examined. The research was analyzed within the framework of public disclosure
and transparency, shareholder, stakeholders and board of directors, which has
both corporate subheadings and corporate governance total score. The study was
analyzed by using Panel Vector Autoregressive (PVAR) model for 2009-2016
periods. According to the results, corporate governance practice in Turkey is
not effective in buying stocks of investors. The corporate governance of the
companies is reflected negatively in the long term returns. Investor profile in
Turkey is not interested in how the company is generally managed, investors are
more care about short-term returns. It is thought that the corporate governance
of firms should be introduced more in order to become a long-term preference
for the investor.

Vários fatores interferem na produtividade da cultura do milho (Zea mays L.), destacando-se densidade de plantas e dose de nitrogênio (N). Objetivou-se, com este estudo, avaliar a interferência de densidades de plantas e doses de N, no cultivo de milho safrinha em Dois Vizinhos – PR. Foram avaliadas duas densidades de semeadura (45.000 e 55.000 plantas ha-1) e quatro doses de N (0, 50, 100 e 150 kg ha-1). Utilizou-se o delineamento em blocos ao acaso com parcelas subdivididas. A semeadura foi realizada em 15 de janeiro de 2015, utilizando o híbrido Dow AgroSciences 2B587Hx. As doses de N foram aplicadas em cobertura, quando as plantas estavam em estádio vegetativo V4. Foram avaliados os seguintes caracteres agronômicos: diâmetro do colmo, altura da primeira espiga, altura de planta, estande de plantas, quantidade de espigas, porcentagem de restolhos, fileiras por espiga, grãos por fileira, massa de 1.000 grãos e produtividade. Os dados foram submetidos à análise de variância, e, quando significativo, aplicou-se teste de média para as densidades e análise de regressão para as doses de N. Não foi constatada interação entre os fatores avaliados, porém o aumento da dose de N proporcionou acréscimo linear no diâmetro do colmo, altura de plantas, altura de inserção da espiga, massa de 1.000 grãos e produtividade. A densidade de 55.000 plantas ha-1 resultou em menor diâmetro do colmo e número de grãos por fileira, mas apresentou estande de plantas superior, com maior quantidade de espigas e consequentemente, maior produtividade de grãos, sendo adequada à cultura.

Published: October 2019

O Brasil é um importante player no cenário agrícola internacional e conta com uma vasta extensão de terras férteis. A adoção de novas tecnologias ao longo do processo produtivo proporcionou avanços significativos no campo, em especial no Estado do Mato Grosso maior produtor brasileiro de soja. Entretanto, a falta de investimentos em infraestrutura logística para suportar este desenvolvimento limitou o potencial de crescimento. Isto posto, o objetivo do artigo é desenvolver um sistema de avaliação de desempenho capaz de medir a eficiência das rotas logísticas para exportação da soja com base nas dimensões econômica, social e ambiental. Os resultados apresentados evidenciam o benefício da utilização da intermodalidade no escoamento da produção conectando as regiões produtoras aos portos tradicionais de exportação, como Santos-SP e Paranaguá-PR. Entretanto, novas rotas se destacam com destino aos portos conhecidos como Portos do Arco Norte, São Luís-MA e Santarém-PA, mas demandam de novos projetos logísticos capazes de promover a integração dos modais ferroviário e hidroviário aos terminais de transbordo e, a partir daí, para os portos de exportação.

Web technology and internet networks have made web applications the main tool in daily activities. But developing applications with limited time often leads to neglecting the role of the user, which causes a lack of attention to aspects of usability, which results in the failure of the application to meet the needs and desires of the user. In this study we developed an application for submitting credit number determination proposals for engineering functional positions by combining Incremental Prototyping and User Centered Design methods. The results show that the application can meet the usability aspects so that it is easily understood and used in submitting and evaluating proposed credit numbers.Teknologi web dan jaringan internet telah menjadikan aplikasi web sebagai piranti utama dalam kegiatan sehari-hari. Namun pengembangan aplikasi dengan keterbatasan waktu seringkali mengabaikan peran pengguna, yang menyebabkan kurangnya perhatian pada aspek usabilitas sehingga berdampak pada kegagalan aplikasi memenuhi kebutuhan dan keinginan pengguna. Dalam penelitian ini dilakukan pengembangan aplikasi pengajuan usulan penetapan angka kredit (DUPAK) untuk jabatan fungsional perekayasa  dengan menggabungkan metode Incremental Prototyping dan User Centered Design. Aplikasi yang dikembangkan terbukti dapat memenuhi aspek usabilitas sehingga dapat mudah dipahami dan digunakan dalam pengajuan dan penilaian usulan angka kredit.

Bu

araştırmada 4 farklı (350, 500, 650 ve 800 tohum m-2) ekim sıklığı

(ES) uygulamasının 6 ekmeklik buğday çeşidinin (Alpu01, Atay85, Bezostaja1,

Harmankaya99, Sönmez01 ve Sultan95) bazı kalite özelliklerine etkisinin

belirlenmesi amaçlanmıştır. Araştırma 2012-2013 ve 2013-2014 yıllarında Geçit

Kuşağı Tarımsal Araştırma Enstitüsü Eskişehir Merkez yerleşkesinde

yürütülmüştür. Denemeler tesadüf bloklarında faktoriyel deneme deseninde 3

tekerrürlü olarak kuru (yağışa bağımlı) ve sulu koşullarda yürütülmüştür.

Çalışmada iri tane oranı (İTO), ufak tane oranı (UTO), bin tane ağırlığı (BTA),

hektolitre ağırlığı (HLA), tane protein oranı (TPO), kuru gluten (KGL), zeleny

sedimentasyon (ZSD) ve sertlik değeri (SRD) gibi kalite unsurları

incelenmiştir. Araştırma sonuçlarına göre ES uygulamalarının kuru koşullarda

İTO, UTO, BTA ve SRD unsurlarına etkisi önemli (p<0.01) bulunurken, sulu

koşullarda sadece BTA unsuruna etkisi önemli (p<0.01) bulunmuştur. ES

artışları iki çevre de de İTO ve BTA değerlerini olumsuz etkilemiştir. Çeşitler

arası farklılıklar ise araştırılan tüm parametrelerde (p<0.01) önemli

bulunmuştur. Sönmez01 ve Bezostaja1 çeşitleri İTO, BTA ve HLA açısından;

Bezostaja1 çeşidi ZSD, TPO ve KGL açısından; Sultan 95 ise UTO ve SRD açısından

öne çıkmıştır. Gerek kuru gerekse sulu çevrede İTO ile UTO ve SRD arasındaki

olumsuz korelasyon; BTA, HLA, KGL ve ZSD arasında ise olumlu korelasyonun

Böcek türlerinin değişik bitki türlerine
ve elverişsiz çevre koşullarına adapte olarak hayatlarını sürdürebilir
kılmaları yeryüzündeki canlı türleri arasında en fazla türe sahip olmalarını
sağlayan önemli özellikleri arasında yer alır. Lahanagiller familyası, polifag bir tür olan lahana beyazsineği, Aleyrodes
proletella L. (Hemiptera:
Aleyrodidae)’nın önemli konukçuları arasında
sayılmaktadır.
Polifag türler konukçusu olan kültür bitkilerinin
yetiştiriciliğinin yapılmadığı dönemlerde alternatif konukçuları olan yabancı
ot türlerinde beslenerek yaşamlarını uzun süre devam ettirebilme özelliğine
sahiptirler. Aleyrodes proletella’nın
Entegre Mücadele (EM) programının oluşturabilmesi için zararlının kültür
bitkileri dışındaki alternatif konukçularının üzerinde oluşturduğu
popülasyonunun bilinmesi önem arz etmektedir. Düzce ilinde 2017-2018 yıllarında
karayaprak lahanası bitkilerinin çevresindeki yabancı ot, Lapsana communis L. (Bieb. Hayek) üzerinde A. proletella’nın çeşitli dönemlerinin
popülasyon takibi yapılmıştır. Bu amaçla, kış sezonunun bitiminde karayaprak
lahanası bitkilerinin araziden sökülüp imha edildiği dönemde bahçelerin
çevresinde tesadüfi olarak seçilen L.
communis bitkileri dikkatlice incelenerek beyazsineğin görülen biyolojik
dönemleri (yumurta, larva, pupa, ergin) kaydedilmiştir. Yabancı ot, L. communis üzerinde
beyazsinek, A. proletella’nın bütün biyolojik dönemlerinin görülmesi,
ilkbaharda Düzce koşullarında karayaprak lahanası bahçelerinin etrafında
bulunan yabancı otu A. proletella’nın
ara konukçu olarak kullandığını göstermektedir. Sonuç olarak L. communis’e karşı yapılacak
mücadelenin zararlı popülasyonunda azalmaya sebep olacağı bilinmekle birlikte,
yabancı otun aynı zamanda zararlının parazitoit ve predatörlerine de konukçuluk
yaptığı tahmin edilmektedir. Bundan sonra yürütülecek çalışmada karayaprak
lahanası bahçelerinin etrafındaki yabancı ot, L. communis’in A. proletella’nın
biyolojik mücadelesine olan etkisi araştırılmalıdır.

Yerel mercimek (Lens

culinaris Medik) genotiplerinin

ıslahı için gerekli olan öncelikli özelliklerin belirlenmesi ve özelliklere ait

kalıtım dereceleri ile genetik ilerleme değerlerinin ortaya konulması amacıyla

yürütülen bu çalışma Ahi Evran Üniversitesinin Tarımsal Araştırma ve Uygulama

arazisinde üç yıl süre ile sürdürülmüştür. Kırşehir ilinden toplanan ve

tanımlaması gerçekleştirilen 31 adet yerel mercimek genotipi bu çalışmanın

materyalini oluşturmuştur. Tesadüf Blokları Deneme Desenine göre üç

tekrarlamalı olarak kurulan çalışmada incelenen değişkenlere ait tanımlayıcı

istatistikler ile değişkenlere ait varyanslar ve kalıtım dereceleri ortaya

konulmuştur. Çalışma sonucunda bitkide bakla sayısı ile bitkide tane sayısı

karakterlerinin kalıtım derecesi değerleri bakımından önde geldiği görülmüş

olup bu karakterlerin aynı zamanda fenotipik, genotipik ve genotip x yıl

etkileşim varyanslarına ait değişim katkılarının da yüksek olduğu ortaya

konulmuştur. Buna göre yerel mercimek genotiplerinin ıslah programlarında daha

başarılı bir şekilde değerlendirilebilmeleri için bu karakterler üzerinde

özellikle durulması yararlı olacaktır.

The aim — to evaluate the efficiency of the antiseptic gel used for peritoneal lavage in generalized peritonitis in the experimental and morphological study.Materials and methods. The experimental and morphological study was conducted with 80 lab rats. the rats were divided into 4 groups depending on the antiseptics utilized for peritoneal lavage: in I group (n = 20) — chlorhexidine gluconate 0.02 %, II group (n = 20) — Decamethoxinum 0.02 %, III group (n = 20) — antiseptic gel (hyaluronic acid based Decamethoxinum), IV control group (n = 20) — 5 ml of normal saline were used. The bacteriological examination and enterotomy of the small intestine (0.2 — 0.3 cm) followed by suturing of this defect with Vicryl were performed in all groups after laparotomy, before abdominal sanitation.Results and discussion. The results of a morphological study of the parietal and visceral peritoneum after sanitization of the abdominal cavity with antiseptics indicate a high efficiency of the antiseptic gel solution compared to a 0.02 % solution of chlorhexidine bigluconate, as evidenced by a decrease in interstitial edema of the parietal and visceral peritoneum, inflammatory cell infiltration, the absence of adhesions, adequate regenerative processes in the affected area, lack of adhesions between the loops of the intestine, mesothelium regeneration.Conclusions. Antiseptic gel solution can be used for intraoperative and postoperative abdominal sanitation in the complex treatment of patients with generalized peritonitis.
