been developed Here we reviewed different standard DNA based molecular techniques to analyze their performance in identifying tea constituents. Originally, these were sensory techniques, which proved unreliable. Later, physical analysis of the product was done based on data on the label and microscopic evaluation. Later methods, based on the identification of lipids and proteins, were also not accurate due to biochemical changes during processing. These problems provoked scientists to get an interest in the potential of DNA testing. Due to the stability of DNA and the universal applicability of DNA-based methods for all cells, they are ideal for use in practice. Currently, the most reliable test for detecting food adulteration is Bar-HRM, as it is a highly sensitive and specific technique. Broad scale endorsement of the plant’s DNA barcoding may require systems that spot the journey brings about point of view of common plant species names and character for separate firmly close gatherings.

Published: April 2022

A review has been done on the formulation of mathematical models for designing anaerobic batch reactor for the producing of biogas from solid wastes. Using material balance analysis, the design parameters, especially biokinetic behavior of solid
wastes are studied. Hydrolysis constants and reaction orders at both low total solids concentrations and high total solids concentrations were thoroughly reviewed by initial rate method. Population growth model and first order hydrolysis model are also studied. It has been found that if sufficient reaction time is given, in terms of reaction kinetics, the hydrolysis process in kitchen waste fermentation can be described as a first order reaction. An attempt is done by utilizing the biodegradable kitchen waste collected from Aryabhatta hostel, NIT Agartala for generation of biogas and demonstrating the possibilities of energy recovery. A simple anaerobic digester has been fabricated to capture the generated biogas. To produce methane as a clean fuel the use of cow dung as substrate is studied to ferment the kitchen wastes.

Multi-Task Learning using Frequency-Warped Spectrum for Detecting Out-of-breath Speech
Authors: Sahoo Sibasis , Dandapat Samarendra
Published: April 2022

This paper presents methods for detecting out-of-breath speech (OBS) under the shortness-of-breath condition due to physical load. It uses constant Q transform (CQT) for warping frequency spectrum non-linearly, which focuses on spectral saliencies of speech signal under the said condition. The existing works using deep neural networks (DNN) have spectrograms or prosodic features as input to detect the OBS speech. Two target labels, neutral and OBS, are commonly used for training DNN models. The labels, however, do not reflect the true exertion level in a speaker. In this work, a transfer-learning approach is proposed for estimating the physical exertion level. An open-source DNN model, which is trained on environmental sounds, is used for the same purpose. A multi-task learning (MTL) framework is applied for jointly learning the binary class labels and the exertion levels. The results show that the spectrogram with non-linear frequency warping performs better than its linear counterparts. Furthermore, with MTL, the classification performance F1-score improves by 3.54% and 12.67% over the single task learning (STL) using CQT-spectrogram and Mel-spectrogram, respectively.

The reverse sural artery flap (RSAF) was first described approximately four decades ago in 1983 by Donski and Fogdestam [1] and has since been used frequently for reconstruction of soft tissue defects in the distal part of the leg. Coverage of soft-tissue defects of the ankle and foot is often challenging. The distally based sural fascio-cutaneous flap is useful for reconstructing the lower leg, ankle, heel, and foot but has rarely been evaluated in paediatric patients. The objectives of this study were to assess the reliability of this flap in children, to get a global experience with the sural flap in our department of plastic and reconstructive pediatric surgery, and to describe the complications. Material and methods: A distally based sural fascio-cutaneous flap was used to cover soft-tissue defects of the ankle and foot in 5 paediatric patients between 2018 and 2021. The median age of patient at surgery was 6 years old. The most frequent mechanism of soft tissue defect was trauma caused by vehicular accident (open fractures) crush injuries, lacerated wound. Results: One of the 5 flaps was a cross leg sural flap, 4 recovered well without necrosis, only one developed partial necrosis requiring excision and skin grafting. The other complications where an early postoperative complications: partial or total necrosis of the flap late complications including impaired touch sensation over the flap and donorsite. Discussion: The distally based sural fascio-cutaneous flap is a method of choice for covering soft-tissue defects of the ankle and foot in paediatric patients. This reliable flap spares the major blood vessels and has a good blood supply. When there is exposure of a vital structure, distal sural flap is the best indication for coverage in a traumatic soft-tissue defect. The use of a distally based sural fascio cutaneous flap is not free from delayed complications most of them at the donor site.

Aims and Objectives: To assess the utility of Neutrophil-Lymphocyte Ratio (NLR), Platelet-Lymphocyte Ratio (PLR) & Ultrasound findings to predict Severe Cholecystitis. To identify an NLR, PLR cut off value to discriminate between simple and severe cholecystitis. METHODS: A prospective observational time bound study conducted with sample size of 100 patients from December 2019 to January 2021. Severe cholecystitis was defined as cholecystitis complicated by secondary changes like haemorrhage, gangrene, emphysema, abscess, perforation, carcinoma. NLR, PLR values were calculated from absolute neutrophil count and absolute lymphocyte count. All patients underwent Ultrasound abdomen by the same Radiologist, findings were grouped into three categories, Luminal, Mural and Pericholecystic changes. Intraoperative findings, Histopathological examinations were also taken into account. Data was analysed using SPSS Software Version 22. Receiver Operating Characteristic Curve analysis was employed to identify optimal NLR, PLR Cut off values and to predict Combined accuracy of NLR, PLR and Ultrasound findings to predict severe cholecystitis. Results: In our study, 23% patients had severe cholecystitis. Mean age was 46 years. 65% were females. Presence of calculi and presence of multiple calculi was higher in patients with severe cholecystitis (p value 0.25) calculated using Chi square test. Ultrasound findings of Luminal, Mural and Pericholecystic changes were also higher in severe cholecystitis (p value <0.001). Mann whitney test showed mean NLR, PLR higher in severe cholecystitis. A Cut off NLR of 3.75 had a sensitivity of 100%, specificity of 77.92%. Length of hospital stay in patients with severe cholecystitis was longer. CONCLUSION: NLR of 3.75 is a cut off value to predict severe cholecystitis and prolonged length of hospital stay. Combined Predictive Accuracy of NLR, PLR, Ultrasound findings was 91%. Ultrasonography is a reliable, specific diagnostic tool.

Published: April 2022

The congenital anomalies of breast, especially the polymastia (supernumerary breast) and polythelia (supernumerary nipple), can have varied presentations, associated renal anomalies, and pathologies arising from them. The axillary polymastia is a variant of ectopic breast tissue (EBT). Ectopic breast tissue can undergo the same physiological and pathological processes as the normally located breast. The incidence of fibroadenoma developing in ectopic breast is reported as a rare entity, the most common being the carcinoma. Here we report a case of fibroadenoma developing in ectopic breast tissue located in axilla.

Background: Hemorrhoids is a very common anorectal condition distinct as the symptomatic enlargement and distal displacement of normal anal cushions. Several factors have been claimed to be associated with hemorrhoidal development, including prolonged straining and constipation. Several treatment methods along with the Milligan-Morgan procedure are applied in treating hemorrhoids. Aim of the study: The aim of this study was to compare the effectiveness and outcomes of stapled hemorrhoidopexy and conventional Milligan Morgan procedure in treating hemorrhoids. Methods: This comparative observational study was conducted at the Department of Surgery, Rajshahi Medical College, Rajshahi, Bangladesh during the period from January 2019 to December 2019. In total 100 patients with grade 3 or 4 hemorrhoids who fulfilled the criteria were included in the study subjects. In total 50 patients were denoted as group A patients who underwent stapled hemorrhoidopexy and the other 50 patients denoted as group B underwent conventional open (Milligan Morgan Procedure) hemorrhoidectomy. Patients were reviewed immediately after surgery and at 1, 3, 6 weeks, and 6 months post-operatively. All data were processed, analyzed, and disseminated by MS Office and SPSS programs as per need. Results: In this study, the mean ± (SD) duration of hospital stay was 2.88 ± 0.48 days in group B which was extremely significantly higher than that (1.77 ± 0.12 days) of group A (P <0.0001). After 6, 12 and 24 hours of surgery the pain scores in group A were significantly lower than those in group B (P-Values: 0.001, 0.005, and 0.014 respectively). The mean (±SD) patient satisfaction score was found extremely significantly higher in group A (4.13 ± 0.61) than that of group B (3.27 ± 0.57) where the P-value was <0.0001. The mean (±SD) ‘time taken to return to work in days was found extremely significantly lower in group A (9.06 ± 2.43 days) than that of group B (16.66 ± 2.79 days) where the P-value was .......

Bacterial meningitis is responsible for important global pediatric mortality. Empiric treatment initiated to reduce the fatal outcomes, are based on the common pathogens encountered and sensitivity pattern of those. But in the recent years emergence of rare bacterial pathogens is being witnessed, which may or may not be handled by the empiric treatment. Globicatella sanguinis is a rare cause of acute meningitis. We report this case to present its rare isolation in cerebrospinal fluid sample. Besides this, we also emphasize the fact that identification based on phenotypic methods alone can misidentify many bacteria which may affect specific antibiotic prescription.

Published: April 2022

Polycystic ovary syndrome (PCOS) is a common clinical condition that manifests during adolescence with menstrual irregularities, acne and hirsutism. Patients with PCOS, especially with hyperandrogenic phenotype, are exposed to several cardiometabolic risk factors that increase their chance for developing hypertension. Little is known about the association between serum testosterone level and blood pressure in young women with PCOS but many of the symptoms associated with PCOS have been shown to be associated with increases in blood pressure, such as increases in body mass index and the presence of metabolic syndrome, with its accompanying insulin resistance and type 2 diabetes. We report the case of an 18-year-old female patient with no specific history who presented with edema of the lower limbs at the time of menstruation and in whom the clinical examination showed high blood pressure with signs of hyperandrogenism and hypertriglyceridemia in the biological work-up, leading to the search for a PCOS. After a well-adapted management the patient kept a well-balanced blood pressure with a lipidic balance which was normalized only by hygienic and dietetic rules.

Dermatofibrosarcoma protuberans (DFSP) is a rare soft tissue tumor that is locally aggressive and has a high rate of recurrence after surgical intervention. We repot a case of a 73-year-old man presented an abdominal mass evolving over 30 years. Physical examination revealed a multinodular lesion of 12x10 cm, slightly fixed to the deep tissues. A skin biopsy was performed. Histopathological examination rconfirmed the diagnosis of dermatofibrosarcoma protuberans. CT imaging was suggestive of a subcutaneous supra-fascial mass of 67x89x98 mm, infiltrating the left rectus abdominis muscle. The patient underwent surgical resection of the tumor and the muscle’s fascia. The lateral margins were between 5 to 13 cm. The deep resection margin was at 0,1 cm. The mainstay of treatment for DFSP is complete surgical excision with histologically negative margins. Radiation should be considered as an adjuvant to resection if margins are positive.

Different restoration options are available for replacing a single missing tooth on the posterior region; full coverage fixed dental prostheses, implant-supported crown and inlay-retained fixed dental prostheses (IRFDPs). In fact, this last achieve an esthetically and functionally good result, and present almost reversible treatment given that, the preparation is conservative preserving dental and gingival tissues. Thus, it can be concluded that all-ceramic inlay retained fixed dental prostheses are an esthetic option that can be recommended as viable short- or middle-term minimally invasive restoration. Case selection, material choice, preparation design and luting procedures are determinant factors of success. This paper aimed to discuss through a case report, the material and the preparation design of all-ceramic inlay-retained fixed dental prostheses.
