On MDS Negacyclic LCD Codes

Linear codes with complementary duals (LCD) have a great deal of significance amongst linear codes. Maximum distance separable (MDS) codes are also an important class of linear codes since they achieve the greatest error correcting and detecting capabilities for fixed length and dimension. The construction of linear codes that are both LCD and MDS is a hard task in coding theory. In this paper, we study the constructions of LCD codes that are MDS from negacyclic codes over finite fields of odd prime power $q$ elements. We construct four families of MDS negacyclic LCD codes of length $n|\frac{{q-1}}{2}$, $n|\frac{{q+1}}{2}$ and a family of negacyclic LCD codes of length $n=q-1$. Furthermore, we obtain five families of $q^{2}$-ary Hermitian MDS negacyclic LCD codes of length $n|\left( q-1\right)$ and four families of Hermitian negacyclic LCD codes of length $n=q^{2}+1.$ For both Euclidean and Hermitian cases the dimensions of these codes are determined and for some classes the minimum distances are settled. For the other cases, by studying $q$ and $q^{2}$-cyclotomic classes we give lower bounds on the minimum distance

A research on determination of effects of different lateral spacing and irrigation programme for drip irrigated cotton in Aydın province

This research was conducted to determine the effect of different lateral spacing and irrigation levels on seed cotton yield and some quality and agronomic paremeters of cotton in the Research and Application Farm of Faculty of Agriculture at Adnan Menderes University during the year of 2009. Experiment was set up out in randomized plot design with two factors and three replications. Trials comprised two lateral spacing (0.70 m – 1.40 m) within each of which three different watering regimes (100, 75 and 50 % of 8 day cumulative calss-A pan evaporation) were applied. The results revealed that lateral spacings and irrigation levels affected the seed cotton yield and the highest yield was observed as 648,6 kg/da at full irrigation level of 100 % (T4) of control plot and in 1.40 m of lateral spacings. The lowest yield was observed as 537.2 kg/da from 50 % (T3) treatment . Maximum water use was determined in the T1 treatment as 723.4 mm; and the lowest water use was in the T6 treatment with 495.6 mm. Lateral spacings and the amount of irrigation water applied were both affected the fiber thickness, fiber length, fiber strength, number of bolls per plant, boll weight, 100 seed weight, lint percentage, number of generative branches. L2 lateral irrigation water applied in the range of 100% of subjects were found to be more appropriate in the economic sense.Adnan Menderes Üniversitesi Ziraat Fakültesi Araştırma ve Uygulama Çiftliğinde 2009 yılında yürütülen bu çalışmada, pamukta farklı lateral aralığı ve su düzeylerinin kütlü pamuk verimi ile bazı kalite ve agronomik özellikler üzerine etkisi araştırılmıştır. Araştırma üç tekerrürlü ve iki faktörlü tesadüf blokları deneme desenine göre kurulmuştur. Denemelerde 0.70 ve 1.40 m lateral aralıklarında A sınıfı buharlaşma kabında oluşan 8 günlük birikimli buharlaşmanın %50, %75 ve %100'ünün karşılandığı üç su düzeyi incelenmiştir. Sonuçta lateral aralığı ve su düzeylerinin kütlü pamuk verimini etkilediği, en yüksek verimin her iki sıraya bir lateral hattınns erildiği sistemde yer alan ve tam sulama suyu uygulanan T4 (%100) kontrol parselinden 648.6 kg/da olarak elde edilmiştir. En düşük verim ise 537.2 kg/da her sraya bi lateral hattın serildiği T3 (%50) parselinden elde edilmiştir. En yüksek su tüketimi her sıraya bir lateral hattın serildiği ve tam su alan T1 konusunda 723.4 mm; en düük su tüketimi her iki sıraya bir lateral hattın serildiği ve %50 oranında su aan T6 konusunda 495.6 mm olmuştur. Araştırmadan sonuçlarına göre gerek lateral aralığının gerekse su düzeyinin lif inceliği, lif uzunluğu, lif mukavemeti, çırçır randımanı, yüz tohum ağırlığı, bitki boyu, koza sayısı, koza ağırlığı, meyve dalı sayısı ve silkme oranına etkisinin önemli olduğu belirlenmiştir. L2 (1.40 m) lateral aralığında % 100sulama suyu uygulanan konuların ekonomik anlamda daha uygun olduğu tespit edilmiştir

Hafız Divan’ının İki Yeni Türkçe Tercümesi Dolayısıyla: Hafız Divanı’ndaki İlk Gazelin İlk Beytinin Türkçe Tercümesi Üzerine Bazı Notlar

Hafız Divanı’ nın yarm asra yaklaşan bir aradan sonra, son yıllarda iki tercümesi birden yapıldı. Mehmet Kanar ve Hicabi Kırlangıç tercümesi. Ama edebiyat dünyası yankısız, sessiz kaldı. Biz bu değerli çalışma ve emeğe saygı olarak, onların Hafız Divanı çevirisine değinmek istedik. Bu iki tercümeye, dört isim daha ekledik. Böylece altı tercümeye yer verdik. fakat bu tercümelere bir örnek olarak sadece Hafız Divanı’nın ilk gazelinin ilk beytini kapsamaktadır. Yani ilk gazelin ilk beytini, Sudi, Mehmet Vehbi Konevi, Abdülbaki Gölpınarlı, Rüştü Şardağ, Mehmet Kanar ve Hicabi Kırlangıç nasıl tercüme etmişler? Bunu göstermek istedik

The effects of plant biostimulants and plant growth regulator applications on plant growth in lilium 'Adelante'

  This experiment was designed, it was determined the effects of mycorrhiza, vermicompost, promalin applications on development of plant properties in a bulbous plant, Lilyum 'Adelante. Flower branch length (cm), flower branch diameter (mm), internode number, flower bud number, flower bud length (cm), flower stem length (cm), flower width (cm), flower length (cm), number of leaves and leaf length (cm) were measured. The results showed that no treatment increased plant height more than control plants, but each application had different effects on other plant characteristics. As a matter of fact, mycorrhiza increased internode number, flower bud number, flower bud length, flower stem length, flower length, number of leaves and leaf length by 6.3%, 15.6%, 14.2%, 6%, 40%, 10.3%, 2.9% and 6%, respectively. Vermicompost increased flower bud length, flower length and leaf length by 6.6, 12, 15.3% and 16.1%, respectively. Promalin, on the other hand, increased the flower stem length, flower length and leaf length by 56.3% and 15.4%, respectively. The application of mycorrhiza together with Promalin did not have a different effect than the application of Promalin alone, and even showed a lower effect than the application of Promalin alone. Mycorrhiza, on the other hand, was the application that showed the best effect compared to other applications. Therefore, it can be recommended for plant growth in lilies. However, due to the effect of application time and dose on flowering time, it is possible to obtain different results in plant development in lilies.  This experiment was designed, it was determined the effects of mycorrhiza, vermicompost, promalin applications on development of plant properties in a bulbous plant, Lilyum 'Adelante.

Prediktivno modeliranje distibucije potencijalnog staništa za anatolskog leoparda (Panthera pardus tulliana Valenciennes, 1856) u Turskoj korištenjem modela maksimalne entropije

The Anatolian leopard (Panthera pardus tulliana Valenciennes, 1856) is the largest surviving cat species in Türkiye. Despite the adversity they face, leopards still exist in Türkiye. In this study, using the maximum entropy model (MaxEnt), potentially suitable habitats for the Anatolian leopard in Türkiye was surveyed. When evaluating leopard habitat preference, the fact that the species can easily adapt to its habitat and live anywhere with sufficient vegetation and sufficient prey animals was taken into account; only data on climate which affects the geographic distribution patterns and population structures of flora and fauna were examined before. When the climatic variables affecting leopard’ distribution were examined, the following had the highest values: isothermally, seasonal temperature, average temperature of the coldest season, minimum temperature of the coldest month, and annual precipitation. Except for the Central Anatolia Region and coastal areas, almost every region in Türkiye contains habitats suitable for the leopard. There are scarce data on leopards’ populations and habitats in Türkiye. Therefore, even though ecological niche modelling (ENM) may generate important results when determining potentially suitable habitats, it is clear that this model cannot yield accurate results without considering the areas that the species is known to inhabit but in which no studies were previously conducted. The results that were obtained in the present study can also provide background information related to the long-term conservation of this species.Anatolski leopard (Panthera pardus tulliana Valenciennes, 1856.) je najveća preživjela vrsta mačaka u Turskoj. Unatoč nedaćama s kojima se suočavaju, leopardi još uvijek postoje u Turskoj. U ovoj studiji istražena su korištenjem modela maksimalne entropije (MaxEnt), potencijalno pogodna staništa za anatolskog leoparda u Turskoj. Prilikom procjene preferiranog staništa leoparda, u obzir je uzeta činjenica da se vrsta može lako prilagoditi svom staništu i živjeti bilo gdje ako ima dovoljno vegetacije i lovine; jedino su podaci o klimi koja utječe na zemljopisne obrasce rasprostranjenosti i populacijske strukture flore i faune prethodno ispitani. Nakon ispitivanja klimatskih varijabli koje utječu na distribuciju leoparda, dobivene su sljedeće najviše vrijednosti: izotermno, sezonska temperatura, prosječna temperatura najhladnijeg godišnjeg doba, minimalna temperatura najhladnijeg mjeseca i godišnja količina oborina. Osim regije središnje Anatolije i obalnih područja, gotovo svaka regija u Turskoj sadrži staništa pogodna za leoparda. Nema puno podataka o populacijama i staništima leoparda u Turskoj. Stoga, iako ekološko modeliranje niša (ENM) može proizvesti važne rezultate pri određivanju potencijalno prikladnih staništa, jasno je da ovaj model ne može dati točne rezultate ako ne uzmemo u obzir područja za koja znamo da ih ta vrsta naseljava, ali u kojima još nisu provedena istraživanja. Rezultati dobiveni u ovoj studiji mogu dodatno doprinijeti već poznatim informacijama vezano uz dugoročno očuvanje ove vrste
