Plant breeders performed multi-trait selection using a suitable method, one of which is selection index. A multivariate analysis may be used for developing a selection index model. The objective of this experiment was to select doubled haploid rice lines with high yield potential and good agronomic characters based on the selection index. The experiment was carried out using a single factor completely randomized design with three replications, from August 2018 to December 2019. The study included 89 doubled haploid (DH) lines derived from anther culture as well as four check varieties (Ciherang, Inpari 30 Ciherang Sub1, Inpari 41, and Inpari 35 Agritan). Development of selection index model considered the results of analysis of variance, correlation analysis, path analysis, principal component analysis, and aimed plant ideotype. The findings revealed that there was variation in agronomic traits and yield among the DH lines tested. The selection index model can be formulated as I (index value) = 3*0.75 yield + 0.85 total grain per panicle – 0.85 plant height. Based on this model, 85 lines had index value and yield higher than Inpari 41. The selected DH lines were included in the subsequent field evaluation.

Authors: Sheet Waleed M. 
Published: July 2022

This research concerning with the effect of using the effective microorganisms on the efficiency of extended Aeration Activated Sludge Units which consist from many strain of Bacteria, Fungi and Actinomycetes in addition to board spectrum of nutrient and elements which important to growth, The use of this product is practically applied by using two bench scale laboratory units where they are operated to treat the wastewater after completing and preparing the activated sludge units to work under the same conditions of temperature and detention time (DT).
One bench scale is fed with wastewater and the other is operated by using a mixture of EM-1 along with the wastewater. It is noticed that the use of EM-1 with wastewater has reduced the smell resulting from disintegration in the aeration basin. Further, the color of sludge in the unit where EM-1 is added is light brown which means more activity and vitality. Besides, the concentration of mixed liquor volatile suspended solids (MLVSS) is increased by using EM-1 by 30% due to the increase of nutrients and a reduction in the sludge volume index (SVI) which is an important factor in the performance of the secondary settling basins which means a reduction in bulking of sludge, which is considered one of the most notable operating problem in activated sludge units. As a result bulking of sludge reduced by25% when EM-1 is used. Thus, EM-1 has participated in solving three important operating problems suffered by operators of these treatment units easily and without using complicated technologies or appliances. Further, EM-1 improves the removal efficiency of the units about 6-8% due to the reduction in chemical oxygen demand in the treated wastewater leaving the unit by 32%.

Published: July 2022

Thermal insulation properties of a blend mixture composed of different percentages (50% ,60% ,70% and 80%) of styropor with concrete and sand of equal volumetric percentages 15%, 20%, 25%,and 10% respectively. This study includes calibration of instruments for measuring the heat transferred through samples and investigating the way that used for calculating the proportions of mixing for each sample.
Finally the experiments were conducted in order to determine the correlation of thermal conductivity of each sample with its mean temperature. It was demonstrated that the new mixture has good rank of thermal properties among the other insulators, with thermal conductivity of 0.3 w/m.oC. This value is lower than the mean value of thermal conductivity values of concrete insulators in the buildings. Experiments are carried out under a temperature range of (14- 70) oC and under different volumetric proportions of the mixture.
The experimental results showed that the behavior of the thermal conductivity with the mean temperature on the two faces of the sample is directly proportional like the other insulators.

Published: July 2022

Background:An elevated cardiovascular risk has been demonstrated in middle-aged individuals with onset of hair greying before the age of 30 years. Increased serum levels of pro-inflammatory cytokines, interleukin-6 (IL-6) and tumour necrosis factor-alpha (TNF-α), indicate an ongoing state of chronic inflammation that is correlated with cardiovascular risk but have not been studied earlier in patients with early onset of hair greying.Aim/Objective:To study various cardiovascular risk markers including pro-inflammatory cytokines interleukin-6 (IL-6) and tumour necrosis factor-alpha (TNF-α) in patients with premature canities.Methods:This was a hospital-based case-control study of 40 patients with premature canities (age between 19 and 25 years; >5 grey hair) and an equal number of age and gender-matched healthy controls. The blood pressure, pulse rate and body mass index were recorded, and investigations including fasting blood sugar, serum insulin, fasting lipid profile, high sensitivity c-reactive protein (hs-CRP), IL-6 and TNF-α were performed. The homeostatic model assessment of insulin resistance (HOMA-IR) was calculated for all the participants.Results:The mean blood pressure, fasting blood sugar, serum insulin, hs-CRP and HOMA-IR were all significantly elevated in patients with premature canities and the serum HDL levels were significantly lower. A greater number of patients with premature canities had significantly elevated IL-6 as compared with the controls.Limitations:The sample size was small. A subjective scale was used for grading the severity of premature canities. Trichoscopic evaluation of severity of greying or modified phototrichogram could not be used in this study.Conclusion:Abnormalities in cardiovascular risk markers were found in patients with premature canities. Screening and counselling of patients with premature greying of hair is recommended in order to prevent future cardiovascular disease.

Published: July 2022

Este artigo contempla parte das reflexões realizadas a partir de uma pesquisa de doutorado em educação desenvolvida em dois quilombos e em duas salas de Educação Infantil públicas no estado de Santa Catarina, para o que foi selecionado um grupo de sete crianças quilombolas (três meninas e quatro meninos) com idades situadas entre quatro e seis anos de idade como sujeitos principais da pesquisa. A motivação central da investigação foi compreender e analisar, fundamentada em um estudo etnográfico, as relações educativas que as crianças quilombolas estabelecem entre si, com os adultos e com outras crianças no espaço institucionalizado da educação infantil e no espaço da comunidade quilombola onde moram. A base teórica direcionou-se para uma interlocução entre os campos da Pedagogia, Sociologia da Infância e Antropologia da Criança. A pesquisa evidencia que as crianças quilombolas sofrem constrangimentos na relação com as demais crianças e que os professores têm dificuldade de lidar com as diferenças culturais no espaço institucionalizado. Por fim, a pesquisa evidencia um alto grau de cumplicidade, autonomia e criação entre as crianças nos quilombos pesquisados e demostra que suas formas de expressão ou de sociabilidade podem suscitar outras maneiras de pensar a educação institucionalizada.

Pemodelan Opsi Saham Karyawan Menggunakan Pendekatan Top-Down
Authors: Megawati Megawati , Artiono Rudianto 
Published: July 2022

Abstrak
Opsi saham merupakan suatu perjanjian yang memungkinkan pemiliknya untuk melakukan call (menjual) atau put (membeli) suatu saham dengan harga yang telah ditentukan pada waktu tertentu. Salah satu jenis opsi saham adalah opsi saham karyawan (OSK) atau yang lebih dikenal dengan Employee Stock Options (ESO). Pemegang OSK dapat melakukan exercise opsi lebih awal setelah melewati vesting period dan secara bertahap melakukan exercise terhadap opsi yang tersisa sebelum maturity time. Penelitian ini bertujuan untuk memodelkan harga opsi saham karyawan melalui suatu analisis fundamental yakni analisis yang mempelajari hal-hal yang berhubungan dengan kondisi keuangan atau perusahaan dan umumnya digunakan untuk menentukan saham yang ingin dijual atau dibeli dengan menggunakan pendekatan top-down. Pendekatan ini diperlukan oleh perusahaan yang memiliki saling ketergantungan antar unit operasi dalam rangka meningkatkan koordinasi antara manager dan karyawan. Perspektif perusahaan untuk menentukan harga OSK umumnya melibatkan banyak opsi dengan jangka waktu lama. Untuk menghitung harga OSK, disajikan dua metode numerik yaitu transformasi fast fourier dilanjutkan dengan metode beda hingga untuk memecahkan sistem persamaan diferensial parsial terkait dengan opsi vested dan unvested. Metode numerik yang diusulkan tidak hanya berlaku untuk pengeluaran harga OSK, tetapi juga berguna untuk memahami efek gabungan dari intensitas exercise dan risiko pemutusan hubungan kerja pada penentuan harga OSK.

Abstract
A stock option is an agreement that allows the owner to call (sell) or put (buy) a stock at a predetermined price at a certain time. One type of stock options is employee stock options (OSK) or better known as Employee Stock Options (ESO). OSK holders can exercise options earlier after the vesting period and gradually exercise the remaining options before maturity. This study aims to model the price of employee stock options through a fundamental analysis, namely an analysis that studies matters relating to the financial condition of the company and is generally used to determine which shares to sell or buy using a top-down approach. This approach is needed by companies that have interdependence between operating units in order to improve coordination between managers and employees. The company's perspective for pricing OSK generally involves many long-term options. To calculate the OSK price, two numerical methods are presented, namely the fast Fourier transformation followed by the finite difference method to solve the system of partial differential equations related to vested and unvested options. The proposed numerical method is not only applicable to OSK pricing, but is also useful for understanding the combined effect of exercise intensity and risk of termination of employment on OSK pricing.
