Published: April 2022

Growth-promoting bacteria Azospirillum brasilense, used as an inoculant in corn culture, can be severely affected by the exposure temperature, with a lethal effect above 35°C, when cultivated alone under laboratory conditions. Such effects may limit the associative interaction between plant-bacteria, with reduced inoculation efficiency, resulting in a lower growth rate of the plant and an increase in oxidative stress. Thus, the objective of the research was to evaluate the efficiency of the inoculation process with A. brasilense in seeds and in the initial growth of seedlings of two corn cultivars submitted to different temperatures. Were utilized corn hybrids seed Syn 488 and Syn 505. The experimental design was completely randomized in a 2 x 4 factorial scheme (with and without inoculation of A. brasilense x 4 sowing temperatures: 20, 25, 30, and 35ºC), with four replications. The inoculation efficiency in corn seedlings submitted to different temperatures was evaluated through the following tests: germination, first count, seedling length and dry weight. In addition, responses at the biochemical level of the interaction (temperatures x inoculation) for the content of photosynthetic pigments and hydrogen peroxide (H2O2), antioxidant enzymes and lipid peroxidation were evaluated. The inoculation with A. brasilense changed the morphological and biochemical responses of corn seedlings, and the inoculation process was efficient for all temperatures tested. The best results were under temperatures 25, 30, and 35°C. Plant and bacteria when exposed to temperature conditions (30°C inoculated) showed a significant increase in plant biomass and activity of antioxidant enzymes.

This study verified the efficiency of ovitraps combined with Saccharopolyspora spinosa and Bacillus thuringiensis israelensis for monitoring Aedes aegypti and Aedes albopictus in laboratory and field conditions. In the laboratory, for A. aegypti, there was no difference in eggs number between treatments and grass infusions. For A. albopictus, the average of eggs was higher in the grass infusion. In the dry season, there was no difference in the average of eggs between treatments and control. In the rainy season, grass infusion resulted in a higher egg density, in both areas. Ovitraps combined with biolarvicides are efficient in dengue vector monitoring.

Published: April 2022

Social media has significantly influenced modern lifestyle and the way in which most of the industries operate their business. Social media data refers to the contents created by users during their social interactions in the form of text, sound, visuals, etc. It has now evolved as the major source of information for different industry verticals like retail, marketing, advertising, tourism, hospitality, education, etc. The huge volume of data resulted in the necessity for better and efficient procedures for personalized information retrieval. Traditional data mining and information retrieval techniques based on content-based and/or collaborative filtering proved computationally costly and less scalable against the volume it must deal with. Adoption of clustering techniques is a potential solution for this problem as it can minimize the amount of data required to be managed in industrial applications like recommender systems. This empirical research focuses on evaluating multiple clustering algorithms with the goal of finding an ideal solution for clustering numerical data extracted from social media sources. Three different publicly available datasets with varying number of attributes and records from tourism domain are used for the experiments conducted as part of this work
Grid-connected photovoltaic system to mitigate momentary voltage dip based on the balance between the active and reactive powers

Published: April 2022

With a great potential yet to be explored in Brazil, the grid-connected photovoltaic system, besides supplying the active power, can also contribute to improve the voltage level grid providing reactive power. Therefore, this work proposes to use a Grid-Connected Photovoltaic System (GCPVS) equipped with a control that uses the automatic voltage regulator (AVR) to balance the injection of the active and reactive powers, thus softening the short-duration voltage variation, more specifically the momentary voltage dip. For this purpose, the GCPVS was connected in part of a real distribution grid that attend the block 1106 South of Palmas city, state of Tocantins, northern region of Brazil. It is shown that the active and reactive power delivered to the grid can be controlled to help the power quality of the main grid during a disturbance. During a short-circuit situation, the active power is reduced, freeing up space from the inverter capacity for maximum supply of reactive power, in this way, helping the main grid to return to an adequate voltage level. The simulation results show that such voltage profile improvement is possible. Therefore, they confirm that photovoltaic systems, even though considered small, can also provide ancillary services to the low voltage distribution grid during abnormal conditions, adding to the actions normally performed by conventional power plants

E3 Ubiquitin Ligase Riplet Is Expressed in T Cells and Suppresses T Cell–Mediated Antitumor Immune Responses
Authors: Iwamoto Asuka , Tsukamoto Hirotake , Nakayama Hideki , Oshiumi Hiroyuki
Published: April 2022

The E3 ubiquitin ligase Riplet mediates retinoic acid–inducible gene-I polyubiquitination and is essential for viral-induced expression of type I IFNs in dendritic cells and macrophages. The function of Riplet in innate immunity has been well demonstrated; however, its role in adaptive immunity during the antitumor immune response is unclear. In this study, we examined the role of Riplet in the T cell–mediated antitumor immune response. Riplet was expressed in T cells and upregulated in CD8+ T cells in response to TCR-mediated stimulation. Furthermore, PR domain containing 1, eomesodermin, and killer cell lectin-like receptor G1 expression was increased in effector CD8+ T cells by Riplet knockout in vitro, which suggests that Riplet is involved in the effector function of CD8+ T cells. Our results indicated that Riplet deficiency augmented the antitumor response of MO4 (OVA-expressing melanoma)–bearing mice treated with OVA peptide-pulsed dendritic cells. Moreover, both CD4+ and CD8+ T cells played important roles in Riplet-mediated augmentation of the antitumor immune response. In tumor-draining lymph nodes, the Th1 response was promoted, and the induction of OVA-specific CD8+ T cells and IFN-γ production were enhanced by Riplet deficiency. Furthermore, the IFN-γ response and OVA-specific cytotoxicity of CD8+ T cells in tumor tissue were augmented by Riplet deficiency. The expression of Cxcl9fluorescence-minus-one and Cxcl10 mRNA was also enhanced in the tumor microenvironment by Riplet knockout, consistent with the augmented recruitment of CTLs. Overall, we clarified a function of Riplet in T cells, which is to suppress the antitumor immune response through modulating Th1 and CTLs.

Our respiratory system is vital to protect us from the surrounding nonsterile environment; therefore, it is critical for a state of homeostasis to be maintained through a balance of inflammatory cues. Recent studies have shown that actively transcribed noncoding regions of the genome are emerging as key regulators of biological processes, including inflammation. lincRNA-Cox2 is one such example of an inflammatory inducible long intergenic noncoding RNA functioning to fine-tune immune gene expression. Using bulk and single-cell RNA sequencing, in addition to FACS, we find that lincRNA-Cox2 is most highly expressed in the lung and is most upregulated after LPS-induced lung injury (acute lung injury [ALI]) within alveolar macrophages, where it functions to regulate inflammation. We previously reported that lincRNA-Cox2 functions to regulate its neighboring protein Ptgs2 in cis, and in this study, we use genetic mouse models to confirm its role in regulating gene expression more broadly in trans during ALI. Il6, Ccl3, and Ccl5 are dysregulated in the lincRNA-Cox2–deficient mice and can be rescued to wild type levels by crossing the deficient mice with our newly generated lincRNA-Cox2 transgenic mice, confirming that this gene functions in trans. Many genes are specifically regulated by lincRNA-Cox2 within alveolar macrophages originating from the bone marrow because the phenotype can be reversed by transplantation of wild type bone marrow into the lincRNA-Cox2–deficient mice. In conclusion, we show that lincRNA-Cox2 is a trans-acting long noncoding RNA that functions to regulate immune responses and maintain homeostasis within the lung at baseline and on LPS-induced ALI.

The germinal center (GC) response is essential for generating memory B and long-lived Ab-secreting plasma cells during the T cell–dependent immune response. In the GC, signals via the BCR and CD40 collaboratively promote the proliferation and positive selection of GC B cells expressing BCRs with high affinities for specific Ags. Although a complex gene transcriptional regulatory network is known to control the GC response, it remains elusive how the positive selection of GC B cells is modulated posttranscriptionally. In this study, we show that methyltransferase like 14 (Mettl14)–mediated methylation of adenosines at the position N6 of mRNA (N6-methyladenosine [m6A]) is essential for the GC B cell response in mice. Ablation of Mettl14 in B cells leads to compromised GC B cell proliferation and a defective Ab response. Interestingly, we unravel that Mettl14-mediated m6A regulates the expression of genes critical for positive selection and cell cycle regulation of GC B cells in a Ythdf2-dependent but Myc-independent manner. Furthermore, our study reveals that Mettl14-mediated m6A modification promotes mRNA decay of negative immune regulators, such as Lax1 and Tipe2, to upregulate genes requisite for GC B cell positive selection and proliferation. Thus, our findings suggest that Mettl14-mediated m6A modification plays an essential role in the GC B cell response.
Problemi medico-legali dell'autodisposizione del proprio corpo

Published: April 2022

Gli autori ritengono che vi siano alcuni aspetti della terapia medico-chirurgica, in particolare quelli inerenti la sterilizzazione irreversibile, quelli che comportano il cambiamento di sesso e quelli che concernono i malati terminali, che inducono riflessioni che trascendono lo studio medico-legale dell'applicazione dell'artt. 5 C. C e 32 Costituzione per toccare il campo più ampio e difficile della finalità e dei limiti della scienza medica. In tale contesto gli autori cercano dapprima di puntualizzare la problematica inerente la "diminuzione permanente dell'integrità fisica" per passare quindi all'analisi critica della natura del consenso individuale e dei suoi rapporti con il cosiddetto consenso sociale ai trattamenti medico-chirurgici sopra menzionati.
La fondazione dell'obbligo morale al trattamento dei pazienti con infezione da HIV

Published: April 2022

L'articolo esamina la questione etica, sorta in ambito medico con la comparsa della infezione da HIV, del rifiuto da parte di alcuni medici a curare i pazienti con tale infezione a causa del rischio personale. Ci si è chiesti se esiste una fondazione dell'obbligo da parte del medico a curare e a quale livello essa si situi: a tale scopo sono stati esaminati testi giuridici, deontologici e la letteratura etica. In conclusione gli autori evidenziano l'insufficienza della legislazione e della deontologia a fondare tale obbligo. Sul versante etico l'esame dei diversi modelli desumibili dalla letteratura consente di individuare nel modello etico delle virtù e ancor più nel personalismo ontologico il riferimento essenziale per fondare il dovere del medico a curare in vista della tutela del bene integrale del paziente.

Background and Aims: Diarrheal diseases caused by bacterial pathogens are widespread and they result in morbidity and mortality of a lot of people yearly. The aim of this study was to assess the role of the environment, health workers and food handlers as reservoirs of Vibrio cholerae, and other diarrhea causing bacteria. Methods: Healthcare workers were proportionally selected and multistage sampling technique was adopted in selecting food handlers for the study. A total of 374 participants consisting of health workers and food handlers were recruited. Socio-demographic and clinical information were collected using questionnaires, while stool and environmental samples were also collected. Results: More female 55.9 % than male 44.1 % participated in the study and the mean age of participants was 38.7 ± 10.9. A significant number of participants identified poor hygiene practices as the major cause of diarrhea. V. cholerae O1 serotype was not detected in any of the environmental samples nor stool samples of both food handlers and health workers. However, V. cholerae (Non O1/Non O139) was isolated from the stool samples of food handlers and health workers in Kano State implying that they could be serving a source of the continuous dissemination of the pathogen. Other bacterial pathogens that are aetiology of diarrhea including Salmonella spp. Escherichia coli, Klebsiella oxytoca, and Enterobacter spp. were also isolated. Conclusion: It is therefore imperative that food handlers and health workers undergo periodic health checks to ensure they are free of pathogens they could easily transmit through food or to patients.

Published: April 2022

Background and Purpose:

Mucormycosis and Aspergillosis square measure the foremost frequent fungal infections caused by these filiform fungi. Coinfection is scarce and incorporates a poor prognosis. The commonest presentation of invasive fungal infection (IFI) is rhinocerebral involvement. It ordinarily affects immunocompromised patients.

Case report:

A 55-year-old post-COVID male patient with uncontrolled Diabetes Mellitus developed swelling and chemosis in the left eye. In plain CT orbit, mucosal thickenings were seen in the ethmoid, sphenoid, left frontal, and left maxillary sinuses without any erosions or extensions. Nasal endoscopy showed black-brown overgrowth on the left middle turbinate. Biopsy revealed growth of both Mucor and Aspergillus. The patient was treated for Diabetic Ketoacidosis along with Amphotericin-B for anti-fungal management and showed significant improvement and is stable.

Conclusion:

It is probably the first rare case of coinfection with Mucormycosis (Rhizopus spp.) and Aspergillosis (Aspergillus flavus). Early diagnosis is a major advantage in management. The multidisciplinary approach of such cases is invaluable. The implementation of higher diagnostic methods including PCR in the diagnosis at all tertiary care facilities. A refined selection of post-COVID cases in higher numbers and cautious collection and processing of patient specimens will certainly attribute to higher chances of a definitive diagnosis and an early initiation of specific and efficient treatment.
The Occurrence and Management of Adverse Skin Events due to Continuous Glucose Monitoring
Authors: Lee Jung Hwa
Published: April 2022

The use of continuous glucose monitoring (CGM) for blood glucose control is increasing and is effective in changing treatment methods and improving lifestyle by identifying problems in blood sugar patterns. However, adverse skin events are increasing due to the insertion of invasive tools or attachment of sensors to the skin for 14 days for intermittent CGM. These adverse events can be the reason for the discontinuation of CGM. Therefore, this paper aims to determine methods to identify and manage skin irritation and side effects caused by CGM accessories.

Background and Purpose:

Cross-sectional area (CSA) is the most important parameter to study peripheral nerves by high-resolution ultrasonography. The aim was to acquire normative data of CSA of the main upper and lower limb nerves in the Indian population.

Methods:

CSA of nerves was determined in 100 healthy volunteers at 11 predetermined sites: median and ulnar at the wrist, mid-forearm, elbow; radial (spiral groove); tibial (popliteal fossa, medial malleolus); common peroneal (CPN, fibular head) and sural (lateral malleolus).

Results:

The mean age of participants was 40.7 ± 13.0 years (range: 18-79). Fifty were < 40 years of age. The mean height, weight and BMI were 161.5 ± 8.3 centimeters (range: 145—179), 58.6 ± 10.1 kilograms (range: 32-90) and 22.4 ± 3.2 kilogram/square meter (range: 14.03-30.44), respectively. The median and ulnar nerve measurements were non-uniform throughout its course, and the CSA was largest at the elbow and ulnar groove, respectively. With advancing age, there was a significant difference for median and ulnar nerves at the wrist (median P = 0.002, ulnar P = 0.009) and tibial nerve (popliteal fossa, P = 0.045, medial malleolus, P = 0.005), CPN (P = 0.047). Men had greater CSA of upper limb nerves and tibial nerves at popliteal fossa (P < 0.05) as compared to women. A positive correlation was noted with weight.

Conclusion:

It is apt for every defined population to have its own set of normative data of CSA as it varies with ethnicity, age, and the built of individuals. We provide a valuable set of CSA data for nerves in the Indian population, which can be used for comparison while investigating peripheral nerve disorders.
New Treatment Modalities in Hemophilia

Published: April 2022

Hemophilia is a single gene disorder and as a genetical coagulation system problem it is a life-long bleeding disorder. Even though routine treatment modalities as plasma-derived and then recombinant factor concentrates available for last 50 years, unmet needs is continuing for hemophilia therapy. Gold standart treatment is regularly prophylactic FVIII/FIX infusions. However, life-long and frequent intra-venous infusions become medical burden for patients and families. New agents as enhanced half-life (EHL) factor concentrates and non-factor therapies which are able to be used subcutaneously are very hopeful. In this review, EHL factor concentrates, FVIII mimetic agents and re-balancing therapies will be discussed. Although celluler gene therapy is very hopeful and successful phase-3 studies are reported, gene therapy for hemophilia will not be mentioned in this review.
Polityka pisarstwa historycznego i polityka literatury. Hayden White i Jacques Rancière czytają Ericha Auerbacha

Published: April 2022

Politics of Historical Writing and the Politics of Literature – Hayden White and Jacques Rancière Read Erich Auerbach Hayden White and Jacques Rancière used Erich Auerbach’s approach to the history of realistic European literature to construct their own theoretical discussions of historical and literary writing. White thus formulated the concepts of a figural relationship, modernist and figural realism, while Rancière critically commented on the undemocratic historiography of the Annales school and sought egalitarian writings in Western literature. White’s and Rancière’s readings of Auerbach will be used to compare their two theoretical approaches. The purpose of this analysis will be, first, to critically compare some of their contributions, and second, to incorporate Rancière’s claims into the English-language debate on the theory of history. I will try to answer the following question: how in their commentaries on the works of Auerbach White and Rancière defined the relationship between politics and historical and literary writing; how they articulate the politics of historical writing (White) and the politics of literature (Rancière).

Historiography of the Polish Transformation? A Draft to a Summary

There have been several canonical studies on the historiography of the political history of the systemic transformation in Poland still constitute a point of reference for researchers today. At the same time, however, the dynamic growth of the source base and the increasing popularity of post-structuralist scientific trends resulted in the fact that the research perspective characteristic of this canon is aging rapidly. The analysis and comments formulated in this text are an attempt at balancing the strengths and weaknesses of the historiography of the political history of the systemic transformation to date and an attempt to indicate how it potentially could develop further.

The main aim of this research was to establish a minimum series length when crime opportunities are not distributed at random. In addition, the behaviour of two methods of assessing the accuracy of a geographic profiling algorithms were analysed. The second objective was to analyse the existence and properties of the buffer zone in the created model. For the purpose of this research, a simulation was used. Data showed significantly different behaviour in the two tested methods of assessing the accuracy of geographic profiling, with hit score percentage being the significantly more sensitive measurement. The tests allowed all of the effects attributed to the buffer zone to be obtained, despite the fact that it was not included in the model itself. For series as long as nine offences accuracy in non-random conditions was similar to series length five and uniform distribution of opportunities.

Archival services of the Polish Air Force during the Second World War

The Historical Commission, established in Paris in March 1940, can be considered the first archival cell of the Air Force, however, it never became operational. Records of the Air Force were evacuated in June 1940 to the United Kingdom by office workers, and deposited in Blackpool. In September 1940, the Records Liquidation Commission of the former Air Force Command in Paris was established, and existed until March 1941. After that time, its activities came to a halt. Based on its structures, in December 1941, the Aviation Historical Bureau was established. Its tasks included gathering, processing, and storing documents. In January 1945, the Bureau was incorporated into the Archival and Museum Services, and in July, the Bureau was transferred to Dunholme Lodge, where it remained until 1948, when it terminated its operations. In the final years of its existence, the Historical Bureau mainly dealt with processing and classifying the collections. Eventually, the records and memorabilia kept by the Air Force were deposited in the Sikorski Historical Institute in London.
Sobre la nueva reforma de la educación matemática: invitación a un debate, 2
Authors: Mena Lorca Arturo
Published: April 2022

La reforma de las matemáticas escolares que comenzó hacia 1960, sorprendió a Chile sin la preparación que se requería. Posteriormente, se avanzó, sin embargo, en los diversos ámbitos, y, ya desde fines del siglo pasado, se comenzó una nueva revisión, tanto de la institucionalidad como del currículo. Los comienzos de la pandemia encontraron a Chile con una serie de medidas de envergadura ya en fase de implementación, y con un currículo completamente revisado durante la última década. Se pudo haber pensado que correspondía ahora recomenzar el ciclo y, pacientemente, evaluar y enmendar lo que correspondiera, pero hay una circunstancia más apremiante: una nueva reforma educacional, diferente, amplia, profunda e inexorable, ya está llegando. En esta parte del escrito examinamos más de cerca la reforma de los años 60 y sus consecuencias inmediatas, procuramos sacar algunas lecciones, examinamos de manera crítica algunos criterios que se ponen en juego y una notoria falta de sintonía entre algunos actores, y, además, tratamos de situar ese análisis vis a vis con la responsabilidad que nos cabe como personas concernidas con la educación de la matemática.
A Methodology to improve Goodness of Fit when Replicating Empirical Data utilizing Artificial Intelligence
Authors: Moreb Ahmad A. , Alharbi Naif Nahi
Published: April 2022

Scientists and practitioners frequently resort to replicating empirical data when testing the validity of scientific theories or testing hypothesis. Commonly known probability distribution (Normal, Binomial, Exponential, etc.) are habitually assumed to fit the empirical data. To avoid complicated probability distributions, analysts find themselves tolerating poor values for the goodness of fit. In this paper, a methodology is introduced for replicating empirical data that succeeded in obtaining goodness of fit close to 100% compared to 87% goodness of fit using a known probability distribution. Moreover, Artificial Intelligence (AI) is developed spatially for this research to enhance accuracy further.

Authors: Gupta Krishna H. , Gaikwad Ajay K.
Published: April 2022

Due to technological development, gigantic skyscrapers and mega projects are possible resulting into increased demand of concrete for these projects. In municipal areas, site locations are in congested places where manual mixing is not possible. As Ready Mixed Concrete (RMC) is favoured more as it provides concrete of required quality and of required quantity. The success of RMC industry depends upon proper identification and assessment of risks or failure modes involved in various stages in concrete production. RMC industry is extremely complex in nature which contain many uncertainties resulting into complex risk management methodologies. The main aim of the research is to determine most critical risk that can occur at Ready Mix Concrete (RMC) plant and to provide suggestions to mitigate the most critical risk or failure modes. To achieve this aim, Failure Mode Effect Analysis (FMEA) is used combined with Analytical Network Process (ANP) to access and prioritize the risks involved at RMC plant as six risks resulted into same Risk Priority Number (RPN). Finally, it was concluded that injury at site is most critical risk involved at RMC plant. The research also provides suggestion to mitigate most critical risk.
Real-time Trajectory Planning and Vehicle Control for Automated Turning Traveling to the Specified Exit Point
Authors:   Osaka City University, JAPAN, Takiyama Takeshi ,   Osaka City University , Graduate school., JAPAN, Fujita Jinichi
Published: April 2022

Turning is necessary for a traveling vehicle when changing lanes or avoiding obstacles. Furthermore, indicating the trajectory or exit point of turning is obviously necessary for safety in autonomous driving. A mathematical restriction in the running area or a potential function was much reported for these purposes. However, the parameter setting of these methods is very complex. Furthermore, confirming the direction of the moving vehicle is necessary. Clothoid curve is a well-known trajectory to slacken the sudden change in curvature from straight direction to turning. It is also well known that the curve matches the vehicle turning trajectory when steering is performed at a constant speed. Therefore, the use of a clothoid curve is extensively reported for target-trajectory-generation. This process requires more time to obtain the turning trajectory, because these methods determine the clothoid parameters while examining the passing point. However, the real-time operation of an autonomous vehicle requires quick determination. Therefore, the present study investigates a new method for determining a turning trajectory
consisting of a clothoid curve using the turning exit conditions. First of all, a numerical analyses were carried out to obtain the relationship between the parameters of the unit clothoid curve and the end point coordinate position. Next, the relationship between the turning trajectory and the clothoid parameter were investigated using graphical features. Then, this paper showed a method to determine the clothoid parameter to travel to the specified exit point when automated turning. Also, this paper showed an algorithm to generate a lane-change trajectory by combining the clothoid curve. To apply for the automated traveling, a nonlinear control system was investigated to pass through the specified exit point. Also, a compensation method using a phase advancing transfer function were investigated to coincide well with the target trajectory because three variables were controlled by two inputs. This control system was examined using a radio controlled car. The experimental results showed well expected results and it showed that this method is effective and useful to pass through the specified exit point.

Public incentives play an important role in expanding the possibilities of using renewable energies, such as that generated from MSW (municipal solid waste) biomass, not only creating opportunities, but also several challenges. Thus, from the literature review, this paper aims to describe the feasibility (technical, economic, and environmental), potentialities, obstacles and readiness level of the technologies of energy generation from municipal solid waste. These technologies include the use of landfill gas, biogas generated by anaerobic digestion and direct burning of solid waste (incineration). Between the three technologies, landfill gas has greater economic viability, anaerobic digestion is classified as the most environmentally viable energy recovery technology, while incineration has the highest energy recovery potential. Regarding the readiness level of the technologies, incineration and anaerobic digestion are extensively used in Europe, United States and East Asia, while landfill gas is used extensively in the United States, Latin America and India. Moreover, the applicability of a technology should always have a set of factors into consideration (economic, environmental and technical), to be applied to local characteristics, in conjunction to other technologies.
Comparative Analysis of Concrete Water-Proofing Materials

Published: April 2022

Concrete is porous when exposed to water, because water passes through its pores defacing the concrete and corroding the reinforcements, this overall effect weakens concrete. Waterproofing of concrete is very essential in building parts which are constantly exposed to moisture from ground water and rain water. This study compared bituminous felt with cementitious crystalline waterproofing materials for concrete. In this study, a particular square area of concrete slab was assumed, and a market survey was conducted to determine the cost of purchase and installation of bituminous felt and cementitious crystalline waterproofing materials for the assumed square area. The bill of quantities for both options was done to aid the comparisons and cost of maintenance of both materials. The results of the study showed that bituminous felt was the most widely used waterproofing material, while cementitious crystalline waterproofing material on the other hand is not a very popular material as most building professionals did not know about its existence. The market survey showed that it was cheaper to install cementitious crystalline waterproofing material than to install bituminous felt and the cost of maintenance of cementitious waterproofing material was also negligible compared to bituminous felt. Though cementitious crystalline waterproofing material is new in Akure market, it has a promising future in the construction industry not only in Akure but in Nigeria’s construction industry at large.

Published: April 2022

A theoretical analysis of the stability of the non-equilibrium industrial processes is presented. A unified approach is proposed for the creation of the mathematical models of the processes that allows the determination of the rates at which the processes move to their thermodynamic equilibriums and their use for mathematical analysis of processes velocities stability. For this purpose is used mathematical stability theory, evolution (autonomous) equations, bifurcation theory (stable focuses, stable cycles), parameter eigenvalues and eigenfunctions.

The Zambezi River Basin system and wetlands in particular, have a high ecosystem services and economic value to large number to people the study aim was to assess the status of ecosystem services and their benefits in the wetlands of Barotse Flood plains (BFP). The study utilized both secondary and primary data sources. Primary data was collected using interview schedule, key informant’s interviews, Participatory rural appraisal and field observations. Simple random sampling was used to select proportional respondents from 9 district that are found study area. The wetland ecosystem services that were identified in BFP are: Provisioning which include water, fish, wild game, fruits, edible plants, reeds, sedge, pasture, thatching grass, sand and clay soil, and medicinal plants. Regulation; climate regulation (temperature and precipitation), ground water discharge and river flow regulation. Cultural; traditional ceremonies, sacred places and recreation. Support services; soil formation, alluvial and organic matter. The study found that the ecosystem services were affected by socio-ecological factors in the BFP that led to declining of ecosystem services in general. The Pearson coefficient correlation showed that there is a significant relationship of 0.930** at 0.01 level between socio-ecological factors and declined ecosystem services in BFP. The study recommended strategies such as the government, local leadership and other stakeholders to embark on protection and conservation of BFP since it is a recognized and designated Ramsar heritage site. Government also to embark on formulating new policies on ecosystem services management in the wetlands and to fully implement the already existing policies.
Blue Rubber Bleb Nevus Syndrome in a Pakistani Child: a case report and regional literature review
Authors: Habib Qaiser  , Kamran Sadiq  , Bushra Afroze
Published: April 2022

Blue rubber bleb nevus syndrome (BRBNS) is a rare disorder in which there is development of multiple venous malformations and haemangiomas in the skin and visceral organs. The lesions mostly involve the skin and gastrointestinal systems but other organs, including the liver, muscles, and the central nervous system, can also be involved. If untreated, affected individuals develop severe anaemia. Most cases are managed with iron supplementation and blood transfusions but some may require surgical resection, endoscopic sclerosis and laser photocoagulation. Here, we present a case of BRBNS in a four-year-old girl with multiple cutaneous lesions, melena and severe anaemia. Review of South Asian literature showed that only two cases (besides ours) have been reported from Pakistan and the rest were from India. This highlights the lack of awareness of BRBNS among physicians in Pakistan and the rest of South Asian countries.
