The purpose of the article is to provide theoretical and empirical evidence that narrative analysis in economics is not an integral part of qualitative research and is quite compatible with the methodology of quantitative research. The development of methods for collecting and processing data is one of the significant directions in the development of both empirical and theoretical research in economics. Of particular importance to this direction is the consistent expansion of the consideration of social factors in the study of decision-making processes, both at the micro and macro levels. Narrative economics, which has emerged and developed in the last decade, is an integral part of this trend. The article proposes and substantiates a methodology for empirical analysis of narratives considered as sources of quantitative information used in decision making. This distinguishes it from the methods of narrative analysis used in qualitative research in the social sciences, although they are not always distinguished in the literature. The technique combines the search for the frequency of occurrence of various phrases on the Internet with interview analysis, which significantly reduces the time and effort required to search and analyze the necessary information about social factors. The effectiveness of the proposed methodology is tested on the example of the analysis of narratives that characterize personal entrepreneurial networks, no statistical information about which is collected, although the networks themselves play an important role in the formation of new small businesses. The presented results of the analysis show that the technique makes it possible to obtain useful quantitative data on such objects of economic research.

Authors: Al-Jarf Reima 
Published: July 2023

This study aimed to explore whether educated Arabs prefer to read paper or digital materials and which reading technologies and applications they use. The sample consisted of 272 educated Arabs (81% males and 19% females) who are Twitter users, who gave 437 responses to questions, hashtags and threads asking, “which digital media and digital devices do you use for reading, why, the advantages and disadvantages of digital reading vs reading from paper material”. Data analysis showed that 71.5% of educated Arabs in the sample read traditional printed books and 28.5% read digitally and use digital reading technologies as follows: 15% listen to audiobooks, 6.5% use Kindle, and 7% use e-Ink, Audible, Storytel, Feedly, text-to-speech software (Read Aloud, Natural Reader Pro and Kurzweil 1000), Instapaper, Evernote, Raindrop, Pocket, Siri, eBooks, Artificial Intelligence (AI), Tarteel, Wajeez, Sibawayh Reader, and Screen Readers such as JAWS, Window Eyes, VoiceOver, Thunder, and HAL by blind students. Digital readers in this study use smart phones, iPads, tablets, and computer screens and are familiar with digital document formats such as Pdf, Epub, Mobi, IPA and AZW. The percentage of educated Arabs who use digital reading and reading technologies and apps is small, taking into consideration that many Arab people have access to the Internet and have a smart phone, a desktop or laptop computer and should be able to access a plethora of reading apps, digital resources, and reading technologies. It seems that many educated Arabs are not familiar with digital reading, eBooks, e-libraries, online reading resources, reading technologies and applications. Digital readers gave some explanations for their preferences and how they use digital media reading, when and where. Some recommendations for familiarizing children, students and the public with digital reading and reading technologies are given.

Approximate methods for analyzing semiparametric longitudinal models with nonignorable missing responses
Authors: Aloraini Najla , Sinha Sanjoy 
Published: July 2023

We often encounter missing data in longitudinal studies. When the missingness in longitudinal data is nonignorable, it is necessary to incorporate the missing data mechanism into the observed data likelihood function for a valid statistical inference. In this article, we propose and explore a novel semiparametric approach to estimating the regression parameters and variance components using a partially linear mixed model with nonignorable and nonmonotone missing responses. The ﬁnite sample properties of the proposed method are studied using Monte Carlo simulations, where our method is found to be very effective in capturing any curvilinear pattern in the mean response. The method is also illustrated using some actual longitudinal data obtained from a public health survey, referred to as the Health and Retirement Study (HRS).

Biochar for Improving crop Production in Nepal
Authors: Vista S P , Pandit N R 
Published: July 2023

Improving soil fertility and crop productivity is crucial to reduce food insecurity and poverty in Nepal. Biochar as a soil amendment has been found effective in increasing crop production. Here, we reviewed various biochar studies carried out in Nepal by different organizations and assessed future potential of biochar as an effective soil amendment. In this review, we have included the biochar pretreated (enriched) with nutrient or added separately in soil. We found that good quality biochar could be produced using the novel flame curtain metal and soil pit “Kontik” kiln with slow pyrolysis technology. Biochar produced from Kontiki found having high pH (9.8), organic carbon (OC, 72%), surface area (215 m2g-1) and cation exchange capacity (CEC, 72 cmol kg-1). Further, biochar application improved soil chemical properties (pH, OC, CEC, base cations) and nutrient availability such as available phosphorous (P) and potassium (K). Similarly, biochar addition increased crop yield significantly compared with non-biochar plots. Higher crop yield was achieved when biochar was enriched or charged with cattle urine. Thus, from this study, we suggest that biochar should be prioritized in government programs as a potential soil amendment and scale up or increase its use at farm level.

Published: July 2023

Four genotypes of quail Dhakai (D), White (W), Brown (Br) and Black (Bl) quail are being maintained at BLRI with the objectives of increasing the sixth-week body weight through selective breeding and selecting parental birds and breeding them in an assortative plan for the production of 8th generation birds. The parent males and females were maintained in cages for single-pair mating through selective breeding system for producing each generation. A total of 1118-day-old quail chicks comprising 4 types were hatched in one batch to produce eighth generation (G8). The expected genetic progress due to selection for 5th-week body weight was estimated for G8. The genotype had significant (p<0.001) effect on the body weight of quails at 5th week of age. The 5th-week body weight was 132.34±0.88, 123.91±0.52, 104.29±0.76 and 105.36±0.68g, respectively for D, W, Br, and Bl genotypes. The hatchability rate was significantly (p<0.001) higher in D (78.47%) compared to other three genotypes. The egg production percentage up to 24th week of age was 85.27±1.0, 80.22±1.61, 81.07±1.2 and 96.12±1.1, respectively for D, W, Br, and Bl and significantly (p<0.001) differed among all genotypes. Mortality percent among genotypes was statistically non-significant (p>0.05). Sixth-week body weight of males of D, W, Br, and Bl quails were expected to increase by 4.06, 6.36, 2.39, and 3.12g, respectively. While in females of D, W, Br, and Bl quails, the responses were 5.60, 3.61, 4.17, and 3.91g, respectively. Taken together, it may be concluded that Dhakai quail was superior for body weight and Black quail for egg production performance. These findings suggested continuing the quail breeding research for producing a suitable meat-type quail genotype in our country.

MAGNETOCALORIC EFFECT AROUND CURIE TEMPERATURE IN Ni50-x CuxMn38Sn12B3 SHAPE MEMORY RIBBONS
Authors: KIZILASLAN Olcay 
Published: July 2023

The
magnetocaloric effect in Ni50-xCuxMn38Sn12B3
ribbons depending on the Cu substitution (x= 0, 1, 3) was investigated around the
Curie temperature. The purpose of the present study was to analyze the
magnetocaloric effect around a second order phase transition (around the Curie
temperature) which has a smaller thermal hysteresis compared to a first order
phase transition (Martensitic transition). The Curie temperature of the ribbons
shifted to higher temperatures with increasing Cu content. A conventional magnetocaloric effect
(MCE) was observed around the Curie temperature when the ribbons are subjected
to a magnetic field change of 5 T. The magnetic entropy changes were
calculated based on the isothermal magnetization data using thermodynamic
Maxwell equation. The highest magnetic entropy change and the refrigerant
capacity
was
obtained for the x=1 ribbon.

magnetic resonance imaging is a technique with a primary and dominant effect in
the investigation of the cognitive functions of the brain since it has a
complex structure. In this study, data obtained from single subject was
examined. First statistical parametric mapping results were obtained after
applying the standard preprocessing steps with including smoothness. Spatial
smoothing was performed using a 3 mm Gaussian kernel which is twice of the
voxel size. Second, statistical parametric mapping results were obtained with
applying standard preprocessing steps without smoothing. The effects of these
two applications on the mapping results were compared for selected slices and
locations in terms of statistical and pattern.
A STUDY ON THE SEARCH POTENTIAL OF DOUBLY CHARGED LEPTONS AT THE SppC BASED ep COLLIDERS
Authors: OZANSOY Aysuhan , ALBAYRAK Oğuzhan 
Published: July 2023

We consider the single production of doubly charged leptons which take part in the extended weak isospin models and have exotic electric charges such as at the SppC based electron-proton (ep) colliders. We introduce the effective lagrangians describing the doubly charged lepton gauge interactions with SM leptons. We calculate the decay widths and production cross sections as a function of doubly charged lepton mass. We deal with the process and plot the kinematical distributions for the final state electron both for the signal and corresponding background. We perform a cut-based analysis to obtain the mass limits and couplings of doubly charged leptons at the SppC based ep colliders with the center-of-mass energies of TeV and TeV.

Authors: Rema Marninda Zahara  
Published: July 2023

Di alam liar burung bondol Jawa (Lonchura leucogastroides) dikenal sebagai hama bagi para petani karena seringnya memakan bulir dan biji padi yang sedang tumbuh di sawah. Pada kondisi burung bondol dipelihara di alam bebas hingga menjadi jinak, diprediksi perubahan jenis makanan yang dikonsumsi akan berpengaruh terhadap warna pada bulu-bulu yang tumbuh di bagian tubuhnya. Penelitian bertujuan untuk mengamati dan mendiskripsikan perubahan warna yang terjadi pada bulu-bulu burung bondol karena jenis makanan yang dikonsumsi berupa milet. Metode penelitian dilakukan secara kualitatif deskriptif. Hasil penelitian menunjukkan bahwa pemberian milet sebagai makanan burung bondol Jawa berdampak pada terjadinya perubahan warna bulu (melanisme) pada bagian perut menjadi hitam kecoklatan. Padahal, umumnya di bagian perut tersebut berwarna putih.

BackgroundToxoplasma gondii is an apicomplexan parasite that affects the health of humans and livestock, and an effective vaccine is urgently required. Nanoparticles can modulate and improve cellular and humoral immune responses.MethodsIn the current study, poly (D, L-lactic-co-glycolic acid) (PLGA) nanoparticles were used as a delivery system for the T. gondii dense granule antigens GRA12 and GRA7. BALB/c mice were injected with the vaccines and protective efficacy was evaluated.ResultsMice immunized with PLGA+GRA12 exhibited significantly higher IgG, and a noticeable predominance of IgG2a over IgG1 was also observed. There was a 1.5-fold higher level of lymphocyte proliferation in PLGA+GRA12-injected mice compared to Alum+GRA12-immunized mice. Higher levels of IFN-g and IL-10 and a lower level of IL-4 were detected, indicating that Th1 and Th2 immune responses were induced but the predominant response was Th1. There were no significant differences between Alum+GRA7-immunized and PLGA+GRA7-immunized groups. Immunization with these four vaccines resulted in significantly reduced parasite loads, but they were lowest in PLGA+GRA12-immunized mice. The survival times of mice immunized with PLGA+GRA12 were also significantly longer than those of mice in the other vaccinated groups.ConclusionThe current study indicated that T. gondii GRA12 recombinant protein encapsulated in PLGA nanoparticles is a promising vaccine against acute toxoplasmosis, but PLGA is almost useless for enhancing the immune response induced by T. gondii GRA7 recombinant protein.

Published: July 2023

BackgroundThe fertility of female kidney transplant recipients is increasing with the progression of transplant management. This article aims to evaluate the clinical prognosis of mothers and newborns for post-kidney transplant couples.MethodsFrom January 2019 to April 2022, a total of four couples, all kidney transplant recipients, were successfully prepared for pregnancy after a rigorous preconception evaluation, including three cases of natural conception and one case of in vitro fertilization. Data regarding the mother and newborn, including general clinical condition and laboratory results, were recorded and assessed throughout the pregnancy and up until 12 months after delivery.ResultsThe mean conception age of the mothers was 34.8 years (30–38 years), and the mean interval between renal transplantation and pregnancy was 6.6 years (3.7–8.7 years). All deliveries were by cesarean section and took place without incident. There were three premature births (&lt;37 weeks; average 35.1 weeks). In case 1 (in vitro fertilization), pre-eclampsia occurred during maternity, and this was the only case in which the fetal weight was less than 2,500 g (average 2,576.7 g). The mean Apgar score (1 min) was 7.8 (6–9) and reached 9 in all cases at 5 min. The mothers’ eGFR rose during mid-gestation, decreased in late pregnancy, and was largely restored along with proteinuria 1 year postpartum. Postnatal evaluation at 6 months showed normal neurological development. In addition, NK cell and IFN-γ levels increased and Treg cell and IL-10 levels decreased along with the onset of pre-eclampsia.ConclusionsPregnancies can succeed in couples who are both kidney transplant recipients. However, there might be higher risks of infertility, prematurity, and low birth weight.

Published: July 2023

Objectives: The goal of our bioinformatics study was to comprehensively analyze the association between the whole calpain family members and the progression and prognosis of hepatocellular carcinoma (HCC).Methods: The data were collected from The Cancer Genome Atlas (TCGA). The landscape of the gene expression, copy number variation (CNV), mutation, and DNA methylation of calpain members were analyzed. Clustering analysis was performed to stratify the calpain-related groups. The least absolute shrinkage and selection operator (LASSO)-based Cox model was used to select hub survival genes.Results: We found 14 out of 16 calpain members expressed differently between tumor and normal tissues of HCC. The clustering analyses revealed high- and low-risk calpain groups which had prognostic difference. We found the high-risk calpain group had higher B cell infiltration and higher expression of immune checkpoint genes HAVCR2, PDCD1, and TIGHT. The CMap analysis found that the histone deacetylase (HDAC) inhibitor trichostatin A and the PI3K-AKT-mTOR pathway inhibitors LY-294002 and wortmannin might have a therapeutic effect on the high-risk calpain group. The DEGs between calpain groups were identified. Subsequent univariate Cox analysis of each DEG and LASSO-based Cox model obtained a calpain-related prognostic signature. The risk score model of this signature showed good ability to predict the overall survival of HCC patients in TCGA datasets and external validation datasets from the Gene Expression Omnibus database and the International Cancer Genome Consortium database.Conclusion: We found that calpain family members were associated with the progression, prognosis, and drug response of HCC. Our results require further studies to confirm.
Effect of isolated intracranial hypertension on cerebral perfusion within the phase of primary disturbances after subarachnoid hemorrhage in rats

IntroductionElevated intracranial pressure (ICP) and blood components are the main trigger factors starting the complex pathophysiological cascade following subarachnoid hemorrhage (SAH). It is not clear whether they independently contribute to tissue damage or whether their impact cannot be differentiated from each other. We here aimed to establish a rat intracranial hypertension model that allows distinguishing the effects of these two factors and investigating the relationship between elevated ICP and hypoperfusion very early after SAH.MethodsBlood or four different types of fluids [gelofusine, silicone oil, artificial cerebrospinal fluid (aCSF), aCSF plus xanthan (CX)] were injected into the cisterna magna in anesthetized rats, respectively. Arterial blood pressure, ICP and cerebral blood flow (CBF) were continuously measured up to 6 h after injection. Enzyme-linked immunosorbent assays were performed to measure the pro-inflammatory cytokines interleukin 6 (IL-6) and tumor necrosis factor α (TNF-α) in brain cortex and peripheral blood.ResultsSilicone oil injection caused deaths of almost all animals. Compared to blood, gelofusine resulted in lower peak ICP and lower plateau phase. Artificial CSF reached a comparable ICP peak value but failed to reach the ICP plateau of blood injection. Injection of CX with comparable viscosity as blood reproduced the ICP course of the blood injection group. Compared with the CBF course after blood injection, CX induced a comparable early global ischemia within the first minutes which was followed by a prompt return to baseline level with no further hypoperfusion despite an equal ICP course. The inflammatory response within the tissue did not differ between blood or blood-substitute injection. The systemic inflammation was significantly more pronounced in the CX injection group compared with the other fluids including blood.DiscussionBy cisterna magna injection of blood substitution fluids, we established a subarachnoid space occupying rat model that exactly mimicked the course of ICP in the first 6 h following blood injection. Fluids lacking blood components did not induce the typical prolonged hypoperfusion occurring after blood-injection in this very early phase. Our study strongly suggests that blood components rather than elevated ICP play an important role for early hypoperfusion events in SAH.
