Published: July 2019

Abstract
The length-weight relationship, condition factor, fecundity, gonadosomatic and hepatosomatic indices of Parachanna obscura from the Anambra River were determined between December 2015 and June 2016. Eighty-three live samples of P. obscura were obtained from fishermen. Descriptive statistics, correlation and regression analysis were used to analyze the obtained data. The length-weight relationship had R values of 0.933, 0.843 and 0.896 for male, female and combined sexes, respectively. The b value of 3.133 for male and 2.674 for female were not significantly different (P>0.05). Mean condition factors of 0.89±0.33 and 0.80±0.21 were obtained for female and male, respectively. The largest number of eggs (10,965) was found in a female with the body weight of 154 g, gonad weight of 9.1 g and egg size of 1.3 mm, while the least fecund female with 1820 eggs weighed (94 g) and had a gonad weight 2.1 g with egg size of 1.0 mm. The hepatosomatic indices ranged between 0.55±0.20 and 0.64±0.29 in both male and female, respectively, while female gonadosomatic index average was 2.05±1.44. There was a positive correlation between fecundity and gonad weight.

Published: July 2019

Abstract

Objective: The article’s purpose is twofold: 1) to demonstrate how a corporate culture influences an enterprise’s success, and 2) how important it is to follow its values throughout the business down to each individual employee.

Methodology: The study shows how the structure of a business and its success are affected by being family-owned company. The paper is based on expert individual semi-structured in-depth interviews with selected board members as well as the Chief Operating Officer (COO) of a foreign subsidiary.

Findings: The findings illustrate how the guidelines set up by the mother company affect daily activities. Furthermore, the results indicate how the company’s objectives are accompanied by the defined corporate values, and how they are transferred to the management team and each employee.

Value Added: The study, which is rather of a practical nature, proposes some management rules applying to the daily work of the Board, the COOs and the units abroad. This policy gives an insight how the family enterprise communicates its values and beliefs in order to maintain definite working practices around the world.

Recommendations: The paper gives an insight into the international market challenges for family-owned businesses, using August Storck KG as an example. In any firm, corporate culture should be built on stable and timeless values repetitively displayed, reflected in all activities and internalized by the entire team. The key is the need to connect the company’s goals with the values resulting from being a family business. Consequently, employees have a great interest in a positive development of the firm and hence give their best working expertise to ensure it.

Abstract
Companies aspire to fulfil consumers’ needs, wants and desires by offering products and services. Due to globalization and digitization, the world became a small village by facilitating the obtainability of products/services across the globe. Furthermore, the online purchasing via social platforms mirrors the traditional purchasing process. Gamification, game techniques and elements have been employed in the different domain for engaging and motivating consumers, students, end-users in numerous countries and cultures. Gamification is considered the appliance of game techniques and game elements in the non-game environment. It’s been adjusted in different models founded as a need to explore and explain variables, phenomena and theories. Game mechanics as one of the game elements are applied in different disciplines to achieve better performance, fruitful collaboration, active and enthusiastic participation, creating enjoyable, pleasurable and entertaining environment. Aesthetics are described as the sensory part that game evoke within the player. To identify the differences within consumers who purchase via social media when game mechanics and aesthetics are applied, the chi-square test for independence has been employed. The results estimate that the association between products and services as variables is not statistically significant and the relationship between them is weak or moderated. The findings of this research are useful for private companies and other interested stakeholders.

Published: July 2019

Abstract
Vegetable oil based fuels significantly enable reducing the costs of fuel purchased. CI engine vehicles with rotary and inline injection pump can be fuelled by vegetable oil based fuels instead of being fuelled by diesel. This is very common, since their price is lower in comparison with diesel. The article focuses on the impact of using fuels made from vegetable oil on selected vehicle characteristics in particular conditions. It includes the measurements of the impact of using fuels such as FAME, fresh oil and used oil on the engine smoke opacity, content of selected emissions in the exhaust gases as well as on the engine power and torque’s course. The measurement results are mutually compared with the results measured when using diesel. In order to secure the measurements to be repeatable, they were performed in laboratory at the cylinder test station MAHA MSR 1050. The vehicle tested during its last 100,000 kilometres driven by vegetable oil based fuel has been selected for these measurements. Therefore, by these measurements, it was also possible to assume partially the impact of long-term using aforesaid fuels on selected vehicle characteristics.

Authors: Kang Hee Wan 
Published: July 2019

Twenty primers of 20 mer referred to universal rice primer (URP) were developed from a repetitive sequence of rice genome. URP-PCR protocol employed stringent PCR with high annealing temperature throughout the thermo-cycling reaction, giving high reproducibility. Under the PCR condition, each single URP primer produced characteristic fingerprints from diverse genomes of bacterial species. The universal application of URP-PCR was demonstrated by applying it to 24 strains from Pectobacterium carotovoum subsp. carotovorum, 41 Agrobacterium vitis strains, 3 Xanthomonas spp. 5 Pseudomonas spp, Rhizobium sp. plant pathogenic bacteria, human and animal pathogenic bacterial strains including 6 Escherichia coli, 4 Salmonella spp., 7 Mycobacterium spp and 3 Blucella abortus strains. In addition, thermophilic bacteria were randomly isolated form high temperature compost and their URP-PCR polymorphisms were characterized with genetic relatedness. PCR approach using URP primers will be useful for studying DNA diversity of diverse prokaryotic genomes, especially at inter- and intra species levels.

Identifikasi forensik dengan pemeriksaan DNA yang dapat digunakan untuk menentukan asal usul anak; kasus paternitas; hubungan kekeluargaan; maupun identifikasi korban tak dikenal, semakin hari semakin diakui keberadaannya dalam menunjang penegakan hukum di tanah air. Hanya saja dalam perkembangannya pemeriksaan dengan menggunakan bahan DNA ini bukannya tanpa persoalan. Salah satu persoalan yang seringkali menjadi masalah yang serius bagi ahli DNA forensik maupun ahli DNA lainnya adalah kondisi DNA yang tergedradasi atau yang dikenal dengan istilah degraded DNA. Salah satu alternatif yang ditempuh dalam degradasi DNA saat ini oleh ahli DNA forensik adalah melalui penggunaan mini primer set, yakni melalui metode pengurangan ukuran STR assays, pada pemeriksaan lokus DNA inti. Penelitian ini menggunakan mini primer CSF1PO, FGA & D21S11 pada bahan gigi molar dengan perlakuan paparan 5000C dalam waktu 20 dan 30 menit serta suhu 7500C dalam waktu 20 dan 30 menit.
Hasil yang didapatkan terjadi penurunan kadar DNA gigi yang bermankna (p<0.05) sebagai efek paparan suhu tinggi. Visualisasi hasil PCR didapatkan hanya lokus CSF1PO yang masih terdeteksi dengan mini primer pada paparan suhu 7500C selama 30 menit (paparan maksimal penelitian ini) sehingga melalui lokus tersebut sangat potensial dalam pemeriksaan identifikasi melalui analisis DNA terutama dalam kondisi terdegradasi efek paparan suhu tinggi, serta mempercepat proses identifikasi terutama pada kejadian bencana (mass disaster) maupun kasus-kasus kriminal lainnya.

A Research of the utilization of spectrum shift in confirmation test for barbiturate using TLC-Spectrophotodensitometry has been done. Analyte was analyzed using two mobile phases, that are TD (chloroform: acetone = 80 : 20) and TE (ethyl acetate: methanol: ammonia = 85 : 15 : 5) with Al-TLC Silica 60 GF254 plate as the stationary phase. Afterwards, plate was sprayed with HCl or KOH. The analyzed parameters were hRfc, normal UV-spectrum pattern and its shift. The correlation of spectrum or the shift of UV-spectrum for barbiturate compounds was determined with Wincats program.
The analysis of barbiturates which based on hRfc in error window (±7) for TD system and in error window (±11) for TE, still produced hit factor 8-25 compounds. The confirmation test for barbiturates based on hRfc and r ? 0,95, produced hit factor 1-2 compounds.
Barbiturate compounds showed spectrum shift in alkali solution, while in acid solution did not happen. However, all four analytes contained identical spectrum shift, therefore the data of these spectrum shift can not be utilized for confirmation test of barbiturate compounds.
