A Reflection of the Sun ( )
Authors: Harvey Sydney ,   Society for the Philosophic Study of the Contemporary Visual Arts
Published: August 2023

This paper explores a philosophical argument about the use of natural light in films. I argue that directors use sunlight as a visual metaphor to induce a sublime experience from the viewer to elevate the narrative. While it is more efficient in terms of time management and finances to use electric lights, sunlight creates a successful emotional effect on the viewer placing them in contemplation of the relationship between humanity, nature, and humility. Essentially, I am concerned with what it is that the capturing of sunlight accomplishes in these works of art that a light bulb can’t. In this paper, I consider how natural light is used to guide the viewer’s eye and how natural light makes us feel. I believe motion pictures are the perfect artistic medium to explore our emotional understanding of the sun as it not only captures objects in motion in the light of the sun it also captures the sun itself in motion. My intention is to provide a better understanding of the powerful psychological effect that the use of sunlight has on the viewer of a film.

Teaching Component Skills in Philosophy
Authors: Lee James ,   Philosophy Documentation Center
Published: August 2023

This paper will argue for the teaching of component skills in philosophy. We can distinguish between complex and component skills. Component skills bear a kind of constitutive relation to complex skills. We observe this distinction at use in standard pedagogies related to activities like sports, music performance, and mathematics. The central thesis is that devoting pedagogical resources to the development of component skills, especially at introductory levels, promotes better learning outcomes with respect to complex philosophical skills. Aside from defending this thesis, I will also provide a number of examples of activities that can be used to develop component skills.

Among the research that nowadays deals with the impact of digital technologies on attention, little is concerned with problematizing the theoretical premises about the nature of this cognitive faculty. Hence, even highly credited studies on digital distraction draw their conclusions from underexamined models of attention, despite them not being the only ones available. In our article we intend to focus on this problem, starting by discussing two case studies in the field of cognitive psychology and trying to show their theoretical shortcomings when compared with an alternative model of attention. We will thus explore the account that a contemporary phenomenologist, Paul Sven Arvidson, has provided of attention and distraction. Finally, we will try to question the conclusions of the empirical studies by reframing them within Arvidson’s model, suggesting the importance of sharpening the definition of attention and distraction as preliminary work for investigating how the digital relates to them.

Authors: Stone Sadie B. , Bisaccia Elizabeth , Zakhary Mary Soliman , Bashqoy Ferras , Wagner Deborah , Stoops Christine
Published: August 2023

Acute kidney injury (AKI) is a common complication among patients admitted to the neonatal intensive care unit. Nephrotoxic medications (NTMs) are known to increase the incidence of AKI, but the use of these ­medications is often unavoidable. Baby NINJA (Nephrotoxic Injury Negated by Just-in-Time Action) is a ­quality improvement (QI) project that may be implemented at individual institutions and aims to systematically identify AKI in neonates and infants receiving NTMs. The purpose of this review is to describe nephrotoxic AKI in the neonatal population, introduce the Baby NINJA QI project and its potential to reduce neonatal AKI, and outline strategies for effective implementation of Baby NINJA.

Authors: Pouransiri Zhara , Assadi Farahnak , Mohkam Masoumeh , Hooman Nakysa , Rostami Zahra , Mazaheri Mojgan , Azarfar Anoush , Sharbaf Fatemeh Ghane
Published: August 2023

OBJECTIVE

This systematic review and meta-analysis aimed to explore rituximab (RTX) associated infectious complications in children with glomerular disease.

METHODS

We performed an electronic search of PubMed, International Scientific Information (ISI), Scopus, and EMBASE between January 2010 and July 2021. Infection rates and total drug-related adverse events were the outcomes. Statistical heterogeneity was evaluated by using the I2 statistic. When there was statistical evidence of heterogeneity (I2 > 50%, p > 0.1), a random-effect model was adopted. Data analysis was performed with Stata17.0 software.

RESULTS

A total of 7 studies with 668 patients (136 with lupus nephritis [LN] and 532 with nephrotic syndrome were included in the meta-analysis. The pooled risk ratio showed that the administration of RTX was significantly associated with lower risk of infectious complications in patients with LN and nephrotic syndrome (0.72 [95% CI 0.58, 0.85]) when compared with population data of patients without glomerular disease (p = 0.2). There was no significant difference between the LN and nephrotic syndrome groups in terms of total serious adverse events or the occurrence of infections. There was significant heterogeneity among the reported studies (Q = 42.39, p < 0.001, I2 = 81%).

CONCLUSION

Administration of RTX in children with glomerular disease is associated with a lower rate of infections when compared with population data of patients without LN or nephrotic syndrome. Additional high-quality randomized controlled trials with long-term follow-up are needed to identify the long-term potential complications.

Authors: Wilson Genene Alexis , Bondi Deborah S. , Shah Pooja A. , Nelson Allison , Kumar Madan , Bhagat Palak H.
Published: August 2023

OBJECTIVE

This study evaluated newborn gentamicin serum concentrations after birth and the effects on the newborn after extended interval gentamicin dosing in peripartum mothers.

METHODS

This was a single-center, retrospective chart review of neonates born to mothers that received peripartum once-daily gentamicin dosing of approximately 5 mg/kg within 12 hours of delivery. A gentamicin serum concentration was obtained immediately after birth in the newborn. The primary outcome was initial neonatal gentamicin serum concentration after birth. Several secondary outcomes were evaluated including nephrotoxicity and ototoxicity. A subgroup analysis comparing baseline demographics of mother-newborn dyads with birth neonatal serum concentrations of less than 2 mcg/mL versus 2 mcg/mL or greater was performed.

RESULTS

A total of 32 mother-newborn dyads were included. Newborns had a median gestational age of 39.4 weeks and median birth weight of 3.4 kg. The mean initial gentamicin serum concentration was elevated at 3.1 ± 1.9 mcg/mL among all newborns. The median maternal dose based on actual body weight in newborns with gentamicin serum concentrations less than 2 mcg/mL was 3.5 (IQR, 3.3–4.8) mg/kg versus 4.8 (IQR, 4.3–5.2) mg/kg in those that had serum concentrations of 2 mcg/mL or greater (p = 0.025). All newborn gentamicin serum concentrations were less than 2 mcg/mL for maternal doses given less than 1 hour prior to delivery (n = 8). There were no significant differences in nephrotoxicity or ototoxicity.

CONCLUSIONS

Peripartum once daily dosing of gentamicin administered between 1 to 12 hours of birth may lead to clinically significant serum concentrations in newborns.

Authors: Gupta Neha , Ali Cherise , Talathi Saurabh
Published: August 2023

OBJECTIVES

This study aimed to evaluate the side effect profile of soybean oil lipid injectable emulsion ­(SO-ILE) and soybean oil, medium-chain triglyceride, olive oil, fish oil lipid injectable emulsion (SO,MCT,OO,FO-ILE) in critically ill children requiring parenteral nutrition (PN).

METHODS

This is an observational study of children admitted to our pediatric intensive care unit requiring PN for ≥7 days. Patients were divided into 2 cohorts: SO,MCT,OO,FO-ILE (n = 34) and SO-ILE (n = 111). Outcomes included development of hypertriglyceridemia (HTG), intestinal failure–associated liver disease (IFALD), length of stay, and mortality. Logistic regression was performed after controlling for duration and maximum dose of lipids.

RESULTS

The median maximum lipid dose was significantly higher in the SO,MCT,OO,FO-ILE cohort (2.7 vs 3 g/kg; p = 0.01). Prevalence of baseline HTG was similar in both cohorts. After excluding patients with baseline HTG, incidence of HTG upon PN introduction was higher in the SO-ILE cohort (51.2% vs 26.7%; p = 0.02). The SO-ILE cohort also had significantly higher triglyceride concentrations at peak and upon discontinuation of PN (p < 0.05). Direct bilirubin and C-reactive protein were significantly higher in the SO-ILE cohort after stopping PN. Five patients (3.4%) developed IFALD, 4 of whom were in the SO-ILE cohort (p = 0.85). Upon logistic regression, mortality rate and incidence of HTG remained significantly higher in the SO-ILE cohort (adjusted odds ratio, 2.3 [95% CI, 1.1–5.3]; p = 0.04; and adjusted odds ratio, 2.0 [95% CI, 1.3–5.1]; p = 0.03, respectively).

CONCLUSIONS

In critically ill children requiring PN, SO-ILE was associated with a higher risk of HTG, ­elevated direct bilirubin, inflammatory markers and mortality compared with SO,MCT,OO,FO-ILE.

Authors: Kenneally Allison M. , Leonhardt Kelsey R. , Schadler Aric , Garlitz Karen L.
Published: August 2023

OBJECTIVE

Review the efficacy and safety of an updated empiric vancomycin dosing protocol in a neonatal intensive care unit (NICU).

METHODS

Retrospective chart review including neonates with postmenstrual age (PMA) less than 40 weeks without renal dysfunction who received vancomycin per protocol at a single institution’s NICU before and after implementation of an updated dosing protocol. The primary outcome is the proportion of initial therapeutic troughs. Secondary outcomes include average trough, achievement of a therapeutic trough, number of days before attainment of a therapeutic trough, and proportion of acute kidney injury (AKI) during therapy.

RESULTS

The 2 groups were similar in gestational age, race, birth weight, PMA, and weight at time of vancomycin initiation. The post-implementation group had a higher proportion of initial therapeutic troughs (33.0% vs 55.1%) and a lower proportion of a subtherapeutic (58.7% vs 43.8%) and supratherapeutic (8.3% vs 1.1%) initial troughs (p = 0.002). The median trough was not different (9.20 vs 10.50 mg/L; p = 0.092). There was no difference in the proportions of achieving a therapeutic trough throughout therapy (69% vs 76%; p = 0.235); however, the post-implementation group achieved a therapeutic trough 1 day earlier (3 vs 2 days; p < 0.001). There was no difference in proportions of AKI developing between the pre-implementation vs post-implementation groups (10.1% vs 5.6%; p = 0.251).

CONCLUSIONS

Implementation of an updated vancomycin dosing protocol yielded a higher percentage of initial therapeutic vancomycin troughs and patients reached the therapeutic range 1 day earlier without increasing the proportion of AKI.

Authors: Patz Caroline , Liviskie Caren , Bird Merielle , Zeller Brandy , Vesoulis Zachary A. , Smyser Christopher D. , McPherson Christopher
Published: August 2023

OBJECTIVE

We describe a single center experience with gabapentin as adjunctive therapy in infants with neonatal opioid withdrawal syndrome (NOWS).

METHODS

We performed a retrospective chart review of infants receiving gabapentin for NOWS. Data points collected included patient’s sex, gestational age, maternal opioid exposure, NOWS medication dosing and length of therapy, number of failed wean attempts, time to successful morphine wean and duration of morphine wean, length of stay in the neonatal intensive care unit (NICU), and NOWS medications at discharge.

RESULTS

Six infants received gabapentin as adjunctive treatment for NOWS. All infants failed 2–4 morphine weans before initiation of gabapentin despite the addition of clonidine. All infants that received gabapentin were successfully weaned off morphine. The time to wean off morphine after gabapentin initiation varied from 4–35 days. Maximum gabapentin doses ranged from 15 – 42.7 mg/kg/day. Five infants were discharged from the NICU on gabapentin.

CONCLUSIONS

Gabapentin appeared to facilitate successful morphine weans in six patients with NOWS who were previously unable to wean despite the initiation of clonidine.
Allergic Reactions to Sugammadex: A Case Series and Review of the Literature
Authors: Banoub Rita , Alalade Emmanuel , Bryant Jason , Winch Peter , Tobias Joseph D.
Published: August 2023

Sugammadex is a novel agent for the reversal of neuromuscular blockade; it acts by encapsulating ­rocuronium or vecuronium, eliminating the active compound from the circulation, thereby providing rapid and complete recovery even with profound or complete neuromuscular blockade. Clinical advantages, including reduced incidence of residual blockade, decreased nausea and vomiting, decreased dry mouth, less change in heart rate, and reduced pulmonary complications, have been demonstrated when comparing sugammadex to conventional agents, such as neostigmine, that inhibit acetylcholinesterase. Although generally safe and effective, anaphylactoid and allergic reactions have been reported with sugammadex. The potential for hypersensitivity reactions with sugammadex and previous reports from the literature, as well as diagnostic and treatment strategies, are presented in 3 pediatric cases.

Exploring the Relationship between Social Media Marketing and Consumer Brand Switching Decision
Authors: Jaweria Ali  , Mohammad Shaiq
Published: August 2023

The current study emphasized the correlation between consumer decisions and social media marketing (SMM) regarding switching brands within a certain sector. As per the study, social media advertising is the most important factor for firms to raise brand recognition. Businesses may efficiently encourage their items on online platforms while grabbing consumers' attention. To perform the study effectively, the author, in this case, included previous research in the literature review. The significance of brand switching, engagement, electronic word of mouth (e-WOM), and advertising is addressed in this study as it relates to SMM and customer-based brand-switching decisions. Online or social media platforms now play a critical role in determining customer views and preferences, giving businesses previously unheard-of chances to interact with their target market. The study sheds light on how these social media interactions impact customer brand loyalty and brand-switching decisions. The study, based on quantitative analysis of consumer and engagement metrics from social media to meet our goals, offers a more inclusive knowledge of the overall link amid the factors that were found. Findings show a favourable correlation between the activity of social media and loyalty to the brand among consumers. Social media users that interact with a brand more regularly have higher brand loyalty, lowering the likelihood of transferring brands. e-WOM also significantly impacts how people choose which brands to buy. Brand loyalty is considerably increased by positive e-WOM spread via social media platforms, and the chance of brand switching is decreased. Additionally, the study explores how different advertising formats and strategies alter consumer perceptions, which has influenced their brand loyalty and switching behaviour over the years. This is done on the topic of brand switching by customers. In conclusion, the current study offers important new perspectives on how social media marketing is developing and how it affects brand choice.

Relationship of platelet subgroups with prognosis and mortality in patients with mild, severe and critical COVID-19
Authors: ERGENÇ Zeynep , KAYA Gülsüm , KARACA OCAK Özlem , İNCE Özgür , GÜNAY Serkan , ERGENÇ Hasan
Published: August 2023

Introduction: This study investigates whether platelet-related indicators including platelet count (PLT), mean platelet volume (MPV), platelet distribution width (PDW), Plateletcrit (PCT), and platelet large cell ratio (P-LCR) could be effective biomarkers in the prognostic of 2019-novel coronavirus disease (COVID-19) fatality.

Methods: Out of 380 patients diagnosed with COVID-19, 98 patients were randomly and retrospectively were included in our study. Detection of COVID-19 was performed according to the World Health Organization (WHO) guidelines and using quantitative polymer chain reaction (qPCR). Clinical and laboratory data and medical records for all study participants were collected from a digital version of their health history at Ayancik State Hospital and Diyarbakır Gazi Yaşargil Training and Research Hospital. All patients were followed up daily until discharge or death and were eventually classified into three categories: Mild, severe, and critical patients. Data analysis was performed using SPSS-26 for Windows (Statistical Package for Social Science, SPSS Inc. Chicago IL, USA®Z), and a 95% confidence level was selected. P < 0.5 was considered statistically significant.

Results: Of participants, 64.3% of the patients are 65 years and older, 54.1% are male, 60.2% survived, 39.8 % died and 35.7% are in critical condition. The mortality rate is higher in males and 65 years and older. While PLT (190,24) and PCT (0,21) measurements were higher in surviving patients, MPV (10,67), PDW (16,15) and P-LCR (30,82) measurements were higher in deceased patients. PDW and PCT measurements are more effective in predicting mortality state according to Roc analysis. The measurement that best predicts the deceased status of patients who are positive according to the cut-off value determined is PDW (0.621), and the measurement that best estimates the surviving patients is PLT (0.925).

Conclusions: In our study, it was concluded that high MPV, PDW and P-LCR and low platelet values are associated with poor prognosis of COVID-19 disease, and PDW and PCT measurements are more effective in predicting mortality in patients with COVID-19 infection. Laboratory parameters such as MPV, PDW, P-LCR, PDW, and PCT can provide clinicians with predictions of prognosis and mortality from COVID-19 disease.
Existence results for nonlinear Schrodinger equations involving the fractional (p,q)-Laplacian and critical nonlinearities
Authors: Lv Huilin , Zheng Shenzhou , Feng Zhaosheng
Published: August 2023

In this article, we consider the existence of ground state positive solutions for nonlinear Schrodinger equations of the fractional (p,q)-Laplacian with Rabinowitz potentials defined in \(R^n\),  $$ ( -\Delta ) _p^{s_1}u+( -\Delta )_q^{s_2}u+V( \epsilon x) ( | u|^{p-2}u+| u| ^{q-2}u) =\lambda f( u) +\sigma | u| ^{q_{s_2}^{\ast }-2}u. $$ We prove existence by confining different ranges of the parameter \(\lambda\) under the subcritical or critical nonlinearities caused by \(\sigma=0\) or 1, respectively. In particular, a delicate calculation for the critical growth is provided so as to avoid the failure of a global Palais-Smale condition for the energy functional.

Global well-posedness for Klein-Gordon-Hartree and fractional Hartree equations on modulation spaces
Authors: Bhimani Divyang G.
Published: August 2023

We study the Cauchy problems for the Klein-Gordon (HNLKG), wave (HNLW), and Schrodinger (HNLS) equations with cubic convolution (of Hartree type) nonlinearity. Some global well-posedness and scattering are obtained for the (HNLKG) and (HNLS) with small Cauchy data in some modulation spaces. Global well-posedness for  fractional Schrodinger (fNLSH) equation with Hartree type nonlinearity is obtained with Cauchy data in some modulation spaces. Local well-posedness for (HNLW), (fHNLS) and (HNLKG) with rough data in modulation spaces is shown. As a consequence, we get local and global well-posedness and scattering in larger than usual \(L^p\)-Sobolev spaces.

Solutions and eigenvalues of Laplace's equation on bounded open sets
Authors: Yang Guangchong , Lan Kunquan
Published: August 2023

We obtain solutions for Laplace's and Poisson's equations on bounded open subsets of \(R^n\) (\(n\geq 2)\),  via Hammerstein integral operators involving kernels and Green's functions, respectively. The new solutions are different from the previous ones obtained by the well-known Newtonian potential kernel and the Newtonian potential operator. Our results on eigenvalue problems of Laplace's equationare different from the previous results that use the Newtonian potential operator and require \(n\geq 3\). As a special case of the eigenvalue problems, we provide a result under an easily verifiable condition on the weight function when \(n\geq 3\). This result cannot be obtained by using the Newtonian potential operator.

Coupled porosity-fluid concentration flux-temperature waves in isotropic porous media
Authors: Fama Alessio , Restuccia Liliana
Published: August 2023

In this article, we study a problem on propagation of coupled porosity,  fluid concentration flux, and temperature waves. We use a model formulated in previous papers for porous media saturated by a fluid flow, in the framework of non-equilibrium thermodynamics. We derive three modes of propagation in the one-dimensional and perfect isotropic case, and then we test the validity of the model. The waves propagation velocities are represented in diagrams as functions of the wave number. The derived results have applications in technological sectors  such as seismology, medical sciences, geology and nanotechnology.

We investigate a logarithmically improved regularity criteria in terms of the velocity, for the vorticity, for the Navier-Stokes equations in homogeneous Besov spaces. More precisely, we prove that if the weak solution u satisfies either $$\displaylines{ \int^T_0 \frac{\|u(t)\|^{\frac{2}{1-\alpha}}_{{\rm \dot{B}^{-\alpha}_{\infty, \infty}}}} {1+\log^+\|u(t)\|_{\dot{H}^{s_0}}} \, dt <\infty, \quad \text{or}\quad \int^T_0 \frac{\|w(t)\|_{\dot{B}^{-\alpha}_{\infty, \infty}}^\frac{2}{2-\alpha} } {1 + \log^ + \|w(t)\|_{\dot{H}^{s_0}}}\,dt<\infty\,, }$$ where w =rot u, then u is regular on (0,T].Our conclusions improve some results by Fan et al. [5].

Asymptotic behavior of solutions to porous medium equations with boundary degeneracy
Authors: Hao Xutong , Zhou Mingjun , Jing Xinxin
Published: August 2023

This article concerns the asymptotic behavior of solutions to a class of one-dimensional porous medium equations with boundary degeneracy on bounded and unbounded intervals. It is proved that the degree of degeneracy, the exponents of the nonlinear diffusion, and the nonlinear source affect the asymptotic behavior of solutions. It is shown that on a bounded interval, the problem admits both nontrivial global and blowing-up solutions if the degeneracy is not strong; while any nontrivial solution must blow up if the degeneracy is strong enough. For the problem on an unbounded interval, the blowing-up theorems of Fujita type  are established. The critical Fujita exponent is finite if the degeneracy is not strong, while infinite if the degeneracy is strong enough. Furthermore, the critical case is proved to be the blowing-up case if it is finite.

OPTIMIZATION OF CRUSHED GLASS WASTE AS A PARTIAL REPLACEMENT FOR FINE AGGREGATE FOR ENVIRONMENTAL SUSTAINABILITY
Authors: Mahmoud H. A. , Abba H. A. , Ahmad Z. B.
Published: August 2023

Recent years have witnessed a rise in the quantity of waste glass due to a rise in industrialization and a rapid improvement in living standards, which can lead to the depletion of natural resources and pollution of the environment. The potential use of waste recycled glass as sand replacement in concrete was examined, response surface methodology (RSM) was applied to optimize process parameters. A randomized custom design was employed to determine the effect of glass-sand (G-S) replacement parameters on the developed concrete compressive strength. The regression analysis revealed an excellent fit between the experimental data and the model, as measured by the coefficient of determination (R
2) of 0.9094, Adjusted R
2 of 0.8591 and a model F-value of 18.07. The optimum percentage combination was 10% of glass with 90% of sand, as recorded from the desirability function. At the optimal combination, the compressive strength of concrete was 30.5 MPa. The experimental findings ascertain that the substitution of sand with glass aggregate can be a suitable alternative to natural sand and can effectively be applied industrially. The local waste glass materials have demonstrated that they can effectively substitute for a portion of traditional materials and mitigate the environmental pollution associated with solid waste disposal.

Published: August 2023

Demand for mortgage finance showed a slowdown. And also, property residential sales showed a slowdown. As is well known, most consumers buy property residential is financed by mortgage finance. Through LTV policy, the Bank of Indonesia wants to stimulate demand for mortgage finance and also property residential sales to could boost economic growth sustainably. A question is whether changes in the LTV ratio could boost economic growth sustainably and whether other factors are affecting demand for mortgage finance. This article sees the question by considering what the impacts are in both lower-middle-income and higher-middle-income provinces. By regressing the statistical model Fixed Effect Model (FEM) and Random Effect Model (REM), the result shows that LTV policy is affecting positively the demand for mortgage finance, particularly in lower-middle-income provinces. When the LTV ratio increased, the demand for mortgage finance in lower-middle-income provinces is higher than the demand for mortgage finance in higher-middle-income provinces. Moreover, mortgage finance reflects normal goods for higher-middle-income provinces while reflecting inferior goods for lower-middle-income provinces. On the other hand, higher mortgage interest lowers the demand for mortgage finance, particularly in lower-middle-income provinces.

The aim of the study was to analyze sociodemographic factors associated with oral health-related quality of life among elderly population.  Methods: a cross-sectional study was undertaken in 20-23 February 2022 with 75 elderly people aged 60 years and older. This sample size was representative of the geriatric population living at home in the RW 02, Kelurahan Sukahati, Kecamatan Cibinong, Kabupaten Bogor. Participants were interviewed at home by trained interviewers using a 15-item questionnaire that included socio-demographic indicators (gender and age). Participants' OHRQoL were evaluated using a validated Indonesian version of GOHAI. The questionnaire consisted of 12 questions, with answers ranging from 1 to 5. GOHAI evaluates three aspects: (A) Physical functions such as speaking, eating and swallowing. (B) Dissatisfaction with appearance and psychosocial effects, including contact with others, self-esteem for oral health, and concerns about appearance. (C) Pain or discomfort, including taking medication to relieve pain. Results: a total of 75 participants completed the questionnaire. Most of the participants were between 60-69 years old (52%). The study population included 33 men (44%) and 42 women (56%). Most of the participants reported a poor OHRQoL score (GOHAI ? 56).  There was significantly associated between age and gender with GOHAI category (p = 0.026, CI 95%; p = 0.000, CI 95%). Conclusion: most of respondents reported a poor oral health related quality of life. Sociodemographic factors (age and gender) associated with oral health related quality of life in elderly people.
Determination of the content of heavy metals in residues released from manufacturing procceses of Ni-Cd batteries by atomic absorption spectrometry
Authors: Aliu Milihate
Published: August 2023

The residues discharged from industry contain a bulk amount of liquid and solid wastes with substantial quantities of toxic heavy metals. These wastes from the industries is not only polluting the water but also the sediment in the adjunct river and ultimately affecting the aquatic life. The objectiv of this study is to evaluate the heavy metal (i.e., Cd, Cu, Co, Fe, Pb, Mn, Ni and Zn) concentration in solid residue samples released from the manufacturing processes of Ni- Cd batteries. For this purpose samples were digested with aqua regia and analysed for metals by the atomic absorption spectrophotometer (AAS). This study revealed that the metal concentration for Cd, Cu, Co, Fe, Pb, Mn, Ni and Zn were found to be 4200-16500 mg/kg, 140-850 mg/kg, 100-629 mg/kg, 170-630 mg/kg, 150 -920 mg/kg, 30-250 mg/kg, 6400-35000 mg/kg and 110-800 mg/kg respectively. The concentration of heavy metals in residues samples decreased with the following order: Ni > Cd > Pb > Cu > Zn > Co > Fe > Mn. The results of this study provide support for the prevention of human health risks and the control of soil heavy metal pollution. In the industrial area, waste management is one of the difficult and most challenging issue. Sustainable solution is the best fit for dealing with the waste management,  because when discharged on the land as well as dumped into the surface water, which ultimately lead to contamination due to accumulation of toxic metals and resultes in a series of problems in living beings, because they cannot be completely degraded.

Mark Twain on Reproducibility, more or less
Authors: Katz Daniel S.
Published: August 2023

(This is taken in part from another blog post.  Doug Thain asked a few of us to participate in a group blog on reproducibility, and this was my initial post on that blog.) Given my two roles, a researcher and a funder, it’s clear to me that reproducibility in science is increasingly seen as a concern, at least a high level. And thus, making science more reproducible is a challenge that many people want to solve.

I updated Citation.js to accept quickscrape's results.json. Results can be viewed here. I made a card prototype for the database HTML page, using data extracted with quickscrape. It's mainly, although not advanced, a design thing, but it's nice to see what information I can fit. Results are here. With opened paper Without opened paper I have taken a look at quickscrape. What I'd like to do is to practise building a similar program myself, first just outputting strings to the command line, later processing arguments, to eventually use in my project.
Characterizing the species-abundance distribution with only information on richness and total abundance [Research Summary]
Authors: White Ethan
Published: August 2023

 This is the first of a new category of posts here at Jabberwocky Ecology called Research Summaries. We like the idea of communicating our research more broadly than to the small number of folks who have the time, energy, and interest to read through entire papers. So, for every paper that we publish we will (hopefully) also do a blog post communicating the basic idea in a manner targeted towards a more general audience.
